Values of hour excretion of vitamins B1, B2, B6 and PP with urine in children of 9-13 years, studied under conditions of normal consumption of these vitamins, were estimated considering the correlation between the vitamins B concentration in blood and excretion of their metabolites with urine as well as using these parameters dependence on content of the vitamins in daily ration; for this purpose 35 adult persons and 31 children of both sexes were examined. Normal rate of riboflavin excretion with urine constituted 10-11 micrograms/h in children of this age, while of thiamine-11-12 micrograms/h. Under conditions of normal thiamine consumption, activity of erythrocyte transketolase, measured after preinactivation of transaldolase, exceeded 35 mumol/h/I ml of erythrocytes. Rates of excretion with urine of 4-pyridoxic acid and I-methyl nicotinamide were similar both in children and in adult persons and were equal to more than 40 micrograms/h and 400-600 micrograms/h, respectively.
