摘要 目的 研究银杏叶提取物EGb761对实验性变态反应性脑脊髓炎(EAE)大鼠的神经行为学及脑脊髓组织病理改变.以探讨EGb761对脱髓鞘疾病的神经保护及髓鞘再生的作用.方法 将Wistar大鼠随机分为3组,正常对照(NC)组,EAE组,BGb761组.诱导Wistar大鼠BAE模型,同时以EGb761分别于免疫当日开始治疗,并观察神经行为改变;全部动物于免疫第14d取脑,脊髓,常规病理切片,HE染色.结果 与EAE组相比,EGb761组推迟了EAE发病时间,其临床评分在疾病高峰时有明显下降.BGb761组较EAE组,脑和脊髓炎性细胞浸润,神经元肿胀、变性、坏死明显减轻.正常对照组未见异常.结论 EGb761使EAE大鼠减轻了脱髓鞘症状,减轻组织中神经髓鞘及神经元的损伤,对神经有保护作用,并促进神经髓鞘的再生.
