Dr.T.N Pattabhiraman Oration-Laboratory Overload: How to Optimize?
Brig MM Arora
Professor & Head, Dept of Biochemistry, Armed Forces Medical College, Pune-411040. Email:
[email protected]; Lt. Col. (Mrs) J.k Bhatia, MD, Classified specialist pathology, Military
Hospital, Dehradun (UP)
Background: Medical fraternity requisitions
diagnostic tests for multiple reasons. More often
than not, the tests lead to more tests either to
exclude or to confirm doubts raised by the test
results. These tests do have inherent morbidity,
discomfort and cost. Growing expenditure on
diagnostic tests without matching improvement
in the health status warrants an internal audit of
the laboratory utilization.
Methods: A retrospective utility audit was done
for certain routinely advised laboratory tests. Tests
included in audit were blood urea estimation in
annual as well as periodic medical examination;
bleeding and coagulation time in pre-anesthetic
check-up; and aspartate aminotransferase (AST);
antibodies to hepatitis C virus (anti-HCV) in
diagnostic work-up of acute onset jaundice; and
T3, T4, TSH estimation in evaluation of thyroid
function.
acute onset jaundice, 6049 AST estimations in
1024 patients did not contribute anything more
than what was inferred by alanine aminotransferase
(ALT). Prevalence of anti HCV antibodies in acute
onset jaundice in serving soldiers (11 out of 1225;
0.89%) though more than that in the blood donors
from the same population (17 out of 4105; 0.41%)
was less than anticipated false positives (18 out of
1225; 1.5%) as per the claimed specificity (98.5%)
of the test kit. None of the 2766 bleeding and
clotting time tests detected a bleeding or
coagulation disorder. Despite sizable evidence in
favour of TSH being an adequate single screening
test for evaluation of thyroid, the ordering
frequency of T3, T4, and TSH was nearly the same.
Conclusion: The study reveals gross overuse of
the laboratory that may not be good for the patient
and the organization in terms of direct costs as well
as indirect costs due to false positive results. To
make the matters worse, this laboratory overload

Regenerative Nanomedicine - Prospects for Diagnostics and Therapy using
Nanomaterials
Shanti Kumar Nair
Dean of Research, Head of Nanotechnology Division, Amrita Institute of Medical Colllege, Kochi.
Nanotechnology has shown great potential as a for augmenting the body’s healing capacities in
primary diagnostic and therapeutic tool in the the area of regenerative medicine through novel
medical sciences. It has also shown its potential approaches such as tissue or organ engineering.
46
The diagnostic potential of nanotechnology has
been advanced by the development of novel
nanoparticles with luminescence or
superparamagnetic or scintillator properties. Such
nanoparticles can be tagged to diseased tissues,
such as cancer cells and detected by their relevant
scale-modulated property.
Tagging of
nanoparticles to cells has emerged as a new science
involving interaction of chemical moieties with
the nanoparticle surface and with the cell
membrane or with monoclonal antibodies.
Successful tagging of nanoparticles has opened
the door to cell-specific rather than systemic
therapy. In cell-specific therapy the drugs are
delivered specifically to the target cells by
conjugating the drugs with the nanoparticles or
encapsulating the drugs within nanoparticles.
Other therapeutic approaches involve
photodynamic or thermal therapies which do not
involve highly toxic chemotherapeutic agents. In
regenerative medicine also nanotechnology has
shown the potential to enhance the regenerative
ability by its ability to control cell-material
interactions. The control of cell-material
interactions using nanomaterials has emerged as
a new and dynamic science with great potential
for healing and regeneration of tissues and organs.
In this presentation the author will present some
of the data from his own lab as well as some data
from other leading scientists in the area.

Endothelial Dysfunction with Special Reference to eNOS Gene Polymorphism:
Another Plausible Mechanism for CAD Risk in Postmenopausal Women
Jayashree Bhattacharjee
Department of Biochemistry, Lady Hardinge Medical College, New Delhi, India
Background: Framingham study indicates more
than two fold age related increased risk of
Coronary artery disease (CAD) in postmenopausal
women as compared to premenopausal women.
Nitric Oxide (NO) is an important regulator of
endothelial functions and has several cardio
protective actions as vasodilation, inhibition of
platelet aggregation & adhesion. The Glu298Asp
polymorphism of endothelial nitric oxide synthase
gene (eNOS) is associated with CAD risk.
Estrogen exerts its local vasodilating and
antiplatelet actions as a consequence of endothelial
response mediated by release of EDRF (endothelial
dependent relaxing factor), which is NO.
other established CAD risk markers for the purpose
of early diagnosis and intervention.
The purpose of this study was to assess CAD risk
in postmenopausal women by evaluating Nitric
oxide – Cyclic GMP signal transduction pathway
& screening Glu298Asp polymorphism along with
Results: Plasma NO, Estrogen and HDL levels
was found to be significantly lower (P<0.05) while
VLDL and Apo-B levels shown significant
increase (p<0.05) in postmenopausal women cases
Methods: Two consecutive studies were
conducted. Each study design consists of 50
postmenopausal women cases compared with 50
premenopausal women controls for similar age
group excluded for any known CAD risk. In the
first study we measured the levels of NO, Estrogen,
Apo-B and functional relation of NO and cGMP
to evaluate signal transduction pathway. The
second study was done to investigate the associated
role of Glu-Asp298 eNOS gene polymorphism &
platelet function in increasing postmenopausal
CAD risk.

as compared to Premenopausal women controls.
Plasma cGMP levels were significantly lower
(P<0.05) in cases than controls. A significant
positive correlation was observed between NO and
estrogen (P<0.01) whereas negative correlation
was found between NO and PF4 (P<0.01).
The GG genotype was found in 41 subjects (82%)
of the study group and 45 subjects (90%) of the
control group while GT genotype was seen in 9
subjects (18%) of study group and 5 subjects
(10%) of control group. No TT genotype was
found. The significant decrease was observed in
NO levels of GG+GT, GG and GT genotypes of
study group as compared to control group.
Conclusion: the low no and low cgmp activity
found in our study reflects defect in no-cgmp signal
transduction which leads to endothelial
dysfunction. as cad is a multifactorial disease, other
factors might also play a major role in endothelial
dysfunction to increase cad risk in postmenopausal
women. observations found in our study suggest
that enos glu298asp gene polymorphism and nitric
oxide levels may be associated with an increased
risk of coronary artery disease in postmenopausal
women. further studies are needed to explore more
mechanistic basis of the association which in turn
will modify therapeutic and diagnostic strategies.

Tyrosine Kinases from Basic Science to Therapy
T.S.Ganesan
Chairman, Cancer Institute & Institute of Molecular Medicine,Amrita Institute of Medical Sciences,
AIMS P.O. Kochi, Kerala, 682 041
Protein phosphorylation is a central event in cellular physiology. Phosphorylation on tyrosine residues by tyrosine kinases is particularly important
as it is subverted in malignant transformation. This
is apparent with the discovery of a number of
oncogenes which are tyrosine kinases. It is now
clear the number of families of tyrosine kinases
in the human genome and is restricted to meta-
zoans. Research into the role of tyrosine kinases
in malignant transformation has uncovered many
new targets for treatment. The first such kinase is
the ‘abl’ kinase, but more kinases are now
druggable. This whole area of research represents
an excellent examples of how basic research has
led to discovery of new treatments for cancer.

Lead Poisoning: Current Status in Developing Countries and the Global Perspective.
Thuppil Venkatesh
Professor Emeritus. St John’s Medical College Bangalore and Principal Advisor Quality Council of
India, Delhi.
Lead being one of the toxic heavy metals globally considered as the number one environmental and
48
health hazard affecting people of all age groups
has maximum effect during growth and
development of children. With its deleterious
effects on all organs in the human body, lead
poisoning is widely recognized as a major public
health problem all over the world. Children and
women are found most vulnerable to lead
poisoning especially in developing countries.
Unlike other health hazards, lead poisoning is
hundred per cent preventable when legislation is
in place.
The estimate by the World Health Organization
has indicated that over 120 million people are
overexposed to lead all over the world and 99
percent of the most serious cases are in the
developing world. The project Lead Free of The
George Foundation was initiated in Bangalore and
its vicinity, and subsequently expanded to several
other major cities across India), found that more
than 51.3 per cent of children in Indian metros
below 12 years of age have their blood lead levels
above 10 ug/dl. Blood lead levels above 10ug/dl
is known to reduce the IQ during growth and
developmental phase of children. An average
reduction of IQ to an extent of 4-6 units on a scale
is known to result in the economic damage to
countries to the tune of over Rs 600 crore annually
by 2015.
Author was involved in the introduction of
unleaded gasoline in India in March 2000, and has
recently found out other major sources such as
lead based traditional medicines and lead-based
paints. Detailed studies by the author has indicated
that though the per capita consumption of paints
in India is around one-fifteenth of developed
countries with a demand as on date with the
unprecedented boom in the housing sector which
is expected to satisfy the demand for over 30
million new homes which is a great threat to the
countries future economy. A study report by the
author during 2006 on the analysis of lead in paints
in China, India and Malaysia revealed that over
80 new paints from these countries used in homes
had very high lead levels — in fact, exceeding the
levels of 1000 ppm. Though there is a need for
the ban of lead-based paints all over the world,
which has been emphasized time and again to
prevent exposure and associated sicknesses,
developing countries have not taken this seriously.
In India, for example, lead-based paints were found
in the homes of three children whose blood lead
levels were at least 40 ug/dl. In a report on dust
lead levels in Delhi, homes had dust with lead
levels of 31 per cent. That incidentally exceeds
the current US limit of 40 ug/sq ft.
Apart from this almost 80% of all the lead now
used in many parts of the world is for the
production of lead-acid batteries and that in India
and other developing countries the environmental
friendly recycled lead is of much lower proportion
in lead acid battery manufacturing causing another
major threat to both environment and health.
Author is involved in the development of the BEST
certification program to all lead acid battery
industry in the country with wide acceptability.
With the recent efforts to create lead map of two
megacities in India the National Referral Center
for Lead Poisoning in India established by the
author with several branches all over the country
is conducting lead educator program sponsored by
QCI is working towards lead safe society.

used. A group of genes was found that is up-regulated by αTP but not by αT; suggesting that in some
cells αT is not sufficiently converted to αTP. Genes
which were regulated by both compound were

Impact of Pharmacogenetics on Therapeutic Drug Monitoring
M. Oellerich, V.W. Armstrong and N.Von Ahsen
Department of Clinical Chemistry, George-August-University Göttingen, Germany
Pharmacogenetics and its application to TDM is
an emerging field. Gene test guided therapy could
facilitate the selection of a drug and its dosage to
which the patient best responds. A future goal may
be a pharmacogenetic patient card. Valid
pharmacogenomic biomarkers listed by the FDA
include drug metabolising enzymes (CYP2C9+,
CYP2C19, CYP2D6, DPD, NAT, TPMT + ,
UGT1A1 + ) as well as HLA-B*5701 + and
VKORC1+. Genomic biomarkers for which testing is recommended are marked (+). There is a lack
of evidence supporting a clear association between
ABCB 1 (MDR1) genotype and clinical drug response or toxicity. Variability of P-glycoprotein
expression can affect intralymphocyte concentrations of cyclosporine. It could be demonstrated
that the intracellular T-lymphocyte cyclosporine
concentration has a potential for predicting rejection. The CYP2D6 polymorphism plays an important role in the metabolism of antipsychotic as
well as antidepressant drugs and tamoxifen. Due
to multiple copies of a functional allele in
ultrarapid metabolisers, a standard dose of antipsychotic or antidepressant drugs leads to low
plasma concentrations and a lack of therapeutic
effect. Ultrarapid metabolisers are predominantly
found in Saudi Arabia and Ethiopia (allele frequency 10 – 29 %) and according to our own investigations in Papua New Guinea populations (12
%). Tamoxifen is used for the treatment of patients
with hormone-dependent breast cancer. It is converted by CYP3A and CYP2D6 to active metabolites which are more potent than the parent drug.
Time to disease progression was significantly
shorter in Asian patients treated with tamoxifen
who were poor metabolisers (CYP2D6*10/*10),
compared with other genotypes evaluated.
CYP2D6 genotyping may help to identify breast
cancer patients who will benefit from tamoxifen.
Thiopurine-S-methyltransferase (TPMT) deficiency causes azathioprine intolerance accompanied with severe myelosuppression. Testing for
TPMT phenotype/genotype is a useful practice for
a safer management of patients requiring
thiopurine drugs. An inosine triphosphatase mutation (ITPA 94C>A) appears to be a further promising marker for azathioprine interolerance. A polymorphism in the CYP3A5 gene leads to deficiency
of the enzyme and may in part contribute to
interindividual differences in CYP3A dependent
drug clearance. Recent investigations have shown
a significant difference in dose-adjusted tacrolimus
blood levels between CYP3A5 expressors compared to non-expressors. HLA-B*5701 genotyping
is useful to identify patients at greatest risk for a
hypersensitivity reaction to abacavir. Genomewide assessments of gene expression are increasingly being used and, e.g., have identified
SLCO1B1 variants that are strongly associated
with statin-induced myopathy. Expression profiling has the potential to identify gene-expression
patterns related to drug response. Both approaches
may be complementary and take into account that
the response to most drugs is influenced by multiple genes. Drug disposition marker genotyping
is a promising tool in addition to TDM for
individualisation of drug dosing with the goal to
improve the efficacy and safety of pharmacotherapy.

The role of Bone Turnover Markers in Clinical Management of Osteoporosis
SD Vasikaran
Royal Perth Hospital, Perth, Australia
The diagnosis of osteoporosis is based on bone
mineral density measurement (BMD). The
decision to treat is better assisted by the calculation
of absolute fracture risk, which incorporates age
and clinical risk factors in addition to BMD.
Current algorithms for the calculation of fracture
risk do not incorporate bone turnover markers
since there are inadequate data for their use in risk
calculation. In clinical practice bone turnover
markers may help make cost effective treatment
decisions in patients with borderline absolute risk.
Bone turnover markers which show an early
response following commencement of treatment
are useful for the monitoring of therapy for
osteoporosis for which the use of BMD is
increasingly being questioned. The use of bone
turnover markers helps to identify non-compliance
and non responders early. In addition to the above
issues, this talk will address individual bone
turnover markers which are of most value in
clinical practice.

A New Diagnostic Paradigm: Some Enabling Technologies
Ross Barnard
School of Chemistry and Molecular Biosciences, The University of Queensland,
St.Lucia Qld, Australia
The traditional approach to diagnosis is one that
has been practised since the time of hippocrates.
It entails forming an hypothesis (a presumptive
diagnosis) followed by design of specific tests to
refute or confirm the presumptive diagnosis.
Until recently this has been the basis for design
of molecular tests for microrganisms, including
viruses. A persistent problem is differential
diagnosis, when presentation is similar for a
range of possible infectious agents (for example,
a wide range of arboviruses; H5N1 (“avian”)
versus H1N1 (“swine”) or H3N8 (“equine”)
influenza). There are several forces operating to
move us away from this model towards a “one
test model. These are: 1) a need to quickly detect
52
unknown, unanticipated or emerging pathogens, 2)
the pressing need to rapidly acquire more
clinically useful information about pathogens (for
example drug resistance, host preference and
pathogenicity “signatures” in influenza a, 3)
multiplexing, that is, performance of many tests
simultaneously and 4) the need for point-of-care
or field testing. These forces are driving
innovation in molecular methods, bioinformatics
and devices. Some examples of these innovations
will be given from our work on flavivirus testing,
influenza a testing, virus drug resistance testing
and a new, multiplexable, real time pcr
technology.

The Natural Phenolic, Malabaricone B Selectively Kills the Cancer Cells through
Mitochondrial Pathway
S. Chattopadhyay
Bio-Organic Division, Bhabha Atomic Research Centre, Mumbai – 400085, India.
Redox dysregulation originating from metabolic
alterations and dependence on mitogenic and survival signaling through reactive oxygen species
represents a specific vulnerability of malignant
cells that can be selectively targeted by redox chemotherapeutics. Simultaneous modulation of multiple redox sensitive targets by these agents can
overcome cancer cell drug resistance, a common
impediment of anti-cancer drug development.
Search for suitable experimental chemotherapeutics that induce positive deviations from redox homeostasis through prooxidant action has therefore
drawn much attention. A wide array of natural phenolics, such as turmeric, epigallocatechin gallate,
resveratrol, as well several established drugs such
as bleomycin, cisplatin, etoposide and paclitaxel
exert their anti-cancer action through the
prooxidant mechanism. The diarylnonanoid,
malabaricone B, isolated from the Indian spice,
Myristica malabarica was found to possess
chemopreventive property against A549 (human
lung carcinoma), A375 (human malignant melanoma), and Jurkat (human T cell leukemia) especially the A549 cells. It caused apoptotic killing
of the A549 cells via activation of caspase-9 and
caspase-3, but not caspase-8 by altering the BaX/
Bcl-2 ratio. This revealed the mechanism of its
action was primarily linked to mitochondrial damage, inducing the release of cytochrome c into the
cytosol and apoptosome complex formation. The
mal B-induced mitochondrial depolarization, subsequent cytochrome c release and cell cycle arrest
were also confirmed with the A549 cells. Interestingly, the cytotoxicity of the phenol proceeded in
a p53-independent manner, as revealed from our
results with stably transfected A549- p53 cells.
Mutation of the tumor suppressor protein p53,
which serves as a pivotal component of the
apoptosis pathway(s) is believed to be an important factor in poor prognosis of cancer and plays a
critical role in the resistance of cancers to radiation and chemotherapy. Also, compared to the
DNA targeting compounds, chemotherapies,
aimed at mitochondrial inhibition can selectively
kill tumour cells. In view of these, and our results
with malabaricone B on the A549 cells suggested
it to be a promising anti-cancer agent for further
evaluation

The ocean has always been a rich source of food
and medicines for humans. Fairly recently, researchers have turned to the sea for alternative
sources of medicinal drugs and supplements for
health and wellness. However, procedures for the
extraction of bioactive components from marine
organisms vary from researcher to researcher. We
tested the efficiency of various popular protocols
used in different labs and estimated various antioxidant and free radical scavenging activities as
53
markers for efficient extraction of antioxidants
from 2 species of brown algae, Padina
tetrastromatica and Turbinaria ornata. The best
protocol was 72 hours sequential extraction at
room temperature with hexane, followed by
dichloromethane, acetone, ethyl acetate and
methanol. The activities estimated were the FRAP
value, scavenging activities for the DPPH radical,
the superoxide anion, and the hydoxyl ion, total
phenolic content as well as the antiproliferative
activity towards two breast cancer cell lines.

Male Infertility: Role of Oxidative Stress and Some Possible Herbal Remedies
Abbas Ali Mahdi, Mohd. Kaleem Ahmad, Kamla Kant Shukla,

Departments of Biochemistry and *Urology, C.S.M. Medical University, Lucknow-226003, **Central
Drug Research Institute, Lucknow-226001, ***State Government T.T. College (Unani Medical
College), Lucknow-226003.
Infertility may be defined as failure to conceive
by a couple after 12 months of unprotected sexual
intercourse. Infertility affects 15% of all couples
and approximately 50% of these have an
abnormality detectable in the male partner as the
cause of infertility. Specific and directed treatment
for male infertility is not available due to
unexplained and heterogeneous nature of the
disorders. Under such circumstances, only assisted
reproductive techniques are of some help.
However, these treatments are expensive and
inaccessible to all. The lack of available specific
therapies for men with infertility demands the
exploration of alternative therapies. Given the lack
of knowledge about etiological factors, a nondirected but general therapy may yield good
results in a subcategory of patients. The rationale
for the use of these therapies is based on the
speculation that some forms of male infertility are
caused by oxidative insult and hormonal
imbalance and the use of alternative therapies may
improve male fertility potential and semen quality.
Ayurveda and Unani systems of medicine have
documented several Indian herbs which have been
in use for treatment of various disorders of male
reproductive system. Many scientific studies have
documented the beneficial effect of treatment of
infertile men with these plants, supporting the
54
literature regarding their medicinal usage. After
an in depth search of literature, we came across
more than 25 plants, the parts of which had been
used in male infertility treatment. On the basis of
information available, we made a priority list of
the plants for scientific studies. We conducted
studies in infertile men using seeds of Mucuna
pruriens and root powder of Withania somnifera.
Both these plants were highly beneficial in treating
male infertility. The plants were particularly helpful
in alleviating oxidative stress, which may be one
of the reasons for their beneficial effect. W.
somnifera had better anti-oxidant properties than
M. pruriens. We also conducted experiments on
normal and fertility compromised rats using these
plant products. We could replicate the results in
rats as far as improvement in spermatogenesis is
concerned. The current status of scientific studies
on fertility enhancing plants and the results from
our own studies on male infertility treatment will
be discussed in detail during the presentation.

[(E)-HST-1], 3’-5’ Hydroxylated Congener of Resveratrol, A Better Anticancer Agent
Sandip K Bandyopadhyay
Department of Biochemistry, Institute of Post Graduate Medical Education & Research KPC Medical
College & Hospital, Kolkata.
Resveratrol is potentially of interest for the treatment of different cancer but its use was constrained
because of its ulcerogenic adversative effects. We
have already reported that 3‘ -5 hydroxylated congener [(E)-HST-1] of Resveratrol was devoid of
ulcerogenic properties; hence in this study we
compared its chemopreventive potential with
Resveratrol in different cancer cell lines and analyzed the probable molecular mechanism of its
action. Our results revealed that HST-1 could exert better antiproliferative effects on different cancer cell lines compared to Resveratrol but showed
least toxicity to normal cells. HST-1 treatment
induced apoptotic cell death as evident from
externalization of phosphatidylserine, DNA fragmentation and cell cycle arrest at G0/G1 phase. In
our pursuit to dissect molecular mechanism the
cells were treated with caspase inhibitor which
confirmed the involvement of caspase-3 and
caspase-9 in HST-1 treated apoptosis.To confirm
the activation of mitochondrial death signal, the
change in membrane potential was analyzed in
HST-1 treated cells which was further substantiated by the release of cytochrome c in cytosol
from mitochondria. Our intricate investigation revealed that HST-1 treatment elicited intracellular
ROS generation and pretreatment of intracellular
ROS scavenger NAC gave significant protection
to the cells treated with HST-1 . NAC treatment
prevented the loss of mitochondrial membrane
potential and also reduced the cytochrome c releases followed by inhibition of caspase activation in HST-1 treated cells. These observations thus
confirmed that HST-1 a potentially better congener of Resveratrol exerted chemopreventive effects
through mitochondrial death cascade which is
modulated mainly by generation.

Oxidative Stress Management: Therapeutic Approach for Depression

J. N. Medical College, A.M. University, Aligarh, U.P., India, [email protected]
Objective: Anomalies in oxidative biology are
now recognized as a critical pathophysiological
mechanism for stress and depression. Biochemical
evidence that depressive behaviour is indeed
associated with deficits in the protective
antioxidant system is still lacking. Recently we
showed that augmentation of in vivo antioxidant
defenses might provide a convergence point for
the neuroprotective effects of different
antidepressants used for treating stress disorders.
On the basis of these findings, we tested the
hypothesis that micronutrients like folic acid and
ascorbic acid could conversely induce an
antidepressant-like effect in rodents.
Methods: The impact of chronic treatment with
folic acid, ascorbic acid or the SSRI fluoxetine
was investigated on the behavioural outcomes of
chronic restraint stressed rats in association with
assessment of brain antioxidant status, biomarkers
of oxidative damage, changes in body weight
and histological lesions.
Results: Restraint stress caused anhedonia and
behavioural despair, along with depletion of
antioxidants SOD, CAT, GST, GR, GSH, and
increase in lipid peroxidation and protein carbonyl
contents. As with ascorbic acid, treatment of
restraint-exposed animals for 21 days with folic
acid reversed the altered antioxidant defenses.
Stress induced behavioural changes were
attenuated by both folic and ascorbic acids, similar
to fluoxetine, with the normalization of decreased
body weight and restoration of brain
histopathological alterations.
Conclusion: The results indicate that changes in
depressive behavior and body weight are
associated with remarkable modulation of
oxidative stress and antioxidant defenses. Since
oxidative stress triggers/exacerbates several routes
of damage contributing to brain dysfunction and
this could be an important therapeutic target for
stress-related disorders like depression.

Antioxidant Potential and LDL Oxidation in Disease.
Dr. Neelima Singh and Nivedita Singh.
Department of Biochemistry, G.R. Medical College Gwalior (M.P)
LDL particles are rich in antioxidants and are
resistant to oxidation. The capacity which prevents
the oxidation of LDL by free radicals is known as
antioxidant potential (AOP). Diabetics are at
higher risk of atherosclerotic cardiovascular
diseases (ASCVD) than non diabetic. Present
study which is carried out in 20 healthy control,15
56
regulated D.M (by medicines) and 20 unregulated
diabetic mellitus subjects reveals that sensitivity
for LDL oxidation is increased significantly in
unregulated diabetes mellitus subjects (P<.001) as
compared to regulated diabetic group and control

Total Quality Management in Health Laboratories
Dr. Ghassan Shannan
IFCC Treasurer, E-Mail: [email protected]
Total Quality Management Concepts in Health
Laboratories became a necessity in analytical
laboratories. In USA and Europe various standards
are used to implement and enforce Quality
Management. However, the basic criteria for TQM
are similar on both sides of the Atlantic. This paper
will address the principles of TQM, International
Standards, and Review of International
Organisation Guidelines. Competence, Safety,
Decision Making, Quality, Reliability, Precision,
Accuracy, Contracting, Continuous Education,
Traceability, Validation & Interpretation of Results
all are part of any TQM programme. It is in the
interest of Patients, Society, Health providers,
Insurance Companies and Governments that
Medical Laboratories performance is of High
Standards of Professional and Technical
Competence, due to the followings:
Diagnosis, Prognosis and Treatment of various
diseases are frequently based on the results and
interpretations of Laboratory Tests.
Patients and Clinicians may not have sufficient
technical knowledge to determine whether a
laboratory operates at satisfactory level.
In many cases patients and/or clinicians have no
choice of laboratory.
Laboratory Tests are expensive and they are
expected to provide valid information.
It is of the interest of competent laboratories to
verify their competence through a process of
inspection.
TQM Process should include all laboratories and
in-vitro diagnostic activities including physician
office laboratories and point-of-care testing. TQM
should include regular inspection of:
1. Premises & other Facilities
2. Qualification of Lab Directors.
3. Qualification of Technical Staff.
4. Equipment.
5. Organisation & Administration.
6. Ethics.
7. Quality Policy.
TQM may be achieved by implementing ISO
standards of which 15189 – 2007 is the more recent
ISO dedicated for health laboratories. ISO 15189
addresses various aspects of Medical Laboratory
Practice which include:
1. Scope of the standard.
2. Normative references.
3. Terms and definitions.
4. Management requirement.

Beyond Means and SDS: Recommended Statistics for Knowledge Extraction from
Accumulated Pathology Data and Your Practice Experience
T F Hartley
Quality Manager, Pathology Services, Royal Hobart Hospital, Hobart, Tasmania, Austalia.. Email:
[email protected]
Objective : Clinical Biochemists have been
largely focussed on parametric statistical tests such
as means, standard deviations, coefficients of
variation, linear regression and correlation
coefficients. These tests are suited only to
parametric data which conform to the criterion that
the data analysed have been drawn from a notional
‘larger’ parent dataset that when plotted as a
57
histogram conforms to the ‘Normal Error Curve’.
In this paper the focus is on those statistical tests
which can be used on datasets upon which we have
no way of confirming that they are part of a “
‘larger’ parent ‘Normal Error Curve’ “. This is
particularly true of datasets from diseased patient
populations. Such datasets are more probably
skewed due to disproportionate mixing of data
from patients with ‘mild’, ‘moderate’ and ‘severe’.
Rather than risk applying invalid parametric
statistical tests to such datasets and thereby being
led into making misleading conclusions, the
recommendation of this paper is that more use is
made of non-parametric statistical tests. By going
down this non-parametric path we can enter the
new field of network analysis – the foundation of
‘knowledge mining’ – and discover new and
unexpected interdependences in our datasets.
Methods: Wherever possible either Excel or web
based calculators have been used to illustrate
performance and the advantages. Non-mainstream

your point of view, local or National. The

suggests that the consensus agreement should be

Network analysis of data from two cohorts of
medical inpatients – one before the changeover
from a Vitros 950 to an Abbott Architect and one
after revealed the following ‘rules’ based on the
assumption that the clinicians did change over to
the new reference intervals :
They would form the impression that there were
more low and fewer high Na and bicarbonate
results.
77% of patients with high K’s would also have
high ureas.
Only 55% of patients would have normal ureas
and K’s.
59% of patients would have low K’s and normal
ureas.
33% of patients with normal creatinines would
have high ureas.
Conclusion: Now is an opportune time to expand
our use of statistics in the clinical laboratory. We
have particularly stable analytical platforms so we
should spend more time on the objective
examination of the very large amounts of data these
systems produce. Within these datasets is a rich
resource of knowledge that can only be appreciated
after the application of robust and multiparameter
statistical tests that go beyond our usual practice.

Web Based Education and Training in Clinical Laboratory Services
Dr. Uday Donde
Director, UXL Advisor, Mumbai
Web based education, a powerful tool in the
education system, can help in imparting defined
knowledge, conducting assessment regarding
knowledge absorbed in terms of feedback and
examination, and developing skills through
animation. A simple platform to log on through a
personal computer having internet connectivity,
and registration of the user giving his specific
requirements is imperative. Specific identification
or password is given by the service provider to
begin the process of imparting education. Several
options are offered and a variety of software is
available. A report card or performance rating can
be generated to strengthen the student’s efforts.
As the student progresses, difficult level of the
examination can be increased, in order to create
further interest and increase knowledge. The
advantage of web based education is that a student
can learn what he wants, even from home, at his
own pace, whenever he wishes. (The “whatever,
whenever, wherever, however” concept). It is
advisable to supplement web based education with
on bench or in-field training in the field of clinical
laboratory services. This can best be achieved by
using animation / computer simulation which
should be corroborated with actual practical work
by providing self generated standard operating
procedures. This computer aided comprehensive
teaching – learning system can be employed to
any profession teaching, clinical laboratory
services, entrepreneurship etc. Besides web based
education in clinical biochemistry web based
awareness on regulatory bodies governing the
discipline of clinical biochemistry can also be
achieved. Salient information regarding the nature
of governance / regulation can be communicated
by providing links. The examples of such bodies
are IS / ISO, Government Ministries per se, FDA,
ICMR, MCI, NABL, Pollution Control Board, etc.
A handful of IT companies have shown interest in
developing this field for training clinical
biochemistry professional using virtual classroom
and e- learning methods. This would add value to
the academic and applied components of this
discipline. An exposure to this concept will be

Lean - Sigma Metrics Protocol of Total Quality Management in a
New Laboratory Set-up
Barnali Das
Kokilaben Dhirubhai Ambani Hospital & Medical Research Institute, Mumbai.
Objective: We aimed for Lean-Total Quality
Management (TQM) for setting up the
Biochemistry & Immunology laboratory for a 725
bedded new tertiary care hospital in Mumbai.
Methods: Components of TQM include all
divisions of the organization, namely, laboratory
operations,
information
management,
documentation and record maintenance, materials
59
and purchase, customer care, safety etc. During
the initial phase, we validated all the techniques
and new tests by verifying reference intervals,
analytical accuracy and precision, inter-assay and
intra-assay variations, analytical sensitivity,
linearity and reportable range.
Results: We take the example of alkaline
phosphatase (ALP) processed during start-up
phase of our laboratory to enumerate the above
validation steps. Reference range obtained for ALP
was 42.2 - 108.8 IU/L, which is within the
manufacturer’s reference range (30 - 120 IU/L).
Comparison of analytical accuracy between two
laboratories gave, y = 0.98x + 4.93, with r2 = 0.99,
establishing a high degree of linear correlation,
validating our laboratory procedures. Precision
verification from 15 replicates gave a coefficient
of variation (C.V.) of 1.04%, comparable with the
manufacturer’s claim. Intra- assay variations were
also within acceptable range (C.V. = 1.54%). 20
blanks were all within the stated blank value,
implying analytical sensitivity. Analytical
measurement range (AMR) was verified as
different levels of control sera were comparable
with the manufacturer’s claim, with C.V. 1.26%
and 0.69%, for level I and level II, respectively.
The standardized test showed good linearity with
different dilutions; recovery too was within an
acceptable limit (90-110%), with y = 0.99x – 2.81
and r2 = 0.99 between expected and observed
values.
Conclusion: We designed the entire loop of testing
process, including pre-analytical, analytical &
post-analytical phases according to the lean
principle through pneumatic system and sigma
metrics through DMAIC principle, i.e., Define,
Measure, Analyze, Improve and Control. This and
validation eliminates error in test results which is
important from the view point of both patients, as
well as of professional and regulatory bodies in
the health care domain.

Laboratory Management of the Metabolic Syndrome
Sridevi Devaraj
Professor, Pathology, Director, Special Chemistry and Toxicology, University of California Davis
Medical Center, Sacramento, California, USA; [email protected]
The metabolic syndrome afflicts approximately 1
in 4 American adults and is prevalent in many industrialized countries. Furthermore, the prevalence of the metabolic syndrome is on the increase
in Asian Indians. The metabolic syndrome confers at least a 2 fold risk of cardiovascular disease
and at least 5 fold increased risk for subsequent
diabetes. The features of the metabolic syndrome
include abdominal obesity, an atherogenic
dyslipidemia manifesting as elevated levels of triglycerides, low levels of HDL-C, and a preponderance of small dense LDL particles. Other features
include raised blood pressure, insulin resistance
and/or glucose tolerance, and associated increased
60
inflammation. The laboratory plays a critical role
in the diagnosis of the metabolic syndrome since
of the 5 features, 3 are laboratory based, including
triglycerides e”150mg/dL (1.7mmol/L), HDL-C
levels <40 mg/dL (1.1mmol/L) and 50 mg/dL
(1.3mmol/L) ( in men and women respectively)
and fasting plasma glucose e”100mg/dL (5.6mmol/
L) . In addition, it is not uncommon for patients
with metabolic syndrome to have non-alcoholic
steatosis hepatitis (NASH), generally diagnosed
by an increased in transaminases with ALT/AST
ratio >1 and sonographic evidence of fat accumulation in the liver. Also, patients with the metabolic syndrome can have hyperuricemia and
microalbuminuria. With regards to the atherogenic
dyslipidemia since the laboratory reports in a standardized fashion triglycerides, HDL and LDL cholesterol, it is also incumbent on the clinical laboratory to report the non-HDL-C which embraces
all the atherogenic ApoB carrying particles. It is
simply obtained by subtracting HDL cholesterol
from the total cholesterol. The non-HDL-C is especially important in patients with triglycerides
e”200mg/dL (2.25mmol/L) and the goal for nonHDL-C is the LDL goal plus 30mg/dL (0.77mmol/
L). Thus, in a patients with diabetes and metabolic syndrome, a LDL-C goal would be <100mg/
dL (2.6mmol/L) and non-HDL-C would be
<130mg/dL (3.3mmol/L). Other abnormalities
that have been reported in the metabolic syndrome
include elevated levels of remnant and remnant
like particles and small dense LDL. Also, patients
with the metabolic syndrome have elevated levels of ApoB, which is a better predictor of outcomes in statin trials than LDL-C.
Microalbuminuria is also relatively easily measured in the clinical laboratory and indeed can be
done on a spot urine sample, expressing it as albumin/creatinine ratio. Microalbuminuria defined
as between 30 to 300 ug/mg of creatinine would
also encourage the clinician to better manage the
patient especially with regards to hypertension and
abnormal glucose tolerance. C-reactive protein
(CRP) levels have been shown to predict cardiovascular events when measured by the high sensitivity (hs) assay and in fact are elevated in patients
with the metabolic syndrome and appears to confirm greater CVD risk . A hsCRP level in patients
with the metabolic syndrome between 3-10 mg/L
could inform the clinician to better target the
prothrombotic/proinflammatory status of the patient with therapeutic lifestyle changes and pharmacotherapy. Another very important adipokine
that has great relevance to the metabolic syndrome
is decreased levels of adiponectin. Lastly, whilst,
some measure of insulin sensitivity can be obtained
by using the homeostatic model (HOMA-IR), insulin assays are not standardized and thus any recommendation for reporting HOMA or QUICKI
measures of insulin resistance requires better standardization for clinical diagnosis. Other circulating biomarkers such interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), leptin, PAI1 retinol binding protein-4, may be relevant in
metabolic syndrome but belong to the research
arena presently.

Thyrotropin Secreting Pituitary Adenomas (TSHoma)
V.Parameswaran, G.Stilwell and J.Burgess
Diabetes and Endocrinology Services, Royal Hobart Hospital, Tasmania, Australia
Thyrotropin (TSH) secreting tumours of the
pituitary are uncommon and account for <1% of
all pituitary tumours. Although, TSHoma are a rare
cause of hyperthyroidism, it should still be ruled
out in the diagnosis of hyperthyroid patients. TSH
secreting tumours are slow growing and
consequently establishing a positive diagnosis may
take several years. Compared to males, females
have a slightly higher rate (55%) of these tumours
Laboratory results for thyroid function can be
variable from normal to very high results.
Radiological evaluation is required and exclusion
of other biochemical abnormalities is critical in
establishing a positive diagnosis of TSHoma. The
steps involved in differential diagnosis will be
presented and discussed using a clinical case.

Monogenic Disease in Endocrinology
Tjin-Shing Jap
Section of Biochemistry, Taipei Veterans General Hospital, Taiwan, ROC 112
Monogenic disease is relatively quite common in
the field of Diabetology and Endocrinology.
Maturity-onset diabetes of the young (MODY) is
responsible for only 2-5 % of type 2 diabetes in
western population. It is also an autosomal
dominant disorder with a typical age of onset of
less than 25. Recently, we have identified two
patients with MODY3 had missense mutations in
exon 3 of the HNF-1á gene (Y218C and R272H,
respectively) in a region of the protein that
corresponds to a predicted DNA binding domain.
Homozygous-trait hypercholesterolemia is due to
mutation of gene encoding LDL-receptor, may
cause severe xanthomatosis and early death by the
age of 30. We identified 5 missense of mutations
and one large deletion in LDLR gene, including
one novel mutation in Taiwan. Mutation of gene
encoding lipoprotein lipase may cause family
hypertriglyceridemia with clinical manifestations
of pancreatitis and early atherosclerosis. L252V
mutation is the most common in Taiwan. Complete
TBG deficiency may be misdiagnosed as a case
of clinical hypothyroidism. We have found two
cases with complete TBGD due to novel TBG gene
mutations (S52N and W280Y). Familial
hypocalciuria hypercalcemia is due to a mutation
of the gene encoding calcium sensing receptor. We
have reported a case with the long-standing benign
hypercalcemia due to R648X mutation of CaSR
gene. To our knowledge, it is the first case of FHH
reported with CaSR gene mutation in China and
Taiwan. We have identified the MEN1 gene
mutation of nine Han Chinese families with MEN1
living in Taiwan, including five novel mutations.
Recently we have also found a patient with CAH
due to a compound heterozygous mutations of
R362C and P409R in the P450c17 (17-??hydroxylase/ 17,20 Lyase) Gene. In recent years,
we have successfully identified several families
with clear single gene mutation causing

Obesity – A Global Epidemic
Dr. Nalini Ganesan
Professor, Department of Biochemistry, SRMC & RI, Sri Ramachandra University, Porur, Chennai – 116
The growing prevalence of obesity worldwide is
an increasing concern surrounding the rising rates
of type-2 diabetes, cardiovascular disease and
consequent health and financial implications for
the population. The United States has the highest
prevalence rates of obesity worldwide, now
exceeding 30 %. Moreover, the prevalence of
obesity is rising in developing countries. The
62
etiology of obesity is multifactorial and rapid rise
in prevalence of this epidemic throughout the world
has indicated that the environmental changes are
the major determinants modifying the individual
susceptibility to these environmental factors. The
root cause for obesity being energy imbalance and
is associated with significant morbidity and
mortality. The classical problems associated with
obesity range from mechanical such as
osteoarthritis and sleep apnea to metabolic
perturbations resulting in type 2 diabetes,
hyperlipidemia, hypertension and overall
increased cardiovascular risk. There is also an
increasing realization that obesity is associated
with higher risk for developing certain cancers.
This review addresses physiological and
neuromolecular mechanism regulating energy
balance by focusing on adipocyte metabolism,
adipocyte dysfunction, etiopathogenesis,
environmental and genetic determinants,
mitochondrial dysfunction and secondary
pathologies promoted by obesity. Greater insight
into mechanism behind this may improve our
understanding of how to prevent and best manage
this complex condition. We are planning to
produce our experimental evidence on the
biochemical and genetic aspect pertaining to
obesity.

The human brain has mystified people throughout history. Though it weighs a mere 1.5kg and is
small enough to hold in our hands, it is our body’s
most vital organ. It’s complex network of 100 billion or more nerve cells orchestrates every aspect
of our thoughts, perception and behavior. More
than anything else, our brain defines who we are.
Brain is remarkably plastic and continues to
change throughout life in accordance with our
experiences. Brain, behavior and environment are
all intricately linked in an interactive loop: changes
in the environment leads to changes in behavior
which lead to changes in the brain. Immune cells
which constitute the body’s biological defense
against infections and toxins have many things in
common with nerve cells. One of the most exciting findings in recent years is that neuroendocrine
system and immune system communicate through
common biochemical language. Cytokines released from cells of immune system inhibit gonadotropin releasing hormone (GnRH) release an
action similar to that of nitric oxide synthase
(NOS) inhibitor. Nitric oxide (NO), an ubiquitous signal molecule, plays a crucial role in a host
of biological systems including the brain as a neurotransmitter. Nitric oxide synthase (NOS) containing neurons occur in the hypothalamus where
the perikarya are located in paraventriculr and supraoptic nuclei their axons project to the neural
lobe of the pituitary gland , the structure that contain the largest quantity of NOS of any organ in
the body. When both NOS inhibitor and cytokine
were added together, both in vivo and in vitro incubation systems there was an additive suppressive effect on GnRH/ LH release. Our understanding of these complex interactions between the brain
and the immune system is revealing targets for
therapeutic intervention. For instance, possibility
of various vaccines that might arrest or slow the
progress of brain tumor growth or Alzheimer’s
disease and clinical trials of an immune therapy
for spinal cord injury are underway. (Supported

Background: Ethanol is a small molecule that has
a negative impact on human health and moderate
to heavy doses of alcohol have deleterious effects
and especially on brain and its different
compartments. Ethanol is also responsible for
degenerative changes in brain.
Methods: In the present study with Male Wistar
rat, we investigated the role of natural antioxidants
like grape polyphenols and Vit E in combating
the ROS balance in alcoholism for a dose of 4g /
Kg b.w/day of ethanol for a period of 12 weeks.
Results: Ethanol intoxication in brain upregulates
COX-2, iNOS levels and p38 MAPK pathways
as evidenced by immunohistochemical studies of
different sections of brain, and increases cell death
in different brain compartments as evidenced by
Caspase-3 and Caspase-8 expression and TUNEL
assay by Immunohistochemistry.
Conclusion: Grape polyphenols show protective
effect to ethanol induced brain damage by
regulating the inflammatory processes with the
alteration of the VEGF receptors (flk1 and flt1)
and VWF-VIII facilitating vasculogenesis. These
findings indicate that exposure to ethanol for a
higher dose induces brain damage triggering the
inflammatory processes and leads to neuronal
apoptosis.

cells with only collagen resulted monolayer

with human fibroblasts showed appearances of
activation in both the epithelial cells and
fibroblasts, suggesting the interactivity between
the two types of cells. Particularly, in RGK1 cells
grew with multiple cell layers (the layers), and
fibers and fibrous margin were found inside the
layers and in collagen site facing the layers.
Results by treatment of a matrix metalloproteinase
(MMP) inhibitor using Marimastat to the 3D
cultures showed disappearance of activation of
both the epithelial cells and fibroblasts or
dissociation of the interactivity.

The field of Biomarkers that can predict the course
of the cancer progression has been an important
area of intense research in recent times. Gene
expression profiling using gene microarrays has
been the choice of investigation for a high throughput analysis and identification of biomarkers. Our
group has been working with cancer and pre cancer tissues to identify novel biomarkers of prognostic value. We carried out microarray analysis
of glioma tumors of different grades using cDNA
microarray. Data analysis identified several differentially regulated genes between normal brain
tissue and various grades of gliomas. Further,
several novel genes are differentially expressed
between grades II/III astrocytoma (low grade) and
glioblastoma multiforme (GBM; grade IV). By
real time PCR analysis we found differential regulation of several genes in the Notch signalling pathway such as ASCL1 (Hash 1), Hes1, Hes6 and
Delta1. In addition, differential expression of many
other already known and novel genes in gliomas
has been identified. Real time PCR validations of
some selected genes are in agreement with the array results. Genes that show differential regulation are in the categories of transcription factors,
signalling intermediates and secreted factors. In
addition, we found expression of few genes correlating with prognosis of the GBM patients. Our
data could form a basis for building diagnostic/
prognostic gene signatures in glioma progression
and novel therapeutic targets.

In the Asia-pacific region incidence of cervical
cancer cervix is high second to breast cancer.
Prognosis of invasive carcinoma is based mainly
on subjective clinical staging. Abnormalities in
cytokine production have been found in invasive
cervical carcinomas. A correlation between
cytokine expression and different clinical
parameters such as tumor and lymph node status,
HPV expression and disease free survival were
evaluated. Human Papilloma Virus (HPV) is the
major cause. A total of 43 cervical biopsies
collected from sequentially enrolled patients were
analyzed by DNA amplification and sequenced
to determine the HPV genotype. Samples with
multiple infections were resolved by multiplex
PCR combined with array primer extension
(APEX) Nine different HPVs mainly 16 and 18
were detected. Multiple HPV infections correlated
prominently with lack of treatment response
compared with single type infection that again
reiterates the risk of treatment failure. Cytokine

Natural Products as Potential Treatments for the Human Metabolic Syndrome
Lindsay Brown
School of Biomedical Sciences, The University of Queensland, Australia
Metabolic syndrome is the clustering of abdominal obesity, insulin resistance, dyslipidaemia,
hyperglycaemia, a prothrombotic state and hypertension that increases the risk of cardiovascular
disease and fatty liver in humans. Diets rich in
carbohydrates and saturated fats contribute to the
signs of the metabolic syndrome. Animal models
that mimic the range of pathophysiological
changes seen in humans diagnosed with metabolic
syndrome are necessary to understand the initiation and progression of metabolic syndrome and
the development of new treatments. The metabolic
changes and the structure and function of the heart
and liver were characterised in young adult male
Wistar rats fed a high carbohydrate/high fat diet
for 16 weeks. These rats developed many of the
chronic signs of the metabolic syndrome in humans including hypertension, impaired glucose
tolerance, increased oxidative stress, plasma lipid
abnormalities, excess deposition of abdominal visceral fat, increased waist circumference, ventricular dilatation with hypertrophy and decreased contractile function, impaired conduction, increased
inflammatory cell infiltration into the myocardium
and liver resulting in fibrosis, an increased stiffness of the heart, endothelial dysfunction as a decreased response to acetylcholine and increased
plasma concentrations of liver enzymes. Further,
oral chronic treatment with curcumin or rutin attenuated or reversed these structural and functional
changes in the heart and liver. Thus, this dietaryinduced model of the metabolic syndrome in rats
may provide a realistic and useful experimental
tool to evaluate the development of symptoms and
their reversal by potential treatments such as natural products.

Agartala 799 006, Tripura, e-mail: [email protected]
Background: A number of factors are linked with
non-alcoholic fatty liver diseases (NAFLD), a
condition that ranges from clinically benign fatty
liver to its more severe form, non alcoholic
steatohepatitis (NASH).
Objective: To evaluate the role of anthropometric
profile, lipid profile, insulin resistance data, pro-
inflammatory and anti-inflammatory cytokines in
NAFLD patients.
Methods: A complete clinical history, including
body mass index and waist-to-hip ratio were
obtained in 105 NAFLD patients (89 male and 16
female) and 77 normal subjects (45 male and 32
female). Blood collected after over night fast was
67
used for the determination of biochemical
parameters including glucose level, insulin level,
lipid profile and cytokine estimations. Insulin
resistance was calculated by the homeostasis
model.
Results: Predisposing factors were diabetes
mellitus (35%), overweight (56%) and
hyperlipidemia (44%). Insulin resistance was
confirmed in 70% NAFLD patients, and 42%
fulfilled minimum criteria for insulin resistance
syndrome. NAFLD patients showed elevated
levels of TNF-a and TGF-b1, while IL-4 level
decreased significantly compared to normal
subjects.
Conclusion: Insulin resistance and cytokines may
be responsible for fibrogenic processes in NAFLD.

