In the colitis group, oxidant parameters such as malondialdehyde and myeloperoxidase, antioxidant parameters such as SOD inhibition rate and inflammation markers such as TNF-α, IL-1β and IL-6 were found to be higher than in the control group, while antioxidant enzyme activity values such as catalase and glutathione peroxidase (GPx) were found to be lower (p < 0.001), (Table 1). Here, MPO is linked to colitis.
