Abstract

1 The double-blind study on twenty healthy students was an attempt at assessing the effects of 2-week's treatment with amitriptyline (25 mg three times a day) and mianserin (10 mg three times a day), each alone or separatively inbibed with alcohol (0.5 g/kg) on the immediate memory and on the acquisition of a paired-association learning-task. 2 Amitriptyline impaired both the short-term memory-span and acquisition, and alcohol potentiated these effects. The action of mianserin did not deviate significantly from that of the placebo, and it also failed to interact with alcohol. 3 It is concluded that the decrement in learning capacity, that occurs after the 2-week's treatment with therapeutic doses of amitriptyline, reflects changes in both the intrinsic and the regulatory mechanisms of learning.

摘要
  1. 这项针对20名健康学生的双盲研究旨在评估阿米替林(每日三次,每次25毫克)和米安色林(每日三次,每次10毫克)单独使用或分别与酒精(0.5克/千克)同时摄入,对即时记忆和配对联想学习任务获取的影响,为期两周。2. 阿米替林损害了短期记忆广度和学习能力,酒精增强了这些影响。米安色林的作用与安慰剂相比无显著差异,且它也未与酒精发生相互作用。3. 得出的结论是,用治疗剂量的阿米替林进行两周治疗后出现的学习能力下降,反映了学习的内在机制和调节机制的变化。