Multiple sclerosis (MS) is a disease that affects
the central nervous system (CNS) with significant
human and community costs. Although the precise trigger(s) remain elusive, the ultimate end
point of the disease is the destruction of nerve
axons and myelin, two key cellular components
of the CNS involved in the conduction of nerve
impulses. As a consequence patients with MS suffer from numerous neurological problems. At
present, there is no cure for this severe
68
neurodegenerative condition. Although, immune
therapy is beneficial to a proportion of patients,
others do not respond to any currently available
therapies. A rational approach to the treatment and
cure of autoimmune diseases such as MS requires
incorporation of three fundamental processes: suppression of the inflammatory response, regeneration of the target cells or tissues and restoration of
self tolerance, whereby damaging white immune
cells can be purged or silence. Current clinical
practice at best addresses the first problem but

“Inflammation” is the process by which the body
responds to injury or an infection. Laboratory
evidence and findings from clinical and population studies suggest that inflammation is important in atherosclerosis. This is the process in which
fatty deposits build up in the inner lining of arteries. C-reactive protein (CRP) is one of the acute
phase proteins that increase during systemic inflammation. It’s been suggested that testing CRP
levels in the blood may be an additional way to
assess cardiovascular disease risk. A more sensitive CRP test, called a highly sensitive C-reactive protein (hs-CRP) assay, is available to determine heart disease risk. Number of studies have
examined whether hs-CRP can predict recurrent
cardiovascular disease, stroke and death in different settings. High levels of hs-CRP consistently
predict recurrent coronary events in patients with
unstable angina and acute myocardial infarction
(heart attack). Higher hs-CRP levels also are associated with lower survival rates in these
patients. Many studies have suggested that after
adjusting for other prognostic factors, hs-CRP is
useful as a risk predictor. Studies also suggest that
higher levels of hs-CRP may increase the risk that
an artery will reclose after it’s been opened by balloon angioplasty. High levels of hs-CRP in the
blood also seem to predict prognosis and recurrent events in patients with stroke or peripheral
arterial disease. Scientific studies have found that
the higher the hs-CRP levels, the higher the risk
of having a heart attack. In fact, the risk for heart
attack in people in the upper third of hs-CRP levels has been determined to be twice that of those
whose hs-CRP level is in the lower third. The true
independent association between hs-CRP and new
cardiovascular events hasn’t yet been established.

Pro-oxidant Activity of Artemisinin Causes an Apoptosis Like Death in
Leishmania parasites

Bose Road, Kolkata Email: [email protected]
Leishmaniasis is a vector-borne disease caused by
the obligatory protozoan parasite, Leishmania sp.,
affecting over 12 million people worldwide. In
India, the emerging refractoriness to conventional
70
antimonial treatment has highlighted the need for
newer antileishmanial compounds. Artemisinin, an
established anti-malarial drug, was found to be an
effective anti-leishmanial drug, the IC 50 in
amastigotes being 22 µM. This leishmanicidal
activity was mediated by an increased generation
of reactive oxygen species, coupled with depletion
of non protein thiols; furthermore, the addition of
N-acetyl cytseine increased the IC 50 of
Artemisinin, confirming the critical role of free
radicals. This oxidative insult upon the parasite
triggered an enhanced influx of Ca++, translating
into mitochondrial membrane depolarization,
increased
annexin-V
positivity,
deoxynucleotidyltransferase-mediated dUTP nick
end labeling, finally leading to an increased sub
G0/G1 population, features of apoptosis. However,
this programmed cell death was not accompanied
by enhancement of caspase activity suggesting
non-involvement of caspases. Additionally, in vivo
experiments in L. donovani infected mice
confirmed the efficacy of Artemisinin (10 and 25
mg/kg b.w.) which was accompanied by up
regulation of intracellular levels of Th1 cytokines,
IFN-ã and IL-2 in splenocytes. Taken together,
Artemisinin is an effective leishmanicidal agent
that causes an apoptosis like death in parasites,
meriting future pharmacological studies.

Medical Sciences, Sevagram, Maharashtra -442102 (e-mail: [email protected])
The rapid progress in Filarial Genome Project has
led to the identification of variety of novel filarial
genes or recombinant proteins of Brugia malayi
or Wuchereria bancrofti as promising vaccine
candidates. These include abundantly expressed
molecules viz., abundant larval transcripts (ALT)
and venom allergen homologue (VAH),
antioxidant enzymes viz., glutathione-Stransferase (GST), superoxide dismutase (SOD),
thioredoxin peroxidise (TPX) and other crucial
enzymes like transglutaminase (TGA).
Vaccination with B. malayi enzymes SOD, TGA,
TPX induced low to moderate (30 to 46% )
cytotoxicity against microfilaria (mf) or L3 larvae
or protection against challenge B. malayi infection
in jird model. In contrast Bm ALT-2 or Wb GST
induced 69% and 61% protection respectively
against B. malayi challenge infection in jird
model. When compared to these single antigen
vaccines, fusion proteins or multiple antigen
vaccinations generally offered better protection.
Bm ALT-2 in combination with Wb GST, Bm TPX
and Bm VAH enhanced the protection to 71%, 74%
and 78% respectively. Although DNA vaccines
have several advantages over conventional
vaccines, filarial DNA vaccines particularly in
single plasmid vaccination were often not adequate
in antibody production and protection. DNA
vaccine of Bm-tga could not induce much
protection against challenge infection in mouse
model. DNA vaccines of Bm-vah, Bm alt-2 and
Bm-tpx induced only 50.2%, 55.8% and 37%
cytotoxicity respectively against B.malayi mf. In
contrast the cocktail vaccination of Bm-alt-2 in
combination with Bm-vah and Bm-tpx induced up
to 63% and 78% cytotoxicity respectively against
mf or L3 larvae. Taken together these studies
favour the use of multiple antigen vaccination with
combination of two or more antigens / genes as an
effective vaccine development strategy in

Bilirubin from Toxic Metabolite to an Antioxidant: Mechanisms
S. Adhikari
Radiation and Photochemistry Division, Chemistry Group, Bhabha Atomic Research Centre
Mumbai 400 085, India Email: [email protected]
Bilirubun has two extreme roles to play in physiology. In one side it is a toxic metabolite while at
micromolar concentration it is better antioxidant
than???tocopherol and thiols. It is a toxin because
it’s association with neonatal jaundice, possibly
leading to irreversible brain damage due to neurotoxicity. On the other hand, bilirubin can act as
an important cytoprotector of tissues that are
poorly equipped with antioxidant defence systems,
including myocardium and nervous tissue. Bilirubin can suppress oxidation of lysosomes at oxygen concentrations that are physiologically relevant. The antioxidant-prooxidant mechanism of
bilirubin will be discussed in the present paper.
Our study demonstrates that hydroxyl and
glutathiyl radicals abstract hydrogen atom from
bilirubin and forms a carbon-centered radical. The
bilirubin radical thus produced, decays with first
order rate and decays faster in presence of oxygen. At a later stage bilirubin forms a peroxyl radical in presence of oxygen. This is the first direct
observation of the bilirubin peroxyl radical formation which may answer the situation of low
protection of lipid peroxidation in a condition of
higher than the physiologically relevant oxygen
concentration. Bilirubin induced toxicity may also
arise from the aforesaid peroxyl radical formation.
Linoleic acid peroxyl radical also reacts with bilirubin via hydrogen abstraction. In the case of NO2.
radical reaction, bilirubin produces radical cation
via single electron transfer reaction. These results
show that in the oxidation of bilirubin both hydrogen atom transfer and single electron transfer are
possible depending on the nature of the oxidizing
radical. HPLC analysis of the products also supports our mechanism. Another aspect of bilirubin
that will be discussed is the free radical induced
recyclization. Through its antioxidant action, bilirubin produces biliverdin as a major product. The
conversion of biliverdin to bilirubin is a physiological enzymatic process. Results from our laboratory shows that under certain condition, this recycling process from bilirubin to biliverdin and again
bilirubin back can also occur through a free radical pathway.

New Perspectives on the Clinical Importance and Applications of Vitamin D Testing
H.A Morris
Hanson Institute, SA Pathology, Adelaide South Australia 5000
The vitamin D system plays a primary role in the
maintenance of calcium, and phosphate
homeostasis. Recently it has been identified as
exerting a wider range of biological activities
including regulation of cellular differentiation and
proliferation and therefore it has implications for
cancer, the immune system, and reproduction. The
endocrine action of vitamin D acts through the
72
renal metabolism of vitamin D, producing 1,25
dihydroxyvitamin D (1,25D) for the circulation.
The major organ responding to plasma 1,25D is
the small intestine where it controls intestinal
absorption of calcium and phosphate. 1,25D is also
synthesised in a wide range of tissues including
bone cells where it is believed to exert an autocrine
or paracrine activity. Vitamin D insufficiency in
the elderly has clearly demonstrated an increased
risk of hip fracture. A major question for the
clinical laboratory is what is the vitamin D
requirement for a healthy skeleton? Measurement
of vitamin D status in apparently healthy
individuals merely assesses their level of sunlight
exposure and does not indicate vitamin D
requirements. Current evidence from a wide range
of sources including clinical data indicate that
levels of serum 25-hydroxyvitamin D (25D) below
20 nmol/L are clearly deficient and give rise to
osteomalacia, a bone mineralisation defect.
However evidence is accumulating to suggest that
25D levels between 20 and 80 nmol/L indicate a
depleted vitamin D status causing bone loss and
increasing the risk of fracture as well as increasing
the risk of colon cancer and infection. These
findings suggest that the lower level of the
desirable limit for vitamin D should be
significantly higher than currently used by many
laboratories

We evaluated the effect of lycopene a dietary
carotenoid on human lymphocytes exposed to γradiation. Cells were exposed to ã-radiation at a
dose of 4 Gy in the presence and absence of
lycopene pretreatment. Lymphocytes when
exposed to ã-radiation at a dose of 4 Gy resulted
in DNA damage, delay in cell cycle, DNA
fragmentation, up-regulation of caspases-3
caspases 9, Bax, cytochrome-c and MAPK
signaling pathways and down regulation of Bcl2, DNA repair enzymes (HOGG1 and XRCC1)
and reduction in the mitochondrial
transmembrane potential when compared to
normal control. When these cells were pretreated
with lycopene and then administered radiation all
these effects were reversed. Suggesting that
lycopene offers protection to normal cells when
exposed to radiation. We also wanted to study
whether lycopene can offer protection to cancer
cells when exposed to radiation. In this context
we used lymphoblastoid TK-6 cells in culture.
When TK-6 cells was pretreated with lycopene and
then administered ã-radiation, we found that the
intensity of damage to cancer cells were much
higher when the same amount of radiation was give
to control TK-6 cells.
Thus the study shows that lycopene while
protecting normal cells acts in combination with
ã-radiation to destroy more amount of cancer cells
than in control TK-6 cells given radiation.

recently we have shown that it perturbs the
glycalyx, which decorates the luminal surface,
resulting in endothelial dysfunction. Many of the
effects such as impairment of vasoreacitvity,
stimulation of Tissue Factor, MMP-9 and increase
uptake of oxidized-LDL have been confirmed invivo.
Results: In this presentation, I will focus on the
role of CRP in promoting atherothrombosis by
discussing its effects on endothelial cells,
endothelial progenitor cells, monocytemacrophages, and smooth muscle cells. The most
abundant data relates to its effects on endothelial
cells; CRP inhibits eNOS via uncoupling,
stimulates monocyte adhesion, PAI-1, IL-8, and
Conclusions: CRP is clearly a risk marker for
cardiovascular disease and is recommended for use
in primary prevention. In addition, CRP appears
also to contribute to atherogenesis. However,
further in-vivo research is needed to establish its
role in atherothrombosis. This will lead to novel
therapeutic strategies.

The Clinically Effective Use of Available Cardiac Biomarkers.
Ray U
Department of Pathology, Royal Hobart Hospital, University of Tasmania, Australia
Heart is a non-stop pump supplying nutrition and
oxygen to the cells of the body including its own
through coronary circulations. Coronary
circulation has its unique networks. Any
derangement in its own supply would cause
cellular anoxia, trigger cellular leakage and
jeopardise its pumping function. Acute coronary
syndrome (ACS) is diagnosed by elevated cardiac
markers, ECG changes and acute chest pain/
heaviness in the chest. Although currently there
is a strong suggestion to use only the 99 th
percentile changes in serial cardiac Troponin in
the diagnosis of ACS, judicious use of multiple
cardiac markers (CK-MB, Myoglobin and cTroponin) could be useful in the early diagnosis
74
of ACS so that timely institution of either
thrombolytic or interventional therapy could be
done to save this hard working indispensable
pump. Any increase in the intraventricular pressure
or volume or both stimulate cardiac myocytes
which release B-type natriuretic peptide (BNP)
detectable immediately in the circulation. It is quite
probable that acute ischemic event alters heart
pump and brings forth a change in intraventricular
pressure and volume. Thus there should be BNP
release in the circulation. Serial assay of BNP along
with CK-MB, myoglobin and c-Troponin could be
thus used not only to diagnose ACS but also to
stratify risk associated with it and further prognosis
following therapy.

Mycobacterial ES-31 Serine Protease of Interest in Diagnosis of Tuberculosis and
HIV-TB Co-infection and with Potential as Drug Target

India, E-mail: [email protected]
Tuberculosis (TB) remains a major threat to public health worldwide and has been declared as
global emergency by WHO in 1993. According
to the World Health Organization (WHO, 2009),
9 million new TB cases including 4 million smear
positive cases with 15% HIV- Positivity have been
reported in 2007. Seroreactivity of the purified
excretory secretory (ES) antigens ES-31, ES-43,
ES-41 and ES-6 have been assessed in pulmonary tuberculosis (fresh, relapse, chronic and latent), extrapulmonary tuberculosis and in HIV-TB
co-infection. Analysis of immune response to
these purified antigens by indirect and sandwich
ELISA using highly sensitive and semiquantitative
Penicillinase enzyme immuno assay, showed ES31 antigen as having good diagnostic potential in
pulmonary tuberculosis and in certain groups of
extrapulmonary tuberculosis in particular tuberculous lymphadenopathy, tuberculous meningitis,
whereas ES-41 was found to be more seroreactive
in abdominal and bone & joint tuberculosis. ES43 antigen was primarily recognized by serum
antibodies in relapse cases while ES-6 was useful
in contacts. Antigen assay was found to be more
sensitive than antibody based assay for detecting
tuberculosis
with
HIV
coinfection.
Immunomonitoring for presence of antigen in TB
patients under ATT, showed that ES-31 antigen
assay was useful in determining the effectiveness
of therapy and patient’s compliance. User friendly
Peroxidase ELISA has been standardized for detection of circulating mycobacterial ES-31 serine
protease (Free antigen and Immune complexed
antigen) with 70-75% sensitivity and 90% specificity and with a limit of detection of antigen at 1
ng/2?l (0.5 ?g / ml serum). Further study revealed
that ES-31 antigen is a zinc containing serine protease. Serine protease inhibitors such as pefabloc,
3, 4 dichloroisocoumarin, phenyl methyl sulphonyl
fluoride (PMSF) and metalloprotease inhibitors
such as ethylene diamine tetracetic acid (EDTA)
and 1, 10 phenanthroline inhibited 65 - 92 % of
serine protease activity in vitro. Isoniazid showed
95% inhibition on mycobacterial ES-31 serine protease. These inhibitors also showed decreased bacterial growth in axenic culture and inhibition is
further confirmed by decreased amount of ES-31
serine protease in culture filtrate. In human macrophage culture, highly inhibitory pefabloc, 1,10
phenanthroline and isoniazid inhibited infectivity
of virulent as well as avirulent M. tuberculosis
bacilli to macrophages. The enhancement of bacterial growth in the presence of mycobacterial ES31 serine protease while inhibition in the presence
of anti ES-31 serine protease antibody was observed showing the importance of enzyme for entry and multiplication of bacilli. Immunofluorescence study using Fluorescence labelled anti ES31 antibody showed the presence of ES-31 serine
protease on mycobacterial cell surface.

Autoantibodies: Is it Possible to Predict Autoimmune Diseases?
Marcos López-Hoyos
Servicio Inmunología Hospital Universitario Marqués De Valdecilla, Santander, Spain.
A good biomarker should fulfill four
characteristics: sensitive, specific, detectable in
early disease and predictive of prognosis.
Autoantibodies are the most widely used
biomarkers in the diagnosis of autoimmune
diseases and, in some cases, in the prognosis
prediction. In the last years several prospective
studies have been published supporting their utility
in the prediction of an ongoing autoimmune
disease in healthy subjects, although they are still
few and large scale studies are needed. The
prediction of autoimmune disease is of special
utility since autoimmune diseases can be preceded
by a symptom-free phase that may last for many
years. In this scenario autoantibodies may have a
high positive predictive value for the disease onset,
severity and organ-specific complications,
especially in genetically prone individuals, in
whom an environmental trigger may switch on the
disease. One of the most active areas of work at
present in autoimmunity is the development of
autoantibodies profiles to identify those patients
at risk of developing an autoimmune disease. These
autoantibody profiles can be applied to the clinical
management of healthy population and high-risk
subjects. The session will review the recent
evidence on the predictive value of autoantibodies
and will underline the future lines in this field.

Cell-Cycle Synchronization in Antinuclear Antibodies Detection
Petraki Munujos Vinyoles
R&D Department. BioSystems, S.A. Barcelona, Spain
Anti-nuclear antibodies (ANA) are one of the most
common parameters analyzed in the autoimmunity laboratory, and the indirect immunofluorescence technique, the major screening method in
systemic autoimmune diseases. The identification
of the immunofluorescent staining patterns on
HEp2 cells is often difficult due to the complexity of the interpretation of the images observed.
In addition, the quality of the cell culture, the developing procedure and the conjugate, among others, are the key point for a correct determination.
These cell cultures must meet some requirements
to guarantee good results, among which the presence of cells in mitosis has become a differenctial
feature when judging the suitability of the HEp2
cell slides manufacturers. There are mainly two
reasons for which it is important a certain per76
centage of cells in mitosis: the existence of autoantibodies reacting with proteins that only express during the mitosis phases, and the fact that
some patterns are similar to such an extent that
the only distinctive feature to identify them is the
staining shown by the cells in mitosis. While in an
asynchronic culture, only up to 1-2% of cells are
found in M phase, a culture that has been synchronized in early S phase can display around 10-20%
of cells in mitosis. There are several possible approaches to achieve a certain percentage of synchronized cells in an in vitro cell culture. Basically, they can be divided in biological and chemical methods, and depending on the final use of the
synchronized culture, some methods can be more
appropriate than others.

Tissue Zinc Levels in Carcinoma
Dr. R.Selvakumar
Professor & Head, Dept Of Clinical Biochemistry, C.M.C. Hospital, Vellore - 632004
Email: [email protected]
Colon cancer is among the most common human
malignancies and remains a leading cause of
cancer related morbidity and mortality. The
transition from normal mucosa to adenoma and
its subsequent progression to carcinoma are events
that offer opportunities for preventive
interventions. The role of zinc in carcinoma
development has been the subject of debate and
reports of zinc values in the biological fluids from
cancer patients are often conflicting and
contradictory. Hence the mechanism by which
plasma zinc and tissue zinc decrease in various
cancerous tissues is still obscure. The disruption
of zinc homeostasis can play a significant role in
the development and progression of cancer. In
order to investigate the relevance of the tissue zinc
and zinc related enzymes such as CuZnSOD and
alkaline phosphatase activities in the development
of precancerous and cancerous process in the
colon, we have used well established colon cancer
model in the rat. Tissue zinc levels were analyzed
in the various parts of the G.I tract and other organs
of normal healthy rats. There was a gradual
decrease in tissue zinc concentration along the
various regions of the stomach from fundus, body
and antrum which was statistically significant. The
highest levels of tissue zinc were found in the
esophagus, testes and prostate. The DMH induced
precancerous and colon carcinoma model showed
that dysplasia and carcinoma were established
histologically in rats at four months and six months
respectively. These histological changes were
directly related to a significant decrease in plasma
zinc, tissue zinc, CuZnSOD and alkaline
phophatase activities when compared to controls
treated with saline. The mean % decrease in all
the 4 parameters was greater in the carcinoma
model as compared to the precancerous model.
Besides the significant decrease in tissue zinc and
zinc related enzymes in various parts of the G.I
77
tract (stomach and small intestine) in the
carcinoma model shows that transmural changes
along the wall of the G.I tract could be the cause
of the decrease. The above findings support the
view that decrease in tissue zinc and zinc related
enzymes are representative of biochemical
alterations in the colonic mucosa which may
reflect cellular changes that progressed to
dysplasia and frank malignancy. The high
incidence and mortality of colon cancer make
effective prevention an important public health
and economic issue. Suppression or reversal of
the carcinogenic process in the colon with nonpharmacologic or pharmacologic agent is an area
of considerable interest. Hence the role of the 3
agents such as Vitamin C, aspirin and zinc in DMH
induced precancerous and cancerous models in rat
were evaluated in this study. The results indicated
that co-administration with aspirin or vitamin C
in the precancerous and cancerous model
maintained normal histology in the colon in 88%
of rats along with a relatively lesser decrease in
colonic tissue zinc levels whereas plasma zinc and
zinc related enzymes showed no significant
changes. Co-administration with zinc in the
precancerous and carcinoma group prevented
histological changes in the colon in all rats. The
colon maintained normal histology with no
significant changes in the biochemical parameters
i.e plasma zinc, tissue zinc and zinc related
enzymes as compared to controls. In our study on
stomach cancer and colon cancer in humans, a
significant decrease in tissue zinc in the cancerous
tissue was observed as compared to their paired
non-cancerous tissue of the same individual. In
patients with prostate cancer, we observed a
significant decrease in mean tissue zinc levels in
prostate cancer and in BPH as compared to normal
prostate from autopsy cases. Plasma zinc was
significantly decreased in prostate cancer as
compared to BPH and normal subjects. Urine zinc
/creatinine ratio was significantly increased in
prostate cancer as compared to BPH and normal
subjects.

Prenatal Screening for Chromosomal Disorders
Päivi Laitinen
Docent, Laboratory, Oulu University Hospital, Oulu, Finland
Prenatal diagnosis has an important role in the
management of pregnancies. In Western countries
the current trend of family planning is toward
smaller families and the average age women have
babies is increasing, which increases the risk for
fetal chromosomal disorders. Today women are
also more aware of the frequency and the
importance of congenital disorders. Modern
trisomy screening combines the first trimester
serum biochemical test with the thickness of the
fetal nuchal translucency. The combined test
improves the detection rate and reduces the false
78
positive rate, compared to either biochemical or
nuchal translucency testing used alone. Pregnant
women and health care providers in Finland prefer
early testing in order to gain more time for
consideration of further procedures in case of a
positive test result. The second important issue is
to find a balance between testing sensitivity and
invasive procedures. Down’s syndrome is the
primary reason for families to seek prenatal
counseling. Effective first trimester screening for
chromosomal abnormalities is provided by a
combination of maternal age, gestational age, fetal
nuchal translucency measurement and maternal
serum free B-hCG and PAPP-A concentrations.
In Northern Finland we started prenatal screening
program in 2002. In 2002-2007 we have analyzed
25 000 samples for biochemical markers. In
17 000 cases also nuchal translucency was
measured. The screen positive rate of the combined
screening was 4.5% and the detection rate for
Down syndrome was 84%. These results are in
accordance with the published results in other
screening centers.

Routine Screening of Newborns for Metabolic Disorders using Tandem Mass
Spectrometry
Rohit Cariappa
Chief Scientist, NeoGen Labs, Bangalore
Routine high throughput newborn screening for
metabolic disorders using Tandem Mass
Spectrometry (MS/MS) has been carried out in
developed countries for the past 15 years. Based
on the screening of over 4 million babies the
process has been optimized such that several
hundred samples per day can be analyzed without
the direct interaction of a metabolic expert in every
sample. The false positive rate for the detection
of over 45 metabolic disorders using licensed
software and interpretation algorithms is currently
less than 0.1% and the false negative rate is 0%.
Tandem Mass Spectrometry (MS/MS) technology
routinely screens for several classes of metabolic
disorders like fatty acid oxidation, amino acid and
organic acid disorders all from one small disc of
dried blood in a single analytic run. Because it is
much more sensitive, specific, reliable and
comprehensive than traditional assays it has found
widespread use in newborn screening programs
around the world. It has replaced most of the oneanalysis, one-metabolite, one-disease classic
screening techniques with one-analysis, multiplemetabolites, many-diseases approach. The
conventional approach of first describing a disease
and then noting which metabolites are increased
has given way to the reverse approach which first
measures a large number of metabolically
important analytes from a routine blood sample
collected during the newborn period. Then, if
certain individual analytes or multi-analytes and
analyte ratios are elevated or decreased outside of
normal ranges, the software pinpoints the exact
metabolic disorder. The distinct benefit of early
routine screening is that the pre-symptomatic
detection of a metabolic disorder allows for
corresponding early treatment which increases the
likelihood of excellent outcomes. Treatment for
the different classes of metabolic disorders can be
in the form of dietary modification or special
formulas, vitamin or L-carnitine supplementation
or simple avoidance of certain foods, drugs and
chemicals for the affected individuals. The
undiagnosed or untreated outcome for those
afflicted with a metabolic disorder is very severe,
ranging from physical disability, to mental
retardation or sudden death. Once the symptoms
of metabolic disease manifest, it is often too late
for treatment to have a good outcome. Thus,
newborn screening is best performed 1- 14 days
after birth to have an optimal outcome.

The neoplastic proliferation of one and rarely two

amplification of a large number of such clones
which produce a single type of immunoglobulin
81
molecule of homogeneous character, belonging to
one of the five classes of immunoglobulins
consisting of one type of two heavy and two light
chains. Apitz (1940) for the first time used the
term ‘paraproteins’ to denote proteins produced
by myeloma cells. The term now stands for
‘monoclonal’ and is coupled with globulin, peak,
spike, component etc. Multiple myeloma, arising
in the marrow of bone, is a predominant plasma

The Clinical Significance of Microalbuminuria

Punjagutta, Hyderabad 500082, AP; [email protected]
Microalbuminuria is associated with adverse
health outcomes in adults. An alarming and steady
increase of diabetics globally warrants the regular screening for microalbuminuria to identify
nephropathy at an early stage during the course
of disease in order to initiate timely intervention.
Diabetic nephropathy and end stage renal disease
(esrd) in india are emerging public health problems and therefore pose real challenge to health
care professionals. Diabetic nephropathy accounts
for nearly 11% deaths in patients of type 2 diabetes. Progression of nephropathy in diabetes patients is the single most common cause of end
stage renal disease (esrd) world wide. An early
detection and proper management of the disease
is therefore essential to prevent the morbidity and
mortality caused by disease. The course of diabetic nephropathy is characterized by urinary albumin excretion (uae) and glomerular filtration
rate (gfr). The association of glycemic control
with microalbuminuria has been established by
various studies. Improving glycemic control, aggressive anti hypertensive treatment and the use
82
of ace inhibitors definitely help in reducing the
rate of progression of nephropathy in type1 as well
as in type2 diabetic patients. Few studies support
the concept that microalbuminuria is not predictive of diabetic nephropathy, but rather is an earlier point in the identification of diabetic nephropathy. The importance of measuring
microalbuminuria is well established however controversies still exists regarding the type of urine
specimen to be used for detecting early renal impairment in diabetic patients. The clinical significance of microalbuminuria in non diabetic population is not fully clear. The microalbuminuria is
also detected in cases of essential hypertension,
systemic lupus erythmatosis etc. The other factors
which are associated with microalbuminuria are
alcohol intake, foot ulcers and smoking. The
awareness regarding the need for regular monitoring of albuminuria and proteinuria is less among
health care professionals in developing countries
like india. Screening for complication is particularly difficult at the primary care level due to lack
of resources, time and training of health professionals.

Biochemical Changes in Mountain Sickness

Traditionally mountain sickness has been regarded
as a dysfunction of respiratory physiology. We
have approached this problem differently based
on our experience during high altitude trekking.
1. We found significant drop in the cerebral blood
flow. This was absent among the Sadhus who were
practising Pranayama. We looked at the influence
of olfactory system on mountain sickness Albino
rats whose olfactory lobes were removed were
subjected to high altitude states under laboratory
conditions Blood and urine samples were
collected at various stages to measure biochemical
parameters. Results suggested that the olfactory
system regulated the pituitary function. High
altitude sickness is primarily a neurological
dysfunction. Olfactory system regulates
physiology at high altitude through its connections
with the median fore brain bundle.
Hypothalamus-pituitary-Adrenal axis is
influenced by the olfactory system through this
pathway. 2. Andean Indians have used coca leaves
(Erythroxylon coca and related species) for
centuries to enhance physical performance.. . The
benefits and disadvantages of using coca leaf have
been a subject of many political debates. The aim
of this study was to investigate the effects of
chewing coca leaves on biochemical and
physiological
parameters.
Cutaneous
microdialysis catheters were used to estimate
systemic biochemical changes. We subjected 10
healthy adult males (local residents) in Cajamarca
(Peru, altitude 2700 m) to a standardised exercise
routine on a stationary cycle ergometer. The blood
pressure, oxygen saturation (digital), pulse, VO2
max and ECG (Holter monitor) were recorded
before the exercise. Cutaneous microdialysis
catheters were introduced in the forearm. . The
subjects were given to chew 8 g of coca leaves
with a small amount of lime. They were then
placed on the cycle ergometer for 20 minutes.
Blood pressure, oxygen saturation, pulse, ECG and
VO2 max were recorded. Pyruvate, glucose,
lactate, glycerol and glutamate levels were
estimated. These results suggest that coca leaves
have blocked the glycolytic pathway of glucose
oxidation resulting in accumulation of glucose and
pyruvate. The energy requirement for exercise is
being met with beta-oxidation of fatty acids. The
glycerol released was also getting accumulated
since its pathway for oxidation was blocked. These
experimental findings suggest that chewing coca
leaves is beneficial during exercise and that the
effects are felt over a prolonged period of sustained
physical activity. The clinical significance of these
biochemical changes will be discussed.

The High Altitude Adaptation Formula

[email protected], www.altitudeclinic.com
We have previously determined that a full
adaptation to high altitude hypoxia is achieved
when the hematocrit reaches a plateau
corresponding to the normal level at that specific
altitude. Adaptation from the hematocrit point of
view, is defined as having three stages: 1) Acute,
first 72 hours, where Acute mountain sickness
(AMS), high altitude pulmonary edema (HAPE)
83
and high altitude cerebral edema (HACE) can
occur 2) Subacute, from 72 hours until the slope
of increase of the hematocrit is 0, where high
altitude subacute heart disease (HAHD) can occur
and 3) Chronic, where the plateau of hematocrit
level begins and where the normal residents
achieve their optimal hematocrit. In this third stage
chronic mountain sickness (CMS) subjects
(polyerythrocythemic patients) present an elevated
hematocrit, above that of normal individuals, for
the same altitude, due to a spectrum of medical
conditions originated fundamentally by cardiopulmonary deficiencies, often un-noticed at sea
level. Adaptation is altitude and time dependent
following the equation:
Time
Altitude
For a fixed altitude the only variable that changes
is Time. Hence the formula becomes a linear
relation such that:
Adaptation in days = Altitude in Km * 11.4.
This simplification is made for easy interpretation
only, as the true equation is quite complex and
follows the exponential change in barometric
pressure. Furthermore, for constantly changing
altitudes such as in mountain climbing, this
formula cannot be used in its simple form. This
formula is again analyzed in an attempt to achieve
a more precise focus.

As the oxygen tension in the inspired air (PIO2)
falls with increasing altitude in normal subjects,
hyperventilation ensues. This acute respiratory
alkalosis is compensated by increased renal
excretion of bicarbonate returning the pH back to
normal. The status is called totally compensated
respiratory alkalosis or chronic hypocapnia. It
seems to be a contradiction that so many normal
people should live their whole lives as acid-base
patients. In 1865 blood gas analyses performed at
3510 m, the PaCO2 (arterial carbon dioxide
tension +-SEM) = 29.4+-0.16 mmHg and pH =
7.40+-0.005. Base excess, calculated with the Van
Slyke sea level equation is - 5 mM (milliMolar or
mmol/L) as an average, suggesting chronic
hypocapnia. Consequently, the Van Slyke sea level
equation for the calculation of base excess must
be adapted to altitude and should be zero. “Base
excess” is misleading, since the essential variable
is not a base and in reality not always an excess
(or deficit). The essential concept is the titratable
hydrogen ion. We have modified Siggaard84
Andersen´s term “concentration of titratable
hydrogen ion” to “Titratable Hydrogen Ion
concentration Difference from normal”, THID
now used, instead of base excess. THID is ideally
determined by titration to a pH of 7.40 at a PaCO2
of 5.33 kPa (40 mmHg) at sea level, oxygen
saturated and at a blood temperature of 37oC. The
THID in vivo is independent of PaCO2, since any
change of PaCO2 implies opposite molar changes
of the bicarbonate and the non-carbonic buffer
concentrations. Consequently, there is no change
in THID, so the value is constant (normally equal
to zero) during acute changes in PaCO2 by hyperor hypoventilation. The buffer capacity of the
carbon dioxide – bicarbonate buffer is high, since
respiratory elimination of CO2 and bicarbonate
excretion of the kidneys rapidly maintains PaCO2.
We have introduced a modified Van Slyke equation
for high altitude (1). Since our Van Slyke equations
operate with normal mean values for PaCO2 at the
actual altitude, a calculation of THID will always
result in normal values - that is zero.

We use a new method to test pulmonary shunt by
hyperoxia at high altitude. The subject is tested
first breathing ambient air in the seated position.
Using a face mask, ventilation, ETO2, ETCO2,
ECG, pulse oximetry and blood pressure are
measured. An arterial blood sample is taken from
the radial artery. The whole procedure is repeated
with the subject breathing 89% oxygen during 6
minutes. A 100 % O2 could be used, but it was
not available. This technique allows for precise
measurements that provide a clear picture of
cardio-respiratory parameters. Furthermore it
allows the possibility of observing when there is
an equilibration of the PIO2 as it is observed on a
breath by breath basis in the same wave that the
ETO2 is observed. The average PIO2 was 421.7
mmHg. For 3510 m, the altitude of our Laboratory,
the test performed in 14 normal subjects (mean ±
SD) using
This tests permits the operator to observe when
the pio2 reaches the maximum level thereby
making the precise observation of shunt,
irrespective of uneven ventilation that can delay
such equilibration of inspired gases. The intrapulmonary shunts are essential for evaluation of
patients with chronic mountain sickness at high
altitude.

Get Together on Biochemistry - An Experimental Teaching
Dr.W.Ebenezer William

This is to share my experiences of experimental
teaching of Biochemistry by programming a Quiz
in Get-together on Biochemical topics which are
minced with extra curricular activities like drawing
rangoli on biochemical structures, group singing
on the themes of ketogenesis, B-complex, TCA
85
cycle and Hemoglobin biosynthesis along with
light music songs, mimicry, skits and instrumental
music by the talented first year Medical & Para
medical students of various Medical Colleges of
Tamil Nadu. The quiz programme had no quiz
master; instead, the participating teams quizzed
each other. The team answering correctly went on
to question the next team and so on. This format
was thoroughly enjoyed by the participants and
spectators. During the rehearsal the interaction of
the students with the Faculty which gives an
extraordinary interest in the subject –
Biochemistry and also during the “Get together”
the students will experience their own leadership
qualities, boldness to face the people by showing
their academic interest and under hidden talents
since the programme is being organized by the
students, for the students and to the students. While
senior Faculty of various Clinical and Para clinical
departments and administrators are felicitating it
motivates the students mind to acquire knowledge
on medicine (Biochemistry) through the Inter –
disciplinary approach. All these efforts are to make
the “Lighter side of the Biochemistry to become a
Brighter one”

The Role of Clinical Chemist in the Management of PatientRay U
Department of Pathology, Royal Hobart Hospital, University of Tasmania, Australia.
Clinical chemistry tests make up 75-90% of the
laboratory tests request laboratories around the
globe receive from the clinicians and others for
the clinical management of health and diseases
of individuals in the society. As the advancement
in the field of medicine progresses so is the advancement in the technology related to the field
of laboratory medicine. Many time consuming and
complex tests are now done easily and within an
acceptable time limit by the instruments. Many
of us believe or try to consider that the need of
clinical chemists is diminishing as the clinicians
can read the tests and move accordingly for the
appropriate clinical outcome. Patients in the hospital system are largely managed clinically by the
junior doctors and in studies done globally found
that laboratory tests are ordered at random, very
few of them understand the implications and many
of them do not even know how to interpret. In a
real time scenario a proactive clinical chemist addressing these issues can substantially contribute
to the delivery of cost effective health service to
the community by using his/her knowledge and
expertise judiciously during the liaison with the
clinicians responsible for the patients’ management
by adding or restricting the tests repertoire to help
in the diagnosis, prognosis, and monitoring of the
patients. If critically assessed a wise and proactive clinical chemist can take a leading role in the
safe and effective delivery of the health service to
the ailing subjects following the principles of evidence based practice of medicine.

Maturity onset diabetes of the young (MODY), characterised by lack of insulin dependence at onusually diagnosed before the age of 25, is a ge- set, absence of ketosis and is autosomal dominant
netically heterogeneous form of diabetes. It is in transmission. Approximately 2% - 5% of pa86
tients with type 2 diabetes fall into the MODY
category. Six genetic forms of MODY have been
recognised. MODY-3 due to hepatocyte nuclear
factor 1a (HNF 1a) is the most common amongst
various ethnic populations with a prevalence rate
of 21% - 64% while MODY-2 caused by Glucokinase gene defect being the second most common
accounts for ~14%. The varied presentation of
MODY poses a problem in the biochemical diagnosis of this condition. Understanding of the criteria for differential diagnosis of Type 1 & 2 diabetes with the MODY type is important as a single
clinical criterion may not apply to clearly delineate the presentation of this condition. The underlying pathogenesis and diagnostic criteria with
examples will be presented

Post -transplant Diabetes Mellitus Following Immunosuppressive Therapy
Dr. Pragna Rao
Professor and Head, Department of Biochemistry, Kamineni Institute of Medical Sciences , Narketpaly,
Andhra Pradesh
Diabetes mellitus is a metabolic disorder that is
also a recognized complication of organ
transplantation. Post-transplant diabetes mellitus
(PTDM) is a form of type 2 diabetes mellitus,
which is thought to develop in response to a
relative insulin deficiency resulting from increased
insulin resistance or impaired insulin production,
or a combination of both. Transplant recipients are
at a particularly high risk of developing PTDM as
a consequence of factors additional to those that
affect the general population, including the
immunosuppressive agents used in transplant
management protocols. PTDM is not a separate
entity, but a symptom of an underlying metabolic
disorder,
which
is
uncovered
by
immunosuppression. While both tacrolimus (TAC)
and ciclosporin (CsA) are known to be associated
with PTDM, the mechanisms underlying this
metabolic disturbance and the relative contribution
of concomitant corticosteroids have been unclear
There is no single, clear definition of PTDM.
Depending on the definition, incidences of
approximately 5-40% have been reported in
patients after renal transplantation. Some
investigators only include those patients using
insulin treatment for a period of at least 30 days ,
while others also include patients taking oral
glucose-lowering drugs (need for drug treatment).
Several risk factors for the occurrence of PTDM
have been described. These include genetic factors,
race, family history of diabetes, older age, obesity,
and the use of calcineurin inhibitors and steroids.
Steroids disturb glucose tolerance by enhancing
insulin resistance. They play a significant role in
the development of PTDM. The mechanism by
which calcineurin inhibitors such as cyclosporine
and tacrolimus may cause impaired glucose
metabolism has not been completely elucidated.
CsA also has an effect on glucose metabolism. In
vitro experiments have shown that CsA dosedependently inhibited insulin secretion . In the
initial report comparing CsA and TAC, it was
mentioned that the incidence of PTDM was
comparable . The pivotal trials, however, showed
significantly higher incidences with TAC . A defect
in insulin synthesis as a result of an mRNA
transcriptional defect was found to be dependent
on duration of exposure to TAC in rats. In clinical
studies, an increase in insulin resistance was
suggested as an additional mechanism underlying
the development of PTDM. Because both
hyperinsulinemia and hyperglycemia are known
to promote atherosclerosis, PTDM probably
contributes to the high prevalence of death from
cardiovascular disease seen in this population.
Furthermore, the preponderance of infections
associated with diabetes mellitus is likely to
increase the risk for sepsis in the transplant
87
population. PTDM is responsible for an increased
incidence of graft failure ; however, to what extent
this is caused by the development of diabetic
nephropathy is not clear Hyperglycemia itself may
upregulate the synthesis of such soluble mediators
of fibrosis in the kidney as transforming growth
factor-ß, which may be important in promoting
mesangial matrix expansion and mesangial cell
hyperplasia. These growth factors are likely to have
a role in the development of chronic allograft
nephropathy, which was the predominant cause of
graft loss in the observational studies of graft
outcome with PTDM.

Point-of- Care testing (POCT)
C.V.Anand
Professor and Head, Dept of Biochemistry, PSG Institute of Medical Sciences and Research,
Coimbatore-641004.
POCT, defined as diagnostic testing at or near the
site of patient care, is to facilitate rapid diagnosis
and faster treatment decisions to improve patient
care and reduce morbidity and mortality. POCT
impacts every branch of the healthcare system.
The devices should be simple to use, robust in
terms of storage and usage and, produce results
that are concordant with the results of the central
laboratory. The results should be consistent with
clinical need and, most importantly, they should
be available without any delay. The POCT
equipment employ different analytical principlesfor example, reflectance, lateral-flow or flowthrough immunoassays, electrochemistry, light
scattering,
immunoturbidimetry,
spectrophotometry, fluorescence and electrical
impedance, to name a few. The most frequently
used equipment is the glucometer, which was
introduced more than three decades ago. POCT
has contributed immensely to the diagnosis of
sepsis, acute coronary syndrome, stroke, GI
bleeding, kidney failure and DKA. Now a whole
gamut of tests are performed using POCT
equipment; cardiac markers- troponins, brain
natriuretic peptide (BNP), NT-pro BNP, blood
gases, plasma lipids, glycated hemoglobin etc. The
major argument against POCT is that, it is carried
out by personnel with no formal training in
laboratory technology. Needless to say that, issues
such as calibration, quality control and
documentation take the back seat. Added to these
are the high costs and poor comparability with
central laboratory results. The advantages of POCT
are reduced TAT, and plausible improved patient
management. POCT has also been shown to lead
to shorter hospital stay and improved health
outcomes. To illustrate, POCT for heart type fatty
acid binding protein (H-FABP), an early marker
of acute myocardial infarction has been recently
introduced, providing a significant benefit for
patients at small rural hospitals.

Protein Misfolding Diseases
Dr.Usha Anand
Professor, Department of Biochemistry, PSG Institute of Medical Sciences & Research, Coimbatore-641 004.
Protein misfolding / conformational diseases diverse disorders which have a common feature at
consist of a group of clinically and pathologically the molecular level; the presence of a protein that
88
acquires a non-native, atypical conformation.
Based on the causative factor, protein misfolding
diseases could be broadly classified into three
categories. a) Reduction in folding efficiency
leading to a fall in the levels of the protein
involved. Cystic fibrosis is caused by defects in
the cystic fibrosis transmembrane conductance
regulator (chloride channel). The misfolded
protein is tagged by ubiquitin and degraded
resulting in a decrease in the levels of this transmembrane protein. b) Diseases in which
misfolding of a given protein results in improper
trafficking. In early-onset emphysema, alpha-1antitrypsin molecules which are formed in the liver
undergo polymerization. They are retained in the
liver and will not reach the lungs. c) Diseases
associated with aggregation of misfolded proteins.
In Alzheimer’s disease accumulation of a betaamyloid peptide leads to the formation of extracellular plaques. A second protein known as ‘tau
protein’ is responsible for neurofibrillary tangles.
AD primarily affects neurons of the hippocampus
and basal fore-brain leading to brain shrinkage and
loss of memory and intellect. Transmissible
spongiform encephalopathies: (Example:
Crutzfeldt-Jakob disease) The misfolding is
initiated and propagated by an abnormal protein
designated as PrPsc (prion protein scrapie), a form
which has extensive beta pleated structure.
Huntington’s disease in which the ‘Huntington
protein’ with polyglutamine repeats have been
demonstrated. Amyptropic lateral sclerosis caused
by mutations in the anti-oxidant enzyme
superoxide-dismutase. Non-functional SOD
aggregates cause this disease. With intense
research in this field the number of diseases
associated with protein misfolding is on the rise.
A thorough understanding of the mechanisms
involved would go a long way in instituting
effective therapeutic measures.

Obesity – A Global Dilemma
V.Parameswaran, L.Blackwell, L.Diggle, J.Burgess and R.McCallum
Diabetes & Endocrinology Services, Royal Hobart Hospital, Tasmania, Australia
Obesity, a leading cause of morbidity and mortality, is associated with a spectrum of diseases particularly diabetes, cardiovascular disease, cancer,
osteoarthritis and breathing disorders. An obese
person runs a 50% increased risk of premature
death than someone of normal weight. Genetic
factors and also environmental factors are involved
in the development of obesity. Around seven million (~ 30%) Australians are in the obese category
and this trend is also reflected globally. Along with
other conditions that are related to obesity, the risk
of developing insulin resistance and diabetes is
also increasing rapidly. Research in finding treat-
ment and effective management is being constantly
sought and trialled to try and mitigate the clinical
effects of obesity. Common approaches include
diet, exercise and lifestyle modifications. Recent
approaches have focussed on newer drugs as also
the additional option of surgery in the management of obesity in those where it is refractory by
other means. The need for appropriate screening
to reduce the risk of developing diabetes is important. Some of these strategies along with dietary
and lifestyle change programs, new diabetes medical treatments, lap-band surgery will be presented
and discussed.

Scholarly Communication: Writing a Research Paper for a Peer-Reviewed
Publication
R S Jayasomu
National Institute of Science Communication and Information Resources (CSIR), New Delhi
Communicating science is as important as doing
science. Knowledge is perhaps the only commodity apart from love and peace that grows when
shared. Science grew effectively only after it was
communicated, shared, and discussed upon. Science writing is not storey writing. It has set rules
and regulations, format and style depending on
what you write about, and to whom you address.
Broadly, science writing can be classified into
popular science writing, writing for encyclopedia, and research communication. Communicating research needs to be focused as it would address specific audience, the scholars. Conventionally, basic units of a research publication include
Introduction, Materials and Methods, Results,
Discussion, Conclusion, Acknowledgement and
References. Data are given either in tables or expressed graphically through illustrations. Abstract
and keywords are given in a separate sheet, pref-
erably in the beginning following the covering letter and declaration. Generally, first page of a manuscript should have the Title, name(s) of author(s),
their affiliations, contact address of author for correspondence, abbreviations, if any, and a short title.
Tables and illustrations are given separately after
references. Care should be taken that the table data
are not repeated as illustrations. Legends or captions of illustrations are to be typed separately in a
page.
Once the data are ready after your experiments, it
is necessary to find an appropriate journal for communicating the results of your research work. Papers published in non-core journals seldom get
their due citation. In the present paper, I intend to
share my knowledge gained during the last two
decades in this profession of science editing on
how to write a research paper

Urine Albumin: Standardisation and Reporting Issues.
H. D. Martin
Gribbles Pathology, 1 Goodwood Rd, Wayville, SA 5034, Australia
Urine albumin is well established as an early marker
for nephropathy in diabetic subjects. More recently it
has also been identified as an important prognostic
marker in hypertension and cardiovascular disease.
Despite the literature supporting clinical utility there
is evidence that clinicians do not often request urine
albumin, particularly in their non-diabetic patients.
Furthermore, when they do make the request, they find
interpretation confusing and adherence to guidelines
is poor. Currently there is no reference system for the
90
measurement of urine albumin: in particular the
measurand is not defined, there is no reference material and although the manufacturers of the majority of
methods in routine laboratory use the same calibrator
source, it is a serum based material and individual
preparations are not standardised. Despite this, the
analytical variation represents a small proportion of
the total error in urine albumin measurement. It is the
pre-analytical phase which contributes the major variation. Albumin excretion rate (AER) and albumin crea-
tinine ratios (ACR) vary substantially with collection
type and patient preparation. Daytime collections yield
significantly higher results than nightime collections.
Exercise, stress, posture, infection, hydration and blood
contamination can contribute to bias in both AER and
ACR. Creatinine variation will contribute significantly
to variation in ACR but reference ranges are not age/
gender/race specific. Decision points for urine albu-
min, AER and ACR in common use vary widely and
none has been clinically validated for the particular
method. The NKDEP/IFCC has a urine albumin working group that is collaborating with other professional
groups to work towards standardisation; in the meantime individual laboratories can play a crucial role in
educating health care providers.

