| 1,25(OH)(2)D(3) | 1, 25(OH)(2) Vitamin D(3 |
| vitamin B12 | <biochemistry> Member of the water soluble B vitamin group, important in the proper function of the nervous system and important in proper carbohydrate, protein and fat metabolism. (27 Sep 1997) |
|---|---|
| vitamin B12 absorption test | <investigation> This test measures the amount of vitamin B12 in the urine after ingesting a dose of B12. This test evaluates vitamin B12 absorption. The cells in the stomach produce a substance known as intrinsic factor. This substance combines with B12 to allow absorption in the distal ileum. The patient is given a small dose of radioactive B12 which can then be detected in the patients urine. Pernicious anaemia is the clinical result of B12 deficiency. Conditions that can result in an abnormal Schilling test include: deficiency of intrinsic factor, malabsorption or the development of an antibody to intrinsic factor. The Schilling test can be performed with or without administration of intrinsic factor to determine what the underlying cause for pernicious anaemia. Laxative use, renal insufficiency and hypothyroidism can all interfere with the results of this test. (27 Sep 1997) |
| vitamin B12 deficiency | A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). (27 Sep 1997) |
| vitamin B12 neuropathy | A subacute or chronic disorder of the spinal cord, such as that occurring in certain patients with vitamin B12 deficiency, characterised by a slight to moderate degree of gliosis in association with spongiform degeneration of the posterior and lateral columns. Synonym: combined sclerosis, combined system disease, funicular myelitis, Putnam-Dana syndrome, vitamin B12 neuropathy. (05 Mar 2000) |
| vitamin B12 with intrinsic factor concentrate | A combination of vitamin B12 with suitable preparations of the mucosa of the stomach or intestine of domestic animals used for food by humans. (05 Mar 2000) |
| folic acid | <biochemistry> Pteridine derivative that is abundant in liver and green plants and is a growth factor for some bacteria. The biochemically active form is tetrahydrofolate (see folate). (12 Nov 1997) |
| folic acid antagonist | <pharmacology> A chemical which inhibits a cells capacity to use folic acid and so prevent cell division, for example methotrexate. See: chemotherapy. (12 Nov 1997) |
| folic acid antagonists | Inhibitors of the enzyme, dihydrofolate reductase (tetrahydrofolate dehydrogenase), which converts dihydrofolate (fh2) to tetrahydrofolate (fh4). They are frequently used in cancer chemotherapy. (12 Dec 1998) |
| folic acid conjugate | A folate with three molecules of glutamic acid (pteropterin) instead of one, or with seven (pteroylheptaglutamic acid or vitamin Bc conjugate). (05 Mar 2000) |
| folic acid deaminase | <enzyme> Chemotaxis regulating enzyme; splits folic acid into 6-hydroxymethylpterin and p-aminobenzoylglutamic acid Registry number: EC 3.5.4.- Synonym: folic acid inactivating enzyme, folic acid c9-n10 cleaving enzyme (26 Jun 1999) |
| folic acid deficiency | A nutritional condition produced by a deficiency of folic acid in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anaemia, macrocytic anaemia, and megaloblastic anaemia. It is indistinguishable from vitamin b 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in b 12 deficiency do not occur. (merck manual, 16th ed) (12 Dec 1998) |
| folic acid deficiency anaemia | Anaemia due to deficiency of folic acid, characterised by large-sized red blood cells (macrocytosis) and presence of large nuclei in erythroid precursor cells (megaloblasts) in the bone marrow. (05 Mar 2000) |
| folic acid oxidase | <enzyme> Enzyme from human red blood cell membranes; catalyses oxidation of folic acid to pterin-6-aldehyde plus p-aminobenzoylglutamic acid in presence of h2o2; singlet oxygen is involved Registry number: EC 1.11.- (26 Jun 1999) |
| coenzyme B12 | <biochemistry> A coenzyme derived from cobalamine which is involved in carbon skeletal rearrangements. It is the only biomolecule known that has a carbon-metal bond. (09 Oct 1997) |
| pseudovitamin B12 | <biochemistry> Cobamide cyanide phosphate, 3'-ester with 7-alpha-d-ribofuranosyladenine, inner salt; vitamin B12 with adenine replacing dimethylbenzimidazole; one of several substances produced during anaerobic fermentation by certain organisms in bovine rumen contents; it is chemically closely similar to vitamin B12 (cyanocobalamin) but without, in humans, the physiologic action of the vitamin.
