摘要 目的观察卡托普利对高同型半胱氨酸血症(Hhcy)大鼠心肌再灌注无复流相关因子Caspase-3、超氧化物歧化酶(SOD)活性的影响。方法 SD大鼠随机分为正常对照组、Hhcy模型组、卡托普利组,每组10只,雌雄各半。于实验结束后取各组大鼠血浆检测同型半胱氨酸(Hcy)、Caspase-3、SOD、乳酸脱氢酶(LDH)、肌酸激酶(CK)水平。结果与正常对照组比较,Hhcy模型组大鼠Caspase-3、LDH、CK含量明显升高、SOD活性明显降低(P<0.01)。卡托普利组大鼠血浆Hcy水平与Hhcy模型组比较无明显变化(P>0.05),但可使血浆Caspase-3、LDH、CK含量降低、SOD活性升高(P<0.01)。结论 Hhcy可使大鼠心肌缺血再灌注损伤加重,卡托普利不能降低血浆Hcy水平,但可增强对大鼠缺血再灌注损伤的抗氧化保护作用,同时可拮抗缺氧诱导的心肌细胞凋亡,从而有效地防治无复流的发生。
