초록

알코올성 간손상을 유발한 마우스 모델에서 새싹인삼 지상부 추출물(HGE)의 간 보호 효과를 확인하였다. 알코올성 간손상 모델은 25% 알코올을 마우스에 5 g/kg의 농도로 경구 투여하여이루어졌고, HGE를 투여한 군에는 알코올을 투여하기 3일전부터 경구투여를 시작하여 10일간 마우스 개체 당 4와 12 mg/kg 의 농도로 경구투여 하였다. HGE를 투여한 그룹에서는 알코올만 처리한 대조군에 비해 AST 및 ALT 수치가 농도의존적으로낮아진 것을 확인하였다. 또한, 간손상에 의해 증가된 LDH 수치는 대조군과 유사하게 감소하였다. 새싹인삼 지상부 추출물로부터 ginsenoside F5, F3, F1, 및 F2의 정량분석 결과는 각각2.5, 4.4, 1.4, 및 23.3 mg/g으로 확인하였다.

영어초록

We studied the effects of the extract of aerial parts of hydroponically cultured ginseng (HGE) on alcohol-induced liver damage (AILD) in mice. AILD was induced by the oral administration of ethanol (EtOH) (25%; 5 g/kg body weight) for seven days in the study as well as EtOH-only groups. However, HGE (4 and 12 mg/kg) was orally administered (once daily for ten consecutive days) only to the study group, three days prior to the EtOH treatment. The HGE-treated group showed significantly lower levels of alanine aminotransferase and aspartate aminotransferase than the EtOH-only group. In addition, HGE administration decreased the level of serum lactate dehydrogenase, a known marker of liver damage. The effect of HGE on AILD was found to be dose dependent, and the consecutive administration of HGE showed no side effects in mice. Our study indicates that HGE treatment can potentially reduce oxidative stress and toxicity in the liver of alcohol-treated mice and that HGE can be a useful therapeutic agent for alcohol-induced hepatotoxicity. Additionally, a simple and efficient high-performance liquid chromatography-ultraviolet detection method was developed for determining the contents of four major ginsenosides in HGE.
The aerial parts of hydroponically cultured ginseng were extracted using 70% fermented ethanol, and the contents of ginsenosides F5, F3, F1, and F2 in HGE were found to be 2.5, 4.4, 1.4, and 23.3 mg/g, respectively
