X-Ray Signs of Altered Alimentary Function Following Autonomic Blockade with Tetraethylammonium

Abstract

Roentgenologic observations indicated that tetramethylammonium produced diminution of gastrointestinal tone and caused virtually complete cessation of motility in the small bowel. In many instances, movements of the small intestinal mucosal folds were completely stopped for relatively long periods of time. This was in contradistinction to the action of atropine and adrenalin, both of which produced some decrease in motility but neither of which had any appreciable effect on mucosal movements.
