摘要 目的探讨辛伐他汀对全脑缺血/再灌注损伤(cerebral ischemia/reperfusion injury,CIRI)大鼠血脑屏障(bloodbrain barrier,BBB)的保护作用及机制。方法成年SD大鼠随机分为5组,即假手术组、模型组、10 mg·kg^(-1)辛伐他汀组、20 mg·kg^(-1)辛伐他汀组、40 mg·kg^(-1)辛伐他汀组。模型组和辛伐他汀组采用Kouzumi线栓法建立CIRI模型。再灌注后1h,辛伐他汀组给予10~40 mg·kg^(-1)辛伐他汀灌胃,模型组给予生理盐水。再灌注71h后,比较各组神经功能损伤评分、脑组织含水量、脑组织伊文思蓝(Evans Blue,EB)含量。结果模型组大鼠神经功能损伤评分、脑组织含水量、EB含量均较假手术组明显提高(P<0.05)。与模型组相比较,10~40 mg·kg^(-1)辛伐他汀组神经功能损伤评分、脑组织含水量、EB含量显著降低(P<0.05)。结论辛伐他汀对大鼠CIRI所致BBB破坏具有一定保护作用。
