Abstract
  1. The influence of (+)-amphetamine, given 1 min after each training session, on the performance of 124 rats in a Lashley III maze was measured every 48 hr.2. The first three injections of the drug significantly improved the learning ability of naive rats.3. With prolonged treatment, (+)-amphetamine strongly impaired the maze performance of these rats.4. The chronic administration of (+)-amphetamine to previously trained rats produced the same adverse effect.5. Amylobarbitone sodium given to previously trained rats 30 min before the training sessions completely blocked the adverse effect of (+)-amphetamine.6. (+)-Amphetamine did not produce impairment of performance when given chronically 30 min before training sessions, to previously trained rats.
摘要
  1. 在每次训练后1分钟给予(+)-苯丙胺,每48小时测量其对124只大鼠在拉什利Ⅲ型迷宫中表现的影响。

  2. 药物的前三次注射显著提高了未受过训练大鼠的学习能力。

  3. 随着治疗时间延长,(+)-苯丙胺严重损害了这些大鼠的迷宫表现。

  4. 对先前受过训练的大鼠长期给予(+)-苯丙胺产生了相同的不良影响。

  5. 在训练前30分钟给先前受过训练的大鼠注射戊巴比妥钠,完全阻断了(+)-苯丙胺的不良影响。

  6. 对先前受过训练的大鼠,在训练前30分钟长期给予(+)-苯丙胺时,并未产生表现受损的情况。
