摘要
目的 :观察尿激酶 (UK)静脉溶栓治疗大鼠急性脑梗死的疗效。方法 :制作改良大鼠自体血栓性大脑中动脉闭塞 (MCAO)模型 ,在MCAO后 3 0min静脉注入尿激酶 2 0 0 0 0U·kg-1(A组 )、5 0 0 0 0U·kg-1(B组 ) ,MCAO后 12h通过神经功能缺损评分、梗死体积、血管再通率、出血并发症及病理检查等比较研究不同剂量尿激酶溶栓的疗效。结果 :A、B组MCAO后 12h神经功能缺损评分增加、梗死体积减少均较对照组有显著性差异 (P <0 0 5 ,P <0 0 1) ,B组较A组梗死体积小 (P <0 0 5 ) ,并发出血率 3组无显著差异。结论 :UK溶栓能显著改善脑梗死大鼠的神经功能缺损程度、使血管完全或部分再通、减少梗死体积 ,MCAO后 3 0min溶栓不增加出血性转换的发生率
