Intestinal secretion was produced in anesthetized cats and rats by exposing isolated
intestinal segments to cholera enterotoxin. Giving, for example, tetrodotoxin, a nerve-
conduction-blocking agent, or adding lidocaine, a local anesthetic agent, to the solution in
the intestinal segments markedly inhibited the rate of choleraic secretion, and in most
experiments a net absorption of fluid was observed. The results suggest that intramural
nervous mechanisms are involved in the pathogenesis of choleraic secretion.
