目的 :在在体大鼠模型上原位观察比较了经典缺血预处理对缺血 /再灌注大鼠心肌有关酶活性的影响 ,以期进一步探讨预处理保护作用的机制。方法 :将 2 4只体重 2 0 0～2 5 0 ｇ的雄性ＳＤ大鼠分为 4组 ,即 :Ⅰ组 ,假手术组 ;Ⅱ组 ,缺血 /再灌注组 ,左冠状动脉前降支结扎使心肌缺
OBJECTIVE: To observe the effect of classical ischemic preconditioning on the myocardial enzymes involved in myocardial ischemia / reperfusion in situ in vivo rat models in order to further explore the mechanism of preconditioning protection. Methods: Twenty-four male Sprague-Dawley rats weighing 200-250 g were divided into four groups: group Ⅰ, sham operation group, group Ⅱ, ischemia / reperfusion group, left anterior descending coronary artery Ligation to make the absence of the heart
