THE EFFECT OF ANOXIC AND ANEMIC ANOXIA ON THE MOTILITY OF THE SMALL INTESTINE AND THE INFLUENCE OF AN EPINEPHRINE-POTENTIATING-AGENT

Abstract
The role of the parasympathetic and sympathetic divisions of the autonomic nervous system in relation to the propulsive motility (measured by Macht''s technique) of the small intestine was studied in controlled expts. on dogs. The motility was significantly decreased in 11 dogs given cocaine (10 mg./kg.) intramusc. and subjected to an air pressure of 248.8 mm. Hg in a low pressure chamber. It was significantly decreased in 6 dogs given the same dose of cocaine, 6 hrs. after hemorrhage (3% of body wt.). There was no significant change in 10 dogs subjected to a pressure of 294.4 mm. Hg in a low pressure chamber 6 hrs. after hemorrhage (3% of body wt.).
