  • Artemisia princeps PAMPANINI has been used in traditional medicine of the treatment of inflammatory, liver dysfunction and order disorder in the far east countries including Korea. The present study was carried out to investigate the hepatoprotective effects of ethanol extract of Artemisia princeps (AP) and its fermented agents (AP-F) by lactic acid bacteria derived from human intestinal bacteria on liver injured rat induced by $CCl_4$ and d-galactosamine. Hepatoprotective activity was monitored by estimating serum ALT, AST, ALP, LDH, superoxide dismutase (SOD), glutathione redeuctase (GR) and glutathione peroxidase (Gpx) activities in the liver injured by hepatotoxin. Pretreating rats with AP or AP-F at the same dosage regimen significantly suppressed the acute elevation of serum transaminase, ALP, LDH and GR activities, and significantly increased the lowering of blood SOD and GR activites induced by hepatoxin. Based on these findings, it is presumed that AP and APF may have the hepatoprotective effect on $CCl_4$ and d-galactosamine-induced hepatotoxicity rat.

  • The efficacy of alcoholic extract of Kasni (Cichorium intybus L.) to control hepatic damage induced by aflatoxin $B_1$ was explored in Swiss albino mice. Aflatoxin $B_1$ was administered orally to the mice with a daily dose of $66.6{\mu}g/kg$ body weight till three months. A signifi-cant increased in thio barbituric acid reactive substances (TBARS) levels with concomitant reduction in enzymatic (glutathione-s-transferase, glutathione peroxidase, superoxide dismutase, and catalase) and nonenzymatic (reduced glutathione) antioxidants were shown in aflatoxin treated group of mice. However, there was a significant reduction in increased TBARS levels and elevation in enzymatic. and non enzymatic antioxidant levels in group of mice which received alcoholic extract of kasni (300 mg/kg bw / day) along with aflatoxin. Histopathological analysis of liver samples also confirmed the hepatoprotective effect of kasni extract. These results suggest that kasni shows hepatoprotective effect against aflatoxin $B_1$ induced hepatic damage in mice.

  • The ethanolic extract of Bacopa monnieri Linn. aerial parts were studied far its hepatoprotective effect on $CCl_4-induced$ hepatotoxic rats. The extract was found to decrease significantly $CCl_4-induced$ elevation of SGOT, SGPT, ALP, bilirubin and total cholesterol. But, it increased HDL-cholesterol level and liver weight with respect to $CCl_4$ toxic rats. The extract was also found to decrease significantly the $CCl_4-induced$ elevation of lipid peroxidation and increase the activity of antioxidant enzymes (SOD and CAT) and GSH level in the liver of extract treated rats when compared with $CCl_4$ induced rats. Histopatholosical profiles showed that the extract had significant protective effect against $CCl_4-induced$ liver injury, which corroborates the above findings. Hence it may be possible that the mechanism of hepatoprotection of the extract is due to its antioxidant effect.

  • GRF (Korean Red Ginseng mixed formula) consists of six herbs such as Ginseng Radix rubra Koreana, Lycii Fructus, Artemisiae Capillaris Herba, Poria, and Glycyrrhizae Radix and Hoveniae Fructus. For the evaluation of hepatoprotective effect of GRF, the study was performed on protective effect against hepatic damage induced by galactosamine in vitro and ccl4 in vivo and also elucidate antioxidant activity. In vitro assay with 1.1 mM galactosamine, protection (%) was 44% (GR), and 58% (GRF-A) at 50 ug/ml. GRF effectively protected fatty degenertion and necrosis in murine hepatic damage induced by ccl4. For the -antioxidant study, GRF inhibited hemolysis of erythrocyte and decolored DPPH (2,2-diphenyl-l-picrylhydrazyl) free radical in a dose dependent manner more effetively than GR alone in vitro. GRF and GR significantly suppressed the time course $(1\;hr{\sim}6\;hr)-level$ of MDA (malondialdehyde) following AAPH (2,2'-azo-bis-(2-amidino -propane) dihydrochloride) treatment in vivo as compared with control data. From the results it can be concluded GR and GRF exerted the hepatoprotective effect by dint of antioxidant activity.

  • To evaluate hepatoprotective effects of G009, an hepatoprotective agent which was extracted from the mycelia of Ganoderma lucidum IY009, we were, studied using $CCl_4$-and galactosamine-induced hepatotoxicity in rats. The ratio of liver weight to body weight, the value of glutamic oxaloacetic transaminase(GOT) and glutamic pyruvic transaminase (GPT) activities, the change of a lipids in serum, and the inhibitory activity of malondialdehyde (MDA) formation in serum and liver homogenate were determined in rats. G009 was not significantly changed of the ratio of liver weight to body weight and the content of lipids in serum, but reduced the serum GOT and GPT values in $CCl_4$-and galactosamine-induced hepatotoxicity in rat. Especially, protective effect of G009 on rat hepatic injuries induced by galactosamine was significantly appeared. $CCl_4$ increased markedly the formation of lipid peroxides in the liver homogenate, and serum. The increase of lipid peroxides by $CCl_4$-induced hepatotoxicity was markedly reduced by the treatment with G009. These results suggest that the hepatoprotective effects of G009 may be correlated with its anti-lipid peroxidative activity, therefore, it may be potential agent for hepatic disease.

