Sugars in the blood and urine of children following the ingestion of disaccharides.

It has previously been shown that reducing sugars are frequently excreted in the urine by mature and premature newborn babies (Haworth and McCredie, 1956; Haworth and MacDonald, 1957). Other workers, using paper chromatographic methods, have also found small amounts of sugars in the urines of children and usually higher concentrations of lactose and galactose in urines from young babies (Woolf, 1951; Apthorp, 1957; Bickel, 1959). Coant, Glowacki and Reardon (1959) found a high urinary excretion rate of sugars by premature babies which could be correlated with the amount of lactose in the feedings. This paper describes further observations on sugars in the urine and blood of newborn babies and older children following the oral ingestion of different disaccharides.
