Effects of GalR2 antagonist M871 on the galanin-induced antinociception in NAc of CCI rats. a HWL of the left hind paw; b HWL of the right hind paw. c HWT of the left hind paw; d HWT of the right hind paw. 0.5 nmol galanin was bilaterally injected into NAc of CCI rats at 0 min, and 1 nmol M871 or 1 μl of acetonitrile as a control was bilaterally injected into NAc of CCI rats at 5 min. The data are presented as the mean ± SEM. *: Represents the overall difference between galanin + M871 group and galanin + acetonitrile group; #: Represents the difference between galanin + M871 group and galanin + acetonitrile group at each time point. ^#, *P < 0.05, ^##, **P < 0.01, ^###, ***P < 0.001 compared with the acetonitrile group
