RESONANCE EFFECT OF LOW-INTENSITY MILLIMETER WAVES ON THE CHROMATIN CONFORMATIONAL STATE OF RAT THYMOCYTES

The method of anomalous viscosity time dependencies (AVTD) was modifie d for the study of the changes in the chromatin conformational state ( CCS) of rat thymocytes of the Wistar line. The response of the thymocy tes of male rats to low-intensity millimeter waves (MMW) was examined. It was shown that MMW at power densities (PD) of 1 mu W/cm(2) produce d a resonance effect on the CCS in the frequency range of 41.56-41.67 GHz. The resonance frequency of the cell response did not vary signifi cantly among five examined rats and was determined to be 41.61 +/- 0.0 1 GHz. A halfwidth of resonances was averaged to 40 MHz. The power dep endence of the resonance effect was measured in the range of 10-(11)-1 0(-4) W/cm(2) Statistically significant changes in CCS were registered , starting with 10(-9) W/cm(2). Right- and left-handed circularly pola rized MMW were shown to differ in efficiency at the resonance frequenc y. The established regularities in the thymocyte response to low-inten sity MMW was very similar to those which have been previously found fo r E. coli cells.
