[Abstract]  The alcohol preference model is one of the most widely used animal models relevant to alcoholism. Stressors increase alcohol consumption. Here we present a protocol for a rapid and useful tool to test alcohol preference and stress-induced alcohol consumption in mice. In this model, animals are given two bottles, one with a diluted solution of ethanol in water, and the other with tap water. Consumption from each bottle is monitored over a 24-h period over several days to assess the animal’s relative preference for the ethanol solution over water. In the second phase, animals are stressed by restraining them for an hour daily and their subsequent preference of tap water or the ethanol solution is evaluated. Preference is measured by the volume and/or weight or liquid consumed daily, which ... [摘要]  酒精偏好模型是与酒精中毒相关的最广泛使用的动物模型之一。压力源增加酒精消耗。在这里,我们提出了一个快速和有用的工具协议,以测试小鼠的酒精偏好和压力诱导的酒精消费。在该模型中,给动物两瓶,一瓶用乙醇在水中稀释的溶液,另一瓶用自来水。在几天内监测每瓶的消耗24小时,以评估动物对乙醇溶液相对于水的相对偏好。在第二阶段,通过每天约束它们一小时来对动物施加压力,并评估它们随后对自来水或乙醇溶液的偏好。优选通过每日消耗的体积和/或重量或液体来测量,然后将其转换为优选比率。将酒精偏好模型与条件性位置偏好范例相结合,以确定DAT- Cnr2 > Cre重组条件性敲除(cKO)小鼠中多巴胺能神经元中CB2大麻素受体缺失后的酒精调节和偏好。与野生型对照小鼠比较。

【背景】可以通过动物模型研究酒精中毒和饮酒的许多方面。酒精诱导积极的强化,动物可以寻求酒精,甚至为它工作。然而,酒精也可以是负面强化,因为它能够减少焦虑。没有动物模型能够复制酗酒的复杂特征。口服乙醇自我施用被广泛用于检查与理解酒精中毒相关的行为和生理学的特定方面(Mardones和Segovia-Riquelme,1983; Cunningham 等人,>,2000)。小鼠可以在细胞类型特异性水平上进行遗传操作,因此对于研究酒精中毒的细胞类型特异性遗传决定因素是有价值的。

酒精偏好模型是与酒精中毒相关的最广泛使用的动物模型之一。该模型符合重要标准,即乙醇应自口服(Cicero,1980; ...
