Figure 3.

Mean number of glial fibrillary acid protein (GFAP) (A) and OX-42 (B) immunopositive cells in DRGs from different surgery groups. (C) and (D) show mean number of GFAP and OX-42 immunopositive cells in spinal nerve, respectively. All DRGs and spinal nerves were harvested 15 days after surgery, except early spinal nerve ligation (SNL) rats that were killed 4 days after the surgery, regardless of behavioral testing results (responders and non-responders). Data are reported as mean (±standard deviation) number of GFAP and OX-42 immunopositive cells counted in the ipsilateral L5 dorsal root ganglion and adjacent spinal nerve. Brackets denote Bonfferoni post-hoc differences between groups.
