  • The leaves and roots of Ligularia stenocephala, which are widely used as a food in Korea, were investigated for their antioxidant activities and cytotoxicity in vitro, and their hepatoprotective effect, alcohol detoxicant efficacy, and memory-enhancing property were investigated in vivo. The unique odor of the leaves was analyzed by GC-MS. Lipid peroxidation, superoxide anion formation, and DPPH radicals were inhibited remarkably by the extracts of the leaves and roots. The leaves of this edible plant significantly protected the hepatotoxicity induced by carbon tetrachloride and further diminished the blood alcohol content in mice. While the roots of this plant exhibited adequate cytotoxicity against four human tumor cell lines, especially against melanoma, the leaves revealed relatively weak activity. Both the leaves and the roots exerted an excellent ameliorating property on scopolamine-induced memory impairment in the passive avoidance task using an animal model. The hexane fraction of the leaves was analyzed by GC-MS, suggesting that a series of terpenoids may be odorous compounds in this plant.

  • 홍경천의 간보호 효과를 알아보고자 사염화탄소를 투여하여 간손상을 유발시킨 흰쥐에 홍경천 물추출물을 투여한 후 간독성 보호효과를 알아본 결과, 혈청중 ALT, AST, LDH, ALP 활성도는 사염화탄소 투여에 의해 증가하였으나, 사염화탄소 투여 후 홍경천 물추출물의 투여로 유의적인 감소를 나타내었다. Total cholesterol, total lipid, triglyceride는 사염화탄소 투여에 의해 증가하였으나, 사염화탄소 투여 후 홍경천 물추출물의 투여로 유의적인 감소를 나타내었다. 한편 phospholipid는 사염화탄소만 투여한 CCL군과 사염화탄소 투여 후 홍경천 물추출물을 투여 한 군 모두 유의성 차이는 없었으나 홍경천 물추출물을 투여함으로 증가함을 알 수 있었다. HDL-cholesterol의 함량은 사염화탄소만 투여한 CCL군에 비해 사염화탄소 투여 후 홍경천 물추출물을 투여 한 RSLIII군에서 유의적으로 높은 수치를 보였다. LDL-cholesterol은 사염화탄소만 투여 한 군과 사염화탄소를 투여후 홍경천 물추출물을 투여한 군간 유의적 차이를 확인할 수 없었다 이상의 결과에서 사염화탄소 투여로 각종 효소 활성도 및 지질의 함량이 증가되었는데 이는 사염화탄소 투여로 간세포에 손상이 유발되었음을 알 수 있었고, 사염화탄소 투여 후 홍경천 물추출물을 투여한 군에서 사염화탄소 투여로 증가된 각종 효소 활성도 및 각종 지질의 함량을 저하시키므로서 홍경천 물추출물이 손상된 간기능을 회복시킬 수 있을 것으로 사료된다.

  • Objectives : The aim of this study is to investigate the preventive effect of Puerariae Flos ethanol extract (PE) on methionin and choline deficient (MCD)-diet-induced Nonalcoholic fatty liver disease (NAFLD) in C57BL/6J mice. Methods : In the in vivo experiments, C57BL/6J mice were divided into 4 groups; Normal group, Control group, MCD+PE 100 group, and MCD+PE 300 group. After 4 weeks, body weight, liver weight, biochemical parameters for liver function test, histological changes, reverse transcription polymerase chain reaction (RT-PCR), and Western blot were assessed. Results : Mice lost body weight with the MCD-diet and the MCD+PE 100 group and MCD+PE 300 groups lost less than the control group, though showed no statistical significance. Liver weights were decreased by the MCD diet, but MCD+PE 300 groups were increased significantly. In the liver function test, all the values were decreased with the MCD-diet, MCD+PE 100 group and MCD+PE 300 groups were increased significance. In histological findings of the livers, MCD-diet induced severe fatty accumulation in the livers, but this fatty change was reduced in the MCD+PE 100 group and MCD+PE 300 groups was inhibited respectively. In lipid accumulation factors (such as SREBP-1c, $C/EBP{\alpha}$, PPAR-${\gamma}$), MCD+PE 100 group and MCD+PE 300 groups showed inhibitory effect on liver lipogenesis by reducing associated gene expressions caused by MCD diet. Conclusions : We were able to know that Puerariae Flos ethanol extract (PE) shown hepatoprotective effects via a decrease on the hepatic lipogenesis factors in the experimental NAFLD Models.

  • 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.

