| calcium oxide | <chemical> A chemical compound with the formula CaO which is a whitish, odourless solid that does not dissolve well in water. It will, however, react with water (H20) to form calcium hydroxide (CaOH, a base). It has a melting point of 2614 degrees Celsius and a boiling point of 2850 degrees Celsius. It can be made by heating calcium carbonate (CaCO3, limestone) until carbon dioxide (CO2) is released. It has a great many industrial uses. (09 Oct 1997) |

| magnesium oxide | <chemical> Magnesium oxide (mgo). An inorganic compound that occurs in nature as the mineral periclase. In aqueous media combines quickly with water to form magnesium hydroxide. It is used as an antacid and mild laxative and has many nonmedicinal uses. Pharmacological action: antacids, cathartic. Chemical name: Magnesium oxide (MgO) (12 Dec 1998) |
| red oxide of lead | A bright orange-red powder that turns black when heated; used in ointments and plasters. Synonym: red lead, red oxide of lead. (05 Mar 2000) |
| mercuric oxide | The red precipitate of HgO; it has been used externally as an antiseptic in chronic skin diseases and fungus infections. The yellow precipitate of HgO; used externally as an antiseptic in the treatment of inflammatory conditions of the eyelids and the conjunctivae. (05 Mar 2000) |
| polyvinylpyridine n-oxide | <chemical> Poly-2-vinylpyridine-n-oxide. Inhibits the cytotoxic action of quartz and is reported to have delayed the development of experimental silicosis in rats. Chemical name: Pyridine, 2-ethenyl-, 1-oxide, homopolymer (12 Dec 1998) |

| stannic oxide | SnO2;used in industry; it is a cause of pneumoconiosis. Synonym: tin oxide. (05 Mar 2000) |
| stilbene oxide hydrolase | <enzyme> Aspect of epoxide hydrolase, EC 3.3.2.3 Registry number: EC 3.3.2.- Synonym: trans-stilbene oxide hydrolase (26 Jun 1999) |
| neutral oxide | An oxide that is neither an acid nor a base; e.g., water (hydrogen oxide, H2O). Synonym: indifferent oxide. (05 Mar 2000) |
| nitric oxide | <biochemistry> This compound is produced from L arginine by the enzyme nitric oxide synthase. Acts as a potent vasorelaxant via elevation of intracellular cGMP in vascular smooth muscle. Synthesis of nitric oxide is not confined to endothelium, isoforms of nitric oxide synthase are also found in brain, neutrophils and platelets. Synonym: endothelium derived relaxation factor. Acronym: NO (29 Dec 1997) |
| nitric-oxide reductase | <enzyme> Prior to 1992 was classified as EC 1.7.99.2; a cytochrome bc complex; genbank af002217 (norb protein) and af002661 (norz protein) are from alcaligenes eutrophus Registry number: EC 1.7.99.7 Synonym: nitric oxide reductase, norb gene product, norz gene product (26 Jun 1999) |
| nitric oxide synthase | <enzyme> An enzyme that catalyses the conversion of l-arginine, NADPH, and oxygen to citrulline, nitric oxide, and NADP+. The enzyme found in brain, but not that induced in lung or liver by endotoxin, requires calcium.There are two isoforms, one constitutive and one activated by calmodulin. Chemical name: L-Arginine,NADPH:oxygen oxidoreductase (nitric-oxide-forming) Registry number: EC 1.14.13.39 Acronym: NOS (12 Dec 1998) |
| nitrous oxide | <chemical> Nitrogen oxide (n2o). A colourless, odourless gas that is used as an anaesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream. Pharmacological action: aerosol propellants, analgesics, non-narcotic, anaesthetics, inhalation. Chemical name: Nitrogen oxide (N2O) (12 Dec 1998) |
| sulfuric oxide | SO3;forms sulfuric acid, H2SO4, by its reaction with water. Synonym: sulfuric oxide. (05 Mar 2000) |
| sulfurous oxide | <chemical> A highly toxic, colourless, nonflammable gas. It is used as a pharmaceutical aid and antioxidant. It is also an environmental air pollutant. Pharmacological action: air pollutants, environmental, antioxidants, pharmaceutic aid. Chemical name: Sulfur dioxide (12 Dec 1998) |
