目的:研究茯苓改善学习记忆及镇静催眠的作用。方法:采用morris水迷宫实验和戊巴比妥钠协同催眠实验分别评价茯苓改善学习记忆与镇静催眠的作用。结果:高剂量与中剂量茯苓水提液能明显缩短苯巴比妥钠模型小鼠2 min内达到终点平台的潜伏期,并且能显著增加苯巴比妥钠模型小鼠在平台所在象限的时间和行程;茯苓高剂量组能明显增加小鼠睡眠时间和小鼠入睡只数,提高入睡率。结论:茯苓能改善苯巴比妥钠所致记忆障碍小鼠的学习记忆能力,也具有明显镇静催眠作用。
Objective ： To study the effects of Poria cocos on improving learning and memory and its sedative and hypnotic effect.
