Abstract

 Background: One of the known complications of diabetes mellitus is vascular dysfunction. Inability of the coronary vascular response to cardiac hyperactivity might cause a higher incidence of ischemic heart disease in diabetic subjects. It has been indicated that regular EXERCISE training and antioxidants could prevent diabetic cardiovascular problems enhanced by vascular damage.Objectives: The aim of this study was to determine the effects of GRAPE SEED EXTRACT (as antioxidant), with and without EXERCISE training on coronary vascular function in streptozotocin induced diabetic rats.Materials and Methods: Fifty male Wistar rats weighing 200-232 grams were randomly divided into five groups of 10 rats each: sedentary control, sedentary diabetic, trained diabetic, GRAPE SEED EXTRACT (200 mg/kg) treated sedentary diabetic and, GRAPE SEED EXTRACT treated trained diabetic. Diabetes was induced by one intraperitoneal injection of streptozotocin. After eight weeks, coronary vascular responses to vasoactive agents were determined.Results: The endothelium dependent vasorelaxation to acetylcholine was reduced significantly in diabetic animals, EXERCISE training or GRAPE SEED EXTRACT administration partially improves this response. However, EXERCISE training in combination with GRAPE SEED EXTRACT restores endothelial function completely. The endothelium independent vasorelaxation to sodium nitroprusside was improved by combination of EXERCISE training and GRAPE SEED EXTRACT. On the other hand, the basal perfusion pressure and vasoconstrictive response to phenylephrine did not change significantly.Conclusions: The data indicated that co-administration of GRAPE SEED EXTRACT and EXERCISE training had more significant effects than EXERCISE training or GRAPE SEED EXTRACT alone, this may constitute a convenient and inexpensive therapeutic approach to DIABETIC VASCULAR COMPLICATIONs.