Molecular Mechanisms of Angiogenesis in Heart and Lung
Hari S. Sharma
Angiogenesis and Tissue Remodeling Group, VUMC, Amsterdam and Erasmus MC, Rotterdam,
The Netherlands
Right ventricular hypertrophy and failure are
common features in patients with tetraogy of Fallot
(TF). Myocardial angiogenic gene expression
profile was examined in patients with right
ventricular hypertrophy and failure in order to
assess myocardial vascularisation. DNA
microarray analysis on right ventricular biopsies
from TF-patients operated for primary corrective
surgery (TF-1, n=8, mean age 0.5 year) and age
matched controls was validated by Northern
hybridization and RT-PCR. Employing
immunohistochemistry and video image analysis
expression of vascular endothelial growth factor
(VEGF), vascular density (by a-SMA and CD31
staining) and myocyte cross sectional area
(Gomori’s reticuline staining) were assessed in
TF-1 and adult patients (TF-2, n=8, mean age 30
years) who underwent surgery for pulmonary
regurgitation and compared the data with age
matched controls. DNA microarray analysis
revealed altered expression pattern for several
genes including angiogenic factors, VEGF, flt-1,
flk-1 angiopoietin-2, FGF-2, FGF-R1, PDGF-A,
whereas, flt-4, Tie, TGF-b, TGF-b3R showed
decreased expression in TF patients. Northern blot
analysis verified VEGF expression whereas, flk1 expression remained unaltered in both TF-1 and
TF-2 patients. VEGF staining in cardiomyocytes
was increased in TF-1 as compared to TF-2. Video
image analysis revealed enhanced vascular density
with unchanged wall thickness and enlarged
myocyte cross sectional area in both TF-1 and TF2 as compared to respective age matched controls.
Right ventricular hypertrophy is associated with
an altered gene profile for a number of genes where
the VEGF/VEGF-R system plays an important role
in enhanced myocardial angiogenesis with limited
vascular remodeling.
In another set of experiments
Mechanisms of angiogenesis were studied using
human Cell culture based in vitro models. We have
shown that different growth factors and cytokines
result in differential gene expression and secretion
of various proinflammatory cytokines and vascular
endothelial growth factor (VEGF), an angiogenic
molecule in cultured human ASM cells. To assess
the role of airway smooth muscle (ASM) in
bronchial angiogenesis and remodeling, we
investigated the production of VEGF in ASM cells
in relation to mediators of asthma, such as, IL-1b,
TNF-a, TGF-b, ANG II and ET-1. Time dependent
release of VEGF protein in the conditioned
medium was observed which in its turn induced
proliferation and growth of pulmonary artery
endothelial cells. We further investigated the
effects of nitric oxide (NO) pathway on the pro91
inflammatory cytokine; Interleukin-1b (IL-1b)
induced expression and secretion of VEGF and
PlGF. Serum deprived (for 48h) ASM cells were
stimulated with IL-1b (5 ng/ml), IL-1b + Nw-nitroL-arginine methyl ester (L-NAME), IL-1b + Larginin and IL-1b + L-NAME + L-arginine for 4
and 24 h. NO synthase inhibitor (L-NAME) was
used 1h prior to IL-1 incubation in all experiments.
IL-1b induced expression (1.8 fold vs control) of
VEGF mRNA (quantitative RT-PCR) was
attenuated by L-NAME and augmented by Larginine. L-NAME inhibited the secretion of
VEGF and PlGF in conditioned media of IL-1b
treated PASMC at 4 and 24 h, respectively. By
restoring NO pathway (L-arginine treatment) in
L-NAME treated cells led to elevated (2.2 fold)
expression of VEGF. Taken together, our findings
suggest that a cytokine cascade involving mainly
IL-6, IL-8 and VEGF operates in hyper contractile
human ASM cells where NO pathway may
modulate VEGF signaling during airway
inflammation and subsequently contributing to
bronchial angiogenesis and airway remodeling in
patients with asthma and COPD.

The Pro-Inflammatory Role of Extracellular RNA in Arteriogenesis
Elisabeth Deindl
Walter-Brendel-Center for Experimental Medicine ; Ludwig-Maximilians-University Marchioninistr.
27 D-81377,Munich,Germany
The growth of pre-existing arteriolar anastomoses
to large conductance arteries (arteriogenesis) is
the most important tissue-, organ-, and often life
saving process after arterial occlusions. It can be
so efficient that occlusions of coronary, peripheral,
renal, and cerebral arteries may occur without
tissue loss and even without loss of function. The
initial trigger for the growth of those natural
bypasses is fluid shear stress activating the
endothelium surface, thereby leading to
modulation of processes controlling the
recruitment of circulating cells. The inflammatory
aspect of this activation is apparent by the
increased expression of ICAM-1 as well as of
MCP-1, a chemoattractant protein responsible for
the adhesion and migration of monocytes to the
endothelium. Recently, extracellular RNA was
described to act as “danger signal” and trigger
immune response. In order to investigate the
function of extracellular RNA in an animal model
of arteriogenesis, the right femoral artery of mice
was ligated and the left was sham operated.
Arterial growth was measured via Laser Doppler
Imaging (LDI) and quantified as relative perfusion
92
recovery (right/left) before and after surgery until
day 7. Treatment with RNase, but not with DNase,
immediately before occlusion of the artery until
day 7 significantly reduced the extent of
arteriogenesis (perfusion recovery in untreated or
DNase treated mice: 83%, in RNase treated mice
44%), suggesting that extracellular RNA plays a
role in the process of arteriogenesis. Accordingly,
in vitro studies confirmed that RNA acts as a
chemoattractant for monocytes. In an endothelial
cell monolayer the migration of monocytes was
increased by RNA to nearly the same extent as by
MCP-1. In addition, there was an increase in
adhesion of monocytes to microvascular
endothelial cells by RNA, but not by DNA. The
expression of ICAM-1 on endothelial cells was
increased by RNA and abolished in the presence
of RNase. Furthermore, RNA led to exocytosis of
pro-inflammatory factors like P-Selektin from
Weibel-Palade bodies. In summary, our data
indicate that extracellular RNA promotes the
process of arteriogenesis by immune-modulating
effects.

Pharmacogenomics: One Size Does Not Fit All
Dr. Amit Chakrabarti.
Professor of Pharmacology, Sikkim Manipal Institute of Medical Sciences, Gangtok, Sikkim 737 102, India
Pharmacogenomics is the study of how an
individual’s genetic environment influences
response of drugs. It is thus an intersection of
pharmacology and genetics. Although the
knowledge that genes may influence action of
drugs was present since the 1930s, major advances
occurred only in the last couple of decades.
Fundamentally, pharmacogenomics conveys the
message that no two persons are similar with
respect to effect of drugs, because everyone has a
different genetic milieu. This essentially promises
that one day extremely safe drugs could be tailored
considering a person’s genetic constitution.
Therefore,
potential
benefits
of
pharmacogenomics include 1) synthesis of more
disease specific medicines, with less potential of
damaging healthy cells; 2) prescription of best
drugs for a particular patient considering genetic
constitution; 3) more appropriate dose titration of
medicines; 4) early screening for genetic diseases;
5) safer and cost-effective vaccines; 6) simpler
drug development process identifying subjects
with a particular genetic make up for a particular
drug; and 7) overall reduction in health care costs.
As of now pharmacogenomics is in limited clinical
use. Most prominent use is for identification of
variants of the cytochrome P450 enzyme system.
Before clinical trials investigators can detect if the
trial participant has a different form of P450
enzyme, which may reduce drug metabolism and
increase chance of adverse events.
Pharmacogenomics is in its infancy and has a
number of barriers to overcome before becoming
truly applicable in everyday clinical practice. Some
of the barriers to successful clinical translation are
1) large number of gene variations affecting drug
action; 2) drug choices are not sufficient to account
for all variations; 3) developing a number of drugs
to fit different genetic make ups is not a costeffective drug development option; 4) drug
prescription according to pharmacogenetic profile
will be a complex process involving further
diagnostic tests and intensive training for treatment
providers.

Lead is one of the toxic heavy metals, which is environmental as well as health hazard, affecting
globally considered as the number one people of all age groups. It has deleterious effect
93
on all organs in the human body. Lead poisoning
is widely recognised as a major public health
problem all over the world.
Every moment, we are building a stock of Lead in
our body. Lead from our house paints, drinking
water, food staffs, glossy cosmetics accumulate
in our body creating a stock of unwanted toxic
chemical – Lead Poisoning, a “Silent Epidemic”.
The human body cannot process and expel lead.
Sustained and close contact can cause serious
damage to developing central nervous system and
brain that leads to a child performing poorly in
exams or having short attention spans. Adults who
are exposed to lead poisoning many find it difficult
to concentrate or remember things and feel pain
in muscles and joints.
Children and women are found most vulnerable
to lead poisoning (also known as saturnism,
plumbism, or painter’s colic). Lead may cause
irreversible neurological damage as well as renal
disease, cardiovascular effects, and reproductive
toxicity.
Lead level in blood exceeding 10 ug/dl (recently
2.0 ug/dl) is considered as unsafe, but studies
indicate that over 60% of children in India may
have more than this level in their blood.
Unlike other health hazards, lead poisoning is
100% preventable by early diagnosis and
prevention of exposure by awareness.
Paint manufacturers have the capability and
technology to phase out lead from their products.
But costs being an issue, companies complain that
making lead free products makes the product
expensive, and lowers their market share. It is
therefore, even more important to have mandatory
standards for all branded companies globally. The
environmental regulation should not be confined
to production but extended to products we use.
The awesome effect of the “silent epidemic” needs
to be understood and propagated to the mass for
their awareness and effective prevention - thus
“help yourself and others too”.

The IFCC Scientific Division and NKDEP
Laboratory Working Group called for more
specific creatinine methods to be adopted, and the
introduction of enzymatic creatinine methods has
effectively removed the major interferences seen
with the chemical Jaffe reaction.
The improved accuracy of enzymatic creatinine
has advantages in a number of patient groups. In
particular, for children and neonates where the
correction factors for protein interference are
inappropriate, enzymatic creatinine measurements
are required.
Also, eGFR is unreliable when greater than 60 mL/
min/1.73m2 and a single creatinine measurement
is insensitive to moderate reductions in GFR.
Cystatin C measurement overcomes many of these
problems. It is produced consistently and is freely

A Study on Free and Total Prostate Specific Antigen in Benign Prostatic Hyperplasia
(BPH) and Carcinoma Prostate
Dr. R. Lalitha
Associate Professor Biochemistry, Stanley Medical College, Chennai – 600001
Objective: The molecular forms of Prostate
Specific Antigen (PSA) are Free PSA (unbound)
and bound forms – PSA á (antichymotrypsin) and
PSA á 2 (macroglobulin). Studies established that,
in BPH more free form is present than CA Prostate.
This study aimed to evaluate free and total PSA
in BPH and CA prostate and the ratio between free
PSA to total PSA (which is % Free PSA) in
discriminating between these two diseases. Free
PSA and total PSA are correlated with, prostatic
volume, total acid phosphatase, prostatic acid
phosphatase, total PSA density and free PSA
density.
Methods: The study was carried out on 79
patients of age 50 and above. They constituted
40 normal, 24 BPH and 15 CA Prostate patients.
Serum total PSA and free PSA were estimated by
a microplate Enzyme immunometric assay (EIA).
Results: The two diseases were differentiated at
cut off level of 6 ng/ml (sensitivity 42%, specificity
88%) of total PSA, and 0.5 ng/ml of free PSA
(sensitivity 58%, specificity 88%). In, % free PSA.
A cut off level of 0.1 is established between
controls and prostate diseases, but a suitable cut
off for the 2 diseases was not established.
Conclusion: Free PSA, Total PSA, and % free
PSA increased in prostate cancer, but not in
controls. On contrary to the previous studies, there
was no difference in any of the three entities,
namely, total PSA, free PSA and % free PSA,
between the two diseases. Among the biochemical
parameters evaluated, total and prostatic acid
phosphatases are better indicators in differentiating
between BPH and CA Prostate in patients with
increased prostatic volume.

cervical cancer patients 40.96 ± 8.45 U/L. A
significant increase in GGT was observed in
cervical cancer patients when compared to controls
(p-value < 0.001)
Conclusions: Present study suggests that serum
adenosine deaminase and gamma glutamyl
transferase may be used as supportive parameters
for diagnostic purpose and may add further for
prognostic information. These biochemical
parameters are inexpensive, rapid and can be easily
analysed in smaller laboratories which have not
exposed to any sophisticated technology.

Postgraduate Institute of Medical Sciences, Rohtak (Haryana), Email: [email protected]
Objective: Osteosarcoma is a rare malignant bone
tumor, most commonly occurring in children and
young adults, presenting with painful swelling.
Various etiological factors include ionizing
radiation, family history of bone disorders and
cancer, chemicals such as fluoride, beryllium and
vinyl chloride, and viruses. Glycoproteins and
glycosamino-glycans are integral part of bone and
prolonged exposure to fluoride, for long duration,
has been shown to cause degradation of collagen
and ground substance in bones.
Methods: The present study was therefore
planned to analyze serum fluoride, sialic acid,
calcium, phosphorus, and alkaline phosphatase in
25 patients of osteosarcoma, and age and sex –
matched patients with bone-forming tumors other
than osteosarcoma, and a group of patients with
musculo-skeletal pain as controls. Fluoride was
estimated by ISE, and sialic acid by Warren’s
method. Mean serum fluoride concentration was
found to be significantly higher in patients with
osteosarcoma as compared to the other two groups.
Results: Mean serum fluoride concentration in
patients with other bone-forming tumors was
nearly 50% of the group of osteosarcoma, however,
it was significantly higher when compared with
group I. serum sialic acid concentration was found
to be significantly raised in patients with
osteosarcoma as well as in group with other boneforming tumors as compared to the controls.
Conclusion: Results suggest a role of fluoride in
the disease.

Objective: The occurrence of breast cancer in
women is one of the most common neoplastic
conditions. Unfortunately at present the diagnosis
of breast cancer by biopsy remains only option
for the confirmation of the condition. We
investigated the possibility of the use of the
determination of plasma maspin level for the
diagnosis of cancer.
Methods: Maspin (a mammary serpine inhibitor),
an anti breast cancer protein produced abundantly
in the normal mammary epithelial cells but not in
malignant breast tissue. Maspin was assayed by
enzyme linked immunosorbent assay (ELISA). A
total of 35 female breast cancer patients (between
the ages of 45-65) participated in the study. An
equal number of age matched female volunteers
also participated in the study. None of the cancer
patients at presentation underwent any therapy for
the condition. The staging were T-1=6, T2=8,T3=9,
N0=5, N1-N3= >, stage I+II=30, Stage III=5,M0=0.
Maspin was assayed in the collected blood sample
as soon as practicable.
Results: The plasma maspin level was
4.67±0.04nM in normal volunteers (n=35). In
contrast basal plasma level of maspin was
0.95±0.01nM (n=35, p<0.0001). Furthermore
decrease of plasma maspin level was inversely
related to the increase of malignancy grade of the
condition.
Conclusion: Plasma maspin level could be a useful
marker for the diagnostic test for human breast
cancer.

Serum sialic acid forms as tumors head, neck, thyroid & lung tumors.
Mahendra R. Pakhale , Dr.Murhar and Rajesh Rajrkar
Dept. of Biochemistry, Yavatmal (M.S)
Objective: Serum sialic acid levels are
significantly elevated in thyroid tumors, head &
neck, lung tumors. Such elevation correlate with
tumor progression & metastasis. Generally serum
lipid bound sialic acid levels are elevated in cancer
patients.
Methods As compared to healthy subjects &
patients with chronic non-tumors diseases.
Patients with metastatic disease have higher values
than ones with localized tumors. Serum sialic acid
levels are often elevated in patients with lung
cancer. Patients in clinical remission following
chemotherapy also show elevated mean serum
sialic acid levels. Sialic acid levelsare also
increased in nonmalignant growth of breast tissue
during pregnancy & lactation. Despite the low
specification of serum sialic acids as tumor
markers their levels seem to be related to clinical
course of disease & could be useful in the
monitoring of tumor progression.
Results:Total sialic acid levels were also found to
be increased in serums from lung cancer patients
as compared to the healthy controls. in patients
with metastases these levels are further increased.
As a rile serum lipid bound sialic acid is elevated
in serums from patients with lung cancer. Lipid
bound sialic acid serum changes could be
correlated with the extent of disease.In some of
the studies no statistically significant difference
between patients with chronic non tumor diseases
& cancer patients could be established. However,
lipid bound sialic acid levels are significantly
higher in patients with metastatic disease compared
to ones with loclized timor. Serum lipid bound
sialic acid levels hanged during intensive
chemotherapy almost parallel with the clinical
course, & hence lipid bound sialic acid can be of
99
potential use for following the course of
chemotherapy.
Conclusion: Combined measurements of total
sialic acid & lipidbound sialic acid in serum from
patients with lung cancer could be more
discriminatory than values of either of these
markers. Combination of these markers might be
useful for differentiation between benign &
malignant conditions & also for diagnosis of
metaststic lung cancer. Comparison between total
sialic acid & lipid bound sialic acid values could
also discriminate between different tumor types
or between patients with & without metastases.

Role of Serum Enzymes in Oral Cancer.
Dr P.B Desai and Dr. Shikha Sharma
Department of Biochemistry, J.N Medical College, Belgaum, Karnataka,Email:[email protected]
Introduction: Oral cancer is the most common
type of Head and Neck cancer and is a major health
problem in developing countries. The survival
index is small (50%) as compared to the progress
in the diagnosis and treatment of other tumours.
Thus there is a need for the improvement in
detection of early stages as treatment is more
effective and morbidity minimal. A majority of
the initial alterations in these lesions are not readily
recognizable on clinical or histopathological
examination. Therefore a number of biochemical
markers have been studied to evaluate the
malignancy. In view of this, the present study is
undertaken to provide some promising biomarkers
namely Adenosine deaminase (ADA) and 5’Nucleotidase (5’-NT) which are inexpensive,
accurate and identifiable by easy methods of
detection and therefore may be of some diagnostic
and prognostic significance.
101
Methods: A total of 20 clinically and
histopathologically confirmed male patients of
oral cancer in different stages were included in
the study. There were in the age group of 35-65
years. Normal subjects were taken as controls. 5ml
of blood was drawn and ADA was estimated by
method of Galanti and Giusti and 5’-NT by method
of Campbell.
Results: The levels of ADA and 5’-NT were
significantly elevated in oral cancer patients in
comparison to controls. An increase in these
biomarkers was also seen when interstage
comparison was done.
Conclusion: The rise in ADA and 5’-NT activity
in cancer patients occurs due to enzyme leakage
from the primary cancerous or metastatic tissue.
The rise in activity in relation to the stage further
suggest that increase in tumour mass may be
directly responsible for the increased levels of the
enzyme. Thus these markers are of diagnostic and
prognostic significance in case of Oral Cancer.

Background: The incidence of 22q11 deletion
syndrome is found to be 1 in 4000 live births. Gene
dosage reduction like heterozygous deletion of
chromosome 22q11.2 region leads to 22q11
deletion syndrome. Phenotypic variability is one
of cardinal feature of this syndrome. Cardiac
mainly conotruncal defects, hypoparathyroidism,

Objective: Hypoxia at birth causes changes in
brain neurotransmitters depending on its severity
and durations. Serotonin (5-hydroxytryptamine;
5-HT) is one of the major neurotransmitters
participating in the development of hypoxiainduced pulmonary hypertension. Ventilatory
long-term facilitation during hypoxia requires 5HT2 receptors. We investigated the 5HT2A receptor
functional regulation in the cerebral cortex of
hypoxia induced neonatal rats and the role of
glucose and oxygen supplementation in regulating
the receptor alterations due to hypoxia.
Methods: Wistar neonatal rats of 4 days old used
for the experiments were grouped into five as
follows: (i) Control (C); (ii) Hypoxia (Hx); (iii)
Hypoxic neonatal rats injected with 10% dextrose
(500mg/ Kg body wt) intra-peritoneally (i.p.)
(Hx+G). (iv) Hypoxic neonatal rats injected with
10% dextrose (500mg/ Kg body wt) i.p. and
treated with 100% oxygen (Hx+G+O); (v)
Hypoxic neonatal rats treated with 100% oxygen
(Hx+O). 5HT2A receptor was assayed according
to the procedure of Uzbekov et al, 1979.
Results: Under hypoxic condition neonatal rats
showed a significant increase in receptor number
(B max) with a decreased affinity (p<0.001).
Resuscitation with glucose (Hx + G) and glucose
along with oxygen (Hx + G + O) showed a
significant reversal to near control. Hypoxic
neonatal rats treated with 100% oxygen (Hx + O)
showed a significant increase in Bmax (p<0.001)
compared to control. Real Time PCR analysis also
showed a significant increase (p<0.001) in the gene
expression of 5HT2A receptors in hypoxic neonates.
The gene expression showed a reversal to near
control in Hx + G and Hx + G + O. Pulmonary
hypertension during hypoxia can be attributed to
the increase in 5HT receptors in the cortex. Glucose
alone and glucose + oxygen supplementation
reversed the altered receptors in the developing
brain of hypoxic neonatal rats.
Conclusion: This has clinical significance in
neonatal care and healthy intellect during later
developmental period.

Vidyapeetham, Cochin-682041, Kerala, India. Email: [email protected]
Objectives
1) . To screen 420 patients with signs and
symptoms of organic aciduria / aminoaciduria.
2) To identify and quantify organic acids and
amino acids by HPLC.
Methods: Manual screening tests and thin layer
chromatography were used to detect the presence
of abnormal metabolites in urine. HPLC was done
for organic acid and amino acid analysis using
standard protocols. Clinical details of the patients
were collected from proforma. CT/MRI were used
to evaluate the brain abnormalities.
Results: We studied 420 children upper age limit
12 years with signs and symptoms of organic acid
/ amino acid disorders. Abnormal cerebral CT/
MRI findings were found in 11 patients, and
abnormal EEG findings in 63 patients. 110
samples found positive for organic acids by initial
screening tests. Out of which 41(9.7%) cases of
Organic acidurias were diagnosed by HPLC. 15
cases of Methylmalonic aciduria, 16 cases of
Propionic aciduria, 7 cases of Maple syrup urine
disease, 2 cases of Alkaptonuria and 1 case of
Isovaleric aciduria were found. Common
symptoms of Organic aciduria patients were
seizures (N=17), delayed milestones (N=12), skin
rashes (N=10), abnormal muscle tone (N=6), poor
feeding (N=12), mental retardation (N=12),
encephalopathy (N=1) and hyperammonemia
(N=30). 10 patients were from consanguineous
families. 15 patients expired during the study.
Conclusion: Methylmalonic aciduria, Propionic
aciduria and Maple syrup urine disease account
for 90% of organic acidopathies detected. HPLC
quantification of amino acids and organic acids
helps to identify organic acidurias. Prompt
diagnosis allowed specific treatment in majority
of these patients with rapid improvement.

Objective: Inborn errors of metabolism (IEM)
may occur anywhere in the biochemical
machinery of living cells. Although some 150-200
inborn errors of metabolism of clinical interest
are known at present, a few thousand enzymes
and structural proteins have so far been described

in human cells; thus it is likely that the types of
inborn errors so far described represent only a
fraction of those actually occurring. A large number
of inborn errors of metabolism in children remain
undetected in India due to lack of awareness,
investigative facilities and economic constraints.

Sciences, KERALA
Type 1 hyperprolinemia is biochemically
characterized by a defect of the proline
dehydrogenase enzyme (McKusick 239500). The
enzyme has been mapped to the PRODH gene on
the human chromosome 22 on band q11.2. This
gene falls in the region deleted in the 22q11
Deletion Syndrome, which includes DiGeorge and
Velo-cardio-facial syndromes. Neurological
manifestations have been reported in several
hyperprolinemic subjects. The paucity of previous
research in this subject in India is investigated this
study.
Methods: Plasma proline levels were assayed
(using high pressure liquid chromatography) in 14
children affected with 22q11 deletion syndrome.
The neurological and development statuses of the
hyperprolinemic subjects were studied.
Results: Seven subjects had proline levels above
normal and seven were within the normal limits.
Three subjects had varying degrees of
psychomotor deficits, including delayed
milestones, global developmental delay and
decreased IQ.
Summary: In concordance with previous studies,
this study finds that hyperprolinemia is a common
finding in 22q11 deletion syndrome. Besides, it is

Hypoglycaemia
Biswajit Saha
Durgapur Steel Plant Hospital, Durgapur – 713 205, West Bengal (India); e-mail :
[email protected]
Hypoglycaemia is a medical emergency. In day caused by “over administration” of antidiabetic
to day clinical practice, this condition is commonly drugs. Hypoglycaemia is defined when the plasma
105
glucose level is usually less than 45 –50 mg/dl.
However, chemical hypoglycaemia is not
synonymous with clinical hypoglycaemia which
requires demonstration of Whipple’s triad –
symptoms consistent with hypoglycaemia,
documentation of a low plasma glucose
concentration and relief of symptoms after plasma
glucose level has been raised. Interestingly, the
threshold for hypoglycaemia varies widely in an
individual diabetic patient as a result of alteration
of metabolic setpoint from time to time in different
clinical settings. Relative hypoglycaemia occurs
with blood sugar level above 50mg/dl. Conversely,
remarkable lowering of threshold is found in
diabetic patients as a result of recurrent attacks of
hypoglycaemia. Surprisingly, in some otherwise
normal (nondiabetic) individuals, marked lowering
of blood glucose level is not associated with any
symptom(s). The details of causes, clinical
manifestations and management will be discussed.

Dyslipidemias
Prof. N. Haridas
Professor and Head, Department of Biochemistry PS Medical College, Karamsad
The Plasma lipoproteins are spherical
macromolecular complexes of lipids and specific
proteins (apoproteins or apolipoproteins). The
lipoprotein particles include chylomicrons, very
low density lipoproteins (VLDL), low density
lipoproteins (LDL) and high density lipoproteins
(HDL).They differ in lipid composition, size,
density and site of origin. Lipoproteins function
both to keep their component lipids soluble as they
transport them in the plasma and to provide an
efficient mechanism to transport their lipid
components to (and from) the tissues. In humans,
the transport system is less perfect than in other
animals and, as a result, humans experience a
gradual deposition of lipid-especially cholesterolin tissues. This is a life threatening occurrence
when the lipid deposition contributes to plaque
formation, causing the narrowing of blood vessels
(atherosclerosis). The talk shall include a
discussion on the metabolism of lipoproteins and
lipids and how their metabolism alters in diseases
like diabetes mellitus, metabolic syndrome,
familial hyperlipo-proteinemias, obesity and
athero-sclerosis. Mention also shall be made about
blood investigations like lipid profile and other risk
factors like lipoprotein ‘a’, homocysteine, creactive protein and dietary fat. Certain preventive
measures like dietary modifications to ward off
atherosclerosis and subsequent heart ailments
would also form a part of the discussion.Certain
interesting observations on lipd profile soon after
acute myocardial infarction shall be discussed.

Requirement of Essential Fatty Acids: An Analytical Approach
Dr. Sankar Roy
Asst. Prof., Tripura Medical college & Dr. BRAM Teaching Hospital, Hapania , Agartala- 799014,
Tripura
Each animal or plant species has a specific pattern
of fatty acid composition in their body. Human
body contains more unsaturated FA(60%) than
saturated FA(30%). This ratio (2:1) is essential to
maintain structural and metabolic function of cell
membrane. Body synthesizes Eicosa pentaenoic
acid, Docosa hexaenoic acid and Prostaglandins
from essential fatty acids. But if the dietary PUFAs
are in excess , they compete with or inhibit
phospholipases and acyltransferases. The dietary
PUFAs are incorporated into the structural lipids
about 20 times more than the ve novo synthesized
long chain fatty acids.
Ratio of w-6 / w-3 is also to be maintained about
1:1. But modern diet contain more than 10:1.
Therefore, it is recommended to consume more
w-3 fatty acid containing foods like Soybean oil
(7%), vegetable oil, marine fish to equalize w-6
but not in excess amount.

Dept of Biochemistry, Amrita School of Medicine, Kochi, Kerala, INDIA. Email: [email protected]
Objective: Organic aciduria is a group of
disorders characterized as autosomal recessive. It
is primarily due to defect of an enzyme, which
results in block in a particular metabolic pathway.
A pilot study was done to identify and quantify
the different Organic acids using HPLC.
Methods: The study was carried out at Amrita
Institute of Medical science and Research centre,
Kochi. 184 urine samples were taken from Organic
aciduria suspected children between the ages of 0
– 15 years during a time period of one year from
May 2008 – April 2009. Initially samples were
screened for Organic acids by thin layer
chromatography. This was followed by HPLC to
confirm the presence and to identify and quantify
the individual Organic acids.
Results: For the study, 184 urine samples were
screened, 39 showed organic aciduria by screening.
26 were confirmed as positive cases on further
detection using HPLC. There were 34.6% cases
of Propionic aciduria, 26.9 % cases of
Methylmalonic aciduria and 7.6% cases of lactic
aciduria.
Conclusion: This study shows that the incidence
of Organic aciduria is high and HPLC helps in the
easy detection of individual organic acids present
in the urine from which the metabolic disorder can
be confirmed. Thereby, early treatment can be
initiated to avoid morbidity and mortality.

Gastroenterology, Amrita Institute of Medical Sciences and Research Centre, Kochi-682041,
Kerala, India. [email protected]
Background: Inflammatory bowel diseases (IBD)
are chronic intestinal disorders of unknown
etiology and with a typically relapsing course.
Faecal calprotectin, an important granulocyte
cytosolic protein, is closely correlated with faecal
excretion of 111 indium labelled leucocytes,
deemed to be the gold standard for measuring
intestinal inflammation. Assessment of faecal
calprotectin levels has been proposed as a noninvasive test for the direct evaluation of intestinal
inflammation in patients with IBD.
Objective: To compare faecal Calprotectin with
the standard disease activity indices (UCAI and
CDAI) of inflammatory bowel diseases
(Ulcerative colitis and Crohn’s disease).
Methods: Patients diagnosed to have IBD based
on clinical, endoscopic and histological
examination were included. Ulcerative colitis
activity index (UCAI) and Crohn’s diseases
activity index (CDAI) were calculated. Faecal
calprotectin was estimated by a commercially
available quantitative ELISA test.
Results: Forty-three patients were included in the
study, 20 patients with Ulcerative colitis (UC) and
23 with Crohn’s disease (CD). Patients with active
CD (CDAI > 150) were 18/23 (78%) and with
active UC (UCAI > 2) were 17. Mean hemoglobin
was not different in both the groups. Mean ESR
was raised in both groups (37 in UC, 31 in CD; P
= 0.361). Mean CRP was raised in both groups
(UC 49± 60; CD 19±19; P= 0.302). Mean UCAI
was 7 (SD± 3) and mean CDAI was 212 (SD ±
89). Mean faecal calprotectin was 890 (SD±503)
in UC patients and 641 (SD±739) in CD patients
(P = 0.028) Fecal calprotectin was higher in active
cases compared to those in remission but the
difference did not achieve statistical significance.
Correlation of faecal calprotectin with CDAI was
strong (P = 0.0008) whereas correlation of faecal
calprotectin with UCAI was weak (P = 0.274).
Conclusion: Faecal calprotectin correlated
strongly with CDAI but weakly with UCAI. The
difference in patients in remission vs active disease
(as categorized by UCAI and CDAI) was not
statistically significant.

A Study on Cytotoxicity and Inhibition of Cyclooxygenase-2 by Curcumin and Diallyl
Sulfide in Head And Neck Cancer Cell Line
Hariharasudan. R
Final year MBBS, Amrita Institute of Medical Sciences, Kochi , Kerala. Email: [email protected]
Objective: To study the effect of curcumin and
diallyl sulfide (DATS) on cytotoxicity and
inhibition of Cyclooxygenase (COX-2) in head
and neck cancer cell lines
Results: The study showed that the IC50 values
for both DATS and curcumin was 5ì M. With
regard to the regulation of COX-1 and COX-2
expression, curcumin and DATS inhibited COX-2.
Methods: MDA 686LN a HNSCC cancer cell
line, maintained in MEM was teated with DATS
and curcumin individually for 24,48 and 72 hours
with a zero hour control in triplicates. The cells
were harvested by trypsin treatment and cell
viability was determined by trypan blue dye
exclusion assay. Total RNA was isolated using
TRIZOL solution and its integrity was checked.
The cDNA was synthesized using both oligo-dT
and random hexamer primers. The level of COX1 and COX-2 expression was analyzed by PCR
in comparison with â-actin using specific primers.
Conclusion: Currently, curcumin has been
introduced into clinical trials in the
chemoprevention of HNSCC and the only
difficulty is its bioavailability. The cytotoxicity
study, using the HNSCC cell line namely MDA
686LN indicated that curcumin and DATS have
greater effect on cell viability. It is proposed that,
the synergistic effect of the combination of
curcumin and DATS should be greater than the
individual clinical compounds. Further studies in
this aspect are currently taken up.

A Study for Investigating the Association between Semen Biochemical Parameters
and Routine Clinical Semen Parameters in Infertile Men
*
Suresh S. and T. Vijayakumar
Department of Biochemistry and Physiology , Educare Institute of Dental Sciences,
Malappuram-675 506, Kerala ,India.
Objective: The biochemistry of semen has been
studied extensively,but the biochemical analysis
of semen has little part to play in the routine
investigation of an infertile man. 1-4 In this context
a study was undertaken with the objectives of
investigating whether there exists an association
between semen biochemical parameters and
clinical semen parameters, so that the latter could
112
be used as an adjunct to the conventional semen
analysis for evolving better seminogram
protocols in the evaluation of male infertility.
Methods: For the present study , semen samples
of 120 infertile men visiting an Infertility Clinic
were collected and the same was used for the
investigations. The study followed the ICMR and
WHO Ethical Guidelines
for Clinical
Research.The 120 infertile men were divided in
to 3 groups: Normospermic, Asthenospermic and
Oligospermic subjects, based on the sperm count
and sperm motility. There were 32 normospermic,
51 asthenospermic and 37 oligospermic subjects.
The grouping was based on the WHO guidelines
for semen analysis. The results of clinical
parameters such as sperm motility, viable count
and pH were collected from the clinical proforma.
The semen biochemical parameters investigated
in the present study were prolactin, acid
phosphatase, sorbitol dehydrogenase, glucose,
fructose and pyruvate.
Conclusion: Thus, this study reveals that there
exists a strong relationship between the
biochemical parameters studied and the routine
semen clinical parameters of asthenospermic male
subjects with clinical infertility . Although the
present study could not find such a relationship in
oligospermic subjects with clinical infertility,
additional semen biochemical components such as
citrate, choline and spermine as well as the semen
anti-oxidant system should also be analyzed before
rejecting the hypothesis that a similar association
does not exist in oligospermic males with clinical
infertility.

Biochemical Profile of Cord Blood in Normal Pregnancy and Pregnancy Induced
Hypertension
Dept. of Biochemistry, ASRAM Medical college , Eluru, A.P; Email : [email protected]
Background: Pregnancy induced hypertension
(PIH) is a significany health problem and is the
leading cause of maternal and perinatal mortality
and morbidity. Low birth weight and prematurity
is common in such cases.
Objective: This study was designed to compare
certain biochemical parameters in cord blood of
children born to mothers with PIH and to mothers
with normal pregnancy.
Methods: For this purpose 10ml of cord blood
during delivery was collected from mothers
attending obstetrics department at ASRAM
medical college, Eluru.30 samples were collected
from mothers with uncomplicated pregnancy and
50 samples from the mothers with PIH (maternal
age matched). The 50 samples include group A20 mothers with pre-eclampsia and group B-30
mothers with gestational hypertension The
biochemical parameters measured were glucose,
urea, total proteins, total cholesterol, calcium &
magnesium.
Results:It was observed that all the parameters
except for total cholesterol and calcium were
significantly lower (p<0.00001) in the cord blood
of babies born to mothers with PIH.The total
cholesterol and calcium were significantly higher
in the same cases (p<0.001). On comparison of
parameters of cord blood in babies weighing >
2.5kg in cases vs controls, there was significant
decrease in all the parameters in the former.
Conclusion: So the neonates born to mothers with
PIH must be screened carefully to prevent mortality
and morbidity due to low levels of the important
biochemical parameters like glucose and
magnesium. Neonates weighing >2.5kg are also
at similar risk.

and lipids were measured. Ethical approval and
consent was obtained.
Results: There was no gender difference in weight
or BMI at 6 and 12 yrs. Girls had higher leptin,
and insulin concentrations at 6 yrs (3.1 vs 2.4 and
3.3 vs 3.03 mU/L respectively) and at 12 yrs (3.9
Vs 2.4 and 5.7 vs 4.7 mU/L respectively). BMI,
insulin and leptin concentrations were directly
associated with adiposity at 6 and 12 yrs (p<0.001
for all). Those who were born thin and grew
rapidly from 3 yrs had higher plasma leptin and
insulin concentrations (p=0.001). Higher maternal
weight gain during pregnancy predicted higher
leptin concentration (p=0.04). At 12 yrs, leptin
concentration was directly associated with weight
and inversely with height even after adjusting for
maternal micronutrients, adiposity at birth and
adiposity at 12 yrs (p=0.017 and -0.038 resply).
Higher maternal BMI and erythrocyte folate
concentration predicted higher adiposity and leptin
concentration at 12 yrs (p=0.04 for both).
Conclusion: Maternal micronutrient intake and
high erythrocyte folate concentration in pregnancy
predict higher adiposity, insulin resistance, and
leptin concentration in the offspring. The effect is
stronger at 12 years, suggesting intrauterine
nutritional programming of adiposity

Objective: A comparative study of renal functions
and blood pressure of organized and unorganized
sector of battery workers was conducted to study
the effect of lead exposure and lack of awareness
between the organized and unorganized sector.
Methods: Ninety subjects were selected for the
study of which: Group A had 30 Controls; Group
B had 30 organized battery workers and Group C
had 30 unorganized battery workers. They were
evaluated for their Blood lead level, Zinc
Protoporphyrin and renal functions along with
measurement of blood pressure.
Results: This study shows that there is statistical
significance between Group B and Group C in
116
Blood Lead level (p<0.001), Zinc Protoporphyrin
(p<0.001), Urea (p<0.001) and Uric Acid
(p<0.001)
Conclusions: There was significant difference in
blood lead level, Zinc protoporphyrin and renal
parameters between the two sector though there
was no significant difference between the two in
terms of blood pressure. This difference was
mainly due to the absence of precautionary
principles, proper disposal methods and proper
education to workers in the unorganized sector.
This study signifies the importance of all these
principles.

Background: Excess or decreased secretion of
thyroid hormone leads to hyperthyroidism and
hypothyroidism respectively. Iron is a very critical
mineral for individuals with thyroid disease. Zinc
is one of the most abundant trace elements in the
body. Zinc has close interrelationship with the
endocrine system, it is essential for normal growth,
reproductive function, thyroid function and
glucose metabolism.
Methods: This study was carried out at K.S.Hedge
Medical College Hospital. Individuals were
diagnosed as hypothyroid and normal by ELISA
method .A total of 40 subjects were included in
the studies among them 20 subjects with
hypothyroidism and 20 subjects with normal
thyroid function. Iron was estimated by
Bathophenanthroline method and Zinc by Atomic
absorption spectrophotometer.
Results: Iron and Zinc levels were significantly
decreased in hypothyroidism subjects when
compared to normal subjects.
Conclusion: Our study shows decreased levels of
iron and zinc in hypothyroidism, this may be due
to deficiency in thyroperoxidase activity and
copper level which could interfere with thyroid
hormone synthesis. Hence Iron and zinc
supplements may improve thyroid metabolism in
individuals with hypothyroidism.

Kerala; E-mail: [email protected]
Objective: Extracellular Mg2+ is known to inhibit
agonist-stimulated calcium mobilization from
intracellular calcium stores and exocytosis in
several cell types, possibly by decreasing the free
Ca2+ content of the stores.
Methods: We used Chlortetracycline (CTC), a
Ca2+-sensitive fluorescent probe for cellular
calcium stores, to study the effect of extracellular
magnesium on the quantity of CTC loaded into
cells which in turn, depends on the free Ca2+
content of the stores. CTC was loaded into freshly
isolated, viable, mouse spleen lymphocytes and
human blood neutrophils. Estimation of loaded
CTC was done by digitonin-permeabilization of
CTC-loaded cells, to release the loaded CTC and
comparing the Ca 2+ -induced fluorescence
enhancement of CTC with a standard plot. In the
presence of 1 mM extracellular Ca2+, significant
CTC-loading occurred.
Results: Absence of extracellular Ca2+ (and Mg2+)
during CTC-loading caused a decrease in the
quantity of CTC loaded into cells. Presence of 1
mM extracellular Mg 2+ (in the absence of
extracellular Ca2+) caused a further decrease in
CTC-loading. Extracellular Ca2+ replenishes Ca2+
at the stores. Therefore, in the absence of
extracellular Ca2+ (and Mg2+) the quantity of free
Ca2+ at the stores, decreased and consequently,
CTC-loading into those cells decreased. Further
decrease in CTC-loading in the presence of
extracellular Mg2+ (and absence of extracellular
Ca2+) indicates decreased relative free Ca2+ content
at cellular calcium stores.
Conclusion: These results have general
importance in relation to the modulatory role of
Mg2+ on intracellular Ca2+ signaling processes and
the high Mg2+-induced suppression of several
biological functions of cells

Technical Supervisor, 2Director – Blood Bank Services, Life Line Blood Bank & Research Centre,
Tirunelveli, Tamil Nadu
1
Objective: Iron deficiency is the commonest
cause of anemia worldwide and healthy blood
donors are estimated to lose about 175 to 225 mg
of iron with each donation. The objective of this
study was to determine the serum ferritin levels
among first time and regular male blood donors,
and also to correlate the serum ferritin levels with
the number of donations and hemoglobin levels.
Methods: Hemoglobin levels and serum ferritin
were measured in four groups of donors divided
into I group I (single time donor/year), Group II
119
(twice/year), Group III (thrice/ year) and Group
IV (4 times/ year).
Results: The mean haemoglobin in the first time
donors, II group, III group & IV group were
13.99±1.12, 13.78±1.08, 14.01±1.44 and
13.76±1.14 respectively. The changes in
haemoglobin were not statically significant. The
serum ferritin levels were found to be significantly
lower among the regular donors ie Group IV
(52.0±19.78 ng/ml) compared to first time donors
(129.7±36.66), Group II (112.62±34.89) and
Group III (77.12±26.12). The serum ferritin levels
gradually decrease according to the number of
donations and there was a significant correlation
between frequency of donations and the serum
ferritin level.
Conclusion: This date suggest that the blood
banks must check serum ferritin for all the regular
donors apart form haemoglobin and to advice
donors about iron supplementation accordingly.
This is the responsibility of blood bank towards
these very important persons who are donating life
to others by donating blood.

Objective: Diabetes mellitus has become a global
problem with approximately 221 million people
world wide, and the metabolic disregulations
associated with it causes secondary
pathophysiological changes in multiple organ
system. Kidney is one of the mostly affected organ
which leads to nephropathy. Diabetic nephropathy
has become the leading cause of End Stage Renal
Disease (ESRD), in developing and developed
countries. Cellular magnesium is a critical cofactor in the activity of various enzymes involved
in glucose oxidation like glucokinase,
phosphofructokinase, enolase and also plays a role
in release of insulin. Magnesium deficiency has
been proposed as a novel factor indicated in the
pathogenesis of diabetic complications.
Significant alterations were observed in the serum
magnesium levels of diabetic nephropathy
patients.

Study of Biochemical Markers in Iron Deficiency Anemia
Smita B. Pawar
Lecturer,Department of Biochemistry, M.V.P.’s Medical College Hospital & Research Centre,
Nashik, Maharashtra.
Anemia is the single most common disorder
affecting mankind seen in all parts of the world,
developed as well as developing countries. In India
nearly 70% people are estimated to be iron
deficient. It is misleading to think of anemia as a
single disease with a single cause. The studies of
experimental and human evidences support clear
122
roles for increased oxidative stress due to
susceptibility of lipids of red cell membrane to
peroxidation. A low serum iron alone does not
diagnose iron deficiency, a combination of serum
iron, Total Iron Binding Capacity (TIBC), along
with hemoglobin (Hb) and the trace element zinc
(Zn) are conjunctively essential to diagnose. The
normal adult erythrocytes can resist oxidative
stress by several antioxidant defense systems.
Whereas, the imbalance between oxidative stress
and antioxidant system is present in iron deficient
patients. In light of the several epidemiological,
clinical and laboratory investigations supporting
the role of oxidative stress in anemia, we aimed
to study the alterations in the levels of oxidants
and antioxidants in-patients of iron deficiency
anemia. In abridgement, present study reveals
alterations in the levels of iron, Hb and TIBC, along
with the augmented free radicals and impaired
antioxidant potential.

Background: Pre-eclampsia, a syndrome peculiar endothelial dysfunction and vasoconstriction
to pregnancy is characterized by generalized manifested as proteinuria and increased blood
123
pressure. P selectin, a cell adhesion molecule is
elevated in many inflammatory conditions
including pre-eclampsia. The effect of vitamin E
supplementation on levels of soluble P-selection
in pre-eclampsia has been studied here.
Methods: Soluble P-selectin was measured by
commercially available ELISA kit. Vitamin-E
levels
in
plasma
were
estimated
spectrofluorometrically. Serum and urinary
creatinine as well as urinary protein were
estimated by commercial kits.
Results: In our study the effect of vitamin E (αtocopheryl acetate) supplementation of 400 IU/
day to patients of pre-eclampsia showed
significant decreased levels of soluble P-selectin
by the 2nd week as compared to patients given
placebo (p = 0.005). Vitamin E group of preeclampsia patients had baseline median P-selectin
level of 379 ng/ml, whereas, that of patients
receiving placebo was 363 ng/ml. By the end of
2nd week the values were 302 ng/ml and 380 ng/
ml respectively in both the groups.
Conclusion: Supplementation of 400 IU/day of
vitamin E for two weeks to patients with preeclampsia showed a significant decline in levels
of soluble P-selectin, a marker of inflammation.
In this short period of study no direct correlations
were observed between P-selectin levels and blood

Micronutrient Research Division, National Institute of Nutrition, Jamai-Osmania P.O., Hyderbad-500 007,
Andhra Pradesh, India, Email: [email protected]
Objective: Folic acid is a one-carbon donor
essential for growth and reproduction. Its
deficiency has not been mapped in India due to
lack of field friendly methods of blood collection
and estimation in the laboratory. Conventional
assays like microbiological and competitive
protein binding assay kits are sensitive but require
venous blood sample. In erythrocytes, folate exists
mainly
as
5-methyltetrahydrofolate
polyglutamates and therefore, the objective was
to develop a HPLC method for estimating 5Methyl tetrahydrofolate (5-MTHF) in dried blood
spots (DBS) and to establish as an indicator of
folate status.
Methods: Briefly, the methodology involved
quantitation of 5-MTHF in venous, DBS blood
124
samples and in plasma by HPLC. Stability of
5MTHF in DBS was also tested periodically.
Results: The results indicated that a minimum of
three DBS punches equivalent to 20µl of blood
was required for the analysis. The minimum
detection limit of 5-MTHF was 20 pg .The
recovery of added 5MTHF in the DBS sample was
more than 70%. The inter and intra-assay
variations were found to be less than 10%.
Conclusion: Although there was a good correlation
(r2 = 0.87) between the DBS and blood 5-MTHF levels
estimated by HPLC and folic acid estimated by
commercial kit, folic acid levels were always higher
compared to 5-MTHF. The relation ship between 5MTHF in DBS and folate status is being evaluated.

Miss V. Meenakshi, Dr.S.K. Sen and Dr. Roma Rattan
Background and objective: The data regarding
the effect of age on biochemical variables relating
to bone and mineral metabolism in healthy women
is inadequate. This leads to great hurdle for
initiating preventive measures in age related
osteoporosis in women. Though studies have
examined the role of serum calcium level in
osteoporosis in women, the role of age on serum
calcium and anti resorptive hormone calcitonin
in pre and postmenopausal women has not been
elucidated. Hence the study was designed to
evaluate serum calcium, phosphorous and
calcitonin in the healthy women.
Results: Serum calcium and calcitonin decreased
significantly as compared with control group
(p<0.001). Significant positive correlations were
found between serum calcium and calcitonin
(r=0.887, p<0.01). Serum calcitonin showed a
negative correlation with serum phosphorous (r=

Introduction: In developing countries like India
lead poisoning still occurs.Automobile workers
are prone to long term lead toxicity due to their
routine works such as motor vehicle assembly,
spray painting, burning of petrol, welding, brazing,
battery recharging or replacing and radiator repairing.
Objectives: Occupational lead poisoning is well
documented .No such study has been reported from
this area. Hence the aim of the study is to observe
the lead induced toxic effects among the
automobile workers in the lead based workplaces
from Bijapur city.

