摘要 目的探讨利多卡因对缺血再灌注离体大鼠心脏Bcl-2与Caspase-3表达的影响。方法 30只SD雄性大鼠随机分为正常对照组(control)、缺血再灌注组(I/R)、缺血再灌注+利多卡因组(I/R+Lid)。I/R组及I/R+Lid组分别灌注30 min后,全心停灌20 min,再灌注40 min,I/R+Lid组于再灌注时在灌流液中加入Lid,正常对照组连续灌流90 min。利用Western印迹法检测Bcl-2,ELISA法检测Caspase-3蛋白的表达情况。结果发现离体大鼠心脏缺血20 min,再灌40 min,导致Caspase-3的表达量为(1.7526±0.02203)(U.mg-1.ml-1pro)明显高于对照组(P<0.05),而Bcl-2减少,利多卡因可明显降低Caspase-3的表达,增加Bcl-2的表达。结论利多卡因可通过增加Bcl-2表达,降低Caspase-3活性而减少缺血再灌注损伤。
