Effect of different regimes of ultrawideband pulse irradiation on the state of chromatin in human cells
Abstract
Human buccal epithelial cells were exposed to ultrawideband ultrashort pulsed radiation by means of slot antenna for 1, 10, 100 and 1000 s. Surface power of cells irradiation was from 10-6 to 10-2 W/cm2. The cell exposure resulted in condensation of chromatin in cell nuclei. Changing of the exposure time not significantly affect the degree of heterochromatinization. In the case of intermittent irradiation exposure the effect chromatin condensation was not observed. There were shown individual differences in the responses to irradiation of cells from various donors.
