abstract：:The influence of bile acids on adenosine 3',5'-phosphate-induced intestinal secretion was studied in mice. Bile flow was stopped by ligation of the common bile duct, and secretion was induced in ligated loops of the small intestine. The decrease of bile led to inhibition of hypersecretion after challenge with heat-lab...
