To investigate effects of Angelica keiskei Koidz green juice on the liver damage of CCl4-treated tats, Sprague-Dawley male rats weighing 80~100g were divided into 4 groups of control group(CON), Angelica keiskei Koidz green juice-treated group(ANJ), CCl4-treated group(CCL) and Angelica keiskei Kodiz green juice and CCl4-treated group(ACL). Each group was sacrified after feeding for 4 weeks and examined the activities of transminase (sGOT, sGPT), superoxide dismutase (SOD), catalase and glutathione peroxidase(GSH-Px), and contents of lipid peroxide and glutathione in liver. The activities of sGOT and sGPT, and content of lipid peroxide after CCl4 treatment were markedly increased, compared to CON, but those levels were significantly decreased by the pretreatment of Angelica keiskei Koidz green juice as compared to CCL. The activities of SOD, catalase and GSH-Px were elevated by CCl4-treatment as compared to control group, and concomitant treatment of Angelical keiskei Koidz and CCl4 decreased those levels significantly except the activity of catalase. The hepatic content of glutathione was decreased by CCl4 and increased more abundant by Angelica keiskei Koidz administration than CCl4 treated group. These results suggest that Angelica keiskei Koidz green juice is believed to have a possible protective effect for the carbon tetrachloride-induced hepatotoxicity in rats.

To evaluate the cutaneous injury in liver damaged rats by toluene application to the skin, toluene(35mg/㎤) was sequentially applied for 5 days to the dorsal skin of liver damaged rats with $CCl_4$ (6 times ever other day:0.1$m\ell$/100 g body weight-50% $CCl_4$in olive oil). The cutaneous ultrastructural changes were unexoectably not observed in liver from $CCl_4$-treated rats although necrotic liver damage appeared under light microscope. In these animals by the application of toluene to rat skin the cutaneous xanthine oxidase activity was significantly increased(p<0.05), but cytochrome P450 content was not different from that of the control or only $CCl_4$-treated rats. On the other hand, the cutaneous superoxide dismutase and catalase activities in liver damaged animals were significantly respectively(p<0.05, p<0.001), decreased by toluene application to the skin compared with control and especially the former enzyme activity was significantty decreased(p<0.01), compared with that of liver damaged rate rat but glutathione peroxidase, glutathione-S-transferase activities were not significantly different from those of the control or liver damaged rats. Futhermore, the reduced gluathione content of skin was also significantly decreased by toluene application to the liver damaged animals. In conclusion, the great deposits of cerrous peroxide and ultramorphological changes in skin tissue of liver damaged animals by toluene application may be responsible for the oxygen free radical.

Hovenia dulcis Thunb (HDT) has been known folk medicine and has been used as therapeutic drug in the treatment of liver disease. Also it has been used as a detoxifying agents for alcoholic poisoning and promoting diuresis. However, there has not been any study on therapeutic effect of Hovenia dulcis extract on $CCl_4$ induced liver and kidney damage in rats. In this study, we report on therapeutic effects of Hovenia dulcis extract on $CCl_4$ induced liver and kidney damage in rats. Rats were divided into four groups of eighteen animals. Control group (DW) was administrated with distilled water 2.5 mL/kg per peritonial administration and then $CCl_4$ group (CCl) was administrated $CCl_4$ 2.5 mL/kg per peritonial administration, $CCl_4$+HDT extract group ($CCl_4$+HDT) was administrated HDT extrat (100 mg/kg) after $CCl_4$ 2.5 mL/kg administration, $CCl_4$+Silymarin group ($CCl_4$+Sily) was administrated Silymarin (50 mg/kg) after $CCl_4$ 2.5 mL/kg administration. The complete blood cell (CBC) count of RBC, WBC, PCV, Hb, MCH, MCV, MCHC and blood chemistry profile of AST, ALT, GGT, ALP, Total choloesterol, Tryglyceride, Total bilirubin, Amylase, Glucose, BUN, Creatinine, Lipase and pathologic changes were observed for 7 days after administration of D.W., $CCl_4$, $CCl_4$+HDT extract, $CCl_4$+Silymarin. The results are as follows : 1. RBC and PCV were significantly (p < 0.01) increased in all groups compared to D.W. but hemoglobin, MCH, MCV and MCHC were not showed significant difference during experimental periods. 2. AST, ALT, T-cholesterol, T-bilirubin, TG were significantly (p < 0.05) increased in all groups on day 3 compared to D.W. and were normal on day 7. 3. ALP was significantly (p < 0.05) decreased in $CCl_4$+HDT group on day 3 but Amylase was not showed significant difference during experimental periods. 4. BUN was significantly (p < 0.05) increased in $CCl_4$ group on day 7, but $CCl_4$+HDT group and $CCl_4$+Sily group were normal. Creatninie was significantly (p < 0.05) increased in $CCl_4$ group on day 3 and normal on day 7 but $CCl_4$+HDT group and $CCl_4$+Sily group were not showed significant difference during experimental periods.

