摘要
目的 研究外源性雌激素替代对大鼠局灶性脑缺血 再灌注损伤的神经保护作用。方法 将12 0只大鼠分为对照组、双侧卵巢切除 (OVX)组、OVX +雌二醇 (E2 )组 (E2 2 0 0 μg/kg ,皮下注射每周 1次 ,连续 4周 )。 4周后用线栓法建立脑缺血再灌注模型 ,在缺血再灌注不同时间观察大鼠脑梗死体积、病理改变、凋亡细胞数及检测血浆雌激素水平。结果 缺血再灌注不同时间均以OVX +E2 组脑梗死体积最小 ,OVX组最大 ,两组比较有显著差异 (均P <0 0 1)。凋亡细胞数OVX组明显多于OVX +E2 组 (P <0 0 5 )。结论 雌激素对缺血 再灌注后脑损伤具有明显的保护作用
