| gas peritonitis | Inflammation of the peritoneum accompanied by an intraperitoneal accumulation of gas. (05 Mar 2000) |
|---|---|
| gas phlegmon | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| gas retinopexy | A retinal detachment repair in which the retina is held in place by an expandable gas. Synonym: pneumatic retinopexy. (05 Mar 2000) |
| gas scavengers | Apparatus for removing exhaled or leaked anaesthetic gases or other volatile agents, thus reducing the exposure of operating room personnel to such agents, as well as preventing the buildup of potentially explosive mixtures in operating rooms or laboratories. (12 Dec 1998) |
| gas shift process | A process in which carbon monoxide and hydrogen react in the presence of a catalyst to form methane and water. (05 Dec 1998) |
| gas thermometer | A thermometer filled with dry air or a gas, the expansion or increased pressure of which indicates the degree of heat; used to measure high temperatures. (05 Mar 2000) |
| gas turbine | (combustion turbine) A turbine that converts the energy of hot compressed gases (produced by burning fuel in compressed air) into mechanical power. Often fired by natural gas or fuel oil. (05 Dec 1998) |
| gas vacuole | A prokaryotic cellular organelle consisting of cylindrical vesicles around 75 x 300nm, often in clusters. The wall of the gas vacuole, which is permeable to gases but not to water, is formed from a monolayer of a single protein. Gas vacuoles are found mainly in planktonic cyanobacteria and their prime function is to make the bacterium buoyant. (18 Nov 1997) |
| gas vesicle | The hollow, cylindrical, gas-filled structure in the gas vacuole. It confers ability for gas vacuole to float. (09 Oct 1997) |
| marsh gas | <chemistry> A light, colourless, gaseous, inflammable hydrocarbon, CH4; marsh gas. See Marsh gas, under Gas. <chemistry> Methane series, a series of saturated hydrocarbons, of which methane is the first member and type, and (because of their general chemical inertness and indifference) called also the paraffin (little affinity) series. The lightest members are gases, as methane, ethane; intermediate members are liquids, as hexane, heptane, etc. (found in benzine, kerosene, etc); while the highest members are white, waxy, or fatty solids, as paraffin proper.

| vesicating gas | A gas, such as mustard gas, which upon contact with the skin causes vesication and sloughing; inhalation may result in bronchopneumonia. (05 Mar 2000) |
| vomiting gas | A gas, such as chloropicrin, that can cause vomiting and gastrointestinal disorders such as colic and diarrhoea. (05 Mar 2000) |
| pentavalent gas gangrene antitoxin | Antitoxin specific for the toxin of one or more species of Clostridium that cause gaseous gangrene and associated toxaemia, especially C. Perfringens C. Novyi, C. Histolyticum, and commercially available preparations are usually polyvalent, i.e., contain antitoxin for two or more species. Synonym: pentavalent gas gangrene antitoxin. (05 Mar 2000) |
| chromatography, gas | Fractionation of a vaporised sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix. (12 Dec 1998) |
| mixed expired gas | <physiology> One or more complete breaths of expired gas coming thoroughly mixed from the dead space and the alveoli. (05 Mar 2000) |
