Colon MPO activity (a) and cytokines level of colon (b, c) and serum (d, e) in the experiment of UC developing and UC self-healing (n = 6, \(\overline{x }\) ± s). a–c MPO activity, IL-1β expression and IL-18 expression in colon; d, e, IL-1β and IL-18 expression in serum. *p < 0.05, **p < 0.01, compared with CT group; #P < 0.05, compared with DSS group; ΔP < 0.05, ΔΔP < 0.01, comparison between two groups indicated
