Activities (mean + SE) of superoxide dismutase (SOD, units/mg protein), catalase (CAT, μmol H2O2decomposed/min/mg protein) and glutathione peroxidase (GPX, μmol β-NADP oxidized/g protein) in the tumors, livers and colon of groups of mice fed diets containing either 5% CO or 3% FOC and 2% CO with or without 2000 IU Vitamin E/kg diet for two weeks.

a One way ANOVA followed by an SNK multiple comparison test indicated that the mean GPX in the tumors of groups that share a superscript were not significantly different (p < 0.05). There were no other significant differences.