Methods: A study on toxic effects of occupational
lead exposue among 27 automobile workers and
25 nonexposed healthy controls from Bijapur city
was carried out. Lead levels in the blood and urine
were analysed by atomic absorption
spectrophotometer and standard assay procedures
were used for other biochemical parameters.The
biochemical parameters studied were serum
bilirubin,total protein,albumin, globulin,A/G
ratio,gamma-glutamyl transferase, alanine
transaminase,aspartate transaminase,alkaline
phosphatase, urea,creatinine and uric acid.
lead levels were significantly increased in the
automobile workers. as compared to nonexposed
healthy controls (P<0.0001). It is also observed
that there is significant change in some liver
function and kidney function tests in automobile
workers.
Conclusion: The study indicates lead toxicity still
persists in automobile workers .The study helps
to create awareness about the toxic effects of lead

Email ID: [email protected]
Objectives: This work was undertaken to study
whether consumption of alcoholic beverage mixed
with soft drinks could reduce the metabolic effect
caused by ethanol.
Methods and results: When 24 hr fasted rats were
intragastrically fed rum (with 40% ethanol) diluted
(1:1) with water, 3.0 ml (0.5 g ethanol) per 100 g
body weight and sacrificed 12 hr later in fasting
condition, exhibited higher levels of triacyl
glycerol, glucose, total cholesterol, high density
lipoprotein (HDL), aspartate amino transferase
(AST), alanine amino transferase (ALT) and
alkaline phosphatase (ALP) in serum, higher
levels of total cholesterol, triacyl glycerol and
thiobarbituric acid reactive substances (TBARS)
in both liver and kidneys, and lower levels of
serum albumin. When fasted rats were fed 3.0 ml
soft drink (0.31 mg caffeine), they showed
increased levels of triacyl glycerol, glucose, ALT
and ALP in the serum, TBARS in liver and kidneys,
triacyl glycerol and total cholesterol in kidneys and
lower levels of serum albumin. Soft drink feeding
did not reduce serum total cholesterol but reduced
HDL levels. Also soft drink did not alter liver
lipids. When a mixture of 1.5 ml diluted rum (0.25
g ethanol) and 1.5 ml soft drink (0.154 mg caffeine)
were fed to the fasted rats, the serum parameters
increased similar to rats fed rum only except that
total cholesterol and HDL cholesterol were
unaltered. TBARS in kidneys and liver were also
increased but triacyl glycerol levels were not
altered.
Conclusion: Thus feeding ethanol with soft drink
does not reduce the metabolic effects of ethanol
but it will prevent ethanol induced serum HDL
cholesterol rise.

Introduction: Gallstone disease is a common
clinical entity affecting the adult population of
both sexes. There are many causes for the disease.
The one main important cause may be the iron
deficiency anemia. So our main study was to
correlate iron deficiency anemia with gallstone
disease.
Methods: 100 patients suffering from
cholelithiaris admitted in our hospital with
confirmed diagnosis by ultra sonography were
included in the study irrespective of their age, sex
and parity. Serum Iron, serum total Cholesterol
and biliary Cholesterol was estimated in all the
patients. Based on serum iron content, the patients
with choleslithiasis were divided into two groups.
Group A contained patients with normal serum
iron and Group B iron deficient patients. Serum
130
and biliary cholesterol contents of both groups
were analyzed and compared with each other.
Results: The mean bile cholesterol level in Group
A was found to be 214.6 mg/dl and in Group B it
was 375.3 mg/dl. The difference in values in both
the groups was found to be statistically extremely
significant (P<0.0001). Iron deficiency has been
shown to alter the activity of several hepatic
enzymes leading to increased gall bladder
cholesterol saturation and promotion of cholesterol
crystal formation.
Conclusion: The present study suggests that iron
deficiency anemia is playing a significant role in
the super saturation of gallbladder bile with
cholesterol and may act as an independent factor
in formation of cholesterol gallstones.

Jyoti Nivas College, Bangalore)
Objective: Water is an essential component for
survival of life on earth. We require water for each
and every activity that we do. The source of lead
in water can be domestic, environmental and
occupational. Keeping in mind the above sources,
it was considered worthwhile to investigate few
water samples from residential areas like
Koramangala and BTM Layout (near to our
college), lakes such as Ulsoor, Madiwala, Agara
etc. and area where there is battery recycle units
such as Tilaknagar for the lead content.
Methods: The estimation of lead content in about
41 water samples was done by Graphite Furnace
Atomic Absorption Spectrometry (GFAAS)
method followed by comparative studies. For
residential areas, the comparison was between
source (treated water/Cauvery water) and kitchen
based on plumbic and non-plumbic supply of
Cauvery water, mixing of Cauvery water with
bore- well water etc. For lake water, the influential
factors were disposal of wastes, immersion of
painted Ganesha idols if any and rain. The amount
of lead was relatively high in the water samples
contaminated through occupational sources as
expected.
Results: The result shows that bore-well water
of Koramangala (especially 7th & 8th Block) has
more lead content than Cauvery water. This may
be due to presence of printing press, automotive
repair shops, industrial machinery etc. around or
plumbic fixtures or fittings in those residences.
Further, mixing of Cauvery water to bore-well
water reduces the lead content. The relatively
greater lead content of Koramangala water tank
may be due to degrading PVC pipes, hard plaster,
lead paints, tile & brick glaze, seals for water mains
etc. The experimental data proves that the borewell and some of the well water are contaminated
with a very little amount of lead in the residential
area of BTM Layout which may be due to
construction of building/flyover, demolition of old
houses, painting, plumbic fixtures and fittings,
pottery, industrial machinery work etc. It is
noteworthy to mention that the lead content in
various water samples of Cauvery water reported
in this project were found to be appreciably small
and it can be regarded as ‘Lead-safe water’. The
significant decrease of lead content in the water of
Ulsoor, Madiwala and Agara lakes from May 2008
to September 2008 may be due to dilution as a
result of heavy rain. This also attributes to the ban
of immersing the painted Ganesha idols in the lakes
of Bangalore city after the holy festival of ‘Ganesha
Chaturthi’ and promoting the eco-Ganesha which
is a great achievement of the entire team of
National Referral Centre for Lead Poisoning in

Awareness about the toxic effects of heavy metals
(LEAD) is still lacking in developing countries.
Lead is one among them, which ranks second in
the Agency for Toxic Substances and Disease
Registry’s top 20 lists of toxic metals. There is
still one source of lead regularly causing poisoning, namely paint, on which this paper focuses.
134
Lead poisoning has been known for centuries.
Childhood poisoning from lead–based paints was
first noted in 1897 in Australia, where children ate
paint chips from porch railings this prompted the
City of Brisbane to pass specific legislation designed to prevent poisoning from lead–based paint.
Lead concentration of blood samples from paint
industries were determined by meta-exchange reagent followed by Anodic Stripping Voltammetry
method. The main aim of this study is to determine the blood lead level of the employees working in Paint industry, from in and around Peenya
industrial area (Bengaluru), to asses the feasibility of using the lead in paints. Some of the paints
being used even now are known to contain this
toxic metal at alarming levels. We have a list of
persons who are quite often suffered from headaches and back aches. Lead is mainly used in
paints for speeding up its drying, & for giving them
desired colors. A wide range of colors contain lead,
for instance, Yellow contains Lead (II) chromate
i.e. PbCrO4, White color contains lead (II) carbonate, PbCO3. The Blood lead level is ranging
from 9.4 to 26.7. Correlating with the values of
control it was found that there is a considerable
rise in the blood lead level. Concluding, the employees in the paint industry have the Blood lead
level at alarming levels.

Department of Biochemistry, PSG Institute of Medical Sciences & Research, Coimbatore-641004.
Background: Myeloperoxidase (MPO), a prooxidant enzyme is released from granules of
activated neutrophils at inflammatory sites. High
levels of MPO have been implicated in the
pathogenesis of CVD. As chronic kidney disease
(CKD) is a risk factor for CVD, we attempted to
estimate levels of MPO in patients with CKD
including end-stage renal disease (ESRD).
Methods: Subjects of this study were classified
into three groups based on GFR which was
calculated using MDRD formula. Group I
consisted of control subjects (n=20) with normal
kidney function and a GFR > 90 ml/min/1.73m2.
Group II and III included patients with CKD.
Group II (n=30) had GFR between 15 and 89 ml/
min/1.73m2 while group III (n=25) had ESRD and
GFR < 15 ml/min/1.73m2. Plasma MPO was
assayed by a spectrophotometric method. Serum
urea and creatinine were estimated on a clinical
chemistry analyzer using standard laboratory
procedures.
Results: Plasma MPO levels progressively
lowered with advancing renal failure. Plasma MPO
levels (U/L) were 62.07 ± 19.76, 46.68 ± 20.03
and 28.73 ± 12.50 (mean ± SD) in groups I, II and
III respectively. MPO levels were significantly
lower in groups II and III when compared with
group I (p<0.05). There was a significant positive
correlation between GFR and MPO (r = +0.458,
p<0.001) and a significant negative correlation
with urea (r = -0.410, p<0.01) and creatinine (r = 0.456, p<0.001).
Conclusion: Contrary to assumption, MPO levels
decline with progression of CKD. Decline in
plasma MPO levels may be due to the inhibitory
effect of uremic toxins on the enzyme.

Correlation of Serum Intact Parathormone Level with Biochemical Parameters in
Various Stages of Chronic Renal Failure Pateints
Bhimappa N.M, Suma M.N and H.S Virupaksha
Background:
The
secondary
hyperparathyroidism is a common, important and
treatable complication of chronic renal
insufficiency (CRI) and end-stage renal disease
(ESRD). Although its exact pathogenesis is not
known, hyperphosphatemia, hypocalcemia,
deficiency of vitamin D, decreased expression of
calcium and vitamin D receptors, and parathyroid
hormone (PTH) resistance have individual roles.
Longstanding secondary hyperparathyroidism
results in osteitis fibrosa cystica (a high turnover
bone lesion) and increases the risks for bone pain
and fractures.
Objectives: 1.To estimate serum intact
parathormone and other biochemical parameters
like serum creatinine, blood urea, serum calcium
and inorganic phosphate in chronic renal failure
patients and healthy volunteers. 2.To compare
serum intact parathormone level with biochemical
parameters in chronic renal failure patients and
healthy volunteers. 3.To find if there is any
correlation between serum intact parathormone
level and biochemical parameters in the study
group.
Methods: 30 patients in each stage of chronic
138
renal failure (totally 150 CRF patients) and 30
healthy controls in the age group of 20-60 years
were taken for the study. Serum intact
parathormone (iPTH) was estimated by
chemilumino-metric assay, serum total calcium by
Arsenazo-III method, serum inorganic phosphate
by ammonium molybdate method, blood urea by
urease method and serum creatinine by Jaffe’s
method. Creatinine clearance was calculated using
Cockcroft and Gault equation.
Results: The level of serum iPTH was significantly
higher in more advanced renal failure, thus
confirming the relationship between severity of
hyperparathyroidism and the degree of renal
impairment. The increased levels of mean serum
iPTH were present even in early renal failure, and
it was related to low mean serum calcium level
and progressive rise of serum inorganic phosphate
from early to advanced renal failure. So serum
iPTH is negatively correlated with creatinine
clearance (GFR) and serum total calcium.
However, serum iPTH is positively correlated with
inorganic phosphate, urea and creatinine. Thus
progressive hypocalcemia and hyperphosphatemia
are the initiating factors for the development of

Objective: Comparison of serum creatinine,
urinary creatinine and urinary beta 2
microglobulin levels as an early marker of subtle
renal dysfunction due to aminoglycoside therapy
in full term sick neonates.
Methods: In this prospective randomised case
control study sixty six full term sick neonates
admitted in NICU of a tertiary hospital from
December 2007 to November 2008 requiring
aminoglycoside treatment and thirty normal
neonates matched appropriately were enrolled in
the study. Apart from routine septic profile, the
parameters to assess renal function included serum
creatinine, urinary creatinine and urinary Beta 2
microglobulin which were estimated on day of
admission and on Day 3, Day 7. The investigations
done in controls were urinary Beta 2
microglobulin on Day 1 and Day3 of life. All sixty
six full term sick neonates were administered
cefotaxime and gentamicin or amikacin alternately
for duration of minimum seven days.
Results: In our study, the percentage of renal
dysfunction diagnosed by serum creatinine was
28% and by urinary beta 2 microglobulin was 68%.
This signifies that 40% of the neonates with subtle
renal dysfunction would be missed if traditional
tests are used in diagnosis. It also revealed that
though Beta 2 microglobinuria is an extremely
sensitive indicator of proximal tubular dysfunction,
it was a relatively insensitive test to diagnose
aminoglycoside nephrotoxicity due to coexistence
of underlying clinical conditions in sick neonates.
Conclusion: Beta 2 microglobinuria is a sensitive
and early indicator of proximal tubular function
but its clinical utility in diagnosis of
aminoglycoside nephrotoxicity is limited due to
presence of multiple confounding factors.

Methods: 60 cases of hypertensive patients were
selected who were negative for albustix in urine
and were assessed for incidence of
microalbuninuria with reference to their habits of
smoking and alcoholism. Out of 60 hypertensive
patients 46 (77%) were found to have
microalbuminuria.
Prevalence
of
microalbuminuria in males and females were found
139
to be 77% and 75% respectively in those 46 cases.
48 normal healthy individuals who were not
hypertensive and were non-alcholics and nonsmokers constituted the control. The twenty-four
hours urine samples were collected and stored with
preservative. The urinary microalbumin was
estimated by using pyrogallol method (Pointe
scientific,inc..USA) Microaluminuria was also
calculated in terms of albumin/creatinine ratio
(mg/g).
Results: In the present study microalbuminuria
in controls and hypertensives was found to be
19.02mg/day±5.25 and 77.08mg/day±37.35. The
increased microalbuminuria in hypertensives was
statistically significant (p<0.001). Albumin
creatinine ratio in controls and cases were found
to be 14.44 mg/g±4.62 and 57.62mg/g±30.66
respectively. The increase of albumin creatinine
ratio in hypertensives was also found to be
statistically significant (p<0.001). Prevalence of
microalbuminuria in nonsmokers and nonalcoholic
hypertensives was found to be 14%. However the
prevalence in alcoholics, smokers and both smoker
& alcoholic groups were found to be 22%, 32%
and 32% respectively. The mean urinary
microalbumin level in smokers, alcoholics,
smokers&alcoholic and nonsmoker &
nonalcoholic groups were found to be 97.22mg/
day, 89.66 mg/day, 122.66 mg/day and 80.5 mg/
day respectively. The alcoholics and smokers
exhibited statistically significant (p<0..001) higher
level for microalbumin as compared to other
groups. These findings suggest both smoking and
alcholism adversely affects the renal functions.
Conclusion: Thus it becomes immensely
important in respect of therapeutic implementation
and educating the hypertensives regarding the ill
effects of smoking and alcoholism

Department Of Biochemistry, J.S.S Medical College, Mysore, Karnataka; Email
Background: Chronic kidney disease is
characterized by progressive loss of renal function.
Cardiovascular disease is the leading cause for
morbidity and mortality in these patients.
Lipoprotein(a) [Lp(a)] is a cholesterol rich particle
existing in the human plasma. In chronic kidney
disease patients, lipoprotein(a) level is increased.
Increased lipoprotein(a) level is risk for
cardiovascular disease.
Objectives: 1.To estimate serum lipoprotein(a) in
chronic kidney disease patients. 2.To estimate total
cholesterol, HDL-Cholesterol, LDL-Cholesterol
and triglyceride levels. 3. To compare the above
with age and sex matched healthy controls. 4. To
study if there is any correlation between
140
lipoprotein(a) and cholesterol, triglyceride, LDLCholesterol and HDL-Cholesterol.
Methods: The study group included 30 patients
diagnosed as chronic kidney disease patients and
30 healthy controls. Serum lipoprotein(a) was
estimated. Total Cholesterol, Triglyceride, LDLCholesterol, HDL-Cholesterol were correlated
with lipoprotein(a) levels.
Results and Discussions: There was significant
increase in lipoprotein(a) level in patients with
chronic kidney disease when compared to controls.
Increase in lipoprotein(a) level was statistically
significant. Increased Lp(a) level along with
increased triglyceride, LDL-Cholesterol could lead
to the accelerated tendency of atherosclerosis and
other cardiovascular abnormalities in these patients.

Evaluation of Urinary Protein Bound Sialic Acid and Protein Carbonyl content as
the Prognostic Markers of Nephrotic Syndrome in Pediatric Age Group
Niranjan.G, Koner B.C and Bhat .V
Department of Biochemistry and pediatric , JIPMER; Email ID: [email protected]
Introduction: Nephrotic syndrome (NS) is a
common disorder affecting mainly the pediatric
age group, 90% of the NS cases are idiopathic
which can be classified as steroid sensitive (SS),
steroid dependent (SD) and steroid resistant (SR)
cases depending on response to treatment with
steroids. There is no way to predict at the onset
which cases are going to be SS, SD or SR cases.
Hence the present study was designed to find out
if urinary protein bound sialic acid (UPBSA) and
urine protein carbonyl content (UPCC) differ in
SS, SD or SR cases of NS and also to find out
estimation of these parameters before starting the
treatment can predict the prognosis of these cases.
Methods: 70 NS cases were enrolled in the study.
UPBSA and UPCC were estimated by
modifications in Aminoff’s and Levine’smethods
respectively in all the cases before starting the
steroid treatment. Later all the cases were followed
up out of which 47 cases became SS also we also
got 15 SD and 8 SR cases.
Results: Both UPBSA and UPCC s were
significantly low in SS compared to SD and SR
cases. ROC showed a cutoff limit of 2.74 µgm/mg
for UPBSA and 7.02 n moles/mg protein for UPCC
to predict SD/SR cases of NS.
Conclusion: Urinary protein bound sialic acid and
urinary protein carbonyl content can be used as a
marker to predict SS, SR and SD cases of NS.

identified with an abnormal TSH. This small study
reveals that severe hypothyroidism may
masquerade as renal impairment. Mildly elevated
creatinine showed TSH values well above 300
mIU/ml. The identification and treatment soon
reduced the renal impairment in terms of lowered
serum creatinine and urine protein creatinine ratio
along with improvement in the thyroid status.
Conclusion: TSH should be considered when
evaluating patients of renal impairment of
unknown etiology. The cause of renal failure in
hypothyroidism may be explained by (i) decreased
renal plasma flow due to a hypodynamic state and
in severe cases can be (ii) secondary to

Objective: Serum creatinine (SCr) is a traditional
parameter which is widely used for the assessment
of renal function. Serum cystatin C (SCys) is an
emerging parameter which has been proposed as
an early indicator renal dysfunction. This study
was carried out to compare the performance
characteristics of these two parameters in renal
transplant recipients (RTR).
Methods: SCr and SCys were estimated using
standard laboratory techniques in 30 RTR.
Glomerular filtration rate (GFR) was calculated
143
from SCr using MDRD formula and from SCys
using the Le Bricon formula.
The calculated GFR values are also indicative of
mild renal failure.
Results: Values are expressed as mean ± S.D. The
SCr level was 1.257 ± 0.316 mg/dL which is
indicative of normal renal function. In contrast,
the SCys level was 1.401 ± 0.256 mg/L which is
higher than the reference range (0.52 – 1.1 mg/
L). The calculated GFR based on MDRD was
65.46 ± 16.37 ml/min/1.73m2 while the GFR based
on Le Bricon was 61.59 ± 11.12 ml/min/1.73m2.
Conclusion: Creatinine is removed not only by
glomerular filtration but also by tubular secretion.
Cystatin C on the other hand is removed
exclusively by glomerular filtration. Levels of
SCys therefore rise with even mild decreases in
GFR. To conclude SCys is a more sensitive and
reliable marker of mildly impaired renal function
in renal transplant recipients when compared with SCr.

Objective - Birth asphyxia occurs when a baby
does not receive enough oxygen before, during or
just after birth. Target organs of perinatal asphyxia
144
are the kidneys, lungs, brain, liver, gut and bone
marrow. The most frequent abnormalities involve
Kidneys (50%), CNS (28%), lungs (23%) and so
on. High blood urea and serum creatinine values
are associated with renal failure. We performed
this study to determine the incidence of renal
failure in birth asphyxia and to correlate the
severity of renal failure with asphyxia.
By –:
Estimating serum creatinine level in neonatal
asphyxia, : Estimation of blood urea nitrogen, :
Determination of blood urea nitrogen / creatinine
ratio on I, III & VII day of life, : And total urine
output within 24 hrs.
Methods- The study included 50 asphyxiated and
25 healthy neonates. Renal functions were
assessed using urinary output and biochemical
parameters such as blood urea by Urease
GLDH method and serum creatinine by Jaffes
kinetic method.
Results- Blood urea and serum creatinine were
significantly higher in asphyxiated babies
compared to control groups (p<0.001). Blood Urea
nitrogen / Creatinine ratio was significantly higher
in asphyxiated babies compared to control groups
(p<0.001) on day 3 but insignificant on day 1.
There was no significant difference in the urine
output in the control and the study group. Majority
of asphyxiated neonates had non-oliguric renal
failure.
Conclusion- We conclude that renal failure is a
significant problem in asphyxiated neonates. A
high level of Urea & Creatinine on III rd day of
study is associated with renal failure in asphyxia.
Despite tremendous advancements in medicine,
treatment of ARF has remained essentially
supportive. Birth asphyxia is still common, more
so in developing countries where obstetric and new
born resuscitation facilities are not universally
available yet. Combination of dehydration, shock,
sepsis and nephrotoxic drugs is not an uncommon
situation in NICU.These lead to high incidences
of neonatal renal failure. They are often reversible
if identified and managed in time.

Background: Organic matrix of calcium oxalate
stones
consists
of
protein,
lipid,
glycosaminoglycans etc. It is suggested that
presence of these biomolecules in stone organic
matrix is related with the formation of renal
calculi. There are many proteins which are
reported to exhibit inhibitory or stimulatory
activity against kidney stone formation, for
example Tamm-horsfall protein, osteopontin etc.
However, only few studies have been done on the
activity of lipid biomolecules on kidney stone
formation.
Methods: Surgically removed calcium oxalate
stones were first confirmed by FTIR analysis,
washed with 0.15M NaCl and then pulverized.
Powdered calcium oxalate was extracted with ice
cold chloroform: methanol: 0.05M Tris HCl pH7.4
(2:1:1); using sonication at 4ÚC. Upper and lower
phases were removed separately and pooled as
aqueous and organic substances after
centrifugation. Organic phase was extracted with
ethanol: ether (3:1) and then centrifuged.

Results: The lower volumes of complexed lipids
showed inhibitory activity whereas stimulatory
activity was observed with their higher volumes
when it comes to the nucleation of CaOx crystals.
However, complexed lipids present in the organic
matrix of CaOx kidney stones exhibited inhibitory
activity against the CaOx crystal growth assay

Prevalence and Characterization of Renal Tubular Acidosis in Patients with
Myalgias, Osteoporosis and Mild Arthritis.
Rachel Jacob
Department of Biochemistry, NIMS, Hyderabad.
Background: Overt metabolic acidosis is
undoubtedly associated with metabolic bone
disease, but the prevalence of metabolic acidosis
in mild osteoporosis and arthritis is uncertain.
Chronic metabolic acidosis may also manifest
with musculoskeletal symptoms of varying
degrees.
Objective: It was purposed to identify the
prevalence of renal tubular acidosis in patients
suffering with chronic myalgias, mild osteoporosis
and mild arthritis.
Methods: Review of hospital data 2001-2008,
revealed 52 patients with complaints of myalgia,
muscle weakness, joint pains and/or arthritis.
Ammonium chloride load test (0.1g/kg body
weight) was done to establish renal acidification
defect. Screening for immune-mediated disorders
was done. Blood and urine chemistries, arterial
blood gas analysis were done to identify
electrolyte imbalance. Osteoporosis was assessed
by nuclear scan.
Results: Thirty-four (65%) cases were identified
to have an acidification defect(M-14, F-20), 31 had
distal tubular acidosis (dRTA) and 3 of proximal
RTA. Forty percent of the women were in the
menopausal and post-menopausal phase.
Neuromuscular weakness associated with
hypokalemia was evident in 76% while
osteoporosis and bone disease was confirmed in
74%. Metabolic acidosis was seen in 88% with
low serum bicarbonate and normal to mild acidosis
was noted in 6 cases. One case each of Sjogrens,
Vitamin-D resistant rickets, inflammatory arthritis,
renal calculus and renal osteodystrophy were
identified.
Conclusion: RTA can be a major cause of myalgias
and joint pains with or without weakness. Women
around the menopausal period need to be evaluated
for RTA. Normal blood pH or mild acidosis
warrants further investigation to avoid missing
incomplete dRTA.

Background: Non enzymatic glycation, the
reaction of glucose and other reducing sugars with
protein, reversibly produces amadori products and
over a long period irreversibly advanced glycation
end product (AGE) are formed. These AGE
products contribute to the pathogenesis of diabetic
complication. Recently in vitro AGE formation
from glucose and albumin were found to be due
in part to the oxidants.
Objective: The aim of our study is to investigate
the antioxidant property of creatinine and uric acid
and the inhibition potency of the antioxidant on
the formation of AGE products in vitro. In vitro
glycation was studied with bovine albumin as the
model protein.
Advanced glycation products were quantified by
measuring the protein carbonyl content by Levin
et al method. Uric acid and creatinine were used
as potent inhibition of glycation mixture. Using
the same range of concentration used for inhibition
of AGE products, uric acid and creatinine were
assessed for antioxidant property by reducing
power assay. Both antioxidant activity and
inhibition of glycation in vitro show a positive
correlation.
Results: In our study we found that uric acid and
creatinine decreased the amount of AGE products

INDIA. Email: [email protected]
Background: ‘Save the Kidney’ was theme for
2004 given by WHO with the assurance that every
hypertensive patient be screened for nephropathy.
Microalbuminuria is associated with glomerular
damage and endothelial dysfunction which leads
to development of nephropathy. Nephropathy, if

left untreated can lead to serious complication such
as kidney failure because albumin molecules are
relatively small; it is often among the first proteins
to enter the urine after the glomeruli damage. So,
even minor kidney dysfunction should be detected
with proper diagnosis of microalbuminuria.
Objective: In our study the effect of hypertension
on the incidence and frequency of
microalbuminuria has been evaluated and
correlated with other renal biochemical
parameters.
Methods: 60 patients of hypertension of both
sexes between 27 to 76 years of age were studied
and 20 controls were also included Blood tests
(sugar, urea, creatinine and total cholesterol) and
urine analysis (protein, sugar and microalbumin
was done.
Results: Urinary microalbumin was significantly
raised in cases of hypertension. A positive
correlation was found between the age and urinary
microalbumin levels and serum cholesterol and
urinary microalbumin. Similarly creatinine and
BUN was raised although within normal range in
cases of hypertension with raised urinary
microalbumin. It is apparent that the earliest sign
of nephropathy in hypertensive patients is
microalbuminuria. It is conclude that Nephropathy
is a common complication of hypertension and rise
in the levels of urinary microalbumin is an early
indicator for the development of nephropathy.

Objective: Nephrotic syndrome or nephrosis is a
group of symptoms of kidney malfunction with
typical clinical features associated with plasma
protein changes such as hypoalbunemia,
hyperalbuminuria, hyperlipidemia, hyperlipiduria
and edema. There is a geographical variation in
the prevalence and pattern of this disease. This
disease is mainly seen in children and young
adults. Earlier studies conducted revealed a high
prevalence of this disease in children in India
Subcontinent and South East Asia. Protein
electrophoresis is a good screening procedure to
evaluate the major serum proteins. This method
is extensively used as a diagnostic and prognostic
tool for facilitating diagnosis of various diseases,
especially nephritic syndrome.many diseases. In
this study the serum protein electrophoresis pattern
is evaluated using Agarose Gel electrophoresis
(Ready to use kit Hydragel Protein kit Supplied
by M/S Sebia, France).
Methods: A total of 20 serum samples of patients
with nephrotic syndrome and serum samples of
20 healthy age and sex matched controls were
included for the study. Serum total protein (Biuret
method), serum albumin (BCP Dye-binding
method) and serum cholesterol (Enzymatic HOD
– PAP method) were also estimated. Urine samples
of all the subjects were collected and analysed.
Results: There was a significant increase in serum

Manjunatha G.J and Vijay S. Bhat
Manipal Hospital, Old Airport road, Bangalore-560017
Background: CKD is a unique condition in that
exceedingly high incidence of insulin resistance,
which in turn associated with enhanced
cardiovascular events, is paradoxically associated
with elevated adiponectin.
Objective: Adiponectin, a 30kD collagen like
protein exclusively produced by adipocytes,
possessing anti inflammatory properties, a marker
of oxidative stress was taken up in this study which
consisted of patients in different stages of renal
disease. A correlative study of adiponectin with
markers of inflammation (CRP) and renal function
(Cystatin –C, eGFR & ACR) was done.
Results: There was no correlation between CRP
and adiponectin levels (p =0.267), There was an
inverse relationship between eGFR and
adiponectin (ìg/ml log transformed) (r = -0.364,
P < 0.001) and a direct relationship with ACR and
log transformed adiponectin(r = 0.42, p=0.006).
Cystatin–C was significantly higher in renal
transplant patients than in normal, independently

The Effects of Kidney Function and Transplantation on Plasma Electrolytes,
Albumin and Cardiovascular Risk
Thompson, M.J.W.1 and Ray, U.1,2
University of Tasmania, Hobart, Australia1; Royal Hobart Hospital Hobart, Tasmania, Australia2.
Background: Chronic kidney disease (CKD) is
an increasingly common disease that greatly
increases risk of cardiovascular disease (CVD),
particularly coronary artery disease. Risk of CVD
is directly proportional to degree of kidney
impairment and greatest in end stage kidney
disease (ESKD). As CKD progresses, the effect
of traditional risk factors such hyperlipidemia on
cardiovascular mortality decreases and the effects
of novel risk factors such as vascular ossification
and hypoalbuminemia increases. Accordingly,
clinical trials using traditional interventions such
as statins have thus far failed to show a benefit.
Optimal treatment for ESKD is kidney

transplantation, which is known to improve
survival over maintenance dialysis.
Objective: To examine the effect of kidney
transplantation on plasma electrolytes & albumin
to see whether this contributes to the survival
advantage of kidney transplant recipients over
those on maintenance dialysis.
Methods: We conducted a retrospective cohort
study of 48 patients (M = 29, F = 19; Age = 2484) receiving a kidney transplant at the Royal
Hobart Hospital within the last 10 years.
Biochemical profiles immediately pre- and posttransplantation and over the longer term were
analysed.
Results: Plasma phosphate, magnesium and
potassium increased in direct proportion to degree
of kidney impairment (all p<0.0001), whereas
albumin and calcium decreased (p<0.0001).
Kidney transplantation resulted in an immediate
reduction in phosphate, magnesium (both
p<0.0001) and potassium (p= 0.014). These
reductions were maintained long term (all
p<0.0001). There was no immediate change in
calcium (p=0.34) or albumin (p=0.42), however
over a longer time period both increased
significantly over pre-transplantation levels
(p<0.0001).

Background: Study of urolithiasis is important
in understanding the pathogenesis and medical
management of calculus disease. Quantitative
analysis of 50 urinary stones (30 kidney, 9 bladder,
11 ureter) collected from different hospitals of
Gwalior region was carried out.
Objective: To study morphological characteristics
of urinary stones. Oxalic acid, uric acid, calcium,
and inorganic phosphate were also estimated.
Results: The incidence of urinary stones was
found as kidney > bladder >ureter The incidence
of kidney stones was higher in age of 30-40 than
ureter and bladder. Oxalic acid was found as a
major component in all the stones analysed.
Calcium content of stones was kidney > ureter >
bladder. Uric acid was seen in stones ureter >
bladder > kidney. Inorganic phosphorus content
of stone was kidney > bladder > ureter.
Hyperoxaluria, hyperuricemia, hyperphosphaturia,
hypercalciuria were found in some cases. The high
incidence of calcium and oxalate urinary stones in
this region may be due to high consumption of
vegetables rich in calcium and oxalate. Other
factors which may be responsible for urolithiasis
are water intake, climatic conditions, dehydration,
metabolic abnormalities, urinary tract infections

Objectives:Cardiovascularcomplications (CVC)
are predominant problems both in ageing and
diabetes. The present study focuses on the effect
of human ageing and diabetes , with special
reference to serum level lipid profile during
cardiovascular complications in two age groups
namely, 45 ± 5 years and 65± 5years independent
of obesity, hypertension and nephropathy.
Methods: The parameters include; estimation of
serum total cholesterol, serum triglycerides , HDLC, LDL-C and VLDL-C .
Results:Results show that the change in the levels
of lipid parameters follow a near similar trend in
the two non-diabetic age groups with
cardiovascular complications. Except the HDL-C
decline, total cholesterol, LDL-C, VLDL and
triglycerides increase. In diabetes, however, the
said lipid parameters are not so similarly affected
in the stated age subjects. One interesting
observation is the near similar levels of lipid
parameters found in diabetic 45 ± 5 yr and nondiabetic 65 ± 5 yr age groups with Cardiovascular
complications.
Conclusion:It is, therefore, suggested that diabetes
accelerates age related disturbances in the lipid

Introduction: To provide the best treatment for
coronary heart disease (CHD) patients, one must
go beyond LDL cholesterol to detect factors
contributing to CHD risk or existing CHD. These
158
emerging risk factors appear to identify individuals
at increased CHD risk and the assessment of these
can modulate clinical judgment when making
therapeutic decisions. This study focus on five

(TAS), homocysteine and Fibrinogen.
Methods: Study was carried out by taking 396
subjects, out of which 127 control cases were
selected by screening with lipid profile, treadmill
test (TMT) and fasting blood sugar, to ensure that
they are not suffering from hyperlipidemias,
dyslipidemia or diabetes. 269 angiographically
proven CAD cases were selected for the present
work. Lp(a), hs-CRP, TAS was estimated using
Hitachi 912 analyser. The levels of Homocysteine
were estimated by EIA method using Bio-Rad kit
in Bio-Rad CODA analyzer. The levels of
fibrinogen were estimated by Clauss method in
Sysmax Autoanalyzer.
Results: Recent markers Lp (a), hs-CRP,
homocysteine and fibrinogen levels were
significantly increased in CAD cases. TAS was
significantly decreased in the CAD group. The
homocysteine level was significantly increased
(p<0.001) in the present study. Oxidative indices
like total antioxidant capacity was found decrease
Conclusions: The statistical analysis of the study
shows that these markers are more closely
associated with atherosclerosis. Recent cardiac
markers i.e. homocysteine and Lp (a) showed no
significant correlation in our study with other
parameters therefore they may be considered as
independent markers. Lp (a) is closely associated
with LDL and low values of HDL-C so it could
also be considered as independent marker for CAD
assessment. The inflammatory markers hs-CRP
and fibrinogen emerged as a marker of choice to
diagnose atherosclerosis. Many previous studies
also showed that persistent hyperglycemia can
cause oxidative stress followed by release of
inflammatory markers and then formation of
atheroma in vessels. The screening with the
emerging risk markers is helpful in risk assessment
of coronary Heart disease. This additional
diagnostic information can assist in the prevention
or early diagnosis and treatment of atherosclerotic

Influence of Atherosclerosis and Exercise on Arterial Lipoprotein
Lipase Activity in Pigs
Shakti Aggarwal, Theodore W. Zderic, Perminder Gulani and Marc T. Hamilton,
University of Missouri-Columbia, USA.
Objective: Lipoprotein lipase (LPL) has
repeatedly been identified as one of the major
susceptibility genes for human coronary artery
disease. However, the functional enzyme activity
has heretofore never been quantified in arteries
with respect to either vascular disease or exercise
training. We have overcome prior experimental
limitations by utilizing a porcine model of
atherosclerosis, where the endothelium from large
160
arterial samples could be obtained in conjunction
with modifications in the LPL assay to improve
accuracy. The primary purpose was to determine
the effects of exercise training on arterial LPL
activity in a porcine model of atherosclerosis.
Methods: Heparin releasable LPL (HR-LPL)
activity was measured in approximately 5.2 cm2
of the thoracic aorta, skeletal muscle and adipose
tissue. In keeping with the purpose, a pig strain
with familial hypercholesterolemia (FH) was run
trained for ~5 months and compared to controls
fed an identical diet (N=13 run trained and N=12
untrained). As a basis of comparison to generally
healthy pigs, LPL was measured in another strain
of pigs with substantially lower plasma cholesterol
(Yucutan).
19±3 mU/mg total protein; p<0.05). This two-fold
training effect for artery HR-LPL was evident in
both males and females. In contrast to this, neither
skeletal muscle, nor adipose HR-LPL activity was
altered by the exercise training. Paradoxically,
arterial HR-LPL activity was 13.7 fold greater in
FH pigs (21.3±4.6 mU/mg), compared to the
Yucatan pigs (1.6±0.2 mU/mg).
Results: There was about twice as much arterial Conclusion:: Exercise run training increased
HR-LPL activity in FH pigs after the exercise arterial HR-LPL activity in a porcine model of
training compared to sedentary controls (40±4 vs. lipoprotein-induced atherosclerosis.

Objective: To study whether genetic
polymorphism in ApoA1 gene (G-75A and
C+83T) could be playing a role in occurrence of
Myocardial Infarction.
Methods: Study group consisted of 100 subjects
(50 diagnosed MI patients, 50 healthy subjects).
S. Apolipoprotein A1 and S. Apolipoprotein B
were estimated by immunoturbidometric assay on
SYNCHRON CX9 (BECKMAN). Extracted
162
DNA from blood sample was amplified by PCR,
which was digested overnight with MspI
restriction enzyme. Digested products obtained
were run on 8% Polyacrylamide gel and
Restriction fragment length polymorphism was
studied by gel documentation system.
Results: S. ApoA1 levels were significantly higher
in control group compared to study group (100.80
±7.06mg/dl and 72.56±9.86mg/dl respectively;
p<0.0001) and S. Apo B levels were significantly
higher in study group compared to control group
(97.45 ± 9.04mg/dl and 72.12 ± 11.32mg/dl
respectively; p<0.0001). The frequency of the G
allele at -75bp site was higher in the study group
(79%) compared to controls (58%).Genotypic
distribution in study group was [GG
(58%),GA(42%)] compared to controls
[GG(16%),GA(84%)] with p<0.0001. The
frequency of the T allele at +83bp site was higher
in the study group(56%) compared to
controls(32%).Genotypic distribution in study
group [CC(24%),CT(40%),TT(36%)] was
different as compared to controls
[CC(36%),CT64%)] with p<0.0001.
Conclusion: In Apolipoprotein A1 gene, G at 75bp upstream from start of transcription and T at
+83bp site in the first intron may be susceptibility
alleles for myocardial infarction in Indian
Population. However, ours being a pilot study,
more studies with larger sample size are needed to

*SRTR medical College,Ambajogai,Dist Beed, Maharashtra.**B.J.Medical College,Pune.
Objective: Preeclampsia is the main cause of
maternal and perinatal mortality and contributes
8% of maternal deaths in India. In women with
preeclampsia there is dyslipidemia and decreased
antioxidant activity. The present study was
undertaken to evaluate the lipid (cholesterol& TG)
levels and serum ascorbic acid level in
preeclampsia.
Methods: For the present study, we have selected
40 normotensive pregnant women of age group
20-35 years comprising Group I and 40 preeclamptic women of same age group comprising
Group II. Serum samples were analysed for serum
total cholesterol, triglycerides and serum ascorbic
acid levels.
Results: A significant increase in serum total
cholesterol and serum triglyceride levels were
found in Group II as compared to Group I while
serum ascorbic acid levels were decreased
significantly in Group II as compared to Group I.
Conclusion: In preeclampsia there is
dyslipidemia. The hypertriglyceridemia may lead
to increased endothelial triglyceride accumulation
that in turn may result in endothelial dysfunction
probably by promoting oxidative stress in arterial
wall. The antoxidant nutrient like ascorbic acid
may be utilised to greater extent to counteract free
radical mediated cell disturbances resulting in
reduction in antioxidant nutrient level in serum.

*SRM medical college Potheri, **SRMC Porur
Objective: Hypertension and obesity is becoming
a common health problem worldwide. It is linked
with vascular inflammation, lipotoxicity and
oxidative stress that results in vascular end organ
damage. Aim of the study is to measure the
inflammatory markers of vascular endothelium,
namely hs-CRP and urinary microalbumin in
obese and non-obese hypertensives, that predicts
the future cardiovascular events.
Methods: The study was conducted among 120
subjects who were non-smokers and non-alcoholic
of age 40 – 60 yrs with hypertension. Patients were
divided into three stages of hypertension according
to JNC-6. Fasting blood samples were collected
to estimate glucose, lipid profile, blood urea
nitrogen, creatinine, hs-CRP, TC, DC. Overnight
spot urinary sample was collected to measure
166
urinary microalbumin. Fundus changes were
observed to assess the vascular endothelial
damage.
Results: The mean of hs-CRP and microalbumin
was significantly high in obese than non-obese
hypertensive group (p= 0.000). There was a strong
correlation between hypertensive retinal changes
and microalbuminuria (P < 0.0001 ). Tests of
accuracy for retinopathy as a predictor of
microalbuminuria showed a sensitivity of 72% and
specificity of 81%.
Conclusion: hs-CRP and urinary microalbumin
are early markers of endothelial dysfunction which
can predict cardiovascular risk in hypertensives.
Retinal changes have moderate accuracy in
predicting microalbuminuria

significantly elevated by 49.2%, (P=0.001), 54.3%
(P=0.001), 18.9% (P=0.012) respectively in
hypertensive subjects. Significant negative
correlation was observed of sP-selectin (spearman
rank correlation coefficient (rs) =−0.345, p=0.027)
and sPECAM-1 (rs =−0.446, p=0.003) with age in
hypertension group.
Conclusion: Hypertension may increase
expression of certain CAMs while younger
hypertensives in addition are also at increased risk
of atherothrombosis.

and 3 Biochemistry Department, IMS B.H.U. Varanasi. Email: [email protected]
Introduction: It has been predicted that by 2020
there would be a 111% increase in cardiovascular
deaths in India due to hypertension resulting in
cardiovascular diseases (CVD). Mild elevations
in serum homocysteine may contribute to
elevations in blood pressure which may be one of
the important causes for CVD. Controversy
remains as to whether the relation between
homocysteine and CVD is causal or not? Our study
comprises the relationship of homocysteine with
blood pressure.
Methods: Our study consists of 40 subjects
diagnosed as hypertensive for the first time and
20 controls with normal Blood pressure taken
randomly from cardiology OPD of our hospital.
Most of the patients of both sexes were from
Eastern Uttar Pradesh (Varanasi) and from Bihar.
They were in the range of 25 to 60 years of age.
Levels of Homocysteine were measured in serum
by ELISA technique and Blood pressure along with
clinical history was observed separately for all
subjects.
Results: It was observed that Homocysteine was
significantly elevated in hypertensive patients as
compared to controls with p<0.001. It also bears a
high degree of correlation with systolic blood
pressure. It was also observed that the sex along
with age and life style plays a very important role
for our study.
Conclusion: This study shows that homocysteine
is significantly elevated in patients of hypertension
and concludes that in every CVD patients
homocysteine plays a very important role.

Introduction: Alterations in the lipid profiles have
been reported in patients of acute myocardial
infarction (AMI). These reports however are
controversial- some claim reduction while others
report increase in different parameters of lipid
profile. The objective of the study was to evaluate
the changes that occur in lipid profile in AMI,
including the ratios of total cholesterol / HDL
cholesterol, and LDL cholesterol / HDL
cholesterol.
Methods: This study was conducted in 25 patients
of AMI admitted at Government General Hospital,
Vijayawada. Fasting(14 hr) blood samples were
collected at 24 hours, 48 hours and 5 days predischarge, and serum was analyzed for TG, total
cholesterol, HDL cholesterol, VLDL and LDL
cholesterol were calculated using Friedwald
formula.
170
Results: There was no significant change in the
serum total cholesterol at 24 hours, 48 hours and
5 days predischarge. HDL cholesterol marginally
fell at 48 hours; VLDL showed slight increase at
48 hours and 5th day predischarge. Changes in
LDL cholesterol were negligible. Serum TG
showed an increasing trend after MI at 48 hours
and 5th day predischarge. An elevation in the
ratios of total cholesterol / HDL cholesterol was
observed at 48 hours and 5th day predischarge.
However, LDL / HDL ratio remained almost the
same.
Conclusion: It is concluded that although there
are variations (24 hours, 48hours and 5th day predischarge) in the lipid profile in the patients of
AMI, the ideal period for the estimation of lipid
profile appears to be within 24 hours of the acute
episode.

Professor, Dept of Biochemistry, Fr Muller medical college,Mangalore. E mail :
[email protected]
Background: Coronary artery disease (CAD) is
the most common type of heart disease..
Hyperlipidemia is considered as one of the risk
factors in the development of coronary artery
disease .(CAD) . The National Cholesterol
education program (NCEP) has suggested normal
reference ranges for lipid profile. However various
epidemiological studies done in different parts of
India show different cut off levels suggesting that
the lipid levels could be influenced by various
geographic factors .These studies point out the
need to survey the population region wise and to
establish normal reference ranges in them.
healthy controls of age groups between 21-75 yrs
was assayed in the laboratory using autoanalyser
by the recommended methods .The results were
then categorized age wise under four groups .
Stastical analysis was done by student t test and
ANOVA (analysis of variance) methods.
Objectives: To assess the average lipid levels in
the healthy adults of Mangalore city and to set up
age and sex matched reference ranges in the
population.
Conclusion: Screening for dyslipidemia in all
adults above 20 years and Health education
regarding modification of life style and dietary
habits would be useful to control hyperlipidemia.
Results: The overall lipid level was found to be
on the higher side of the normal reference level in
the study population. In males lipid levels were
found to be higher in 36-50 yr age group and in
females in the postmenopausal group who were
beyond 50 yrsof age.

Sinha Institute of Medical Scince and Technology, 288 Kendua Main Road, Baishnabghata, Garia,
Objectives: We have reported before that the
increase of nitric oxide synthesis in leucocytes in
the circulation resulted in the synthesis of
interferon-á (IFN-á), a well known cytokine. It
was also found that IFN-á was a potent inhibitor
of platelet aggregation (minimal inhibitory dose
≈10nM) similar to that of prostacyclin (PGI2),
currently believed to be the most powerful inhibitor
of platelet aggregation. However unlike PGI2, IFNá was a potent thrombolytic agent that dissoluted
clotted plasma in vitro and fibrinolysed coronary
171
thrombosis in animal model. We investigated the
role of IFN-á in the pathophysiology of the
development of AIHD.
Methods: Fifty patients with acute myocardial
infarction (35 male, 15 female, between 50-68 year
old who were admitted in ICU, Calcutta Medical
College, Calcutta) and 50 age and sex matched
normal volunteers participated in the study. IFNá was determined by enzyme linked
immunosorbent assay (ELISA). Nitric oxide was
assayed by methemoglobin method.
Results: Plasma IFN-á level in normal volunteers
was 17.09±7.49 pmol/ml incontrast the IFN-á level
in AIHD patient was 1.6±0.053 pmol/ml
(p<0.0001). The plasma nitric oxide level in
normal was 0.4±0.02 nmol/h decreased to 0 pmol/
h in AIHD patients. After recuperation the impaired
IFN-á and NO levels in AIHD were found to return
to normal level.
Conclusion: Severe reduction of IFN-á synthesis
due to the decreased synthesis of NO resulted in
the impaired thromboprotection by the cytokine
in AIHD. And, as such the decreased plasma IFNá level might be a hither to unrecognized risk factor
for AIHD in men.

Department of Biochemistry, Kamineni Institute of Medical Sciences, Narketpally,508254.AP.
[email protected]
Introduction: Atherogenic Index defined as
log(TG/HDL-c in mmol/l) has recently been
proposed as a marker of atherogenicity.An
abnormal ratio of Triglycerides(TG) to HDL
indicates an atherogenic lipid proûle and a risk
for the development of Myocardial infarction.
Objective: To estimate and compare the
Atherogenic Index in patients diagnosed with MI
with that of controls.
Methods: 100 Patients attending cardiology
department with symptoms of Acute MI with high
Cardiac Troponin T(cTnT) were selected as
patient group, and healthy subjects were selected
as
control
group.
Serum
Total
Cholesterol(TC),HDL and TG were measured
using COBAS INTEGRA, and cTnT by using
COBAS E411 Electrochemiluminescence.
Results: Patients were divided into 3 groups
depending
upon
cTnT
levels.
172
Group1(controlgroup):cTnT<0.010ng/ml
Group2:cTnT
upto
0.1ng/ml
and
Group3:cTnT>0.1ng/ml. In Group1:The Mean and
SD of Atherogenic Index was 0.22±0.18,
TG:135.31±46.21mg/dl, TC:149.85±34.09mg/
dl,HDL: 33.69 ± 6.87 mg/dl. In Group 2:
Atherogenic Index was 0.36 ± 0.22, TG: 222 ±
119.73 mg/dl, TC: 204.69 ± 56.70 mg/dl., HDL:
35.69 ± 5.10mg/dl. In Group3: Atherogenic Index
was 0.32 ± 0.14, TG: 180.45 ± 56.69mg/dl, TC:
181.96 ± 48.35 mg/dl., HDL: 34.66 ± 5.67mg/dl.
Atherogenic Index was significantly increased in
patients with microinfarcts (p<0.0001) when
compared with normals.Patients with frank infarcts
had higher Atherogenic Index when compared to
patients with microinfarcts.( p>0.05 ).
Conclusion: Other than serum choleterol levels,
elevated triglcerides and lower HDL significantly
contribute to elevated atherogenecity and increase
the risk of MI.

