  • To investigate the effects of Protaetia. brevitarsis extracts on the protection against liver damage by carbon tetrachloride($CCl_4$) in rat, two kinds of experiment were performed, firstly by the primary hepatocyte culture and secondly by the animal feeding. The primary hepatocyte culture with the extracts of P.brevitarsis showed significantly low activities of GPT, bile acid, and bilirubin, indicating an excellent protective effect against liver damage by $CCl_4$. Especially, below molecular weight 1,000 blew the water to have 32.1% recovery degree. In the seconde experiment, serum GPT activity was significantly decreased in water fraction of P. brevitarsis compared to $CCl_4$ treatment by 98.2%. Serum concentration of bile acid and bilirubin were tended to increased by $CCl_4$ treatment, but water fraction of P. brevitarsis and silymarin recovered the level. These consistent results in vitro and in vivo suggest that the extracts of P. brevitarsis may have strong protective effects against liver damage induced by the potential toxicants such as $CCl_4$.

  • This study was performed to investigate the ameliorating effect of a hangover beverage mixture (SBJ) that contains Dendropanax morbifera Lev. and several medicinal plant extracts, on hepatoprotection and alcohol-metabolizing enzymes in alcohol-induced hangover in both in vitro and in vivo models. In human hepatoma cell line, HepG2, 300 mM of ethanol-induced hepatotoxicity was significantly improved by pretreatment of SBJ by dose-dependent manner. In the in vivo study, administration of alcohol to rats raised to the concentration of blood alcohol and lactate dehydrogenase (LDH). Blood alcohol and LDH levels in SBJ-treated rats significantly decreased at 0.5 h and 8 h after acute ethanol administration (40%, 4.6 g/kg body weight) as compared to alcohol-treated rats. Hepatic alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activity were significantly higher in SBJ-treated rats than in alcohol-treated rats. SBJ supplementation reduced formation of malondialdehyde (MDA), and inhibited reductions of hepatic superoxide dismutase (SOD), hepatic glutathione (GSH), glutathione-S-transferase (GST), glutathione reductase (GR) and glutathione peroxidase (GPx) levels, compared with rats administered alcohol. Plasma catalase (CAT), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels showed unaltered resulted in all experimental groups compared with the control group. These results suggest that SBJ exhibit hepatoprotective properties by enhancing ADH, ALDH activity and stimulating the antioxidant defense system in alcohol-induced hangover.

  • Acer tegmentosum Max which is one of the specialized wildness medicinal herbs in gangwon province, has been widely used for hepatitis, liver cirrhosis, hepatic cancer, leukemia, diabetes mellitus, renal necrosis and edema, etc. In this study, the antioxidative and hepatoprotective effects of in vitro and in vivo were investigated in order to evaluate the possibility as hepatoprotective agents. Oral administration of methanol and butanol extact of Acer tegmentosum Max to d-galactosamine (D-GaIN) induced experimental liver injured rats was significantly reduced activities of marker enzymes(AST, ALT) and LDH activity in serum. Salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max potenty showed the scavenzing effect on DPPH and inhibitory effect on lipid peroxidation. And significantly decrcease of MDA level in liver and activities of SOD GSH-Px and catalase were significantly improved by the treatment of Sal. Results of this study revealed that Sal could afford a significant protection in the alleviation of D-GaIN-induced hepatocellular injury.

  • The purpose of this study is to inspect trends of the paper of Korean medical treatment on Carbon Tetrachloride-induced Hepatotoxicity and try to establish the future direction for development of Korean herbal medicine. We reviewed 79 papers which had been published from 1981 to 2010 in journals published in Korea. According to these studies, Carbon Tetrachloride-induced hepato-celluar degeneration and necrosis induced to increase in serum aspartate amintransferase (AST), alanine aminotransferase (ALT), Alkaline phosphatase (ALP), ${\gamma}$-Glutamyl transferase (${\gamma}$-GTP), lactate dehydrogenase (LDH), bilirubin, blood urea nitrogen (BUN) and albumin levels. In biochemical analyses, antioxidant enzymes such as superoxide dismutase (SOD), Glutathione S-transferase (GST) and catalase in hepatic tissue were remarkably incresed by Carbon Tetrachloride treatment. We found that some of the herbal extracts have a protective effect against Carbon Tetrachloride-induced Hepatotoxicity. More studies of oriental medicinal herbs are required for developing a treatment of hepatotoxicity.

  • Korean medical welfare facilities for the elderly provide the conveniences to care geriatric illness such as dementia and stroke. The medical welfare facility categorizes elderly care facilities, nursing homes, and geriatrics hospitals based on the Korean welfare of the aged act. The government makes an effort to secure feed rate and finances of medical welfare facilities. However, the qualitative improvement of facilities is inadequate. The purpose of this study is to analyze the conditions and problems of existing facilities using an environmental evaluation and to discuss the improvement direction related to the daycare centers for the elderly. The method of this study is literature review and field survey. Firstly, we analyzed the previous studies to develop the tool, evaluating the environment of day care centers for the old. Secondly, the items of environmental evaluation are deduced. Thirdly, we select the facilities to conduct field survey and analyze the results of field survey. Lastly, We discussed the problems and improvement directions through the results. It is judged that this study is an useful as the basic guideline to strengthen the minimum legal standards of day care center for the elderly due to the suggestion of insufficient environmental evaluation items.

