Obesity is known as the most common risk factor for non-alcoholic fatty liver disease. Weight loss is needed to prevent liver function damage from progressing to non-alcoholic hepatosteatosis (NASH) and NASH-related liver cirrhosis. The purpose of this study was to observe the recovery of liver function in obese patients with liver dysfunction through traditional Korean obesity treatment. Body weight, liver function levels and renal function levels were examined by prescribing traditional Korean medicine in obese patients with mild elevation of liver function test. Blood tests were conducted at intervals of one month, and it was observed that liver function recovered to the normal range in three patients.

간경화(liver cirrhosis)는 섬유조직의 증식과 재생성 결절 형성의 형태학적인 변화로 2차적으로 간내혈관의 변형 및 간기능의 저하가 나타나는 질병이며, 정맥류, 복수와 부종, 간성뇌증, 간암 등의 합병증 동반을 미연에 방지하는 것이 간경변증 진단 및 치료에 핵심이다. 일반적으로 간 컴퓨터단층영상이 간경변의 진단 및 병기를 결정하는 방법으로 사용한다. 그러므로 본 연구에서는 간경화의 자동 인식을 위하여 PCA와 TIA 알고리즘을 이용한 특징추출을 통하여 간경변의 자동 검출능력을 알아보고, 각 알고리즘간의 성능을 비교하였다. 실험은 학습영상과 테스트영상으로 구분한다. 고유영상을 생성시키기 위한 학습영상으로 정상영상이 사용되고, 테스트영상으로는 간경화영상이 사용된다. 간 CT 영상에서 간의 질병 부위를 균등하게 ROI 설정하고, $50{\times}50$ 픽셀 크기로 영상을 저장하여 실험하였다. 실험결과로 PCA는 간경화 검출율이 35%로 질병 인식으로 부적합하며, TIA 알고리즘의 AGL, TM, MU, EN는 100% 질병 인식력을 나타내어 간경화 자동 진단 인식으로 가능했다. 또한 결과를 임상에 적용하여 간경변의 컴퓨터보조진단으로 활용한다면 영상의학과 의사에게 업무 부담을 줄이고, 일차적 간경변의 스크리닝 도구로서 활용이 가능할 것이다. 그리고 TIA 알고리즘을 활용한 자동진단은 질병 진단의 전단계로서 예비판독의 정보를 제공하며 간경변의 조기 진단 및 예방이 가능다고 판단된다.

Alcoholic and nonalcoholic steaohepatitis is a leading form of chronic liver disease with few biomakers ad treatment options currently available. a progressive disease of NAFLD may lead to fibrosis, cirrhosis, and hepatocellular carcinoma. Recently, we extracted HIMH0021, which is an active flavonoid component in the Acer tegmentosum extract, has been shown to protect against liver damage caused by hepatic dysfunction. Therefore, in this study, we aimed to investigate whether HIMH0021 could regulate steatohepatitis and liver fibrosis during alcoholic or nonalcoholic metabolic process. HIMH0021, which was isolated from the active methanol extract of A. tegmentosum, inhibited alcohol-induced steatosis and attenuated the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) during hepatocellular alcohol metabolism, both of which promote lipogenesis as well as liver inflammation. Treatment with HIMH0021 conferred protection against lipogenesis and liver injury, inhibited the expression of cytochrome P4502E1, and increased serum adiponectin levels in the mice subjected to chronic-plus-binge feeding. Furthermore, in hepatocytes, HIMH0021 activated fatty acid oxidation by activating pAMPK, which comprises pACC and CPT1a. These findings suggested that HIMH0021 could be used to target a TNFα-related pathway for treating patients with alcoholic hepatitis.