Objective: Atherosclerosis is the common cause
for ischaemic heart disease (IHD) and the mortality
and morbidity related to it. There are various
indicators to predict the risk for development of
atherosclerosis. The aim of our present study was
to measure atherogenic index of plasma (AIP) and
TC/HC ratio in IHD patients and to check the
relationship between them.
Methods: Serum lipid profile, AIP and TC/HC
ratio was estimated in 32 IHD patients and 32
healthy controls. Lipid profile was analyzed by
auto analyzer and TC/HC was calculated. AIP was
calculated using formula log [TG/HDL-C].
Results: There was significant increase in TC, TG,
LDL-C, AIP, TC/HC (p<0.001) and significant
decrease in HDL (p<0.001) in cases compared to
controls. Significant positive correlation was
observed between AIP and TC/HC.
Conclusion: According to our study IHD patients
are more prone to the development of
atherosclerosis due to high TC/HC ratio and AIP
when compared to healthy controls. AIP can
predict the size of LDL particle and high LDL
levels and size are important factors in
development of atherosclerosis. Along with TC/
HC, AIP can also be used in routine laboratory to
predict the risk for development of atherosclerosis
in IHD patients.

Appearance of Dermcidin, a Heat Shock Protein, as a Risk Factor for Acute Ischemic
Heart Disease through the Inhibition of Pancreatic Insulin Synthesis
Rajeshwary Ghosh and Asru K. Sinha*
*Sinha Institute of Medical Science and Technology, 288 Kendua Main Road, Baishnabhghata, Garia,
Objective: The occurrence of hyperglycemia is
commonly associated with acute myocardial
infarction and unstable angina. The association
of hyperglycemia is reported to result in the worst
prognosis of the functional recovery in this
condition. The mechanism in hyperglycemia in
AIHD remains obscure. We investigated the role
of an inhibitor in the circulation in AIHD for the
inhibition of glucose induced pancreatic insulin
synthesis.
Methods: The synthesis of insulin was determined
by in vitro translation of the isolated mRNA from
the islets of Langerhans from the mice pancreas
exposed to glucose and determined by enzyme
linked immunosorbent assay (ELISA).
Results: The treatment of the islets of Langerhans
with the plasma from AIHD patients but not with
the plasma from normal volunteers in the presence
of glucose resulted in the inhibition of insulin
synthesis from 0.148µunits of insulin /mg of islets/
h in the control experiment to 0.012 µunits of
insulin /mg of islets/h in the presence of AIHD
plasma. This inhibitor from the AIHD plasma was
isolated by preparative SDS gel electrophoresis.
The isolated protein band (14kD, a single
polypeptide chain) that was found to inhibit
glucose induced insulin synthesis was determined
to be Dermcidin isoform 2, an oxidative stress
protein by the amino acid sequence analysis.
Conclusion: The appearance of Dermcidin in the
circulation in AIHD, would superimpose a
prothrombotic condition over the existing AIHD
through the impairment of insulin which is
established to be a potent antithrombotic hormone
in recent time.

Objective:LDL is heterogeneous in terms of size,
density, electric charge and chemical composition
with some particles of LDL (small dense LDL
particle) showing greater atherogenecity
compared to other particles. Studies on LDL
heterogeneity are not available in resident Indians.
Since data is not available in Indians it would be
pertinent to look at LDL heterogeneity in a resident
Indian population and look at their association
with other known biochemical risk factors of CAD
like lipids, Apo A, Apo B, Lipoprotein (a) and
hsCRP.
Methods:183 employees of an industry in Delhi
with age range 30 -39 years were screened for their
LDL particle size in plasma by 3% polyacrylamide
gel electrophoresis. Their lipids, Apo A, Apo B,
Lipoprotein (A) and CRP were estimated. The
study included 140 males and 43 females.
Results: 41 males (29.3%) and 11 females
(25.6%) had LDL particle size less than 26.3 nm.
The group with LDL particle size d” 26.3 nm
(pattern B) (n=52) were compared with the group
having LDL particle size > 26.3 nm (pattern A)
(n=131). Females with particle size d” 26.3 had
significantly higher total cholesterol, LDL-c,
lipoprotein (a) and hsCRP than females with
particle size > 26.3 nm. Among males, Apo B was
significantly higher in the d” 26.3 group. Apo B,
lipoprotein (a) and
hsCRP was significantly
higher in the < 26.3 group when males and females
were combined.
Conclusion:A high prevalence of small dense LDL
(particle size < 26.3 nm) was observed in the
industrial population studied. There was a
significant difference in lipid parameters in the
subjects with the A and B phenotype. This confirms
that the atherogenic LDL particle size (pattern B)
is associated with other cardiovascular risk factors
in Indians.

Objective: Essential hypertension, the form of
hypertension in men, is a major risk factor for
coronary artery disease (CAD). No etiological
reasons, no gene or any definable cause for
essential hypertension is currently known. And,
as such, there is no diagnostic test for the condition

the existence of an antihypertensive protein
hormone produced in the kidney cortex and named
the protein “cortexin”.

Ischemia Modified Albumin – an Evolving Diagnostic Marker of Myocardial
Ischemia
Dr Sudeshna Behera and Prof. P.C.Mohapatra
Department of Biochemistry , S.C.B. Medical College, Cuttack, Orissa, INDIA; Email id –
[email protected]
Background: Establishing a diagnosis of Acute
Coronary Syndrome (ACS) in clinical setting
remains a challenging task. Currently cardiac
markers like Myoglobin, Cardiac Troponin T
(CTnT) and CK-MB are commonly used in
assessing cellular necrosis in patients attending
emergency department with symptoms of acute
chest pain. However there is no accepted gold
standard for detecting myocardial ischemia. So it
is difficult for the clinicians to prevent the
progression of myocardial ischemia to irreparable
myocardial damage. Recently a new marker
Ischemia Modified Albumin ( IMA ) has been
introduced as a highly sensitive and early
detectable marker of myocardial ischemia.
Objective: The present study was conducted to
evaluate serum IMA concentration in acute
coronary syndrome patients and to assess its
diagnostic importance in cases of suspected
myocardial injury.
Methods: The study evaluated IMA in conjuction
with ECG and CTnT in thirty five ACS patients
178
presenting to the emergency department within 3
hrs of acute chest pain. thirty healthy volunteers
served as control. The levels of IMA were
determined by Albumin Cobalt Binding (ACB) test
and readings were taken at 470 nm by
spectrophotometer. Serum MDA and Vitamin E
levels were also assessed in all patients.
Results: Serum IMA levels were observed to be
significantly raised (P<0.05) in acute coronary
syndrome patients than controls. Rise in IMA
demonstrated an association with MDA and
Vitamin E revealing its genesis due to oxidant
stress. The high sensitivity of IMA alone as well
as in combination with ECG and CTnT makes it a
better and an early diagnostic marker of
myocardial ischemia.
Conclusion: IMA can be measured accurately ,
reliably and within an acceptable time period to
be useful in the evaluation of patients with ACS.
It could bring a new dimension to the care and
management of patients at an early stage.

Email id:[email protected]
Background: Diabetic retinopathy is a sight
threatening complication of diabetes mellitus and
is one of the leading causes of acquired blindness.
There is a series of risk factors related to the
development and progression of diabetic
retinopathy such as hypomagnesemia,
dyslipidemia, duration of diabetes, poor diabetes
control.
Objective: 1. To estimate serum magnesium,
HbA 1c , total cholesterol, triglyceride and
microalbuminuria in type II diabetic patients with
and without retinopathy. 2. To compare and see if
there is any significant correlation between these
parameters in diabetic patients with retinopathy.
3. To compare the levels of these parameters with
the healthy volunteers.
Methods: The study included 30 diabetic patients
with retinopathy, 30 diabetic patients without
retinopathy and 30 healthy controls. Serum
magnesium, HbA1c, total cholesterol, triglyceride
and microalbumin in urine were estimated.
Results: There was a significant increase in the
FBS, HbA1c and microalbumin in urine in diabetic
patients with retinopathy and also in diabetic
patients without retinopathy, when compared to the
control group. There was a significant decrease in
the serum magnesium levels in the diabetic groups
when compared to the controls. However there was
no significant variation in the total cholesterol
levels in the study groups. The severity of diabetic
retinopathy in the studied groups was influenced
by factors such as duration of diabetes mellitus,
good glycemic control, hypomagnesemia and

The Effects of Kidney Function and Transplantation on Biochemical Correlates of
Cardiovascular Health
Thompson. M.J.W. 1 and Ray1.U.

, University of Tasmania, Hobart, Australia1; Royal Hobart Hospital Hobart, Tasmania, Australia2.
Background: It is consistently now being
appreciated that chronic renal dysfunction alone
is an independent risk factor for the development
of coronary artery disease, and for more severe
coronary heart disease (CHD)[1,2,3,4]. One in
seven Australians show signs of chronic kidney
disease (CKD). CKD is a potent, independent risk
factor for cardiovascular disease (CVD). Risk of
CVD is directly proportional to degree of kidney
impairment. As well as independently increasing
the risk of CVD, kidney dysfunction also adversely
impacts upon other biochemical determinants of
cardiac health. Kidney impairment increases total
cholesterol (TC), triglycerides (TG), low density
lipoprotein (LDL), urates & decreases high density
lipoprotein (HDL). It has also been suggested that
kidney impairment induces a state of insulin
resistance in the absence of pre-existing diabetes
179
mellitus or other comorbidities know to cause
insulin resistance. Insulin resistance results in
resulting in impaired glucose metabolism and
hyperglycaemia, further worsening CVD risk
profile. These biochemical derangements are seen
in even the earliest stages on kidney impairment.
Thus kidney function has an important role in
maintaining cardiac health. Optimal treatment for
end-stage kidney failure (ESKF) is kidney
transplantation. Previous studies have shown a
decrease in CVD risk in patients who underwent
kidney transplantation compared those patients
who did not. However, CVD risk in patients who
receive a transplanted kidney remains elevated
above the general population. We propose that
improved plasma lipid profile and reduced
inflammation may contribute to this decrease in
CVD risk.
Objective: To examine the relationship between
kidney function, lipid profile and urate and see
how these are affected by kidney transplantation
in non-diabetic patients with ESKF.
Methods: We conducted a retrospective analysis
of non-diabetic patients (M= 15, F= 7, Age = 1972) who had received a kidney transplant within
the last ten years at the Royal Hobart Hospital.
Patients with diabetes were excluded on the basis
of request notes and clinical history. Only patients
who had baseline measurements prior to
transplantation and post transplantation
measurements were included in the study.
Results: HDL decreased with increasing degree
of kidney dysfunction (p<0.0001) with even mild
degree kidney impairment impacting negatively
on HDL (p= 0.006). LDL, TC, TG & urate
increased with increasing degree of kidney
dysfunction (p<0.0001), despite statins use in
>90% of patients. These were seen to increase
even in mild stage kidney failure (p<0.0001).
Kidney transplantation resulted in a statistically
significant increase in HDL (Student’s t-test,
180
p<0.001) and also decreased TG levels (Student’s
t-test, p= 0.014) when compared to pretransplantation levels. LDL, TC & urate were also
decreased following kidney transplantation,
however the effect was not significant. Data were
also analysed using Piecewise 3-step regression
to examine temporal trends in HDL, LDL, TG, TC
and urates in pre- and post-transplant subjects.
Conclusion: Kidney impairment results in
changes to lipid profile and inflammatory status
that negatively impact on cardiovascular disease
risk. Changes in lipid profile and inflammatory
status are observed even in the earliest stages of
kidney failure. Kidney transplantation has a
positive effect on inflammatory status & lipid

Background: Preeclampsia one of the most
common complications of pregnancy is a major
cause of maternal, fetal and neonatal morbidity
and mortality. Many features of insulin resistance
syndrome have been associated with this
condition. Objective: The aim of this project was
to study the levels of insulin and lipoproteins in
pregnancy induced hypertension (PIH).
Methods: The study included 30 patients with
PIH, 20 patients with normotensive pregnancy and
20 age matched controls.
Results: The mean level of insulin was
significantly elevated in cases of PIH than the
controls (P< 0.001). The levels of total cholesterol,
TGL and LDL were significantly high and HDL
was significantly low among patients with PIH
than the controls.
Conclusion: The result of this study indicates that
insulin resistance plays a role in pathogenesis of
PIH. Such patients are at an increased risk for
future cardiovascular disease. Interventions to
reduce insulin resistance will minimize later life
cardiovascular complications.

Background:Cardiovascular diseases are the
leaders in modern day lifestyle disorders. The risk
factors are multiple and their relationships are
complex. Emerging risk factors should be
compared with established risk factors before its
clinical usefulness can be ascertained.
Objective: This study was done to evaluate the
novel risk factors of coronary artery disease
(CAD) with respect to the degree of coronary
occlusion.
Methods:The study was comprised of 33 patients
who under went coronary arteriography (CAG).
9 had normal coronary, 9 had single vessel block,
while 15 patients had double vessels blocks.
Classic serum lipid profile included total
cholesterol (TC), triglyceride, high density
lipoprotein (HDL), low density lipoprotein (LDL).
Novel serum lipid profile included apolipoprotein
A1, apolipoprotein B and lipoprotein (a) by
immuno-turbidometric assays.
Results: Mean TC, LDL levels and both the
atherogenic indices TC/HDL and LDL/HDL
showed ascending trend when compared between
the groups. Mean Apo A-I in normal vessel group
was highest (155 ± 11.78 mg/dl) while in double
vessel block group it was lowest (135.60 ± 28.50
mg/dl). However, mean lipoprotein (a) level
showed divergent trends from normal coronary
vessel (5.44 ± 3.30 mg/dl), single vessel block
group (13.02 ± 13.30 mg/dl) highest in double
vessel block group (52.87 ± 28.42 mg/dl).
Conclusion:Lipoprotein (a) is a better marker than
LDL which correlated with the degree of occlusion.
Higher Apo A-1 and A1/B ratio are the potential
biochemical markers of anti-atherogenicity while
elevated Lipoprotein (a) appears to be a dangerous
atherogenic force that lead to CAD.

A.K.Srivastava
Department of Laboratory Medicine, All India Institute of Medical Sciences, New Delhi, India;
Email : [email protected]
Optimizing all the steps in the testing cycle is as
crucial to the success of point-of-care testing
(POCT) as the measurement process itself. The
complete POCT process or testing cycle is a complex series of events that involve many parties in
any clinical organization. Consultation with all the
people concerned is important and has led to the
formation of institution-wide Point-of-Care Coordinating committee. In recent years, the focus
on developments in point-of-care (POCT) from a
preoccupation with the analytical process to a
broader perspective that takes into consideration
other procedures which take place before and af-
ter the measurement process. This has come after
realization that success with POCT requires optimization of the many different steps that make up
the total testing process or cycle. Outside forces
have also played in this change of focus, particularly those concern with promoting total quality
management and patient safety. As well as ensuring that POCT meets required standards on a dayto-day basis, the role of clinical scientists on the
committee is to ensure that the POCT process continues to meet clinical needs through audit and, if
necessary, changing testing procedures.

Background: Osteoporosis is a major metabolic fracture in 40% of aging women and 15% of aging
bone disease which over a lifetime results in hip men. The recognition of osteoporosis as a disease
186
that leads to fracture risk, offers new insights into
its epidemiology. Homocysteine is an amino acid
intermediate formed during the metabolism of
methionine and studies have shown it to be a
strong independent risk factor for hip fracture in
older men and women. The knowledge about risk
factors for hip fracture in Asian population is very
much limited and the mechanism(s) by which
increased levels of homocysteine are associated
with osteoporosis is poorly understood.
Objective: To analyze the homocysteine and other
biochemical parameters such as calcium,
phosphorous, & alkaline phosphatase which will
be compared to the Bone Mineral Density (BMD).
Methods:The present investigation involves new
cases with recent history of hip fractures (n = 50)
and the healthy age and sex matched controls (n=
50). The analysis of the biochemical markers is
done in fasting blood samples by using fully
automated analyzer. Student ‘t’ test is used to
analyze the data. This study will evaluate the role
of these markers in osteoporotic hip fractures.
Conclusion:The present investigation will try to
throw light on the understanding of the
pathophysiology of the Osteoporotic hip fracture
which will help planning preventive strategies with
regard to the incidence of osteoporotic hip fracture
in future.

[email protected]
Introduction: Attention Deficit Hyperactivity
Disorder (ADHD) is one of the most frequently
diagnosed childhood psychiatric disorders. Based
on various empirical estimates, symptoms of
ADHD persist into adulthood in about 30-50% of
the childhood cases. Studies have shown RBC and
plasma cholinesterase show unique patterns of
differences in patients with various
neuropsychiatric disorders including ADHD as
compared to controls indicating involvement of
cholinergic system in these disorders. Antagonism
of neuronal nicotinic acetylcholine receptors have
shown to ameliorate the core symptoms of various
neurological disorders associated with
hyperkinesis, attention and memory loss. Patients
lacking circulating serum ceruloplasmin presented
with neurodegeneration. Animal experiments that
showed lack of ceruloplasmin was associated with
redox injury in the brain. Also copper deficiency
has been implicated in neurological impairment
seen in Wilson disease.
Methods: After obtaining clearance from
institutional ethics committee, we estimated
salivary ceruoplasmin (Ravin.H.A et al) &
cholinesterase (Ellman’s method) from 12 controls
& 9 subjects in the age group 5 – 12 yrs and their
values were compared
Results: Pseudocholinesterase showed significant
increase (p< 0.001) in subjects as compared to
controls.Ceruloplasmin levels showed marginal
decrease(p=0.065) in subjects as compared to
controls however it was not statistically significant.
Conclusion: Results show the role for cholinergic
system and ceruloplasmin in ADHD. Also saliva
can be an effective alternative tool for evaluation.

Objective:The intake of fat, an essential
macronutrient of diet vary widely among
188
individuals and changes over time. Traditional
dietary assessment methods are prone to errors and
bias; hence an objective measurement is important
to assess intake. Technical advancements have
made it possible to study fatty acid even from
small tissue samples; hence we have explored the
suitability of using cheek cell epithelium as a
non invasive tissue for assessing dietary fatty acid
intake.
Methods: Blood and cheek cells were collected
from 17 subjects in fasting state at the same time.
Dietary data was collected through 24 hrs recall
and food frequency questionnaire. Lipids were
extracted from cheek cell and serum; fatty acids
converted to methyl esters and were run on GC.
Fatty acids were identified by comparing their
retention time with known standards. Dietary fatty
acid was computed from the food composition
tables.

(8.75) and 24.76 (3.74) respectively and PUFA was
12.76 (6.04) & 24.52 (3.34) respectively. Palmitic,
stearic and oleic acid were the major fatty acids
identified in cheek cell and serum. There was a
significant correlation between MUFA (r = 0.35)
and arachidonic acid (r = 0.46) values obtained
between serum and cheek. The saturated fatty acids
in cheek cell correlated significantly with dietary
saturated fatty acid (r = 0.52). A correlation of 0.48
& 0.51 was observed for linoleic and total PUFA
in serum and diet respectively. The distribution of
fatty acid varied between serum and cheek cell.
Serum was richer in PUFA which reflected the
dietary intake of the subject, while cheek cell
reflected the saturated fatty acid intake which are
stored as fat.
Conclusion:In conclusion saturated fatty acids in

Objective: Altered hemostatic parameters both
coagulation and platelets in neonates is a call for
immediate attention, being a critical issue.
Understanding the normal reference range in this
group is essential prior to labeling a disorder.
Methods: 150 samples over a period of 2 years
studies for peripheral smear, platelets, prothrombin
time(PT), activated partial thromboplastin
time(APTT), fibrinogen and thrombin time(TT)
were assayed on Sysmex analyzer, CA 50 and
Stago ST 4. Factor XIII was done by urea clot
lysis time.
Results: Abnormal PT and APTT were seen in
38%, low fibrinogen levels in 10.8%. Factor XIII
abnormality was mainly due to low fibrinogen
levels preventing a clot formation. Hemorrhagic
disease of the new born was 34%. All studies were
done on follow up to confirm this. Factor VIII and
factor IX deficiencies were retested over a period
of 6 months to one year for confirmation unless
the history and clinical presentations identified a
congenital deficiency.
Conclusion: Close monitoring of neonates for
coagulation studies is related to the process of
phlebotomy and the specific reference range very
different from the adult. Deviation from this
protocol would mislead in over diagnosing simple

Immunological Studies on Glycated and Glycoxidated LDL: Implications in the
Pathogenesis of Various Diseases
Salman K A1, Alam R1, Arif N2 and Khan S1
Department1 of Biochemistry, JN Medical College, Aligarh Muslim University and Department2 of
Chemistry, Z H College, New Delhi.
Background: The entry of glucose into the brain
and peripheral nerve tissue, kidney, intestine, lens
and RBC does not depend on insulin action.
During hyperglycemia, intracellular level of
glucose in these cells is high. This promotes nonenzymatic attachment of glucose to protein
molecules (Protein Glycation). Glycation of
proteins leads to the formation of AGE’s
(Advanced Glycation End product) of diverse
molecular structure and biological functions. AGE
cross-links body proteins such as tissue collagen
or a nerve protein-myelin, lens crystalline. AGE
formation stiffens the extracellular matrix and
decreases the elasticity of, for instance the arterial
wall. Their formation also affects the function of
endothelial cells, phagocytes (macrophages) and
smooth muscle cells in the wall of blood vessels.
Through these mechanism AGE may contribute
to the development of the late complication of
diabetes other vascular diseases, aging and
rheumatoid arthritis.
192
Objective: The basic objective of this study is to
evaluate the level of glycated and glycoxidated
LDL in the sera of patients with vascular diseases
and diabetes.
Methods: Commercially available LDL was
modified by glucose and peroxynitrite generated
by SIN-1. The degree of LDL modification was
assessed by various physical and biochemical
parameters.
Results: Serum autoantibodies against native,
glycated and glycoxidated LDL was evaluated
in patients of cardiovascular diseases and diabetes.
The results showed the presence of high levels of
autoantibodies against glycoxidated LDL as
compared to native and glycated LDL.
Conclusion: Such research also will increase the
understanding of how AGES cause pathology and
the extent of AGE involvement in the various
complications of diabetes and vascular diseases.

Critical value reporting originally was highlighted
by Dr. Lundberg, who defined a critical value as
a result suggesting that the patient is in imminent
danger unless appropriate therapy is initiated
promptly. Reporting of laboratory critical values
has become an important issue for patient safety
as described in the National Patient Safety Goals
of the Joint Commission on Accreditation of
Healthcare Organizations (JCAHO).The recent
focus on patient safety has brought increased attention to the issue of laboratory critical value
reporting. Critical value reporting parameters may
be considered an important laboratory outcome
measurement because they reflect clinical effectiveness, patient safety, and operational efficiency.
For the critical value reporting process to be effective, the organization must understand and address the variables involved in the process. Herein,
we report the results of an analysis of 4260 consecutive laboratory critical values from July 2007
to December 2008 at our institution, a Joint Commission International accredited Tertiary care hospital to understand the scope of critical value reporting and identify opportunities for process improvement. We evaluated critical value reporting
by parameter, laboratory specialty, clinical care
area, time of day, and Turn around Time. Factors
leading to delays in critical value reporting are
identified, and we describe approaches to improving this important operational and patient safety
issue. We are proud to be the pioneer in Bangladesh
to introduce the system of Critical Call Back in
Lab medicine of Apollo Hospitals Dhaka which
was highly appreciated by the survey team of Joint
Commission on Accreditation of Healthcare Organizations (JCAHO) during our accreditation process

Rare cases of Pagets Disease of the Bone in India: Biochemical and Clinical
Evaluation and Follow-up in 2 Extreme Presentations
Dr CS Muralidhara Krishna ,Dr H L Vishwanath ,Dr S Sanjay, Dr Tejeswini Deepak, Dr A
Sharda and Dr SS Srikanta
Endocrinology and Diabetes Study Group, Samatvam and Jnana Sanjeevni Medical Center, and Dept
Biochemistry, Bangalore Medical College, Bangalore, India
Paget disease is a localized disorder of bone
remodeling that typically begins with excessive
bone resorption followed by an increase in bone
formation. Approximately 70-90% of persons
with Paget disease are asymptomatic and detected
based on the incidental finding of an elevated
serum alkaline phosphatase (SAP) level or
characteristic radiographic abnormality However,
a minority of affected individuals experience
various symptoms, including bone pain (the most
common symptom), secondary osteoarthritis, bony
deformity, and neurologic complications.
193
Although the etiology of Paget disease is
unknown, both genetic and environmental
contributors have been suggested. Ethnic and
geographic clustering of Paget disease is well
described. An environmental trigger for Paget
disease has long been considered but never proven
- viruses. Paget disease is estimated to occur in
1-3% of individuals older than 45-55 years and in
up to 10% in persons older than 80 years – Europe.
Paget disease is very rare in Asian countries,
especially India.
Bisphosphonates (eg
alendronate 40 mg/d PO for 6 mo) are first line
therapy - analogs of pyrophosphate, act by binding
to hydroxyapatite in bone matrix, thereby
inhibiting the dissolution of crystals.
Case 1: DS, 53 year male, was found (year 2008)
to have unexplained asymptomatic elevation of
SAP 625, 908, U/L (53-128), during a routine
annual diabetes health review; Pagets disease –
polyostotic was confirmed by isotope bone scan
(skull, vertebra, pelvis, femur, tibia, scapula,
sternum) and radiology; he was treated with the
initial cycle of alendronate ; during and after
therapy serial SAP levels decreased to 786, 521,
299 and 136U/L.
Case 2: BN,63 year female presented (year 2002
) to an orthopedic surgeon with severe L iliac bone
pain, leading to x ray studies - lytic bone lesions,
isotope bone scan, bone biopsy and a histological
diagnosis of “malignancy” – metastases from an
unknown primary - erroneous. Review by
endocrinologist established the diagnosis of Pagets
diseases – polyostotic (skull, vertebra, pelvis,
femur), SAP level of 1343,954,835. She received
two 6 months cycles of alendronate therapy in
years 2003 and 2007 (Serial SAP; Year
2003=130,168;Year
2004=232;Year
2005=322,Year 2006=339 ,Year 2007=575,Year

Department of Biochemistry, SRM Arts and Science College, Kattankulathur – 603 203, Tamilnadu
Objective: Assessing the patients’ response to
stress in terms of acute phase proteins maybe of
great value in determining the prognosis head
injury patients and also for providing possible new
therapeutic management protocol.
Methods: The present study was based on 103
prospectively selected patients admitted to the
male head injury intensive care unit, institute of
neurology, government general hospital Chennai.
Blood samples were drawn between 10 am and
11 am by venipuncture on admission (within first
24 hours of trauma) and on every alternate day
during the first week and once in a week during
the second and third week. The control group had
194
52 healthy volunteers .clinical outcome was
assessed based on the Glasgow outcome scale
(GOS) and the patients were classified into three
groups as group1: patients with good recovery,
group2: patients with moderate or severe disability
and group3: patients in persistent vegetative state
or death. Radial immunodiffusion (RID) assay was
used for c-reactive protein (CRP), ceruloplasmin
(CS) and transferrin estimation. Albumin was
assayed using dye binding method.
Results: The patients with head injury had a
profound acute phase response which lasted
throughout the 21 day study period. Increasing
level of CRP was noted up to fifth day, after which
it decreased slowly but still remained significantly
higher than control throughout the study period.
A similar trend was observed with CP levels in
which peak levels were recorded during the second
week. The concentration of transferin fell rapidly
after head injury and the levels remained below
normal in all the three groups throughout the three
weeks time. Using a stepwise regression analysis
a prognostic index was derived. GCS predicted
the outcome of 61.1 % of patients correctly
whereas in conjunction with T4, TCS, TRP and
CP the prognostic ability improved to 86.5 %.
Stepwise multiple discriminant analysis yielded
three prognostic indeces I, II and III for group 1, 2
and 3 respectively with a correct prediction average
of 93.2.
Conclusion: From the discriminant function
analysis it was found that acute phase reactant such
as CP and CRP may be of paramount help to
distinguish group 2 patients from others

Biochemical Profile of Cord Blood in Normal Pregnancy and Pregnancy
Induced Hypertension.
Dept. of Biochemistry ,ASRAM Medical college , Eluru, A.P; Email : [email protected]
Background : Pregnancy induced hypertension
(PIH) is a significany health problem and is the
leading cause of maternal and perinatal mortality
and morbidity. Low birth weight and prematurity
is common in such cases.
Objective: This study was designed to compare
certain biochemical parameters in cord blood of
children born to mothers with PIH and to mothers
with normal pregnancy.
Methods: For this purpose 10ml of cord blood
during delivery was collected from mothers
attendingobstetrics department at ASRAM
medical college,Eluru.30 samples were collected
from mothers with uncomplicated pregnancy and
50 samples from the mothers with PIH (maternal
age matched).The 50 samples include group A20 mothers with pre-eclampsia and group B-30
mothers with gestational hypertension.The
biochemical parameters measured were
glucose,urea,total
proteins,total
cholesterol,calcium & magnesium.
Results: It was observed that all the parameters
except for total cholesterol and calcium were
significantly lower(p<0.00001) in the cord blood
of babies born to mothers with PIH.The total
cholesterol and calcium were significantly higher
in the same cases (p<0.001).On comparison of
parameters of cord blood in babiesweighing >
2.5kg in cases vs controls,there was significant
decrease in all the parameters in the former.
Conclusion: So the neonates born to mothers with
PIH must be screened carefully to prevent mortality
and morbidity due to low levels of the important
biochemical parameters like glucose and
magnesium.Neonates weighing >2.5kg are also at
similar risk

Background: Both menstruation and pregnancy
are inflammatory conditions that cause a degree
of physiological ischemia-reperfusion.
Contractility of uterine smooth muscle is essential
for the cyclic shedding of the endometrial lining
and also for expulsion of the fetus during
parturition. Cyclic nucleotide phosphodiesterases
(PDEs) are a diverse enzyme group with multiple
regulatory properties and wide tissue distribution.
Such activity includes cyclic adenosine (cAMP)
and guanosine monophosphate (cGMP)
breakdown. Cyclic nucleotide accumulation has
been implicated in dilatation of intact tonic spiral
arteries uterus and in relaxation of myometrium.
Isoforms of the PDE4 family are shown to be
involved in smooth muscle contraction and
inflammation. PDE4 inhibitors have been shown
to prevent inflammation-induced preterm delivery.
age 21 yrs in the premenstrual period and on first
day of menstruation. Their respective premenstrual
and menstrual levels were compared.
Results: We observed that there is a significant
increase (p <0.05) in the phosphodiesterase levels
in the menstrual period as compared to their
respective values in the premenstrual period.
Conclusion: Our results show that there is a
significant change in levels of plasma
phosphodiesterase indicating their possible role in
uterine contraction.

Study of Effect of Phototherapy on Neonatal Hyperbilirubinemia
M Vijay and M Malathi.
Department of Biochemistry, Father Muller Medical College Mangalore, Karnataka.
Email:[email protected]
Objectives 1. To study effect of phototherapy on
neonatal hyperbilirubi-naemia. 2. To compare
effect of photo-therapy on term and preterm
neonates.
Methods: The present study was conducted at
between January 2009 and may2009 in Father
Muller Medical College, Mangaore. Patient’s data
were collected from NICU phototherapy Unit of
department of paediatrics. 42 cases were identified
out of which 25 were term and 17 were preterm
babies. Phototherapy was initiated by
paediatrician according to clinical assessment, lab
results and reference charts. Mode of phototherapy
is continuous. Blood level of bilirubin; (total,
unconjugated and conjugated in mg/dl) were
analyzed by auto analyzer Olympus-AU 400.
Levels of bilirubin recorded daily in the laboratory
of department of Biochemistry. Effect of
phototherapy on neonatal unconjugated
hyperbilirubinaemia was studied. Data were
analysed by paired “t” test. The values of
significance were evaluated with ‘p ’values. The
difference were considered significant at p<0.05.
Results: Phototherapy is effective treatment for
neonatal jaundice and the mechanism-is well
defined. The therapeutic effect depends on the light
energy emitted in the effective range of
wavelengths, the distance between the lights and
the infant, and the amount of skin exposed, as well
as the rate of hemolysis and in vivo metabolism
and excretion of bilirubin. In our study
phototherapy was effective in term neonates, as
decreasing level of both total and unconjugated
bilirubin is significant when compared daily.
However phototherapy was effective in preterm
neonates, but decreasing level of both total and
unconjugated bilirubin is not significant because
preterm neonates take longer duration.
Conclusion: Jaundice is the most common clinical
symptom and sign in neonatal period, arising from
either overproduction or under secretion of
bilirubin. Almost all neonates (60% Term and 80%
Preterm) will have bilirubin greater than 5 mg/ dl
in the first week of life and about 6% of term babies
will have levels exceeding 15 mg/ dl. Due to
197
immaturity of the enzymes involved in bilirubin
conjugation. High levels of unconjugated bilirubin
are toxic to the newborn – due to its
hydrophobicity it can cross the blood-brain barrier
and cause a type of mental retardation known as
kernicterus. If bilirubin levels are judged to be too
high, then phototherapy with UV light is used to
convert it to a water soluble, non-toxic form.
Management of jaundice is directed towards
reducing the level of bilirubin and preventing CNS
toxicity. Bilirubin in the skin absorbs light energy,
which by photo-isomerization converts the toxic
native unconjugated 4Z, 15Z-bilirubin into the
unconjugated configurational isomer 4Z, 15Ebilirubin. The latter is the product of a reversible
reaction and is excreted in bile without any need
for conjugation.

Objectives: Pathology Laboratories typically
receive many repetitive telephone calls from
Doctors, Nurses and Phlebotomists enquiring
about what tube they need to use to collect a blood
sample for various tests. In our practice these
clients do have access to an online web database
but many claim that they do not have convenient
access to a PC to use that. This project involved
the development of a mobile phone SMS based
system which we anticipate will reduce the amount
of time ‘wasted’ on handling these calls.
Method: Our existing specimen requirements
database,
currently
viewable
at
www.centrepath.dhhs.tas.gov.au has been ported
to an SMS database query server for this project.
Typically our clients interact with this system as
follows
Specimen collection staff cannot recall what tube
to use when they are just about to collect a blood
sample for cholesterol testing so they create a
198
quick SMS query message on their mobile phone
eg ‘cholesterol’
They then send this SMS message to our SMS
database server
Our system uses a unique program to query the
database and respond
‘Cholesterol : 4ml blood, red top tube, patient
should be fasting for 12 hours. Results same day.’
If the SMS text from the caller is not immediately
recognisable eg Creat then the system responds
with a few options
‘Did you mean
Serum Creatinine
Urine Creatinine
Creatinine clearance
None of the above
Respond by SMSing us the closest number from
this list’
If the SMS text query is totally unrecognisable
then, in Release 2 of the software, it will alert our
Specimen Reception staff who will then phone
back the caller.
Results: The Release 1 of the software has been
shown to be capable of handling SMS query
messages via a GSM modem. It has been able to
analyse the content of the message to find key
acronyms and has used these to search the
database. Once the acronym has been matched
then the relevant information has been compiled
and formatted to the size of a standard SMS text
message (160 characters) and this has been sent
back to the mobile number from which the request
originated.
Basic session management has been implemented
as part of Release 1. The system has opened new
sessions for each new SMS query that it has
received. If a query has been matched exactly by
the database then the system has responded with
the name of the matching test and the relevant tube
information. The session has then been closed. If
there have been multiple matches for the query,
the system has responded with a simple “Did you
mean?” and provided a list of the possible
alternatives, with the final one being “None of the
above”. When the user has chosen one of the
options, then the corresponding database entry has
been sent. The session has been kept open until
the user replies with an option. If the user has
chosen the last option, “None of the above”, then
the query and the user details have been logged,
but Pathology has not been notified in this Release
1 version. This has closed the session. Any open
sessions have been terminated after 10 minutes if
the user has not responded. Unresolved queries
have been notified via an SMS from the system to
the user.
Conclusion: The basic functionality has been
shown to be achievable and by the time of
presentation delegates to ACBICON will be able
post SMS queries from their own mobile phones
into our system in real time. In addition the various
system management reports on usage statistics will
be demonstrable

Storage Stability of Glycosylated Hemoglobin in Red Blood Cells and Dried
Blood Spots
Ruby Gupta, Ramakrishnan Lakshmy, Dorairaj Prabhakaran and Kolli Srinath Reddy
Department of Cardiac Biochemistry, All India Institute of Medical Sciences, New Delhi-29.
[email protected]
Background: Glycosylated hemoglobin (GHb)
is an indicator of long term management of plasma
glucose; therefore it is essential that the
measurement of GHb be easier, especially for
distance monitoring in health care, population
screening and clinical trials. For the purpose of
distant monitoring and research, the stability of
samples collected and their appropriate storage is
of major concern.
Objective: Keeping these points in view, we have
estimated GHb in RBCs as well as dried blood
spotted on filter paper (DBS) and compared with
Whole Blood (WB).
199
Methods: To study the effect of storage,
accounting for the lapse of time during
transportation of samples from one place to
another, GHb was estimated in RBCs and DBS
after 30 days of storage. Twenty samples were
collected from the routine collection counter.
Blood spots were prepared on Whatman filter
paper and dried at room temperature. These DBS
were then stored in zip-lock poly bags. An aliquot
of whole blood was separated for analysis of GHb.
The rest of the blood was centrifuged at 2500 rpm.
Plasma was discarded and RBCs were stored for
the estimation of GHb. Analysis was done on day
1 and day 30.
Results: The mean GHb measured in WB, RBCs
and DBS were 6.50 ±1.44 %, 6.10 ±1.44 % & 6.70
+ 1.25 % respectively. The correlation coefficient
(r) between WB & RBCs was 0.996 & between
WB and DBS it was 0.986. The mean GHb in
RBCs were 7.07 ± 1.95 % on day 1 and 7.0 ± 1.75
% on day 30 (r = 0.983). The mean values for
DBS was 7.21 ± 1.55 % on day 1 and 7.36 ± 1.42
% on day 30 (r = 0.950).
Conclusion Glycosylated Hemoglobin in RBCs
and Dried Blood Spots showed good correlation
with the values in Whole Blood and were also
stable on storage up to 1 month and therefore can
be used in population screening and clinical trials.

Dept of Pathology, Theism Ultrasound Centre, 14-B, Dumdum Road and 3A/13 B K Paul Avenue,
Kolkata 700030; Email: [email protected]
Methods: The present work involves a systematic study of blood samples sent to a NABL accredited Clinical Biochemistry Laboratory to obtain normal and abnormal percentages of various
test values. The common tests performed on these
samples are for plasma glucose, serum urea, creatinine, uric acid, cholesterol, liver function tests,
lipid profile, electrolytes and hormonal analysis.
The daily average of samples analysed is 300 and
the tests performed is 600. The instruments used
are Cobas Integra 400, Elecsys 2010, Roche 9180
ISE and Cobas 6000. The present analysis considers an annual input of 1,59,894 tests.
Results: Plasma glucose was normal for 66%,
hypoglycemia occured in 0.9% and hyperglycemia was found in 33.1% cases. Urea was normal
in 92%, high in 7.8% and low in 0.2% cases. Uric
acid was normal in 87% cases while 13% had high
200
values. Bilirubin value was normal in 97%, high
jaundice was observed in 3% of which 5% cases
were HbsAg positive. Cholesterol in 90.7% cases
was normal and 9.3% cases were high. Triglyceride was normal in 78% with 22% cases being high.
Thyroid function tests were normal in 81.2%,
hyper in 3.6% and hypo in 15.2% cases. Electrolyte imbalances were observed in 17.2% cases of
which 60% were aged above 65yrs.
Conclusion The inference is that almost 10%
cases of urea, uric acid, bilirubin and cholesterol
are abnormal; tryglycerides, thyroid function and
electrolytes were abnormal in almost 20% cases
and hyperglycemia had the highest occurrence.
Increasing tendency of these trends may be due to
stresses, pollution in the city and also lifestyle
changes caused by globalization.

Dr. Revathi P. Shenoy
Department of Biochemistry, Kasturba Medical College, Manipal, India-576104.
Background: Attention-deficit hyper-activity
disorder (ADHD) is the most prevalent behavioral
disorder in children and the pathophysiology
remains obscure. Ionic magnesium (Mg(2+))
depletion has long been known to cause
hyperexcitability with convulsive seizures in
rodents, effects that have been reversed by
treatment with magnesium. A positive influence
of magnesium in the prevention and treatment of
hyperactivity in children is frequently raised in
literature. The magnesium levels were found to
be moderately decreased in plasma and
erythrocytes, and the Mg2+ -ATPase activity was
also reduced in ADHD children. Oxidative stress
may be a common pathogenic mechanism
underlying many major psychiatric disorders, as
the brain has comparatively greater vulnerability
to oxidative damage.The levels of protein thiols
in the body indicate antioxidant status.
protein thiol by Ellman’s method and Magnesium
by colorimetric method.
Results: Salivary thiols showed a significant
increase in subjects (p < 0.001) as compared to
controls and magnesium showed significant
decrease in subjects (p < 0.01) as compared to
controls.
Conclusion: This result substantiates the role of
oxidative stress and magnesium in
pathophysiology of neurological disorders. Also
saliva can be an effective alternative tool for
evaluation.

Laboratory in Delhi
A Manocha, S Bhargava, M Kankra, S Das and LM Srivastava
Department of Biochemistry, Sir Ganga Ram Hospital, New Delhi, India
Background: Competence of clinical laboratories
has been increasing in India due to quality
management and accreditation. This is assured by
producing accurate and precise data for patient
care. Establishment of quality indicators allows
detection and quantification of problems, which
are essential for complete quality checks. Internal
Quality Control (IQC) is based on daily monitoring
of test procedures performed in the laboratory.
External Quality Assurance Scheme (EQAS)
refers to objectively checking laboratory results
through an external agency and includes inter –
laboratory comparisons. EQAS plays a
complementary role to IQC. According to ISO
15189, the laboratory is encouraged to use a third
party control material similar or identical to the
patient sample matrix.

%CV calculated. Control charts are maintained to
demonstrate the stability of the analytical
measuring systems. Two EQAS programs are
followed- ACBI/CMC EQAS and Randox
International Quality Assessment Scheme
(RIQAS). In the monthly ACBI/CMC EQAS
program, the laboratory’s performance is compared
with other labs and assessed by a Variance Index
Score. The three fortnightly RIQAS programs clinical chemistry, immunoassay and cardiac are
interpreted by Target Score and Standard Deviation

Educare Institute of Dental Sciences, Malappuram, Pin 676 504 and George Abraham, Malabar
Institute of Medical Sciences, Calicut, Pin 673 016; e mail – [email protected]
Background: Protein electrophoresis is the
technique employed in major clinical laboratories
for screening abnormal proteins pattern in serum
and other biological fluids. Serum protein
electrophoresis is extensively employed for the
diagnosis and prognosis of many chronic diseases
such as myeloma, leukemia, nephrotic syndrome,
autoimmune diseases and acute phase reactions.
Objective: In the present study an attempt has
been made to evaluate the changes, if any, in the
serum protein electrophoretic pattern
Methods: Patients with chronic diseases who
were admitted in a tertiary care referral hospital
(Malabar institute of Medical Sciences, Calicut)
during the period from January to December 2006.
Patients with any chronic diseases showing
changes in their serum proteins pattern (as
assessed by the estimation of serum total proteins
by Biuret method and albumin by BCP dye
binding method) were included in the study.
204
During this period a total of eighty nine serum
samples were selected and subjected for serum
protein electrophoresis in Agarose gel (Ready to
use Hydragel Protein K (20) kit supplied by M/S
Sebia, France).
Results: Eight type of abnormal electrophoretic
patterns namely, hypergammaglobulinemia,
inflammatory disease, hypergamma globulinemia
with beta gamma bridge, monoclonal gammopathy
with M band, polyclonal gammopathy , free light
chain disease, hypogammaglobulinemia and
bisalbumi-nemia were observed. Hypergammaglobulinemia and inflammatory disease were
common constituting 48% and 27% of the total
cases respectively. The changes in the
electrophoretic pattern may be attributed to liver
diseases or autoimmune diseases. In
hypergammaglobulinemia and inflammatory
diseases the females were predominantly affected
(67% and 65% rrespectively). A seasonal variation
in the prevalence of inflammatory disease was
observed with maximum prevalence in summer.
Monoclonal gammopathy with M band and
hypergammaglobulinemia with beta gamma
bridge were seen in 4 patients each whereas
polyclonal gammopathy and freelight chain
disease were seen only in 3 cases each.
Bisalbuminemia and hypogamma-globulinemia
were very rare and could be detected only in one
case each.
Conclusion: From this study it can be concluded
that improved techniques of electrophoresis along
with software support is more useful in facilitating
the diagnosis of various diseases related to acute
phase reactions, chronic diseases and hyper/hypo
immune reactions in addition to multiple myeloma.

Ltd., CHENNAI.
Objective: Snakebites continue to be a major
concern in India. The polyvalent antivenom
available possess more problem in anaphylactic
shocks. The development of monoclonal
antibodies specific for various toxins of the venom
is the only solution. In the present study, an attempt
was made to characterize the various toxic
compounds of cobra venom and to raise specific
monoclones against the characterized toxic
compounds of cobra venom.
Method: Cobra venom was characterized by Ionexchange chromatography and the protein levels
in each fraction was estimated by Lowry’s
Method. The protein was purified by SDS and
NATIVE PAGE. The hemolytic activity of the
fractions was determined by direct microtitre plate
and indirect blood agar plate methods. The
Phospholipase A2 activity of the fractions was
determined by the direct tube and the indirct plate
methods. Cytotoxicity assay was performed to
determine the cytotoxic activity of the fractions.
Invivo immunization of balb/c mice was carried
out after determination of the lethal dose for cobra
venom. Hyperimmunized status of the mice was
confirmed by Double Immuno Diffusion method.
Cell fusion for hybridoma production was
performed and the monoclones were tested for
cross reactivity by ELISA technique.
Results: Cross reactivity for cobra venom was
checked using various monoclonal antibodies and
Krait venom antibodies were also found to be
reactive with the cobra venom antigen. Each
fraction should be used for the production of
monoclonal antibodies and further evaluation of
these antibodies could be used for therapeutic
purpose. This preliminary study could be used as
basis for studies on Naja naja toxin and its
neurotoxic nature. Also, this toxin can be used to
treat painful neurological movement disorders.

Development of a Novel Method to Eliminate the Negative Interference of Bilirubin
on Creatinine Assay by Jaffe’s Kinetic Method in Icteric Sera.
M.M.Goyal and A.Basak
Background: The negative interference of
bilirubin in creatinine assay by Jaffe’s kinetic
method is well documented. To remove this
interference various methods had been tried. So
far, very few methods provide solution to this
problem with limitations.
Objective: To develop a simple and economic
method to remove negative interference of
bilirubin on creatinine estimation.
Methods: Icteric sera were treated with reagent
‘X’ followed by precipitation of proteins. After
this, Creatinine was estimated by Jaffe’s kinetic
method in colourless supernatant.
Results: Our findings showed that reagent ‘X’
binds covalently bilirubin (both conjugated and
unconjugated) with serum proteins which were
precipitated out by precipitating reagent.
Creatinine was estimated and accurate values were
found out multiplying by a factor.
Conclusion: Our devised method effectively
removes bilirubin interference in creatinine
estimation. It is a simple procedure with good
repeatability and economic also.

