The high catalase activity of erythrocytes may represent protection against the oxidative degradation of haemoglobin. We have therefore studied the catalase activity in the blood of children, in which haemoglobin or erythrocytes are in some way affected. Catalase activity is decreased in unweaned children and especially during the first day of birth in premature and mature infants, showing a correlation with an unstable erythrocyte metabolism. After the first year of life until puberty, catalase activity is constant. There is no variation with sex. In the anaemias during staphylococcal infections, nephrotic disorders, acute leucoses and symptomatic polycythaemia from inherited cardiac disorder, the catalase activity is decreased. The low activity in constitutiona l haemolytic anaemia is improved by removal of the spleen. In haemorrhagic anaemias or illnesses where there is no effect on the red cell pattern, the catalase activity is normal. These results support the conclusion that catalase is an essential protective enzyme for haemoglobin and erythrocytes.
