Influence on Erythropoiesis and Blood Catalase Activity Low Intensity Electromagnetic Millimeter Radiation

摘要

The present study was undertaken to investigate changes of the blood catalase activity and regeneration processes in the circulatory system of rabbits under conditions of bone-marrow deficiency and long-term exposure to low-power extremely high frequency electromagnetic radiation (EHF EMR) at frequency of 50.3 GHz. As it is known, this frequency is resonant for the vibrations of water hexagonal structures! 1]. During both whole-body and head area exposure to EHF EMR the animals were placed in front of the center of the conical antenna, at distance of 500 mm and 150 mm from the radiating end of the antenna (far field zone). The spatial peak incident power density (IPD) was measured to be as 0,05 mW/cm2 and spatial peak specific absorption rate (SAR) at the skin surface was calculated to be as 2 W/kg.The results of our experiments show that repeated exposures can cause erythrogenetic activity, prolonged retyculocyte crisis, hemoglobin and erytrocyte content growth, as well as faster retyculocyte maturation. The obtained data demonstrate that living organisms react to low-intensity monochromatic radiation mobilizing their internal resources. Namely, regenerative processes are intensified and compensation mechanisms gain broader capacities. Deficiency of bone marrow in the result of its removal does not significantly affect the erythrogenesis. Irradiation on the rabbits head area increases catalase activity in peripheral blood, maximum of which was registered 20-fold and on the 10-th day after 25-fold influences.The character of changes of the catalase activity does not depend on the changes of total number of erythrocytes.The observed activation of catalase probably, promotes the enhancement of the power antioxidant system of the organism.
