本实验复制大鼠缺血再灌注损伤及缺血预处置模型 ,通过观察心肌组织中细胞色素Ｐ450 (ＣＰ450 )含量及室性心律失常严重程度 ,探讨ＣＰ450在心肌缺血再灌注损伤及缺血预处置中的作用。方法 :采用结扎冠状动脉左前降支 60ｍｉｎ和完全放松 30ｍｉｎ的方法复制心肌缺血再灌注损伤
In this experiment, the rat models of ischemia-reperfusion injury and ischemic preconditioning were duplicated. By observing the content of cytochrome P450 (CP450) and the severity of ventricular arrhythmias in myocardial tissue, we investigated the effects of CP450 on myocardial ischemia-reperfusion injury and ischemic preconditioning The role of disposal. Methods: The left anterior descending coronary artery was ligated for 60 minutes and completely relaxed for 30 minutes to replicate the myocardial ischemia-reperfusion injury
