<p>(A) Representative photos of APP (amyloid precursor protein) staining for sciatic nerve transverse sections of rats (n = 6/group) treated with DMF 15mg/kg (b, e), 45mg/kg (c, f) and methylcellulose-treated animals (a, d), showing an reduction of APP positive cells for DMF-treated rats. Scale bars indicate 100μm for a-c and 50μm for d-f. (B) Mean numbers of APP positive cells per mm<sup>2</sup> sciatic nerve sections as calculated by immunohistochemistry on day 16 p.i. from EAN rats (n = 6/group) receiving orally DMF at different doses (15mg/kg, 45mg/kg/day) and methylcellulose-treated rats. Mean values and SEM are depicted (*p<0,05). The experiment was repeated 2 times with similar results.</p
