Abstract
The amino acid nitrogen excreted in the 24 hour urine was found to be 172.6±18.5 mg and 91.8±21.1 mg for the average of 15 boys with nutritional dystrophy and for that of 15 boys without nutritional dystrophy respectively showing a significant diffence between them. The high urinary discharge of amino acid nitrogen was decreased markedly in the majority of the boys with nutritional dystrophy after an administration of riboflavin. The riboflavin deficiency seems therefore to be one of the factors governing the disturbances of the amino acid metabolism in children with nutritional dystrophy.
