Prevention of ischemia-reperfusion damage with polymerized superoxide dismutase.
The efficacy of preventing ischemia-reperfusion damage by employing native or modified (mPEG-SOD) superoxide dismutase in an experimental model of acute ischemia was tested in the left hind limb of 43 Wistar rats. A significative difference (p=0.004) of the survival leg rate was found in the group treated with mPEG-SOD (86.6%) compared with the control group (30%). This difference was confirmed both clinically and by TEM analysis of muscular specimens.
