(A) Adult male F344 rats (n = 5/group) either were exposed to an acute restraint procedure (restraint) or remained in their home cages (no stress). Blood samples were taken after 25 and 100 minutes of restraint. Time-matched blood samples were taken from nonstressed home cage controls (no stress) animals, and eHsp72 was measured. (B) Rats (n = 5/group) either were exposed to 100 minutes of restraint (restraint) or remained in their home cages (no stress). Immediately after restraint, all rats were injected subcutaneously with live E coli (∼2.5 × 109 colony-forming units). Inflammation was measured daily
