Fig. 4.

Transverse sections from each group (a CON, b CON + PP, c HU, d HU + PP) stained with the fluorescent probe dihydroethidium (DHE) that detects oxidative stress. e, f Mean levels of DHE fluorescence (e) and superoxide dismutase 1 (SOD-1) protein expression (f) in the soleus muscle of each group. Scale bar: 50 μm. Values are shown as the mean (bars) ± SEM (error bars). The asterisk (*), dagger (†), and double dagger (‡) indicate a significant difference from the CON, CON + PP, and HU groups, respectively, at P < 0.05. AU Arbitrary units
