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)

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 ...

The Journal of Nutrition, 1981
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.

The Journal of Nutrition, 1976
Levels of vitamin B-6 in milk from pyridoxine deficient dams were used as an indicator of the ability of pyridoxine to protect offspring against the effects of the deficiency. Sprague Dawley rats were fed a basal diet containing 30.0 (control) or 1.2 (deficient) mg pyridoxine-HC1/kg diet from weaning throughout growth, gestation and until 5 days ...

Connective Tissue Integrity is Lost in Vitamin B-6—Deficient Chicks
The Journal of Nutrition, 1995The objective of the present investigation was to characterize further the connective tissue disorder produced by pyridoxine (vitamin B-6) deficiency, as previously evidenced by electron microscopy. Following the second post-natal week, fast growing male chicks were deprived of pyridoxine for a 1-mo period.

Humoral Immunity in Chicks Experiencing Marginal Vitamin B-6 Deficiency
The Journal of Nutrition, 1984An economical vitamin B-6-deficient ration that was palatable to broiler chickens was prepared and fed to 1-day-old chicks. The experimental ration was a typical soy-glucose ration. Vitamin B-6 was removed by washing the soybean meal with water.

Effects of Sugars and Vitamin B-6 Deficiency on Oxalate Synthesis in Rats
The Journal of Nutrition, 1984Rats fed diets containing galactose as the source of carbohydrate excreted greater amounts of endogenously formed oxalic acid in their urine, compared to rats fed glucose, fructose or sucrose. Rats fed lactose showed similar but less marked effects. The greatest amounts of urinary and fecal oxalate excretions were observed among rats fed galactose and ...

[Vitamin B 6 deficiency anemia].
Schweizerische medizinische Wochenschrift, 1976The course of spontaneous vitamin B6 deficiency anemia in a 57-year-old woman is reported. The anemia was characterized by hypochromasia of the erythrocytes, hyperferricemia, absence of hemolysis, and hyperplastic, ineffective, sideroblastic erythropoiesis of the bone marrow. It was corrected by oral vitamin B6 therapy.

Gluconeogenesis in Meal-Fed, Vitamin B-6-Deficient Rats
The Journal of Nutrition, 1980Male weanling rats were meal-fed (2 hours daily) on a vitamin B-6-deficient diet for 8 weeks; the controls were pair-fed. Vitamin B-6 deficiency led to the expected decreases in the activities of hepatic alanine and aspartate aminotransferases but did not influence those of glutamate dehydrogenase (EC 1.4.1.2), pyruvate carboxylase (EC 6.6.1.1 ...

Effect of vitamin B-6 deficiency on fasting plasma homocysteine concentrations
The American Journal of Clinical Nutrition, 1992The catabolism of homocysteine through cystathionine synthesis requires pyridoxal-5'-phosphate, thus the effect of vitamin B-6 deficiency on plasma homocysteine concentrations was evaluated. Total fasting plasma homocysteine concentrations were measured in 11 elderly subjects aged 64.4 +/- 1.7 y (mean +/- SE) who consumed a vitamin B-6-deficient diet ...
