Mechanisms of hepatic bile secretion were studied in unanesthetized bile fistula rats. After implantation of bile fistula, bile flow and bile acids secretion were significantly decreased and secondary bile acids were greatly decreased. After cholic acid (CA) 30 microM/100 g/hr infusion, bile juice was greatly increased, and CA was dramatically increased in bile. Biliary bile flow and bile acid were not increased after infusion of CDCA 30 microM/100 g/hr. CDCA was slightly increased in bile, but the amount of bile acids tended to decrease. DHCA dramatically increased the amount of bile juice, while DHCA was not detected in the bile. After DHCA infusion, 3 alpha, 7 alpha-dihydroxy-12-keto-5 beta-cholanic acid dramatically increased and slightly increased in CA. Regarding the relationship between the bile flow rate and the secretion rate of the total bile acids, bile acid-dependent bile secretion varied with the bile acid value. On the other hand, Na+ and K+ concentrations of bile were not related to bile acid concentration. These studies show that canalicular bile secretion mechanisms varied with the compositions of bile acids and bile acid secretion rate.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D002635	Chenodeoxycholic Acid	A bile acid, usually conjugated with either glycine or taurine. It acts as a detergent to solubilize fats for intestinal absorption and is reabsorbed by the small intestine. It is used as cholagogue, a choleretic laxative, and to prevent or dissolve gallstones.

D002756	Cholagogues and Choleretics	Gastrointestinal agents that stimulate the flow of bile into the duodenum (cholagogues) or stimulate the production of bile by the liver (choleretic).	Choleretics,Cholagogues,Cholagogues, Choleretics,Choleretics and Cholagogues,Hydrocholeretics
D003685	Dehydrocholic Acid	A semisynthetic bile acid made from cholic acid. It is used as a cholagogue, hydrocholeretic, diuretic, and as a diagnostic aid.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001646	Bile	An emulsifying agent produced in the LIVER and secreted into the DUODENUM. Its composition includes BILE ACIDS AND SALTS; CHOLESTEROL; and ELECTROLYTES. It aids DIGESTION of fats in the duodenum.	Biliary Sludge,Sludge, Biliary
D001647	Bile Acids and Salts	Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones.	Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
