| encysted calculus | A urinary calculus enclosed in a sac developed from the wall of the bladder. Synonym: pocketed calculus. (05 Mar 2000) |
| jackstone bladder calculus | <radiology> Spiculated calculus in urinary bladder, calcium oxalate monohydrate (12 Dec 1998) |
| urethral calculus | A stone impacted in urethra. May have formed proximally and gotten stuck there or may have formed in urethra; uncommon. (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) |
