THE EFFECT OF BILE ON THE PROPULSIVE MOTILITY OF THIRY-VELLA LOOPS IN DOGS

Abstract

The rate of propulsion of a sponge rubber pellet through Thiry-Vella loops was markedly increased immediately following the introduction of dog''s gall bladder bile into the loop. A similar response followed the introduction of bile salt soln. Other normal constituents of bile were found to be without significant effect on propulsion. An expt., typical for those using either bile or bile salt soln., yielded normal propulsion rates of 7, 7, and 8 min. as compared with rates of 2.5, 3, and 3.5 min. after the introduction of the soln.
