The in vitro conjugation of labelled free cholic acid with glycine and taurine in the livers of vitamin B6-deficient and pair-fed rats has been investigated. It appears from these results that vitamin B6-deficiency stimulates this conjugation, and some evidence is given which suggests that vitamin B6 may be responsible for the lower capacity of ...

Journal of Parenteral and Enteral Nutrition, 2011
Objective: In children, vitamin B6 (pyridoxine) deficiency has been described as a cause of seizures that are refractory to conventional antiepileptic medications. We describe the clinical presentation of 3 adults with refractory seizures (later diagnosed with vitamin B6 deficiency) that resolved after pyridoxine treatment. Design: Case series. Setting:

Effects of a dietary deficiency of vitamin B-6 imposed during the lactation period on the level of this vitamin in milk, liver and muscle were assessed in rats. A control diet (vitamin B-6 free basal diet supplemented with 10 mg pyridoxine . HCl/kg) was fed to all rats just before and during the gestation period.

Vitamin B−6 deficiency vs folate deficiency: comparison of responses to methionine loading in rats
The American Journal of Clinical Nutrition, 1994The plasma homocysteine response to methionine loading was assessed in vitamin B-6- and folate-deficient rats. Rats fed vitamin B-6- or folate-deficient diets for 4 wk were administered a gastric gavage of methionine (100 mg/kg body wt). Subsequent plasma analyses revealed a peak post-methionine load increase in plasma homocysteine concentration of ...

Induction of Pyridoxal Phosphate-Dependent Enzymes in Vitamin B-6 Deficient Rats
The Journal of Nutrition, 1977The effectiveness of dietary and hormonal treatments in inducing several pyridoxal phosphate-(PLP)-dependent enzymes has been examined in vitamin B-6 deficient rats. Holo- and apoenzymes of serine dehydratase and ornithine aminotransferase were inducible in both control and deficient rats by feeding them 80% casein diets or by injecting them with ...

Metabolism of pyridoxine in the liver of vitamin B-6-deficient rats
Biochimica et Biophysica Acta (BBA) - General Subjects, 1976The metabolism of [6-3H]pyridoxine - HCl was investigated in the liver of vitamin B-6-deficient rats. Rats were made vitamin B-6 deficient by feeding ad libitum for 42 days a diet lacking pyridoxine but otherwise optimal. Animals were each injected intraperitoneally with 33 muCi of [6-3H] pyridoxine - HCl and killed at different time intervals ...

Effects of Vitamin B-6 Deficiency on Selenium Metabolism in the Rat
The Journal of Nutrition, 1989Rats were fed for 23 d diets adequate or deficient in vitamin B-6 and containing selenium as either sodium selenite, selenocysteine (SeCys) or selenomethionine (SeMet). They were then injected with 75Se of the same chemical form and killed 2 d later. Tissue deposition of stable and radiotracer selenium and the activity of glutathione peroxidase (GSHPx)

Abstract Diets adequate or deficient in vitamin B-6 were supplemented or not supplemented with sulfasalazine and fed to rats for 5 weeks. After that time period, 24 hour urine samples were collected, rats were sacrificed, and liver and blood samples were collected.

Cholesterol metabolism and vitamin B6: II. Intestinal cholesterogenesis in vitamin B6 deficient rats
Lipids, 1970AbstractThe in vitro incorporation of 1‐14C‐acetate into cholesterol by vitamin B6 deficient and pair‐fed rat intestinal tissue was assayed. It was found that vitamin B6 deficiency increases, by a twofold factor, the incorporation of 1‐14C‐acetate into the cholesterol biosynthetic chain, when using a segment of the ileum, and on the other hand no ...

Measurements of the serum concentrations of the metabolites homocysteine, cystathionine, methylmalonic acid, and 2-methylcitric acid, which accumulates when vitamin B-12-, folate-, and vitamin B-6-dependent enzymatic reactions are impaired, should provide a better indication of intracellular deficiency of these vitamins.
