  • Objectives : This study aimed to evaluate the protective effect of Orostachydis Herba (OH) and Fermented OH (OHF) against the acute liver injury by lipopolysaccharide (LPS). Methods : OHF by 4 lactic bacteria such as (Lactobacillus hilgardii (OHF1), Leuconostoc mesenteroides (OHF2), Pediococcus acidilactici (OHF3), Saccharomyces cerevisiae (OHF4)) were prepared. Samples were selected to OHF0, OHF2, OHF3 based on UPLC analysis, DPPH, ABTS radical scavenging activities. To evaluate the protective effect of OHF on liver injury mice, ICR mice were divided into 5 groups: Normal mice (Nor), LPS (20 mg/kg) treated mice (Veh), administrated OHF0, OHF2 OHF3 200 mg/kg body weight during 8 days before LPS injection. Serum and liver were collected 24 hours after LPS injection. Results : The activity was high in order of OHF0 and OHF3 in DPPH and ABTS radical scavenging activities. The quercetin contents for bioactive ingredient of OH was 5.39, kaempferol contents was 9.94 by UPLC analysis. The LPS-treated vehicle group significantly increased liver weight, and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in serum. In contrast, administrated OHF3 group decreased liver weight, AST, ALT. In addition, OHF3 groups reduced the elevated levels of reactive oxygen species (ROS) in serum and tissues. Moreover, AP-1, iNOS and COX-2 were significantly decreased in OHF2 and OHF3. But $NF-{\kappa}B$ p65 and $TNF-{\alpha}$ only showed a significant reduction in OHF3. Conclusions : Therefore, these results suggest that fermented Orostachydis Herba might be protective effect on liver injury through anti-oxidant effect.

  • We investigated if Chlorella vulgaris (CV) has protective effects on cadmium (Cd) induced liver damage in male Sprague-Dawley (SD) rats. Forty rats, aged 5 weeks old and weighed 90-110g, were divided into a control (with Cd free water), 50 ppm of $CdCl_2$ in drinking water treated groups (Chlorella 0% diet group (Cd/CV0%), Chlorella 5% diet group (Cd/CV5%) or Chlorella 10% diet group (Cd/CV10%). All the rats had freely access to water and diet for 8 weeks. The results show that body weight gain and relative liver weight had significantly lower in Cd/CV0%-treated group than in Cd/CV-treated groups. Hepatic Cd contents showed significantly less by feeding CV (P<0.05). Cd/CV0%-treated rats had significantly (P<0.05) higher hepatic T-MTs, and Cd-MTs concentrations, compared to Cd/CV5% or Cd/CV10% treated rats. The MT I/II mRNA was expressed in the liver of all experimental rats. Its expression was more increased in Cd/CV5%- or Cd/CV10%-treated rats, compared to control and Cd-treated rats. Thus, this study suggested that CV would have a protective effect on Cd-treated liver injury by the reduction of Cd concentrations and stimulation of Cd-MT binds in the liver. However, more studies are needed to identify the proper mechanism of CV and liver toxicity.

  • Objectives : This study was undertaken to determine if a combined(SPe) has a protective effect against functional failure induced by $CCl_4$ in rat liver. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to rats and data were obtained. Liver injury was estimated by measuring aspartate aminotransferase(AST) and alanine aminotransferase(ALT) activity in serum. Lipid peroxidation was examined by measuring malondialdehyde, a product of lipid peroxidation. GSH activities in liver tissues were also measured. Results : When rats were treated intraperitoneally with $CCl_4$, serum AST and ALT were increased compared with the control, which was significantly inhibited by pretreatment of SPe. SPe also prevented reduction in GSH induced by $CCl_4$. Conclusion : Above results suggest that SPe exerts protective effect against $CCl_4$ by its antioxidant action in liver tissues. Thus, SPe may be used in prevention and treatment of drug-induced liver cell injury. However, the precise mechanisms of SPe protection remain to be determined.

