本实验旨在确定去前庭器官是否能防止或破坏毒物引起的催吐反应。用7只正常雄性杂种狗,每周进行一次摆动试验,接连4次,确定它们对运动病的易感性。完成试验数周后,再给这些动物肌注催吐毒物以试验其催吐反应。这些毒物是:盐酸毛果芸香硷(0.6mg/kg),盐酸洛贝林(2mg/kg),左旋多巴(1,2,3号狗1mg/kg;4, The purpose of this experiment was to determine if the vestibular organ could prevent or destroy the toxic effects of the emetic response. Seven normal male mongrel dogs were challenged once a week for 4 consecutive times to determine their susceptibility to motion sickness. A few weeks after completing the test, these animals were given intramuscular emetic to test their emetic response. These poisons are: pilocarpine hydrochloride (0.6 mg / kg), lobeline hydrochloride (2 mg / kg), levodopa (dogs 1, 2, 3 mg / kg;
