Oxidative stress in colitis mice. Antioxidase activity level of colon and serum in the experiment of UC developing and UC self-healing (n = 6, \(\overline{x }\) ± s). T-SOD (a), GSH-PX activities (b), MDA content (c) and CAT activity (d) in colon in turn; T-SOD (e), GSH-PX activities (f), MDA content (g) in serum in turn. In vivo detection of ROS luminous flux in mice abdominal in the experiment of UC developing (h) (n = 3, \(\overline{x }\) ± s). *p < 0.05, **p < 0.01, compared with CT group; ##P < 0.01, compared with DSS group; ΔP < 0.05, ΔΔP < 0.01, comparison between two groups indicated
