Abstract

 

Catalase (CAT) enzyme activities were measured in erythrocytes isolated from untreated patients with chronic leukemia, by using Aebi's method. In chronic lymphocytic leukemia, CAT activity was found to be significantly decreased and in chronic myeloid leukemia, it was found to be in normal ranges of activity although in both types of chronic leukemia, the activities were lower than the normal control group with respect to averages. These results suggest that catalase as an erythrocyte antioxidant enzyme may play an important role in chronic leukemias. [Journal of Turgut ÖzalMedical Center 1997;4(1):7-9]
