Abstract:
Objective To study the effects of alternating magnetic field with different intensities on the proliferation of human squa-mous tongue cancer cells in vitro. Methods Viable cells with the OD value cell and flow cytometry were revealed through MTT assay to evaluate the proliferation and apeptosis and cell cycle respectively after the cells were exposed to electromagnetic fields of different intensity (5mT,8mT,11mT) once per day lasting 1 hour for 3 days. The sham -exposure controls were correspondingly established. Results We compared the electromagnetic field groups with the normal groups by MTT assay after 24,48,72 hours. By analyzing the data in SPSS sta-tistical software , we found that the OD value of electromagnetic field groups was significantly less than that of the control groups (P <0.01) . The rates of apoptosis cells by flow cytometry revealed that EMF groups had no change as compared with control groups. But the cell cycle displayed significant chang at 0.5rot. Conclusion The cells displayed significant changes with obvious Tca8113 cell prolifera-tion inhibition and hold - up cell cycle after being exposed to alternating magnetic field of different intensity. But human squamous tongue cancer ceils could not be induced to apeptosis.
