研究の主なアウトカム(著者による)

Growth curves of exposed cells showed a significant decrease after 2 and 3 hours of exposure on experimental day 3, respectively, in comparison to sham exposed cells. Both, the colony forming ability and cell viability of exposed cells did not significantly differ from sham exposure condition.
In conclusion, under strictly controlled laboratory conditions, applied radiofrequency irradiation significantly affected cell proliferation kinetics but not cell viability or ability of V79 cells to form colonies.
