Effect of soybean seeds alone or in combination with insulin or glibenclamide on serum lipid profiles in alloxan-induced diabetic rats

Abstract

The present study was conducted to evaluate the effect of soybean seeds administration alone or combined with either insulin or glibenclamide on serum lipid profiles in diabetic rats. Male Wister rats were induced diabetes by a single subcutaneous injection of alloxan 100 mg/kg.b.w.The rats randomly divided into six groups (eight rats in each group): The first group served as a control, the second group was administered soybean seed 400 mg/kg.b.w orally as suspension, the third group injected insulin 10 I.U/kg.b.w, subcutaneously, the fifth group administered glibenclamide 5 mg/kg.b.w. orally. Accompaniment of soybean seeds with either of insulin or glibenclamide given the fourth and sixth groups, using the same routes and doses in the individual groups. All treatments were once daily for two weeks. Soybean seeds treatment alone resulted in an improvement of body weight and decrease of triglyceride and total lipids levels. While treatment with insulin or glibenclamide as alone or combination with soybean seeds showed a significant reduction in the levels of total cholesterol, triglyceride, low density lipoprotein, and total lipids, beside a significant increase in both body weight and high density lipoprotein. Beneficial effects were seen when soybean seeds combined with either of insulin or glibenclamide treatment. These results indicate the usefulness of soybean seeds in the management of diabetes through the hypolipidemic effects of soybean seeds in diabetic rats.
