摘要
本项工作采用大鼠自由饮用药液的给药方法,比较研究了酒精和国产镇痛药强痛定(AP-237)致依赖性特性的相互作用,对强痛定与酒精之间可能存在的依赖性方面相互强化关系进行了初步探讨。实验分为三部分,首先建立人鼠自由饮川药液形成对酒精和强痛定的依赖性模型,而后通过动物对饮液的选择评价其精神依赖性,最后以自然戒断方式评价其身体依赖性。通过对实验结果的分析可以得到下述结论:1.用本实验程序可以使人鼠在35 d内对酒精或强痛定产生精神依赖性和身体依赖性。前者表现为在同时存在药液和水的条件下,大鼠表现出不同程度的觅药行为;后者表现为断药后人鼠所出现的不同类型戒断症状。2.与强痛定或酒精分别单独川药相比,二药同时应用时,可以明显地增强精神依赖性潜力。3.强痛定对酒精的身体依赖性无明显增强或减弱作用。而酒精对强痛定的身体依赖性潜力,则有明显增强作用。本项研究的结果为对人群中可能出现的这两者合并滥用问题进行前瞻性研究提供了实验的依据。
An experimental model of drug dependence in rats by free drin- king of drug solutions was established and used for studying the interactions between dependence-producing properties of alcohol and Qiang Tong Ding (AP-237). Results showed that: (1)both physical and psychic dependence on alcohol and AP-237 appeared in rats after 35 days of drug administration; (2)psychic depen- dence potential on the combination of alcohol with AP-237 was higher than that on alcohol or AP-237 when used separately; (3) AP-237 did not influence the phy- sical dependence on alcohol, but the former's physical dependence potential was enhanced significantly by concomitant use with the latter.
