摘要
目的研究促红细胞生成素(EPO)和血管紧张素受体拮抗剂(ARB)对脑缺血后的脑保护作用。方法采用健康的SD大鼠,线栓法阻断一侧大脑中动脉血流2 h,再灌注24 h,建立局灶性脑缺血再灌注损伤模型(MCAO),治疗组分别予缺血再灌注前后经腹腔注射EPO 3 000 IU/(kg·d),或缬沙坦40 mg/(kg·d),评价大鼠神经功能,测定其脑梗死体积占全脑体积的百分比、脑组织的含水量。结果与缺血再灌注组相比,EPD处理组可改善神经功能缺失,减少脑梗死体积,降低梗死组织含水量,且经EPD预处理,改善更明显,差异有统计学意义(P<0.05);与缺血再灌注组相比,ARB处理组可减少脑梗死体积,降低梗死组织含水量,差异有统计学意义(P<0.05)。结论 EPD和ARB可减少脑梗死体积,降低梗死组织含水量,EPD可明显改善神经功能缺失,经EPD和ARB预处理改善更为明显,具有良好的脑保护作用。
