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:32只SD大鼠,采用夹闭双侧颈总动脉30min再灌注24h制作脑缺血/再灌注模型。随机分为4组(n=8):假手术组、脑缺血/再灌注组、Epo组及阳性对照组(尼莫地平),观察缺血/再灌注后血清一氧化氮(NO)和脑组织匀浆中超氧化歧化酶(SOD)活性、丙二醛(MDA)含量及脑组织含水量的变化。结果:Epo组血清NO和脑组织匀浆中MDA含量显著下降,SOD活性显著升高,脑组织含水量显著下降,与缺血/再灌注组相比有显著性差异。结论:大鼠脑缺血/再灌注后,Epo能减轻脑组织的含水量,减少自由基的生成,减轻脂质过氧化反应,对脑缺血/再灌注损伤有保护作用。
