During several weeks riboflavin supplementation of lactating African women, which reduced their mean activation coefficient of erythrocyte glutathione reductase (EGRAC) from 1.65 to 1.21 and initiated an improvement in clinical deficiency signs, measurements were made of physiological functions which may be connected with riboflavin status. No specific response to the supplement could be detect...
1. Thiamin, riboflavin and pyridoxine status of 'low-income-group' mothers and their newborn infants was assessed by analysing paired samples of maternal and umbilical cord blood for erythrocyte transketolase (EC 2.2.1.1) (ETK), erythrocyte glutathione reductase (EC 1.6.4.2) (EGR), and erythrocyte aspartate aminotransferase (EC 2.6.1.1) (EAA) activities. 2. The vitamin status of the infants was...
Riboflavin-responsive forms of multiple acyl-CoA dehydrogenation deficiency (RR-MADD) have been known for years, but with presumed defects in the formation of the flavin adenine dinucleotide (FAD) co-factor rather than genetic defects of electron transfer flavoprotein (ETF) or electron transfer flavoprotein-ubiquinone oxidoreductase (ETF-QO). It was only recently established that a number of RR...
Flavin adenine dinucleotide (FAD), synthesized from riboflavin, is redox cofactor in energy production and plays an important role in cell survival. More recently, riboflavin deficiency has been linked to developmental disorders, but its role in stem cell differentiation remains unclear. Here, we show that FAD treatment, using DMSO as a solvent, enabled an increase in the amount of intracellula...
1. Male Wistar rats were given isoenergetic, semi-synthetic diets deficient in thiamin, riboflavin, pyridoxine or all the B-vitamins. 2. In rats given these deficient diets the 'sleeping time' induced with pentobarbital (PB) and the 'paralysis time' with zoxazolamine (Zz) were prolonged. 3. The tolerance effect against both drugs was nearly independent of the levels of B-vitamins in the diets. ...
In forty-eight rats kept on a basal diet deficient in the vitamin B complex and supplemented with vitamin B(1) and riboflavin or with vitamin B(1), riboflavin and vitamin B(6), various pathological changes in the liver were observed. These changes were characterized mainly by parenchymatous and fatty degeneration, focal and massive necrosis, hyperemia and hernorrhage and, in some of the rats, b...
