Aim To study the effect of the Kangfuxin liquid on 2,4,6-trinitrobenzene sulfonic acid (TNBS) induced ulcerative colitis in rats, and to explore its mechanism. Methods Male SD rats were divided into normal control, model control, SASP groups, and Kangfuxin low,medium and high dose groups. In ad-dition to the normal control group, other groups were induced ulcerative colitis with TNBS solution. Disease activity index (DAI), organ index, colon mucosa damage index (CMDI) and histopathological score (HS),the expression levels of IL-4, IL-17 in serum, and MPO, EGF, TGF-β1 in colonic mucosa were de-termined. Results The DAI score showed that the model was successful. Compared with the normal group,the level of IL-4 and IL-17, EGF and TGF-β1 in the model group were reduced significantly, while the CMDI score,HS score,colon index and MPO were elevated significantly. The DAI, CMDI, HS and MPO were reduced (P<0.05 or P<0.01), and the levels of IL-4, IL-17, EGF and TGF-β1 increased signifi-cantly(P <0.01). Conclusions Kangfuxin liquid can effectively alleviate ulcerative colitis induced by TNBS in rats. The mechanism may be related to the down-regulation of MPO expression and up-regulation of IL-4,IL-17,EGF and TGF-β1 levels.
