Biliary secretion in conscious rabbits: role of the enterohepatic circulation of bile salts and of the gall bladder. 1981

A Esteller, and R Jiminez, and M A Lopez

The role of enterohepatic circulation of bile salts in biliary secretion in conscious rabbits has been investigated before and after cholecystectomy. Bile flow was higher and bile salt concentration lower in cholecystectomized than in intact rabbits: this could have been caused by a negative feed-back effect on bile salt synthesis as the circulating bile salt pool increased. The effects of cholecystectomy on flow and bile salt concentration balanced each other. Bile flow and bile salt concentration declined after interruption of the enterohepatic circulation in both cholecystectomized and intact rabbits. Furthermore, the percentage of the flow of bile independent of bile salt secretion increased, while that independent of total analysed solutes decreased after the enterohepatic circulation was broken. These results confirm that the decrease in bile flow after interruption of the enterohepatic circulation is due to loss of bile salts and not of electrolytes.

D005704 Gallbladder A storage reservoir for BILE secretion. Gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the CYSTIC DUCT to the DUODENUM, for degradation of dietary lipid. Gallbladders
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.

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
