Abstract
  1. Rats were injected with 0.8 mg nicotine/kg, 0.8 mg amphetamine/kg or with saline immediately before being tested for 30 min in activity boxes.2. During the first 3 trials the nicotine group were less active than the controls but from trial 5 onwards nicotine had a stimulant effect. The stimulant effect of the amphetamine did not alter with repeated injection.
摘要
  1. 在将大鼠放入活动箱进行30分钟测试之前,立即给它们注射0.8毫克/千克尼古丁、0.8毫克/千克苯丙胺或生理盐水。

  2. 在最初的3次试验中,尼古丁组的活动量低于对照组,但从第5次试验开始,尼古丁产生了刺激作用。苯丙胺的刺激作用不会因重复注射而改变。
