| biliary scan | <investigation, radiology> A test that uses a radioactive tracer to look for bile duct obstruction or gallbladder inflammation. A special tracer is injected into a vein that tends to collect primarily in the liver. It is then excreted in the bile where it makes its way to the gallbladder. A gamma camera measures the tracer (radioactivity) and generates an image of the gallbladder and biliary system. (27 Sep 1997) |
|---|---|
| biliary steatorrhoea | Steatorrhoea due to the absence of bile from the intestine; usually accompanied by jaundice. (05 Mar 2000) |
| biliary stricture | <gastroenterology, 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) |
| biliary tract | <anatomy> The biliary tract refers to the bile ducts within the liver, the common bile duct (connecting the liver and gallbladder to the small intestine) and the cystic duct (short duct that connects the common bile duct to the gallbladder). Blockage in any location in the biliary tract can result in obstructive jaundice. (27 Sep 1997) |
| biliary tract surgical procedures | Any surgical procedure performed on the biliary tract. (12 Dec 1998) |
| biliary xanthomatosis | Xanthomatosis with hypercholesterolaemia, resulting from biliary cirrhosis. Synonym: Rayer's disease. (05 Mar 2000) |
| glands of biliary mucosa | Small, mucous, tubuloalveolar glands in the mucosa of the larger bile ducts and especially in the neck of the gallbladder. Synonym: glandulae mucosae biliosae, Luschka's cystic glands, Theile's glands. (05 Mar 2000) |
| primary biliary cirrhosis | <gastroenterology> A rare form of liver disease which results in the irreversible destruction of the liver and bile ducts. The cause is unknown, but is thought to be an autoimmune mechanism. (06 Mar 1998) |
| liver cirrhosis, biliary | Liver cirrhosis in which there is interference with intrahepatic bile flow. It includes primary biliary cirrhosis, an intrahepatic disturbance of bile secretion affecting predominantly middle-aged women and with segmental destruction and, later, absence of septal bile ducts (cirrhosis is the end stage); and secondary biliary cirrhosis, which is produced by prolonged mechanical obstruction of large intrahepatic or extrahepatic bile ducts. (12 Dec 1998) |
| Venezuelan equine encephalomyelitis | A form of mosquito-borne equine encephalomyelitis found in parts of South America, Panama, and Trinidad, caused by the Venezuelan equine encephalomyelitis virus (a species of Alphavirus in the family Togaviridae), and characterised by less central nervous system involvement than occurs in either eastern or western equine encephalomyelitis; fever, diarrhoea, and depression are common; in man, there is fever and severe headache after an incubation period of 2 to 5 days, and in a few cases there has been central nervous system involvement. (05 Mar 2000) |
| Venezuelan equine encephalomyelitis virus | A group A arbovirus of the genus Alphavirus, family Togaviridae, occurring in Venezuela and several other South American countries, in Panama and Trinidad, and occasionally the United States causing Venezuelan equine encephalomyelitis in horses and humans; it seems to be more viscerotropic than neurotropic; the virus is transmitted by Culex mosquitoes. Synonym: VEE virus. (05 Mar 2000) |
| gonadotropins, equine | Polypeptide hormones secreted in pregnant mares at the junction of the placenta and endometrial cups. Preparations of this taken from the blood serum of pregnant mares have been used in the treatment of infertility, pituitary dwarfism, cryptorchidism, and other conditions in both human males and females. (12 Dec 1998) |
| rhinoviruses, equine | A group of viruses of the family picornaviridae, yet unclassified as to genus, though not a member of rhinovirus. They cause a disease in horses characterised by rhinitis, pharyngitis, and fever. (12 Dec 1998) |
| western equine encephalomyelitis | An equine encephalomyelitis found in the western U.S. And parts of South America, transmitted by mosquitoes and caused by the western equine encephalomyelitis virus (a species of Alphavirus in the family Togaviridae); the infection is similar to but milder than eastern equine encephalomyelitis in man and is, as a rule, inapparent, but some cases with central nervous system involvement have been fatal. (05 Mar 2000) |
| western equine encephalomyelitis virus | A group A arbovirus of the genus Alphavirus, family Togaviridae, occurring in the western United States and parts of South America; it occurs naturally, usually as a symptomless infection in birds, but causes western equine encephalomyelitis in horses and humans following transfer by the bites of mosquitoes, chiefly Culex tarsalis. Synonym: WEE virus. (05 Mar 2000) |
