The influence of vitamin B6 on linoleic (LA), alpha-linolenic (ALA), arachidonic (AA), eicosapentaenoic (EPA) and docosahexaenoic (DHA) acid content in serum and liver of rats fed with protein-energy deficient diets for 90 d, was studied. To estimate the effect of dietary supplementation with vitamin B6 on the composition and level of fatty acids in the serum and liver of rats, two experiments ...

Abderhalden (1) injected the pyrimidine and thiazole moieties of thiamine in mice and rats with the object of investigating the biosynthesis of thiamine and observed the induction of running fits. Its cause was further proved to be the pyrimidine moiety, i.e., 2-methyl-4-amino-5-hydroxymethylpyrimidine (OMP). Makino and Sasaki (2) reported the induction of running fits after in jecting this com...

Background: Nausea and vomiting are the common side-effects of chemotherapy in children with malignancy. In this study, the effectiveness of vitamin B6 in reducing the chemo-induced nausea and vomiting (CINV) in children was tested. Material and methods: A triple-blind clinical trials was performed on 100 children with malignancy referring to the pediatric clinic of Amir Kabir Hospital, Arak, ...

Among various cardiovascular risk factors, hyperhomocysteinemia has recently emerged as an important one. While there are currently no doubts on the relationship between severe hyperhomocysteinemia and vascular disease, some uncertainty still persists on the relationship between mild hyperhomocysteinemia and vascular disease. Several group B vitamins, namely vitamin B6, vitamin B12, and folate,...

Dietary intake and/or circulating concentrations of vitamin B6 have been associated with risk of cancer, but results are inconsistent and mechanisms uncertain. Pyridoxal 5'-phosphate (PLP) is the most commonly used marker of B6 status. We recently proposed the ratio 3-hydroxykynurenine/xanthurenic acid (HK/XA) as an indicator of functional vitamin B6 status, and the 4-pyridoxic acid (PA) /(pyri...
