Effects of QDP on mortality a body weight change; b disease activity index; c and colon length; and d of mice with DSS-induced colitis. Colitis was induced in all groups except control group. QDP and SASP were administered to mice from day 6 to 12. The change in body weight was taken as the difference between the body weight before induction of colitis and that immediately before sacrifice on day 13. Disease activity index was determined by combining scores of (1) body weight loss; (2) stool consistency; and (3) stool blood. On day 13, mice were sacrificed, and colon length was measured. Survival data of challenged mice were collected from 9 to 10 mice respectively, and other data were expressed as mean ± SD (n = 7–9). ^### P < 0.001, compared with control group; *P < 0.05, **P < 0.01 and ***P < 0.001, compared with DSS model group
