摘要: 目的:探讨盐酸多奈哌齐(DPH)对正常成年大鼠学习、记忆功能的影响。方法:采用区组随机分组方法按体重随机将Wistar大鼠分为正常对照组及DPH(n=20),DPH组灌胃给DPH 0.85 mg•kg-1•d-1,正常对照组灌胃同体积的生理盐水,连续给药10 d后,采用Morris水迷宫、跳台行为学实验方法,观察DPH对正常成年大鼠学习、记忆功能的影响。结果:DPH大鼠给药第1~6天达到平台的潜伏期、游程、平均速度、朝向角及第7天大鼠在2 min内的穿越平台的次数、在平台区的逗留时间、平台象限内的逗留时间、平均速度、朝向角及平台区象限内的游程占总游程的百分比,与正常对照组比较差异均无显著性(P>0.05);DPH组大鼠第1和2天跳台的错误次数及潜伏期,与正常对照组比较差异均无显著性(P>0.05)。结论:DPH对正常成年大鼠学习、记忆功能无促进作用。

Abstract: To explore the effects of donepezil hydrochloride on learning and memory function in normal adult rats. Methods According to weight,40 Wistar rats were randomly divided into 2 groups: normal control group and donepezil hydrochloride group(n=20).The learning and memory function in rats were determined with Morris water maze and Step-down tests.Results Compared with control group,latency,distance,average speed and starting angle of rats treated by donepezil hydrochloride did not change significantly from the first day to the sixth day (P>0.05);the time in platform, the time of platform quadrant in 2 minutes,times passing platform, the percentage of distance in platform / total distance and average speed also did not change significantly on the 7th day in Morris water maze test(P>0.05) ; Error times of rats treated by donepezil hydrochloride did not decrease on the 1st and 2nd day(P>0.05),latency did not prolong in the 2nd day in Step-down test(P>0.05) Conclusion Donepezil hydrochloride do not improve learning and memory function in normal adult rats.
