Oral application of BLA depresses the activation of glial cells in the spinal dorsal horn induced by L5 SNL and morphine. (a)–(j): Confocal images show OX-42 and GFAP expression in the ipsilateral spinal dorsal horn in different groups as indicated. (m) Quantification of OX-42 and GFAP immunofluorescence in different groups are shown. n = 5 rats in each group, three images per animal. *P < 0.05, **P < 0.01, ***P < 0.001, one-way analysis of variance (ANOVA) followed by a Tukey post hoc test.
