Different Levels

Despite the fact that there are still conflicting opinions about the damage caused by modern wireless communication technologies, most scientists report on the negative biological effects of low-intensity radio frequency electromagnetic radiation at different levels of the organization of live nature. There is no doubt that there is a need not only for a sanitary and hygienic assessment of man-made electromagnetic effects on humans, but also for an environmental assessment for biota. The purpose of the study was to assess the potential environmental risk of electromagnetic impact in the centimeter range on natural ecosystems. The initial data were the authors' own results in the field of radiobiology of non-ionizing radiation, as well as published of other researchers. The article analyzes the biological effects of radio frequency electromagnetic fields detected in organisms of different systematic groups and levels of organization. The data on the non-thermal biological effects of electromagnetic fields indicate a high sensitivity of different species to this factor. The analyzed research results emphasize the need to take into account the features of non-thermal effects of electromagnetic radiation on biota, since these radiations can have a negative impact on different hierarchical levels in natural ecosystems.

Introduction. There is still an open question about the limits of medical use of low-intensity electromagnetic radiation of the optical range in tumor growth due to the risk of increased proliferation of tumor cells. The conditions under which the tumor process is stimulated, as well as the mechanisms of photobiomodulation in oncological pathology, remain unclear. The aim of the study - in vitro evaluation and comparison of the effect of low-intensity electromagnetic radiation with wavelengths of 400, 460 and 660 nm on the activity of free-radical processes in tumor tissue and blood in normal and growing experimental neoplasia. Materials and methods. The study was conducted on biological material obtained from white non-linear rats intact and with subcutaneously transplanted cholangiocellular cancer MS-1. The sources of low-intensity radiation with wavelengths of 400, 460 and 660 nm were led generators. The content of hemoglobin, the activity of superoxide dismutase and catalase, changes in the overall level of free radical processes and antioxidant activity by induced chemiluminescence, and DNA damage by the method of DNA comets were studied. Data analysis was performed using nonparametric statistics methods. Results. The multidirectional effect of radiation with wavelengths of 400, 460 and 660 nm on free-radical homeostasis indicators at the early and late stages of tumor growth, as well as the dependence of biological effects on the wavelength of radiation, was found. Conclusions. The results obtained allow making a number of assumptions about the mechanisms of action of the optical electromagnetic waves on tumor growth, modulating free radical processes in the tumor-bearing organism.
