摘要：目的 研究局灶性脑缺血再灌注损伤中神经元型NOS(nNOS)在不同脑区的表达。方法 用改良的血管内栓线技术制造大鼠局灶性脑缺血与再灌注模型，应用免疫组织化学技术检测脑组织中nNOS的表达。结果 ① 脑缺血再灌注损伤后，脑组织中nNOS 的表达显著性增强，与正常对照组比较，P<0.05 ；②缺血侧在皮质、CA1区和CA3区的nNOS表达比对照侧显著性增强(P<0.05)。结论 一侧脑缺血再灌注后，也会引起对侧损伤，但缺血侧损伤更为严重。关键词：缺血再灌注；一氧化氮合酶； 大鼠

ABSTRACT:Objective To study the expression of neuron nitric oxide synthase (nNOS) in different brain tissue in rats with focal cerebral ischemia reperfusion injury. Methods Modified intravascular embolism method was employed to make focal ischemia in rats.Immunohistochemical method was used to detect the expression of nNOS in brain. Results ①Compared with the normal group,the expression of nNOS had remarkably enhanced after cerebral ischemia reperfusion(P<0.05)；②The nNOS expression in ischemia side was more obvious than opposite side in cortex ......
