Abstract:

目的探讨大鼠急性心肌梗死后不同时间点心肌组织中p38mRAN、p38蛋白的表达水平及意义。方法健康成年雄性SD大鼠36只,将其随机分为对照组、假手术组和心肌梗死模型组,模型组大鼠开胸结扎冠状动脉前降支以建立心肌梗死模型,成功结扎冠状动脉前降支后1、3、6、12h无痛处死大鼠并获取大鼠心肌组织;对照组大鼠不做任何处理;假手术组大鼠开胸冠状动脉穿线但不结扎冠状动脉;术后均无痛处死并获取心肌组织;分别采用RT-PCR、Westernblot测定大鼠心肌组织p38mRNA及蛋白的表达水平。结果对照组与假手术组之间p38mRNA及蛋白表达的差异均无统计学意义(P>0.05);AMI组大鼠各亚组心肌组织中p38mRNA及蛋白表达均高于假手术组(P0.05)。结论p38可能在心肌梗死后的病理过程中发挥作用。
