Figure 3. — Immunohistochemical staining for superoxide dismutase 1 (SOD1) in liver sections of normothermia (NT; A-E) and hypithermia (HT; F-J) groups at sham, 6 hours, 12 hours, 1 day, and 2 days after asphyxial cardiac arrest (ACA). SOD1 immunoreactivity decreased after 6 hours post-ACA in the NT/ACA group. SOD1 immunoreactivity was significantly higher in the HT/ACA group than in the NT/ACA group at all times after ACA. CV: central vein. Scale bar=50 µm. (K) Relative optical density (ROD) of SOD1 immunoreactivity in all groups (n=7 at each time after ACA, ^aP<0.05, significantly different from NT/sham group; ^bP<0.05, significantly different from previous time-point group; ^cP<0.05, significantly different from NT/ACA group). Bars indicate means±standard error of the mean.
