Abstract

Intracellular recordings were made from identified central neurones of the snail Helix aspersa. The antagonism of acetylcholine excitatory and inhibitory responses by d-tubocurarine, HS818 and HS626 was investigated. d-Tubocurarine was equipotent against both the inhibitory and excitatory responses, while HS626 and HS818 were of similar potency to d-tubocurarine in antagonising acetylcholine excitation but were approximately one order of magnitude less potent in antagonising the inhibitory response.

摘要

从鉴定出的蜗牛(即盖罩大蜗牛)中枢神经元进行细胞内记录。研究了d -筒箭毒碱、HS818和HS626对乙酰胆碱兴奋和抑制反应的拮抗作用。d -筒箭毒碱对抑制和兴奋反应的效力相同,而HS626和HS818在拮抗乙酰胆碱兴奋方面与d -筒箭毒碱效力相似,但在拮抗抑制反应方面效力约低一个数量级。
