  • Title: Effects of bile salts on bile formation in rabbits.
    Author: Miyasaka K, Kitani K.
    Journal: Life Sci; 1986 Jun 02; 38(22):2053-61. PubMed ID: 3713438.
    Abstract:
    The effects of different species of bile salts: deoxycholate, taurochenodeoxycholate, ursodeoxycholate, glycodeoxycholate, tauroursodeoxycholate, chenodeoxycholate and cholate (DCA, TCDC, UDCA, GDCA, TUDC, CDCA, CA) on bile secretion were examined in anesthetized rabbits using two different infusion routes. When bile salts were infused intravenously, all bile salts (except for TCDC) significantly increased the volume of bile and bile salt excretion, but their respective efficiency for bile formation was different. The concentration of bicarbonate ion in the bile significantly increased during the choleretic periods induced by DCA, UDCA, GDCA and CDCA but remained unchanged with the other bile salts (CA, TCDC, TUDC). In rabbits, where a bile salt solution was infused in the duodenum and then drained from the intestine through an incision in the distal part of duodenum, none of these bile salts affected bile secretion. The effects of intravenously administered bile salts on rabbit bile secretion are different in terms of their choleretic potency and bicarbonate excretion depending on the species of bile salts used. Furthermore, it was concluded that the intraduodenal infusion of UDCA, which was found to stimulate the pancreatic exocrine function, did not affect bile secretion.
