Hydrogen peroxide formation and lipid peroxidation: a Serum analyses after intestinal I/R injury reveals only a slight increase of H2O2 serum concentrations and there is a tendency of RIPC-mediated reduction of H2O2 serum concentration in the intestinal ischemia and sham-operated groups. b Serum concentrations of malondialdehyde (MDA) as a marker of lipid peroxidation are not changed after I/R injury or RIPC. Columns show the mean of 5–10 independent experiments. Bars denote SD. *P < 0.05
