ABSTRACT
Leukocyte acid phosphatase and its isoenzyme composition was studied in leukemic patients to determine the specificity of different isoenzymes in leukemic leukocytes. It was found that leukocyte acid phosphatase content is significantly increased in ALL, AML, and CML patients, while CLL patients had decreased levels of acid phosphatase. The distribution and intensity of leukocyte ACP isoenzymes vary in respective leukemic condition. Thus isoenzyme ′O′ was predominant in AML and CML, while isoenzymes 1, 2 and 3 predominated in ALL. The lack of predominance of isoenzyme 3 was a feature in CLL patients. It was concluded that the isoenzyme patterns, though promising, presented inconclusive picture for diagnosis purpose and further studies on immunochemical characteristics of these isoenzymes are warranted to ascertain their cell specificity.
