Ameliorative effect of Withania coagulans on dyslipidemia and oxidative stress in nicotinamide-streptozotocin induced diabetes mellitus.

Abstract

Present study aims to evaluate the effect of Withania coagulans fruit (aqWC) on diabetic-dyslipidemia and antioxidant/oxidant status in DM. Diabetic animals were treated with aqWC at a dose of 250 mg/kg bw for 30 days. Lipid profile, MDA, GSH, SOD, FRAP, HMG CoA reductase and acetyl CoA carboxylase activities were estimated in blood and tissues. Total cholesterol, TAG and LDL were significantly elevated whereas HDL was decreased in diabetic animals (p<0.05), simultaneously the lipid content and HMG CoA reductase activities were also increased, whereas acetyl CoA carboxylase activity decreased significantly in tissues of diabetic animals. MDA was increased and antioxidants such as SOD, GSH and FRAP decreased significantly in DM (p<0.05). Oral administration of aqWC to diabetic animals produced significant improvement in serum lipid profile and tissue lipid content. Activity of HMG CoA reductase decreased, whereas acetyl CoA carboxylase activity increased significantly in tissues after aqWC treatment. Administration of aqWC to diabetic animals also showed significant increase in antioxidant levels i.e., GSH, SOD, FRAP and reduced level of MDA in blood and tissue homogenates as compared to diabetic controls (p<0.05). These results suggest that aqWC treatment improved lipid profile and decreased oxidative stress in diabetes mellitus.
