Comparison of: NOX (A) and XO (B) activity between colorectal cancer tissue (n = 29) and normal mucosa (n = 29); NOX activity (C) between adenocarcinoma and mucinous adenocarcinoma; XO activity (D) depending on the intensity of inflammatory infiltration in the invasive front of the tumour; XO activity (E) between colorectal tissue with and without vascular invasion. The data are presented as median (minimum–maximum). Abbreviations: NOX—NADPH oxidase, XO—xanthine oxidase. * p < 0.05, ** p < 0.01.
