Abstract

Previous studies have shown that providing rats with a non-drug alternative in a choice situation can reduce ethanol taking in rats. There is also evidence that brief experience with non-drug reinforcers can reduce the reinforcing effects of drugs like cocaine, even when those non-drug alternatives are not pitted against the drug in a choice procedure. The goal of the present experiment was to determine whether experience with sucrose - a high value non-drug reinforcer in rats - in a non-choice situation would reduce ethanol's reinforcing effects, as measured within a behavioral economic framework. In a first phase, separate groups of rats worked on fixed-ratio schedules for ethanol, sucrose, or ethanol plus sucrose (during separate components within a session). In a second phase, all rats worked for ethanol and sucrose during alternating components. The introduction of sucrose components in the second phase to the group that previously only had experience with ethanol caused a significant decrease in ethanol self-administration. There was also a significant interaction whereby the effect of phase on the elasticity of demand for ethanol differed between the group that only had ethanol and the group that had ethanol plus sucrose in the first phase. These results indicate that a high value non-drug alternative reinforcer can reduce ethanol's reinforcing effects even when that alternative is not available at the time when ethanol is available. These findings suggest that treatments aiming to increase exposure to non-alcohol sources of reinforcement might be beneficial in reducing alcohol drinking.

摘要

先前的研究表明,在选择情境中为大鼠提供非药物替代物可以减少大鼠对乙醇的摄取。还有证据表明,短暂接触非药物强化物可以减少可卡因等药物的强化作用,即使在选择程序中没有将这些非药物替代物与药物相对比时也是如此。本实验的目的是确定在非选择情境中,经历蔗糖(大鼠中的高值非药物强化物)是否会降低乙醇的强化作用,这是在行为经济学框架内进行衡量的。在第一阶段,不同组的大鼠分别按固定比例的乙醇、蔗糖或乙醇加蔗糖(在一次会话的不同部分)进行工作。在第二阶段,所有大鼠在交替的部分为乙醇和蔗糖工作。在第二阶段向以前仅接触过乙醇的组中引入蔗糖部分,导致乙醇自我给药显著减少。还有一个显著的相互作用,即仅在第一阶段有乙醇的组和有乙醇加蔗糖的组之间,阶段对乙醇需求弹性的影响不同。这些结果表明,即使在乙醇可用时不能获得高值非药物替代强化物,也可以降低乙醇的强化作用。这些发现表明,旨在增加对非酒精强化来源的接触的治疗方法可能有助于减少饮酒。
