摘要 目的探讨七氟醚预处理对缺血再灌注心肌组织保护作用的机制。方法应用24只新西兰白兔制备心肌缺血再灌注损伤模型,后将其随机分成对照组、缺血预处理组、七氟醚预处理组3组,每组8只。取3组动物心肌组织做组织切片,免疫组织化学方法观察3组心肌细胞内Bcl-2水平的表达,利用HPIAS-2000图像分析系统测定Bcl-2表达的平均光密度和平均阳性面积率。结果 Bcl-2在缺血预处理组和七氟醚预处理组心肌细胞内的表达高于对照组,差异有统计学意义(P<0.01);缺血预处理组心肌细胞内Bcl-2表达水平与七氟醚预处理组比较差异无统计学意义(P>0.05)。结论七氟醚预处理对缺血再灌注的在体兔心肌具有重要的保护作用。
