Recently, herbal drugs haver been used world wide. and generally regarded as safe with no serious adverse reaction. Drug-induced liver injury (DILI) is one of frequent cause of liver diseases. If DILI is not treated, it can be developed into liver cirrhosis, hepatoma, etc. Currently, DILI has been reported to be common cause of acute hepatitis, and oriental medicine and folk remedy are not exception. We encountered one case of DILI, cause by folk remedy. Patients complained chest discomfort, yellow skin and urine, nausea, vomiting. Lab test showed elevated level of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transpeptidase (r-GTP), total bilirubin (TB). We estimated acute DILI and stopped taking folk medication made by himself. After 1 week of treatment, the clinical symptoms and liver function improved. Genetic and environmental factors as well as drug itself decide the hepatic toxicity, and the major DILI are belonged in acute type. So we need to get more attention to folk medication to help preventing the DILI cause by folk remedy.

Background: Although there more than 1,000 liver transplantations (LTs) are performed in Korea annually, their immense cost remains a great hurdle. Hence, in an attempt to reduce the medical costs of LT, a program was initiated at a public hospital affiliated with the Seoul National University Hospital. Methods: A total of 11 LTs have been successfully executed since the first LT performed at Seoul Metropolitan Government Seoul National University Boramae Medical Center in July 2011 through December 2014. Results: Nine patients (81.8%) were male and two (18.2%) were female. The mean age of patients was 53.4±11.4 years. Hepatitis B virus-related liver disease (n=6, 54.5%) was the most common causative disease, followed by alcoholic liver disease (ALD) (n=4, 36.4%). The actuarial 3-year survival rate was 90.9%. The median total medical cost of LTs was US $41,583 (calculated from operation to discharge), but only $11,860 was actually charged for patients with health insurance coverage. One female patient who had undergone deceased donor LT for alcoholic liver cirrhosis died during follow-up. This patient was non-compliant with the medical instructions after discharge, and finally expired due to septic shock at 10 months post-LT. Conclusions: In the public hospital, LT was successfully performed at a much lower cost. However, LT guidelines and peritransplant management protocols for patients with ALD must be established before escalating LT at public hospitals since ALD with poor compliance is one of the most common causes of complications at public hospitals.

Background: Circadian rhythm disturbance caused by shift work has adverse effects on the metabolic homeostasis of the liver. Disruption of the metabolic homeostasis of the liver causes fat accumulation in the liver. The aim of this study was to investigate the correlation between shift work and non-alcoholic fatty liver disease (NAFLD) among male workers in the steel manufacturing industry of Korea. Methods: Based on medical examination data collected in June 2020, 2,511 male subjects from one steel manufacturing company in Korea were selected in total. NAFLD was evaluated using abdominal ultrasound, which was performed by two experienced radiologists. The multinomial logistic regression analysis was performed by adjusting for age, physical activity, smoking history, alcohol consumption, body mass index, waist circumference, blood pressure, blood glucose, lipidemia, liver function test, employment duration, and hepatotoxic materials exposure status. Results: Compared to daytime workers, the odds ratio (OR) of moderate-severe NAFLD in shift workers was 1.449 (95% confidence interval [CI], 1.028-2.043). Compared to daytime workers, the ORs of moderate-severe NAFLD were significantly higher for the group that engaged in total shift work for more than 20 years (OR, 2.285; 95% CI, 1.051-4.970), the group that was not allowed to sleep during night shift work (OR, 1.463; 95% CI, 1.030-2.078), and the group that consumed food during night shift work (OR, 1.580; 95% CI, 1.093-2.284). Conclusions: There was a correlation between shift work and moderate-severe NAFLD in male steel manufacturing workers. There will be a need for more research related to the correlation of shift work with steatohepatitis and cirrhosis in the future.

Hepatitis C virus (HCV) is one of the important human pathogen that can cause acute and chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. Recently, the third generation radiation immuno assay (RIA) method has been developed as a very sensitive test to detect anti-HCV antibody. However, false positive is the problem with RIA test. To solve this the RIA results were compared to those of 5-antigen recombinant immunoblot assay (5-RIBA) and reverse transcription-polymerase chain reaction (RT-PCR). Among 12,767 serum samples tested from clinic visitors, total 275 (2.2%) samples were antibody positive by RIA. RIBA was performed with 148 RIA positives cases but among them was shown eighty five was antibody positive and sixty three (42.6%) was negative result. However, nested RT-PCR test was shown also carried out with 43 positive, 6 intermediates and 25 negatives of RIBA. As a result of the nested RT-PCR results, HCV antigen were detected in RIBA positive, 33.3% (2/6) RIBA intermediate and 12% (3/25). Clinical syndrome of all 148 patients as a with chronic active hepatitis (46.0%), cirrhosis (18.9%), hepatocellular carcinoma (8.1%) and others (27.0%) and they were positive in reaction by RIA test. But RIBA positive patients with 34.9% of chronic active hepatitis, 18.6% of cirrhosis, 4.6% of hepatocellular carcinoma and 41.9% of others were detected to be positive case by nested RT-PCR.

