Abstract
  1. A method for studying in vivo the process of neuroeffector transmission in the nictitating membrane and nasal blood vessels of the cat is described. 2. Administration of desmethylimipramine or cocaine caused increases in both the amplitude and duration of the nasal and membrane responses which may be explained by inhibition of neuronal uptake of noradrenaline. 3. Phenoxybenzamine depressed the responses to nerve stimulation, but had little effect on the relationship between response amplitude and rate of recovery. 4. The relationship between response amplitude and rate of recovery is discussed and related to the sigmoid shape of a log concentration-response curve.
摘要
  1. 本文描述了一种在猫的瞬膜和鼻血管中体内研究神经效应器传递过程的方法。2. 给予去甲丙咪嗪或可卡因会导致鼻和膜反应的幅度和持续时间增加,这可能是由于去甲肾上腺素的神经元摄取受到抑制所致。3. 酚苄明抑制对神经刺激的反应,但对反应幅度与恢复速率之间的关系影响不大。4. 讨论了反应幅度与恢复速率之间的关系,并将其与对数浓度-反应曲线的S形相关联。
