Keyword:  多发性脑梗死细胞间粘附分子-1一氧化氮合酶大鼠;
Abstract: 目的:观察大鼠多发性脑梗死后脑组织内皮细胞表达细胞间粘附分子-1(ICAM-1)蛋白和一氧化氮合酶(NOS)阳性神经元表达的时程变化.方法:48只健康雄性SD大鼠制成多发性脑梗死模型,梗死后分别于1 h到14 d不同时间点处死并取脑,应用免疫组织化学法和NADPH-d组化法标记脑组织切片ICAM-1蛋白和NOS阳性神经元,设对照组和正常组,各6只大鼠.结果:多发性脑梗死后2 h ICAM-1蛋白表达达到高峰,NOS阳性神经元表达也同样达到高峰.结论:ICAM-1和NOS神经元参与大鼠多发性脑梗死的脑损伤.
