Title

Effect of allopurinol and benzbromarone on diabetic cardiomyopathy and vasculopathy in streptozotocininduced diabetic rats

Pages

  1-8

Abstract

 Introduction: Allopurinol, a xanthine oxidase inhibitor, reduces both plasma uric acid (UA) and oxidative stress, and Benzbromarone, a uricosuric agent, reduces the level of plasma UA. This study was designed to evaluate cardiac mechanical and endothelial functions of the Allopurinol-and Benzbromarone-treated diabetic rats, and to investigate the underlying mechanism (antioxidant or UA lowering activity) of Allopurinol beneficial effects. Methods: Diabetes was induced by injecting streptozotocin to male Spargue-Dawley rats. Diabetic animals were treated with Allopurinol and Benzbromarone. After six weeks of treatment, left ventricular systolic/diastolic functions of hearts, contraction/relaxation responses to phenylephrine and acetylcholine of aortae, and serum levels of malondialdehyde, 8-isoprostane-2α and UA were measured. Results: Diabetic Cardiomyopathy and vasculopathy were characterized by reduced myocardial performance and decreased aortic endothelial response to the vasorelaxation effect of acetylcholine. The serum levels of malondialdehyde and 8-isoprostane-2α levels were elevated in diabetic animals. Allopurinol attenuated the Diabetes-induced diastolic impairment of the hearts, Endothelial dysfunction of the aortae and decreased oxidative stress parameters in serum; however, Benzbromarone had none of these effects. Both, Allopurinol and Benzbromarone, diminished the elevated levels of UA in diabetic animals. Conclusion: Allopurinol improved diabetic Cardiomyopathy and aortic endothelial cell dysfunction in diabetic animals through antioxidant effects.
