“…Microwave-induced chromatin condensation was later reported using the method of chromatin anomalous viscosity time dependencies (AVTD) in human lymphocytes [7]. Simultanously, we demonstrated that the heterochromatin granule quantity (HGQ) increased after microwave irradiation of different circular polarization (f=42,25 GHz) and also by irradiation produced by the cell phone [8]. Group of I. Belyaev demonstrated the microwave-induced formation of foci contained tumor suppressor p53-binding protein 1 (53BP1) and phosphorylated histone H2AX (γ-H2AX) in the chromatin of human lymphocytes [9].…”

The effects of ultra wideband pulse radiation on human cells were investigated. The density of the flow of energy on the surface of irradiated object varied from 10−6 to 10−2 W/cm2 with exposure of 10 s. It was shown that heterochromatin granule quantity in cell nuclei increased under the influence of radiation from 10−4 to 10−2 W/cm2. In some intervals the effect increased with irradiation dose. At irradiation intensity 10−3 W/cm2 the process of heterochromatin granule formation was fully reversible after 2 h of recovery; at intensity 10−2 W/cm2 the reversion of irradiation effects was not full. The data obtained indicated the strong biological activity of ultra wideband ultra short pulse radiation.

The process of recovery from ultrawideband pulse irradiation was studied in isolated human buccal epithelium cells. The influence of irradiation was registered by the effect of chromatin condensation. Chromatin condensation was determined in cell nuclei by the method of heterochromatin granules counting in orcein stained cells. Irradiation induced chromatin condensation. After irradiation at the intensity of 1 mW/sm 2 cell recovery was observed after 1 hour. After 2 hours of recovery the level of heterochromatinization became close to the control level. After irradiation at the intensity of 10 mW/sm 2 no full recovery was observed.

“…Одним из важнейших факторов, изменяющим экологическую ситуацию, является электромагнитное поле антропогенного происхождения. Анализ последствий даже кратковременных воздействий сверхвысоких частот (ЭМИ КВЧ) на проявление комплекса генетически детерминированных адаптивных признаков является весьма актуальной задачей [1], которая успешно решается при помощи классического объекта генетических исследований -Drosophila melanogaster [2][3][4][5][6][7][8]. Изменение характера проявлений адаптивно важных признаков у дрозофилы после воздействия микроволн показано многими авторами, но результаты значительно различаются в зависимости от используемого диапазона длин волн, интенсивности и длительности облучения, фазы развития дрозофилы, на которой проводили облучение, а также других условий эксперимента.…”

“…Негативный эффект на плодовитость мух оказывало излучение с различной эллиптической поляризацией. При сравнении линейно поляризованного, правополяризованного и левоволяризованного излучений одинаковой мощности показано, что наибольший эффект оказывало левополяризованное излучение [8]. Основываясь на данных об усилении эффекта трансинактивации гена brown D , авторы предположили, что наблюдаемый эффект является проявлением повышения степени конъюгации хромосом в интерфазном ядре.…”

Aim. The aim of the present investigation was to study the effect of microwave irradiation of Drosophila melanogaster females on parameters of fitness of Drosophila. Methods. Three Drosophila stocks were used: stock whiteapricot (wa), and two stocks, obtained by saturation of the wild-type stocks Canton-S and Oregon-R with mutation wa (waC-S and waOr). The Drosophila females were exposed to microwave radiation (f=37.5 GHz; P=250 μW/cm), exposure time was 60 sec. Drosophila females were exposed at two different stages of eggs development: during 1–2 days after pairing with nonexposed male and during 3–4 days after pairing. Three characteristics of Drosophila fitness were assessed in progeny of exposed females: fecundity, imago viability, and death rate on pupa stage. Results. The increase of fecundity was revealed only in progeny of waOr flies exposed at early stage of egg development. Imago viability increased only in waOr males. Increase of death rate at the pupa stage in the progeny of exposed females was revealed in lines wa and waC-S. Conclusions. The influence of microwave radiation on Drosophila melanogaster adaptive traits has been studied. In some variants of experiment in progeny of females exposed to microwaves the increase of fecundity, imago viability, and pupae death rate were observed. It is shown that the main factor determining the fitness quantity traits is genotype. The increase of fecundity and imago viability was observed only in one line (waOr) if females exposed to microwaves at early stage of egg development (stage of meiosis). Keywords: fecundity, drosophila, electromagnetic radiation.
