Catalytic photometric determination of cobalt in the urine of children with increased arterial pressure.

Abstract

The concentration of the microelement cobalt in the urine of healthy children and of children with increased arterial pressure was studied. The values of the cobalt content in the urine of clinically healthy children were 0.22 +/- 0.06 mumol/l in boys and 0.21 +/- 0.11 mumol/l in girls, which were taken as normal, while the values in children with increased arterial pressure were 0.39 +/- 0.17 mumol/l in boys and 0.28 +/- 0.06 mumol/l in girls, which are considered to be increased. These results were explainable by incomplete assimilation and excretion of a great part of the cobalt in the urine of children with elevated arterial pressure (AP).
