Experimental Evaluation of Effects of Electromagnetic Radiation of Extremely High Frequency on the Developing Organism

Abstract

Introduction: The article is devoted to the results of an experimental study of the variability of indicators of the signs of different levels of importance (population, organismal, and molecular genetic) in order to assess the impact of electromagnetic radiation of extremely high frequency (EHF EMR) as one of the physical environmental factors affecting the human body. Materials and methods: The studies were carried out on the laboratory population of Drosophila melanogaster of the wild phenotype line (D-32). The fruit flies were grown in a standard nutrient medium in special vessels at the temperature of 24.0 ± 0.1 °C in a ТС-80М thermostat subject to the necessary conditions. Results: The model genetic object revealed the effects of the factor that determined the patterns of variability of the number of individuals in the population, their body weight and the RNA content in the body depending on the dose of EHF EMR under different forms of its regulation: at the level of functional asymmetry and in the genotype-medium context. Conclusions: It was demonstrated that radiation of extremely high frequency as a factor of natural and anthropogenic origin influencing vital signs of a developing organism requires attention in a comprehensive hygienic assessment of health effects of environmental factors. This approach is necessary in view of the modifying effect of EHF EMR with respect to the viability of individuals reflecting the morphophysiological and molecular genetic state of the parent generation and its offspring.
