Immunohistochemical staining for CD11b in the liver sections of the normothermia (NT; A-E) and hypothermia (HT; a-e) groups at sham, 6 h, 12 h, 1 day, and 2 days after asphyxial cardiac arrest (ACA). CD11b immunoreactivity is significantly increased and peak at 1 day after ACA in both NT-CA and HT-CA groups, but CD11b immunoreactivity is significantly lower in the HT-CA group than those in the corresponding NT-CA group at all point in times after ACA. CV: central vein. Scale bar = 50 μm. (F) Relative optical density (ROD) of CD11b immunoreactivity in the normothermia and hypothermia groups (n = 5 at each point in time after sham-operation, n = 11 at each point in time after ACA, ^*P < 0.05, significantly different from sham group; ^†P < 0.05; significantly different from previous time-point group; ^#P < 0.05, significantly different from NT-CA group). Bars indicate means ± standard error of the mean
