Oxidative stress, inflammation and cell apoptosis after H/R and II/R injury in vivo and in vitro. (A–B) The levels of MDA, MPO and T‐SOD in intestinal tissues of rats and mice after II/R injury (n = 8). (C) The mRNA levels of IL‐1β, TNF‐α and ICAM‐1 in vitro and in vivo (n = 5). (D) Cell apoptosis after H/R and II/R injury in vivo and in vitro based on TUNEL assay (n = 5). All data are expressed as the mean ± SD. *
P < 0.05, significantly different from control group; #
P < 0.05, significantly different from the 60 min reoxygenation or 90 min reperfusion group.
