The concentration of adrenocorticotropic hormone (ACTH) (A), plasma corticosterone (CORT) (B), and interleukin 1 beta (IL1B) (C) in plasma isolated from trunk blood of rats that underwent crowding stress (CS) for 3, 7, or 14 days. Bars represent ACTH, CORT, and IL1B concentrations 1 h after the transfer of rats into separate cages and refer to the levels assessed between 1:00 am and 2:00 pm. # p < 0.05 vs. CS 3d (LSD test); ^ p < 0.05 vs. CS 7d (LSD test). n = 16–20/group, as indicated in the graphs.
