Artificial atmospheric ionization acts on rat thyroid gland, but results are depending on treatment polarity: After negative aero-ionization, thyroid gland shows signs of high activity (increased area of follicular epithelium, increased volume of epithelial cell nucleus, and resorption of follicular colloidal material). On the contrary, after positive aero-ionization, hypothyroidism symptoms may be observed, however these signs are less distinct and less homogeneous than signs of activity reported after negative treatment. The simultaneous modifications of serotonemia would be able to partially explain these results.
