Effects of water extract obtained from Chrysanthemum boreale M. (CE) on serum enzyme activities and Kupffer cells of carbon tetrachloride ($CCl_4$)-induced rats were investigated. Thirty-two healthy male Sprague-Dawley rats were divided into normal (N), $CCl_4$-induced (T), CE-supplemented (C), and $CCl_4$-induced and CE-supplemented (TC) groups. $CCl_4$ injection significantly increased aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and alkaline phosphatase activities in serum. Significant increases in total cholesterol and triglyceride concentrations were also observed in $CCl_4$-induced rats. Oral administration of CE at 300 mg/kg body weight significantly decreased serum enzyme levels and suppressed $CCl_4$ hepatotoxicity-induced lipid profile changes. Histological findings showed fatty change, fibrosis and increased number of Kupffer cells in T group. Electron microscopic examination showed increased lysosome content and dilation of rough endoplasmic reticulum within Kupffer cells in T group, whereas CE supplement attenuated liver injury in $CCl_4$-induced liver. These results indicated CE could significantly alleviate CC4-induced hepatotoxicity injury.

This experiment was conducted to study the effect of dietary vitamin E on the lipid composi-tion of rats treated with carbon tetrachloride. Rats were divided into five groups I. e. C(soybean oil with vitamin E(40mg/kg diet)) EF(CCl4 with vitamin E deficient diet) 40E(CCl4 with vitamin E(40mg/kg diet) 400E(CCl4 with vitamin E(400mg/kg diet) 800E(CCl4 with vitamin E(800mg/kg diet) Body weight gain and food efficient ratio were not observed significant differences. The liver weight was significantly increased in the CCl4 treated groups but the liver weight of 800E group was significantly lower than that of EF group. In EF and 40E groups kidney weights were significantly higher compared to that of C group. The content of total lipid in liver of 40E and 400E groups were significantly higher than that of control group but in 400E and 800E groups the contents were significantly lower compared with that of EF group. The content of triglyceride in liver was significantly higher in the CCl4 treated group and the content of cholesterol was significantly higher in the EF and 40E groups but those of 800E group were significantly lower compared with those of EF group. In CCl4 administration groups were significantly higher than those of control group and 400E and 800E groups were significantly lower than those of EF group.

Artemisia is a major edible vegetable in Korea and it has traditionally been used as a herbal medicine for the treatment of coughing, abdominal pain, indigestion, bleeding, jaundice, chronic liver disease and diabetes. However the biological and pharmacological actions of the herb have not been studied well. Recently it is known to possess antibacterial, antihelmintic and antifertility activities. But the effect of Artemisia capillaris extract on carbon tetrachloride($CCl_4$) induced liver damage in dogs have not been reported yet. This study was designed to investigate the effect .of Artemisia capillaris crude juice extract on $CCl_4$ induced liver damage in dogs. 30 clinically healthy dogs were divided into 2 groups: crude Artemisia capillaris juice treated group(CEC group) and carbon tetrachloride($CCl_4$) administerd group. The results are as follows: I. The degree of increase in AST activity and ALT activity in CEC group was lower than that in $CCl_4$ group and the recovery in CEC group was faster than that in $CCl_4$ group. 2. Changes of ALP concentration in CEC group were significant(P < 0.05) but changes of Total-bilirubin concentration were not significant(P < 0.05) in both groups. 3. The recovery of GGT concentration in CEC group was faster than that in $CCl_4$ group. 4. Hematological changes other than MCHC were significant(P < 0.05) in CEC group only and changes of GSH and Met-Hb concentration were significant(P < 0.05) in $CCl_4$ group.

In order to evaluate the protective effect of Kamicheungkantang(KCKT) on hepatic damage induced by $CCl_4$, the study was done. The blood chemistry and histological study were done following oral administration with materials. The results were obtained as follows. 1. KCKT extracts didn't show cytotoxicity against BALB/C mouse lung fibroblast cell. 2. In the hepatotoxicity with $CCl_4$, serum alanine aminotransferase(ALT) was significantly decreased in KCKT treated group as compared with control group. 3. In the hepatotoxicity with $CCl_4$, serum aspartate aminotransferase (AST) was significantly decreased in KCKT treated group as compared with control group. 4. In the hepatotoxicity with $CCl_4$, serum alkaline phosphatase(ALP) was significantly decreased in KCKT treated group as compared with control group. 5. In the hepatotoxicity with $CCl_4$, serum lactate dehydrogenase(LDH> was insignificantly decreased in KCKT but insignificantly as compared with control group. 6. In the hepatotoxicity with $CCl_4$, serum cholestorol was significantly decreased in KCKT treated group as compared with control group. 7. In the hepatotoxicity with $CCl_4$, serum triglyceride was insignificantly decreased in KCKT treated groups as compared with data of control. 8. In the hepatotoxicity with $CCl_4$, serum total bilirubin, direct bilirubin, ${\gamma}$-GTP were not changed in KCKT treated groups as compared with data of control. 9. In histopathological changes, fatty changes, vacuole, nucleotic changes and fibrosis were observed in control group and degree of changes was increased over time. Whereas no differences were observed in KCKT treated group These results suggested that KCKT extracts might be usefully applied for treatment of hapatic disease and also it was necessary to do more studies about its mechanisms.

