| 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) |
| immunoproliferative small intestinal disease | A spectrum of conditions ranging from a benign plasma cell hyperplasia to a highly malignant lymphoma of the small intestine. (12 Dec 1998) |
| intestinal | <anatomy> Pertaining to the intestine. Origin: L. Intestinalis (18 Nov 1997) |
| intestinal 15 kD protein | <chemical> From rat ileum; potent lipid-binding protein; mw 15 kD; amino acid sequence given in first source was found to be highly homologous to gastrotropin and rat liver fatty acid-binding proteins; same size transcript also found in ovary; may be involved in metabolism of steroids Synonym: i-15p (05 Dec 1998) |
| intestinal anastomosis | Establishment of a new communication between two segments of intestine. Synonym: enteroanastomosis, intestinal anastomosis. (05 Mar 2000) |
