Superior mesenteric artery embolism is responsible for about 30% of cases of acute mesenteric ischemia. In the present study, it was found that Res also induced a relaxant effect in superior mesenteric artery without endothelium, suggesting that Res has a direct effect on vascular smooth muscle cells (VSMCs).
