| sodium sulforicinate | Sodium sulforicinoleate, made by combining castor oil, sulfuric acid, and sodium hydroxide and chloride; used as a solvent for iodine, iodoform, resorcinol, pyrogallol, and a number of other substances for external use. (05 Mar 2000) |
|---|---|
| sodium tartrate | Na2C4H4O6-2H2O;a laxative. (05 Mar 2000) |
| sodium taurocholate | The sodium salt of taurocholic acid, extracted from the bile of carnivora; a cholagogue. (05 Mar 2000) |
| sodium tetraborate | Na2B4O7-10H2O;used in lotions, gargles, mouthwashes, and as a detergent. Synonym: borax, sodium pyroborate, sodium tetraborate. (05 Mar 2000) |
| sodium tetradecyl sulfate | <chemical> 7-ethyl-2-methyl-4-hendecanol sulfate sodium salt. An anionic surface-active agent used for its wetting properties in industry and used in medicine as an irritant and sclerosing agent for haemorrhoids and varicose veins. Pharmacological action: sclerosing solutions, surface-active agent. Chemical name: 1-Tetradecanol, hydrogen sulfate, sodium salt (12 Dec 1998) |
| sodium thiocyanate | NaSCN;used in the management of essential hypertension. Synonym: sodium rhodanate, sodium sulfocyanate. (05 Mar 2000) |
| sodium thiosulfate | Na2S2O3-5H2O;an antidote in cyanide poisoning in conjunction with sodium nitrite; used as a prophylactic agent against ringworm infections in swimming pools and baths, and to measure the extracellular fluid volume of the body. Synonym: sodium hyposulfite. (05 Mar 2000) |
| sodium tungstoborate | Used in electron microscopy as a negative stain. (05 Mar 2000) |
| sodium, dietary | Sodium or sodium compounds used in foods or as a food. The most frequently used compounds are sodium chloride or sodium glutamate. (12 Dec 1998) |
| sodium-24 | The isotope of sodium with an atomic weight of 24, and a half-life of 14.96 hr; it emits beta and gamma rays, and is more easily prepared than the longer-lived, positron-emitting 22Na (half-life, 2.605 yr). It is used to measure extracellular fluid by indicator dilution. (05 Mar 2000) |
| sodium-calcium exchanger | An electrogenic ion exchange protein that maintains a steady level of calcium by removing an amount of calcium equal to that which enters the cells. It is widely distributed in most excitable membranes, including the brain and heart. (12 Dec 1998) |
| sodium-hydrogen antiporter | A plasma membrane exchange glycoprotein transporter that functions in intracellular pH regulation, cell volume regulation, and cellular response to many different hormones and mitogens. (12 Dec 1998) |
| sodium-potassium pump | A membrane-bound transporter that maintains the high potassium and low sodium intracellular concentrations relative to the extracellular medium. This exchange is accomplished at the expense of cellular energy in the form of ATP. (05 Mar 2000) |
| sodium-potassium-exchanging atpase | <enzyme> An enzyme that catalyses the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane atpase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients. Chemical name: ATP phosphohydrolase (sodium-potassium-transporting) Registry number: EC 3.6.1.37 (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) |
