The objective of this study was to examine the biochemical parameters of hepatic function such as serum level of ALT (alanine aminotransferase), AST (aspartate aminotransferase), ALP (alkaline phosphatase), LDH (lactate dehydrogenase), and content of TG (triglyceride) and cholesterol, and tissue immunological changes of the $CCl_4$-treated rats with administration of the mixed sample extract (MSE). The liver weight in $CCl_4$-administered experimental control group (EC) was slightly higher than that of normal control (NC) group. Hepatic damage parameters (ALT, AST, ALP, LDH & TG) in serum of the EC group were significantly higher than those in serum of the NC and silymarin-treated positive control (PC) group. On the other hand, these hepatic damage parameters of MSE-treated experimental (E1 & E2) groups were significantly lower than those of EC group. The number of WBC, neutrophils, lymphocytes and platelets, and the contents of hemoglobin, and hematocrit in EC group were significantly higher than those of NC group. However, the number of WBC and lymphocytes in E1 and E2 groups were significantly lower than those of EC group. Also, the collagen developmental areas in the liver of NC and PC groups by hepatic immuno-histological findings were found slightly positive. Whereas, hepatic fibrous developmental tissue of EC group was strongly positive brown color band, those of E1 & E2 groups were decreased. Therefore, it was concluded that the induction of hepatic fibrous tissue activation had a preventive effect of MSE against the $CCl_4$-induced hepatic damage in rats. However, further study is needed in this filed.

This study was conducted to clarify the effects of the Korean raisin (Hovenia dulcis Thunb) extracts and polyherbal extracts consisted of 6 types herbal extracts including HDT (HDTmix) on $CCl_4$ induced organ damages. Extracts were prepared by autoclave ($121^{\circ}C$, 15 psi, 3 hours) and filtered with nylon cloth and filter paper then freezing dried. Male Sprague-Dawley rats $(200^{\circ}{\ae}20g)$ were used as experimental groups, which were divided into 5 groups; intact control group (100 mg/kg), $CCl_4$ dosing group (100 mg/kg), $CCl_4$ dosing after HDT extract dosing group (100 mg/kg), $CCl_4$ dosing after HDTmix dosing group (100 mg/kg), Silymarin dosing group (5 mg/kg) after all test articles were orally dosed once a day for 28 days. They were sacrifiled under ether anesthesia. HDT extracts and HDTmix dramatically inhibits the $CCl_4$ intoxicated hepato/nephropathies with immuno-suppress changes on the spleen. They showed more dramatical protective effects on most of specific organs compared to that of Silymarin 5 mg/kg except for hepatoprotective effects in which, quite similar effects were detected. In addition, HDT extracts showed synergic effects with other types of herbal extracts because HDTmix showed more favorable protective effects on the all specific organs showing $CCl_4-related$ histopathological changes compared to HDT extracts.

본 실험은 건강기능식품의 원료로 이용되고 있는 식품들을 혼합하여 열수 추출한 추출물(시료추출물, MSE)이 간 손상의 예방 및 치료와 관련된 건강기능성 영양식품으로서의 활용 가능성을 확인하고자 사염화탄소에 의한 랫드의 간 손상을 간경화 수준의 60%로 유발시켜 추출 물질의 투여에 따른 간 질환 개선에 미치는 영향을 분석하였다. 혼합수추출물(MSE)의 용량은 군별 다르게 투여 하여(0.50ml, 0.75ml), 간 손상된 랫드에 미치는 생리활성 기능과 생화학적 기능 및 분자생물학적 TGF-${\beta}$, P53을 측정하여 혼합추출물의 투여 후 기능 변화를 분석 하였다. 실험은 정상군, 대조군, 양성대조군, 실험군1, 실험군2 군으로 하여 군당 6마리씩 총 30마리를 이용하였고, 지정된 용량으로 1일 1회 일정한 시간대에 주 6회씩 6주간 적용 후 처치하였으며, 실험 결과는 정상군과 양성대조군에 비하여 대조군에서는 통계적으로 유의성 있게 높았으며, 실험군(1, 2) 에서는 대조군에 비해 통계적으로 유의성 있게 낮아졌으며, 정상군과 양성대조군 비교에서도 실험군과 유사한 결과가 나타났다. 실험군(1, 2) 간 비교에서 유의한 차이는 일부 있었으나 유의성 있는 많은 변화가 나타나지 않았다. 이상의 실험결과를 종합해 보면 기능성 식품으로 활용 가능성이 있을 것으로 판단되고 생리활성 변동과 간 분자생물학적 발현 정도를 동일 분야연구에 활용이 될 것으로 사료 된다.
