The antagonism of acetylcholine excitatory and inhibitory responses of Helix central neurones, by some neuromuscular blocking drugs. 1985

A J Bokisch, and J Hussain, and R A Palmer, and R J Walker

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.

UI	MeSH Term	Description	Entries
D009466	Neuromuscular Blocking Agents	Drugs that interrupt transmission of nerve impulses at the skeletal neuromuscular junction. They can be of two types, competitive, stabilizing blockers (NEUROMUSCULAR NONDEPOLARIZING AGENTS) or noncompetitive, depolarizing agents (NEUROMUSCULAR DEPOLARIZING AGENTS). Both prevent acetylcholine from triggering the muscle contraction and they are used as anesthesia adjuvants, as relaxants during electroshock, in convulsive states, etc.	Neuromuscular Blocker,Neuromuscular Blocking Agent,Neuromuscular Blockers,Agent, Neuromuscular Blocking,Agents, Neuromuscular Blocking,Blocker, Neuromuscular,Blockers, Neuromuscular,Blocking Agent, Neuromuscular,Blocking Agents, Neuromuscular
D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
