To investigate an effect of the topical toluene application to .at skin on the liver injury, toluene (35 mg/$cm^2$) was sequentially applied for 3 or 5 days to rat skin and then the animals were sacrificed. 5 day toluene-treated rats showed the slight increase of live. weight per body weight(%) compared with control. Serum levels of xanthine oxidase and alanine aminotransferase activity were significantly increased both in 3 days and 5 days toluene-treated animals compared with control. In the histopathological findings, cytoplasmic degeneration of hepatocytes around the central vein was noted in the liver of rats applied with toluene to the skin. These results indicate toluene application to rat skin feds to somewhat slight liver injury. On the other hand, the hepatic benzylalcohol or aldehyde dehydrogenase activities were significantly decreased by toluene application to rat skin. In conclusion, the liver min was induced by toluene application to rat skin, and it can be hypothesized that accumulation of benzaldehyde in liver cell may be responsible for liver injury.

This research deals with an issue of preventive medicine in bioinformatics. We can diagnose liver conditions reasonably well to prevent Liver Cirrhosis by classifying liver disorder patients into fatty liver and high risk groups. The classification proceeds in two steps. Classification rules are first built by clustering five attributes (MCV, ALP, ALT, ASP, and GGT) of blood test dataset provided by the UCI Repository. The clusters can be formed by the K-mean method that analyzes multi dimensional attributes. We analyze the properties of each cluster divided into fatty liver, high risk and normal classes. The classification rules are generated by the analysis. In this paper, we suggest a method to diagnosis and predict liver condition to alcoholic patient according to risk levels using the classification rule from the new results of blood test. The K-mean classifier has been found to be more accurate for the result of blood test and provides the risk of fatty liver to normal liver conditions.

Objectives: Lately, non alcoholic fatty liver patients are increasing rapidly and the average age of patients are getting younger. Non alcoholic fatty liver often represents asymptomatic and korean pattern diagnosis is difficult to implement without symptoms. This study aimed to analyze interrelationship between non alcoholic fatty liver disease and Injinho-tang. Methods The AHP is a systematic procedure for analyzing the elements of any problem hierarchically. Based on survey of expertise, as series of pairwise comparison judgements is performed to evaluate the various elements in the hierarchy. We are expected to use the AHP analysis that would apply to oriental doctor's diagnostic process analysis. Results and conclusion Non-alcoholic fatty liver disease induced complex causes of the metabolic syndrome. Injinho-tang has been widely used disease that causes jaundice and liver biliary disease. According to AHP analysis, LFT is the most important facor in choosing Injinho-tang on non alcoholic fatty liver disease. BMI and body composition by bioelectrical impedance analysis are the next important factors. Personal hot temper also gives a big impact on choicing Injinho-tang on non alcoholic fatty liver disease.

Chronic liver diseases and hepatic cancer have been reported as 10% of cause of death in Koreans. Regardless of various causes, chronic liver disease accompanies commonly hepatic fibrosis. But still the mechanism of hepatic fibrosis remains poorly understood. Using the dimethylnitrosamine(DMN)-induced hepatic fibrosis rat model, We performed to evaluate the possible therapeutic effect of RIP(extracts of Phellodendron amurense and Patrinia scabiosaefolia) and to investigate the changes in referential connective tissue proteins($TGF-{\beta}_1$, ${\alpha}$-smooth muscle actin, and vimentin) as a marker of fibrogenesis. For these purposes, liver tissues were stained with H & E, and Azan staining for estimation of developing fibrosis. In the DMN-treated rat liver tissue, fibrosis were developed forming incomplete septal fibrosis. Whereas, in the RIP-treated rat liver tissues, the fibrosis were decreased recovering to normal morphology. The expressions of $TGF-{\beta}_1$, ${\alpha}$-smooth muscle actin($\alpha-SMA$), and vimetin were increased in the DMN-treated rat liver tissues, but decreased in the various areas of RIP-treated rat liver tissues. According to these results, RIP could be a possible therapeutic agent to reduce hepatic fibrosis, and the $TGF-{\beta}_1$, ${\alpha}$-SMA, and vimentin could be possible indicative markers of hepatic fibrosis development and recovery.

