| calcium leucovorin | <drug> The calcium salt of leucovorin (folinic acid); used to counteract toxic effects of folic acid antagonists, for the treatment of megaloblastic anaemias, and as an adjunct to cyanocobalamin in pernicious anaemia. Synonym: calcium folinate. (05 Mar 2000) |
|---|---|
| calcium levulinate | A hydrated calcium salt of levulinic acid; it has the usual effects of calcium administered orally or intravenously. (05 Mar 2000) |
| calcium magnesium-atpase | <enzyme> An enzyme that catalyses the hydrolysis of ATP and is activated by millimolar concentrations of either calcium or magnesium. Unlike calcium-transporting atpase it does not require the second divalent cation for its activity, and is not sensitive to orthovanadate. Registry number: EC 3.6.1.- (12 Dec 1998) |
| calcium magnesium dependent endodeoxyribonuclease | <enzyme> Similar in action but different from dnase i Registry number: EC 3.1.21.- Synonym: ca mg dnase, ca(2+)+mg(2+) dnase, calcium-magnesium endonuclease, ca-mg endonuclease (26 Jun 1999) |
| calcium mandelate | Calcium salt of mandelic acid; a urinary anti-infective agent. (05 Mar 2000) |
| calcium monohydrogen phosphate | CaHPO4-2H2O;used as a calcium and phosphorus dietary supplement. Synonym: calcium monohydrogen phosphate, secondary calcium phosphate. (05 Mar 2000) |
| calcium oxalate | <chemical> Ethanedioic acid calcium salt. The calcium salt of oxalic acid, occurring in the urine as crystals and in certain calculi. Chemical name: Ethanedioic acid, calcium salt (12 Dec 1998) |
| 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) |
| calcium pantothenate | The calcium salt of pantothenic acid; a vitamin B filtrate factor. (05 Mar 2000) |
| calcium phosphates | Calcium salts of phosphoric acid. These compounds are frequently used as calcium supplements. (12 Dec 1998) |
| calcium propionate | The calcium salt of propionic acid; an antifungal agent. (05 Mar 2000) |
| calcium pump | A transport protein responsible for moving calcium out of the cytoplasm. See: calcium ATPase. (18 Nov 1997) |
| calcium pyrophosphate | <chemical> Diphosphoric acid, calcium salt. An inorganic pyrophosphate which affects calcium metabolism in mammals. Abnormalities in its metabolism occur in some human diseases, notably hypophosphatasia and pseudogout. Chemical name: Diphosphoric acid, calcium salt (12 Dec 1998) |
| calcium pyrophosphate deposition disease | <radiology> Manifestations can occur singly or in any combination, pseudogout, acute crystal-induced synovitis with clinical symptoms analogous to gout, arthropathy, beaklike osteophytes of 2nd, 3rd metacarpal heads, subchondral cysts (especially carpal bones), unusual distribution of disease (radiocarpal/ulnar joint, patellofemoral joint), SLAC - scapholunate advanced collapse, chondrocalcinosis, triangular fibrocartilage, symphysis pubis, menisci of knee, annulus fibrosus of intervertebral disk (12 Dec 1998) |
| calcium radioisotopes | Unstable isotopes of calcium that decay or disintegrate emitting radiation. Ca atoms with atomic weights 39, 41, 45, 47, 49, and 50 are radioactive calcium isotopes. (12 Dec 1998) |