Objectives : To compare the effects of low-frequency electro-acupuncture (EA) stimulation at left and right GB34s on hepatotoxicity in $CCl_4$-intoxicated rats. Methods : Rats were injected with $CCl_4$ and treated with 2 Hz electro-acupuncture (EA) at left and right GB34s for 15 minutes 3 times per week, for 10 weeks. Holder group, injected with $CCl_4$ and strained in a cylinder for same period as the EA group, was established to compare the hepatotoxicity against the two electroacupuncture groups. To estimate the effects of EA on hepatotoxicity in rats, body weight, liver weight and liver index were measured. Biochemical assays for serum ALT, AST, ALP and total cholesterol ; hematological analysis for RBC, WBC, PLT, hemoglobin, lymphocytes, neutrophils and monocytes ; and histology analysis of liver tissue were also performed. Results : Lymphocyte level in blood was significantly decreased by $CCl_4$-intoxication, and increased by low-frequency electroacupuncture applied on both left and right GB34s. Low-frequency EA applied on right and left GB34s significantly reduced serum ALT and AST, both of which had been increased by $CCl_4$-intoxication. Conclusion : Low-frequency electroacupunctures at both left and right GB34s have hepatoprotective effects on $CCl_4$-induced liver damage in rats. However, no significant differences were found between the effects of EAs at left and right GB34s.

커큐민(curcumin)은 강황 내 주요 폴리페놀 화합물의 한 성분으로 비만과 관련된 비알코올성 지방간염을 막아 주는 것으로 잘 알려져 있다. 이 연구의 목적은 고지방 식이로 키운 비만 마우스에서 사염화탄소($CCl_4$)로 유발한 간섬유증에 미치는 커큐민의 보호효과를 조사하기 위해 시도하였다. 군간 비교를 위해, 정상 식이와 고지방 식이로 키운 마우스에 7주간 $CCl_4$를 투여하면서 동시에 커큐민을 투여한 것과 투여하지 않은 군으로 나누었으며, 체중이나 혈당과 같은 대사 프로파일이나 지방세포의 크기 및 간섬유증의 변화를 조사하기 위해 혈청 생화학적 검사, 조직학적 검사 및 면역조직화학적 검사를 수행하였다. 또한 간세포 내자멸세포의 관찰을 위해 TUNEL 법을 사용하였다. 그 결과 고지방식이+$CCl_4$ 마우스에 커큐민을 투여한 군에서는 투여하지 않은 군에 비해 체중, 공복혈당 수치, 혈청 AST, ALT 수치가 낮았고, 지방조직 내의 지방세포 크기와 대식세포 및 비만세포 수가 감소하였다. 이와 반대로 정상식이+$CCl_4$ 마우스에 커큐민을 투여한 경우에는 투여하지 않은 군에 비해 체중과 비만세포 수 이외에는 통계학적인 차이가 없었다. 더욱이 커큐민은 간조직의 간실질세포의 자멸세포 수는 줄인 반면 활성 간성상세포 모양의 비실질세포의 자멸세포 수를 증가시켰다. 이 결과를 종합해 볼 때 커큐민은 비만 마우스의 간질환 진행에서 효과적인 항섬유 치료제로서 사용할 수 있을 것으로 사료된다.

This study was conducted to investigate the effect of fermented blackberry drinks (BD) on carbon tetrachloride ($CCl_4$)-induced liver injury in rats. Male Sprague-Dawley rats were randomly divided into four groups with 6 rats per group: control, $CCl_4$, $CCl_4$ plus BD $3ml\;kg^{-1}$, and $CCl_4$ plus BD $6ml\;kg^{-1}$. We found that the levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were significantly increased and the activity of antioxidant enzyme glutathione peroxidase (GPx) in the liver was decreased in rats treated with $CCl_4$ alone when compared with the control group. However, the administration of BD attenuated the levels of serum AST and ALT in $CCl_4$-treated rats. Moreover, the administration of BD significantly increased the activity of GPx in $CCl_4$-treated rat livers. Taken together, these results suggest that BD could protect the liver from $CCl_4$-induced hepatic damage.

Objectives : This study was designed to investigate effects of Sayeoksanhap-Pyeongweisan-Gambang (SPG) on gene expression in rats damaged by CCl4 Methods : We investigated the effects of SPG on gene expression in terms of microarray methods in rat liver which were obtained from rats damaged by CCl4. Results : Decreased gene expressions, which were induced by single injection of CCl4, were restored to those in normal rats by administration of SPG or herbal acupuncture. In acupuncture group, gene expressions were restored by 80% of those in control group. In oral administration group and combination group, gene expressions were restored above 90% of those in cuntrol group. Conclusion : These results suggest that oral administraion of SPG was useful to protect liver against CCl4 by its restoration of gene expressions in liver resected from rat damaged by CCl4.

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.
