(A): Lung, liver and spleen MPO levels (expressed as milliunits [mU]/gram tissue) and (B): lung, liver and spleen MDA levels (expressed as μM/gram tissue) are shown in sham mice (not subjected to CLP) (“Sham”), in vehicle-treated mice subjected to CLP for 24 hours (“CLP”) and in mice subjected to CLP in the presence of various doses of olaparib (“CLP Olaparib 1 mg/kg”, CLP Olaparib 3 mg/kg” and “CLP Olaparib 10 mg/kg”). Data are shown as mean ± SEM of 10 animals for each group; *p<0.05 shows significant increase in MPO in response to CLP, compared to the sham group; #p<0.05 shows significant protective effect of olaparib in CLP mice compared to vehicle-treated CLP mice.
