| sulfur mustard | <chemical> 1,1'-thiobis(2-chloroethane). Severe irritant and vesicant of skin, eyes, and lungs. It may cause blindness and lethal lung oedema and was formerly used as a war gas. The substance has been proposed as a cytostatic and for treatment of psoriasis. It has been listed as a known carcinogen in the fourth annual report on carcinogens (ntp-85-002, 1985) (merck, 11th ed). Pharmacological action: carcinogens, chemical warfare agents, dermatologic agents. Chemical name: Ethane, 1,1'-thiobis(2-chloro- (12 Dec 1998) |

| quinacrine mustard | <chemical> 2-methoxy-6-chloro-9-[4-bis(beta-chloroethyl)amino-1-methylbutylamino]acridine. Nitrogen mustard analog of quinacrine used primarily as a stain in the studies of chromosomes and chromatin. Fluoresces by reaction with nucleic acids in chromosomes. Pharmacological action: fluorescent dyes. Chemical name: 1,4-Pentanediamine, N1,N1-bis(2-chloroethyl)-N4-(6-chloro-2-methoxy-9-acridinyl)-, dihydrochloride (12 Dec 1998) |
| expressed mustard oil | The fixed oil expressed from the seeds of Brassica alba and B. Nigra; it contains the glycerides of oleic, arachidic, and other fatty acids; used as salad oil and in the manufacture of oleomargarine. (05 Mar 2000) |
| uracil mustard | <chemical> Nitrogen mustard derivative of uracil. It is a alkylating antineoplastic agent that is used in lymphatic malignancies, and causes mainly gastrointestinal and bone marrow damage. Pharmacological action: antineoplastic agent, alkylating. Chemical name: 2,4(1H,3H)-Pyrimidinedione, 5-(bis(2-chloroethyl)amino)- (12 Dec 1998) |
| alveolar gas | The gas in the pulmonary alveoli, where O2-CO2 exchange with pulmonary capillary blood occurs. Synonym: alveolar air. (05 Mar 2000) |
| alveolar gas equation | The equation defining the steady state relation of the alveolar oxygen pressure to the barometric pressure, inspired gas composition, alveolar carbon dioxide pressure, and respiratory exchange ratio; the equation is used in various forms depending upon which simplifying assumptions are acceptable for different applications. (05 Mar 2000) |
| anaesthetic gas | A gas or a liquid with sufficient vapor pressure to produce general anaesthesia when breathed. (05 Mar 2000) |
| arterial blood gas | A test which analyses arterial blood for oxygen, carbon dioxide and bicarbonate content in addition to blood pH. Used to test the effectiveness of respiration. Acronym: ABG (17 Oct 1997) |
| bivalent gas gangrene antitoxin | Antitoxin specific for the toxins of Clostridium perfringens and C. Septicum. (05 Mar 2000) |
| blood gas analysis | <investigation> A test which analyses arterial blood for oxygen, carbon dioxide and bicarbonate content in addition to blood pH. Used to test the effectiveness of respiration. (27 Sep 1997) |
| blood gas monitoring, transcutaneous | The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced haemoglobin. (12 Dec 1998) |
| carbonic acid gas | <biochemistry, physiology> A metabolic byproduct of carbohydrate metabolism. Carbon Dioxide collects in the tissues, is cleared by the blood (via the veins) and removed from the body via the lungs when we exhale air. Abbreviation: CO2 (13 Nov 1997) |
| gas | Origin: Invented by the chemist Van Helmont of Brussels, who died in 1644. 1. An aeriform fluid; a term used at first by chemists as synonymous with air, but since restricted to fluids supposed to be permanently elastic, as oxygen, hydrogen, etc, in distinction from vapors, as steam, which become liquid on a reduction of temperature. In present usage, since all of the supposed permanent gases have been liquified by cold and pressure, the term has resumed nearly its original signification, and is applied to any substance in the elastic or aeriform state. 2. A complex mixture of gases, of which the most important constituents are marsh gas, olefiant gas, and hydrogen, artificially produced by the destructive distillation of gas coal, or sometimes of peat, wood, oil, resin, etc. It gives a brilliant light when burned, and is the common gas used for illuminating purposes. Laughing gas. Any irrespirable aeriform fluid. Gas is often used adjectively or in combination; as, gas fitter or gasfitter; gas meter or gas-meter, etc. <chemistry> Air gas, a kind of gas made by forcing air through some volatile hydrocarbon, as the lighter petroleums. The air is so saturated with combustible vapor as to be a convenient illuminating and heating agent. <physics> Gas battery, a kind of gas made by forcing steam over glowing coals, whereby there results a mixture of hydrogen and carbon monoxide. This gives a gas of intense heating power, but destitute of light-giving properties, and which is charged by passing through some volatile hydrocarbon, as gasoline.

| gas abscess | An abscess containing gas caused by Enterobacter aerogenes, Escherichia coli, or other gas-forming microorganisms. (05 Mar 2000) |
| gas bacillus | The most common aetiologic agent of gas gangrene. It is differentiable into several distinct types based on the distribution of twelve different toxins. (12 Dec 1998) |
