| calcium metabolism | A set of biochemical processes which act to keep the level of calcium in the blood at a constant level, with enough around to build bones and teeth. (09 Oct 1997) |
|---|---|
| calcium metabolism disorders | Disorders in the processing of calcium in the body: its absorption, transport, storage, and utilization. (12 Dec 1998) |
| 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) |
| calcium rigor | Arrest of the heart in the fully contracted state as a result of poisoning with calcium. (05 Mar 2000) |
| calcium saccharate | Calcium d-saccharate;used as an antacid in dyspepsia and flatulence, as an antidote in carbolic acid poisoning, and as a stabiliser for calcium gluconate solution for parenteral administration. (05 Mar 2000) |
| calcium sign | In chest radiography, displacement of the line of the calcified intima of the aorta away from its outer wall, a finding in a small percentage of cases of dissection of blood in the aortic media; the expression "displaced intimal calcification" is preferred to the listed term. See: aortic dissection. (05 Mar 2000) |
