Objective To investigate the mechanism on the irradiation effect of low power millimeter waves (MMW) to HL60 leukemia cells. Methods HL60 cells
irradiated by millimeter wave at frequency of 41.32 GHz (mean power density <2 mW/cm
2
)
were divided into 5 groups according to the irradiation time (0
15
30
45
60 min groups). The irradiation effect to cell proliferation was detected by cell counting
proliferating cell nuclear antigen (PCNA) immunohistochemical staining and quantitative analysis. Light microscopy and electron microscopy were used to observe the morphological changes of irradiated cells. Results The proliferation activity and number of PCNA-positive cells were increased in HL60 cell after 45 and 60 min MMW irradi
ation. There was no difference in the morphology between HL-60 cells exposed to MMW and shamexposed group. Ultrastructure changes were consistent with cell proliferation. Conclusion Low power MMW irradiation may promote HL60 cell proliferation.
