Abstract

Category: Experimental Biology Tags: microwave radiation, electromagnetic fields, stress response, mice, hematopoietic system, adaptation, bioeffects DOI: 10.1134/s1062359024701802 URL: link.springer.com Overview This study investigated how exposure to low-intensity microwave radiation affects the blood system and immune-related organs in mice. Researchers examined several physiological indicators, including: - Number of myelokaryocytes (bone marrow cells) in the femur 🦴 - Level of colony-forming units-spleen (CFU-S) in exo and endotests 🔬 - Hemolytic resistance of erythrocytes 🧬 - Mass and cellularity of the thymus 🫀 Mice were exposed to monochromatic pulsed electromagnetic fields in the 2.27-2.78 GHz frequency range, with an average power flux density of 60 μW/cm² and doses ranging from 0.086 to 0.86 J/g. Findings The study found that repeated exposure to electromagnetic fields caused cumulative biological effects. These effects led to the development of a "stress-like" adaptive reaction in the animals, as reflected by changes in the measured blood system and immune organ indicators. Conclusion The experiments demonstrate that repeated low-intensity microwave radiation induces stress reactions and physiological adaptation in mice. The connection between electromagnetic field exposure and biological stress responses highlights the importance of continued research into EMF-related health risks and mechanisms of adaptation.
