[The effect of eating behavior on the circadian rhythm of plasma corticosterone in growing rats]. 1977

C Obled, and M Arnal, and J Grizard

The circadian rhythm of plasma corticosterone was studied in growing Rats fed on an ad libitum or controlled feeding schedule (six meals per day). Circadian plasma corticosterone rhythm was conventional in ad libitum Rats. Increases of circulating hormone occurred during the last light hours and the first dark hours. Plasma corticosterone rhythm was modified by controlled feeding. Meal feeders exhibited a high value during the last light hours and a secondary hump at midnight. Feeding schedule was not the main synchronizing factor in rat circadian corticosterone rhythm.
