The purpose of this study was to investigate the effects of vitamin B6 (Vit B6) on oxidant and antioxidant status in streptozotocin-induced diabetic rats. Thirty-two Wistar rats were divided into four groups: control (C), control + Vit B6 group (C + Vit B6), diabetes (D), and diabetes + Vit B6 group (D + Vit B6). Vit B6 (4 mg/kg body weight) was administered in drinking water for 4 weeks after ...
Five patients with gyrate atrophy of the choroid and retina were examined ophthalmologically, especially ophthalmoscopically, to evaluate trials of vitamin B6 (pyridoxine) or supplementary proline. The oral administration of vitamin B6 was tried in two patients. The vitamin did not alter the serum ornithine level and the progression of chorioretinal atrophy in one patient (case 2). Despite a re...
BACKGROUND Nausea and vomiting are the common symptoms of early pregnancy. Without treatment, vomiting can complicate the pregnancy, so it must be reduced. Wide varieties of treatment have been used for nausea and vomiting in pregnancy. This study compared the effectiveness of vitamin B6 and dimenhydrinate for gestational nausea and vomiting. MATERIALS AND METHODS One hundred and forty pregna...
Treatment with several antiepileptic drugs (AED) is associated with lower serum concentrations of folate or vitamin B12. This prospective monocenter study analyzed vitamin B6 blood levels in 400 serial patients with epilepsy, AED-treated (n=385), untreated (n=15) and healthy controls (n=233). The mean plasma vitamin B6 levels of the AED-treated (12.1±10.1; p=0.093) and the untreated patients (1...
We have investigated the mechanism by which vitamin B6 acts to modulate steroid hormone-mediated gene expression. We show that the level of glucocorticoid-induced gene expression from simple promoters, containing only hormone response elements and a TATA sequence, was not affected by alterations in intracellular vitamin B6 concentration. However, modulation of hormone-induced gene expression wa...
BACKGROUND B-vitamins are essential for one-carbon metabolism and have been linked to colorectal cancer. Although associations with folate have frequently been studied, studies on other plasma vitamins B2, B6, and B12 and colorectal cancer are scarce or inconclusive. METHODS We carried out a nested case-control study within the European Prospective Investigation into Cancer and Nutrition, inc...
Patients with rheumatoid arthritis have subnormal vitamin B6 status, both quantitatively and functionally. Abnormal vitamin B6 status in rheumatoid arthritis has been associated with spontaneous tumor necrosis factor (TNF)-alpha production and markers of inflammation, including C-reactive protein and erythrocyte sedimentation rate. Impaired vitamin B6 status could be a result of inflammation, a...
BACKGROUND Vitamin deficiency is a cause of health related problems in elderly people. The aims were to study associations between vitamin B6 (B6) and diseases (primarily functional gastrointestinal disorders) in elderly people in nursing homes, the prevalence of B6 deficiency and factors associated with B6 deficiency. METHODS This cross-sectional study included residents in nursing homes. De...
background : since premenstrual syndrome (pms) can cause suicide, dissociation of familial relationships, abnormalities in the daily work and inter-personal relationships in the patients, and bring about direct and indirect economic burden for the society, it is important to resolve the problems of the patients. the objective of the current study is to determine the effect of magnesium (mg), co...
Vitamin B6 deficiency was induced in mice by maintenance for 4 weeks on a vitamin B6-free diet. Tryptophan metabolism was assessed by determining the urinary excretion of tryptophan metabolites, the metabolism of [14C]tryptophan in vivo and the formation of tryptophan and niacin metabolites by isolated hepatocytes. The vitamin B6-deficient animals excreted more xanthurenic acid and 3-hydroxykyn...
