Abstract: Increased generation of oxidants and (or) reduced endogenous antioxidant defense mechanisms are associated with the etiology of diabetic vascular complications. The aim of the present study was to evaluate whether curcumin supplementation increases the vasodilatory effect of cilostazol in streptozotocin induced diabetic rat aorta. Cumulative addition of cilostazol caused concentration-dependent relaxations of thoracic aorta rings. The sensitivity and the maximal response to cilostazol were significantly higher in control than those in diabetic animals. Treatment with curcumin in control rats increased the sensitivity to cilostazol. Further, in aortic rings from diabetic rats treated with curcumin, the responses to cilostazol were significantly increased in comparison to the response in aorta from untreated diabetic rats. It can be conclude, that curcumin increases the cilostazol-induced vasodilation in diabetic rat aorta.
