[Diurnal urinary excretion of oxalic acid in healthy children of different age groups]. 1984

D Banaś, and B Gołabek

The oxalic acid concentration in 24 hour urine of 94 healthy children, aged 1 to 18 years, were determined. The colorimetric method of Slodgkinson and Williams in modification of Rozentall was used to determine the oxalic acid concentration. Obtained results were analysed in following age groups: 1-3 years, 3-6 years, 9-14 years and 14-18 years. Table I shows the results of determinations of oxalic acid concentration in 24 hour urine and numbers of children in age groups.
