The objective of this study was designed to investigate, evaluate the effect of vitamin E on streptozotocin (STZ)-induced diabetic rats by showing significant changes in blood glucose, water, food intake, lipid profile, serum urea and ceratinine level, and antioxidant enzyme parameters activity. Streptozotocin (STZ)-induced toxicity was studied in male Waster rats; each divided into four groups: G1, GII, GIII, and GIV. Control rats GI, rats treated with vitamin E (GII), STZ-induced diabetic rats (GIII), and STZ-induced diabetic rats treated with vitamin E (G1V). Moreover, vitamin E reduced (p < 0.05) blood glucose and urea, thus, our study improved the lipid profile (reduced the serum levels of amount of total cholesterol, LDL, VLDL, cholesterol and triacyglycerols, and increased HDL cholesterol) and increased total amount protein in STZ-induced diabetic rats (GIV). Vitamin prevented modification in the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSX-Px) and in the concentration of the lipid hydroperoxide. Finally the study suggested that vitamin E improved hyperglycaemia and dyslipidaemia while inhibiting the progression of oxidative stress in STZ-induced diabetic rats.
