Effect of polyethylene glycol (PEG)-SOD on Nav current density in muscle afferent DRG neurons. A: representative Nav current recording showing that PEG-SOD (50 U/ml) decreased the Nav current in a medium-sized muscle afferent DRG neuron. B: current density-voltage curves showing the effect of PEG-SOD (50 U/ml) on the Nav current in small and medium-sized muscle afferent DRG neurons (n = 14: 7 for small neurons and 7 for medium-sized neurons) from normal rats. C and D: mean data showing the effect of PEG-SOD (50 U/ml) on the Nav current in different subtypes of muscle afferent DRG neurons (small vs. medium-sized, n = 7 for small and 7 for medium-sized neurons; IB4-positive vs. IB4-negative, n = 8 for IB4-positive and 6 for IB4-negative neurons). Values are means ± SE. *P < 0.05 vs. Control.
