Ameliorative effect of Ipomoea pes-caprae ethanolic leaf extract on carbohydrate metabolizing enzymes and oxidative status in Streptozotocin-induced diabetic Wistar rats
Abstract
In diabetic patients, hyperglycemia is developed due to increased hepatic glucose production and impaired utilization of glucose in cells, which leads to oxidative stress in cells. Ipomoea pes-caprae has been widely used as an oral treatment for many diseases. The aim of the present study is to assess the effect of Ipomoea pes-caprae ethanolic leaf extract on carbohydrate metabolizing enzymes and oxidative status in Streptozotocin (STZ) induced experimental diabetic rats. Experimental diabetic rats were induced by intraperitoneal administration of 55 mg/kg b.w of STZ. Diabetic rats were treated with I. pes-caprae ethanolic leaf extract at a concentration of 300 mg/kg b.w and glibenclamide (6 mg/kg b.w) for 45 days. Diabetic rats exhibited significant (P < 0.05) decline in the activity of glucokinase and glucose-6-phosphate dehydrogenase, enzymatic antioxidants (SOD, CAT and GPx) and non-enzymatic antioxidants (GSH, vitamin E and vitamin C), while lipid peroxidation markers (LOOH and TBARS) and glucose-6-phosphatase and fructose-1, 6-bisphosphatase were found to be significantly increased. Further in diabetic rats, the histopathology of pancreas, liver and kidney showed abnormal histo-architecture. The treatment with Ipomoea pes-caprae ethanolic leaf extract notably reversed the abnormal levels in carbohydrate metabolizing enzymes, restored the oxidative status and abnormal structures in pancreas, liver and kidney to near normal levels.
Keywords: Diabetes, antioxidant, lipid peroxidation, Ipomoea pes-caprae and carbohydrate metabolizing enzymes.
