To study reactivity to electric footshock, blood levels of cholinesterase and sulfhydryl groups, urinary output of 17-ketosteroids, and deficits of performance in the shuttle box during or after chronic microwave exposure of rats.
|Exposure duration||14 wk (7h/d; 7d/wk)|
Weekly measures of body mass and food intake did not reveal statistically significant effects of microwave exposure. Assessments of threshold for electric-footshock detection revealed a significant difference between microwave and sham-exposed rats. Assessments of cholinesterase and sulfhydryl groups in blood and 17-ketosteroids in urine did not distinguish the two groups of animals. Behavioral measures were made at the end of the 14-week exposure. Statistically significant differences between microwave- and sham-exposed animals were observed for these measures. Examination of adrenal tissue, plasma electrolytes, and organ masses after 14 weeks of irradiation revealed no difference between the two groups of animals.
