The influence of bile acids on biliary excretion of indocyanine green in rats of different ages. 1981

A Barth, and Z Gregus, and W Klinger, and F Varga

In rats of different ages bile flow and biliary excretion of indocyanine green (ICG) were estimated in dependence on bile acid excretion. In 20, 30, 60 and 180 day old rats bile acid excretion was diminished to a quarter of the control by pretreatment with cholestyramine (1.5 g/kg b.wt.). To enhance bile acid excretion, taurocholate sodium (TC, 50 mg/kg b.wt.) was given together with the dye. Bile acid depletion diminished the bile flow to a greater extent in young rats, which were found to have a higher bile acid dependent fraction of canalicular bile flow (60%) compared to 60 (35%) and 180 day old rats (20%). After bile acid depletion the decrease in ICG excretion was more pronounced in 30 and 60 day old rats which exhibit highest dye excretion rates. TC was able to enhance the bile flow in all age groups investigated, however, the ICG excretion was enhanced only in adult animals. Our results indicate that the bile acid dependence of the hepatobiliary transport of ICG is influenced by age.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

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
D001652	Bile Ducts	The channels that collect and transport the bile secretion from the BILE CANALICULI, the smallest branch of the BILIARY TRACT in the LIVER, through the bile ductules, the bile ducts out the liver, and to the GALLBLADDER for storage.	Bile Duct,Duct, Bile,Ducts, Bile
D013656	Taurocholic Acid	The product of conjugation of cholic acid with taurine. Its sodium salt is the chief ingredient of the bile of carnivorous animals. It acts as a detergent to solubilize fats for absorption and is itself absorbed. It is used as a cholagogue and cholerectic.
