Light Photomicrographs show immunohistochemical staining of S100ß in dorsal root ganglion neurons of SNT (a) and SNT + HBO treated (b) groups, respectively. The positive staining of S100ß is presented by a brown color of cytoplasm (arrows) (Scale bar = 100 μm). The intensity of the immunohistochemical staining in sensory neurons were decreased after HBO treatment. Densitometry analysis of immunohistochemical photomicrographs for S100ß was assessed (c). Data are expressed as a percentage of total tissue area. ^* P < 0.05 versus SH and SH + HBO groups; ^#P < 0.05 versus SNT group by one-way ANOVA followed by Tuke’s post-hoc tests
