Figure 5.
Oxidative stress is increased by critical limb ischemia and exercise. Production of free radicals (A) was increased in ischemic muscles (n = 10) compared to control muscles (n = 10) in the non-exercised group. DHE staining (B) showed higher fluorescence in ischemic muscles compared to control muscles (a, Control limb; b, Ischemic limb) in the non-exercised group. Production of free radicals was increased in the exercised group compared to the non-exercised group (A). Exercice showed higher fluorescence (B) in control and ischemic limbs (c, Control limb + exercise; d, Ischemic limb + exercise). *p < 0.05; **p < 0.01.
