PNS administration promoted BDNF protein levels in the serum of ME rats. Expression level of BDNF was measured by ELISA and data were presented as means ± standard deviation, n = 8 in sham and ME, n = 7 in other groups. *p < 0.05, **p < 0.01 versus Sham group; # p < 0.05, ## p < 0.01 versus ME group.
