摘要 目的:左旋多巴(levodopa,L-dopa)是治疗帕金森病的金标准[1]。用L-dopa治疗6-羟基多巴胺诱导的帕金森病模型大鼠,观察大鼠的行为学改变,为进一步完善L-dopa治疗帕金森病提供理论依据。方法:取12只成功建模的SD雄性大鼠随机分成2组(L-dopa组和vehicle对照组),每组6只,L-dopa组和vehicle对照组分别以1、3、5、7、14天腹腔注射L-dopa和生理盐水,观察阿扑吗啡(Apomorphine,APO)诱导的大鼠旋转行为变化。结果:在行为学上,L-dopa组在治疗后2小时,APO诱导的旋转启动时间明显缩短,5天后逐渐延长;随着治疗时间的延长,2实验组旋转圈数有增加的趋势,但治疗前后旋转圈数变化不明显。结论:腹腔注射L-dopa可改善APO诱导的大鼠旋转启动时间。
