| 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 duct | <anatomy> A duct that carries bile from the liver and gallbladder to the duodenum (first part of the small intestine). (27 Sep 1997) |
| bile duct obstruction, extrahepatic | Impairment of bile flow through the hepatic, cystic, or common bile ducts or vater's ampulla. This is sometimes called surgical jaundice. (12 Dec 1998) |
| bile duct pressure | <radiology> Normal: 15-20 cm H2O (12 Dec 1998) |
| 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 duct stricture | <surgery> An abnormal narrowing of the common bile duct. A potential cause for biliary obstruction. Risk factors are prior surgery, pancreatitis, trauma and gallstones. Symptoms include jaundice, fever, chills and abdominal pain. Endoscopic surgery has been successful in removing strictures of the bile duct. (27 Sep 1997) |