  • Solvent fractions were prepared from traditional herbal drugs which of methanol extracts inhibited $CCl_4$-induced cytotoxicity in primary cultured rat hepatocytes and c ontinuously assayed their effects. Ethylacetate and n-buthanol fractions from Cibotii Rhizoma and chloroform fraction from Gelatina Nigra inhibited the release of LDH and GPT from $CCl_4$-treated hepatocytes, respectively. Water fraction (WAR) among solvent fractions from Astragali Radix showed the most potent inhibitory effect on the release of GOT or GPT by treatment with $CCl_4$. All of solvent fractions prepared from Eucommiae Cortex had no effect on $CCl_4$-induced cytotoxicity. Chloroform and ethylacetate fractions from Rehmanniae Radix Preparata increased the release of GPT from $CCl_4$-treated hepatocytes. n-Hexan, chloroform or ethylacetate fraction from 5 herbal drugs increased the release of LDH, GOT or GPT from normal hepatocytes at the dose of 1.Omg/ml. Administration of WAR suppressed the elevation of GOT, ALP activities and MDA contents in the serum as well as in the liver tissue of $CCl_4$-intoxicated rats. Based on these results, isolation of antihepatotoxic substances from WAR is under the process.

  • The mouse hepatitis virus (MHV-2) induces broad collapses, focal necrosis and cytolysis of hepatocytes, and leads to death after three to five days of intraperitoneal injection in mice. The present study investigated whether the combinatorial treatment of dimethyl dicarboxylate/amantadine (2:1) showed hepatoprotective and/or antiviral properties in MHV-2 infected ICR mice. In the study, we found that dimethyl dicarboxylate/amantadine group (VDDBA) increased the survival rate (30.8%) when compared to positive control, VL (7.7%) and that VDDBA lengthened the survival time (4.2 d)after MHV-2 infection. In addition, ALT and AST were well regulated when treated with VDDBA (p<0.01). Finally, we concluded that those results were probably from the inhibition of viral replication and at least antiproliferative effect on MHV-2.

  • Silymarin and curcumin have been used for supportive treatment of liver disease of difffrent etiology due to their hepatoprotective activities. The present study was carried out to investigate the hepatoprotective efffcts of silymarin and/or curcuma extract against hepatotoxins induced liver injury. To investigate hepatoprotective effects, the silymarin and/or curcuma extract were pre-treated orally to experimental animals. And thereafter a single dose of hepatotoxin, carbon tetrachloride ($CCl_4$) and acetaminophen were administered through oral or intraperitoneal route, respectively. Chronic liver damage was induced by subcutaneous injection of $CCl_4$ for 3 weeks (2 times/week). Hepatoprotective and therapeutic effects were monitored by estimating serurn ALT and AST levels and by measuring hepatic glutathione (GSH) and malondialdehyde (MDA)levels. Collagen type 1 was detected with irnrnunostaining to assess fibrosis. The results showed that the mix-ture of silymarin and curcuma extract significantly reduced serum biochemistry levels and MDA levels com-pared with those of control group in both acute and chronic animal models. In antifibrotic effect, the relative hepatic collagen content was significantly decreased by silymarin and/or curcuma extract treatment. It was concluded that the complex of silymarin and curcuma extract have a both hepatoprotective and therapeutic effect synergically in rat liver injury induced by heptotoxins.

  • The ethylacetate fraction of the overground portion of Polygonum aviculare L. exhibited the anti-lipid peroxidation and the liver protective effect in intoxicated rats. Through silica gel chromatography of the ethylacetate fraction monitered by bioassay, two flavonoids, avicularin and juglanin were isolated as active components. Avicularin and juglanin remarkablely inhibited the lipid peroxidation of rat liver induced by 50% ethanol. Especially avicularin exhibited the stronger anti-lipid peroxidation effect than juglanin. Avicularin as a main principle of Polygonum aviculare L. significantly exhibited liver protective activities by decreasing s-GOT and s-LDH levels which represent for the hepatotoxicity induced by $CCl_4$ in rats. In addition, avicularin significantly decreased not only s-LDH but also s-bilirubin levels in intoxicated rat induced by ${\alpha}-naphthylisothiocyanate\;(ANIT)$. These results suggest that avicularin has the protective effects against the hepatoxicity induced by $CCl_4$ and ANIT in rats.

  • This study was carried out to investigate the liver protective effects of extracts from Persicae Semen (WT-003, WT-005, WT-006). The acute hepatic injury was induced by intraperitoneal injection of alpha-naphtylisothiocyanate (75 mg/kg, p.o.) and treated with WT-006 (100 mg/kg/day, 200 mg/kg/day, 400 mg/kg/day). The experimental hepatic fibrosis was induced by bile duct ligation/scission(BDL/S), duration of 4 weeks and treated with WT-003, WT-005 or WT-006 (200 mg/kg/days for 4 week). In acute liver injury, WT-006 (200 or 400 mg/kg) lowered serum alanine transferase(ALT) and aspartate transferase(AST) significantly. In fibrotic rats, WT-006 treatment inhibited the hydroxyproline deposition in liver and lowered serum AST, ALT and ALP, significantly. These results suggest WT-006 extract, which does not contain amygdalin, from Persicae Semen have liver protective and antifibrotic effects in rats.
