Abstract

Objectives :We examined the effect of Hwangryunhaedoktang(HH) on the experimental ulcerative colitis induced by dextran sulfate sodium (DSS).
Methods :Experimental colitis was induced in rats by daily treatment with 5% DSS in the drinking water for 5 days. Afterward, the mts were divided into two groups: the control group was administered water and the sample group was administered HH for 7 days.
Results :The sample group provided HH for 7 days demonstrated fast recovery of body weight compared with the control group. Histologic change showed fast regeneration of crypt and surface epithelial cells and decreased edema of the submucosa and decreased lymphatic follicle of mucosa compared with the control group. Immunohistochemical stain usingCOX-2 gene was decreased and there was localized Ki-67 positive reaction. Regeneration of surface epithelial cell and goblet cell in mucosa was observed by transmission electron microscope. These results indicate therapeutic effect of HH on DSS-induced colitis in rats.
