Aim: The key pathogenic events involved in Type 2 Diabetes mellitus are impaired glucose regulation and insufficient carbohydrate utilization caused either by the lack of sufficient Insulin or resistance to it. The present study was hypothesized to investigate the beneficial effects of Indigofera cordifolia on hyperglycemia-induced oxidative damage in Streptozotocin (STZ) induced diabetic rats.
Methods: Diabetes was induced by an intraperitoneal injection of STZ (45 mg/kg body weight). The seeds of I. Cordifolia were extracted with 70% methanol and fractionated with n-butanol (ICMB fraction). An oral dose of 500 mg/kg of ICMB was given once a day for 14 days following diabetes induction. At the end of the experimental period, blood was obtained from retro-orbital route. Liver and pancreas were used for estimations of antioxidant parameters while biochemical parameters were estimated in serum.
Results: In the diabetic control group, levels of glucose, SGOT, SGPT, Total cholesterol, TNF-α and IL-6 were significantly increased, while levels of SOD and GSH were decreased. Administration of ICMB fraction significantly reversed these alterations. In-vitro antioxidant assays demonstrated the radical scavenging property of ICMB against DPPH and ABTS radicals. Moreover, ICMB caused significant inhibition of the carbohydrate hydrolyzing enzymes α-glucosidase and α-amylase. Histopathological examinations of pancreas demonstrated increase in the number and size of the islets in the ICMB treated group as compared to the diabetic control group.
Conclusion: Thus, it can be safely concluded that Indigofera cordifolia exerts a protective action against STZ induced hyperglycaemia and inflammation.
