초록
Objectives : This study was carried out to investigate the effects of Doche-tang on colonic mucosal ulcer induced by dextran sulfate sodium(DSS). Method : The group was divided into three. The normal group consisted of mice that were not inflammation-induced. The control group was composed of untreated colitis elicited mice. The sample group was administered Doche-tang after colitis elicitation. The effects on colonic mucosal ulcers were evaluated by the morphological change of colonic mucosa, the anti-oxidant effect, HSP 70, NF-κB, COX-1, COX-2 and iNOS. Results : In terms of immunohistochemical findings, the distribution of COX-1 in mice treated with Doche-tang noticeably increased more than that in the control group. The distribution of HSP70, NF-κB, COX-2, iNOS in mice treated with Doche-tang decreased more than that in the control group. Regeneration of surface epithelial cell and goblet cell in mucosa was observed by transmission electron microscope. Conclusion : According to the results, Doche-tang is practicable treatment for colonic mucosal ulcer.
