Abstract:
Introduction. The nature of a cellphone electromagnetic radiation (EMP) influence on the neutrophils in vitro activation was studied. The relevance of studying the impact of mobile communications and their effects on the body’s physiological processes is determined by the global prevalence of such tools and the research data inconsistency in the both domestic and foreign scientific literature. Material and methods. The object of the study was the whole venous blood samples and isolated neutrophils from 36 adult donors (aged from 22 to 65 years) of both genders. The responses of the neutrophils’ phagocytic activity and its registration were carried out in a flat-bottomed plate for enzyme-linked immunosorbent assay (ELISA), the daily culture of S. aureus ATCC 6538 (strain 209) was used as an inducer of phagocytosis. The intensity of phagocytosis was evaluated by changing the activity of myeloperoxidase (MPO) spectrophotometric method in our modification. Results. In the course of studies of the EMR impact of a cellphone on phagocytic neutrophils, the following was revealed: when culturing neutrophils without the addition of S. aureus, there was a tendency to increase spontaneous MPO activity (by 69%), i.e. its production in the absence of a stimulating factor and, conversely, a significant decrease in the enzyme activity induced by S. aureus (by 34%, p 〈 0.05), i.e. the phagocytic activity of neutrophils. Conclusion We revealed the biological effect of the cellphone EMR as an increase in the spontaneous activity of MPO and a decrease in the bacterially induced activity of the enzyme may indicate a decline in the phagocytic activity of the main cells of the immune system, therefore, it demonstrates a weakening of the protective properties of the human body against infectious diseases. In previous studies, we have shown the presence of the impact of cellphone EMR on the activation of lymphocytes in vitro. The use of immunological tests can be a promising direction in assessing the impact of the cellphone EMR on the human body.
