Abstract

Endothelium-dependent relaxations are abolished in the canine basilar artery after subarachnoid hemorrhage. However, the release of endothelium-derived relaxing factor (EDRF) toward the lumen is not reduced. These findings suggest that the responsiveness of the smooth muscle to EDRF is impaired during chronic vasospasm after subarachnoid hemorrhage.

蛛网膜下腔出血后内皮依赖性松弛和慢性血管痉挛。
蛛网膜下腔出血后,犬基底动脉内皮依赖性松弛消失。然而,内皮源性松弛因子(EDRF)向管腔的释放并未减少。这些发现表明,在蛛网膜下腔出血后的慢性血管痉挛期间,平滑肌对EDRF的反应性受损。
