To investigate the corticosterone response of Japanese quail to an acute hemorrhagic stress (i.e. jugular vein puncture) after a low level 2450 MHZ microwave exposure during the first 12 days of embryogeny (i.e. in ovo).
Two different experiments were carried out.
First: unexposed adult male and female Japanese quail were studied. Hemorrhage resulted in increased plasma corticosteron levels in both sex. The corticosteron level in shams were higher than in controls. The values for total erythrocyte numbers, hematocrit volumes, and mean cell volumes were decreased in response to hemorrhage.
Second: eggs were exposed, after hatching, juvenile males and females were hemorrhaged. Males showed an increased corticosterone level, no effects on females were found.
