摘要 将60只雄性W istar大鼠随机分为假手术组10只和急性心肌梗死(AM I)组50只。AM I组通过结扎左冠状动脉前降支制作AM I模型,成功后24 h剩余36只,再随机分为AM I对照组和干预组各18只。干预组每日予阿托伐他汀(40 m g/kg)灌胃,假手术组和AM I对照组每日予等量生理盐水灌胃。4周后分别采用TUNEL法和RT-PCR法检测非梗死区心肌细胞凋亡指数(MA I)和TNF-αmRNA的表达水平。结果干预组和AM I对照组非梗死区心肌中MA I和TNFα-mRNA的表达均明显高于假手术组(P均<0.05),干预组与AM I对照组相比上述指标均明显降低(P均<0.05)。提示阿托伐他汀可降低大鼠AM I后非梗死区MA I,抑制非梗死区心肌中TNF-αmRNA的表达可能是其机制之一。
