(A) Representative photos of Nrf2 staining for sciatic nerve transverse sections of rats (n = 6/group) treated with DMF 15mg/kg (d-f), 45mg/kg (g-i) and methylcellulose-treated animals (a-c), showing an increase of Nrf2 positive cells for 45mg/kg DMF-treated rats. Pictures a, d and g show nuclear stain (DAPI), pictures b, e and h Nrf2 stain and pictures c, f and i indicate double staining. Scale bars indicate 100μm. (B) Percentage of Nrf2 positive staining per sciatic nerve section measured by immunofluorescent staining on day 16 p.i. from EAN rats (n = 6/group) receiving DMF at different doses (15mg/kg, 45mg/kg/day) and methylcellulose-treated rats. Mean values and SEM are depicted (*p<0,05).