  • Hepatoprotective effects of an aqueous extract prepared from the aerial part of Agrimonia eupatoria L., a species of agrimmony, were investigated in experimental liver-damaged models. To investigate hepatoprotective effects, the agrimmony extract were fed orally to experimental animals. Thereafter a single dose of hepatotoxin, carbon tetrachloride $(CCl_4)$ or D-galac-tosamine was orally administrated. Chronic liver damage was induced by oral administration of $CCl_4$ for 2 weeks (1 time/day). Hepatoprotective effects were monitored by estimating serum AST and ALT levels. The results showed that the agrimmony extract significantly reduced AST and ALT levels compared with those of control group in both acute and chronic animal models. It was concluded that the agrimmony extract have hepatoprotective effects against rat liver injury induced by $CCl_4$ or D-galactosamine.

  • The present study was undertaken in order to investigate betaine production by tissue culture and its medicinal effect in Lycium chinone Mill. In order to ulvestigate the protective effect of L. chinense on the hepatoxicity induced by $CCl_4$, 0.5 g/kg water extract of the compound mixture (leaves, roots and shoots) of L. chinense and its callus were fed to rat (SD line) once a day. As a result, the activity of GOT and GPT in the group fed compound mixture (GOT 760.4 and GPT 540 Karmen unit) and callus (G0T 772.1 and GPT 556.4 Karmen unit) was decreased in the blood serume relative to the controlled rat group (GOT 949 and GPT 640 Karmen unit) and the same result was obtained in the group fed with 0.1 g/kg sylimarin (the activity of GOT and GPT was shown 492.6 and 320.4 Karmen unit respectively. These results strongly indicate that water extracts of the mixture and callus from L. chinense do have the same decreasing effect of GOT and GPT in the hepatotoxic rat induced by $CCl_4$.

  • ${\beta}$-cyclodextrin has an ability to protect compounds from oxidative reaction by collecting them within its ring-like structure. So, In harsh condition ($40^{\circ}C$), marker compound, quercetin, was dramatically reduced in Hovenia dulcis fruit extract containing dextrin at 4 and 8 week compared to 0 week, but not that containing ${\beta}$-cyclodextrin. To evaluate the effects of dextrin and ${\beta}$-cyclodextrin on protective effect of H.dulcis fruit extract against alcohol-induced liver damage, The mice were orally injected alcohol, H. dulcis fruit extract/dextrin (HD) and H. dulcis fruit extract/${\beta}$-cyclodextrin (HCD), respectively, for 7 days. The mice orally administrated with alcohol significantly enhanced the serum concentration of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and the activity of lactate dehydrogenase (LDH) in serum compared to the control group. HD and HCD significantly decreased the levels of serum ALT and AST and serum LDH activities compared to alcohol group. And also alcohol group significantly increased the level of total cholesterol compared to the control group, but HD and HCD significantly reduced it compared to the alcohol group. However, the levels of TG in blood were not significantly changed in all groups. The activities of alcohol dehydrogenase (ADH) were significantly increased in HD and HCD group although those of aldehyde dehydrogenase showed an increasing tendency. This data suggested that HD and HCD were able to induce alcohol degradation in the liver tissues. All together, the results showed that HCD demonstrated their ability to protect liver from alcohol-induced damage on equal terms with HD.

  • This study was performed using animals to confirm the effect of tourmaline-ionized water (TIW) the properties of which were changed by tourmaline energy and electric discharge. In the ICR mice fed high-fat diet, body weight increasing rate of the TIW-treated group (Exp) was generally decreased and moreover exhibited significance at 11th week (P<0.05) compared with the control (Con) group fed distilled water, although water intake of the Exp group was lower than that of the Con group. In the ICR mice with $CCl_4$-induced hepatotoxicity, AST and ALT activities of the Exp group were not significant but showed some decreasing trend, and histological damage of liver was less compared with thatof the Con group. On the study of ethanol-induced hangovers in Sprague-Dawley rat, blood alcohol concentration was significantly decreased (P<0.01), activity of GST, antioxidant enzyme related to the alcohol metabolism, was increased in liver tissue (P<0.05), and AST and ALT show a tendency to be decreasedin the Exp group. These results suggest that drinking TIWhas not only some obesity preventing effect but also an alcohol detoxification effect and liver protecting effect in vivo. It is supposed due to a structural change of water cluster and a property which maintains the changed structure through tourmaline energy and electric discharge. Therefore, TIW has a potentiality to be developed as functional water with several beneficial effects as well as for daily drinking, but further study on the mechanism related with efficacy will be necessary.
