Abstract

The dried rhizomes and roots of Gentiana scabra (GS) have been frequently prescribed as a traditional folk medicine in East Asia (including China, Japan, and Korea) for the treatment of various pathophy-siological conditions, such as inflammatory skin diseases, anorexia, indigestion, gastric infections, and diabetes mellitus. In the present study, the effects of aqueous (GS-W) and ethanolic (GS-E) extracts of GS on gastrointestinal (GI) motor function were investigated by measuring the in vivo gastric emptying rate (GER) and the intestinal transit rate (ITR) in mice. The GER was significantly increased by GS-W at a dose of 1 g/kg. The ITR was significantly increased by GS-W (at doses of 0.1 and 1 g/kg) or GS-E (at a dose of 1 g/kg) in a dose-dependent manner. Furthermore, the ITR value of GS-W (at a dose of 1 g/kg) appeared to be higher than that of cisapride, which was the most prominent prokinetic agent in the 1900s but was removed from the market in 2000 due to its fatal side effects. The above results suggest that GS-W might be a potential prokinetic agent to replace cisapride.

용담(Gentiana scabra)의 근경 및 뿌리를 말린 한약재는 우리나라, 중국, 일본을 포함하는 동아시아 지역에서 아주 오래 전부터 각종 염증성 피부 질환, 소화불량, 식욕부진, 위염, 당뇨병 등의 치료를 목적으로 한의학에서 널리 처방되어 왔다. 본 연구에서는 용담이 위장관 운동 기능에 미치는 영향을 검정하기 위해 용담의 열수 및 에탄올 추출물을 각각 제조하였으며, 마우스에서 in vivo 위 배출 속도 및 위장관 이송률을 측정하는 실험을 수행하였다. 위 배출 속도는 용담 열수 추출물 1 g/kg 투여 시 유의적으로 증가하였다. 위장관 이송률은 용담 열수 추출물 0.1 및 1 g/kg 투여 시, 그리고 용담 에탄올 추출물 1 g/kg 투여 시 유의적으로 증가하였으며, 두 추출물 모두 용량 의존적 증가 양상을 보였다. 더욱이, 용담 열수 추출물 1 g/kg 투여 시의 위장관 이송률은, 1990년대까지 임상에서 가장 강력한 위장관 운동 촉진제로 쓰였으나 2000년 이후 부작용으로 시장에서 철수된 약물인 cisapride 투여 시보다 그 수치가 높았다. 이러한 결과들은 용담 열수 추출물이 잠재적으로 cisapride를 대체할 수 있는 위장관 운동 촉진제로 개발 가능한 후보 물질임을 시사한다.
