Cresyl violet staining of the dorsal root ganglion (DRG) in the control (a), vehicle-treated (Vehicle, b), and nerve growth factor gene-treated (NGF, c) groups at 4 weeks after pyridoxine injection for 1 week. In the control group, cresyl violet positive small- (white arrow), medium- (arrow head), and large-sized (black arrow) neurons are well detected in the DRG. Note that cresyl violet positive cells in the vehicle-treated group are few and some vacuoles are detected, while cresyl violet positive large-sized neurons are also abundant in the NGF group. Scale bar 100 μm. d Relative number as a % of small-, medium-, and large-sized neurons of the control group in the DRG (n = 4 per group; *P < 0.05, significantly different from the control group; # P < 0.05, significantly different from the vehicle group). The bars indicate the mean ± SEM
