“…In previous (in vitro) experiments (Ayrapetyan et al, 2009), it was showed that influence both the direct NT effect of MMW and PS pretreated by NT effect MMW have the same modulating effect on heart muscle contractility of snails. On the basis of this data the cell bathing aqua medium was suggested as a target through which the NT biological effect of MMW is realized.…”

Non thermal (NT) effect of direct radiation 4 Hz-modulated 90-160 GHz of Millimeter Waves (MMW) and preliminary MMW-treated physiological solution (PS) influence were studied on snail isolated neuron, rat's brain tissue hydration and skin penetration. It was shown that the 4 Hz-modulated low intensity 90-160 GHz MMW direct radiation and MMW-treated PS leads to on single neuron shrinkage, skin and brain tissue dehydration. On the basis of obtained data it was suggested that the cell bathing aqua medium serve as a target through which the NT effect of MMW on cell hydration is realized. The MMW-induced brain tissue dehydration can considering as consequence of MMW-induced skin water structural changes leading to unknown messenger formation able to modulate the brain cell hydration. The extrasensitivity of cell hydration to low intensity of MMW radiation allow to recommend cell hydration as a cellular marker for estimation of the NT biological effect of MMW on cells and organisms.

“…Previous studies carried out in our laboratory showed that EMF at frequencies less than 100 Hz has a depressing effect on water conductivity, which is accompanied by the increase in pH as a result of decreasing of CO 2 solubility (Stepanyan et al 1999;Akopyan and Ayrapetyan 2005). It was also shown that 4-Hz EMF and 4-Hz-modulated MMW treatment essentially changes the physicochemical properties of PS (Ayrapetyan et al 2009a), having modulating effect on snail neuron membrane's chemosensitivity (Ayrapetyan et al 2004).…”

The effects of extremely low-frequency electromagnetic field (ELF EMF) and ELF-modulated millimeter waves (MMW) on physicochemical properties of physiological solution (PS) at different environmental medium were studied. The existence of frequency ''windows'' at 4 Hz and 8 Hz frequencies of ELF EMF and ELF-modulated MMW which have different effects on heat fusion period (HFP), hydrogen peroxide (H 2 O 2 ) formation and oxygen (O 2 ) content of water solution and different dependency on temperature, background radiation (BGR) and illumination was shown. The obtained data allow us to suggest that cell bathing medium serving as a target through which the biological effects of ELF EMF and ELF-modulated MMW on cells are realized is extra sensitive to environmental factors. Therefore, the variability of experimental data on EMF biological effects, obtained in different laboratories can be explained by different environmental conditions of experiments, which very often are not considered adequately.

The effects of dark -(Ev=0 lux) and low-background radiation (BGR), where R<1μRongen/h, on physicochemical properties (specific electrical conductivity, heat fusion, hydrogen peroxide (H2O2), and oxygen contents) of distilled water (DW) and physiological solution (PS) at 4°C and 18°C were studied. The incubation of DW and PS samples in dark and in low BGR (under dark) medium at 4°C and 18°C brings to changes of their physicochemical properties compared with DW and PS samples incubated in light and normal BGR condition (Ev=500-550 lux and R=17 μRoentgen/h). The observed changes of DW and PS properties depended on their initial temperature, density and ionic composition. It is suggested that water molecules dissociation and ions hydration are sensitive to illumination and BGR. Therefore, the cell-bathing medium can be considered as a messenger through which direct and non direct (by modulating of others factors-induced effects) influences of illumination and BGR on cell metabolism are realized.
