Immunohistochemical staining of horizontal nerve sections distal to the silicone tube conduit with MBP/DAPI. There was a significant increase in myelination in NH2-GO and Fr + NH2-GO marked by increased intensity of the fluorescent marker. The intensity of MBP positive area in the photomicrographs was analyzed using one-way ANOVA and Tukey test multiple comparison. (*=0.005<p value<0.05, **= 0.0005<p value<0.005, ***= 0.0001<p value<0.0005, ****=p value<0.0001)
