Light Photomicrographs show immunohistochemical staining of COX-2 in dorsal root ganglion neurons and anterior horn neurons of the spinal cord in SNT (a and b) and SNT + HBO treated (c and d) groups, respectively The positive staining of COX-2 is presented by a brown color of cytoplasm (arrows) (Scale bar = 100 μm). The intensity of the immunohistochemical staining in sensory and motor neurons were decreased after HBO treatment. Densitometry analysis of immunohistochemical photomicrographs for COX-2 was assessed (e). Data are expressed as a percentage of total tissue area. *** P < 0.001 versus SH and SH + HBO groups; ** P < 0.01 versus SNT group by one-way ANOVA followed by Tukey′s post-hoc tests
