Summary
Aim. The aim of this research was to evaluate the influence of extremely low-frequency magnetic fields on the morphology of thyroid epithelial cells in female rats.
Material and method. 24 female Wistar rats, Hannover substrain, aged 10 months, weighing 300+/-50 g each were included in the experiment. The rats were divided into 2 groups: group ”40”, exposed to extremely low-frequency magnetic fields of frequency 40 Hz; and control group ”C” with sham exposure.
Results. In the preparations, the thyrocytes, nuclei and nuclear-cytoplasmic ratio were evaluated.
Conclusions. The obtained results suggest that the cause of change in morphology of the epithelium of thyrocytes was stimulation of the metabolism with the activity of extremely low-frequency magnetic fields.
