title: [Responses of hypophyseal-adrenocortical system to stressor during repeated stress].
abstract: The corticosterone concentrations were determined in the blood of unrestrained rats exposed to 7 successive trials with 30-min. intervals. This study revealed that hormonal responses of the pituitary-adrenocortical system to stress were decreased, whereas the time of the system recovery was reduced after re-exposure to electric shock. The change seems to be dependent on the strength of the stress agent and the number of re-exposures.
