It indicated that the imbalance of endotheliumderivedrelaxingfactor (NO) and the endotheliumderived constricting factor (ET) was a major cause of vasospasm after SAH.
结果表明，脑血流内皮舒张因子和内皮收缩因子之间的平衡紊乱是SAH后脑血管痉挛发生的机制之一。

The finding of endotheliumderivedrelaxingfactor(EDRF) and the illumination of its chemical identity, bio-synthesis and physiological functions promoted greatly the research on vascular disease.
Conclusion: the protective mechanisms of YQTLP were related to inhibit lipid peroxidation, protect endothelium-derivedrelaxingfactor and adjust the fibrinolytic activities.
