摘要
目的 探讨雌二醇预处理对离体大鼠缺血 再灌注心肌的保护作用。方法 采用Langendorff装置建立大鼠离体心脏缺血 再灌注模型 ,将大鼠随机分为对照、治疗及预处理组。治疗组在缺血期给雌二醇 3.3mg·L -1,预处理组于灌注期给药 ,对照组不给药。结果 与对照组和治疗组相比较 ,预处理组更有效地降低心肌细胞内LDH、CK和肌钙蛋白I(TnI)的释出量。电镜观察预处理组心肌细胞损伤小于其他两组。结论 雌二醇预处理对缺血
Objective To explore the protective effect of estradiol preconditioning on the myocardium of isolated ischemic reperfused rats. Methods The instrument of Langendorff was used to establish the model of isolated ischemic reperfused heart and male rats were randomly divided into three groups: control, treatment and preconditioning groups. Results Compared with that of control and treatment groups, estradiol preconditioning decreased the release of LDH, CK and intracellular TnI more effectively. Conclusion Estradiol preconditioning produces more protective effect on the myocardium of isolated ischemic reperfused rats.
