Rats were trained to discriminate between d-amphetamine and saline. The discriminable ED50 values for amphetamine isomers were calculated from dose--response curves and the potency ration was 4.9 Co-administration of the ED50s was shown to produce synergistic effects suggesting that the amphetamine isomers may share a common site of action.
训练大鼠区分右旋苯丙胺和生理盐水。根据剂量-反应曲线计算苯丙胺异构体的可区分半数有效剂量（ED50）值，效价比为4.9。同时给予ED50剂量显示出协同效应，这表明苯丙胺异构体可能具有共同的作用位点。
