Fig. 2From: Neuropathological changes in dorsal root ganglia induced by pyridoxine in dogsElectrophysiological recording. There were no significant differences in M wave amplitudes (a); however, compared to the before PDX treatment amplitudes, there were significant differences in the H-reflex amplitude at 1 day, 1 week, and 4 weeks after the last PDX treatment (b). **P < 0.05 indicates a significant difference.