Chronic viral infection has been reported to cause a range of hepatic lesion, including hepatic fibrosis, cirrhosis and hepatocellular carcinoma (HCC) in a wide variety of animal species. Woodchucks (Marmota monax) chronically infected with woodchuck hepatitis virus (WHV) develop similar progressive hepatic inflammatory and neoplastic lesions that are remarkably similar to those associated with HBV infection in humans. Twenty two-month-old offspring from woodchucks (Marmota monax) experimentally infected with woodchuck hepatitis virus, were purchased. One randomly chosen animal was autopsied. The liver exhibits marked cirrhotic changes characteristic of the pre-transformation phase of WHV. We believe that this may represent a new suitable and cost-effective model for the disease processes associated with hepadnaviruses in a number of other species, most notably Hepatitis B virus infection in man.

Acer tegmentosum Max which is one of the specialized wildness medicinal herbs in gangwon province, has been widely used for hepatitis, liver cirrhosis, hepatic cancer, leukemia, diabetes mellitus, renal necrosis and edema, etc. In this study, the antioxidative and hepatoprotective effects of in vitro and in vivo were investigated in order to evaluate the possibility as hepatoprotective agents. Oral administration of methanol and butanol extact of Acer tegmentosum Max to d-galactosamine (D-GaIN) induced experimental liver injured rats was significantly reduced activities of marker enzymes(AST, ALT) and LDH activity in serum. Salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max potenty showed the scavenzing effect on DPPH and inhibitory effect on lipid peroxidation. And significantly decrcease of MDA level in liver and activities of SOD GSH-Px and catalase were significantly improved by the treatment of Sal. Results of this study revealed that Sal could afford a significant protection in the alleviation of D-GaIN-induced hepatocellular injury.

Hepatocellular carcinoma (HCC) is the most frequent type of malignant liver tumor and a high impact health problem worldwide. The prevalence of HCC is particularly high in many Asian and African countries. Some HCC patients have no symptoms prior to diagnosis and many of them therefore present at late stage and have a grave prognosis. The well-established causes of HCC are chronic hepatitis B virus (HBV) or chronic hepatitis C virus (HCV) infection or alcoholic cirrhosis and nonalcoholic steatohepatitis. The Barcelona Clinic Liver Cancer (BCLC) Staging System remains the most widely used for HCC management guidelines. To date, the treatments for HCC are still very challenging for physicians due to limited resources in many parts of the world, but many options of management have been proposed, including hepatic resection, liver transplantation, ablative therapy, chemoembolization, sorafnib and best supportive care. This review article describes the current evidence-based management of HCC with focus on early to advance stages that impact on patient overall survival.

A small number of pathologic entities such as Budd-Chiari Syndrome, cirrhosis, focal nodular hyperplasia, and superior and inferior vena cava obstruction has been reported to result in focal areas of increased uptake of radiocolloid on the hepatoscintigram. We recently studied a patient with focal accumulation of $^{99m}Tc-phytate$ at the inferior aspect of the liver, at the junction of the right and left lobe. The superior vena cava scintiangiogram was taken for the evaluation of the superior vena cava obstruction and collateral circulations. As a result of superior vena caval obstruction a considerable amount of blood flowed to the liver through the anterior parietal and periumblical venous channels. A certain fraction of radiocolloid delivered by the rete mirabile perfused to a localized area of the liver. This would explain the hot spot around the porta hepatis in this case.

Furfural, an organic solvent, is widely used as synthetic component material in producing chemical products. However, furfural has been reported that it shows strong toxicities to human being showing intense stimulus to skin, eyes, mucous membrane and nerve system. It is also known to cause anemia, liver cirrhosis, kidney failure and genetic toxicity in the human being working in the exposed area. LD$_{50}$ of furfural for peritoneal injected mouse has been known around 20mg/kg, but the acute toxicity on aquatic organisms such as fish, daphnid or algae are not well known, compared to those on rodents. In this experiment, we studied on the fish toxicity of furfural using Japanese Medaka (Orvzias latipes) and Common Carp (Cvprinus carpio). We also observed histological changes in the fish organs. The LC$_{50}$ were 12. Smg/L in Japanese Medaka and 21.8 mg/L in Common Carp, respectively. When Common Carps were exposed to 120mg/L of furfural concentration for 30 minutes, blood congestion in gills and lysis of secondary lamella were shown. Though the muscle of caudal fin was not completely eroded, its epidermic cells were shown to be necrotic in various parts. Tissue atrophy and cell necrosis were also shown in the liver of Common Carps exposed to furfural. From these results, furfural seems to cause histological damages on liver, an internal organ as well as on external organs such as gills and fins eventhough the fish were exposed for a short-term.

A 10-year-old, intact female, Maltese dog was presented with a two weeks history of vomiting, anorexia and weight loss. Hematologic analysis revealed mild leukocytosis and increased liver enzyme. Gaseous dilation of small intestine and hyperechoic nodules of hepatic lobes were revealed on the imaging studies. Liver biopsy was performed through laparotomy and histopathologic results revealed liver cirrhosis with precancerous lesions. Two days later, endoscopy was performed and histopathologic results of the specimens taken by endoscopic biopsy showed gastric adenoma. The gastric surgery was not performed by the owner's request. The patient died after 60 days of diagnosis of gastric adenoma. This case describes clinical features, imaging studies, endoscopic features and histopathologic characteristics of gastric adenoma in a Maltese dog.