Objective : In order to investigate the curative effect of Jucha-whan on the protective liver of guinea pigs induced by $CCl_4$ and d-galactosamine, serum transaminase(GOT, GPT), lactic dehydrogenase(LDH), alkaline phosphatase(ALP), glutathione S-transferase(GST), superoxide dismutase(SOD) were used to measure enzyme activities and lipid peroxide level. Method : The subject animals were divided into 5 groups; a control group(untreated), a subject group(administered with 0.9% Saline solution), a sample I (500mg/kg administered), sample II group (1000mg/kg administered), positive control group(administered with 200mg/kg silymarine). Result : The inhibitory effects on the serum GOT, LDH, ALP, SOD and Lipid peroxide level activities in protective liver of mice induced by $CCl_4$ were noted both in the sample I group and sample II. The inhibitory effects on the serum GPT activities in protective liver of guinea pigs induced by $CCl_4$ were noted in sample II group, but it was not noted in the sample I. The inhibitory effects on the GST activities in protective liver of guinea pigs induced by $CCl_4$ were not noted in both sample I and sample group II. The inhibitory effects on the serum GOT, GPT activities in protective liver of guinea pigs induced by d-galactosamine were noted in both sample I and sample II, but it was not recognizable statistically. The inhibitory effects on the serum LDH activities in protective liver of guinea pigs induced by d-galactosamine were noted in sample II, but it was not noted in sample I group. Conclusion : According to the above results, it is considered that Jucha-whan has treatment effects on liver injury in guinea pigs induced by $CCl_4$ and d-galactosamine. So it is required to study about the actions of mutual relation of medicines and patho-mechanism through experiment.

Objective : The aim of this study is to investigate the inhibitory effect of Injinchunggantang on hepatic sclerosis induced by $CCl_4$. Methods : Weight, liver function test and complete blood cell count, gross findings, and findings on liver tissue of the past(Hematoxylin & Eosin stain, Masson-Trichrome stain) were studied. Results : When it comes to the change of rats' body weight, The $CCl_{4^+}$Injinchunggantang group lost far less weight than The $CCl_{4^-}$only group. In the liver function test, which is focused on various areas such as total cholesterol, alkaline phosphotase, albumin, aspartate transaminase, alanine transaminase, The $CCl_{4^+}$Injinchunggantang group was much more closer to normal limit than the $CCl_4$ only group. In the complete blood cell count, including white blood cell, red blood cell, hemoglobin, hematocrite, platelet, The $CCl_{4^+}$Injinchunggantang group significantly closer to normal limit than $CCl_{4^-}$only group. In the gross findings of hepatic fibrosis models, Injinchunggantang showed inhibitory effect on hepatic fibrosis in the order. In the past findings of hepatic fibrosis models in Hematoxylin & Eosin, Masson-Trichrome staining, the liver in $CCl_{4^-}$only group showed atrophy and necrotic change with white nodules, whereas that of $CCl_{4^+}$Injinchunggantang group showed lesser significant change with the well_preserved tone of the tissue. In the extent of the inhibition of the hepatic fibrosis, the Injinchunggantang group showed statistically significant inhibitory effect(p<0.05) in the sclerosis model. Conclusions : These results show that Injinchunggantang have inhibitory effect on hepatic sclerosis induced by $CCl_4$ and further ultimately prevent liver cirrhosis. To obtain more credible results in this experiment, the invention of a new experimental model more similar to human hepatic sclerosis is still needed.

In order to test relationships between hepatotoxicity and transmethylation, activities of protein methylases and SAM (S-adenosyl-L-methionine)-synthetase were examined in liver tissues of rats treated with $CCl_4$. Also the concentrations of SAM and SAH were measured by HPLC in rat liver. The results are as follows. (1). Activities of protein methylases were not significantly changed in 24 hours after $CCl_4$ treatment. However, in 48 hours, activities of protein methylases were significantly increased in comparison with that of control. (2). Activity of SAM-synthetase was increased steadily in the time course after $CCl_4$ treatment. (3). S-adenosyl-L-methionine concentration of liver tissues in $CCl_4$-treated group was elevated in 24 hours, and then declined thereafter. But the SAH concentration was slightly decreased in the time course after $CCl_4$ treatment. These results indicate that SAM was very actively used in transmethylation reactions of $CCl_4$ damaged rat liver, suggesting the strong relationships between hepatotoxicity and transmethylation phenomena.

