Activities of catalase in leucocytes and glucose-6-phosphate dehydrogenase in erythrocytes of hypocatalasemia and acatalasemia.

Abstract

Catalase activity in leukocytes was 1/2 the normal value in hypocatalasemia and extremely low in acatalasemia. Glucose-6-phosphate dehydrogenase activity in erythrocytes was not significantly different between normal, hypocatalasemia and acatalasemia in 3 familes of acatalasemia, but in 1 family lower activities than normal were found in hypocatalasemia and actalasemia erythrocytes. Other enzyme activities in blood, such as alkaline phosphatase, lactate dehydrogenase, glutamic oxaloacetic and glutamic pyruvic transaminases, were not significantly different between normal subjects, hypocatalasemia and acatalasemia.
