Objectives : Our purpose of this study was to evaluate the association between abdominal adipose tissue and oriental obesity pattern identification. Methods : This study was performed in 78 healthy obese(BMI(body mass index)${\geq}25kg/m^2$) women in Seoul. Subjects underwent abdominal CT(computed tomography) scanning and were asked to complete the oriental obesity pattern identification questionnaire. Subjects were given written consent and this study was performed under permission of institutional review board of Kyung-hee East-west Neo medical center. Results : 1. VFA(visceral fat area) and VSR(visceral/subcutaneous adipose tissue ratio) were significantly correlated with stagnation of the liver qi(肝鬱, gan-yu)(p<0.05). But, other patterns were not significantly correlated with oriental obesity pattern identification(p>0.05). 2. We evaluated a difference of oriental obesity pattern identification score in visceral obesity group(n=34) versus non-visceral obesity group(n=44). Scores of all patterns except food accumulation(食積, shi-ji) were significantly higher in the visceral obesity group than in the non-visceral obesity group(p<0.05). Especially, there was a further significant difference in stagnation of the liver qi(肝鬱, gan-yu)(p<0.01). Conclusions : Generally, the stagnation of the liver qi(肝鬱, gan-yu) has a close relation with stress and depression. This study suggests that stress and depression might be correlated with visceral fat, and the use of oriental obesity pattern identification would be helpful for planning a treatment schedule of visceral obesity in the clinic.

Objective: This study was conducted to investigate the effect of Chaenomelis Fructus (CF) water extract on thioacetamide (TAA)-treated rats. Methods: Rats were divided into five groups: one normal group (n=8) and four with TAA-induced hepatic injury. These treatment groups were administered distilled water (n=8); silymarin 100 mg/kg (n=8); CF 100 mg/kg (n=8); and CF 200 mg/kg (n=8). In the TAA groups, the acute liver injury was induced via IP injection (200 mg/kg), and the silymarin and CF extract were then orally administered for three days. Subsequently, serum levels of GOT, GPT, and ammonia were confirmed as well as protein expressions using liver tissue. Results: In the liver injury-induced rats, CF administration reduced tissue damage and serum levels of GOT, GPT, and ammonia. In addition, CF increased the anti-oxidant proteins Nrf2, Keap1, HO-1, and catalase and significantly regulated matrix metalloproteinases (MMP-2 and MMP-9) and their tissue inhibitors (TIMP-1 and TIMP-2). Conclusions: In this animal model of liver injury induced by TAA, CF extract is determined to have a hepatoprotective effect by increasing anti-oxidant proteins that relieve damage and by regulating the expression of matrix metalloproteinases.

Non-alcoholic fatty liver disease (NAFLD), especially including non-alcoholic steatohepatitis (NASH) is one of the common diseases with 25% of prevalence globally, but there is no thera-peutic access available. Amomum villosum var. xanthioides (Wall. ex Baker) T.L.Wu & S.J.Chen (AX), which is a medicinal herb and traditionally used for treating digestive tract disorders in Asia countries. We aimed to examine pharmacological effects of ethyl acetate fraction of AX (AXEF) against ER stress-induced NASH mice model using C57/BL6J male mice by tunicamycin (TM, 2 mg/kg) injection focusing on the oxidative stress. Mice were orally administrated AXEF (12.5, 25, or 50 mg/kg), silymarin (50 mg/kg) or distilled water daily for 5 days, and outcomes for fatty liver, inflammation, and oxidative stress were measured in serum or liver tissue levels. AXEF drastically attenuated hepatic ER stress-induced NASH which were evidenced by decreases of li-pid droplet accumulations, serum liver enzymes, hepatic inflammations, and cell death signals in the hepatic tissue or serum levels. Interestingly, AXEF showed potent antioxidant effects by quenching of reactive oxidative stress and its final product of lipid peroxide in the hepatic tissue, specifically increase of metallothionein (MT). To confirm underlying actions of AXEF, we ob-served that AXEF increase MT1gene promoter activities in the physiological levels. Collectively, AXEF showed antioxidant properties on TM-induced ER stress of NASH by enhancement of MTs.

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.

To study effects of heated oil on lipid peroxidation in rat liver, rats were fed 3 and 6 weeks by intubating oils heated for l1(HA group) and 24 hours (HB group) at 18$0^{\circ}C$. The contents of lipid peroxides and vitamin E, and the activities of super oxide dismutase and glutathione peroxidase in liver were measured. Histological changes of the liver tissue were observed. In both HA and HE groups, the contents of lipid peroxides and the activities of superoxide dismutase were increased, but the activities of glutathione peroxidase and the contents of vitamin E in liver were decreased when compared to the control group which was fed fresh cora oils. During the oil feeding period, the activities of superoxide dismutase and the contents of vitamin E were not significantly changed, but the activities of glutathione peroxidase were decreased, and lipid peroxides were increased in the 3 weeks than in 6 weeks. In HB liver, the heterochromatin of nucleus increased, mitochondria swellen, cristae in mitochondria disappeared, fat droplet and secondary lysosome increased and lumen of rough endoplasmic reticulum enlarged, compared with that of the control group. These phenomena in HA group were less pronounced.

We examined LFT & Child-Pugh class to evaluate the effectiveness of oriental treatment. Result and Conclusion : We observed that herb-mod. acupuncture & moxibustion complex therapy decreased symptoms of liver cirrhosis and improved general condition of a patient who suffered from ascites and fatigue. In the LFT result, Child-Pugh class was improved.

Introduction: Liver fibrosis is defined unbalance of collagen metabolism, especially a stimulation of collagen synthesis and inhibition of collagen degradation, and antifibrotic effect is delaying or inhibition of new collagen synthesis and deposition in liver tissue. In this study, we investigated the antifibrotic and antioxidative effect of Solanum lycopersicum (SL) in liver fibrosis induced rats. Methods: : Rats were randomly divided in three groups (normal, CCl$_4$ and CCl$_4$-SL group) and were received 0.6 ml mixture of CCl$_4$ and olived oil (1:1 v/v) 3 times/week for 4 weeks except of the normal group.
