| intestinal angina | <surgery> A dull, crampy centralised abdominal pain that occurs 15-30 minutes after a meal. Associated with ischaemic bowel disease. Evaluated with mesenteric arteriography. (27 Sep 1997) |
|---|---|
| intestinal anthrax | A usually fatal form of anthrax marked by chill, high fever, pain in the head, back, and extremities, vomiting, bloody diarrhoea, cardiovascular collapse, and frequently haemorrhages from the mucous membranes and in the skin (petechiae). See: mycosis intestinalis. (05 Mar 2000) |
| intestinal arterial arcades | The series of arterial arches formed in the mesentery by anastomoses between adjacent jejunal and ileal arteries and from which vasa recta arise. The arterial arcades of the ileum are shorter and more complex than those of the jejunum. See: arterial arches of ileum, arterial arches of jejunum. Synonym: intermesenteric arterial anastomosis, Riolan's arc, Riolan's arcades. (05 Mar 2000) |
| intestinal arteries | See: ileal arteries, jejunal arteries. (05 Mar 2000) |
| intestinal atresia | Congenital obliteration of the lumen of the intestine, with the ileum involved in 50% of the cases and the jejunum and duodenum following in frequency. It is the most frequent cause of intestinal obstruction in the newborn infant. Its aetiology may be related to failure of recanalization during early development or to some impairment of blood supply during intrauterine life. (12 Dec 1998) |
| intestinal calcium-binding protein | <protein> Calcium-binding proteins containing the EF hand motif, induced by vitamin D3. (18 Nov 1997) |
| intestinal calculus | A concretion in the bowel, either a coprolith or an enterolith. (05 Mar 2000) |
| intestinal capillariasis | A sprue-like diarrhoeal disease caused by infection with Capillaria philippinensis, large populations of which are built up by internal autoinfection in the intestinal mucosa; characterised by abdominal pain, oedema, diarrhoea, cachexia, hypoproteinaemia, hypotension, cardiac failure, and hyporeflexia; severe infection is often manifested as a fulminating disorder that may be fatal. (05 Mar 2000) |
| intestinal digestion | That part of digestion carried on in the intestine; it affects all the foodstuffs: starches, fats, and proteins. (05 Mar 2000) |
| intestinal diseases, parasitic | Infections of the intestines with a parasite. They are caused most commonly by intestinal nematodes (roundworms) and cestodes (tapeworms). (12 Dec 1998) |
| intestinal emphysema | A condition characterised by the presence of thin-walled, gas-containing cysts in the wall of the intestines. The lesions may be subserosal or submucosal. (12 Dec 1998) |
| intestinal epithelium | <pathology> The endodermally derived epithelium of the intestine varies considerably, but the absorptive epithelium of small intestine is usually implied. The apical surfaces of these cells have microvilli possibly to increase the absorptive surface, but probably also to provide a larger surface area for enzyme activity). The lateral sub apical regions have well developed junctional complexes. (10 Jan 1998) |
| intestinal fistula | Abnormal passage communicating with the intestines. (12 Dec 1998) |
| intestinal flora | <microbiology> The various bacteria that normally live in the intestinal tract. Normal intestinal flora are important to aid in the breakdown of certain foods for absorption. (27 Sep 1997) |
| intestinal gas | 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) |