  • Background: Acute hepatic failure is a life-threatening critical condition associated with rapid deterioration of liver function and liver transplantation. Several studies have shown that Panax ginseng Mayer has antidiabetic and hepatoprotective effects. However, the hepatoprotective effect of ginseng berry is still unveiled. In this study, we evaluated the hepatoprotective effects of ultrasonication-processed ginseng berry extract (UGBE) on acute hepatic failure model in rats. Methods: Ginseng berry extract (GBE) was ultrasonically processed. The GBE, silymarin, and UGBE were orally administered to male Sprague-Dawley rats for 4 wk. Twenty-four h after the last administration, rats were challenged with D-galactosamine (D-GalN)/lipopolysaccharide (LPS). Results: After ultrasonication, the component ratio of ginsenosides Rg2, Rg3, Rh1, Rh4, Rk1, Rk3, and F4 in GBE had been elevated. Administration of UGBE significantly increased the survival rate of D-GalN/LPS-challenged rats. Pretreatment with UGBE significantly decreased serum alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels in D-GalN/LPS-challenged rats in a dose-dependent manner. The levels of enzymatic markers for oxidative stress (superoxide dismutase, glutathione peroxidase, catalase, and glutathione) were increased by UGBE treatment in a dose-dependent manner. Tumor necrosis factor alphalevel, inducible nitric oxide synthase activities, and nitric oxide productions were reduced by UGBE treatment. In addition, hemeoxygenase-1 levels in liver were also significantly increased in the UGBE-treated group. The protein expression of toll-like receptor 4 was decreased by UGBE administration. Hematoxylin and eosin staining results also supported the results of this study showing normal appearance of liver histopathology in the UGBE-treated group. Conclusion: UGBE showed a great hepatoprotective effect on D-GalN/LPS-challenged rats via the toll-like receptor 4 signaling pathway.

  • Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang(SGT) has been developed as prescriptions for the Soyeumin constitution. The hepatoprotective effect of the water extract of Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang(SGT) was investigated against carbon tetrachloride (CCl4)-induced hepatic damage. A single intra-peritoneal injection of CCl4 produced liver damage in rats as manifested by the significant rise of aspartate aminotransferase(AST), alanine aminotransferase(ALT), and alkaline phosphatase(ALP) in serum as compared to those of untreated normal group. Pretreatments of rats with Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang(SGT) 500 mg/kg for 7 days) were significantly reduced AST, ALT, and ALP levels compared with CCl4-treated control group. Treatment of rats with CCl4 led to significantly increase in lipid peroxidation and significantly decrease in cytochrome P450 and P450 reductase. The oral administration of Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang(SGT) water extract significantly inhibited the accumulation of microsomal thiobarbituric acid reactive substance (TBARS) and increased the cytochrome P450 and P450 reductase activity. All these biochemical alterations resulting from CCl4 administration were inhibited by the pretreatment with Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang(SG1) extract. These results suggest that Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang(SGT) water extract can be useful as a hepatoprotective agent. And the effect of NO modulation by NO synthesis or precursors, and Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang (SGT) water extract was researched on chronic liver damage induced by CCl4 administration. It was observed that endogenous NO protected the liver from lipid peroxidation, fibrosis, and damage. Osuyubujaijung-tang(OBT) and Sipyimiguanjung-tang(SGT) water extract showed the hepatoprotective effect on the chronic liver cirrhosis model and relationship with NO modulation.

  • The aim of the present investigation was to examine whether YH439, a hepatoprotective agent, exerts protective effect against hepatotoxicity and reduces the production of cytokines and NO in lipopolysaccharide (LPS)-primed rats with carbon tetrachloride ($CCl_4$). Administration of LPS following a single dose of CCl4 injection resulted in remarkable elevations of the serum $TNF{\alpha},{\;}IL-l{\beta$ and IL-6 level. The serum NO level was moderately elevated and severe liver damage was evidenced by increases in serum alanine aminotransferase (ALT) and sorbitol dehydrogenase (SDH) activities. YH439 decreased the levels of TNF, $IL-l{\beta}$, IL-6, ALT, SDH as well as NO in the serum elevated by CCl4+LPS in a dose-dependent manner. Inducible nitric oxide synthase (iNOS) level was decreased in the liver of rats treated with YH439. The increased iNOS activity induced by LPS and $interferon-{\gamma}$ was significantly decreased in RAW 264.7 cells by YH439 treatment. YH439 increased the GSH level decreased by $CCl_4+LPS$ and suppressed the ratio of GSSG/GSH. The reduction of hepatotoxicity by YH439 may associated with the decrease in the production of cytokines as well as suppression of iNOS protein in conjunction with an increase in the GSH level.

  • The particle size of medicinal materials is an Important physical property that affects the phar-maceutical behaviors such as dissolution, chemical stability, and bioavailability of solid dosage forms. The size reduction of raw medicinal powder is needed to formulate insoluble drugs or slightly soluble medicines and to improve the pharmaceutical properties such as the solubility, the pharmaceutical mixing, and the dispersion. The objective of the present study is to evaluate physiological activity of amorphous and nano-particle prep-arations of insoluble drug, ursodeoxycholic acid (UDCA), which were made by three types of fine grinding mills. The change of physical properties of ground UDCA was conformed by Mastersiger microplus and X-ray diffraction. We have investigated hepatoprotective effects of the nano-particle preparations of UDCA by plan-etary mill, vibration rod mill and jet mill in $CCI_4$-induced oxidatively injured mouse liver. The results showed that nano-particle preparations of UDCA all decreased reactive oxygen sepecies generation and lipid peroxi-dation in $CCI_4$-induced oxidative stress mice. Among them, nano-particle preparations by vibration rod mill and jet mill showed more significantly hepatoprotective effects compared to intact UDCA and planetary mill-ground UDCA. These results suggest that ground UDCA with vibration rod mill and jet mill shows a high amorphous state and the improved dissolution.
