Abstract
The 1st phase of the increase began 1 hr. after irradiation and was clearly discernable after 2.5 hr. Following a temporary normalization period, the 2nd larger increase was detectable after 72 hr. The changes in adrenal and blood corticosteroids were parallel; there was no indication of inhibition of adrenal secretions. Ether narcosis increased the corticosteroid level in the blood. Sham irradiation of normal rats caused a significant increase in the corticosteroids of peripheral blood, but not of the adrenal gland. This effect was not found in previously accustomed animals. The results show no indication of a drop in corticosteroids in the blood and adrenal gland after whole body X-ray exposure.
