Corticosterone exposure (7 days) produces elevations in CORT and blunts response to dexamethasone. a On the seventh day of CORT exposure (300 μg/ml), plasma CORT levels were significantly higher than the Water group at 10 pm, and significantly lower than the Water group at 10 am (n=8/group). Asterisk signifies significant difference from the Water group (p<0.05). b CORT exposure (300 μg/ml; 7 days) resulted in significantly less suppression of plasma CORT levels in the CORT group after dexamethasone (0.1 mg/kg, SC) administration (blood collected 4 h after dexamethasone administration at 11 am; n=9/group). Asterisk signifies significant difference from the respective vehicle group (p<0.05); number sign signifies significant difference from the respective Water groups. Values on graphs represent mean ± S.E.M.
