The concept of traditional oriental medicine and pharmaceutical and clinical effects were studied on holyessing obtained through carbonization of wood, before practical application. The results were obtained as follows: 1. Holyessing can be thought to be effective fluid to promote physiological metabolism as heat of water(水中之火) in the respest of oriental medicine. 2. Pharmaceutical effects of holyessing were reported to be antidiabetic effect, protective effect on liver, anticancer activity, protective effect against electronic damage, thermic effect, deodouring effect and proetcive action on atrophy dermatitis. 3. Several kinds of holyessing derived from other trees except of oak chiefly used so far had better be studied such as Morus bombycis. 4. Acute and chronic toxicity, combination of holyessing with other food, artifical correction of its taste and concentration should be absolutely studied.

Chlorpyrifos (CPF) is one of the most heavily used organophosphate pesticides and is useful as an insecticide drug. However, CPF also causes toxic effects in nontarget organisms, including humans and animals. Jageum-Jung (JGJ) is a traditional oriental medicine, composed of five specific herbs with antioxidant and hepatoprotective properties, used for detoxification. In the present study, highly concentrated CPF was orally administrated to male Institute of Cancer Research mice to produce acute toxicity, and the protective effects of JGJ administration were investigated through statistical analysis of changes in body and organ weights and serum biochemical parameters. JGJ caused body and organ weights to recover and reduced the levels of serum biochemical parameters indicative of liver damage, such as glutamic oxalate transaminase, glutamic pyruvate transaminase, alkaline phosphatase, lactic dehydrogenase, urea, glucose, total cholesterol, and triglyceride, that had been increased by CPF treatment. Our results demonstrated that JGJ ameliorates the effects of acute chlorpyrifos-induced toxicity. Therefore, JGJ has the potential to be used as a traditional medicine to alleviate insecticide toxicity.

This study was performed to investigate the possible effects of some plants protecting intact rat liver damaged by $CCl_4$. The extract of mugwort (Artemsiae capillaris), soybean sprout and pine leaf (Pinus strobus) inhibited markedly the in vitro activities of rat liver fatty acid synthase, whereas those of shiitake (Lentinus ododes), Houttuynia cortata, Acanthopanacis cortex and buckwheat leaves had less effects. Treatment with the water extract of pine leaf and soybean sprout caused a marked decrease in the $CCl_4$-induced toxicity in rat liver, judged from their effects on the levels of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase(GPT) in the serum. The extract of mugwort and soybean sprout reduced markedly the content of liver microsomal peroxides induced by $CCl_4$ treatment and serum TBA values, respectively. The extract of soybean sprout decreased efficiently the content of liver triglyceride elevated by $CCl_4$ treatment. Nevertheless, the extracts did not exert the supression of hepaticmegaly induced by $CCl_4$. The results suggest that soybean sprout and pine leaf may be potential sources improved the biochemical parameters like as peroxidation value or serum GOT and GPT, although these extracts had minimal effects in the increase of liver size induced by carbon tetrachloride.

These studies were attempted to investigate the therapeutic effect earthworm (Lamnodrilus gotai Hatai) extract (LS) on the liver damage induced by carbon tetrachloride ($CCl_4$) in rats. Male rats (Sprague-Dawley) were treated with sub-chronic concentration of $CCl_4$, which was 0.2 ml/kg of $CCl_4$ via peroral administration twice a week. LS administration to rats (6 ml/kg,po) prevented the development of fatty liver, necrosis and fibrosis induced by $CCl_4$. Furthermore, as compared with rats suspended after treated with $CCl_4$ only, LS treatment significantly decreased the increment in serum enzyme activities, liver enlargement and improved growth rate. This protective effect was observed when LS was given monthly for 4 months after $CCl_4$ treated for 2 months. These results suggest that earthworm extract has appreciable therapeutic effect on $CCl_4$-induced hepatotoxicity.