  • Objectives : This study was carried out to research the protective effects of Sagunja-Tang(SA) through in vivo experiments, and tried to investigate the relation between oxidation of liver tissues and deficiency of Qi. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to mice and metabolic data were obtained. In order to measure the degree of liver injury, serum level of alanine aminotransferase(AST), aspartate aminotransferase(ALT), creatinine, blood urea nitrogen(BUN), total protein(TP) and glucose were measured. Lipid peroxidation of liver slice was examined by measuring malondialdehyde(MDA), a product of lipid peroxidation. Results : SA had protective effects on $CCl_4$ induced acute liver injury by decreasing serum level of ALT. Kidney injury was induced by injection of $CCl_4$ too, and SA protected kidney injury by decreasing serum level of creatinine and BUN. Conclusions : Through this study, we found that SA have healing effects on liver and kidney injury of $CCl_4$ induced oxidative stress that is similar to deficiency of Qi. And further studies have to be followed to certify the mechanisms.

  • This research was performed to investigate the protective effect of Chungpesagan-tang (CPS) against ischemic damage in PC12 cells. To elucidate the mechanism of the protective effect of CPS on ischemic insult, cell viability and changes in activities of Superoxide dismutase, Glutathione Peroxidase, Catalase, Caspase 3 and the production of Malondialdehyde were observed after treating PC12 cells with CPS which was metabolized by rat liver homogenate. Pretreatment of CPS with liver homogenate increased its protective effect against ischemic insult by reducing the harmful effect of CPS itself. (omitted)

  • A chronical intake of Substantial amount of alcohol would disrupt anormal function of liver if not develop liver diseases in relatively short period. In order to out whether ginseng or ginseng plus high protein diet have any protective effects on the liver of chronical alcoholist from developing malfunction enzymatic activities of both glutamic-pyruvic and glutamic-oxaloacetic transaminases were measured on serum of rats maintained with basal low protein diet, basal diet plus 1 percent ginseng and high protein (40%) plus 1 percent ginseng and administered intraperitoneally with a Constant amount of ethanol either periodically or chronically. It was found that, unlike human subject GOT content was exceedingly high and significant difference was found either among treatment or among sexes thus indicating that either ginseng intake or high protein diet plus ginseng has a protective effect on the liver function of ethanol treated rats. From these results, it was suggested that the dietary ginseng might, have a protective effect on the alcohol hepatic disturbance. As one of probable mechanisms for the characteristic pharmacological activity, it was considered that a secondary action of the saponin of the dietary ginseng would result in the anti-inflammatory through the stimulation of de nove synthesis of certain functional proteins in hepatic organs.

  • This study was designed to evaluate the protective effect of silkworm hemolymph against ${\gamma}-irradiation$ induced damage in the liver of mice. Female Balb/C mice (6 weeks old) were exposed to ${\gamma}-irradiation$ (6 Gy) and administered orally to silkworm hemolymph ($5ml\;kg^{-1}$ BW) for 7 days post-irradiation. The body weight, spleen index, plasma aspartate transaminase (AST), plasma alanine transaminase (ALT), and liver malondialdehyde (MDA) levels were determined. Compared with irradiated control mice, the activity of plasma AST and the level of MDA were significantly decreased in mice treated silkworm hemolymph. These results show that silkworm hemolymph is found to have a protective effect against ${\gamma}-irradiation$ induced damage in mice.

  • Objectives : This experiment was conducted to verify the effects of some oriental herbs(Alny Cortex et Ramulus, Artemisiae Capillaris Herba, Aurantii Nobilis Pericarpium, Giseng Radix, Hoveniae Semen, Puerariae Flos, Puerariae Radix, and Xanthii Fructus) which have been used in the treatment of alcoholic diseases, on alcoholic metabolism, and on alcoholic liver damage. Methods : The effects of the herbs on the activities of alcohol dehydrogenase(ADH), aldehyde dehydrogenase(ALDH) were evaluated and their protective effects of liver function and cells from alcoholic damage were analysed. For the evaluation of the protective effects, the levels of glucose, triglyceride, BUN, AST, and ALT in serum of rats were measured. Results and Conclusions : It is concluded that Puerariae Radix interferes with the ADH activity directly, thereby reducing the toxicity of alcohol, resulting in enhancing alcohol-tolerance and protecting liver functions. Also Artemisiae Capillaris Herba interferes both ADH and ALDH activities. Isolation of the biologically active compounds from Puerariae Radix and its detailed characterization are matters for future research.
