目的 :为了探讨一氧化氮 (NO)在实验性缺血再灌注心肌顿抑中的作用及左旋精氨酸 (L -Arg)对其的影响。方法 :选用 2 0只家兔 ,制备心肌缺血再灌注模型 ,随机均分为对照组和L -Arg组 ,分别于缺血前、缺血 40min及再灌注 2 0min取血检测NO水平 ,相应时点监测心
Objective: To investigate the role of nitric oxide (NO) in myocardial ischemia during experimental ischemia-reperfusion and the effect of L-arginine (L-Arg) on it. Methods: Myocardial ischemia-reperfusion models were selected and twenty rabbits were randomly divided into control group and L-Arg group. The levels of NO were detected before ischemia, 40 minutes after ischemia and 20 minutes after reperfusion, Time monitoring heart
