| calcium sulfite | Used as an intestinal antiseptic, and locally in the treatment of parasitic skin diseases. (05 Mar 2000) |
|---|
| sodium hydrogen sulfite | NaHSO3;acid sodium sulfite, used in gastric and intestinal fermentation, externally in the treatment of parasitic diseases, and as an antioxidant in certain injections (s. Metabisulfite). Synonym: sodium hydrogen sulfite, sodium pyrosulfite. (05 Mar 2000) |
|---|---|
| sodium sulfite | Na2SO3-7H2O;has been used for the relief of intestinal fermentation, and externally for aphthous stomatitis. (05 Mar 2000) |
| sulfite | A salt of sulfurous acid; elevated in cases of molybdenum cofactor deficiency. Sulfite dehydrogenase, an oxidoreductase catalyzing the reaction of sulfite with 2 ferricytochrome c and water to sulfate and 2-ferrocytochrome c. Sulfite oxidase, a liver oxidoreductase (haemoprotein) catalyzing the reaction of inorganic sulfite ion with O2 and water to produce sulfate ion and H2O2; a lower activity of this enzyme is observed in cases of molybdenum cofactor deficiency. Sulfite reductase, oxidoreductase catalyzing reduction of sulfite to H2S using some reduced acceptor. (05 Mar 2000) |
| sulfite oxidases | <enzyme> A molybdohemoprotein which catalyses the terminal reaction in the oxidative degradation of sulfur-containing amino acids with the formation of a sulfate. Cytochrome c, ferricyanide and molecular oxygen can act as acceptors. A deficiency is manifested by brain damage and mental deterioration. Utilises ferricytochrome c as acceptor. Uses molecular oxygen. Registry number: EC 1.8.3.1 (12 Dec 1998) |
| sulfite reductases | <enzyme> Hydrogen sulfide:(acceptor) oxidoreductases. Enzymes which reversibly catalyze the oxidation of hydrogen sulfide in the presence of various acceptors to sulfite and a reduced acceptor. Utilises NADP+ as the acceptor. Utilises oxidised ferredoxin as acceptor and EC 1.8.99.1 will utilise a variety of acceptors. Registry number: EC 1.8.- (12 Dec 1998) |
| exsiccated sodium sulfite | Anhydrous sodium sulfite, used as a preservative in pharmaceutical preparations. (05 Mar 2000) |
| benzoylpas calcium | 4-Benzamidosalicylic acid calcium salt;an antituberculous agent. (05 Mar 2000) |
| calcium | <element> An element taken in through the diet that is essential for a variety of bodily functions, such as neurotransmission, muscle contraction and proper heart function. Imbalances of calcium can lead to many health problems and excess calcium in nerve cells can cause their death. (22 May 1997) |
| calcium-45 | <radiobiology> Most easily available of the radioactive calcium-45 isotopes; beta-emitter with a half-life of 162.7 days; used as a tracer. (05 Mar 2000) |
| calcium-47 | <radiobiology> A radioisotope of calcium with a half-life of 4.54 days, used in the diagnosis of disorders of calcium metabolism. (05 Mar 2000) |
| calcium alginate | A topical haemostatic. (05 Mar 2000) |
| calcium aminosalicylate | The calcium salt of p-aminosalicylic acid, with the same uses. (05 Mar 2000) |
| calcium antagonist | calcium channel-blocking agent |
| calcium ATPase | <enzyme> Usually used of the calcium pumping ATPase present in high concentration as an integral membrane protein of the sarcoplasmic reticulum of muscle. This pump lowers the cytoplasmic calcium level and causes contraction to stop. Normal function of the pump seems to require a local phospholipid environment from which cholesterol is excluded. (18 Nov 1997) |
| calcium benzoylpas | Calcium 4-benzamidosalicylate;an antituberculous agent. (05 Mar 2000) |
