In the bet15+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 lower than in the colitis group, while antioxidant enzyme activity values such as GPx were found to be higher (p < 0.001, p < 0.001, p = 0.001, p < 0.001, p < 0.001, p = 0.001, p < 0.001, respectively) (Table 1). The gene discussed is SOD1; the disease is colitis.