Background: Common Clinical Biochemistry
investigations done round the clock often pose
great challenges to the Biochemists. Simple
example : in lipaemic serum no investigations can
be done. Sometimes, the procedure is
cumbersome, stability of reagents is a problem or
no method is available to estimate biomolecules
of clinical interest. Interferences of endogenous

triglyceride, uric acid estimation in icteric sera. A
very simple method of porphyria diagnosis,
detection of chyle in body fluids have been
developed. A very short procedure (1½ min.) of
plasma glucose estimation has been developed for
detection and prompt initiation of therapy of
hypoglycaemic patients as a life saving measure.
Plasma ketone bodies estimation is on the way. A
simple devise has been developed for collection
of two drops of blood by finger prick for glucose
estimation obviating venepuncture. These new
methods will be discuss.
Results: In our Clinical Biochemistry Laboratory,
we have developed few new methods to overcome
different day to day problems faced. Our team has

Background: A properly functioning quality
control program is one of the most effective
safeguards available to ensure good quality of
laboratory work, particularly in clinical chemistry.
No longer is it sufficient to feel that laboratory
results are satisfactory. It is rapidly becoming
necessary to know that they are satisfactory and
to have tangible evidence of competence. Quality
control measures provide that knowledge and
evidence.
Objective: The main objective of quality control
210
is to ensure good overall performance and thus
greatly to enhance the confidence that can be
accorded to any single estimation. Quality control
programs stress accuracy at the bench level.
Conclusion: This approach in itself is
praiseworthy, for if the estimation is in error, the
whole report is in error. Since each laboratory has
its own problems, variations in quality control
programs can be expected. Components of a
minimal program of quality control in clinical

Background: Osteosarcoma is a rare malignant
bone tumor most commonly occurring in children
and young adults presenting with painful swelling.
Status of fluoride levels in serum of osteosarcoma
is still not clear. Recent reports have indicated that
there is a link between fluoride exposure and
osteosarcoma.
Glycoproteins
and
glycosaminoglycans are integral part of bone and
prolonged exposure to fluoride for long duration
has been shown to cause degradation of collagen
and ground substance in bones
Methods: The present study was planned to
analyse serum fluoride, sialic acid, calcium,
phosphorus, and alkaline phosphatase levels in
twenty five patients of osteosarcoma and age- and
sex-matched subjects with bone forming tumours
other than osteosarcoma and musculo-skeletal
pain (controls, 25 each).
Results:Mean serum fluoride concen-tration was
found to be significantly higher in patients with
osteosarcoma as compared to the other two groups.
The mean value of fluoride in patients with other
bone forming tumours were though approximately
50% of the group of osteosarcoma, however was
significantly higher when compared with patients
of group I. Serum sialic acid concentration was
found to be significantly raised in patients with
osteosarcoma as well as in the group with other
bone forming tumours as compared to the group
of controls.
Conclusion: There was however, no significant
difference in the group of patients of osteosarcoma
when compared with group of patients with other
bone forming tumours. These results showing
higher level of fluoride, sialic acid and calcium in
patients with osteosarcoma compared to others

suffering from diabetes. A directly proportional
relationship was found between serum ferritin and
blood sugar levels. The correlation was found to
be significant.(P=0.006). Diabetics with increased
serum ferritin levels have significantly poor
glycemic control which was reflected by higher
levels of GHb. Similarly, significant relationship
is evident between increased serum ferritn levels
and neuropathy, nephropathy, retinopathy and
hypertension ,whereas no significant relationship
was found between increased serum ferritn levels
and Ischaemic Heart disease(P=NS).
Methods: The study was done on 50 obese type2 diabetic patients. They were compared with an
equal number of age, sex, BMI matched controls,
selected randomly to find out the correlation
between serum ferritn and blood sugar levels. The
patients were tested for the following parameters:

biochemical parameters.
Method: Five blood samples were collected by
venepuncture from 20 healthy individuals. One
before applying standard pressure and four after
applying standardized pressure of 60 mm of Hg(1
and 3 minutes) and 90 mm of Hg (1 and 3 minutes)
with help of sphygmomanometer. Glucose, Total
protein, Albumin, Urea, Creatinine were estimated
by kit method and analysed on semiautoanalyzer
manufactured by Transasia in collaboration with
Erba diagnostics (Germany).
Results: With increase in pressure and time there
was increase in the levels of total protein and
albumin and decrease in levels of glucose and urea
(p <0.05). However creatinine did not show change
in values on short term stasis, but prolonged stasis
(90 mm of Hg for 3 minutes) showed decrease in
values (p < 0.02).
Conclusion: From our results, we conclude that
the parameters in question are influenced by the
duration and magnitude of pressure applied, hence
tourniquet should be used meticulously.
Phlebotomists should be educated regarding the
usage of tourniquet so that we can identify and
prevent laboratory errors.

Background: Diabetes mellitus is chronic
metabolic disorder, with an absolute or relative
insulin deficiency, fasting hyperglycemia,
glycosuria leading to development of
atherosclerosis, microangiopathy, nephropathy
and neuropathy. It is increasingly believed that
strict glycemic control in diabetes prevents the
progress of late vascular or neurological
complications, therefore proper assessment of
glycaemic control becomes an essential part of
monitoring.

Department of Biochemistry, Kasturba Medical College, Manipal, Karnataka-576104; E-mail for
correspondence: [email protected]
Objective: Agarose gel electrophoresis of serum
proteins is a simple technique which provides
wealth of information in diagnosis of many
clinical conditions. Barbitone buffer has
traditionally been used in this technique and has
been shown to give proper separation of
components. But difficulty in access to
barbiturates has necessitated the need of an
alternative buffer. Some previous works have
used tris-borate in SDS PAGE, moving boundary
and immunoelectrophoresis of serum proteins.
The present work is carried out to optimise trisborate buffer as an alternative to barbitone buffer
for use in agarose gel electrophoresis of serum
proteins.
Methods: Tris-borate buffer of strength 0.05M
and pH 8.6 is used for the electrophoretic
procedure. Electrophoresis is run for 21/2 hours at
a current of 3mA/slide. The bands are visualized
by staining with amido schwatz. Patterns in various
disorders are then compared with the patterns
obtained with barbitone buffer.
Results: Comparison of the patterns obtained by
the use of tris-borate and barbitone buffer is
presented.
Similar
numbers
of
electrophoretically distinct components are found
by the use of either buffer. Mobilities of these
components are also comparable.
Conclusion: The similarity in the electrophoretic
pattern and mobility of the components with that
of the classical pattern indicates that tris-borate
can be a suitable alternative for barbitone buffer.

Department of Biochemistry, J. N. Medical College. Belgaum – 590010.
Background: Most of the laboratories use urea
nesslerisation method which was found to be
tedious involving deproteinisation and incubation
for 20 minutes. The estimation of urea by diacetyl
monoxime (DAM) method is very simple and
quick technique of analysis. The reaction between
urea and DAM was established by Fearon in 1935.
Literature have shown many modifications of this
method, by changing the acid concentration,
oxidant ions and use of 4-amino antipyrine,
glucuronate, glucuronate glucosacchric acid,
thiosemicarbazide (TSC) to stabilize the colour.
The reaction occurs between urea and DAM in
presence of strong acid reagent, ferric ion and
thiosemicarbazide (TSC) to give a pink colour and
can be measured colorimetrically. Keeping above
principle, an attempt was made to standardize
DAM method in single step.

All the stock reagents are stored in brown bottle at
room temperature and are stable for 6 months. The
colour reagent is prepared fresh at the time of
analysis by mixing distilled water, mixed acid
reagent and mixed colour reagent in the ratio1:1:1.
This is single step method. The working standards
were taken in respective test tubes, volume was
made to 1ml with distilled water, 3ml of colour
reagent was added, tubes were mixed well and kept
in boiling water bath for 15 minutes, the tubes were
cooled and the pink colour developed was

Objective: Jaundice is most common vexing
problem in new born period. Especially feeding
practice in premature neonates in certain mother
shows long term adverse effect of
hyperbilirubinemia. Hence present study was
undertaken to identify the long term adverse effect
of hyperbilirubinemia in premature neonates, at
different age group (37 to 40 weeks) and birth
weight (0.9 to 3.0 kg) during onset of jaundice.
Methods: A total 70 newborns of the age group 1
to 8 days were selected for study. 35 infants were
on breast feeding and rests 35 were on bottle
feeding. The serum Total and Direct Bilirubin

parameter studied under above heading and is
carried out by Malloy and Evelyn (1937) method.
Results: There was slight decrease in mean value
of total and indirect bilirubin with increase in
gestational age and birth weigh of neonates during
onset of jaundice and mean value of total and
indirect bilirubin found significantly increased in
breast fed neonates of certain mother compared
to bottle fed neonates.
Conclusion: The present study has identified how
certain mothers having 3- á, 20-â- pregnanediol
factor in their milk causes hyperbilirubinemia in
neonates and it is suggested that breast feeding is
to be encourage only in the absence of aggravating
factors such as high milk levels of the steroids and

Novel Therapeutic Properties of Nano Silver*
Siddhartha Shrivastava, Sunil Singh and Debabrata Dash
Department of Biochemistry, Institute of Medical Sciences, Banaras Hindu University, Varanasi-221005
Background: Nanotechnology has been finding
increasing applications in biology and medicine.
Nano silver has already been known to have
antibacterial property. We recently have
synthesized highly stable biocompatible
nanoparticles of silver (10-15 nm diameter) with
enhanced antibacterial effect against gram
negative organisms 1 . Nano silver equally
prevented growth of multi drug-resistant bacterial,
which can have useful clinical application. We
subsequently discovered that nanoparticles of
silver, and not of gold, have innate anti-platelet
property2. They effectively prevent integrin αIIbβ3mediated platelet responses (aggregation,
adhesion to immobilized matrix, secretion of
granule contents, intracellular calcium and F-actin
fluxes, flow cytometric evaluation of surface
epitopes and changes in tyrosine
phosphoproteome) in a concentration-dependent
manner.
Methods: When nanoparticles were intravenously
injected into different mice strains, there was dosespecific inhibition of platelet aggregation, without
any change in tail bleeding. Electron microscopy
218
shows that nano silver accumulates within platelet
granules and reduces inter-platelet proximity.
Results: Our findings further suggest that these
nanoparticles do not confer any lytic effect on
platelets and thus hold immense potential to be
promoted as anti-platelet / anti-thrombotic agent.
Equipped with dual properties (antibacterial and
antiplatelet), nano silver has unique application
potentials in situations like coronary stents, where
it can prevent bacterial infection while keeping
platelets in inhibited state.

Comparison of Various Parameters with Serum Free Light Chain Assay in the
Diagnosis of Multiple Myeloma
Mrudula EV and Dr Sajitha Krishnan
Department of Biochemistry, Amrita Institute of Medical Sciences and Research Center, Kochi;
Background: Multiple myeloma is the second
most prevalent blood cancer after Non-Hodgkin’s
219
lymphoma. It is characterized by excessive
numbers of abnormal plasma cells in the bone
marrow and overproduction of intact monoclonal
immunoglobulins or Bence-Jones protein (free
monoclonal ê and ë light chains).
Objective: To compare the efficiency of serum
free light chain (sFlc) assay with other biochemical
parameters in the diagnosis and prognosis of
multiple myeloma.
Method: 56 patients diagnosed with Multiple
Myeloma at Amrita Institute of Medical Sciences
were included in the study. They were grouped
into two - those with intact immunoglobulin
multiple myeloma (IIMM) and those with light
chain multiple myeloma (LCMM). Biochemical
parameters such as total protein, albumin, globulin,
creatinine were determined by photometric
method in OLYMPUS AU2700, IgG, IgA, IgM,
beta-2 microglobulin, kappa & lambda were
determined by immunoturbidimetric method in
OLYMPUS AU400. Serum protein electrophoresis
of all the patients was done by gel electrophoresis.
Results: IIMM constituted about 56% and LCMM
about 34% of the total MM patients. Among these
patients IgGκ had the highest incidence. In patients
with IIMM sFlc estimation was found to be 78%
effective and in patients with LCMM sFlc
estimation was found to be 95% effective
compared to other parameters.
Conclusion : sFlc can be used as a good diagnostic
test and can effectively replace urine test for bence
jones protein. It can also be used to monitor
patients who cannot be done by electrophoresis
and also help in rapid assessment of treatment
responses. Thus serum free light chain assay along
with other important tests can help in more efficient
diagnosis and disease management in the case of
multiple myeloma.

Importance of Tacrolimus Measurement and Assessment of its Toxicity in
Monitoring Post Liver Transplant Patients
Anuja.P.S, Dr. K.N. Subhakumari and Dr. Jagathlal.P.C
Department of Biochemistry, Amrita Institute of Medical Sciences and Research Center, Kochi.
Background: Over the past 40 years, organ
transplantation has become a rapidly expanding
and important surgical specialty. After liver
transplantation, the main problems encountered
by the patients are rejection of the transplanted
organ and opportunistic infection. So
immunosuppressive drugs are given to post
transplant patients and Tacrolimus is such a drug
which is a powerful immunosuppressant. Side
effects of Tacrolimus can occur and most of these
effects are dose related. In case of Tacrolimus dose
adjustment and change in immunosuppressive
therapy can be done .So estimation of tacrolimus
will be helpful in adjusting the dose. Thus a
sufficient dose of tacrolimus can be given to
patients to prevent rejection and to minimize the
side effects.
220
Objective: Present study was carried out to show
the importance of tacrolimus assay in monitoring
post liver transplant cases and to assess the toxicity
due to Tacrolimus. Objectives of the study include
quantitative estimation of Tacrolimus
concentration in whole blood sample, estimation
of total protein, albumin, globulin, bilirubin, ALP,
ALT, AST, Creatinine, urea, uric acid, glucose,
sodium, potassium and to assess the toxicity using
the above parameters.
Methods: 20 liver transplanted patients below 50
years of age were selected from Amrita Institute
of Medical Science. Six month follow up was done
for each patient. The blood sample was assayed
for Tacrolimus by IMx analyzer using MEIA
method. The liver function tests and renal function
tests of each patient were also noted. Patients were
grouped according to their Tacrolimus
concentration. Group I (0-7 ng/ml) and Group II
(7-15 ng/ml). Then the patient groups were
compared with respect to their renal function and
liver function tests.
Results: A lower incidence of rejection was
observed. In 20 transplanted patients the incidence
of rejection was 20%. In this highest rate of
rejection was seen in group II patients with a
tacrolimus concentration 7-15 ng/ml. This study
also found nephrotoxicity and neurotoxicity in
patients even within the therapeutic range, i.e. in
group II patients. Results were compared using
Mann-Whitney test with the help of SPSS software.
Conclusion: In this study, toxicity was seen even
within therapeutic range. So it is necessary to
determine the concentration of Tacrolimus in the
blood in order to establish a dosing regimen,
maintain therapeutic levels within safe level. So
Tacrolimus assay has to be done throughout the
period of Tacrolimus intake i.e., through out the
lifetime.

implicate the role of P53 in atherosclerotic plaque
stability by repressing vascular smooth muscle cell
proliferation signals. Key polymorphism in codon
72 of p53 contribute to the alteration of its
transactivating domain stability.
Method: Blood samples were collected from the
cardio vascular disease patients and used for lipid
profile analysis. Hyper lipedimic patients, age and
sex matched control patients were selected for the
p53 codon 72 polymorphism study.
Results: Analysis of CAD patients revealed an
significant association between the disease and the
existence of diabetes (P=0.001). Also, the CAD
patients had significantly higher level of
triglyceride (P=0.001) and cholesterol (P=0.001)
as compared to control. The p53 codon 72
polymorphism analysis on hyperlipidemic patients
shows higher percentage of Arg homozygous
genotype and lesser percentage of Arg-Pro
heterozygous genotype. None of the samples
exhibited proline homozygous genotype.
Conclusion: This study concludes that p53 codon
72 polymorphism can be used as a marker for early
diagnosis of hyperlipedimia leading to cardio
vascular disease.

Objective: We prospectively evaluated Silver
nanoparticles as potential antiplatelet /
antithrombotic agents.
Methods: Platelets were isolated from anticoagulated human whole blood sample from fifty
healthy donors. These platelets were suspended
in physiological buffer and each sample was
divided into four tubes, in three of them various
concentrations of prepared and characterized
Silver nanoparticles (SN) were added, fourth tube
served as control (C). Following platelet function
studies were done in all the four platelet samples:
Thrombin induced aggregation (TIA)
Integrin mediated platelet adhesion on
immobilized matrices (IPA)
Integrin mediated cell signaling and associated
cytoskeletal changes- spreading and
degranulation (ICS)
Clot retraction (CR)
Results:TIA was increasingly less marked with
increasing concentration of SN as compared with
224
C. SN showed concentration dependant Thrombin
induced Platelet Aggregation inhibition.
IPA and ICS were also increasingly less marked
with increasing concentration of SN when
compared with C. SN decreased platelet adhesion
and Integrin mediated cell signaling in a
concentration dependant manner.
Similar were the observations for CR. Increasing
concentration of SN resulted in incremental
inhibition of Clot retraction.
Conclusion: Silver nanoparticles appear to be a
potent anti-platelet agent even in low
concentrations. It has the potential for maintaining
a lower activation state for platelets, decreasing
platelet aggregation and their adhesion to Fibrin
clot. With these observations we concluded that
Silver nanoparticles are potential antiplatelet /
antithrombotic agents.
Nano Silver maybe used in therapeutics after
appropriate trials and can find a place among antiplatelet agents in use now.

Introduction: Cardiovascular autonomic diabetic
neuropathy (CADN is one of the most clinically
significant complications of diabetes mellitus
(DM), but one of the least frequently diagnosed.
The pathophysiology range from genetic disorders
with specific gene defects to metabolic disorders
with accumulation of toxins and to autoimmune
disorders. An increased level of micronuclei has
been shown to be marker of chromosome damage.
Methods: Present study was undertaken to
quantify the extent of somatic DNA damages by
cytokinesis-block micronuclei (CBMN) assay in
subjects suffering with CADN and to asses the
various socio-economic, demographic
characteristics. Forty six subjects suffering from
autonomic neuropathy formed the study groups.
All the subjects were suffering from diabetes for
atleast 8 years and have varying degrees of
coronary artery diseases. Twenty five healthy age
and sex matched control subjects were selected.
Two to three ml of venous blood was collected
aseptically in heparinized vacuutainers and CBMN
assay was performed.
Results: The mean CBMN frequency of 15.21 of
the study subjects was significantly higher than
the CBMN frequency of 10.6 observed in the
control subjects (P<0.05). The mean CBMN
frequency in patients with CADN with respect to
various risk factors such as dyslipidemia,
hypertension, smoking, chewing, and drinking
showed increased level of somatic damage.
Conclusion: This study clearly demonstrated an
increased level of somatic damages in CADN
patients which was found to be increasing with
risk factors associated with life style and duration
of diabetes.

Computational Studies of the Interactions of Some Inhibitors with HIV-1 Protease
Rajkumari Rathore, Savita Rathore, Neha Sharma and Anil Bidwai
Department of Biochemistry, Index Medical College, Indore, MP; Email: [email protected]
Background: Structure-based design has been an
integral player in molecular research for over a
decade. HIV-1 protease (HIV-1 PR) is an
important target for structure-based inhibitor
design of anti-HIV drugs. This enzyme cleaves
gag and gag-pol proteins to produce structural and
functional proteins in the virus. It has been shown
that inhibition of this process produces noninfectious virions. HIV-1 PR is a homodimer, with
230
each monomer contributing an aspartic acid to the
catalytic dyad. Two flexible flap regions cover the
ligand upon binding. Inhibitors of HIV-1 PR are
widely used in the treatment of HIV/AIDS.
However, due to the rapid development of drug
resistance of the virus and side effects encountered
upon treatment, new inhibitors of HIV-1 PR are
constantly needed.
Objective: This study was undertaken with the
objectives to understand structural features that
contribute to the interactions of ligands with HIV1 PR and to elucidate the mechanisms of these
interactions.
Methods: In this study interactions of three
potential inhibitors of HIV-1 PR, namely aha024,
xk2 and cu216, were analysed using
computational docking methods. A computational
docking program, AutoDock, was used to carry
out the simulations. AutoDock uses a Monte Carlo
simulated annealing technique for configurational
exploration with rapid energy evaluation using
grid-based molecular affinity potentials. Aha024
docked with a minimum docking energy of -19
kcal/mol, rmsd = 0.78 ú and an inhibitor constant
of 1.1x10-10 M. The respective values for xk2 were
-25 kcal/mol, 0.76 ú and 4.7x10-15 M and those for
cu216 were -15 kcal/mol, 0.59 ú and 1.5x10-8 M.
Results: Results of docking with these
peptidomimetic inhibitors show that the ligands
bind in an extended manner: the transition state
isosteres bind at the catalytic dyad and the residue
side chains occupy pockets on alternate sides of
the backbone. The amide bonds engage in a series
of hydrogen bonds with the enzyme, and also with
a conserved water molecule (H2O 301) positioned
between the flap regions and the ligand. This key
binding mode difference can provide a unique
strategy for nonpeptide inhibitor design

Auto Antibody in The Cases Of Neurological Disorder
Dr.Anand Saran*,Mr.S.S.Haque*,Dr.Ashok Kumar** and Dr.Uday Kumar*
*Dept. of Biochemistry,IGIMS,Patna, ** HOD,Dept. of Neurology,IGIMS,Patna
Background: An autoantibody is an antibody (a
type of protein) manufactured by the immune
system that is directed against one or more of the
individual’s own proteins. Antibodies are normally
produced in response to a foreign protein or
typically a pathogen, which is a infectious
organism. Normally, the immune system is able
to recognize and ignore the body’s own cells.
Sometimes, however, the immune system ceases
to recognize one or more of the body’s normal
constituents as “self,” leading to production of
autoantibodies. These autoantibodies attack the
body’s own cells, tissues or organs. The causes of
autoantibody production are varied and not well
understood. It is postulated that :- 1. Due to a
genetic predisposition, 2. Environmental
trigger,such as a viral illness or a prolonged
exposure to certain toxic chemicals, 3. A hormonal
component. A diagnosis of disease can not be
made solely due to detection of Autoantibody
Methods:The diagnosis starts with a complete
medical history and a thorough physical
examination and by observing signs and
symptoms. A number of diagnostic studies is
required to identify a specific disease. Viz. 1.Blood
tests to detect inflammation, autoantibodies, and
organ involvement 2.X-rays and other imaging
scans to detect changes in bones, joints, and organs.
3.Biopsies to look for pathologic changes in tissue
specimens.
Results: Antibodies against muscle or neuronal ion
channels, and against myelin glycolipids are
clearly associated with peripheral neurological
diseases. Some of these antibodies are also being
identified in central nervous system (CNS)
disorders. In this article we present autoantibody
of significance in Neurological disorder and
various methods of its estimation.

Medical Sciences, Tirupati, Andhra Pradesh, India, Email: [email protected]
Background: An altered immune status has been
found in Type 2 diabetes mellitus (T2DM).
Adenosine deaminase (ADA), has the highest
activity in T-lymphocytes, and is a well known
marker of CMI. Type 2 diabetes is associated with
systemic low-grade inflammation, and ADA
which mediates an inflammatory response is
considered an inflammatory marker. Adenosine,
the substrate for ADA enhances the effect of
insulin action on glucose transport and in the
presence of elevated ADA activity, this effect of
Adenosine is lost. Dyslipidemia commonly
observed in diabetes, is a well established
traditional risk factor for cardiovascular disease
(CVD). The present study was taken up to evaluate
serum ADA activity and lipid profile in T2DM.
Methods: 25 patients diagnosed as T2DM within
the preceding 2-3 months and 25 age and sex
matched healthy individuals were taken into the
study. Serum ADA was estimated by the method
of Galanti and Giusti using Perkin Elmer UVSpectrophotometer. Fasting blood sugar,
cholesterol, triglycerides, HDL were estimated on
Beckman Synchron CX9 autoanalyzer. VLDL and
LDL were calculated using Friedewald’s formula.
The differences in the means of the biochemical
parameters were analyzed using unpaired student’s
t test.
Results: Significant increase in serum ADA,
cholesterol, triglycerides, LDL, VLDL and a
decrease in HDL were observed in T2DM patients
when compared to controls.
Conclusion: Elevated serum ADA activity may
be an important marker of an altered immune status
even in early onset T2DM, and also indicates an
inflammatory state. Diabetic dyslipidemia
increases the risk of CVD.

Background: The implementation of DEC based
mass drug administration (MDA) has created need
more than in the past, for the novel filarial tests to
monitor the treated population and to assess the
transmission of infection. Recombinant filarial
antigens with higher specificity are expected to
be superior to native antigens and also help to
overcome the practical difficulty in getting suffi232
cient quantity of antigen material.
Methods: Recombinant fialarial antigen WbL2
has been identified by immunoscreening
W.bancrofti cDNA library with microfilariaemic
sera. Monospecific polyclonal antibodies were
raised against rWbL2 in BALB/c mice. Filarial
antigen and antibody assays were developed us-
ing rWbL2, antibodies raised against it and IgG
fraction of human clinical filarial serum (IgG). A
total of 90 sera samples belonging to different filarial groups were screened.
Results: Filarial antigen assays using anti rWbL2
antibodies alone or in combination with FSIgG
were 100% specific,but yielded low sensitivity of
only 40% and 60% respectively to detect
microfilariaemic cases. In contrast the filarial IgG4
antibody assay using rWbL2 antigen detected all
the 25 microfilaraemic cases screened giving 100%
sensitivity with 100% specificity. However this
assay also picked up some of the exposed / prepatent infections by detecting 16% of the endemic
normals screened.
Conclusion: Recombinant WbL2 antigen based
filarial IgG4 antibody assay provides a useful tool
to detect infected cases for the prompt initiation
of anti filarial therapy and for survelliance of elimination programme

Background: Tuberculosis has been a major
health problem for developing countries including
India. Multi-Drug Resistant Tuberculosis (MDRTB) is a growing hazard to human health
worldwide and threat to control of tuberculosis.
Current estimates report the prevalence of primary
and acquired MDR-TB in India as 3.4% and 25%
respectively. In the last two decades, the AIDS
epidemic and the deadly synergy between
Mycobacterium tuberculosis and HIV have
favored the recrudescence of microbial infections
throughout the world. The current recommended
strategy for microbial infections is facing two
problems: Multi Drug Resistance (MDR) and
HIV/AIDS pandemic. Additionally, in patients
with impaired cellular immunity (HIV-syndrom),
mycobacterial and fungal (Aspergillus,
Histoplasma, etc.) infections predominate and
may coexist. Emergence of multi-resistant strains
of bacteria has increased the problem of drug
resistance dramatically. Every country in the world
has drug resistance bacteria.
Objective: The development & use of new antimicrobial agents is one of the ways to combat the
emergence of antimicrobial resistance. Synthesis
of heterocyclic compounds to explore the potential
biologically active agents still draws continued
interest. Hence the different aldehydes substituted
5-methyl pyrazine/ pyrazine-2-carbohydrazide
derivatives were prepared and tested for its
immuno modulatory and respiratory burst killing
activity.
Results : The derivatives PH 9, PH 13, PM 2, PM
5, PM 6, PM 14 have been found to be more
promising amongst the compounds tested as
compared to the –ve control.

*Associate Professor Dept of Biochemistry,SCB Medical College, Cuttack, ** Professor of Medicine,
VSS Medical College, Burla; Email-id : [email protected]
Objective: Studies indicate lactate level as an
accurate prognostic indicator and major cause
of death in children with severe malaria.This study
was undertaken to assess serum lactate levels in
various subsets of severe malaria and its
prognostic importance in adults.
Methods: Adult patients of severe malaria were
examined and classified as :
Cerebral Malaria(CM), n = 29
Non Cerebral Severe Malaria(NCSM), n = 58
Muti Organ Dysfunction(MOD) – classified as
involvement of two or more organs, n = 36
Two control groups were
Uncomplicated falciparum infection (UM), n = 64
Endemic Normals (EN), age and sex matched, n = 10
Venous blood collected was used for routine and
biochemical tests. Serum lactate was estimated
by endpoint colorimetric method.
Results: Mean control values for EN and UM were
24.4 ± 7.03 mg/dl and 37.01 ± 25.5 mg/dl
respectively. In comparison value for CM was
43.8 ± 24.3mg/dl, NCSM was 39.5 ± 28.6 mg/dl
and MOD was 58.5 ± 92.3. The values for UC
and subsets of severe malaria were significantly
high(p < 0.01) compared to EN. There was no
significant difference of lactate values between
different subsets of falciparum infection (p > 0.05)
although values were highest in MOD. The mean
lactate levels in survivors was 40.7 ± 29.2 mg/dl
compared to 87.7 ± 143.1 mg/dl in those who died
but the difference was statistically
insignificant(p<0.24). Correlation between serum
creatinine and lactate was positive (r = 0.11).
Conclusion: Serum lactate levels in adult
falciparum infection in Orissa has insignificant
prognostic value contrary to observations made in
other parts of the world.

Background: Tuberculosis (TB) remains one of
the world’s leading infectious causes of death
among adults. Every year, approximately 2 million
persons in india develop tuberculosis (TB),
accounting for one fourth of the world’s new tb
cases. Acute phase protein (APP) are a class of
diverse proteins whose blood plasma
concentration increases or decreases during the
response to inflammation, in the acute phase.
Objective:Therefore, the present study was
planned to know whether there is relationship
between serum ferritin and haptoglobin with
hemoglobin in anemic pulmonary tuberculosis
patients when compared with healthy control of
the same age group (20-58yrs) and sex.
Methods: A prospective study was carried out in
40 newly diagnosed patients with anemic
pulmonary tuberculosis at Sri Aurobindo Institute
of Medical Sciences & from the dots centre, indore.
Normal control subject (n=35) were recruited for
the study. Serum haptoglobin and ferritin levels
were estimated by ELISA method & hemoglobin
by cell counter (sysmex kx-21).
Results: The above study revealed that there is
significant increase in serum haptoglobin & ferritin
levels with decrease in hemoglobin concentrations
when compared with healthy controls. The study
suggests that ‘rise in acute phase protein causes
disturbance of iron homeostasis which leads to
anemia.’

Anti - CCP Auto Antibodies in Rheumatoid Arthritis
Vinod AN*, Nalini Ganesan* and Rajasekar#
Department of Biochemistry*, Rheumatologist#, Sri Ramachandra Medical College and Research
Institute, Sri Ramachandra Medical University, Porur, Chennai. India
Background: Rheumatoid arthritis (RA) is a
chronic inflammatory arthritis with potential to
cause significant morbidity and mortality. It is
important to diagnose RA at a very early stage in
the disease. Serological tests are important in
diagnosing rheumatic diseases. To facilitate
diagnosis during the early stages of the disease a
good serological marker is needed. Besides the
rheumatoid factor (RF), another group of auto
antibodies has recently been detected in serum of
236
patients with RA. Anti – CCP antibodies are
undoubtedly among the most interesting antibodies
to have been identified in recent years. Auto
antibodies directed against citrullinated proteins
have a much higher specificity for RA. These
citrullinated proteins have been detected in the
synovium of RA patients. Citrulline is a non
standard amino acid being formed as a result of
post translational modificational change of protein
bound arginine by peptidyl arginine deaminase.
Our previous studies on the serum biochemical
marker of RA reports 56% of RF positivity in a
group of rheumatoid arthritis patients. Several
observations have indicated that anti-CCP positive
in early RA patients may develop a more erosive
disease than those without anti – CCP. In this
review we will discuss the process of formation
of citrullinated protein, its transformation to auto
antigens and the clinical utility of these auto
antibodies.
Objective: We have planned to estimate the anticcp antibodies in the RA patients (early, established
and late disease) to study our observations on the
clinical utility of this autoantibody in RA.

Bhopal Memorial Hospital & Research Centre, Raisen Bypass Road, Bhopal
Background: Fertility regulation with plant
preparation/medicaments has been mentioned in
ancient texts of indigenous system of medicine.
The major advantage of the use of herbal drugs,
being non-steroidal is that they have least side
effects, having low toxicity potential for human
use in the history of folklore medicaments and
more importantly cost effective. Plant derived
compounds or their derivatives are the basis of a
large number of established drugs. Approximately
80% of the world’s population depends on healthcare system that involved the use of traditional
medicine, medical plants, including fertility
regulating plants, are integral part of such
practices. The seed product of Carica papaya has
shown promising results in proving contraceptive
effectiveness in animal models. However,
concerted efforts at a molecular level to decipher
the mode of action of the drug have yet not been
established.
Objective: To elucidate the molecular
mechanisms of the contraceptive effects of Carica
papya seed products for developing a plant based
oral pill for male contraception.

to Combination Therapy: A Pilot Study from Central India
P. K. Mishra, A. Bhargava, R. P. Punde, S. Tiwari, P. Vashistha, S. Varshney and K. K. Maudar
Bhopal Memorial Hospital & Research Centre, Bhopal, India
Background: HCV infection is a worldwide
public health problem and is a major cause of
hepatic fibrosis, cirrhosis, end-stage liver disease
and hepato-cellular carcinoma. Till date 6 different
HCV genotypes and more than 70 sub-types based
on the nucleic acid sequences have been identified.
Due to such high levels of genetic heterogeneity,
treatment options for HCV infections are poor. At
the moment, the only accepted antiviral therapy
with proven effectiveness is a combination therapy
of (pegylated) interferon alpha and ribavirin.
Moreover, the precise immune response against
HCV genotypes and their region specific
prevalence in central India is unknown and the
impacts of viral load, genotype, and immune
mediators on the clinical course are poorly defined.
Thus, in order to refine the current knowledge of
treatment strategies there is an ongoing need to
evaluate the influence of host and viral factors.
Aim: The objective of present study was to
perform a clinical, epidemiological and
immunological characterization of chronic
hepatitis C infection in a cohort from central India.
Methods: A total of 34 patients suffering from
chronic HCV were included in the study. Response
to combination therapy (IFN-R) was classified as
rapid virological response (RVR), defined as
undetectable HCV RNA at week 4 after the
initiation of combination therapy; early virological
response (EVR), defined as undetectable HCV
RNA at week, 5 to 12 of combination therapy;
238
and late virological response (LVR), defined as
undetectable HCV RNA after week 13 of
combination therapy. A SVR was defined as
clearance of HCV RNA (<600 IU/ml) at 6 months
after the cessation of combination therapy.
Detection of HCV RNA was done through COBAS
AMPLICOR Analyzer (minimum detection limit
600 IU/ml). Genotypic characterization of HCV
was done using Linear Array HCV genotyping test
kit from Roche Diagnostics, Mannheim, Germany.
Analysis of secreted levels of inflammatory
cytokines was performed using BDTM Multiplex
Cytometric Bead Array (CBA) Human TH1/TH2
kit from BDTM Biosciences, San Diego, USA.
Results: The prevalence of genotype 3 was found
in 91.18 % cases while 28.8% were found to be
infected with genotype 1. In genotype 3 infected
patients RVR, EVR and SVR were observed in
74.19 %, 16.12 % and 9.6 % respectively. While
in patients infected with genotype 1 RVR and LVR
was observed in 33.33 % and in 66.66 % patients.
With an intention to treat analysis 100 % and 66.6
% SVR was observed in genotype 3 and 1
respectively. However, SVR was not observed in
1 patient out of 3 in genotype 1 infected population.
A significant increase in the levels of Th1

Diagnosis of Mycobacterial Tuberculosis Complex (MTBC) in Endoscopic Biopsy
Samples and Paraffin-Embedded Tissue Specimens Using Real Time PCR:
Implications in Patient Care
G. V. Raghuram, A. Bhargava, R. P. Punde, S. Varshney, K. K. Maudar and P. K. Mishra
Objective: The diagnosis of Mycobacterium
tuberculosis complex (MTBC) in endoscopy
biopsy samples and formalin-fixed, paraffinembedded surgically resected tissues of the gastrointestinal tract remains a complex issue because
the most widely used conventional diagnostic
tools, such as culture and acid fast bacilli staining
are unable to rapidly detect Mycobacterium
tuberculosis with sufficient sensitivity. Using
fluorescence resonance energy transfer (FRET)
technology based on hybridization probes, we
applied a novel technique consisting of an
internally controlled quantitative real-time PCR
assay that provided a significant improvement in
detection sensitivity and quantification.
Methods: The study included three groups (A)
control (n=24) with no previous signs of MTBC,
(B) patients (n=28) with known TB origin and (C)
patients (n=50) with clinical and histopathological signs of TB but was culture and AFB
negative. The samples were obtained from
Medical & Surgical Gastroenterology
Departments of Bhopal Memorial Hospital &
Research Centre. We extracted DNA using
DNeasy Blood & Tissue kit (QIAGEN, Germany)
and performed Real time assay using Roche Light
Cycler 2.0 with FRET probes for specific
amplification of 159 bp region of mycobacterium
genome.
Results: All the samples (n=24) of group A were
found to be negative, while in group B out of total
28 cases studied 27 were found to be positive by
real-time PCR. In group C out of total 50 cases
studied 18 were found to be positive showing a
positivity of 36 %. The overall positive and
negative predictive values of the test for clinical
TB (group C) were 100 % and 96.9 % respectively.
Conclusion: Results of our investigation exhibit
that the real time detection technology using FRET
probes, has much higher sensitivity for the
detection of Mycobacterium tuberculosis complex
DNA in tissue biopsy samples and formalin-fixed
paraffin embedded surgically resected tissues of
the gastro-intestinal tract. However, to establish
the superiority of this novel technique for MTBC
diagnosis in various latent infectious states, it will
be necessary to accumulate data from a larger
number of patients with suspected tuberculosis
infection

Mediators of Immune System and Their Possible Role in Pathogenesis of Chronic
Hepatitis B and C Viral Infections
R. P. Punde, A. Bhargava, S. Gupta, S. Varshney, P. Vashistha, K. K. Maudar and P. K. Mishra
Background: The circulating inflammatory
biomarkers may contribute to the pathogenesis of
chronic viral hepatitis infections. The present
study was carried out in order to evaluate the levels
of circulating biomarkers in the patients with
chronic viral hepatitis of different aetiology and
their possible role in the pathogenesis of the
disease.
Methods: The study was divided into 3 groups
i.e. group 1 comprise of patients with chronic
HBV infections (n=60), group 2 included patients
with chronic HCV infections (n=60) while group
3 consist of healthy age and gender matched
controls (n=60). The mean age of all the subjects
in the study was 35 years. Total viral load was
quantified from the EDTA plasma and correlation
studies were performed with circulating Th1/Th2
cytokines; levels of C reactive protein (CRP);
glutathione reductase (GR) and superoxide
dismutase (SOD) and levels of circulating
nucleosomes.
Results: A strong positive correlation of Th2
cytokines and GR with viral load in HBV and HCV
was observed. The levels of circulating apoptotic
nucleosomes also correlated with viral load.
However, no significant correlation with CRP and
SOD was observed.
Conclusion: These results can be helpful in
designing interventional strategies like anti-viral
therapeutic and/or immunotherapeutic strategies
to prevent the progression and long term
consequence, as well as for effective prevention
of chronic infections and thereby contributing
towards developing personalized medical care

in Multiple Myeloma and Study of Complications in Multiple Myeloma
Dr. Sajitha Krishnan and Toni Thomas
Department of Biochemistry, Amrita Institute of Medical Sciences, Kochi.
Background: Multiple myeloma is a chronic,
progressive and fatal malignant condition in which
the fundamental abnormality is a neoplastic
proliferation of plasma cells, which infiltrate the
bone marrow and often other body tissues. The
disease affects man kind almost universally. It
representing approximately 1% of all types of
cancer. Serum protein electrophoresis is the most
commonly used diagnostic tool for this disease.
Objective: The objective of this study was to
evaluate electrophoresis and immunochemical
240
quantification of serum IgG IgM & IgA in the
diagnosis of multiple myeloma and to study the
complication of multiple myeloma with the help
of parameters like Total protein, albumin, globulin,
A G ratio, Creatinine, Serum Alkaline Phosphatase
Serum calcium and Serum LDH.
Methods: The study was carried out at department
of biochemistry AIMS, Cochin during the period
January 2008 to January 2009. Electrophoresis was
carried out for the blood samples come with order
of serum protein electrophoresis.45 M band
positive (monoclonal protein present) blood
samples were selected and performed
immunochemical quantification of serum (IgG
IgM & IgA) ,Total protein, albumin, globulin, A
G ratio, Creatinine, Serum Alkaline Phosphatase
Serum calcium and Serum LDH.
Result: Of the 45 M band positive patients, 28
(62.22%) patients of them showed an increase in
IgG, 2(4.45%) showed an increase in IgM,
4(8.89%)patients showed elevated levels of IgA,
and 11 (24.44%) of them showed low levels of
Immunoglobulins(IgG, IgM, IgA). In the study
group, about 44% showed increased protein levels,
62% patient’s serum globulin levels were above
normal.About 42.5% patients showed low serum
albumin levels. The A/G ratio was reversed in
about 75%. 35.5% of the patients showed an
increase in serum creatinine. Among the creatinine
elevated patients, 75% of them were under IgG
type Myeloma group & about 6% were under IgA
type Myeloma and 19% of them in the Light chain
multiple myeloma group. Of the 45 patients about
33.33% of the patients have high serum ALP level.
About 60% high ALP values belonged to IgG
myeloma group, about 13.34% belonged to IgA,
and the rest 26.66% belonged to light chain
multiple myeloma group. High Serum Lactate
dehydrogenase (LDH) is seen in 57.14%
patients.Of the 57.14% LDH elevated patients,
75% high LDH values belonged to IgG myeloma
group, about 12.5%belonged to IgA,
6.25%belonged to IgM Myeloma and the 31.25%
belonged to Light chain multiple myeloma group.
Calcium levels were increased in less than 10%
patients. Among the hypercalcemic patients 50%
were in light chain myeloma.
Conclusion: Serum protein electrophoresis is not
sufficient to diagnose multiple myeloma because
the position of the band only suggests the type of
antibody. Serum protein electrophoresis alone will
be insufficient especially if the multiple myeloma
is of non-secretory type. In such cases urine protein
electrophoresis should be done to detect the light
chain produced. Immunoturbidimetric quantitative
measurement of immunoglobulin levels used along
with serum protein elcetrophoresis can be used as
a confirmatory test in the diagnosis of myeloma.
So a combination of serum protein electrophoresis
and immunoturbidometric quantitative estimation
of gammaglobulins along with clinical symptoms
can be used as tools for diagnosis of different kinds
of multiple myeloma and to classify it. In the
present study it has been noted that IgG myelomas
showed the highest prevalence rate. Moreover,
complications in myeloma were also maximum in
the IgG myeloma class. This may be due to the
greater percentage of IgG producing B-cells in the
human body. Thus these B-cells have a greater
tendency to be affected by myeloma.

Role of GST Polymorphisms in the Susceptibility and Outcome in Acute
Lmphoblastic Lukemia
KJ Suneetha, K Nirmala Nancy, KR Rajalekshmy, TG Sagar and T Rajkumar
Background: ALL is the most common pediatric
malignancy constituting about 30% of childhood
cancers. The origin of this disease may be
explained by a combination of genetic and
environmental factors. The glutathione S
transferase family is involved in the metabolism
of a wide range of chemicals including
environmental carcinogens, reactive oxygen
species, and chemotherapeutic drugs.
Polymorphisms in GST enzymes have been
implicated in the susceptibility and outcome in
several cancers.

polymorphisms.
Results: We found a significant increased risk for
ALL with the GSTM1 null genotype (OR: 1.96,
95%CI=1.08-3.57). Though GSTP1 by itself is not
associated with the susceptibility to ALL, when it
is combined with GSTM1, a significant increase
in risk has been observed (OR=2.78: 95%CI=1.166.69). Kaplan Meier survival analysis shows

Departments of Neurosurgery*, Anesthesia** & Biochemistry***, Narayana Medical College, Nellore-2, A.P
Background: There have been only few studies
to estimate the normal ionic magnesium levels in
the CSF in human beings. Role of serum ionic
magnesium has been studied in various
cardiovascular, obstetrics and neurological
disorders. Before estimating CSF ionic
magnesium levels in various neurosurgical
disorders we wanted to establish normal range of
ionic magnesium in the CSF.
Methods: Patients undergoing lumbar puncture
for anesthesia and suspected neurological
disorders were included in the preliminary study
(with ethics committee approval and patient
consent). CSF (about 0.5ml) was collected from
these patients and sent to the lab where the ionic
levels of calcium and magnesium were estimated
along with total levels. Total Ca++ and Mg++ were
measured by photometrically.The ionic Ca ++
measure by ion selective method. The ionic Mg++
measured by atomic absorption spectrophotometer.
Results: CSF was collected from 15 patients
undergoing LP for spinal anesthesia. The average
value of CSF total calcium and magnesium was
5.4mg% (2.64meq/L) and 2.7mg % (2.22meq/L).
The average ionic concentration of calcium was
1.38 meql/L for calcium and 1.96 meql/L for
magnesium. The ionic magnesium level accounts
for significant amount of total CSF magnesium.
Conclusions: Our preliminary data suggests that
ionic magnesium and ionic calcium contribute to
significant proportion of total CSF values.

Background: Parkinson’s disease (PD) is a
progressive neurodegenerative disorder
characterized by selective degeneration of
dopaminergic neurons in substantia nigra (SN)
pars compacta leading to marked reduction of
dopamine (DA) levels in the striatum.
Method: The present study analysed the effect of
neurotransmitters as treatment on rotenone
induced hemi-Parkinson’s disease in rats and its
244
role in the regulation of DA D1 receptor in the
corpus striatum (CS) and cerebral cortex (CC) of
the experimental rats. Unilateral stereotaxic single
dose infusions of 1 µl of rotenone (8µg/µl) were
administered to the substantia nigra of adult male
Wistar rats. Neurotransmitters –serotonin (5-HT),
dopamine and norepinephrine (NE) treatments
were given to rotenone induced hemi-Parkinson’s
rats.
Result and conclusion: Scatchard analysis of DA
D 1 receptors showed a significant decrease
(p<0.001) in the CS and a significant increase
(p<0.001) in the CC in the PD rats compared to
control. These altered parameters were reversed
to near control in the 5-HT and NE treated PD
rats and no change was observed in DA treated
PD rats. Real-time PCR results confirmed the
receptor data. Cognitive and sensorimotor
activities were reduced in PD rats which were
reversed by 5-HT and NE. Our results showed 5HT and NE functionally reversed in DA D1
receptors in rotenone induced hemi-Parkinson’s
rat. This has clinical significance in the therapeutic
management of Parkinson’s disease.

Acute Ischemic Stroke
J. Sudha Rani
Assistant Professor, Dept of Medical Biochemistry, GVP Biomedical Engineering College for Women,
Visakhapatnam, AP.
Objective: Oxidative stress is probably involved
in neuronal damage induced by ischemiareperfusion. The present study was designed to
measure the enzymatic and non enzymatic
antioxidant status following acute ischemic stroke
patients with large vessel and small vessel infarcts.
Methods: The study included 72 subjects in which
30 were controls and 42 were acute ischemic
stroke cases. They were diagnosed basing on
clinical manifestations and by CT scan of the brain.
The cases were further divided into 2 groups. The
ischemic stroke patients with large vessel infarcts
(Group-L) and small vessel infarcts (Group-S)
based on CT scan of the brain. Serum enzymatic
antioxidants (superoxide dismutase and
glutathione peroxidase) and the non enzymatic
antioxidants (reduced glutathione, vitamin E and
vitamin C) were estimated in all the subjects by
using spectrophotometer.
Results: Ischemic stroke cases had significantly
lower levels of enzymatic and non enzymatic
antioxidants, compared to controls which is
statistically significant (p<0.05). The Group L
ischemic stroke cases had statistically significant
(p<0.05) lower levels when compared to Group S
ischemic stroke cases.
Conclusion: The antioxidant activity of serum may
be an important factor providing protection from
neurological damage caused by stroke-associated
oxidative stress. The present study suggest that
reduced antioxidant status may be used as an
indirect evidence of oxidative stress induced
neuronal damage in acute ischemic stroke which
may be useful for monitoring and optimizing
antioxidant therapy.

Blood Glucose in Small for Gestational Age Infants
Arvindkumar Chowdhary, R Nisarga, C S Muralidhara Krishna and K L Mahadevappa
Dept. of Pediatrics and Dept. of Biochemistry, Kempegowda Institute of Medical Sciences, Bangalore.
Background: Small for gestational age (SGA)
babies have a higher metabolic rate than the
appropriate for gestational age (AGA) infants of
the same size and are more prone to hypoglycemia
that can result in brain damage,mental retardation
and cerebral palsy.
SGA female infants—50.00mg%
Methods: Present study is an assessment of the
frequency of hypoglycemia and its clinical
manifestations in SGA neonates. Singleton live
born babies, born at KIMS Hospital, who were
below the tenth percentile were taken as SGA
infants. Randomely chosen 200 cases each of SGA
& AGA infants in which 52% were male, 54.5%
were of gestational age of < 37 weeks and 50%
were in the birth weight ranging from 15002400gs. Blood sugar was estimated on a routine
chemistry analyser in cord blood just after birth
and cubital venous cord blood at 2—3hrs, 6hrs,
12hrs and 24hrs of life.
Mean blood glucose level at 0 hr of age is nearly
normal in both SGA and AGA babies but the
glucose level falls to hypoglycemic levels within
2-3hrs of extrauterine life more commonly in SGA
babies (46.02 mg% in SGA babies as against 51.62
mg% in AGA babies).Hypoglycemic babies
presented themselves with signs and symptoms
such as lethargy, convulsions, apnea, refusal to
feed, tachycardia, jitteriness and the state of
collapse.
Resulst: Mean blood sugar level at 0 hr and 2—
3hrs of age in different groups is as follows: 0 hr2—3hrs, SGA preterm infants— 51.90mg% —44.75 mg%
SGA fullterm infants— 54.13mg% — 47.07 mg%
SGA male infants — 55.00mg% — 47.00 mg%
— 44.oo mg%
SGA infants weighing less than 1500gs
52.77mg% —46.15mg%
—
SGA infants weighing more than 1500gs —
53.07mg% —46.01mg%
Conclusion: Thus the study suggests
that screening of all babies for hypoglycemia at 0
hr, 2-3hrs, 6hrs, 12hrs and after, if necessary, of
birth should be mandatory and babies at the risk
of developing hypoglycemia should be identified.
Early intervention with 10% dextrose helps to
alleviate the neurological sequale and prevents the

Associate Professor, Pharmacology, KMC,
Methods: One hundred and five diabetic patients
receiving treatment were seen over a period of one
year. Among these, patients with diabetic
nephropathy, retinopathy, diabetic ulcers and
urinary tract infections were segregated. Fasting,
postprandial blood sugar (monthly) and
glycosylated hemoglobin (once in three months)
were estimated. The analysis was carried out by
means of Graphpad statistical package.
Results: A total of 60 patients had the above
complication (15 each). The average duration of
the diabetes was 8.65± 1.26, 10.37± 1.25,
13.23±1.75 and 8.86±0.87 years respectively in
patients with diabetic retinopathy, nephropathy,
diabetic foot ulcers and urinary tract infections.
We found that the highest FBS, PPBS and
glycosylated hemoglobin was seen in patients who
had diabetic retinopathy (160.67±10.32,
221.50±9.0, 8.04±0.87 respectively). The lowest
values were seen with urinary tract infection
(144.17±11.0, 213.50±5.68, 7.77 ±0.47). There
was a statistically significant difference between
these groups (p<0.05). The re was no much
difference between the other two parameters.
Conclusion: - We conclude from our study that
urinary tract infections are commonly seen with
earliest alternation of blood sugar. Retinopathy was
seen in patient with high blood sugars and
glycosylated hemoglobin values though it has
manifested early compared to other complications.

