J acid
| sodium pump | <enzyme> A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell and 2 potassium ions in, for each ATP hydrolysed. The sodium gradient established is used for several purposes (see facilitated diffusion, action potential), while the potassium gradient is dissipated through the potassium leak channel. Must not be confused with a sodium channel. (18 Nov 1997) |
|---|---|
| sodium pyroborate | Na2B4O7-10H2O;used in lotions, gargles, mouthwashes, and as a detergent. Synonym: borax, sodium pyroborate, sodium tetraborate. (05 Mar 2000) |
| sodium pyrosulfite | 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 radioisotopes | Unstable isotopes of sodium that decay or disintegrate emitting radiation. Na atoms with atomic weights 20-22 and 24-26 are radioactive sodium isotopes. (12 Dec 1998) |
| sodium-responsive periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| sodium rhodanate | NaSCN;used in the management of essential hypertension. Synonym: sodium rhodanate, sodium sulfocyanate. (05 Mar 2000) |
| sodium ricinoleate | Sodium ricinate, the sodium salt of ricinoleic acid; a sclerosing agent similar in action to morrhuate sodium. (05 Mar 2000) |
| sodium salicylate | <chemical> A non-steroidal anti-inflammatory agent that is less effective than equal doses of aspirin in relieving pain and reducing fever. However, individuals who are hypersensitive to aspirin may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as aspirin, but there is less occult gastrointestinal bleeding. Pharmacological action: non-steroidal anti-inflammatory agents, cyclooxygenase inhibitors. Chemical name: Benzoic acid, 2-hydroxy-, monosodium salt (12 Dec 1998) |
| sodium selenite | <chemical> Selenious acid, disodium salt. It is used therapeutically to supply the trace element selenium. Chemical name: Selenious acid, disodium salt (12 Dec 1998) |
| sodium silicofluoride | Na2SiF6;used (in dilute solutions) as an antiseptic and deodorant, and for fluoridation of drinking water. Synonym: sodium fluosilicate, sodium silicofluoride. (05 Mar 2000) |
| sodium stearate | Stearic acid sodium salt, used as a pharmaceutical adjuvant in ointments, creams, and suppositories. (05 Mar 2000) |
| sodium sulfate | Na2SO4-10H2O;an ingredient of many of the natural laxative waters, and also used as a hydragogue cathartic. Synonym: Glauber's salt. (05 Mar 2000) |
| sodium sulfite | Na2SO3-7H2O;has been used for the relief of intestinal fermentation, and externally for aphthous stomatitis. (05 Mar 2000) |
| sodium sulfocarbolate | Has been used in tonsillitis and as an intestinal antiseptic; has no antiseptic properties. Synonym: sodium sulfocarbolate. (05 Mar 2000) |
| sodium sulfocyanate | NaSCN;used in the management of essential hypertension. Synonym: sodium rhodanate, sodium sulfocyanate. (05 Mar 2000) |