Korean red ginseng, the processed root of Panax ginseng Meyer, has been frequently used for various therapeutic purposes in oriental medicine. The present study investigated the possible effect of Korean red ginseng extract (RGE) for the treatment of liver fibrosis in mice injected with carbon tetrachloride ($CCl_4$) for 4 wk. Liver injuries were assessed by blood biochemistry and histopathology in mice treated with $CCl_4$ alone or $CCl_4$+ RGE (30, 100, and 300 mg/kg). Concomitant treatment with RGE and $CCl_4$ (three times/wk for 4 wk) effectively inhibited liver fibrosis as evidenced by decreases in plasma alanine and aspartate aminotransferases, as well as by the percentages of degenerative regions, numbers of degenerative hepatocytes, and collagen accumulation in hepatic parenchyma. Treatment with $CCl_4$ for 4 wk increased mRNA levels of transforming growth factor ${\beta}1$ and plasminogen activator inhibitor 1 in fibrogenic liver, whereas RGE (30, 100, and 300 mg/kg) significantly blocked the induction of fibrogenic genes by $CCl_4$. Similarly, RGE also prevented transforming growth factor ${\beta}1$-mediated induction of fibrogenic genes in human hepatic stellate cell lines. More importantly, RGE markedly reduced the number of ${\alpha}$-smooth muscle actin-positive cells in liver tissue. This study implies that RGE efficaciously protects against the liver fibrosis induced by chronic $CCl_4$ treatment, and may therefore have potential to treat liver disease.

The enzyme activities and antioxidative of tocopherol and ascorbate were investigated at the levels of liver, kidney homogenates and sera of SD-rats intoxicated with tetrachlorocarbon$CCl_4$. GOT and GPT activities of sera in the $CCl_4$ group were 3, 6 times increased compared to normal group. But they tended to decrease significantly in tocopherol and ascorbate administered group. As for BUN and total cholesterol they were the same. HDL-cholesterol in the $CCl_4$group was 42% decreased compared to normal group. HDL-cholesterol was about 26% increased in the tocopherol group and tocopherol ascorbate group compared to $CCl_4$ group. MDA and SOD activities in the liver and the kidney tissue homogenates were significantly increased in $CCl_4$ group compared to normal group. But they were decreased significantly in the tocopherol group and tocopherol-ascorbate group compared to $CCl_4$ group. In view of this study tocopherol and ascorbated were ascorbate were effective on the detoxication of liver and kidney injury.

These studies were carried out to investigate the effect of Herbal-acupuncture with Inzinsammultang extract on the recovery from liver injury of rats. The liver injury of rats induced with 0.3ml/ea carbon tetrachloride. The Herbal-acupunture with Inzinsam multang extract solution inserted into corresponding focus of Kansu(BL18) in rats. In this study, SD-Rats(Sprague-Dawley) were divided into 4 groups ; Normal group (None treated group), Control-group(The group not treated after $CCI_4$-intoxication), Treated group; Example I-group(Saline-injected groups after $CCl_4$-intoxication) and Example II-group(Inzinsammultang-injected groups after $CCl_4$-intoxication). Through histological observation, Example II-group sho-ws that liver injury is weaker than Control group.(p<0.05) Biochemical assays for each serum enzyme activities of AST, ALT and LDH, levels of albumin, ${\gamma}$-GT, TG, total cholesterol were performed. The results were summarized as follows 1. AST(Aspartate aminotransferase) activity in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication. Inzinsammultang-injected groups after $CCl_4$-intoxication showed significantly higher AST activities, compared with the Saline-injected groups after $CCl_4$-intoxication.(p<0.05) 2. ALT(Alanine aminotransferase) activity in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication. The Inzinsammultang-injected groups after $CCl_4$-intoxication showed significantly higher AST activities, compared with the Saline-injected groups after $CCl_4$-intoxication(p<0.05) 3. Level of Albumin in serum significantly increased in the Inzinsarnmultang-injected groups after $CCl_4$-intoxication. 4. LDH(Lactate dehydrogenase) activities in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication.(p<0.05) 5. ${\gamma}$-GT(Glutamyl transferase) in serum significantly decreased in the Inzinsammultang-injected groups after $CCl_4$-intoxication(p<0.05) 6. As for the TG(Triglyceride) levels in serum, Inzinsammultang-injected groups after $CCl_4$-intoxication is no significant differences compared with the Saline-injected groups after $CCl_4$-intoxication.(p<0.05) 7. Total cholesterol in serum significantly increased in the Inzinsarnmultang-injected groups after $CCl_4$-intoxication.(p<0.05) Those results indicate that the Inzinsammultang Herbal-acupuncture have significant effects on the liver injury induced by $CCl_4$. So it is expected that the Inzinsammultang Herbal-acupuncture can be used to cure inflammations and recover the functions of damaged liver cells.
