The purpose of the present study was to examine the nutritional status of vitamin B1, B2, and B6 in respect to dietary intake of these vitamins and activity coefficients of the erythrocyte enzymes transketolase, glutathione reductase, and aspartic aminotransferase in young men and women with different physical activity levels. The participants of this study were 20 women and 20 men with high ph...

INTRODUCTION Nodding syndrome was first reported in Uganda in 2003 among internally displaced populations. Risk factors for the syndrome remain unknown. We therefore explored vitamin B6 deficiency and resulting high 3-hydroxykynurenine (3-HK) levels as risk factor for nodding syndrome in Northern Uganda. METHODS Case-control study conducted in Gulu and Amuru districts. Cases were children/you...

Cysteine sulfinic acid decarboxylase activity is not affected when measured in vitro in the presence of pyridoxal phosphate in the brains of vitamin B6-deficient rats . Ac tivity of this enzyme was not detectable in the brains of vitamin B6-deficient animals when assayed in the absence of pyridoxal phosphate . The activity of cysteine sulfinic acid decarboxylase in crude particulate and soluble...

The effects of vitamin supplements and/or diet on the levels of vitamin C, vitamin B6, and vitamin B12 in milk and blood of lactating women were determined. At the end of gestation, subjects were divided into two lactation groups: supplemented (10 subjects) and nonsupplemented (seven subjects). Milk samples were collected from 5 to 7 days and 43 to 45 days postpartum. Fasting blood samples were...

Background: Mercury in any form is poisonous and mercury toxicity most commonly affects the nervous, gastrointestinal (GI) and urinary systems. The aim of this study was to investigate the specific effect associated with mercury toxicity and to evaluate the effectiveness of iron and vitamin B6 supplement on mercury-induced toxicities in rats. Methods: This experiment was performed on 25 rats...

There is increasing interest in the importance of pyridoxine in brain disorders of childhood. Convulsions have occurred in infants receiving a pyridoxine (vitamin B6) deficient diet (Coursin, 1955), and Bessey, Adam, and Hansen (1957) have shown that some infants have a greater requirement than others for this vitamin. In the deficiency state, small amounts of vitamin B6 stop the convulsions, b...
