A Case Report: Acute Myeloid Leukemia (FAB M7)
Acute myeloid leukemia (AML-M7) is a type of pediatric AML accounting for 3–10% of primary childhood AML and children may present with a broad variety of symptoms including low-grade fever, diarrhea, easy bruising, failure to gain weight and life-threatening conditions. We report a rare case of AML .A 26-month-old boy who presented with weakness and fatigue. He was diagnosed as a case of AMLM-7...

Acute myelocytic leukemia (AML) in both children and adults is a more complex and resistant disease than acute lymphocytic leukemia. Progress has been slower and therapy more complicated, but with intensive myelosuppressive induction and further postremission therapy one-third of such patients may now achieve longterm survival and probably be cured.’-5 In the Nordic countries (Denmark, Finland,...

This enzyme, found in mammalian tissues and studied in rat tissue preparations and normal human blood components, is also present in human leukemic myeloblasts. The enzymes from both normal and leukemic leukocytes require NADPH for activity, have similar kinetics and substrate saturation ch...

متن کاملPrediction of response to chemotherapy in acute myelocytic leukemia.
Marrow specimens obtained from 23 patients with acute myelocytic leukemia were exposed to cytosine arabinoside and/or daunorubicin in vitro, and the effects of these agents on colony formation in vitro was determined. Thymidine suicide indices were determined as well, which permitted a distinction to be made between kinetic and metabolic resistance to cytosine arabinoside. The sensitivity of th...
