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 ...

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.

The Journal of Nutrition, 1973
Studies of the relative effects of growth hormone ( GH ) and vitamin B-6 on the in vivo uptake of «-"C-aminoisobutyric acid ( AIB ) in liver, diaphragm and heart of vitamin B-6-deficient rats were conducted. Generally, greater cellular uptake of AIB was observed in deficient than control rats. This increased uptake was particularly marked in liver. GH

Neuronal Development in Vitamin B6 Deficiency
Annals of the New York Academy of Sciences, 1990The morphological changes observed in developing brain regions associated with maternal vitamin B6 deficits are summarized in Table 4. Brain development is a complex and orderly process consisting of cell division, proliferation, migration, and maturation.

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 ...

Canadian Journal of Biochemistry, 1971
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 ...

Vitamin B-6 deficiency and renal function and structure in chronically uremic rats
The American Journal of Clinical Nutrition, 1991In preliminary studies, rats with chronic renal failure (CRF) demonstrated worsening renal function, as measured by urea clearance, when fed vitamin B-6-deficient diets. However, urea clearance is not a precise measure of glomerular filtration rate (GFR) and these studies did not indicate the mechanism for the reduced GFR.
