摘要 目的探讨大鼠脑缺血再灌注损伤对血脑屏障内皮屏障抗原(EBA)及通透性的影响。方法 20只雄性SD大鼠随机分成为缺血再灌注组和假手术组,采用阻断大鼠一侧大脑中动脉(MCA)血流2h、再灌注24h制成局灶性脑缺血模型。24h后断头取脑,制作冰冻切片,免疫组化染色检测血脑屏障EBA和Fibrinogen的表达。结果缺血再灌注组EBA免疫反应阳性血管数5.30±1.24,假手术组EBA免疫反应阳性血管数15.20±1.02,两组比较差异有统计学意义(P<0.01)。缺血再灌注组Fibrinogen免疫反应阳性血管数8.60±3.12,假手术组Fibrinogen免疫反应阳性血管数1.30±0.46,两组比较差异有统计学意义(P<0.01)。结论脑缺血再灌注损伤能显著减少血脑屏障EBA表达,增加血脑屏障通透性。
