The present study aimed at assessing the protective effect of water extract from fruit body of the Grifola frondosa (GFW) on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity. Rats orally administered with GFW 0.5, 1.0, 2.0 g/kg for 14 days were treated with $CCl_4$ to induce hepatotoxicity. Pretreatment with GFW remarkably prevented the elevation of serum AST, ALT, ALP, LDH, $\gamma$-GTP, and liver lipid peroxides in $CCl_4$-treated rat and GFW administration in liver injured rats by $CCl_4$ showed significant (p<0.05) protection of liver as evidenced from normal serum enzymes and malondialdehyde (MDA) levels. In the ultrastructural changes, administration of $CCl_4$-induced damage of hepatocytes with vacuolation, a highly damaged endoplasmic reticulum, and degenerating nuclei. However, pre-administration with GFW preserved normal ultrastructure of hepatocytes. These results suggest that GFW had an effect to inhibit $CCl_4$-induced liver injury in rat, and that it could be used as an effective hepatoprotective agent against chemical-induced liver damage.

This study was carried out to investigate the effect of natural Eriobotrya japonica Lindl. vinegar on the liver protective effect of animals exposed to carbon tetrachloride. Eriobotrya japonica Lindl. vinegar (200 mg/kg) was administered at the same time for 28 days, and hepatotoxicity was induced by intraperitoneal injection of carbon tetrachloride on the $29^{th}$ day. The aspartate aminotransferase and alanine aminotransferase levels were significantly decreased (p < 0.001) and the superoxide dismutase and catalase activities were significantly increased (p < 0.001) in the Eriobotrya japonica Lindl. vinegar group compared to the control group. Histopathological observations showed that the Eriobotrya japonica Lindl. vinegar showed hepatic cell structure similar to normal group, and these results showed that it had an effect of suppressing and protecting the damage of liver cell. Therefore, Eriobotrya japonical Lindl. vinegar is considered to be a healthy functional food of the liver.

This study was designed to investigate the synergetic hepatoprotective effects from a mixture of Korean Red Ginseng and Pueraria Radix on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity in mice. Liver toxicity was induced by intraperitoneal administration of $CCl_4$ (0.6 mg/kg) in 12 groups of ICR mice. The negative control group was given $CCl_4$ without test samples and the normal group was given no treatment. Among treatment groups, the RGAP treatment (Korean Red ginseng acetic acid extract : Pueraria radix water extract, w/w, 38.4:57.6) decreased $CCl_4$-elevated ALT (101.60 IU/L), AST (833.89 IU/L), and LDH (365.02 IU/L) levels in the serum, and increased the SOD (11.03 unit/mg protein) and CAT (0.37 unit/mg protein) levels and the LPO levels ($59.09{\mu}M/g$ tissue) more than that in the mice group with $CCl_4$-induced control group hepatotoxicity. These results suggest that administration of a mixture of Korean Red ginseng and Pueraria radix decreases $CCl_4$-induced liver damage and enhances antioxidant activity in mice and imply that administration of the mixture in a certain ratio is more effective than single administration of either Korean Red ginseng or Pueraria radix alone.

Artemisia Iwayomogi Compositae) has been used clinically for jaundice, hepatitis, liver cirrhosis etc. The purposes of present study were to examine pharmacological effects of Artemisia Iwayomogi water extract(AIWE) on biochemical parameters (activities of ALP and LAP, contents of glucose, total bilirubin, total protein and albumin in serum, A/G ratio, and levels of hepatic glycogen) against hepatic injury by carbon tetrachloride($CCl_4$) in rats. The results were as follows ; 1. Increased ALP activities by $CCl_4$ were very significantly(p<0.001) decreased in AIWE posttreatment groups at 72 hours and significantly(p<0.05) decreased in AIWE pretreatment groups at 72 hours. Increased LAP activities by $CCl_4$ were significantly (p<0.05) decreased in AIWE posttreatment groups at 72 hours. A little increased total bilirubin contents by $CCl_4$ were very significantly (p<0.001) decreased in AIWE posttreatment groups at 24, 48 and 72 hours. 2. Increased glucose contents by $CCl_4$ were decreased in AIWE posttreatment groups. Decreased hepatic glycogen levels by $CCl_4$, were significantly (p<0.05) increased in AIWE posttreatment groups at 48 and 72 hours. 3. Decreased total protein contents by $CCl_4$ were significantly (p<0.05) increased in AIWE posttreatment groups at 48, 72 hours. Decreased albumin contents by $CCl_4$ were increased in proportion to numbers of AIWE treatments in AIWE pre- and posttreatement groups. Decreased A/G ratios by $CCl_4$ were significantly (p<0.05) increased in AIWE posttreatment groups at 48 hours. In conclusion, AIWE did not affect normal liver function and had hepatoprotective effects rather than direct preventive effects to $CCl_4$-induced cholestasis, damages in metabolisms of glucose, protein and bilirubin.

