Radiosensitivity of morphoenzymological structural elements of the jejunum mucous membrane in chronodynamics of the impact of electromagnetic fields impulses

Abstract

Results of numerous researches have revealed that most sensitive to electromagnetic radiations are the nervous, endocrine and cardiovascular systems of an organism, however, the analysis of literary data confirms also the direct involvement of organs of the intestinal system in physiological, and not seldom, and the pathological program of the response of an organism to the action of extreme factors. In the experiment executed on white laboratory male rats by ourselves there was studied the grade of the radiosensitivity of morphoenzymological structural elements of jejunum mucous membrane after 5, 7 and 10 months of chronic influence of electromagnetic fields impulses with a density of induced currents 0.37; 0.7; 0.8; 2.7 kA/m and frequency of impulses 50, 100 and 500 in a week irrespective of their divisibility of ultrashort duration of 15 a 40 ns. Scientific value and novelty of results is concluded in revealed multiple linear relationships between indices of electromagneticfields (duration of the impact, density of induced currents, periodicity of impulses and the dynamics of the studied indices of a morphofunctional condition of a jejunum mucous membrane). Besides that, there was found the critical population to indices of electromagneticfields impulses parameters - the jejunum mast cells differing in hypersensitivity and dependence on duration of influence and density of induced currents revealed, at that their bioeffects were unidirectional.
