The herbal medicine Dai-Kenchu-To directly stimulates colonic motility.

Abstract

Dai-kenchu-to (DKT) has attracted attention as a drug that improves the symptoms of postoperative ileus. However, the detailed mechanism of its action still remains unknown. The effect of DKT on colonic motility was herein evaluated using an original method. Eight healthy male volunteers who understood the purpose of this study were enrolled. Dai-kenchu-to (5 g) was dissolved in saline and administered into the cecum using a colonoscope until the ascending colon became distended. Colonic motility was observed by extrasomatic ultrasonography for 30 min. Colonic contractions were observed 129.4 (range 110-145) s after DKT administration into the ascending colon. Every segment in the right colon divided by the crescentic folds contracted independently. On the other hand, no colonic contractions were observed in the right colon after saline solution alone was administered to the ascending colon. In conclusion, DKT stimulates colonic motility immediately after administration, in the same manner as it does for the upper alimentary tract.
