摘要
1目的 研究脑缺血再灌注后生长相关蛋白 - 43(GAP- 43)和突触素 p38表达的变化规律 ,探讨中枢神经损伤后修复的可塑性。 2方法 成年健康雌性 Wistar大鼠 36只 ,随机分为实验组和对照组。采用线栓法建立大脑中动脉缺血再灌注大鼠模型 ,应用免疫组织化学方法观察脑缺血再灌注后 GAP- 43和突触素 p38的表达。 3结果 脑缺血再灌注 6 h后 ,GAP- 43表达逐渐增高 ,第 7天达高峰 ,以后逐渐降低 ,第 2 1天仍有表达。脑缺血再灌注 1d后突触素 p38表达增高 ,第 7天达高峰 ,之后逐渐降低 ,第 2 1天降至对照组水平。4结论 中枢神经系统损伤后 ,神经元具有再生和修复的可塑性 ,GAP- 43和突触素 p38是神经损伤和修复的分子标志物。
