Background
Resveratrol has beneficial effects on experimental and clinical hypertension and diabetes.Objectives
This study aimed at examining antidiuretic and antihyperlipidemic effects of resveratrol in rats with simultaneous type II diabetes and endovascular hypertension.Materials And Methods
This study was performed on eight groups of male SpargueDawley rats each containing 8 - 10 animals as follows: control, diabetic (induced by streptozotocin and nicotinamide), renovascular hypertensive (induced by placing Plexiglas clips on the left renal arteries), sham, simultaneously hypertensivediabetic receiving vehicle (distilled water), and 3 simultaneously hypertensive-diabetic groups receiving 5, 10, and 20 mg/kg/day resveratrol. Blood pressure and heart rate were measured weekly and fasting blood glucose, serum cholesterol, triglyceride, and markers of oxidative stress were measured after 4 weeks of treatment with resveratrol vehicle. The data were analyzed using one-way Analysis of Variance (ANOVA) and Duncans multiple range tests. Data analysis was done using SigmaStat software and P ≤ 0.05 was considered to be statistically significant.Results
Serum malondialdehyde, systolic blood pressure, heart rate, fasting blood glucose, blood glycated hemoglobin, and serum triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels were significantly higher in the hypertensivediabetic group receiving vehicle compared to the control group (P Conclusions
The findings indicated that resveratrol had antidiabetic, antihypertensive, and antihyperlipidemic effects, which might be partly due to an antioxidant mechanism.Keywords:
