Background: Sarcopenia is associated with a poor prognosis in patients with liver cirrhosis. However, it is not known whether the rate of skeletal muscle depletion is also associated with a poor prognosis. We investigated the prognostic impact of the rate of skeletal muscle depletion in patients with liver cirrhosis. Methods: We included retrospectively all patients with liver cirrhosis who underwent both multiple computed tomography scans and hepatic venous pressure gradient (HVPG) measurements. Results: A total of 131 patients with liver cirrhosis were enrolled. The mean age of the patients was 53.7 years and alcoholic liver disease was the most common cause (61.8%). Sixty-four patients (48.9%) were diagnosed with sarcopenia. The median changes in skeletal muscle area per year (${\Delta}SMA/y$) were -0.89%. During a median follow-up period of 46.2 months (range, 3.4-87.6), 45 patients (34.4%) died. In multivariate analyses, age, Child-Pugh score, HVPG, presence of sarcopenia and ${\Delta}SMA/y$ were independently associated with mortality. Cumulative mortality was significantly higher in patients with ${\Delta}SMA/y$ < -2.4% than those with ${\Delta}SMA/y{\geq}-2.4%$ (log-rank test, P < 0.001). Conclusion: Both the presence and rate of change of sarcopenia are independently associated with long-term mortality in patients with liver cirrhosis.

Objectives : This study was performed to investigate the anti-fibrogenic effect of Curcumae Longae Radix on human hepatic stellate cells. Materials and Methods: Hepatic stellate cells (LX-2) were treated with various concentrations of Curcumae Longae Radix extract for 24, 48, and 72 hours. It was extracted with distilled water. After the treatment, cell viability, proliferation, cell cycle analysis, procollagen levels and the mRNA of the ASMA, TIMPl, TIMP2, MMP2, collagen type la, PDGF-receptor-beta and TGF-beta were measured by using MTT assay, BrdU assay, RT-PCR, and procollagen type 1 C-peptide EIA kit. Results : The viability of HSCs decreased in the 48 hours group, and proliferation of HSCs decreased as the concentration increased. In the cell cycle analysis, Curcumae Longae Radix decreased the ratio of M phase, and increased the ratio of apoptosis, G0/G1 and S phase. In the RT-PCR, the mRNA expression of the collagen type la and ASMA decreased with the Curcumae Longae Radix treatment. The production of procollagen by the HSCs was decreased by the treatment of Curcumae Longae Radix with high dose. Conclusion : These results suggest that Curcumae Longae Radix is helpful in the treatment of liver fibrosis as well as liver cirrhosis.

Liver cirrhosis is caused by virus, alcohol, toxins, drugs and chronic hepatitis. Clinical symptoms of liver cirrhosis are severe fatigue, nausea, fever, dyspepsia, anorexia, RUQ pain, jaundice, ascites. We applied oriental medicines to patient who had chronic hepatitis and liver cirrhosis. Sodalgeonbitang-gamibang has been used to treat hepatitis and liver cirrhosis because of its beneficial effects. The patient symptoms began to improve after about one month of treatment. After medication we could find remarkable effect on clinical symptoms and blood test. So we hope that this clinical study is helpful in treat a patient with hepatic disease.

The livers of 300 cases of Korean native cattle which were collected at slaughted house in Pusan were examined by gross and histopathological means to study patterns of pathological changes of the organ. 1. The most dominated lesion of the liver was those of fascioliasis showing incidence rate as 907 per cent of inspected cattle. 2. On age distribution of the fascioliasis lesion in the liver, higher incidence was seen in animals that were from 6 to 9 years of age. 3. Significant changes of the hepaticparenchyma caused by immature flukes included thrombosis, migrational tracks such as hemorrhagic foci with massive eosinophilia and hepatic necrosis. The changes of chronically infected livers of cattle were recognized as proliferation of periductal eosinophilic granuloma of various degrees in each portal triad. And this easential cholangiohepatitis might develop into multiple focal cirrhosis or diffuse perilobular cirrhosis. 4. Most cases with gross lesion of swelled bile ducts on visceral surface of the liver showed histological evidences of fascioliasis lesion throughout hepatic lobes.

During liver fibrosis, hepatic stellate cells (HSCs) undergo a complex activation process characterized by increased proliferation and extracellular matrix deposition, which is the major pathological feature of hepatic cirrhosis. Therefore, suppression of HSCs activation has been proposed as therapeutic strategies for hepatic fibrosis. We tried to screen the antifibrotic activity of natural products employing HSC-T6, hepatic stellate cell lines as an in vitro assay system. In the present study, we investigated the antiproliferative activity of aerial parts and roots of Pulsatilla koreana Nakai (Ranunculaceae). Our present study shows that roots of P. koreana exerted more strong inhibitory activity compared to its aerial parts. In addition, among the fractions of the aqueous methanolic extract of P. koreana roots, both n-hexane and $CHCl_3$ fraction showed the strong inhibitory activity on HSC proliferation. Further study also demonstrated that the n-hexane and $CHCl_3$ fraction of P. koreana roots significantly inhibited the HSC proliferation in time- and concentration-related manners.

Majority of hepatocellular carcinoma is evolved from a well differentiated cancerous condition such as hyperplastic lesions eg. adenomatous hyperplasia in cirrhotic liver or de no vo carcinogenesis and prolifenation along with dedifferentiation. Adenomatous hyperplasia is may be seen in severe acute hepatic injury, like submassive hepatic necrosis, or in chronic liver diseases, particularly liver cirrhosis and it has recently attracted much interest from both clinicians and pathologists because it is regarded as a precursor lesion of hepatocellular carcinoma. Hepatic adenomatous hyperplasia resembling focal nodular hyperplasia might have developed from localized vascular changes associated with chronic liver disease, pre-existing arterial malformation and early stage of angiogenesis in hepatocarcinogenesis. We present a patient who developed hepatocellular carcinoma after hepatic artery ligation.

Hepatic arterioportal fistulae are abnormal communications between the hepatic artery and portal vein. They are reported to be congenital or acquired secondary to trauma, iatrogenic procedures, hepatic cirrhosis, and hepatocellular carcinoma, but less likely to occur spontaneously. Extrahepatic portal venous obstruction (EHPVO) can lead to pre-hepatic portal hypertension. A spontaneous superimposed hepatic arterioportal fistula can lead to pre-sinusoidal portal hypertension, further exacerbating its physiology. This report describes a young woman with long-standing EHPVO presenting with repeated upper gastrointestinal variceal bleeding and symptomatic hypersplenism. Computed tomography scan demonstrated a cavernous transformation of the portal vein and a macroscopic hepatic arterioportal fistula between the left hepatic artery and portal vein collateral in the central liver. The hepatic arterioportal fistula was associated with a flow-related left hepatic artery aneurysm and a portal venous collateral aneurysm proximal and distal to the fistula, respectively. Endovascular coiling was performed for the hepatic arterioportal fistula, followed by proximal splenorenal shunt procedure. This case illustrates an uncommon association of a spontaneous hepatic arterioportal fistula with EHPVO and the utility of a combined endovascular and surgical approach for managing multifactorial non-cirrhotic portal hypertension in such patients.

Hepatocellular carcinoma (HCC) is a very common form of cancer worldwide and is often fatal. Although the histopathology of HCC is characterized by metabolic pathophysiology, fibrosis, and cirrhosis, the focus of treatment has been on eliminating HCC. Recently, three-dimensional (3D) multicellular hepatic spheroid (MCHS) models have provided a) new therapeutic strategies for progressive fibrotic liver diseases, such as antifibrotic and anti-inflammatory drugs, b) molecular targets, and c) treatments for metabolic dysregulation. MCHS models provide a potent anti-cancer tool because they can mimic a) tumor complexity and heterogeneity, b) the 3D context of tumor cells, and c) the gradients of physiological parameters that are characteristic of tumors in vivo. However, the information provided by an multicelluar tumor spheroid (MCTS) model must always be considered in the context of tumors in vivo. This mini-review summarizes what is known about tumor HCC heterogeneity and complexity and the advances provided by MCHS models for innovations in drug development to combat liver diseases.

Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease characterized by hepatic fat accumulation, while nonalcoholic steatohepatitis (NASH) is an advanced form of NAFLD characterized by hepatic inflammation, fibrosis, and liver injury, resulting in liver cirrhosis and hepatocellular carcinoma (HCC). Given the evidence that ginseng and its major bioactive components, ginsenosides, have potent anti-adipogenic, anti-inflammatory, anti-oxidative, and anti-fibrogenic effects, the pharmacological effect of ginseng and ginsenosides on NAFLD and NASH is noteworthy. Furthermore, numerous studies have successfully demonstrated the protective effect of ginseng on these diseases, as well as the underlying mechanisms in animal disease models and cells, such as hepatocytes and macrophages. This review discusses recent studies that explore the pharmacological roles of ginseng and ginsenosides in NAFLD and NASH and highlights their potential as agents to prevent and treat NAFLD, NASH, and liver diseases caused by hepatic steatosis and inflammation.
