The insulin binding of erythrocytes from: (i) fifteen age-matched normal subjects, (ii) ten untreated NIDDM patients and (iii) fifteen treated (glibenclamide + hypocaloric diet) NIDDM patients (all males) has been studied. A significant decrease in specific insulin binding was observed in group (ii) which improved in cases controlled after treatment (group iii). Scatchard analysis of the results suggested that changes in insulin binding were due to alteration in the number of insulin receptors on erythrocytes. The number of insulin receptors/cell was 471 in normals, 160 in diabetics and 282 in treated diabetic subjects. No significant change in the binding affinity was observed in the three groups (1.0 X 10(8), 1.2 X 10(8) and 1.1 X 10(8) M-1 in normal subjects, untreated diabetics and treated diabetics, respectively).

Retrospective glycemic status of diabetic patients: glycosylation of blood proteins in diabetes and chronic renal failure.

In vivo and in vitro studies were carried out to evaluate the clinical application of glycosylated hemoglobin and plasma proteins in the diagnosis and management of diabetes mellitus. Glycosylated hemoglobin registered an almost 80% fall in diabetic patients following controlled glycemia for two months while glycosylated plasma protein level registered an 80% fall in the patients after fifteen days of blood glucose homeostasis. Human serum proteins were glycosylated in vitro and glycosylation was linearly proportional to the glucose concentration and incubation time. Polyacrylamide gel electrophoresis of glycosylated serum proteins revealed that albumin and transferrin are the major proteins that are significantly glycosylated. Glycosylated hemoglobin and plasma protein levels were also increased in chronic renal failure patients without any history of diabetes.

"Effect of short-term cigarette smoking on insulin resistance and lipid profile in asymptomatic adults".

Present study examined the effect of short-term cigarette smoking on insulin resistance and lipid profile in asymptomatic healthy adults. This case control study comprised of 44 healthy male subjects in the age group of 18-40 yrs having BMI 25+3 and WHR < 1.0. Of these 22 smokers were included in the study group and 22 non-smokers in the control group. Subject selection was done such that one smoker and one non-smoker sibling or first degree male relative were selected from the same family. We compared fasting plasma glucose, insulin, lipid profile, and homeostatic model assessment index (HOMA Index) as a measure of insulin resistance between both the groups. Our observation showed that significantly higher values of serum glucose (133.36 +/- 23.45 mg/dl; P < 0.001), serum insulin (32.04 +/- 6.0 2 microU/ml; P < 0.001) and HOMA index (3.62 +/- 0.21; P < 0.001) were found in smokers as compared to non-smokers (serum glucose 86.95 +/- 19.32 mg/dl, insulin 20.09 +/- 4.8 microU/ml, HOMA index 3.29 +/- 0.30). No significant difference was observed for number of subjects having insulin resistance (HI > 3.8) and lipid profile in both the groups. Thus it appears that smokers are prone to develop hyperinsulenemia, hyperglycemia and the metabolic syndrome.
