EGCG-FMT alleviated oxidative stress and colonic damage better than CON-FMT and EGCG-SFF. Concentrations of T-SOD (a), CAT (b), and MDA (c) in the plasma from each group. Levels of T-AOC (d), T-SOD (e), CAT (f), GSH-px (g), and MDA (h) in the colon (n = 8 per group). i Apoptosis rate in colonic sections (n = 6 per group). j Representative fluorescent pictures of TUNEL staining of colonic sections. Scale bars represent 50 μm. k Representative images of Alcian blue-stained inner mucus layer of colonic sections. Scale bars represent 50 μm. l Representative images for the microstructure of colonic epithelia by TEM. Data were presented as means ± SEM. Statistical significance was determined using one-way ANOVA, followed by Tukey test. *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001
