Antioxidant status and superoxide anion radical generation in acute myeloid leukemia
2007
Abstract Objectives: This study was undertaken to investigate if there is a disparity in the antioxidant status and the ability of superoxide anion (O 2 − ) generation in the patients with acute myeloid leukemia (AML). Design and methods: The peripheral blood samples from thirty AML patients and thirty-six healthy subjects were collected and leukocytes, erythrocytes and plasma were separated for use in various parameter measurements. Results: The generation of O 2 − , as reflected by lucigenin-based CL (LBCL), by the leukocytes of patients with AML was found to be significantly elevated either in resting or stimuli-elicited condition as compared with that of healthy controls ( p p p Conclusions: These data suggest that altered expression of antioxidant enzymes and higher capability of O 2 − generation by leukocytes seem to be a distinct feature of AML.
