Sažetak
Aim of study was to evaluate and compare influence of two different radiofrequency/microwave (RF/MW) fields of 864 and 935 MHz frequency on the growth, colony-forming ability and viability of continuous cell line V79. Cell samples in concentration of 1x104 each, were exposed to continuous wave frequencies of 864 and 935 MHz for 1, 2 and 3 hours. Exposed samples were matched with sham-exposed controls. Specific absorption rate (SAR) was calculated to be 0.08 W/kg for 864 MHz or 0.12 W/kg for 935 MHz field. Cell growth and viability was determined by cell counts every day during five days after exposure. Colony-forming ability was assessed by colony number seven days after exposure. The growth of the 864 MHz irradiated cells showed significant decrease after two- and three-hour exposure 72 hours after irradiation (p<0.05). Cells exposed to 935 MHz microwaves for three hours showed significant decrease 72 hours after exposure (p<0.05). Colony-forming ability and cell viability exposed to 864 MHz or 935 MHz microwaves did not significantly differ from the controls. The applied RF/MW fields showed similar effect on growth, colony-forming ability and viability of V79 cells. Cell growth findings reveal time-dependent influence of both, 864 and 935 MHz frequency field.
