Abstract
The effects of acetylcholine and substance P were studied on the Frog's olfactory mucosa. Stimulation with these chemicals elicited low-threshold slow electrical potentials. Moreover, prior application of substance P strongly depressed the electrical response of the mucosa to acetylcholine. These results are discussed in relation to the possibility that acetylcholine and substance P could act on the functioning of the olfactory neuroreceptors.
摘要
研究了乙酰胆碱和P物质对青蛙嗅粘膜的作用。用这些化学物质刺激引发了低阈值慢电位。此外，预先应用P物质强烈抑制了粘膜对乙酰胆碱的电反应。结合乙酰胆碱和P物质可能作用于嗅觉神经感受器功能的可能性对这些结果进行了讨论。
