1. 1. An ultradian rhythm was found in the daily variation of the parameters concerning the peripheral metabolism of corticosterone in sexually mature male Japanese quails. 2. 2. The period of this rhythm was eight hours; three peaks and minima were found in the daily fluctuation of metabolic clearance rata and an antiphysed rhythm in the biological half-life as well as in tetrahydrocorticosterone/corticosterone conversion rata. 3. 3. The findings emphasize the importance of the peripheral metabolism in developing of corticosterone plasma levels; and analyze the circadian rhythm of corticosterone plasma level as a result of secretion rate and peripheral disappearance.
