초록

천연 생리활성 물질 탐색 연구의 일환으로 삼백초로부터 위염 억제 물질을 추출하여 효능을 검정하였다. 삼백초 추출물 0.25~2 g/kg B.W.를 마우스에 경구 투여한 결과 1.5 g/kg B.W. 미만 투여량의 급성독성 실험에서 안정성을 나타내었으며 $LD_{50}$은 1.81 g/kg B.W.였다. 삼백초 추출물 0.5 g/kg B.W.를 마우스에 경구 투여한 만성독성 실험에서는 13주간의 투여기간 동안 독성이 없는 것으로 나타났다. 위염을 유발시키기 전에 삼백초 추출물을 250 및 500 mg/kg B.W. 농도로 미리 섭취시킨 결과 위출혈 및 위부종과 세포손상이 농도 의존적으로 감소하였다. 또한 사이토카인의 발현도 억제되었다. 따라서 삼백초 추출물은 스트레스성 위염에 의한 출혈 및 세포손상을 농도 의존적으로 억제하는 효과가 있으며, 그 mechanism은 염증성 사이토카인의 발현 억제에 의한 것이라 생각되었다.

In this study, gastritis inhibitory substance was ethanol-extracted from Saururus chinensis in order to examine the effect as a part of natural bioactive substance research. In an oral administration experiment, S. chinensis was administered at doses of 0.25 g/kg B.W. to 2 g/kg B.W., resulting in stabilization at 1.5 g/kg B.W. and an $LD_{50}$ of 1.81 g/kg B.W. In a chronic toxicity experiment, 0.5 g/kg B.W. of S. chinensis was administered for 13 weeks, but toxicity was not observed. S. chinensis ethanol-extracts were administered at a concentration of 250 or 500 mg/kg B.W. before induction of gastritis. Gastrorrhagia, stomach edema, cytokine production, and cell damage were reduced in a concentration-dependent manner. Therefore, S. chinensis ethanol extracts inhibit cell damage by stress-induced hemorrhagic gastritis in a concentration-dependent manner via inhibition of cytokine expression.
