摘要 目的探讨银杏叶提取物(EGB)对大鼠心肌缺血再灌注时心肌细胞凋亡及凋亡相关基因表达的影响。方法采用结扎左冠状动脉前降支(LAD)30 min,再灌注2 h复制大鼠心肌缺血再灌注模型,分别以缺口末端标记法(TUNEL)及免疫组织化学法检测心肌凋亡细胞、心肌细胞Bcl-2、Bax基因的蛋白表达的变化。结果缺血再灌注(IR)组心肌细胞凋亡数量显著高于假手术组(P<0.0 1),EGB组心肌细胞凋亡明显受到抑制(P<0.0 1)。IR组和EGB组Bax、Bcl-2、P5 3基因蛋白表达均明显增加(P<0.01);EGB明显促进Bcl-2基因表达,同时抑制Bax、P53基因表达(P<0.01),Bcl-2和Bax的比值也随之升高。结论 EGB可明显下调Bax和P53基因的蛋白表达,上调Bcl-2基因的蛋白表达,从而显著抑制心肌缺血再灌注损伤(MIRI)后心肌细胞凋亡。
