Chronic exposure to electromagnetic fields: Effects on thyroid parafollicular cells in rats

Abstract

Based on the presented results and the previous data on thyroid follicles, it could be concluded that (i) PF cells and follicular cells reacted to EMF exposure similarly by their decreased activity, (ii) PF cells are the endocrine cell 'population' in the thyroid less susceptible to EMFs, and (iii) the activation of PF cells after the first recovery week following EMF exposure indicates a possible moderate involvement of these cells in overall thyroid reaction to certain environmental influences.
