A Study of the Effectiveness of Hwanggeum-tang and Gamchosasim-tang in the Mice Model of Inflammatory Bowel Disease

Abstract

Objectives: This study investigates the mechanism of Hwanggeum-tang (HGT) and Gamchosasim-tang (GST) on inflammatory bowel disease (IBD).Methods: The mice (C57BL/6N) were treated with distilled water and 3% dextran sulfate sodium (DSS) to experimentally induce ulcerative colitis. The mice were divided into 7 groups of (6 mice: normal, negative control, positive control (with sulfasalazine), 4 experimental groups (with HGT and GST, respectively). RAW 264.7 cells were used for cell experiments. The experiment was conducted in two ways: in vitro and in vivo.Results: In the experimental group (HGT, GST) of in vitro experiments, NO production decreased, and significant changes in gene expression and protein activation were observed.<br/>The length of the colon recovered in the experimental groups (HGT, GST) of the in vivo experiment was longer than that of the negative control group, and the mucosal barrier was recovered. Sone significant changes in the amount of mRNA expression were partially observed, and significant changes in protein activation also were confirmed.Conclusions: HGT and GST are effective in treating IBD caused by DSS. In the same herbal preparation group, the higher the concentration, the better the experimental effect, and when the same concentration was tested, HGT was more effective than GST. Herbal medicine has a higher antioxidant effect than sulfasalazine, so it is also excellent for cell protection.
