Studies of pyridoxine displacement.
Relatively little work has been done with pyridoxine displacers. Ott (1) found 2,4-dimethyl-3-hydroxy-5-hydroxymethylpyridoxine (desoxypyridoxine) to be a very potent inhibitor of pyridoxine in the metabolism of the chick. 2 molecules of inhibitor were sufficient to offset the vitamin activity of 1 molecule of pyridoxine. In the course of an investigation of antimalarials, McCasland et al. (2) ...
متن کاملSafety of pyridoxine--a review of human and animal studies.
A literature review was conducted on adverse effects associated with administration of high oral doses of pyridoxine (vitamin B6) to animals and man. The human data suggest that doses of pyridoxine greater than 500 mg/day for prolonged periods of time can result in sensory nerve damage. Doses less than 500 mg/day appear to be safe on the basis of literature reports where the compound was admini...
متن کاملStudies of In-Vitro Amlodipine and Arsenic Displacement Interaction at Binding Sites of Bovine Serum Albumin
In this study, the binding of amlodipine (a Ca ++ channel Blocker) and arsenic (metalloid) to bovine serum albumin (BSA) was studied by equilibrium dialysis(ED) method in order to have an insight into their binding chemistry to BSA. Free amlodipine concentration was increased due to addition of arsenic which reduced the binding of the compounds to BSA. However, the free fraction was not increa...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Studies on Anemia in Dogs Due to Pyridoxine Deficiency*
Nutritional microcytic anemia in puppies was first reported by Fouts et al. (1) on a synthetic ration low in pyridoxine. The anemia was curable by concentrates and later by crystalline pyridoxine (2). These authors showed that adult dogs placed on such a ration also developed the condition (3). These results have been confirmed in the authors’ laboratory (4) and further studies have been conduc...
