The levels of IL-6, BDNF and β-EP in serum and brains of CUMS rats in different group during the experiment. Serum IL-6 (a), BDNF (b) and β-EP (c) were detected on 0, 6th and 12th weeks. The concentration of those three indicators in brains was tested at the end of the experiment (d). The results are presented as the mean ± SD (n = 8). aP < 0.05 compared with Control group; bP < 0.05 compared with CUMS group; cP < 0.05 compared with CUMS + CIT group
