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.

The purpose of this experiment is to investigate the feasibility of extracts (sample extract, MSE) mixed with hot - water extracts as health functional nutritional foods for prevention and treatment of liver damage. The experimental method was to investigate the effects of carbon tetrachloride on liver damage in rats by 60% of liver cirrhosis level. The effect of mixed extracts (MSE) was investigated by measuring the physiological functions, biochemical functions, and molecular biologic TGF - ${\beta}$ and P53 levels in liver - injured rats. with MSE doses administered differently(0.50ml, 0.75ml). A total of 30 rats were used for normal group, control group, positive control group, experimental group 1, and experimental group 2. The rats were given 6 times a week for 6 weeks at a fixed time once a day. The results of the experiment were statistically significantly higher in the control group than in the normal group and the positive control group, and statistically significantly lower in the experimental group (1 and 2) than the control group. There were some significant differences in the comparison between the experimental groups (1 and 2), but no significant changes were found. In conclusion, the results of this study are expected to be useful as functional food, and the variation of physiological activity and the degree of liver molecular biotechnology will be used for the research of the same field.
