| 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) |

| deficiency, calcium | A low blood calcium (hypocalcaemia). Hypocalcaemia makes the nervous system highly irritable with tetany (spasms of the hands and feet, muscle cramps, abdominal cramps, overly active reflexes, etc.). Chronic calcium deficiency contributes to poor mineralization of bones, soft bones (osteomalacia) and osteoporosis; and, in children, rickets and impaired growth. Food sources of calcium include dairy foods, some leafy green vegetables such as broccoli and collards, canned salmon, clams, oysters, calcium-fortified foods, and tofu. According to the National Academy of Sciences, adequate intake of calcium is 1 gram daily for both men and women. The upper limit for calcium intake is 2.5 grams daily. (12 Dec 1998) |
| dioctyl calcium sulfosuccinate | Calcium salt of bis(2-ethylhexyl)sulfosuccinate;a surface-active agent used in the treatment of constipation as a nonlaxative faecal softener. Synonym: dioctyl calcium sulfosuccinate. (05 Mar 2000) |
| docusate calcium | Calcium salt of bis(2-ethylhexyl)sulfosuccinate;a surface-active agent used in the treatment of constipation as a nonlaxative faecal softener. Synonym: dioctyl calcium sulfosuccinate. (05 Mar 2000) |
| intestinal calcium-binding protein | <protein> Calcium-binding proteins containing the EF hand motif, induced by vitamin D3. (18 Nov 1997) |
| ionised calcium | <biochemistry> The ionised calcium represents the calcium (Ca++) that is the metabolically active calcium. Normal values for ionised calcium in the bloodstream should be 4.4 to 5.3 mg/dl for adults and 4.4 to 6.0 mg/dl for children. Elevations may be seen in hyperparathyroidism, metastatic bone tumour, milk-alkali syndrome, multiple myeloma, Paget's disease, sarcoidosis, PTH-secreting tumours (paraneoplastic syndrome) and vitamin D intoxication. Lower than normal values may be seen in hypoparathyroidism, malabsorption, osteomalacia, pancreatitis, renal failure, rickets and vitamin D deficiency. (27 Sep 1997) |

| fenoprofen calcium | Calcium (±)-m-phenoxyhydratropate dihydrate;an anti-inflammatory analgesic used for treatment of mild to moderate pain and for osteoarthritis. (05 Mar 2000) |
| formol-calcium fixative | A fixative for preservation of lipids. (05 Mar 2000) |
| free calcium level | <biochemistry> The ionised calcium represents the calcium (Ca++) that is the metabolically active calcium. Normal values for ionised calcium in the bloodstream should be 4.4 to 5.3 mg/dl for adults and 4.4 to 6.0 mg/dl for children. Elevations may be seen in hyperparathyroidism, metastatic bone tumour, milk-alkali syndrome, multiple myeloma, Paget's disease, sarcoidosis, PTH-secreting tumours (paraneoplastic syndrome) and vitamin D intoxication. Lower than normal values may be seen in hypoparathyroidism, malabsorption, osteomalacia, pancreatitis, renal failure, rickets and vitamin D deficiency. (27 Sep 1997) |
| leucovorin calcium | <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) |
