| gastric varices | <radiology> Usually associated with oesophageal varices (due to portal hypertension), if WITHOUT oesophageal varices most likely to be consider splenic vein thrombosis due to: pancreatitis / panc carcinoma, increased clotting tendency (polycythemia, etc.) Differential diagnosis: thick gastric folds (12 Dec 1998) |

| gastric vertigo | Vertigo symptomatic of disease of the stomach. Synonym: Trousseau's syndrome. (05 Mar 2000) |
| gastric volvulus | <radiology> Mesenteroaxial, antrum lies above cardia (i.e., rotation around line connecting greater and lesser curvature), form seen in neonates, obstruction at pylorus or GE junction, usually acute, associated with eventration of left hemidiaphragm or diaphragmatic hernia, organoaxial, rare in kids, associated with large hiatus hernia, rotation along long axis of stomach may be asymptomatic if no outlet obstruction or vascular compromise (12 Dec 1998) |
| gastricsin | Former term for a human peptidase now termed pepsin C. (05 Mar 2000) |
| gastricus | Synonym: gastric. Origin: L. (05 Mar 2000) |
| gastriloquist | One who appears to speak from his stomach; a ventriloquist. Origin: Gr. Gasthr, gastros, stomach + L. Loqui to speak. Source: Websters Dictionary (01 Mar 1998) |

| gastrin | <hormone, protein> A group of peptide hormones secreted by the mucosal gut lining of some mammals in response to mechanical stress or high pH. When there is food in the stomach, these cells secrete gastrin. Gastrin then stimulates the stomach parietal cells to produce hydrochloric acid. Normally, as stomach pH lowers, gastrin secretion decreases. Gastrin blood levels can be determined to be elevated in conditions such as Zollinger-Ellison syndrome and pernicious anaemia. Several different gastrins have been identified, human gastrin I has 16 amino acids (2116 D). Gastrin is competitively inhibited by cholecystokinin. (05 Jan 1998) |
| gastrin-releasing peptide | <hormone> A regulatory peptide (27 amino acids) thought to be the mammalian equivalent of bombesin. It elicits gastrin release and regulates gastric acid secretion and motor function. It causes bronchoconstriction and vasodilation in the respiratory tract and stimulates the growth and mitogenesis of cells in culture. Once released from nerves in the antrum of the stomach, the neuropeptide stimulates release of gastrin from the g cells. Chemical name: Gastrin-releasing peptide (12 Dec 1998) |
| gastrinase | <enzyme> Highly specific for the 34 amino acid gastrin Registry number: EC 3.4.99.- Synonym: gastrin-34 protease, gastrin-34 degrading enzyme (26 Jun 1999) |
| gastrinoma | <oncology, tumour> A tumour (gastrinoma) of the pancreatic islet cells that results in an over production of gastric acid, leading to fulminant ulceration of the oesophagus, stomach, duodenum and jejunum. Gastrinomas may also occur in the stomach, duodenum, spleen and regional lymph nodes. Treatment includes the use of H2 antagonists (for example cimetidine, ranitidine). Surgical excision of the tumour is curative in approximately 25% of patients. (27 Sep 1997) |
| gastrins | A family of gastrointestinal peptide hormones that excite the secretion of gastric juices. They may also occur in the central nervous system where they are presumed to be neurotransmitters. (12 Dec 1998) |
| gastritis | <pathology> Inflammation of the stomach. (18 Nov 1997) |
| gastritis cystica polyposa | Large sessile mucosal polyps arising in the stomach proximal to an old gastroenterostomy. (05 Mar 2000) |
