| vitamins | For the various vitamins see Vitamins. The word vitamin was coined in 1911 by the warsaw-born biochemist casimir funk (1884-1967). at the lister institute in london, funk isolated a substance that prevented nerve inflammation (neuritis) in chickens raised on a diet deficient in that substance. He named the substance vitamine because he believed it was necessary to life and it was a chemical amine. The e at the end was later removed when it was recognised that vitamins need not be amines. The letters (a, b, c and so on) were assigned to the vitamins in the order of their discovery. The one exception was vitamin k which was assigned its k from koagulation by the danish researcher henrik dam. (12 Dec 1998) |
| fat-soluble vitamins | Those vitamin's, soluble in fat solvents (nonpolar solvents) and relatively insoluble in water, marked in chemical structure by the presence of large hydrocarbon moieties in the molecule; e.g., vitamin's A, D, E, K. (05 Mar 2000) |
| acidulated phosphate fluoride | <chemical> Phosphoric acid, mixt. With sodium fluoride (naf). A sodium fluoride solution, paste or powder, which has been acidulated to pH 3 to 4 and buffered with a phosphate. It is used in the prevention of dental caries. Pharmacological action: fluorides, topical. Chemical name: Phosphoric acid, mixt. With sodium fluoride (NaF) (12 Dec 1998) |
| calcium fluoride | <chemical> Calcium fluoride. Occurring in nature as the mineral fluorite or fluorspar. It is the primary source of fluorine and its compounds. Pure calcium fluoride is used as a catalyst in dehydration and dehydrogenation and is used to fluoridate drinking water. Chemical name: Calcium fluoride (CaF2) (12 Dec 1998) |
| phenylmethylsulfonyl fluoride | <chemical> Alpha-toluenesulfonyl fluoride. An enzyme inhibitor that inactivates irc-50 arvin, subtilisin, and the fatty acid synthetase complex. Pharmacological action: enzyme inhibitors, protease inhibitors. Chemical name: Benzenemethanesulfonyl fluoride (12 Dec 1998) |
| silver fluoride | AgF2-H2O;an antiseptic. (05 Mar 2000) |
| sodium fluoride | <chemical> Sodium fluoride (naf). A source of inorganic fluoride which has been used orally and topically to prevent dental caries. It is also effective as a pesticide and in the therapy of osteoporosis. Pharmacological action: fluorides, topical. Chemical name: Sodium fluoride (NaF) (12 Dec 1998) |
| stannous fluoride | A preparation containing not less than 71.2% of stannous tin and not less than 22.3% nor more than 25.5% of fluoride; used as a prophylactic against caries in dentistry. (05 Mar 2000) |
| fluoride | <chemical> The fluoride ion. Low levels of fluoride in drinking water markedly decrease the incidence of dental caries, probably because bacterial metabolism is much more sensitive to low fluoride levels. (18 Nov 1997) |
| fluoride number | The percent inhibition of pseudocholinesterase produced by fluorides; used to differentiate normal from atypical pseudocholinesterases. See: dibucaine number. (05 Mar 2000) |
| fluoride poisoning | Gen or unspecified fluoride; prefer /pois with specific fluoride term (12 Dec 1998) |
| abortion, multiple | Couples who have had 2 or more miscarriages (spontaneous abortions) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| amyloidosis of multiple myeloma | Foci of amyloidosis in mesenchymal tissues of some persons with multiple myeloma; no direct relation between amyloid and Bence Jones protein is conclusively known. (05 Mar 2000) |
