عنوان انگلیسی Effect of exogenous leptin on serum levels of lipids, glucose, renal and hepatic variables in both genders of obese and streptozotocin-induced diabetic rats
چکیده انگلیسی مقاله Objective(s): Leptin exerts various effects on appetite and body weight. Disruption of the obesitygene is precedent to fatness. Insulin or glucose elevates leptin, but streptozotocin reduces it. However, controversial data exist for the effects of leptin on diabetes and leptin level in each gender. Leptin can damage the kidney function but little evidence exists for its hepatic effects. The aim of this study was to investigate the probable sex-dependent differences in blood sugar levels, lipid profile, and renal and hepatic biochemical factors in the obesity and streptozotocin-induced diabetic rats after leptin administration. Materials and Methods: Wistar rats of both sexes were randomly divided into two groups, namely obese and diabetic rats. Each group was further divided into male and female subgroups. Extra fat and carbohydrate was added to the diet to induce obesity. Furthermore, streptozotocin (55 mg/kg, IP) was injected to induce diabetes. The treatment groups received leptin (0.1 mg/kg SC) for 10 days, and then, blood samples were taken from the orbital sinus for laboratory evaluations. Results: Leptin resulted in a significant weight loss in both sexes (P< 0.001), food intake reduction in male rats (P< 0.05), LDL reduction in female rats (obese (P< 0.05) and diabetic (P< 0.001)), and glucose level decline in the female diabetic rats (P< 0.001). However, total protein concentration, LFT (liver function tests), urea and creatinin concentrations among different groups did not show any significant changes. Conclusion: Leptin caused some discrepant results, especially regarding the LDL and glucose levels in diabetic female rats.
