In this paper I endeavored to show that respiratory sinus arrhythmia closely corresponds with the perception of psychosomatic complaints. To achieve this aim, two groups of menopausal women, each consisting of 85 subjects, were compared, one of which exhibiting troubles with falling asleep, frequent awakening at night, and sweating and fatigability sensations during the day and the other being asymptomatic. Comparative non-invasive biometric analysis included the following: total, inspiratory, and expiratory heart rate, breathing rate, and respiratory sinus arrhythmia. Overall, I found that the respiratory sinus arrhythmia and heart and breathing rates were substantially greater in women with psychosomatic complaints. In this group, the cardiorespiratory indices were further enhanced following exposure to extremely-low-frequency magnetic fields. The study suggests the predominance of sympathetic aspects of the autonomic nervous system as a result of psychosomatic complaints in menopausal women and calls for a caution in using the extremely-low-frequency magnetic stimulation in such women, which may exacerbate untoward heart and respiratory responses.

The aim of this study was the evaluation of the influence of extremely low-frequency magnetic fields (ELF-MF) on the morphology of thyroid epithelial cells in female rats. The rats were exposed to ELF–MF (frequency: 5-10 Hz, induction 10 mT), 1 hour daily for 7 days over a week for 4 months. Control animals were sham exposed. After that time the rats were sacrificed by anaesthetizing with Ketamine and decapitated. The animals’ thyroid glands were extracted. They served as microscopic preparations. In the preparations, the thyreocytes, nuclei, nucleoli and nucleo-cytoplasmatic ratio were evaluated. We concluded that changes in the location of nuclei, surface field, the number and surface of nucleoli and nucloli organizers show an increase in reply activity in the nuclei of thyreocytes and a probable increase of DNA synthesis.
