FASCICULATION CAUSED BY SUXAMETHONIUM AND OTHER CHOLINERGIC AGENTS

Acta Neurologica Scandinavica, 1971
Fasciculation caused by suxamethonium has been investigated in Man and early observations on fasciculation caused by other cholinergic agents have been reviewed. The body of evidence suggests that these agents cause fasciculation by an action on some distal part of motor nerve fibres.

In vitro and in vivo modulation of cholinergic muscarinic receptors in rat lymphocytes and brain by cholinergic agents

International Journal of Immunopharmacology, 1990
A binding site for 3H-quinuclidinyl benzylate (QNB) has been identified in rat lymphocytes which has the characteristics of a cholinergic muscarinic receptor (Costa, L. G., Kaylor, G. & Murphy, S. D. (1988). Muscarinic cholinergic binding sites on rat lymphocytes.

Cholinergic Agents and the Mccollough Effect

Perception, 2000
The strength of the McCollough effect (ME), a pattern-contingent colour aftereffect, has been shown to be inversely related to acetylcholine, being significantly strengthened by (anti-cholinergic) scopolamine and weakened by (cholinergic) physostigmine delivered before adapting to the ME stimuli.

Effects of cholinergic agents on anorectal physiology

Alimentary Pharmacology & Therapeutics, 1998
Background:Despite their potential therapeutic benefit, the effects of cholinergic agents on anal function have been poorly investigated.Aim:To analyse the effects of neostigmine and atropine on anorectal responses to rectal isobaric distension.Methods:This was a placebo‐controlled, randomized, double‐blind crossover study, performed in 12 healthy ...

Quasi-Cholinergic Action of Acetylating Agents

Nature, 1962
THE process by which acetylcholine causes muscle to contract presumably includes an action of acetylcholine on a definite site. The exact nature of this site, whether it is a small molecule, or a protein or enzyme, or a membrane, is still unknown. Although it is still inexactly defined, this substance or structure has acquired the presumably synonymous

Noradrenergic and Cholinergic Agents in Korsakoffʼs Syndrome

Clinical Neuropharmacology, 1986
Subjects suffering from memory disorders associated with Korsakoff's syndrome were treated with noradrenergic and cholinergic drugs in two phases. In the acute phase, tests of short- and long-term memory were conducted shortly after the administration of methylphenidate, physostigmine, an oral placebo, and an intramuscular placebo. In the chronic phase,

Cholinergic agents and delay-dependent performance in the rat

Pharmacology Biochemistry and Behavior, 1994
We tested cholinergic agents in delayed matching and nonmatching to position. Each task had a delay between the presentation of information and the chance to act on it later. We used a titrating procedure, new to experiments with rats, to determine the delay.

Plasma cyclic GMP: Response to cholinergic agents

European Journal of Pharmacology, 1978
S.c. injections of cholinergic agents, carbachol, methacholine and bethanechol, into fasted rats caused rapid increases in the plasma concentration of cyclic GMP, with a sharp peak at 5--10 min after the injection. Acetylcholine gave rise to a rapid accumulation of cyclic GMP in plasma only when administered together with physostigmine which produced ...

Cholinergic and GABAergic neurotoxicity of some alkylating agents

Biochemical Pharmacology, 1986
A series of nitrogen mustard derivatives was tested for neurotoxic effects on cholinergic and GABAergic markers at three rat brain regions: hippocampus, striatum and cortex. All compounds were administered intracerebroventricularly, and the enzymatic activities were measured 7 days after treatment.

Effect of cholinergic agents on human spermatozoa motility

Biochemical Medicine and Metabolic Biology, 1989
The effect of various cholinergic agents on human spermatozoa motility was studied. Both direct-acting (e.g., acetylcholine, pilocarpine) and indirect-acting (e.g., physostigmine) cholinergic agonists stimulated human spermatozoa motility. All the cholinergic antagonists (e.g., atropine, hyoscine, hexamethonium, d-tubocurarine, and succinylcholine ...