The purpose of present study was to examine pharmacological effect of Artemisia Iwayomogi methanol extract(AIME) on biochemical parameters(activities of AST, ALT, LDH, and ALP, contents of total bilirubin, total protein, albumin and A/G ratio in serum and levels of hepatic microsomal lipid peroxide and glucose-6-phosphatase activities) against hepatic injury by carbon tetrachloride($CCl_4$) in rats. Increased AST, ALT and LDH activities by $CCl_4$ were decreased in AIMS treatment group at 48 or 72 hours. Together, increased ALP activity by $CCl_4$ almost returned toward normal value in AIME treatment group at 72 hours. Serum total bilirubin contents increased to 87, 79 and 31% compared with normal group by $CCl_4$ which were decreased to 64, 42 and 26% in AIME treatment group at 24, 48 and 72 hours, respectively. Decreased contents of total protein and albumin, and A/G ratio by $CCl_4$ were recovered in AIME treatment group. Hepatic microsomal lipid peroxide levels(nmol malonic dialdehyde/100mg protein) increased to 140, 95 and 78% compared with normal group by $CCl_4$ which were decreased to 107, 74 and 65% in AIME treatment group at 24, 48 and 72 hours, separately. Hepatic microsomal glucose-6-phosphatase activities decreased to 60, 50 and 53% compared with normal group by $CCl_4$ at 24, 48 and 72 hours, respectively, which were increased at 72 hours in AIME treatment group. In conclusion, AIME enhanced the amelioration process from $CCl_4$-induced lipid peroxidation, degeneration of liver cell, and impairment of protein and bilirubin metabolisms.

The kiwi (Actinidia deliciosa) is well known to contain anti-oxidants. In this study, we investigated the anti-oxidant effects of kiwi extract on carbon tetrachloride ($CCl_4$) induced liver injury in BALB/c mice. The radical scavenging effect of 80% methanol extract of Halla-Gold kiwi was observed. For the animal study, mice were randomly divided into four groups: normal group, $CCl_4$-induced model group, kiwi extract administered group, and silymarin treated group. The kiwi extract was provided daily for 10 days. At the 24 h after last administration, $CCl_4$ was injected. The kiwi extract showed strong inhibitory effect of DPPH radicals and superoxide scavenging. In animal study, administration of $CCl_4$ resulted in significantly elevated plasma levels of ALT and AST but they decreased in kiwi-extract pretreated group. Anti-oxidant enzymes such as GSH-px and GSH-rd were restored in the kiwi extract treatment group. Histopathological degeneration was also prevented in the kiwi extract treated group compared with of the control group, which exhibited $CCl_4$-induced hepatotoxicity. On the basis of the obtained results, it can be concluded that kiwi extract showed protective effects, not only as anti-oxidant effects, but also in the protection of hepatotoxicity in $CCl_4$-intoxicated mice.

Hepatoprotective effects of the extract of Kochiae fructus (KF), a traditional oriental medicinal plant, were evaluated against carbon tetrachloride($CCl_4$)-induced liver damage in rats. Male Sprague-Dawley rats were divided into control, $CCl_4,\;CCl_4$ plus methanol extract of KF (KFM-$CCl_4$), and $CCl_4$ plus butanol extract of KF (KFB-$CCl_4$) groups. KFM and KFB were orally administered once a day (200 mg/kg body weight) for 14 days. A mixture of 0.2 mL/100 g body weight of $CCl_4$ in olive oil was injected at 30 minutes after the final administration of KFM and KFB. The KFB pretreatment resulted in a significant decrease in the serum transaminase and lactic dehydrogenase levels in the $CCl_4$-treated rats. The $CCl_4$ treatment significantly lowered the activities of glutathione, glutathione reductase (GR), glutathione-S-transferase (GST), superoxide dismutase (SOD), catalase and glutathione peroxidase (GSH-Px). However, pretreatment with KFM and KFB resulted in a significant increase in the glutathione, GR and GST levels. KFB increased the activities of SOD, catalase and GSH-Px, but KFM did not alter them. Pretreatment with KFM and KFB resulted in a significant decrease in the production of aminopyrine N-demethylase in the $CCl_4$-treated rats. KF extract would appear to contribute to alleviate the adveISe effect of $CCl_4$ treatment by enhancing the hepatic antioxidant defense system.