I Alcoholic hepatitis is a serious liver disease that may lead to cirrhosis and carcinoma, and the short-term mortality rate is fairly high in severe patients. This study was conducted to develop the instrument of pattern identification for alcoholic hepatitis. We made the pattern identification questionnaire and symptoms indicator through reviewing traditional oriental medical literatures and got advices from the advisor committee with Delphi technique. The advisor committee on this study was organized by 10 professors of internal medicine of oriental medical colleges nationwide. The questionnaire was composed of questions about 6 pattern identification - dampness, heat, liver, spleen, cold and dryness. We gave importance to each symptoms of 6 pattern identification which had been scored on a 5-point scale. We surveyed two groups: 36 male alcoholic hepatitis patients whose Alcohol Use Disorder Identification Test(AUDIT) scores were over 12 and who drank alcohol over 40 g per day were allocated to the hepatitis group. Forty three men who did not drink alcohol were allocated to the normal group. Alcoholic hepatitis had relativities to dampness, heat among cause of disease and liver, spleen among viscera. There were statistical significances between the hepatitis group and the normal group in dampness, heat, liver questionnaire. As a result of this study we suggest that the questionnaire would be effective instruments of pattern identification for alcoholic hepatitis.

Non-alcoholic fatty liver disease (NAFLD) is common in obesity. However, weight reduction alone does not prevent the progression of NAFLD to end-stage disease associated with the development of cirrhosis and liver disease. In a previous experiment, 50% ethanol extract of Acanthopanax senticosus stem bark (ASSB) was found to reduce body weight and insulin resistance in high fat diet-induced hyperglycemic and hyperlipidemic ICR mice. To evaluate the anti-steatosis action of ASSB, insulin-resistant ob/ob mice with fatty livers were treated with ASSB ethanol extract for an 8 week-period. ASSB ethanol extract reversed the hepatomegaly, as evident in reduction of % liver weight/body weight ratio. ASSB ethanol extract also specifically lowered circulating glucose and lipids, and enhanced insulin action in the liver. These changes culminated in inhibition of triglyceride synthesis in non-adipose tissues including liver and skeletal muscle. Gene expression studies confirmed reductions in glucose 6-phosphatase and lipogenic enzymes in the liver. These results demonstrate that ASSB ethanol extract is an effective treatment for insulin resistance and hepatic steatosis in ob/ob mice by decreasing hepatic lipid synthesis.

Chronic exposure to ethanol induces cumulative damage to the liver starting from fatty infiltration to cirrhosis depending on the dose and duration of exposure. The whole process leading to the development of alcoholic liver disease is very complex and the mechanisms involved are not fully understood. Among many experimental animal models, Lieber-DeCarli liquid diet provides moderate to severe pathophysiological outcome depending on the compositional changes. In the present study, we investigated the temporal changes in the early phase hepatic disease in rats fed with standard Lieber-DeCarli diet. Male Wistar rats were fed with Lieber-Decarli ethanol diet for 6 weeks and the liver samples were obtained after 2, 4 and 6 weeks. Mild fatty infiltration was observed in 2 weeks of feeding and it became evident in 4 and 6 week samples. The level of hepatic triglyceride showed a good agreement with the data obtained in the pathological analysis. Feeding mice with ethanol diet resulted in the maturation and translocation of SREBP-1 to nucleus in the liver. Western blot analysis of the pooled liver sample of control and ethanol fed animals showed a clear-cut time-dependent increase in the expression of nSREBP-1. These data provide important information for selecting proper time point in experimental intervention study in the field of drug development for alcoholic liver disease.

Excessive alcohol consumption is one of the critical causative factors leading to alcoholic liver disease (ALD). ALD is characterized by a wide spectrum of liver damage, ranging from simple uncomplicated liver steatosis (fatty liver) to steatohepatitis and liver fibrosis/cirrhosis. It has been believed that the obvious underlying cause for ALD is due to hepatocyte death induced by alcohol itself. However, recent sparkling studies have shown that diverse immune responses contribute to ALD because liver is enriched with numerous immune cells. Especially, a line of evidence has suggested that innate immune cells such as Kupffer cells and natural killer (NK)/NKT cells are significantly involved in the pathogenesis of ALD via production of pro-inflammatory cytokines and other mediators. Indeed, more interestingly, hepatic stellate cells (HSCs), known as a major cell inducing liver steatosis and fibrosis, can be killed by liver NK cells, which could be suppressed by chronic alcohol consumption. In this review, with the view of liver as predominant innate immune organ, we describe the pathogenesis of ALD in which what roles of innate immune cells are and how they are interacting with HSCs.