Objectives : Rheum undulatum Linne and Glycyrriza uralensis Fischer are widely used herbal medicine. In this study, anti-oxidant and liver protective effects of R. undunlatum extract (RUE) and G. uralensis extract (GUE) were investigated in HepG2 cells, respectively. Oxidative stress and liver fibrosis were induced by arachidonic acid (AA) and iron, and CCl₄.Methods : MTT assay was assessed for cell viability, and immunoblotting analysis was performed to detect expression of apoptosis related proteins. In addition, reactive oxygen species (ROS) and mitochondrial dysfunction were measured. In vivo, BALB/c mouse were orally administrated with the aqueous extract of 10 mg/kg RUE and 100 mg/kg GUE for 3 days and then, injected with CCl₄ 0.5 ml/kg body weight to induce acute liver damage. Serum ALT level was measured, and histological change was observed in Harris's hematoxylin and eosin stainResults : RUE and GUE pre-treatment increased relative cell viability in concentration dependent manner and altered the expression levels of apoptosis-related proteins such as procaspase 3, PARP and Bcl-xL. RUE and GUE also inhibited the mitochondrial dysfunction and excessive reactive oxygen species (ROS) production induced by AA and iron. In addition, RUE and GUE activated liver kinase B1 (LKB1), by increasing phosphorylation. Moreover, RUE and GUE treatment decreased liver injuries induced by CCl₄, as evidenced by decreases in histological liver damage as well as serum alanine amino transferase (ALT) level.Conclusions : These data suggest that RUE and GUE has anti-oxidant and liver protective effects against AA and iron-induced oxidative stress and CCl₄-induced liver injury.

The hepato-protective effects of the extract from Protaetia brevitarsis against hepatotoxicity by carbon tetrachloride ($CCI_4$) were studied in rats. The rats were orally treated with $CCI_4$ (50% in corn oil) at initial dose of $1\;m{\ell}/kg$ followed by $0.5m{\ell}/kg$ four times during 2-week period. The extract of P. brevitarsis (50, 100 or 200 mg/kg) or its vehicle was administered day after day from 1 week before $CCI_4$ Injection during five weeks. $CCI_4$ induced hepato-celluar degeneration and necrosis induced to increase in serum aspartate amintransferase (AST) and alanine aminotransferase (ALT) levels. In biochemical analyses, thiobarbituric acid-reactive substances (TBARS) and antioxidant enzymes such as superoxide dismutase (SOD) and catalase in hepatic tissues were remarkably increased by $CCI_4$ treatment. Not only increases in serum AST and ALT, but also induction of lipid peroxidation and antioxidant enzymes in hepatic tissues caused by $CCI_4$ were significantly attenuated by the P. brevitarsis extract in a dose-dependent manner. Such hepato-protective effects of P. brevitarsis extract were confirmed by histopathological examinations, wherein only mild hepatocytic vacuolations were observed in the liver of rats treated with a high dose (100 mg/kg) of P. brevitarsis extract in comparison with severe hepatocytic degenerations administered with $CCI_4$ alone. From these results, it is suggested that the extract of Protaetia brevitarsis could be a promising candidate for the protection of liver injury, based on the preventive effects against morphological cellular injuries, lipid peroxidation and serum biochemical parameters.

To investigate the antioxidative effects of an etbylacetate fraction extracted from the flowers of Chrysanthemum indicum L. (Chrysanthemi Flos) on the antioxidative system and lipid profiles of rats with ethanol induced hepatotoxicity. Sprague-Dawley rats weighing $100\~150$ g were divided into 5 groups: normal group (NOR), Chrysanthemi Flos EtOAC fraction (200 mg/kg) treated group (S1), $35\%$ etbanol (10 mL/kg) treated group (S2), Chrysanthemi Flos EtOAC fraction (200 mg/kg) and ethanol concomitantly treated group (S3) and Chrysanthemi Flos EtOAC fraction (400 mg/kg) and ethanol concomitantly treated group (S4), respectively. The antioxidative activity of each fraction was decreased in order of EtOAC, n-hexane, n-BuOH, water and chloroform. The growth rates and feed efficiency ratios were decreased by ethanol treatment, but were gradually restored to similar levels as in the NOR group by administering Chrysanthemi Flos EtOAC fraction. The whole blood concentrations of total cholesterol and LDL-cholesterol, and the activities of ALT and AST that were elevated by ethanol were significantly decreased in the Chrysanthemi Flos EtOAC fraction treated groups. It was also observed that the activities of SOD, catalase, xanthine oxidase and GSH-Px elevated by ethanol in rat liver were markedly decreased in the Chrysanthemi Flos EtOAC fraction treated group as compared to S2. These results suggest that Chrysanthemi Flos EtOAC fraction has possible protective effects against ethanol induced hepatotoxicity in rat liver.

