For tissue level homogenate oxidative stress markers (MDA and MPO), there were highly significant increases in the colitis group (7.47±1.21 ng/ml and 250.4±30.27 pg/ml, respectively) compared to the healthy control group (1.37±0.39 ng/ml and 105.70±19.70 pg/ml, respectively). This evidence concerns the gene MPO and colitis.
