| bile acid 7 alpha-dehydroxylase | <enzyme> Mechanism is questionable: cholic acid - deoxycholic acid - chenodeoxycholic acid - lithocholic acid Registry number: EC 1.14.- Synonym: 7 alpha-dehydroxylase, bile acid 7-dehydroxylase, bile acid 7-alpha-dehydroxylase, bai a1, bai a2, bai a3, cholic acid 7alpha-dehydroxylase (26 Jun 1999) |

| bile acid-CoA ligase | <enzyme> Catalyses the synthesis of all bile acid-coas; in order to measure the activity of all bile acids, the bile acid is coupled with c(14)-glycine and measured with bile acid-CoA glycine-taurine n-acetyltransferase Registry number: EC 6.2.1.- (26 Jun 1999) |
| bile acids | Steroid acids found in bile; e.g., taurocholic and glycocholic acid's, used when biliary secretion is inadequate and for biliary colic. Their physiological roles include fat emulsification. Their synthesis is reduced in disorders of the peroxisomes. (05 Mar 2000) |
| bile acids and salts | <chemical> 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. Pharmacological action: cholagogues and choleretics, gastrointestinal agents. (12 Dec 1998) |
| bile acid tolerance test | A sensitive test of hepatic dysfunction; following oral administration of labelled or unlabelled bile acid, the measured fractional disappearance rate or 10-minute retention is measured. (05 Mar 2000) |
| bile alcohol | One of a group of polyhydroxylated alcohols derived from cholestane. (05 Mar 2000) |
| bile canaliculi | Minute intercellular channels that occur between liver cells and carry bile towards interlobar bile ducts. Also called bile capillaries. (12 Dec 1998) |
| bile capillary | One of the intercellular channels, about 1 um or less in diameter, that occurs between liver cells forming the first portion of the bile system. Synonym: bile capillary. (05 Mar 2000) |
| bile cyst | <anatomy> A digestive organ which stores bile (produced in the liver), used in the digestion and absorption of fats in the duodenum. (27 Sep 1997) |
| bile ducts, extrahepatic | Passages external to the liver for the conveyance of bile. These include the common bile duct and the common hepatic duct (hepatic duct, common). (12 Dec 1998) |
| bile ducts, intrahepatic | Passages within the liver for the conveyance of bile. Includes right and left hepatic ducts even though these may join outside the liver to form the common hepatic duct. (12 Dec 1998) |
| bile esculin test | A biochemical test used in characterizing group O streptococci, based on the ability of organisms to grow in a medium containing bile and to hydrolyze esculin. (05 Mar 2000) |
| bile gastritis | An inflammation of the gastric mucosa believed to be caused by irritating factors in bile. Synonym: alkaline reflux gastritis. (05 Mar 2000) |
| bile nephrosis | <gastroenterology, nephrology> Acute renal failure occurring in a patient with liver failure. The exact causal relationship in unclear, but those with alcoholic cirrhosis and alcoholic hepatitis are at greatest risk. Symptoms include decreased or absent urine production, jaundice, abdominal swelling, delirium, confusion, nausea and vomiting. Prognosis is very poor. (27 Sep 1997) |
| bile papilla | Point of opening of the common bile duct and pancreatic duct into the duodenum; it is located posteriorly in the descending part of the duodenum. Synonym: papilla duodeni major, bile papilla, papilla of Vater, Santorini's major caruncle. (05 Mar 2000) |