This study was done to investigate the protective effects of ethanol extract Artemisiae vulgaris L(Av) on carbon tetrachloride(CCl₄)intoxicated rats. Male sprague Dawley rats(200~210g)was used. experimental groups were divided into normal group, CCl₄-control group, and ethanol extract CCl₄-treated group. CCl₄-treated groups were injected with CCl₄ 0.6mg/kg.b.w(i.p). The activities of Alanine aminotransferase(ALT), Aspartate aminotransferase(AST), Alkaline phosphatase(ALP), Glutamyl transpeptidase(γ-GT), Lactate dehydrogenase(LDH) in extract pretrated group was significantly decreased(p<0.05) compared to the CCl₄-control group. The contents of triglyceride, cholesterol and lipid peroxide were significantly decreased(p<0.05). whereas the contents of HDL-cholesterol and glutathione(GSH) were significantly increased(p<0.05). These results suggest that extract of Artemisiae vulgaris L(Av) has hepatoprotective effect in the CCl₄-intoxicated rats.

The brown alga Saccharina japonica is consumed as a foodstuff in many countries. Carbon tetrachloride ($CCl_4$) is a potent hepatotoxin that is used to assess hepatotoxicity in animal models. This study assessed the protective effect of S. japonica extract (SJE) on $CCl_4$-induced acute liver injury in rats. Experimental rats were divided into the following three groups: control, $CCl_4$, and $CCl_4$+SJE; the latter two groups were given 150 or 300 mg SJE/kg orally for 10 days. Three hours after the final treatment, all rats-except for those in the control group-were administered intraperitoneal injections of $CCl_4$. One day later, blood and liver samples were collected for evaluation biomarker of levels. Aspartate transaminase (APT; GPT) and alanine aminotransferase (ALT; GOT) levels were markedly lower in the $CCl_4$+SJE group than the $CCl_4$ group. The hepatic superoxide dismutase (SOD) activity of the $CCl_4$+SJE group was significantly lower than that of the $CCl_4$ group. In comparison, glutathione S-transferase (GSH) and catalase (CAT) levels were significantly higher in the $CCl_4$+SJE group. Western blotting revealed that SJE attenuated the $CCl_4$-induced EGFR and MAPK activity in the liver. Thus, we conclude that SJE protects against $CCl_4$-induced hepatotoxicity.

This study was carried out to find whether phenidone (1-phenyl-3-pyrazolidinone), a cyclooxygenase as well as a lipoxygenase inhibitor, exhibits the preventive effect on carbon tetrachloride $(CCl_{4})-induced$ acute liver injury in rats. Rats were pretreated with phenidone at a dose of 50 or 200 mg/kg (p.o.) once daily for 3 consecutive days before $CCl_{4}$ administration. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured. Malondialdehyde (MDA) production was determined as an index of lipid peroxidation in the liver and serum. The histopathological changes in the liver were also examined in each group. The reduction in body weights was significantly inhibited in the phenidone-treated group than in the $CCl_{4}$ control group. Significant increase in the relative liver weights of the phenidone-treated groups was observed compared with either the vehicle or $CCl_{4}$ groups. Elevation of serum AST and ALT activities occurred after $CCl_{4}$ treatment was significantly attenuated by the pretreatment with phenidone. The elevation of MDA levels in liver and serum were completely inhibited in phenidone-treated groups. The protective effects on phenidone-treated groups were confirmed histopathologically. These results suggest that phenidone may be a useful protector through modulation of hepatic inflammation in $(CCl_{4})-induced$ acute liver injury.
