Some Aspects of the Person Ecological Safety in the Conditions of Chronic Electromagnetic Fields Impulses Influence

Abstract

In an experiment performed on white laboratory rats males with an initial age of 4 months, the dynamics of the mitotic activity of the epithelial cells of the jejunum mucosa crypts after 5, 7 and 10 months of exposure of an electromagnetic field impulses with a density of induced currents of 0.37; 0.7; 0.8; 2.7 kA/m2 and pulse frequency of 50, 100 and 500 per week regardless of their fractionality was considered. The purpose of the study of individual cellular responses is not only to identify the most sensitive components of the system, but also to determine the target organs in order to increase the effectiveness of protective measures for the environmental safety of humans from electromagnetic damage. Having analyzed the obtained data, it should be noted that in the conditions of application of electromagnetic field impulses influence in the studied parameters, sensitivity of undifferentiated epitheliocytes of crypts was found and the multidirectional effect which depended on frequency and density of the induced currents was observed, and their increase in the damage to the jejunum mucosa epithelium amplified due to decrease in mitotic activity, with increase in coefficient of affection in chronodynamics, for a number of parameters, experimentally confirming belonging of impulses of the electromagnetic field to bioeffective ecological factors.