Methods: Seventy patients (aged 35 – 70 years)
with history of 5 – 15 years of type II diabetes and
on treatment with oral drugs (metformin,
glibenclamide, etc..) and 35 age matched healthy
controls were the subjects of this study. Blood
samples were collected after keeping the
individuals on overnight fast. Serum samples were
estimated for triacylglycerol, total cholesterol and
HDL cholesterol by enzymatic methods using kits.
VLDL and LDL cholesterol were calculated by
using Friedewald formula.
Results: The diabetic patients had relatively higher
fasting and post - prandial blood glucose levels
compared to controls. Serum triacylglycerol, total
cholesterol, VLDL and LDL cholesterol
concentrations were also higher in diabetics
compared to healthy individuals. Further, serum
HDL concentration was lower in diabetics when
compared to controls.
Conclusion: It appears from this pilot study that
type II diabetics of low socio - economic group,
mainly depending on the government general

Background: Unfortunately India topped the list
of diabetic population. In the recent years, raised
oxidative stress (OS) has been claimed as one of
the significant risk factors. The two main proposed
hypotheses are: a) raised OS can trigger DM by
inducing insulin resistance which is a cardinal feature of DM and b) hyperglycemia raises OS which
exacerbate multiple risk cascade resulting in diabetic complications. Our observations do not unequivocally support either of these claims.

DM or associated complications.
Methods: The study included 209 diabetic patients
(Type 1-70 and Type 2-139) and 131 matched controls. Serum/RBC lipid peroxidation levels (LPO
expressed as nmol/ml), and antioxidant complement was examined.
Results: LPO levels were raised in diabetics
(4.95±2.19) as compared to controls (2.88±1.29),

findings are a) in none of the groups all patients
had raised OS b) DM with complications did not
show raised LPO levels than those without complications c) mean GSH levels were slightly but
significantly lower in patients but neither it could
be categorized as depleted or low d) Antioxidant

Methods:
The
thyroid
hormones,
Tetraiodothyronine, Tri iodothyronine, and
Thyroid Stimulating Hormone were estimated in
cord blood. The thyroid function tests were done
by the ELISA method, the blood glucose by
glucose oxidase-peroxidase method and glycated
haemoglobin by the cation exchange resin method.
Results: In the present study the tri iodothyronine
levels in cord blood were found to be much higher
than normal range. Normally the triiodothyronine
levels are lower in cord blood (4-141 ng/dl) as
compared to the adult (70-207 ng/dl).
Triiodothyronine levels in cord blood also
showed a statistically significant positive
correlation with the severity of maternal diabetes
as judged by post prandial blood sugar levels and
Discussion: The increase in Triiodothyronine
levels in cord blood may be due to foetal
hyperglycaemia and the resulting foetal
hyperinsulinsm. In the mother when the blood
glucose levels are high the intracellular entry of
glucose is low due to insulin resistance. The foetus
of a mother with gestational diabetes is exposed
to hyperglycemia due to transplacental transfer of
maternal glucose .This stimulates the foetal
pancreas to produce more insulin. In the
foetus,there is no insulin resistance and the increase
in both glucose and insulin levels facilitates the
entry of more glucose into the foetal cells which
may enhance the activity of 5’ deiiodinase causing
increased formation of T3 from T4.This may be the
reason for increased T3 levels in cord in correlation
with maternal hyperglycemia

Lp(a) in Hypothyroidism
F.S.Geethanjali* , M.S. Seashadri** and A.S. Kanagasabapathy***
Departments of Clinical Biochemistry*, Endocrinology ** and Former Professor in Clinical
Biochemistry*** , Christian Medical College, Vellore.
Objective: Thyroid disorders are known to
influence the lipoprotein metabolism. In
hypothyroidism the plasma concentrations of the
LDL fraction is elevated. Since Lp(a) and LDL
share the apoB100 in common, this study is to
evaluate the Lp(a) levels in Hypothyroid patients
and its risk for artherogenesis in them.
Methods: Eighty four primary hypothyroid
patients attending the Endocrinology Clinic and
sixty four euthyroid subjects were included in the
study. Serum Lipid profile, thyroid function tests
and plasma Lp(a) levels were performed.
Results: The thyroid profile showed typical
euthyroid and hypothyroid patterns. The mean age
255
for both the groups was comparable. Total
cholesterol, triglycerides and LDL cholesterol
were significantly elevated in the hypothyroid
patients. HDL was marginally increased but not
statistically significant. The plasma Lp(a) levels
were markedly increased in hypothyroid compared
to the euthyroid.
Conclusion: The hypothyroid induced changes in
lipoprotein metabolism could directly or indirectly
promote atherogenesis. The elevated cholesterol
and LDLc fraction may be due to the reduced
activity of the LDL receptor. There are suggestions
that the Lp(a) concentrations depend on the amount
of apo(a) available for binding to apoB100 and
not vise versa. The thyroid hormones which are
known to affect the biosynthesis at the
transcriptional and / or translational level of the
apoprotein could reasonably exert an effect on
apo(a) synthesis. But it is unclear whether the
increased synthesis or the decreased catabolism
could be the cause of Lp(a) elevation in
hypothyroid patients.

Role of Myelin Oligodendrocyte Glycoprotein and Galactocerebroside Antibodies
on Phosphorylation and Degradation of Myelin Basic Protein In Isolated Myelin:
Implications in Multiple Sclerosis.

Clayton, Victoria, Australia. email:[email protected]
Background: In Multiple Sclerosis (MS), both
neuronal and myelin damage is the cause of the
ensuing neurodegeneration leading to
neurological deficit. This process results from an
autoimmune attack on myelin in combination with
genetic susceptibility and the involvement of an
unknown environmental factor. Although the
pathogenic role of immunoglobulins (Igs) directed
to myelin antigens in inducing myelin/
oligodendrocyte damage have been elucidated,
how the pathogenic Igs induce biochemical
breakdown of myelin is poorly understood. Role
of MS Igs as well as monoclonal antibodies
(mAbs) directed to myelin oligodendrocyte
glycoprotein (MOG) and Galactocerebroside
(GalC), in inducing significant myelin basic
protein (MBP) degradation mediated by neutral
proteases in myelin had been shown. MBP plays
a pivotal role in the structural organization of
myelin. Thus breakdown of MBP could lead to
myelinolysis.
256
Methods: In order to elucidate the mechanism by
which specific anti-MOG and anti-GalC antibodies
induce MBP degradation, we have investigated the
possible ways by which MBP is made vulnerable
to proteolysis as well as the relationship between
Gal C and MOG.
Results: In this report, we demonstrate that
antibodies to GalC and MOG induced
phosphorylation of MBP prior to its degradation
in isolated human myelin. Neither such a
phosphorylation nor a degradation of MBP could
be observed using antibodies directed against MBP
or a plant glycoprotein (control Igs).
Conclusion: We here suggest that phosphorylation
of MBP may result in the exposure of MBP to
proteolysis as a result of poor MBP-lipid
interaction leading to myelinolysis. It is likely that
these demyelinating antibodies may mimic the
naturally occurring ligands to MOG/GalC and we
propose a possible interaction between MOG and
GalC in inducing myelin damage thus exploiting

AI in patients with complications was also
significantly higher than those without

values AI can be used as a better indicator for
complications than using the ratio of CHOL/HDL-C.
Conclusion: An imbalance between the LDL and
HDL particles, where in, increase in the number
of small and dense LDL and decreased HDL levels
leads to atherogenic dyslipidemia and increased
incidence of plaque. Both lipid indices indicated

diagnostic marker of increased cardiovascular risk
in patients with Type II DM, and a guide for

Type-2 Diabetes.
Dr. Itishri Jena and Prof. Prakash Ch. Mohapatra
S.C.B. Medical College and Hospital, Cuttack, Orissa, India. Email id: [email protected]
Objective: Diabetes Mellitus is the leading
endocrine disorder of global interest that leads to
thromboembolic phenomena in future. The
pathogenesis of diabetic vascular disease is not
clearly known. Haemorrheological as well as
hypercoagulable states have been suggested to
cause this complication. In order to asses the status
of coagulation, we investigated prothrombin time
(PT) and activated partial thromboplastin time
(APTT) in diabetic patients and their relation with
blood glucose, Glycated haemoglobin (HbA1c)
and insulin resistance.
Methods: A study was undertaken to evaluate
these parameters in 60 diabetics and 30 normal
controls attending the out and in-patient
department of S.C.B. Medical College and
Hospital, Cuttack, during the period from July
2008 to March 2009. Both PT and APTT were
measured by an automated blood coagulation
analyzer, CA-50, manufactured by Sysmex.
Results: The average age of cases was 51.55 years
with average duration of disease 5.8 years. Both
PT and APTT were observed to be shorter in
diabetics than in controls; though within normal
range. The fall is more marked in diabetics with
complications (p<0.05). Both PT and APTT
revealed association with hyperglycemia and
insulin resistance.
Conclusion: Our study revealed an association
between shortened PT and APTT with
hyperglycemia which may lead to thromboembolic
complications in future. Identification of such
factors may allow identifying that subset of
diabetic patients at risk of thromboembolic
complications and special preventive measures
may be provided to them.

Objective: Insulin resistant patients are at an
increased risk of developing metabolic syndrome,
a major cause of heart disease and dyslipidemia.
Metabolic syndrome is a cluster of metabolic risk
factors that come together in a single individual.
Hence in the present study the prevalence of
metabolic syndrome among Type 2 diabetes
mellitus by WHO criteria has been carried out.
The risk factors are compared between patients
with Type 2 diabetes mellitus with and without
metabolic syndrome.
Methods: 87 age matched Type 2 diabetic patients
attending a diabetic clinic were included in this
study. The biochemical parameters like FBS,
PPBS, lipid profile were estimated using
diagnostic kits. Blood pressure was measured and
BMI was calculated. The prevalence of metabolic
syndrome was carried out by classifying the
parameters based on WHO criteria.
Results: The prevalence of metabolic syndrome
as per WHO criteria was 33% in Type 2 diabetic
patients. A significant increase was seen in TGL,
VLDL, TGL/HDL ratio, BP, BMI and a decrease
was observed in HDL of Type 2 diabetic patients
with metabolic syndrome when compared with the
Type 2 diabetic patients without metabolic
syndrome.
Conclusion: The significant increase in TGL,
TGL/HDL ratio, BP, BMI of diabetic patients with
metabolic syndrome when compared to the Type2
diabetic patients without metabolic syndrome
predicts that patients with Type 2 diabetes mellitus
with metabolic syndrome are at a higher risk level
for CHD.

Department of Biochemistry,Penang International Dental College, Vinayaka Missions University,
Salem. [email protected]
Objective: Hydrogen cyanide is one of the
chemicals responsible for tissue hypoxia. Chronic
exposure to HCN may cause neurological,
respiratory, cardiovascular and thyroid defects.
Onset of symptoms depends on dose and duration
of exposure. Large scale of cassava processing
could be disastrous due to discharge of
hydrocyanic acid into the air. Hence the present
study is taken to assess the thyroid dysfunction
leading to impairment in energy metabolism.
Methods: 25 cassava workers in Salem and age
matched controls were taken up for this study.
Their clinical history was obtained and the
following parameters are estimated using a fasting
blood sample. Blood sugar, lipid profile, serum
total protein, urea, creatinine and T3, T4, TSH are
estimated using diagnostic kits.
Results: Our study reveals a significant increase
in triglycerides and TGL/HDL ratio which is a risk
factor for cardiovascular disease. This triglyceride
is predominantly endogenous and may be
synthesized from sugars that cannot enter energy
producing pathways. The results of T3, T4 and TSH
will be discussed.

Objective: The fact that women are most
vulnerable to obesity and our observation that
considerable number of females residing in
Kasturba medical college (KMC) hostels are
gaining weight made us take up this study.
Although obesity is a prevalent problem in all
parts of world, very few data are available
regarding obesity among young Indian women.
This study was conducted to explore the problem
among the female hostel inmates and to identify
different factors contributing to obesity.
Methods: Survey approach was a nonexperimental study in which we investigated 266
female hostel inmates of age group 17-27. Their
260
biometrical characters such as height, weight, body
mass index (BMI), waist-hip ratio (WHR), waist
circumference (WC) and food habits were studied.
Data analysis was done using SPSS (version 14).
Results: According to waist-hip ratio, 227(85.3%)
out of 266 females were found to be overweight
where as only 32(12%) females were found to be
overweight when BMI was considered.
Conclusion: Significant correlation was observed
between the different biometric characters. Since
WHR is a slightly stronger predictor of CVD risk
than WC or BMI, the female inmates of KMC
Hostels, Manipal are susceptible to disorders
associated with obesity.

In present study we measured atherogenic index
of plasma (AIP) & its relationship with fasting
blood glucose in diabetes mellitus patients.
Methods: Fasting glucose, fasting lipid profile and
AIP were estimated in 50 diabetes mellitus patients
and 50 healthy controls. Lipid profile and fasting
blood glucose was analyzed by auto analyzer. AIP
was calculated using formula log [TG/HDL-C].
Results: There was significant increase in Fasting

Conclusion: According to previous studies,
elevated AIP levels increases the risk for
development of atherosclerosis. In our study we
observed elevated AIP in diabetic patients which
predisposes them for development of
atherosclerosis. The positive correlation between
fasting blood glucose and AIP indicates poorly

Objective: To evaluate oxidant stress status in
diabetes mellitus and its association with
proteolytic system in erythrocytes. The parameters
assessed are erythrocyte malondialdehyde (MDA)
levels and proteolytic enzyme activity in both
diabetic individuals and controls.
Methods: 51 non diabetic patients (mean
age=54.47); 53 diabetic patients (mean age=52.92)
were included in the study. The diabetic status was
assessed by estimating the fasting blood sugar
(FBS) using glucose oxidase method. Oxidant
stress was measured by estimating erythrocyte
MDA in terms of thiobarbituric acid reacting
substance (TBARS). Proteolytic activity by the
amount of amino group released by the erythrocyte
lysate of the diabetic individual using
phenylhydrazine treated hemoglobin as substrate.
Results: Erythrocyte MDA was higher in diabetics
(4.7±1.7nmoles/gHb) than the controls
264
(3.3±2.2nmoles/gHb) [p=0.001]. Erythrocyte
proteolytic activity was higher in cases (167.2±648
nmoles/gHb) than the controls (27.9±31.7 nmoles/
gHb). FBS did not correlate with the erythrocyte
MDA in diabetic patients and erythrocyte
proteolytic activity. No correlation between
erythrocyte MDA and erythrocyte proteolytic
activity in cases.
Conclusion: The erythrocyte lipid peroxidation
was increased in diabetic patients. The proteolytic
activity in the erythrocyte lysates of diabetic
patients was significantly increased. There was no
correlation of proteolytic activity and the TBARS
in erythrocytes of diabetic subjects. Diabetes is
associated with a significant increase in TBARS
which is an index of oxidant stress. Proteolytic
enzymes degrade many oxidatively altered
proteins preventing the accumulation of altered and
damaged proteins in the cell.

Body Composition ?
Victoria Job, Venkataramana Raju* and George T John*
Clinical Biochemistry, * Nephrology, Christian medical college, Vellore
Background: Weight gain is common after renal
transplantation, influenced by improved appetite
and a reversal of the uremic state. An increased
centripetal obesity and muscle atrophy accompany
the long term glucocorticoid requirements. Such
changes in body composition are associated with
an increased risk of cardiovascular complications,
which is a major cause of morbidity and mortality

Objective: Aim of this study was to investigate
the inhibition of 5á-reductase type I enzyme using
extracts from Indian medicinal plants. This
enzyme converts testosterone into metabolites
such
as
dihydroxytestosterone
and
androstenedione. Type I 5á-reductase has been
implicated in skin disorders such as acne,
hirsuitism and male pattern baldness and its
inhibition offers a potential treatment for these
disorders.
Methods: Plant extracts selected for this study
were screened and selected based on their ability
to inhibit acne-causing microorganisms. PC3 cell
lines were used as a source of 5á-reductase type I
enzyme and experiments were conducted at pH7

Thyroid Function in Diabetic Subjects
Ranjani.P and Vijaya Srinivasan
Department of Biochemistry, Sri Ramachandra Medical College and Research Institute, Sri
Ramachandra University, Chennai.
Objective: Diabetes mellitus and thyroid disease
are the two common endocrinopathies seen in
adult population. Insulin and thyroid hormone
being intimately involved in cellular metabolism
excess or deficit of either of these hormones could
result in the functional derangements of the other.
Several studies have documented the prevalence
of the thyroid disease in women with prevalence
rates ranging from 4 to 21%and the rate in men
being 2.8 to 16%. However the studies on the
association of thyroid disease and diabetes are
scarce. Failure to recognize the presence of
abnormal thyroid hormone levels in diabetes may
be the primary cause of poor management often
encountered in some treated diabetics. The present
study was therefore undertaken to evaluate the
thyroid function in diabetic subjects.
Methods: The study was undertaken at Sri
Ramachandra Medical College, Chennai. People
in the age group of 30-60 years with diabetes
mellitus were included for this study. The control
group consisted of normal subjects in the age
group of 30-60 years. The blood sample obtained
266
from the patients was processed. The thyroid
hormones T3, T4, TSH and FT4 were analyzed by
using automated analyzer ADVIA Centaur system.
Results: The T3 concentration was lower (p<
0.001) in diabetic patients compared to normal
subjects. A significant negative correlation was
observed between the fasting blood glucose and
T3 levels (r = -0.41) in diabetic patients. The
decreased T3 levels could probably be due to
decreased peripheral conversion of T4 to T3,
increased degradation or clearance of T3 or else
increased T3 metabolism via alternative pathway
other than deiodination. No significant variation
in T4,TSH and FT4 were observed in diabetic
subjects.
Conclusion: The finding of the present study
suggests that alteration of thyroid hormone is a
characteristic feature in diabetic patients. The
detection of abnormal thyroid hormone levels in
the early stage of diabetes mellitus will help the
patients to improve quality of life and reduce the
morbidity rate. Thus evaluation of thyroid profile
is essential in diabetic subjects.

Atypical Findings of Oral Glucose Tolerance Test (OGTT) Curve in Gestational
Diabetes Mellitus (GDM)
Shivaraj Gowda, P B Desai, Vijayetha S Kagwad, Sindhu J Shetty and M B Ilakal.
Department of Biochemistry, J. N. Medical College, Belgaum 590010, Karnataka
Background: Gestational diabetes mellitus is
defined as any glucose intolerance detected during
pregnancy associated with the metabolic risk of
type-2 diabetes mellitus and high risk of maternal
and perinatal morbidity. Early diagnosis is very
important to prevent the complications and OGTT
is the preferred test to detect GDM. The objective
of the study was to analyze the pattern of OGTT
curve and to understand the response of Insulin
to the glucose metabolism.
Methods: A total of 96 pregnant women at high
risk were undertaken for OGTT and test performed
at 24-28 weeks of gestation using 100gms of
glucose. The test results were plotted on a graph
and interpreted using Carpenter and Coustan
criteria.
Results: 15 women were diagnosed as GDM and
5 out of them show atypical patterns in OGTT
curve. Similar such patterns were also seen in 5
normal subjects.
Conclusion: The shape of the OGTT curve is
related to glucose metabolism, â-cell function and
insulin sensitivity. Pregnancy is a state of
physiologic insulin resistance. Insulin secretion
pattern is disturbed in patients with insulin
resistance. The atypical findings of OGTT will be
discussed in the scientific presentation

Medicine, MGM Medical College, Kamothe, Navi-Mumbai, Pin-410 209 [email protected]
Objective: A distinguishable feature of type-2
diabetes besides hyperglycemia and deranged lipid
profile is an impaired insulin secretion, peripheral
insulin resistance, obesity and biological events
due to oxidative stress has become major health
concern worldwide.
Methods: The study was designed to find out
correlation between lipid peroxidation, enzymatic
antioxidant and lipid profile, to rule out oxidative
stress in type-2 diabetes mellitus. Patients with
type-2 diabetes were diagnosed on the basis of
WHO criteria. The degree of lipid peroxidation
was measured in terms of malondialdehyde
(MDA); enzymatic antioxidant viz. superoxide
dismutase (SOD) along with lipid profile to assess
the status of oxidative stress in type-2 diabetic
patients in comparison to the normal control.
Results: There was significant increase in the
product of lipid peroxidation and lipid profile
except HDL cholesterol and superoxide dismutase,
which was found, decreased in comparison to the
normal control. From present study, it is clearly
evident that type-2 diabetic patients were more
prone to oxidative stress.
Conclusion: It is concluded that controlling of
hyperglycemia will prevent alteration in lipid
metabolism and degree of oxidative stress that
definitely plays an important role in prognosis and
prevents secondary complications in type-2
diabetes mellitus.

Assay of CRP and HbA1C in Smokers and Nonsmokers with Type 2 Diabetes Mellitus
in a Segment of Indian Urban Population
Rajyalakshmi Amancherla and Pradeep Naik
Objective: Elevated high-sensitivity C-reactive
protein (hsCRP) levels have been shown to be
associated with type 2 diabetes mellitus (T2DM).
The aim of the study was to assess the association
of hsCRP with type 2 diabetes and to determine
its correlates with HbA1C in a segment of urban
population from the twin cities of Hyderabad.
268
Methods: HbA1C and hsCRP were measured in
545 urban subjects by cation exchange
chromatography and ELISA respectively.
Results: Our results showed that a significant
increases in hsCRP levels were observed with a
mean (± SD) values of 1.65 ± 0.02 mg/L in normal
smokers when compared to normal non smokers
who had mean (± SD) of 0.96 ± 0.02 mg/L.
HbA1C levels were also significantly increased
in smokers who showed 6.5 %± 0.1 whereas non
smokers showed 5.5 % ± 0.1 value. In the case of
diabetes group smokers showed significantly
higher values of hs CRP and HbA1c than their
non smoker counterparts. The diabetic smokers
showed 3.3 ± 0.2 mg/L hs CRP whereas the
diabetic non smokers showed 2.1 ± 0.3 mg/L hs
CRP in the serum. Similarly the diabetic smokers
showed 9.2 % + 0.2 HbA1c whereas the diabetic
non smokers showed 7.99 % + 0.3 HbA1c in the
blood. All the subjects were free from
hemoglobinopathies and any other blood disorders.
We demonstrate the association of low-grade
systemic inflammation, as indicated by elevated
hsCRP levels, with T2DM in Indian population.
Smoking seems to play a major role in the increase
of systemic inflammation irrespective of blood
glucose levels.

Association of ApoA5 1131 T>C Polymorphism with Triglyceride Levels in Indians
R.Lakshmy, HPS Sachdev, Meenakshi Sharma, SK Bhargava, GR Chandak and KS Reddy
Cardiac Biochemistry, AIIMS, New Delhi
Objective: ApoA5 gene occurs near the ApoA1/
C3/A4 cluster on human chromosome 11q23.
Knocking out ApoA5 gene in mice increases
triglycerides by a factor of four. A polymorphism
in the non coding region located 5’ to the ApoA5
gene at nucleotide 1131 has been shown to be
associated with high triglyceride levels in humans.
The polymorphism results from T to C substitution
at 1131. AopoA5 -1131C has been reported in 78% of Caucasians, 33% of Chinese and 35% of
Japanese population. Since Indians have a higher
prevalence of metabolic syndrome characterized
by high triglyceride and low HDL, we looked at
the relative contribution of ApoA5 T1131C
polymorphism on triglyceride levels.
Methods: The study was conducted in 1300
adults residing in Delhi. Polymorphism at ApoA5
T1131C was assessed by ARMS PCR. The lipid
levels as well as LDL and HDL sub fractions were
determined in all the subjects.
Results: The associations of ApoA5 1131
genotype with lipid variables were computed. The
TT genotype was present in 66% of the population
studied, 30.5% had the TC genotype and 3.5% had
CC genotype with the minor allele (C) frequency
of 18.6%. This is higher than the 7-8% frequency
of minor allele of ApoA5 (1131) reported in
Caucasians. Subjects with CC had significantly
higher fasting and post prandial triglyceride levels
as compared to the subjects with TT genotype
(p<0.001). 25% of the subjects with TT genotype
had triglyceride >150, 32% of the subjects with
CT genotype had hypertriglyceridemia where as
45% of subjects with CC genotype had high
triglycerides. None of the other variables studied
showed any association with ApoA5 1131
polymorphism.
Conclusion: In conclusion ApoA5 variation may
be an important determinant of triglyceride levels
in Indians.

Vinayak S Bhat 1, Reshma Kumarchandra 1, and Vijay S. Bhat 2
1. Kasturba Medical College, Mangalore, 2. Manipal Hospital Bangalore
Background: Metabolic syndrome is a
combination of medical disorders that increase the
risk of developing cardiovascular disease and
diabetes. It is a multifactorial disorder
encompassing abdominal obesity, altered glucose
and lipid metabolism, insulin resistance,
hypoadiponectinemia, elevated blood pressure and
high level of CRP. For the present study, controls
were on prescribed diet and exercise and subjects
selected had most of the characteristics of
metabolic syndrome.
Objective: To estimate the parameters such as
Adiponectin, CRP and HOMA score, FBG, lipid
profile, Homocysteine, HbA1c & to make a
correlative study of multivariate factors using
Kruskal–Wallis one-way analysis of variance and
analysis of variance (ANOVA) involved in this
abnormal clinical condition and also to check
whether diet and exercise have any effect on
reducing the abnormal level of the different
parameters involved in this disorder.
Methods: Two categories of subjects were taken
for the study, first category consisting of controls
(10 members) and second category consisting of
tests (61 members). Fasting insulin was estimated
by electrochemiluminiscence method. HS-CRP by
Immunonephelometric method, plasma
Adiponectin was estimated by ELISA. FBG was
by Hexokinase method. Cholesterol was by
CHOD-POD method & Triglyceride by GPO-PAP
method. Statistical analysis was done by using
Kruskal – Wallis one way analysis of variance and
by ANOVA.
Results: Inverse relationship was observed
between Adiponectin level and HOMA score, as
well as with HS-CRP. A direct relationship between
CRP & Homocysteine, HOMA score &HbA1c,
history & Homocysteine, blood pressure &
Homocysteine was observed. These values were
statistically significant (p-value < 0.0001). Post
exercise for 2 months, there was an increase in
level of adiponectin in all the controls which also
271
indirectly brought in corrections in rest of the risk
factors. Conclusion: After all the investigation and
data analysis in this work on metabolic syndrome,
we observed altered levels of various parameters
like, CRP, adiponectin, homocystiene, lipid
profile, HOMA score(insulin resistance), blood
pressure, fasting blood glucose etc. When we
compared these parameters with the controls
parameters we observed a significant difference
in the values of parameters. So based on the results
of this study, we come to a conclusion that proper
diet and regular exercise has an effect on bringing
down the different parameters to normal level and
the persons who are on the borderline and prone
to develop the metabolic syndrome can reverse it
back with proper diet and exercise.

Department of Biochemistry and Physiology, Educare Institute of Dental Sciences,Malapuram,
Kerala -675506, India.
Objective: Metabolic Syndrome is one of the
commonest risk factors for Cardiovascular
272
diseases. The major characteristics of metabolic
syndrome include insulin resistance, abdominal
obesity, elevated blood pressure and lipid
abnormalities.The present study was aimed at
establishing the link between Metabolic syndrome
and it’s role as an atherogenic risk factor in an
Indian perspective. It is now established that this
syndrome predicts the development of type 2
diabetes mellitus and cardiovascular
disease.[1]The prevalence of the metabolic
syndrome depends on age, ethnic background, and
gender. It rises linearly from 20 to 50 years and
plateaus thereafter. Looking at various studies
around the world, which included population
samples, aged from 20 to 25 and upwards, the
prevalence varies from 8% (India) to 24% (United
States) in men and from 7% (France) to 46%
(India) in women.1-3
fibrinogen, High sensitivity C reactive protein( hsCRP) and Insulin were analyzed in both Case
Group and Control Group
Results: The two sample t statistical analysis of
the results of the data from 225 individuals showed
a statistically significant increase in all parameters
in the Case Group compared to the Control Group
(p<0.001).
Conclusion: This establishes a strong link between
Metabolic Syndrome and atherogenic risk factors
substantiating similar observations elsewhere.

Department of Biochemistry and Physiology, Educare Institute of Dental Sciences,Malapuram,
Kerala -675506, India.
Objective: Sub clinical hypothyroidism (SH),
defined as the clinical status of mildly elevated
serum TSH levels, is a far more common disorder
than overt hypothyroidism with a higher
prevalence among women and older subjects.
Certain studies have indicated that sub clinical
hypothyroidism has been associated with
increased risk of CAD, especially in women with
antibodies to thyroid peroxidase. Moreover, SH
impairs ventricular function as well as
cardiovascular and respiratory adaptation to effort
and, decreases heart rate variability impairs flowmediated vasodilatation, which is a marker of
endothelial function 1-3. The present study is an
effort to investigate the CVD risk profile in women
having autoimmune sub clinical hypothyroidism
with elevated Anti Thyroid Peroxidase
Antibodies.(Anti TPO Ab.)
273
Methods: The study was carried out in blood
samples from 150 women in the age group of 35
to 50 who are suspected to have hypothyroidism
were included in the Case Group.80 apparently
healthy women in the age group of 35 to 50 with
normal serum TSH levels comprised the Control
Group. Blood / serum TSH, Free T3, Free T4,
Anti TPO Ab, Total Cholesterol, LDL cholesterol,
Triglycerides , Plasma fibrinogen and High
sensitivity C reactive protein
( hs-CRP) were
analyzed in both Case and Control Groups. The
data from the blood investigations were analyzed
statistically using Two Sample‘t’ test.
Results: All the blood / serum parameters which
were analyzed in our study were found to be
increased significantly in the Case Group when
compared to the Control Group (p < 0.001).
Conclusion: Thus the Case Control study in 200
women having sub clinical hypothyroidism with
elevated Anti Thyroid Peroxidase Antibodies
showed that they are at a higher risk for CVD than
their age-matched control counter parts.

Warangal-506007. Andhrapradesh.
Background: Rheumatoid arthritis is a common
debilitating, crippling disease with unknown
etiology associated with chronic inflammation and
bone resorption. Increased oxidative stress
contributes to the etiopathogenesis of R.A.
Objectives: Present study aims to determine the
oxidative injury by estimating the levels of
prooxidant Malondialdehyde and to study the role
of oxygen derived free radicals in R.A by assessing
the influence of disease process on serum calcium,
phosphorus, ALP levels in a view to study the
beneficial influence of adding free radical
scavengers to the existing therapeutic regimen.
Methods: The study was conducted on 50
clinically diagnosed cases of R.A who fulfill the
ARA criteria, compared with age & sex matched
controls with out systemic diseases like DM, HTN,
RF. Estimation of Malondialdehyde was done by
TBA assay, Calcium by O-CPC method,
Phosphorus by Fiske and Subbarao method, ALP
by King & Kind. Statistical analysis was done by
using student “t” test and p-value <0.05 were
considered as statistically significant.
Results: The results that were found are
statistically significant increase in serum MDA
levels (p<0.001), decrease in serum Calcium
(p<0.001), increase in serum Phosphorus (p<0.01),
decreased Ca,P ratio (p<0.001) and with no
statistically significant change in serum ALP levels
(p>0.05) in R.A patients as compared with control
group.
Conclusion: The observations in the present study
shows that oxidative stress plays an important role
in the etiopathogenesis of R.A and addition of free
radical scavengers as supplements may prove to
be beneficial. There is an altered Calcium and
Phosphorus metabolism and Ca,P ratio in R.A and
increase in MDA levels, an important marker.

Objective: Diabetes mellitus is a commonest
endocrine disorder which represents the serious
risk factor for the development of cardio vascular
diseases. Oxidative stress is a pathophysiological
state in which there is excess of Reactive Oxygen
Species. In diabetes mellitus oxidative stress
results from hyperglycemia. Oxidative stress alters
the plasma lipoprotein profile, the coagulative
parameters, the endothelium and the cell
membrane. Hence the present study was focused
to understand the total antioxidant level by Ferric
Reducing Antioxidant Antioxidant Power assay.
Methods: To conduct this study, blood samples
were collected from the thirty patients from the

intervention was a set of standardised physical
exercises (15 minutes/day) and walking (20-25
Results: Total antioxidant levels are increased
significantly (p<0.025) after three months of
exercise and decreased significantly (p<0.048)
after three months of yoga. There is a significant
decrease in TA in post yoga group (p<0.001) as
compared to post exercise group (control).
Conclusion: There is a significant decrease in total
antioxidant levels after yoga intervention probably
due to increased consumption of TA to prevent
the oxidative stress when compared to exercise

Objective: Thyroid hormone plays important role
in normal hepatic function. Hypothyroidism may
perturb normal metabolic function of liver. Low
activity of thyroid hormones may also be
associated with oxidative stress causing decrease
antioxidant capacity.
Methods: Prospective study has been done to
assess liver function and total antioxidant capacity
in 100 hypothyroid patients compared to healthy
controls. Following parameters has been measured
at the time of detection & then after 6 weeks. TSH:
Competitive Solid Phase Enzyme Immunoassay
Alkaline Phosphatase: p-nitrophenyl phosphate
Gamma Glutamyl Transferase: End point pnitroaniline method Total Antioxidant Capacity:
Korvacevic method.
Results: TSH level of hypothyroid patients were
found to be increased significantly at the time of
detection when compared to controls (P<0.001),
but values were found to be reduced after 6 weeks
of therapy. Activity of both liver enzymes ALP,
GGT were found to be reduced in hypothyroid
patients at the time of detection, but after 6weeks
of therapy values of ALP & GGT were improved.
(P<0.05). Total Antioxidant Capacity were also
reduced in hypothyroid patients, that was found
to be improved after six weeks of therapy
(P<0.001).
Conclusion: From above results it may be
concluded that hypothyroidism modulate normal
liver function, thus interfering with the liver
enzyme production or probably its activity.
Increased TSH may stimulate excess oxidative
stress, thus creating load on Antioxidant Capacity.

*Senior Resident, Department of Biochemistry, NEIGRIHMS, Shillong-18; E [email protected],
Objective: The present study was undertaken to evaluate the metabolic correlation between
279
preeclampsia and oxidative stress.
Methods: We selected 95 no of subjects for the
study out of which normal nonpregnant control
group had 25 subjects, normal pregnant control
group had 40 subjects & preeclampsia group
constituted of 30 subjects. The investigations
included are serum lipid profile consisting of serum
total cholesterol, serum triglycerides, VLDL, LDL
and HDL, serum vitamin E as á- tocopherol and
malondialdehyde.
Results: There is significant increase in serum
triglyceride, serum cholesterol along with LDL and
VLDL (p<0.0001) in pregnancy over nonpregnant
controls and preeclampsia over pregnant control
(p<0.0001). It is observed that in normal controls
without pregnancy there is no relationship between
serum vitamin E and serum lipid peroxidation as
represented by whole blood MDA
(malondialdehyde) with a correlation coefficient
of 0.13 only. In contrast to this, under the condition
of normal pregnancy and preeclampsia the
correlation between these two parameters
increased with coefficients of correlation (r = - 0.9)
with a negative trend indicating a definite and
significant degree of inverse relationship between
two.
Conclusion: It is finally proposed that adequate
vitamin E supplementation during pregnancy with
proportionate increase in preeclampsia may reduce
the consequences of peroxidation induced
complications during pregnancy.

Antioxidant Status in Goats During Pregnancy
Cynthia Jose* and K.K. Jayavardhanan**
* MVSc Scholar, ** Associate Professor, Department of Veterinary Biochemistry, College of Veterinary
and Animal Sciences, Mannuthy, Thrissur- Pin 680651 [email protected]
Objective: Production of free radicals is a
physiological phenomenon which occurs
continuously in the body during metabolism and
body usually has sufficient antioxidant reserves
to cope with its production. However, when free
radical generation exceeds the body’s anti-oxidant
production capacity, oxidative stress develops.
The aim of the present study was to evaluate under
field condition the oxidative status in healthy goats
during pregnancy on the basis of 3 parameters:
plasma levels of malondialdehyde (MDA),
reduced glutathione (GSH) and glutathione
peroxidase (GSH-px). In order to evaluate
metabolic homeostasis, common metabolic
parameters (glucose, total protein, albumin,
cholesterol, urea and creatinine) were determined
as well.
Methods: The study was carried out using 15
healthy female cross bred goats maintained at
280
Kerala Agricultural University Goat Farm,
Mannuthy. Blood samples were collected 4 times:
before pregnancy, at 2 nd and 4 th months of
pregnancy and one week before kidding. The
values obtained during pregnancy were compared
with those obtained in the same animals before
pregnancy.
Results: The study showed that the lipid
peroxidation was increased in the pregnancy
period as revealed by an increase in MDA level.
Significant higher MDA level was observed in the
4th month of pregnancy. This suggested that after
the middle gestation period, the body presents high
levels of free radicals which cause lipid
peroxidation. The activity of anti-oxidant enzyme,
GSH-px and the level of GSH were also found
increased in this period, providing protection to
the fetus against the negative influence of free
radicals. The serum glucose concentration was
significantly lower in the 4th month of pregnancy,
indicating low energy balance in this period. The
cholesterol and creatinine concentrations were
higher in pregnant goats with a peak level in the
late pregnancy period.
Conclusion: The data suggest that the
antioxidative/prooxidative status is associated with
the metabolic adaptations to low energy balance,
which occur during pregnancy.

Objectives: - Oxidative stress and changes in
antioxidant status have been implicated in the
pathogenesis of malaria. Bikaner district, being a
part of Thar desert due to extremes of temperature
has always been regarded as hypoendemic region
for malaria but in recent years prevalence of
Malaria has increased in this region due to changes
in Ecosystem contributed by increased rainfall and
Canal Irrigation. So this study was conducted in
patients with Plasmodium falciparum and
Plasmodium vivax malaria to evaluate status of
lipid peroxidation and effect on vitamin E and C
level.
Methods: - In study we included 100patients out
of which 50were suffering from Plasmodium vivex
Malaria and other 50with Plasmodium falciparum
Malaria. Plasma Thiobarbituric acid reactive
substances(TBARS) were measured using Buege
& Aust’s Method(1978) to assess the degree of
lipid peroxidation and antioxidant status was
measured by estimating the level of Vit E&C
using Baker & Frank’s Method(1976) using
Bipyridyl reagent and Roe & Kuethe’s Method
using 2.4DNPH respectively. Results were
compared with age and sex matched control
subjects(n=50).
Results: Our study demonstrates that level of
oxidative stress was significantly increased
(P<.001) while antioxidant vitamins E&C were
significantly decreased (P<.001) in both the groups
of malaria. Plasmodium falciparum (2.82+ 1.06
nmol/ ml) malaria showed significantly increased
(P<.001) level of Malondialdehyde when
compared to Plasmodium vivax malaria (1.72+
0.70nmol/ml). Maximum decline in Vit C level
(p<.001) were observed in plasmodium vivax
malaria while maximum decline in Vit E level
(p<.001) were observed in Plasmodium falciparum
malaria. Therefore it has been hypothesized that
the oxidative stress induced by malaria can be,
combated by augmentation of Vit E&C.

Objective: Diabetes Mellitus has reached
epidemic proportions with an alarming rise in the
Asian countries including India. This particular
study has been taken up to compare the serum
NO level in patients with diabetes and healthy
controls and to establish correlation between
serum nitric oxide level and diabetes mellitus in
Sikkim.
Methods: Lipid Profile and serum nitrite were
assayed in 52 subjects, 26 of which were
diagnosed cases of type II Diabetes Mellitus
undergoing treatment in SMIMS and 26 were
healthy volunteers. The statistical analysis was
done using SPSS 17 and the comparison between
cases and control was calculated by Student’s t –test.
282
Results: Most of the patients were above 40 years
of age. Mean serum nitrite was lower in diabetics
in comparison to non-diabetics but the difference
was insignificant (p=0.141). Triacylglyerol, LDL
were markedly raised in Diabetics but statistically
insignificant (p=0.08), (p=0.55). HDL was
significantly lower in Diabetics in comparison to
non diabetics (p=0.001). Total Cholesterol was
markedly lower in diabetics but this difference was
statistically insignificant.
Conclusion: The pattern of findings in our studies
is consistent with the findings elsewhere but not
statistically significant. This could be due to the
duration of diabetes and the role of drugs, dietary
and lifestyle modification prior to the study.

Objective: We evaluated, if cord blood of pregnant
women with oxygen radical disease had different
total enzymatic antioxidant status than those
without preeclampsia (PE).
Methods: Blood from 23 normotensive (control)
and 23 preeclamptic mothers was tested for
Malondialdehyde (MDA); and antioxidant
enzymes, Superoxide dismutase (SOD);
Glutathione Peroxidase (GPx) and Catalase
activity and results were compared for oxidative
and anti-oxidative system in maternal and cord
blood of pair-matched mother and neonate.
Results: MDA in preeclamptic maternal plasma
was significantly high (p < 0.001) as compared to
control. Interestingly, its content in preeclamptic
cord blood was significantly low (p < 0.001)
compared to their pair-matched maternal blood.
SOD activity was 8.7% higher in cord as compared
to pair-matched normotensive maternal blood
which was significant (p=0.01) whereas in
preeclamptic cord the level decreased significantly
(p=0.011) in comparison to pair-matched
preeclamptic maternal. GPx was 16.4% higher in
normotensive cord compared to maternal blood
and 7% low in preeclamptic cord compared to pairmatched maternal blood. The increase was
significant (P=0.011) in normotensive cord
whereas in preeclamptic cord the decrease was
insignificant (p=0.06). Catalase activity showed
20.97% elevation in normotensive and 16.12%
increase in the preeclamptic cord blood compared
to their pair-matched maternal blood. This was
significant with p=0.01 and p=0.017 in control and
preeclamptic group respectively.
Conclusion: we found that the oxidative stress is
low in the blood of neonates born to preeclamptic
mothers. Further studies are needed to explore
strategies so that the normal levels of antioxidant
are maintained to combat preeclampsia in high risk

Effect of Vitamin E Supplement on Blood Anti-oxidant Status in Cigarette Smokers.
Juhi Aggarwal and Sadhana Sharma
Santosh Medical College and Hospital, Santosh University, Ghaziabad-201009, India
Background: Coronary Heart Disease (CHD) is
a major cause of mortality worldwide and smokers
are at high risk of developing CHD. Reactive free
radicals are associated with the formation of
atheromatous plaques. Cigarette smoke contains
free radicals which initiate and propagate the
process of lipid peroxidation.Present study aims
to assess indices of free radical mediated
peroxidation in smokers and non smokers along
with the effect of vitamin E supplementation.
Methods: Two experiments were designed for the
study comprising age group of 30-45 years. Exp.1
has 10 male smokers and 10 non smokers. Plasma
and erythrocyte antioxidants and antioxidant
enzyme status were measured. Exp. 2 included 20
male smokers and 20 non smokers and each given
a placebo followed by vitamin E (1000 mg αtocopherol acetate) for 14 days. Plasma indices of
lipid peroxidation were measured.
Results: For Exp. 1 plasma concentration of
vitamin E were decreased (p < 0.04) in smokers.
Plasma ascorbic acid concentration was 50% lower
in smokers but dehydroascorbic acid concentration
was raised (p < 0.06) in them. Erythrocyte glucose
-6 phosphate dehydrogenase and glutathione
peroxidase levels were significantly lower (p <
0.05 and p < 0.02 respectively) in smokers. For
Exp.2 In smokers, the elevated erythrocyte lipid
peroxidation (p< 0.01) was abolished by vitamin
E supplementation (p < 0.05) and conjugated diene
levels were raised significantly (p < 0.04).
Conclusion: Hence it is evident that free radicals
involved in cigarette smoke contribute to the
pathogenesis of CHD and increased antioxidant
intake inhibits the formation of atheroma.

*Lecturer, **Professor, ***Professor& Head, Department of Biochemistry, MGM Medical College,
Kamothe, Navi-Mumbai, Pin-410 209: [email protected]
Objective: The aim of our study was to determine
the levels of malondialdehyde (MDA), nitric
oxide, zinc and superoxide dismutase (SOD)
activity in seminal plasma and to find out their
correlation with semen parameters.
Methods: The material represents 60 semen
samples, which were divided into two groups:
Group I-Normospermic (n=30), Group IIOligospermic (n=30). Seminal plasma
malondialdehyde, nitric oxide, zinc and SOD were
estimated by spectrophotometric methods. The
study includes determination of selected semen
parameters.
288
Results: Seminal plasma malondialdehyde and
nitric oxide were high in oligospermic than
normospermic. Seminal plasma zinc and SOD
were low in oligospermic than normospermic.
There was a negative correlation between
malondialdehyde and nitric oxide with zinc and
SOD in oligospermic. Seminal plasma
malondialdehyde and nitric oxide showed a
negative correlation with sperm count and sperm
motility. Seminal plasma zinc and SOD showed a
positive correlation with sperm count and sperm
motility in oligospermic group.
Conclusion: The increase in malondialdehyde,
nitric oxide and decrease in zinc and superoxide
dismutase levels in oligospermic may cause
disruption in the membrane integrity of
spermatozoa and may have role in reduction of
sperm DNA integrity. There was a positive
correlation between zinc and SOD with sperm
count and sperm motility, indicating zinc may play
an important role in spermatogenesis and
steriodogenesis. Thus estimation of seminal
malondialdehyde, nitric oxide, zinc, and SOD can
be useful tools for determining sperm fertilization
potential. These parameters could assist in
diagnosis of male infertility and help in treatment
of infertile male.

Departments of 1Biochemistry and 2 Hemato-Oncology Unit, Department of Medicine, C.S.M. Medical
University, Lucknow, India
Background: Chronic myeloid leukemia (CML) is a myeloproliferative disorder with a
289
characteristic genetic rearrangement, the
Philadelphia chromosome. Oxidative stress, a
pervasive condition of increased amount of free
radicals is now recognized to be prominent feature
of various diseases including leukemias and their
progression. The relationship between the levels
of well known oxidative stress markers and
antioxidants status reflect better health indices and
postures. The present study was planned to review
the role of oxidative stress and antioxidant defense
system in patho-biology of CML. Oxidative stress
was assessed in terms of malondialdehyde
(MDA), total lipid hydroperoxide (LOOH) and
protein carbonyl (PC) content whereas antioxidant
status was evaluated in term of reduced
glutathione (GSH) and total thiol (T-SH) and total
antioxidant status (TAS) levels in plasma of CML
patients. Melatonin (MEL) level was measured
in urine.
Methods: The present study included 82 (male:
female; 1.8:1) CML patients and 70 (male: female;
1.5:1) age-sex matched healthy volunteers. Out
of 82 CML patients, 66 were in chronic phase
(CML-CP) and 16 in accelerated phase (CMLAP). The median age of CML patients was 35
years and that of healthy participants 34 years.
Oxidative stress and antioxidant defense system
markers in plasma were evaluated by
spectrophotometric procedures whereas MEL
level was determined in terms of 6sulphatoxymelatonine excreted in urine by ELISA
kit (IBL-Hamburg).
Results: There was a significant increase (p<0.05)
in plasma MDA, LOOH and PC levels in CML
patients as compared to healthy subjects. Our
results also showed that plasma MDA, LOOH and
PC levels were markedly elevated (p<0.05) in both
290
CML-CP and CML-AP as compared to healthy
volunteers. Antioxidant defense system which was
measured in term of reduced GSH, T-SH, TAS and
MEL was found to be significantly decreased
(p<0.05) in CML patients and its phases (CMLCP, CML-AP) as compared to healthy participants.
During the follow-up of total 66 CML-CP patients
for 12 months, 15 patients of CML-CP progressed
to the accelerated phase whereas 51 patients
remain in CML-CP phase. The mean plasma levels
of MDA, LOOH and PC in patients with CMLCP who progressed to CML-AP were found to be
higher than in patients with CML-CP who did not
progress to the accelerated phase. An elevation in
the plasma levels of MDA, LOOH, and PC was
observed in CML-CP patients who progressed to
CML-AP. The antioxidant defense system in
patients with CML-CP who advanced to CML-AP
was found to be decreased than in patients with
CML-CP who did not progress to the accelerated
phase. The antioxidant defense profiles remained
decreased in those CML-CP patients who
progressed to CML-AP.
Conclusion: It could be implicated that plasma
MDA, LOOH and PC levels may reveal the
magnitude of oxidative stress in CML patients
whereas reduced GSH, T-SH, TAS and MEL
explain the antioxidant defense system against
oxidative stress. All these parameters for oxidative
stress and antioxidant defense mechanism may
precisely reflect the proliferative signal
transduction, disease phenotype and its subsequent
disease progression. Plasma MDA, LOOH and PC
may serve as indices for oxidative stress and
disease progression in patients with chronic
myeloid leukemia whereas antioxidant defense
system plays an important role in nullifying the
oxidative stress.

