摘要
目的 探讨促红细胞生成素(EPO)对大鼠脑缺血再灌注损伤的保护作用。方法 采用阻断大鼠一侧大脑中动脉(MCA)血流2小时,再灌注48小时制成局灶性脑缺血模型。于再灌注开始前,治疗组经腹腔注入EPO(3000 U/Kg);缺血组和假手术组给予生理盐水腹腔注射,48小时后断头取脑。制作 HE切片;以2%氯化-2,3,5三苯基四氮唑(TFC)对脑片进行染色;经图像分析仪计算梗死体积占全脑体积的百分比;同时用干湿重法测定脑组织的含水量。结果 与对照组相比,治疗组海马 CA1区神经细胞减少(25.7±1.16)%,缺血组减少(31.2±1.49)%;治疗组与缺血组比较有显著性差异(P<0.01)。治疗组脑梗死体积比缺血组明显缩小(P<0.01)。治疗组脑组织含水量比缺血组明显减少(P<0.01)。结论 EPO能够显著降低脑组织含水量,抑制脑水肿,缩小脑梗死体积及减少神经细胞坏死,对脑缺血再灌注损伤有良好的保护作用。
