摘要

The role of rutin on carbohydrate metabolism in normal and streptozotocin (STZ)-induced diabetic rats was investigated in the present study. Administration of STZ led to a significant (p <0.05) increase in fasting plasma glucose and a decrease in insulin levels. The content of glycogen significantly (p <0.05) decreased in liver and muscle, but increased in kidney. The activity of hexokinase decreased whereas the activities of glucose-6-phosphatase and fructose-1,6-bisphosphatase significantly (p <0.05) increased in the tissues. Oral administration of rutin (100 mg/kg) to diabetic rats for a period of 45 days resulted in significant (p <0.05) alterations in the parameters studied but not in normal rats. A decrease of plasma glucose and increase in insulin levels were observed along with the restoration of glycogen content and the activities of carbohydrate metabolic enzymes in rutin-treated diabetic rats. The histopathological study of the pancreas revealed the protective role of rutin. There was an expansion of the islets and decreased fatty infiltrate of the islets in rutin-treated diabetic rats. In normal rats treated with rutin, we could not observe any significant change in all the parameters studied. Combined, these results show that rutin plays a positive role in carbohydrate metabolism and antioxidant status in diabetic rats.
