Adrenal and plasma corticosterone changes in continuously irradiated rats. I. The dynamics in the course of irradiation

Abstract

Adrenal and plasma corticosterone concentration changes in the course of 25 day continuous irradiation of rats with a daily dose of 15.48x10/sup -3/ C/kg (60 R) of gamma radiation on an open experimental field were followed. The changes were evaluated by a comparison with control rats kept in the same conditions but protected against the radiation effect. The first increase in adrenal corticosterone occurred after one day of irradiation and the maximal increase occurred after 7 days of irradiation. The changes in plasma were insignificant within this period. After 14 days of irradiation the adrenal corticosterone concentration decreased to a minimum during the whole period but it remained increased as against controls. Plasma corticosterone, however, increased to the maximal values within this period. A second peak of elevated adrenal corticosterone concentration was evident after 21 days of irradiation; the plasma values decreased. Corticosterone tended to decrease down to the level of the control group 25 days after irradiation.
