Dexamethasone Enhanced Functional Recovery after Sciatic Nerve Crush Injury in Rats

Figure 4

Effects of dexamethasone on mean density of GAP-43. ((a)–(d)) Immunohistochemical staining of nerve tissue on day 28 after surgery (magnification, 400x). (a) Control group; ((b)–(d)) 0.5, 1, and 2 mg/kg dexamethasone-treated groups, respectively. Data in the sham group are not shown. (e) Mean density of GAP-43 at each time point after surgery. The values represent means ± SD for 6 rats per group. Significant difference compared to control, .
