| extra-anatomic bypass | A vascular bypass that does not conform to the preexisting anatomy. (05 Mar 2000) |
|---|---|
| extracranial-intracranial bypass | A vascular shunt created by the anastomosis of an extracranial vessel to an intracranial vessel, usually, the superficial temporal artery to a cortical branch of the middle cerebral artery. (05 Mar 2000) |
| femoropopliteal bypass | A vascular prosthesis that bypasses an obstruction in the femoral artery; may be synthetic material, autologous tissue, or heterologous tissue. (05 Mar 2000) |
| left heart bypass | Any procedure that shunts blood returning from the pulmonary circulation to the systemic circulation without passing through the left heart. This is utilised during some cardiac surgery and experimentally during severe left heart failure or cardiogenic shock. (05 Mar 2000) |
| anterior intestinal portal | Anterior intestinal portal; the opening of the foregut into the midgut. See: epigastric fossa. Synonym: anterior intestinal portal. (05 Mar 2000) |
| gas, intestinal | The complaint referred to as intestinal gas is a common one and the discomfort can be quite significant. Everyone has gas and eliminates it by burping or passing it through the rectum. In many instances people think they have too much gas when in reality they have normal amounts. most people produce 1 to 3 pints of intestinal gas in 24 hours and pass gas an average of 14 times a day. It is made up primarily of odourless vapors such as carbon dioxide, oxygen, nitrogen, hydrogen, and in some families, methane. The unpleasant odour is due to bacteria in the large intestine that release small amounts of gases containing sulfur. (12 Dec 1998) |
| vasoactive intestinal contractor | Mouse homologue of endothelin 2. (18 Nov 1997) |
| vasoactive intestinal peptide | <gastroenterology, protein> Peptide of 28 amino acids, originally isolated from porcine intestine, but later found in the central nervous system where it acts as a neuropeptide and is released by specific interneurons. May also affect behaviour of cells of the immune system. Acronym: VIP (05 Jan 1998) |
| vasoactive intestinal polypeptide | A polypeptide hormone secreted most commonly by non-beta islet cell tumours of the pancreas, producing copious watery diarrhoea and faecal electrolyte loss, particularly hypokalaemia; VIP increases the rates of glycogenolysis; stimulates pancreatic bicarbonate secretion. Synonym: vasoactive intestinal peptide. (05 Mar 2000) |
| receptors, vasoactive intestinal peptide | Cell surface proteins that bind vasoactive intestinal peptide (vip) with high affinity and trigger intracellular changes which influence the behaviour of cells. (12 Dec 1998) |
| megacystitis-microcolon-intestinal hypoperistalsis syndrome | <syndrome> A rare condition characterised by abdominal distention, lax abdominal musculature, incomplete intestinal rotation, and deficient intestinal peristalsis. A large bladder and often vesicoureteral reflux are seen. Typically affects female neonates and usually fatal in first year of life. (05 Mar 2000) |
| multiple intestinal polyposis | Begins usually in late childhood; polyps increase in numbers, causing symptoms of chronic colitis, and carcinoma of the colon almost invariably develops in untreated cases; autosomal dominant inheritance. In the Gardner syndrome there are extracolonic changes (desmoid tumours, etc.). Synonym: polyposis coli. Hamartomatous polyposis of the small or large intestine, Peutz-Jeghers syndrome with melanin spots on the lips, less common, miscellaneous, rare, and doubtful occurrences. Synonym: familial intestinal polyposis. (05 Mar 2000) |
| posterior intestinal portal | In young embryos, the communications from the midgut to the hindgut. (05 Mar 2000) |
| src-related intestinal kinase | <enzyme> An intracellular epithelial cell tyrosine kinase; shares 80% homology with human tyrosine kinase brk; has 451 amino acid residues; amino acid sequence given in first source Registry number: EC 2.7.1.- Synonym: sik protein, sik gene product (26 Jun 1999) |
| neuronal intestinal dysplasia | Increased numbers of ganglion cells with myenteric plexus hyperplasia and increased acetylcholinesterase activity in nerves of the mucosa and submucosa. Clinically, neuronal hyperplasia mimics Hirschprung's disease. Similar findings are seen in patients with multiple endocrine neoplasia syndrome, type IIB, and in neurofibromatosis. Synonym: hyperganglionosis, neuronal intestinal dysplasia. (05 Mar 2000) |
