Abstract

1 Nicotine produced conditioned taste aversions in rats which were directly related to the dose of nicotine and to the number of conditioning trials. 2 The tobacco alkaloid (-)-nicotine was four to five times as potent as its stereoisomer, (+)-nicotine. 3 Mecamylamine but not hexamethonium blocked the development of taste aversions produced by nicotine. 4 Mecamylamine did not block the development of taste aversions produced by apomorphine. 5 Prolonged treatment with mecamylamine prior to conditioning did not produce supersensitivity to nicotine.

摘要
  1. 尼古丁会使大鼠产生条件性味觉厌恶,这与尼古丁的剂量以及条件反射试验的次数直接相关。2. 烟草生物碱(-)-尼古丁的效力是其立体异构体(+)-尼古丁的四到五倍。3. 美加明而非六甲铵能阻断尼古丁引起的味觉厌恶的形成。4. 美加明不能阻断阿扑吗啡引起的味觉厌恶的形成。5. 在条件反射前用美加明进行长期治疗不会产生对尼古丁的超敏反应。