Objectives : This study investigated the hepatoprotective effects effects of Jageum-jung extract on alcohol-induced liver disease mice model. Methods : Alcoholic liver disease was induced by Ethanol in C57/BL6 male mice, which were fed Lieber-DeCarli liquid diet containing ethanol. Jageum-jung (100,200 and 300 mg/kg bw/day) were orally administered daily in the alcoholic fatty liver disease mice for 16 days. Results : The results indicate that Jageum-jung promotes hepatoprotective effects by significantly reducing aspartate transaminase (AST) and alanine transaminase (ALT) levels as indicators of liver damage in the serum. Furthermore, Jageum-jung decreased accumulation of triglyceride and total cholesterol, increased levels of superoxide dismutase (SOD) and glutathione (GSH) in the serum of the alcoholic fatty liver disease mice model. Additionally, it improved the serum alcohol dehydrogenase (ADH) activity. Conclusions : This study confirmed the anti-oxidative and hangover elimination effects of Jageum-jung extract, and suggests the possibility of using Jageum-jung to treat alcholic liver disease.

Chronical intake of alcohol can cause alcoholic fatty liver. Fatty liver is caused by fat infiltration: the state of high rate of fat in liver cells and by losing the balance between the synthesis and the secretion of fatty acid. It could be developed into liver necrosis and cirrhosis. Ka-Mi-Chung-Gan-Tang (KMCGT) is a decoction used for fatty liver as oriental medicines in China. The prescription is composed of Ginseng Radix, Bupleuri Radix, Scutellariae Radix, Pinelliae Tuber, Artemisiae capillaris Herba, Gardeniae Fructus, Zingiberis Rhizoma, Zizyphi Fructus and Glycyrrhizae Radix etc. We have induced alcoholic fatty liver by ethanol administration (6 g/kg, single dose/day, for a week) on rats and observed changes of triglyceride, cholesterol and lipid peroxidation in liver tissues of them. Also we checked the activities of GOT and GPT in blood of rats. KMCGT inhibited significantly the increase of triglyceride, cholesterol, lipid peroxidation level and effectively the increase of malondialdehyde (MDA).

Objective: The purpose of this study was to examine the protective efficacy of GHT on alcoholic liver injury. Methods: We measured the rate of alcohol oxidation, serum level of liver enzyme, lipid peroxidation level in liver tissue, and inflammatory related cytokine expressions in the liver. Results : GHT showed liver protective effects, lowered the levels of AST and LDH in serum and inhibited lipid peroxidation in liver tissue, and enhanced alcohol oxidation. GHT treatment up-regulated IL-10 in the liver, whereas it down­regulated $TNF-\alpha,\;TGF-\beta$, and Fas ligand. Conclusion : From these results, GHT is presumed to work in the liver in protective roles not through the pathway of alcohol metabolism but mainly by anti-inflammation activity in our model.

A 12-year-old spayed, female Siberian Husky dog weighing 40 kg was referred for sudden collapse without a traumatic history. A splenic mass and hemoperitoneum were identified by ultrasonography and abdominocentesis at a local animal hospital. Emergency exploratory laparotomy was performed once the patient was stabilized. A splenic mass and engorged hepatic mass in the torsed left liver lobe were identified. Partial hepatic lobectomy of the left lateral lobe was performed using a laparoscopic linear self-cutting stapler and the spleen was also removed using an ultrasonic scalpel. Histopathologic examination revealed a diagnosis of splenic hemangiosarcoma with metastasis to the liver. Chemotherapy was not performed because the client did not give consent. The patient was checked regularly until death on POD 324. The metastatic nodules had spread to the lungs and other liver lobes and had gradually increased in size. Liver lobe torsion is a rare condition in dogs, especially accompanying neoplasia. This case supports a potential relationship between liver lobe torsion and neoplastic liver mass in dogs.

Purpose: This study analyzes the impact of laparoscopic liver resection on intra-abdominal adhesion. Methods: Patients who underwent salvage liver transplantation after liver resection for hepatocellular carcinoma from January 2012 to October 2017 at our institution were included. Information about the severity of intra-abdominal adhesions was collected from a prospectively maintained database. Intra-abdominal adhesions were graded after the agreement of 2 surgeons who participated in the salvage liver transplantation based on predetermined criteria. Adhesion severity and demographic, operative, and postoperative data were compared between the laparoscopic group and the open group. Multivariate logistic regression was performed to consider potential factors related to severe adhesion during salvage transplantation. Results: Sixty-two patients who underwent salvage liver transplantation after liver resection were included in this study. Among them, 52 patients underwent open surgery, and 10 patients underwent laparoscopy. Adhesion was significantly more severe in the open group than in the laparoscopy group (P = 0.029). A multivariate logistic regression model including potential factors related to severe adhesion showed that laparoscopy (odds ratio, 0.168; 95% confidence interval, 0.029-0.970; P = 0.048) was the only significant factor. Conclusion: Laparoscopic liver resection for hepatocellular carcinoma can minimize intra-abdominal adhesion during salvage liver transplantation.
