Levels of norepinephrine (NE) and interleukine-6 mRNA (IL-6 mRNA) in the cornu ammonis (CA) and dentate gyrus (DG) in wild-type (white square) and transgenic (SHR72) rats (black square) exposed to a single (1 × 2 h) or repeated (7 × 2 h) immobilization stress (IMO). C control; 6×IMO + 24 h-adapted IMO rats exposed to 6×IMO for 2 h and decapitated 24 h after the last IMO. Each value is the mean ± SEM (n = 5–8). Statistical significance vs. corresponding wild-type group: *P < 0.05; **P < 0.01; statistical significance vs. wild-type control group: ^# P < 0.05; ^## P < 0.01; statistical significance vs. transgenic control group: ⁺ P < 0.05
