摘要 目的:建立甲基苯丙胺(MA)慢性依赖大鼠模型及评价体系。方法:SD大鼠60只,随机分为6组:对照组、2 mg·kg-1MA组、10 mg·kg-1MA组、20 mg·kg-1MA组、30 mg·kg-1MA组、40 mg·kg-1MA组。观察记录实验大鼠给药后刻板行为变化,并检测记录大鼠的体重改变、条件性位置偏爱实验结果。建立MA依赖大鼠模型。结果:根据实验动物给药后行为、体重改变以及是否形成条件性位置偏爱3个方面的指标变化,建立MA依赖大鼠模型和评价指标体系。结论:成功建立了MA慢性依赖大鼠模型和评价指标体系。 Objective:To set up methamphetamine (MA)dependence rat model and assessment system. Methods:Sixty Strague - Dawley rats were randomly assigned into six experimental groups. The experimental groups were administered once daily with saline (control group, n - 10 ) or methamphetamine (ip) 2 rag. kg^-1(n=10), lOmg. kg^-1(n=10), 20mg·kg^-1(n=10),30mg·kg^-1 (n = 10) and 40 mg · kg^-1 (n = 10) in consequent 7 days. The stereotyped behavior, bodyweight changes and conditioned place preference (CPP) were observed to establish methamphetamine dependence model. Results: According to change of weight, the stereotyped behavior and the consequence of CPP, methamphetamine dependent model and assessment system were set up. Conclusion: The methamphetamine dependent model in rats and assessment system has been conducted.
