Antioxidant status of streptozotocin diabetic rats.
Free radicals may play an important role in causation and complications of diabetes mellitus. Antioxidant status of blood was determined in rats made diabetic in intraperitoneal injection of streptozotocin (75 mg/kg body weight). The product of lipid peroxidation malondialdehyde in erythrocytes (RBC) was increased in diabetic rats as compared to normal controls after 6 weeks of induction of diabetes. The levels of major natural protective antioxidants, viz. glutathione and alphatocopherol (vitamin E) were lower in RBC and plasma respectively of diabetic rats as compared to normal controls. The results indicate that increased oxidative stress and accompanying decrease in antioxidants may be related to the causation of diabetes mellitus.
