title: Influence of sodium deoxycholate on morphology, net fluid transport and motility in the small intestine of the rat.
abstract: Intestinal fluid secretion and motility were induced by luminal perfusion of rat small intestine with sodium deoxycholate, a dihydroxy bile salt for 1-3 h. Changes in intestinal morphology were studied simultaneously with the changes in fluid transport and motility. The results suggest that the bile salt causes epithelial lesions which may lead to a reduced fluid absorption in the villi, thereby explaining part of the total change in net fluid transport caused by the bile salt. Pyrilamine and indomethacin did not influence the bile salt-induced secretion. Based on earlier studies, it is proposed that the major part of the bile salt-evoked secretion is mediated via activation of intramural nervous reflex(es), which also stimulate the intestinal smooth muscle cells.
