An inhibition of post‐ganglionic motor transmission in the mammalian vas deferens by D‐lysergic acid diethylamide

Abstract
1. Under certain conditions D-lysergic acid diethylamide (LSD), 10-9-10-6 g/ml., exerted an immediate, prolonged and slowly reversible inhibitory effect upon the post-ganglionic motor transmission in desheathed guinea-pig vas deferens preparations.
