Abstract

Abstract Introduction Antioxidants has been utilized to prevent oxidative damage in diabetes and hypertensive diseases. The current study evaluated the effect of α-tocopherol supplementation on blood pressure and the lipid profile in streptozotocin-induced diabetes mellitus in spontaneously hypertensive rats (SHR). Methods The systolic blood pressure and total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides were measured in SHR-diabetes induced. Results Treatment with α-tocopherol (vitamin E) led to a decrease on systolic blood pressure and showed an increase of HDL-cholesterol and a decrease of LDL-cholesterol, but the concentrations of triglycerides and total cholesterol were not changed. Conclusions The vitamin E was able to modulate the blood pressure and the lipidic profile as well, and therefore can be considered as an alternative treatment of lipid disorder found on diabetes and hypertension diseases.
