although leukocytes from all 13 acute lymphoblastic leukemia patients examined had high terminal deoxynucleotidyl transferase ( terminal transferase ) activity ( 20 to 100 units/mg of cellular dna , where 1 unit equals 1 nmole of nucleotide polymerized in 1 hr ) and those from 21 acute myelocytic leukemia patients had low terminal transferase activity ( 0.2 to 2 units/mg of cellular dna ) , the bone marrow and peripheral blood leukocytes from 2 patients with acute myelocytic leukemia , diagnosed on the basis of clinical features and the morphology , cytochemistry , and cytogenetics of the leukemic cells , had terminal transferase activity ( 39 to 52 units/mg of cellular dna ) equivalent to that found in leukemic lymphoblasts .