Objective: It is well established that long-term
alcohol consumption leads to liver cirrhosis.
Sufficient work has been done on biochemical
markers of liver damage and antioxidant status of
civilized chronic alcoholics. In the current study
chronic alcoholics from a tribal community called
Koraga are analysed for the same parameters in a
view to assess the extent of liver damage as
compared to healthy controls and civilized
alcoholics.
Methods: Serum and urine samples from Koraga
alcoholics (n=28), civilized alcoholics (n=30) and
healthy controls (n=31) are analysed for liver
function parameters and antioxidant markers.
Liver function parameters are determined by

urine GST in both civilized and Koraga alcoholics
(p<0.01). Serum thiol levels decreased in Koraga
subjects significantly (p<0.01) whereas the
decrease was not significant in civilized subjects.
There was significant increase in urine thiols of
civilized alcoholics (p<0.05) compared to controls,
however, such finding was not observed in Koraga
subjects. On Pearson correlation, serum GST
correlated positively with AST, ALT, total bilirubin
and urine GST (p<0.01), serum thiol levels
correlated negatively with AST and ALT (p<0.05).
Conclusion: Results of our study possibly indicate
that the extent of alcohol induced liver damage in
Koraga subjects is comparatively lower than
civilized alcoholics, even though the alcohol
consumption is found to be higher in them. There
may be some mechanism that is rendering them

Professor & Head of Biochemistry, Rajiv Gandhi Institute of Medical Sciences, Srikakulam, A.P
Objective: India is agriculture based country,
there is more use of organophosphates leading
to various abnormalities, which are largely
caused due to the oxidative stress. The aim
of the study is to assess oxidative stress and
antioxidant status in organophosphorous toxicity
in both acute and chronic exposure cases.
Methods: The study group consists of 40
farmers who have been involved mainly in
spaying activities in the paddy fields for more
than five years from near by villages as chronic
exposure cases and 20 cases of
oganophosphorous poisoning cases as acute
exposure cases. The control group consists of
291
30 volunteers from the same place with same
sex and age and did not exposed to
organophosphates.. Blood samples were
collected and analyzed for Malondialdehyde
(MDA), Superoxide dismutase (SOD) and vitamin
C. The observed values were compared with
control group. Statistical analysis was performed
by analyzing the data using student “t” test and
ANOVA.
Results: In the present study MDA levels were
significantly elevated in Acute Cases (p < 0.001)
and in chronic cases (p <0.001) due to the
inhibition of Acetyl choline esterase and
production of oxidative free radicals. Superoxide
dismutase (SOD) is the first line of defense
against reactive oxygen species. SOD levels
were increased in acute cases (p < 0.001) and
also in chronic cases (p <0.001) due to elevated
antioxidant status.
Conclusion: Vitamin C significantly decreased
in chronic cases than acute cases indicated the
low antioxidant status.

cataract. Disturbance in balance between the
oxidant and antioxidant levels is thought to be one
of the risk factor for the process of
cataractogenesis. The transparency of lens which
depends on the protein structure and optimum
concentration of intracellular calcium is altered
by the process of oxidative stress.
Results: Significant increase in the serum MDA
was observed in patients with diabetic cataract.
Antioxidant activity was significantly reduced in
the serum as well as the lens in these subjects.
However there was no significant change in the
serum and lens calcium levels. Comparison

Objective: Oxidative stress is a biochemical
disequilibrium produced by the excessive
production of free radicals and reactive oxygen
species, which provoke oxidative damage to
biomolecules. Malondialdehyde is the major and
one of the most frequently used indicators of lipid
peroxidation product that is mutagenic and
tumorigenic. The present study was carried out to
determine the oxidative stress in erythrocyte and
plasma of healthy human subjects.
294
Methods: Blood was collected from thirty (30)
healthy individuals (15male and 15 female), age
ranging from 23 to 53 years. Lipid peroxidation
was analysed by the estimation of
malondialdehyde concentration both in erythrocyte
and plasma. Malon-dialdehyde concentration was
determined by estimating thiobarbituric acid
reactive substances (TBARS) by the method of
Buege and Aust.
Results: The mean ages of male and female
healthy controls were 30.93 ± 7.85 years and 26.70
± 6.98 years respectively. TBARS in plasma and
erythrocyte showed highly significant correlation
with respect to body mass index (BMI). In female,
lipid peroxidation was higher in plasma but lower
in erythrocytes. On the other hand, in male lipid
peroxidation was higher in erythrocytes than
compared to plasma.
Conclusion: Our findings suggest that BMI is one
of the governing for the increase of oxidative stress.
The potential relationship between TBARS in plasma
and erythrocytes was observed in control subjects.

Objective: Oxidative stress is involved in the
pathophysiology of diabetes and cardio vascular
complications of metabolic syndrome.
Endothelial dysfunction which is the key feature
of metabolic syndrome and its vascular
complication is intimately linked to insulin
resistance. This relationship is partly due to
oxidative stress. The present study was taken up
to evaluate the oxidant and antioxidant status in
patients with metabolic syndrome as compared
with healthy controls.
Methods: Twenty five patients with metabolic
syndrome diagnosed on the basis of WHO criteria
taken as subjects along with twenty five, age and
sex

dismutase activity (SOD) by continuous
Spectrophotometric rate determination.
Results: A significant increase (p<0.001) in MDA
levels in study group was observed when compared
to the control group, where as FRAP levels were
decreased in study group compared with control
group (p<0.001). SOD activity was decreased but
not statistically significant in study group when
compared with control group.
Conclusion: The findings of the present study
suggest the presence of oxidative stress in patients
with metabolic syndrome which further increase
the cardiovascular risk in these patients. Hence
management should be aimed at treating the
atherogenic factors associated with metabolic
syndrome like dyslipidemia, hypertension etc., and
also correcting the antioxidant status.

Objective: There is growing evidence that
damage to spermatozoa by reactive oxygen
species (ROS) has a key role in male infertility.
The aim of the present study was to assess seminal
plasma Malondialdehyde (MDA), Vitamin C
concentration and Catalase activity. These oxidant
& antioxidants represents the lipid peroxidation
and spermicidal antioxidant activity respectively.
We aimed to correlate the relationship of seminal
parameters, MDA concentration with Catalase
activity and Vitamin C levels in control and study
group.
Methods: Specimens were divided into two
groups: Group I- Normospermia (n=30); Group
II-Oligoasthenozoospermia (n=30). Seminal
MDA concentration was measured by K Satoh’s
method. Seminal Catalase activity was measured
by A K Sinha’s assay. Vitamin C levels are
measured by 2,4-DNPH method.
Results: Seminal parameters, MDA, Vitamin C
levels and Catalase activitiy in both groups were
compared. MDA concentrations in
oligoasthenozoospermic group were significantly
elevated.
Catalase
activities
in
oligoasthenozoospermic groups were significantly
decreased. Vitamin C levels were significantly
lower in oligoasthenozoospermic patients,
comparing to the levels found in normospermic
men. Assessment of ROS, Catalase and Vitamin
C may assist in diagnosis and prognosis of male
infertility.
Conclusion: Treatment strategies must be directed
toward lowering of ROS levels to keep only a small

Objective: Malaria is a major health problem in
developing countries accounting for 2-3 million
deaths per year. Oxidative stress (Lipidperoxidation) plays an important role in
development of malarial anemia. The present
study was done to assess MDA as a marker of
lipid-peroxidation and SOD as an antioxidant in
malaria patients.
Methods: The present study included 50 untreated
malaria cases compared to 25 age and sex matched
healthy control cases. In these patients following
investigation were carried out:1. MDA level was estimated by Buege.et. al.(1978)
method.
2. SOD activity was estimated by Das.et. al.(2000)
method.
3. Hb was estimated by cyan methemoglobin
method.
297
Results: The MDA level was significantly
increased while SOD level and Hb were
significantly decreased in both groups of malaria
patients as compared to control groups. The MDA
level was found to be significantly (P<0.001)
increased while SOD level and Hb were found to
be significantly (P<0.001) decreased in P.Vivax
as compared to control group. The MDA level was
found to be significantly (P<0.001) increased
while SOD level and Hb were found to be
significantly(P<0.001) decreased in P.Falciparum
as compared to control group. The MDA level was
found to be significantly (P<0.05) more increased
in P.Falciparum as compared to P.Vivax while SOD
level was found to be significantly (P<0.001) more
decreased in P.Vivax as compared to P.Falciparum.
The Hb level was found to be significantly(P<0.01)
more decreased in P.Falciparum as compared to
P.Vivax.
Conclusion: We concluded that lipid-peroxidation
is a significant problem in malaria patients. A high
level of MDA and decline level of SOD activity

Anita, Sudha K, Beena V Shetty and Gayatri M Rao
Dept. of Biochemistry, KMC, Mangalore
Objective: It has been suggested that oxidative
stress, defined as a shift in pro-oxidant/oxidant
balance towards oxidants has been associated with
the pathogenesis of many diseases including
carcinogenesis. Reactive oxygen species can
induce carcinogenesis via injury to
macromolecules such as DNA, carbohydrates
and proteins.
Methods: 25 primary gastric carcinoma patients
and 30 healthy control were included in the study.
Advanced oxidation protein products, total protein,
albumin and total antioxidant activity in plasma
were estimated.
Results: Our studies demonstrated a significant
increase in AOPP, A:G ratio(p=0.003,) and total
antioxidant activity(p=0.014).

Conclusion: The findings suggest that gastric
carcinoma is associated with oxygen derived free
radicals accumulation and depletion of total
antioxidant activity has lead to oxidative stress and
advancement of oxidative-antioxidative disorders

Background: Oxygen is an essential component
of living organism but formation of ros (reactive
oxygen species) seems to be common place in
aerobically metabolizing cells. In healthy human
body, ros and anti-oxidans remain in balance but
when balance gets disrupted, ros increases and
leads to occurance of oxidative stress. This
oxidative stress has been implicated in enormous
variety of physiological and pathological
disorders.
Objective: The main objective of the present study
is to estimate malondialdehyde (MDApreoxidant), anti oxidant enzymes SOD
(superoxide dismutase) & CAT (catalase) in
maternal and cord blood of preterm infants
compared to that of normal individuals.

Objective: Pre-eclampsia and eclampsia are
pregnancy complications with serious
consequences for mother and infant. Uncontrolled
lipid peroxidation may play an important role in
the pathophysiology of pre-eclampsia and
eclampsia by causing vascular endothelial cell
dysfunction. Antioxidants serve to control lipid
peroxidation. We tested that antioxidant protective
mechanisms are diminished in women with Preeclampsia and eclampsia.

was significantly increased while enzymatic
antioxidants like superoxide dismutase,
Glutathione perxidase Glutathione reductase and
catalase were reduced significantly as compared
to normal pregnant and non-pregnant controls.
Conclusion: Lipid peroxidation is an important
factor in the pathogenesis of pre-eclampsia and
eclampsia. The decrease in antioxidants is
probably due to compensatory nature responding
to the increased lipid peroxide load in preeclamptic and eclamptic patients and may reflect
the severity of the disease. Early attention,
intensive management and better treatment with
antioxidant vitamins may be essential for
improving the maternal and foetal outcome in PIH

Objective: Chronic alcohol abuse is known to
have a positive correlation with the onset of tissue
injury including liver cirrhosis, pancreatitis,
gastitis, acute respiratory distress syndrome
(ARDS) and an increased risk for the development
of breast cancer. Though the causal relationship
between the alcohol abuse and the disease process
is not clear but was implicated metabolic
activation of ethanol in these tissues might be the
causative of the disease process. Here, using
alcoholic rat animal model and Affymetrix high
density gene chip technology, we report
differential gene regulation in different tissues due
to chronic alcoholism.
Methods: Male and Female Sprague-Dawley rats
were pair-fed with isocaloric Lieber-DeCarli
liquid diets for six weeks. Different tissues of
interest were isolated and subjected for microarray
analyses using Affymetrix gene chip technology.
Results: The data suggests like in liver, there is a
state of oxidative stress in those tissues with organ
injury and is correlated with phase I and II enzymes
that are involved in ethanol metabolism. There
was an increase in the expression of alcohol
dehydrogenase and several cytochrome p450 gene
families in Antrhrum and lung. Several genes
involved in glutathione homeostasis increased
expression levels, including glutathione Stransferases, several inflammatory proteins and
oxidative stress genes are down regulated at the
mRNA level. In the pancreas, it was suggested
that several oxidative stress genes and genes that
are involved in the genesis of inflammation were
differentially regulated.
Conclusion: This produces an imbalance in the
homeostasis of pro and anti-oxidative stress

genesis of diabetes mellitus (DM) (both in type 1
& 2) and as a critical indicator in development of
diabetic complications continues, especially in

Vijayawada, Andhra Pradesh. – 520008. [email protected]
Objective:Kombucha is a home made fermented
tea that has been traditionally consumed in China
for over 2200 years (Since 220 BC), and is now
being used in many other countries. The claimed
306
health benefits of kombucha include in disorders
such as diabetes mellitus, hypertension, cancer,
atherosclerosis, arthritis, constipation, AIDS etc.
The biochemical basis of the health benefits of
kombucha remains largely unknown. The present
study was undertaken to find out the total
antioxidant activity and total content of phenolic
compounds in the kombucha.
Results: Kombucha exhibited good antioxidant
and free radical scavenging activity, besides the
presence of phenolic compounds. Further, the
antioxidant activity and phenolic compounds
concentration were found to increase with
increased fermentation time. It appears that the
claimed health benefits of kombucha consumption
may be partly related to the antioxidants produced
during fermentation.
Methods: Kombucha was prepared by fermenting
freshly made tea after inoculating with a
previously grown culture of kombucha. The
antioxidant activity of kombucha was determined

Objective:The use of medicinal herbs in the
healthcare of humans is centuries old. Oregano
(Origanum Vulgare L.) is widely used medicinal
herb in a treatment of various ailments. The
present study was undertaken to evaluate the
efficacy of oregano by in vivo studies against 1,2dimethylhydrazine(DMH)-induced rat colon
carcinogenesis by estimating circulatory lipid
peroxidation (LPO) and antioxidant status. In
addition, the in vitro antioxidant activity of
oregano was also studied.
Methods: DMH-induced cancer was developed
in Wistar rats. Oregano was orally supplemented
everyday in a dose-dependent manner to different
groups of rats for 15 weeks. Tumour-bearing rats
showed increased LPO in the circulation which
was accompanied by a decrease in
levels of antioxidant enzymes (superoxide
dismutase, catalase etc.), besides reduced
glutathione levels. Oregano supplementation
however, reversed the circulatory LPO and
antioxidant profile in colon cancer bearing rats.
Result:In vitro studies demonstrated that oregano
exhibits good free radical scavenging activity,
besides the presence of phenolic compounds.
Conclusion:The medicinal herb oregano possesses
antioxidant property which was proved by both in
vitro and in vivo studies. This property of oregano
may be involved in the treatment of cancer and
other ailments.

Assistant Professor, Dept of Medical Biochemistry, GVP Biomedical Engineering College for Women,
Visakhapatnam, AP.
Objectives: Oxidative stress is probably involved
in neuronal damage induced by ischemiareperfusion. The present study was designed to
measure the enzymatic and non enzymatic
antioxidant status following acute ischemic stroke
patients with large vessel and small vessel infarcts.
Methods: The study included 72 subjects in which
30 were controls and 42 were acute ischemic
stroke cases. They were diagnosed basing on
clinical manifestations and by CT scan of the brain.
The cases were further divided into 2 groups. The
ischemic stroke patients with large vessel infarcts
(Group-L) and small vessel infarcts (Group-S)
basedCT scan of the brain. Serum enzymatic
antioxidants (superoxide dismutase and
glutathione peroxidase) and the non enzymatic
antioxidants (reduced glutathione, vitamin E and
vitamin C) were estimated in all the subjects by
using spectrophotometer.
Results: Ischemic stroke cases had significantly
lower levels of enzymatic and non enzymatic
antioxidants, compared to controls which is
statistically significant (p<0.05). The Group L
ischemic stroke cases had statistically significant
(p<0.05) lower levels when compared to Group S
ischemic stroke cases.
Conclusion: The antioxidant activity of serum may
be an important factor providing protection from
neurological damage caused by stroke-associated
oxidative stress. The present study suggest that
reduced antioxidant status may be used as an
indirect evidence of oxidative stress induced
neuronal damage in acute ischemic stroke which
may be useful for monitoring and optimizing
antioxidant therapy.

Background: Lipid peroxidation has been
suggested to play a key role in the oxidative
modification of LDL (oxd-LDL) which stimulate
the production of auto antibodies by B-cells and
anti-oxd LDL antibodies are produced. These
antibodies could represent a biological marker of
oxidative stress and serve as markers of
atherosclerosis. Essential hypertension is a major
risk factor for atherosclerosis, recently border line

function tests, albumin & protein levels. The
finding were compared with age & gender, who
had matched persons bacterial pneumonic without
pleural effusion.
Results: Of the 75 patients in the study group
23(31%) had small effusion, 24(32%) had
moderate effusion and 28(37%) had large effusion.
Moderate to severe hypoabluminemia was found
in patients 52% of the study group 6% of the
patients with pneumonic without pleural effusion.
Means serum albumin level was lower in patients
with large pleural effusion than in patients with
small effusion (2.66+/- 0.37 vs 3.66+/-0.47 g/dL).
There was no evidence of albumin loss or
significant malnutrition. Estimation of the amount
of albumin in the drained pleural fluid suggested
an albumin shift from blood to pleural fluid.
Conclusion: The Significant hypoabluminemia is
common with patient of parapneumonic pleural
effusion. Large effusion are associated with low
serum albumin levels, which might be explained
in part by a shift from blood to the pleural fluid.

Objective: JNK /SAPK (Stress activated protein
kinase) activation plays an important role in the
intestinal inflammation in patients with
inflammatory bowel disease (IBD), ulcerative
colitis and Crohn’s disease. Several types of stress
and allergens disrupt intestinal epithelial barrier
function and enhance mucosal permeability. The
312
major component of mucosal barrier function is
epithelial tight junctions (TJs) and therefore, stressinduced inflammatory diseases are likely to be
initiated by the disruption of TJs and induction of
barrier dysfunction.
Methods: Dextran sodium sulfate (DSS)-induced
murine colitis is widely used model for human
colitis/IBD. We investigated the role of JNK in
mediating the DSS-induced disruption of barrier
function in Caco-2 cell monolayers. Barrier
function was evaluated followed with the exposure
to 2% DSS by measuring transepithelial electrical
resistance (TER) and inulin flux. TJ integrity was
assessed by confocal microscopy. Role of JNK
in DSS-induced TJ disruption was determined by

redistribution of occludin and ZO-1 from the
intercellular junction into the intracellular
compartment. DSS rapidly increased the level of
phosho-JNK. Pretreatment with SP600125
significantly attenuated DSS-induced decrease in
TER, increase in flux and redistribution of TJ
proteins. DSS-induced tyrosine-phosphorylation of
TJ proteins was inhibited by the pretreatment of
SP600125.
Conclusion: These studies indicate that DSS
disrupts tight junctions of Caco-2 cell monolayer
by JNK activity dependent mechanism which
involves tyrosine-phosphorylation of TJ proteins

Objective: Rheumatoid arthritis is an autoimmune
disease, characterised by progressive cartilage and
bone destruction. Normal synovium is a delicate
tissue, lining the joint capsule but in arthritic
condition, the synovium transforms into an
aggressive tumor like structure called pannus,
which invades and erodes the joint. In later stages,
the presence of macrophage, fibroblasts, mast cells
and chondrocyte accumulation is found at the site
of cartilage erosion. However, the pathogenesis of
disease is unclear but activated synovial fibroblasts
appear to play a major role in disease. It is

speculated that their ability to induce and
perpetuate inflammation is associated with the
production of pro-inflammatory cytokines which
inturn results in inflamed synovium.
Methods: Arthritis was induced in mice by
injecting the Freund’s Complete Adjuvant in the
foot pad. A booster dose was given on the day
12 th . Nyctanthes arbor tristis extract was
administered orally from the day of induction of
disease.
Results: On the day 47th animals were sacrificed
and the ankle joint was processed for the
histopathology. Infiltration of inflammatory cells,
neovascularisation and cartilage damage was
found negligible in the extract treated animals as
compared to the arthritic one. The cell lining was
also observed intact in Nyctanthes arbor tristis
extract treated animals as compared to the control
animals.

* Dept of Biochemistry, SBH: Govt.Medical College, Dhule, ** Dept of Biochemistry, SDN Medical
College, Dharwad .Email: [email protected]
Background: In the last few years the herbal
medicine and drugs are gaining popularity,
because of their natural origin and less side effects
compared to modern synthetic chemical
compounds. To date, over 400 traditional plant
treatments for diabetes have been reported,
although only a small number of these have
received scientific and medical evaluation to
assess their efficacy. There are several mechanisms
through which these herbs act to control the
glucose level, majority of the actions remains
unexplored. The purpose of this study was to
evaluate the possible hypoglycemic actions of a
polyherbal mixture of 17 ingredients which are
commonly used as food and in other herbal
treatments.
Objective: The present study was designed to
investigate the effect of a polyherbal drug, on
blood glucose, glycosylated haemoglobin and
insulin level in alloxan-induced diabetic rats.
Group 1: normal rats given 2 ml of saline; group
2: normal rats given aqueous solution of drug (0.25
g/kg of body weight); group 3: diabetic control
rats given 2 ml of saline; group 4: diabetic rats
given aqueous solution of drug (0.05 g/kg of body
weight); group 5: diabetic rats given aqueous
solution of drug (0.10 g/kg of body weight); group
6: diabetic rats given aqueous solution of drug
(0.20 g/kg of body weight) and group 7: diabetic
rats given aqueous solution of Metformin (500 µg/
kg of body weight). The treatment was given for
30 days. After the treatment, fasting blood glucose,
plasma insulin and glycosylated haemoglobin were
determined in normal and experimental animals.
Results: Treatment with drug resulted in a
significant reduction in blood glucose,
glycosylated haemoglobin value, but plasma
insulin level did not show any significant change.

Objective: Cancer being one of the leading causes
of mortality in the world, preventive measure is
the most cost effective long term strategy for
combating the disease. Recently, naturally
occurring polyphenolic antioxidants obtained
from fresh fruits and vegetables have been
identified as potential chemopreventive agents.
Due to lack of substantial data about crude
polyphenolic extracts from Indian grapes, this
study was carried out to evaluate the biological
activity of the extracted polyphenols on stratified
epithelial cell lines (HaCaT and AW-13516).
Methods: The grape varieties selected for the
study were namely Pandhari sahebi (PS) and
Thompson seedless (TS). The crude extracts were
analysed for their polyphenol content as well as
antioxidant activity using gallic acid as the
standard.
Results: The polyphenolic content of both the
varieties were around 1.5mgs gallic acid / gm
freeze dried powder but the seed showed a very
high polyphenol content and IC50 value was 78µg/
ml. Sulphorhodamine B assay was carried out on
the transformed (AW-13516) and non transformed
(HaCaT) cell lines and it was found that PS
polyphenolic extract was more effective as
compared to the TS polyphenolic extract in causing
cell growth inhibition. Also the effect seen was
greater on the transformed cell line as compared
to the non - transformed. A rapid assessment survey
was undertaken in order to know the awareness of
grape polyphenols among consumers and it was
seen that about 69% of the consumers were
unaware of polyphenols and hence there is a need
to spread awareness regarding the same.

Diet pattern of a population depends largely on
the traditions, availability of food items,
agricultural and fruiticultural output. Due to
globalization, easy storage and transportation the
products from one corner of the world are available
all over. Yet, the search for a perfect diet continues
especially with reference to promotion of health
and prevention of chronic life style diseases such
as cardiovascular diseases, cerebral strokes,
neurological disorders, diabetes and even some
type of cancers. A large number of studies have
been made on the role of various food components
like simple and complex carbohydrates, saturated,
unsaturated fats, and fibers in food, minerals and
water in connection with the incidence of chronic
life style diseases. The results have lead to
confusing recommendations from time to time.
The role of free radicals induced damage and its
prevention by antioxidants has been widely

described in these conditions. Sometimes
increased intake of antioxidants has resulted in
increased incidence of disease which it intended
to prevent such as carotene and smoking induced
lung cancer. More often, the intake of antioxidant
supplements such as Vitamin E, C and Polyphenols
including Flavanoids had little effect.The search
for a perfect diet continues unabated to promote
health and prevent ageing and disease.

Objective: Hepatitis is well known common liver
dysfunction all over the world. There are different
types of jaundice like Infectious hepatitis,
Obstructive jaundice, Alcoholic hepatitis, Malerial
hepatitis; Drug induced jaundice, Cirrhosis of
liver, Viral hepatitis (A to G). It is generally due
to long-term alcohol abuse, infection, or exposure
to various chemicals and drugs. A condition
characterized by yellowness of skin and eyes,
mucous membranes and body fluids due to
deposition of bile pigment resulting from excess
bilirubin in blood (hyperbilirubinanemia). Some
allopathic medicines are known to cure hepatitis.
However, their recovery is very slow and having
side effects of their own. Literature reviews reveal
that the herbal medicines are found to be more
effective for different types of liver dysfunction.
Hence, herbal medicines provide a wide scope in
attempting cure and treatment of liver dysfunction,
in general known as jaundice. Active principles
extracted from plants like phyllanthus niruri,
silybum marium etc. are showed to be effective
against liver dysfunction. Herbs have pronounced
hepatoprotective activity and would be useful tool
in controlling and treating jaundice. An attempt
was done to do comparative study of extraction,
identification, separation and characterization of
herbal active principles from medicinal plants and
to compare the characteristics.
Methods: The present study involves isolation of
phyllanthin a metabolite from the plant of
phyllanthus niruri and silymarin from silybum
marium and comparison of antioxidant activity of
the total extract with the isolated compounds. The
antioxidant
activity
was
compared
spectrophotometrically using DPPH.
Results: The results reveal good antioxidant
activity as compared to standard used ascorbic

Objective: Diabetes mellitus is a clinical
syndrome characterized by a common phenotype
of hyperglycemia and dyslipidemia with
subsequent derangement of carbohydrate, Lipid
and protein metabolism. Fruit of Withania
coagulans is used in the traditional Indian system
of medicine for the treatment of diabetes mellitus.
Our aim was to investigate the hypoglycemic and
hypolipidemic effects of aqueous extract of fruits
of Withania coagulans in alloxan induced diabetes
mellitus in rats.
Methods: Diabetes was induced by intraperitoneal
injection of alloxan at dose of 100mg/kg b.wt. Rats
weighing 150-200gm were divided into three
groups of six each, Group I healthy control, Group
II diabetic control and Group III Diabetic rats
treated with Withania coagulans at dose of 250
mg/kg b.wt./day orally for 30 days.
324
Results: The Group II, rats showed increased
fasting & postprandial blood sugar, serum
cholesterol, triacylglycerol levels and decreased
level of HDL as compared to Group I. Treatment
with water extract of Withania coagulans,
significantly decreased fasting and postprandial
glucose levels in group III as compared to group
II diabetic control rats (p<0.05). Serum cholesterol
and triacylglycerol levels also decreased
significantly in diabetic treated rats as compared
to group II (diabetic rats) (p<0.05), while HDL
level increased as compared to Group II diabetic
control rats (p<0.05). Glycosylated hemoglobin
(HbA1c) was 8.79 in diabetic group which
decreased to 5.9 in WC treated group While GHb
A1c of healthy control was 4.65.
Conclusion: These results show that water extract
of fruit of Withania coagulans has potential to be
used in the treatment of diabetes mellitus.

Nutraceuticals are defined as food or parts of food
that provide medical or health benefits including
the prevention or treatment of diseases. Many
plant derived foods and beverages contain the
class of nutraceuticals known as polyphenols. As
such plant polyphenols are important constituents
of human diet and a number of these are
considered to possess chemopreventive and
therapeutic properties against cancer. They are
recognized as naturally occurring antioxidants but
also act as prooxidants catalyzing oxidative DNA
degradation in the presence of transition metal ions
such as copper. Using human peripheral
lymphocytes and Comet assay we have shown that
polyphenols are capable of causing cellular DNA
breakage. Incubation of lymphocytes with
neocuproine (a cell membrane permeable Cu (I)
chelator) inhibited DNA degradation confirming
that Cu (I) is an intermediate in the DNA cleavage
reaction. Bathocuproine, which is unable to
permeate through the cell membrane, did not cause
such inhibition. Further we have shown that
polyphenols are able to degrade DNA in cell nuclei
and that such DNA degradation is inhibited by
neocuproine as well as bathocuproine (both of
which are able to permeate the nuclear pore

bind iron and zinc (desferrioxamine mesylate and
histidine respectively). Copper is a major metal
ion present in nuclei and it is well established that
tissue, cellular and serum copper levels are
considerably elevated in various malignancies.
Therefore cancer cells may be more subject to
electron transfer between copper ions and
polyphenols to generate reactive oxygen species.
Such a common mechanism would better explain
the anticancer effects of polyphenols with diverse
chemical structures as also the preferential
cytotoxicity towards cancer cells

Objective: Ocimum sanctum, a traditional
medicinal plant of India, showed significant
abilities of scavenging superoxide, hydrogen
peroxide radicals and inhibiting lipid
peroxidation. Wagatea spicata, a medicinal plant
found in Western Ghats of India is also potent
scavenger of highly reactive superoxide and
hydroxyl radicals.
Methods: In the present study we evaluated Nitric
oxide(NO) and Hydrogen Peroxide(H 2 O 2 )
scavenging abilities of the plants in comparison

with known antioxidant Ascorbic acid. Shade dried
plant material powder was extracted with water,
fractionated with different solvents. Total phenolic
and flavonoid content of the plant materials were
analyzed through spectrophotometry. NO was
generated from sodium nitroprusside and
scavenging action was measured by the Greiss
reduction. H2O2 scavenging action was measured
by peroxidase based assay system.
5 ± 1.4µg /ml, 6.5 ± 2.9µg /ml respectively which
is almost equal to that of ascorbate. Wagatea
showed significant NO scavenging action than
ocimum. Flower and bark extracts, their methanol
and water fractions of Wagatea showed NO
scavenging activity having IC50 at 10 ± 7µg/ml.
Free radical scavenging action of Wagatea spicata
and Ocimum sanctum can be correlated with its
phenolic and flavonoid rich plant materials.
Results: Botanical extracts of both the plants
showed concentration-dependant inhibition of
H2O2 and NO. Ocimum leaves showed better
scavenging of H2O2 than Wagatea. Crude extract
of Ocimum showed IC50 at 18.5 ± 6.2µg/ml,
ethyl acetate and diethyl fractions having IC50 at
Conclusion: These results indicate that both these
plants can scavenge deleterious NO and H2O2
radicals at low concentration. Phenolic and
flavonoid rich Ocimum and Wagatea can be
supplemented as antioxidant equivalent to
ascorbate.

Objective: Cardiovascular diseases are one of the
leading cause of morbidity and mortality in
developed as well as in developing countries,
therefore its prevention is a major public health
challenge. Oxidative stress plays a potential role
in CAD and it has been reported to accelerates
atherosclerosis. Terminalia arjuna is traditionally
used for the treatment of heart diseases.
Methods: The present study was undertaken to
demonstrate the effect of hydroalcoholic extract
of Terminalia arjuna bark on lipid peroxidation,
reduced glutathione and superoxide dismutase to
evaluate the antioxidant activity in experimentally
induced myocardial infarction in rats and then
sacrificed for histopathological investigation.24
male albino rats weighing 200-250g were divided
into three groups (n=8 in each groups).Healthy
control (groupI) were given normal saline for 30
days. Isoproproterenol treated rats(groupII) was
given normal saline for30 days, Isoproterenol

(85mg/kg b.w) administered Subcutaneously on
29th and 30th day. To drug treated rats (groupIII)
hydroalcoholic extract of T. arjuna (HETA), orally
administered for 30 days at a dose of 100 mg/kg
b.w, Isoproterenol administered SC on 29th and
30th day. Fasting blood samples were taken prior
to and after given the treatment to estimate MDA,
GSH and SOD, and then sacrificed for
histopathological examination.
Results: HETA produced significant depletion in
MDA with a concomitant elevation in activity of
SOD. GSH level was also significantly increased
by HETA (p< 0.001).Histopathological studies
showed area of necrosis in isoproterenol treated
rats.
Conclusion: The results suggest that crude bark
of TA augments endogenous antioxidant
compounds of rat heart and also prevents oxidative

hippocampus of Al3+ treated rats as observed in
the Electron microscopy (EM) images indicates
early aging and its similarities with Alzheimer
disease, which reflects its direct correlation with
lower MTR value. Significantly elevated value of
MTR following 90 days co-administration of
Brahmi when compared with Al3+ and DP treated
rats.
Methods: In the present study, male albino rats
were administered with AlCl3 (100 mg / kg body
weight) for 90 days and simultaneously treated
another groups with 40mg and 2.5 mg / kg body
weight with Bacopa monnieri and Donepezil
respectively. Serum and urine was used to asses
the markers of metabolic disturbances followed
by the behavioral and MRI-MTC imaging of rats.
Furthermore, ultrastructural changes were also
evaluated in the hippocampus.
Conclusion: On the basis of the results of the
present study, we conclude that Al may be
responsible for neurolipofuscinogenesis and
alteration in neurobehavioral activity and these
changes may be responsible for the development
of age related diseases like Alzheimer’s disease
and Bacopa monnieri might be used as
neuroprotective agent.

Organophosphorous (OP) pesticides can develop
lowered cholinesterase levels; therefore regular
checking of their AChE levels should be done.
Nearly all the insecticides have the potential to
significantly alter the ecosystem. In humans, they
are responsible for acute poisonings as well as
for long term health effects, Organophosphates
and Carbamates are, nowadays, widely used as
insecticides. These compounds can cause toxicity
through all routes of exposure-dermal, oral,
respiratory and, even, ocular. They exert their
effect mainly by the inhibition of
Acetylcholinesterase (AChE), an enzyme that
328
occurs in the CNS, which functions by removing
acetylcholine (ACh) from its postsynaptic
receptors.
Methods: The present study was conducted on 38
subjects working as Multipurpose Health Workers

Lead Poisoning in Residential Areas Near Drainage Systems in Bangalore
Anitha Jerry Juneeja Varghese and Antony.P.U
Under the guidance of Dr. Venkatesh. T
With the accumulation of lead containing
substances in drainage systems, there is a
possibility of this lead-contained water to seep into
the groundwater and to be used by the residents
of the nearby area. In which case, the water might
be able unusable. This was checked by a study
done in a few areas of Bangalore near large
drainage systems. Both bore well and normal well
water samples were collected and tested for their
level of lead concentration. Most results remained
within the prescribed limits, except for a few odd
samples. The variation in the few samples can be
ascribed to the activities in the surrounding areas
and certain human errors that could have occurred
during the course of the sample collection. This
showed that the water used in residential areas near
large drainage systems were free from the harmful
concentration of lead and was safe for use.

A Brief Study of Lead Poisoning Among Children
Faculty and Students
Dept. Of Biotechnology, NMKRV College for Women, Bangalore; E-mail id:
[email protected]. Ph.No: 080-26643499
Children are more susceptible to lead poisoning
because their bodies are still developing and their
body’s tend to retain more lead than adults. 30
students from Byramangala government school
were tested for blood lead levels. The criteria for
choosing Byramangala as the study area was that
the untreated domestic sewage of Bangalore city,
effluents of various small scale industries are
released into Vrishbhavati River which in-turn
enters the Byramangala reservoir throughout the
year. The water and vegetable samples consumed
by these children were analyzed using Atomic
Absorption Spectrophotometry. Blood lead levels
was analyzed using Anodic Stripping Voltametry
using an ESA 3010 lead analyzer. The atomic
absorption spectrophotometry showed that the
vegetable and water samples had lead levels in
“Below Detection Levels” (BDL) and thus may
be ruled out as possible sources of lead poisoning.
However the results of the blood analysis obtained
remained a cause for concern, as 10% (3 Nos.)
were having high blood lead levels, 27% (8 Nos.)
were on the borderline, indicating the fact that
almost 37% of children have or are on the verge
of lead poisoning. The reasons for such high blood
lead levels needs to be further investigated and
awareness has to be created among the people
living in that area.

Antitumour Activity of Some Homoeopathic Medicines in Animal Models and
Possible Mechanism of Action

Homoeopathic medicines are practiced in many
Western as well as in Eastern countries. Even
though clinical use of homoeopathic medicines
against several diseases has been well documented
its scientific acceptability is still questionable due
to the lack of well carried out clinical trials as well
as evaluation of these medicines in a scientific
manner. Several homoeopathic medicines have
333
been prescribed in cancer. In the present study we
have evaluated the use of homoeopathic preparation in the laboratory using modern techniques.
Initial studies conducted to find out the cytotoxic
potential of potentiated homoeopathic drugs indicated that the some of the potentiated
homoeopathic medicines produced cytotoxicity to
various cell lines and inhibited T-thymidine uptake. Moreover these preparations were found to
inhibit the tumour development induced by
Dalton’s lymphoma ascites (DLA) cells and
Ehrlich ascites carcinoma cells in mice. Potentiated preparation of Hydrastis was found to cure
the developed tumours in mice produced by DLA
cells. Potentiated homoeo drugs were also found
to inhibit the chemical carcinogenesis induced by
3-methylcholanthrene and nitrosodiethylamine.
Mechanism of action of homeopathic drugs indicated that some of the mother tincture as well as
their potentiated preparation had similar activity.
For example mother tincture of Ruta as well as its
200C potentiated preparation induced chromosomal aberrations and DNA damage in vitro and
in vivo. Moreover some of the preparations were
found to induce apoptosis to tumour cells as seen
in morphology and induction of marker enzymes
as well as by Tunnel assay. This was also substantiated by microarray analysis in which several
genes involved in apoptotic pathway were found
to be elevated by treatment with these preparations. It was also found that some of these preparations induced ROS generation in the cells and
this may be a major initiating agent to induce DNA
damage as well as apoptosis.

XRCC – 1 Polymorphisms (Arg194Trp and Arg399Gln) in Oral Cancer from a
Kerala Population.
Balaji Natarajan
Background : Oral cancer is one of the leading
cancers in India. In particular, the state of Kerala
has one of the highest incidence of oral cancer in
the world. The status of DNA repairing gene
XRCC1 genotypes Arg194Trp (exons 5, 6) and
Arg399Gln (exons 9, 10) in Oral cancer is to be
determined by the following study.
samples were selected from the repository for this
study. DNA isolated from these samples was amplified using PCR technique. Restriction digestion
of the amplified gene was performed using Pvu II
& Nci I enzymes respectively to detect polymorphisms in the two XRCC 1 genotypes. The patients
were classified into risk groups (cigarettes, betel
quid, pan, alcohol or tobacco) and no-risk groups
Methods : Tissue samples (normal & tumor) were based on their lifestyle.
collected from individuals diagnosed with carcinoma at The Head and Neck Institute. 15 tissue Results: The results so obtained were combined
335
with the results available in the lab for the purpose of analysis. So, a total of 30 patients were
analyzed. Analysis of exons 5, 6 revealed that only
1 patient was homozygous for Trp194Trp, while
2 (7%) were heterozygous (Arg194Trp) and the
rest (90%) showed the Arg194Arg genotype. Exons 9, 10 analysis indicated that 8 (26%) were
Arg399Gln heterozygous, while none were homozygous for Gln399Gln. Amongst the risk group,
only 6 patients exhibited polymorphism.
Conclusion: Our study showed an increase in the
Arg399Arg heterozygote in our study population,
suggesting a marginally increased risk of HNSCC
associated with this allele, as supported by other
studies, especially in other Asian populations. It
is of much concern that Arg194Arg was seen in
90% of patients. This is in accordance with other
studies that this may be the risk factor.

Aim: The study was carried out to determine the
incidence of Multiple Myeloma in Kerala population and to study the age and sex wise distribution as well as to analyze the type of immunoglobulin.
Methods: Past one year multiple myeloma cases
of all sample received for electrophoresis in the
EI Lab Metropolis Laboratory was analyzed.
Results: Out of the 12000 sample received for
electrophoresis 2.5% were having multiple myeloma band. 70% of which were showing thick M
Band at gamma region while 15 % were between
gamma and beta region and the remaining 15% at
beta region. The male female ration was 1.1 suggesting a slight prevalence of the disease in male
population. Number of case at age below 40 were
very less 1% (100% Male), between 41 and 50
were 9% (60% Male, 40% Female), between 51
and 60 were 21% (43% Male, 57% Female), between 61 and 70 were 32% (41% Male, 59% Female), between 71 and 80 were 27% (58% Male,
42% Female) and between 81 and 90 were 10%
(78% Male, 22% Female)
Conclusion: The incidence of multiple myeloma
in Kerala population may be higher than the national and international 0.8 to 1.2 per lakh. Even
though there is a higher incidence there is no considerable gender difference in this population.
Most of them gives a band in the Gamma region.

EI Lab Metropolis, North Square, Parmara Road, Opp. Town Hall, Cochin-18
Aim: The objective is to study the pattern of
thyroid antibodies in thyroid patients of Kerala.
336
Methods: The seven analytes of the thyroid profile
(thyroid stimulating hormone (TSH),
Triiodothyronine(T3), Thyroxine(T4), Free T3
(FT3), Free T4 (FT4), Thyroglobulin
antibody(ATA) and anti thyroid peroxidase
antibodies (anti-TPO)) were estimated and 218
samples with anti-TPO values above the normal
cutoff of 60 IU/ml were analyzed. All samples
were analyzed using direct chemiluminescence
method on Advia Centaur (Siemens).
Results: 91% of the cases were female while 6%
male and 3% were children. The incidence is
highest during the third decade of life in females
and during the 4 decade in men and then shows a
decline. 77% of the case were having a Anti TPO
values between 60 and 500 and 16% were having
very high titre of more than 1300 IU/ml. Almost
50% of the cases were showing a Normal ATA
level, 32% had an ATA between 61and 250 IU/ml
while 12% showed a high titre of more than 500
IU/ml. 10% of the total were showing a high titre
of both Anti TPO and ATA. The average TSH level
were 5.95.
Conclusion: The incidence of autoimmune thyroid
may be high in Kerala population which needs
demographic studies. Autoimmune antibodies
were predominant in female of reproductive age
group, may be mainly due to the postpartum
hypothyroidism. There is considerable percentage
of high autoimmune titre patients.

Plasma Myeloperoxidase in Diabetes Mellitus
Usha Anand, Vijaya D, Gayathri B, Aruna V and Anand CV
Department of Biochemistry, PSG Institute of Medical Sciences and Research, Coimbatore-641004.
Objective: Myeloperoxidase (MPO) is an
enzyme normally present abundantly in
neutrophil granulocytes. It has been shown that
MPO serves as a link between inflammation and
cardiovascular disease (CVD). It is known that
endothelial dysfunction develops early in
diabetes mellitus (DM), preceding clinically
detectable atherosclerosis. This study was aimed
at determining the levels of plasma MPO in
patients with an established diagnosis of type 2
DM.
Methods: Plasma MPO was determined in 100
patients with type2 DM and 43 controls by a
spectrophotometric method. HbA1c and plasma
fasting glucose were estimated on Cobas Integra
400 plus autoanalyzer.
Results: Plasma MPO (mean ± SD) was 600.7 ±
566.1 U/L in the DM group and 270.3 ± 156.5
U/L in the control group. It was significantly
higher (p< 0.001) in the DM group as compared
with the control group. There was however, no
statistically significant correlation between plasma
MPO and plasma glucose in both groups. The
HbA1c in the DM group also did not correlate with
plasma MPO in the DM group.
Conclusion : MPO is a pro-oxidant that is released
from the granules of activated neutrophils. It has
been shown to oxidize low-density-lipoproteins
rendering them more atherogenic. It could lead to
the consumption of nitric-oxide causing
endothelial dysfunction. Raised levels of this
enzyme could serve as an indicator of
cardiovascular risk in patients with DM. The lack
of correlation between the glycemic status and
MPO seems to indicate that this enzyme might not
be directly involved in the glycation of
hemoglobin.

Objective: Serum creatinine (Scr) is routinely
used in order to assess renal function. Serum
cystatin C (Scys) has been proposed as an
alternative parameter for the determination of
glomerular filtration rate (GFR). This present
study was carried out to compare these two
parameters in patients with various stages of
chronic kidney disease.

urban and rural people in terms of hyperglycemia,
socioeconomic position (SEP) and hypertension
in community based survey in sunsari district of
eastern Nepal.
Methods: Blood glucose levels from participants
(n=2006) e” 30 years of age from urban and rural
population were classified according to WHO
criteria (1998) into normoglycemia (NGY),
impaired fasting glucose (IFG), impaired glucose
tolerance (IGT) and hyperglycemia (HGY)
groups. Moreover, both IFG and IGT is considered
as glucose intolerance. SEP was assessed in a
structured health interview along with
Anthropometric measurements and behavioral
variables. Hypertension was classified as per Joint
National Committee (JNC-VII) criteria.
Results: About 10.26% subjects (urban-13.3% &
rural-11.0%) in this survey had given the family
history of diabetes. Within the participants, who
experienced no past history of diabetes 70(9.51%)
HGY and 143(19.42%) glucose intolerance were
identified in urban population (n=736) and
114(8.97%) HGY and 176(13.85%) glucose
intolerance in rural population (n=1270).

My Experience of Two Decades Using Mid Size Laboratory Automation in Clinical
Laboratory Practice
Dr. Ulhas R. Tendulkar, Director, Ambalab, Goregaon East, Mumbai-400063
A lab practitioner needs around 5 to 7 years to
establish and acquire significant reputation in laboratory medicine. Thereafter it is advisable to think
on laboratory automation. Once this decision is
taken, then mobilization of resources has to follow. Proper selection of equipment, preferred vendor and financial provisions are essential. The
issues like cost benefit ratio, turn around time, in
house training for self and staff needs to be taken
care of. Thereafter, break even ratio and profits
need not be overlooked. I have gone through all
these ordeals over a span of two decades.
340
My personal experience states that 1. Break even
ratio is achieved in 2 to 3 years. 2.Substantial financial returns were obtained after 3 years. 3.Client satisfaction was achieved within one year, on
the pretext that the laboratory has moved towards
latest technological developments. 4.In house
training was completed within two weeks after
installation. 5. Bulk work load could be processed
without increasing staff. 6. Other issues such as
interfacing of equipments, computer networking,
calibration of dispensing system, dispatch of reports could be handled in effective manner. 7. The
miscellaneous issues such as finance and material management, laboratory administration participation in quality assurance programmes (both
internal and external) could be tackled without
much difficulty.
The limitations of laboratory automation which I
have faced are: 1. Financial repercussions. 2.
Persuasion of the client on cost hike. 3. Equipment maintenance.
Considering above aspects it is still advisable for
an individual laboratory practitioner to opt for automation to keep pace with latest developments in
laboratory medicine. The pros and cons of this
approach will be discussed.

Department of Biochemistry, AV Medical College, Pondicherry
*Technical Director, Helini Biomolecules, Chennai
#Department of Physiology, AV Medical College, Pondicherry
Background: The prevalence of diabetes mellitus
is very high in urban Indian adults. The literature
have identified a clinical subset where maternal
pedigrees with mitochondrial DNA (mtDNA)
mutations, having diabetes mellitus associated
with sensorineural hearing impairment. This entity
is also known as MIDD. The most commonly
reported such mutation of mtDNA occurs by
substituting guanine for adenine (A-to-G) at
position 3243 of leucine transfer RNA
(tRNALeu(UUR)).
Objective: To identify a molecular tool to detect
the mtDNA mutation much faster, economical and
less labor intensive so as to use it as screening
procedure for relevant patients.
Methods: Before conducting the study we
received the necessary Institutional Ethical
Committee (IEC) clearance certificate, necessary
consent was taken from the patient as well as from
control patient. PCR-RFLP, PCR followed by
allele specific sequencing and PCR-ARMS
technique was used to detect the point mutation.
The PCR product was visualized by agarose gel
electrophoresis. To validate the results both control
and patient sample were send for DNA sequencing.
The sequence data was compared using
bioinformatics tools.
Resulst: We found PCR-ARMS was satisfying our
objective. Successful PCR resulted; a single 475
bp PCR product from control sample and two PCR
products [275bp and 475bp] are observed in test
sample. Validation was done as mentioned above.
Other protocol were laborious, time consuming,
involving many step.
Conclusion: We conclude PCR-ARMS was the
best amongst the three tools for the detection of
point mutation in mtDNA .
