Chinchilla rabbits (males 2-2.5 kg) were exposed to 460 MHz RF (CW) for 6 minutes/day for 10 days. Exposure was given to a region proximal to the hypothalamus (19.5 W/kg), adrenal glands (6.2 W/kg), thyroid gland (20.8 W/kg), or the thymus (9.3 W/kg) using a 40 mm diameter contact applicator. The authors concluded from an analysis of membrane changes and chromatin that exposure of the hypothalamus and adrenal glands resulted in a decreased activity of thymocytes while exposure to the thymus itself resulted in a stimulation of thymocytes. In a similar study, rabbits were exposed at the level of the temporo- parietal region of the brain as above. Exposure resulted in a decrease in T-lymphocyte activity, short term serum Ig level changes, decreased thyroid function, increased T4 and TSH levels, and an increase in testosterone and 11-hydroxycorticosteroid levels. The authors suggest that exposure activated the hypothalamo-hypophyseo-adrenal system resulting in increased adrenal cortex and decreased thyroid function. |
