RESUMO

One of the most important sources of plasma radiation, gliding arc discharge (GAD), has the potential to combine advantages of both thermal and nonthermal plasmas with destructive physical and biochemical properties. Thus, GAD may be effective when applied to the local microenvironment of leukemia cells, especially in the extracellular matrix (ECM). Blood samples from chronic myelogenous leukemia (CML) patients were studied and compared with matched control samples. Triple blood cultures for each case were exposed to GAD for different time periods (20, 40, and 60 s). Cytogenetic and biochemical parameters were investigated before and after irradiation. We observed significant consequences in ECM structure and cytome assay parameters, such as increased frequencies of dispersal cells, micronuclei, and necrotic and apoptotic cells. In addition, results showed improved values of vascular endothelial growth factor and interleukin-10 and decreased levels of collagen IV. The most effective exposure period was 40 s, which presented highly significant results. This type of energy can stop the progress and development of CML via lyses, cell spreading, and eradication of ECM, especially with the use of GAD for a period of 40 s.