BACKGROUND/OBJECTIVES: Ginger, a root vegetable, is known to have antioxidant and antiobesity effects. Preparation, such as by steaming, can affect the chemical composition of prepared root vegetables or herbs and can change their functional activities. In the present study, we investigated the protective effects of steamed ginger against oxidative stress and steatosis in C57BL/6J mice fed a high-fat diet. MATERIAL/METHODS: The levels of polyphenols and flavonoids in two different extracts of steamed ginger, i.e., water extract (SGW) and ethanolic extract (SGE); as well, their antioxidant activities were examined. Forty male C57BL/6J mice were fed a normal diet (ND, n = 10), high-fat diet (HFD, 60% fat, w/w, n = 10), HFD supplemented with 200 mg/kg of SGE or garcinia (GAR) by weight (SGED or GARD, respectively, n = 10) for 12 weeks. Serum chemistry was examined, and the expressions of genes involved in lipid metabolism were determined in the liver. Histological analysis was performed to identify lipid accumulations in epididymal fat pads and liver. RESULTS: The SGE had higher contents of polyphenols and flavonoids and higher DPPH and $ABTS^+$ free radical scavenging activities compared to those of SGW. Treatment with SGE or GAR significantly decreased the HFD-induced weight gain. Both SGE and GAR significantly reduced the high serum total cholesterol (TC), triglyceride (TG) and low-density lipoprotein levels induced by HFD. Compared to ND, HFD significantly increased hepatic TC and TG levels. SGE or GAR supplementation significantly decreased the increase of hepatic lipids by HFD. Interestingly, SGE had a more significant effect in reducing hepatic TC and TG levels than GAR. Furthermore, hepatic genes involved in lipogenesis and lipolysis were altered in both the SGED and GARD groups. CONCLUSIONS: The present study indicates that steamed ginger supplementation can decrease plasma TC and TG and can inhibit liver steatosis by regulating the expressions of hepatic genes.

The aim of this study was to evaluate the antioxidant activity and protective effect of extracts from the stems and leaves of Chrysanthemum boreale (CBSL) on t-BHP induced oxidative stress in human liver cells (Chang cells). Antioxidant activities in the extracts were determined for various radical scavenging activities including ferric reducing antioxidant power, 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, and oxygen radical absorbance capacity (ORAC). CBSL showed a very good scavenging effect of DPPH radical ($IC_{50}$ $0.009{\pm}0.002$ mg/mL), alkyl radical ($IC_{50}$ $0.004{\pm}0.001$ mg/mL), and hydroxyl radical ($IC_{50}$ $6.742{\pm}0.152$ mg/mL). CBSL also showed a strong antioxidant effect in the ORAC assay. In the MTT assay on human liver cells (Chang cells), the extracts showed protective effects by increasing cell viability, decreasing ROS, and restoring mitochondria membrane potential upon t-BHP induced oxidative stress. Our findings suggest that CBSL extracts are a potential therapeutic with protective antioxidant effects upon oxidative stress.

Objectives: The objective of this study is to investigate the effects of Silbi-um (SBU) extract on the alcoholic fatty liver induced by EtOH administration for 8 weeks. Methods: Male Sprague Dawley rats were used. All animals were randomly divided into 3 groups; Normal, EtOH and EtOH+SBU. The rats of EtOH group were daily treated with ethanol of 25% (v/v) for 8 weeks (n=10). EtOH+SBU group was orally treated with SBU water extract after ethanol administration (n=10). The rats of Normal group were treated with saline (n=10). After 8 weeks, the mean body weight, liver weight, and liver-body weight ratio were calculated. The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) of all groups were measured. The morphological alterations were observed using hematoxylin and eosin (H&E) and Oil Red O staining. Moreover, the alteration of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) levels were analyzed immunohistochemistrically. Results: The histological data showed that liver sections from EtOH group displayed severe steatosis. SBU extract significantly inhibited the progression of the alcoholic liver injury. The increased serum level of ALT and AST induced by ethanol administration were decreased by SBU extract. Furthermore, SBU extract significantly decreased the liver concentrations of $TNF-{\alpha}$. Conclusions: SBU water extract attenuated the alcohol induced fatty liver by improving hepatic lipid metabolism via suppression of $TNF-{\alpha}$ protein. SBU could be effective in protecting the liver from alcoholic fatty liver.
