内皮细胞损伤影响内源性NO生成,是心肌缺血再灌注的主要因素之一[1]。减轻或预防心肌缺血再灌注损伤是心内直视手术的关键。本文在离体大鼠心肌缺血再灌注中,应用含左旋精氨酸(L-arg)的心脏停跳液,来研究其对心肌缺血再灌注的作用及机理。材料和方法SD大鼠2
Endothelial cell injury affect the generation of endogenous NO, which is one of the main factors of myocardial ischemia-reperfusion [1]. Reducing or preventing myocardial ischemia-reperfusion injury is the key to open-heart surgery. The purpose of this study was to investigate the effect and mechanism of L-arg on myocardial ischemia-reperfusion in rats. Materials and Methods SD rats 2
