동서양을 망라하여 전 세계적으로 비알코올성 지방간(Nonalcoholic fatty liver disease[NAFLD])의 발생률은 증가추세에 있다. NAFLD는 간에 중성지방(triacylglyceride)이 비정상적으로 축적되어 발생하지만, 사람에 따라서는 간조직에 염증반응이 초래되고, 심지어 간경화, 간암으로까지 진행되기도 한다. NAFLD의 원인이 비만, 인슐린내성과 같은 대사증후군과 연관되기는 하지만, 정확한 병리기전은 아직 규명되지 않았다. 따라서, 치료방법도 충분히 개발되지 못하고 있다. 그럼에도 불구하고, NAFLD에 있어 분명한 점은, 예방과 악화방지가 가능하다는 사실이다.

Hepatopulmonary syndrome (HPS) is characterized by a defect in arterial oxygenation that's induced by pulmonary vascular dilatation in the setting of liver disease. Some studies have shown the relationship between the presence of the HPS and the severity of liver disease, but there are only rare cases of HPS inpatient with Child-Pugh class A liver cirrhosis. We report here on a case of a 58 years-old male who suffered from progressive dyspnea for the previous few years. He was diagnosed with alcoholic liver cirrhosis 5 years previously. There was no significant abnormality on the chest radiograph and transthoracic echocardiography, but the arterial blood gas analysis revealed severe hypoxemia. Contrast-enhanced transesophageal echocardiograpy with agitated saline demonstrated a delayed appearance of microbubbles in the left cardiac chambers. Thus, he was finally diagnosed with HPS. This case suggests that we should consider HPS when a patient with compensated liver cirrhosis has unexplained dyspnea.

Persistent sciatic artery (PSA), a rare congenital vascular anomaly, increases susceptibility to aneurysms and accounts for 40-61% of the cases. Here, we describe a case of PSA in a 70-yearold man with a history of alcoholic liver cirrhosis. Bilateral complete PSAs were detected incidentally on computed tomography angiography during evaluation for spontaneous intramuscular bleeding in the thigh due to cirrhosis-related coagulopathy. Selective angiography of the left PSA revealed aneurysmal dilatation and thrombotic occlusion of the PSA, which was partially removed with aspiration thrombectomy. Intramuscular bleeding was succesfully managed with empirical embolization of the deep femoral artery.

Bactericidal activity of normal and cirrhotic patients' sera against Vibrio vulnificus was investigated and compared each other as a part of the pathogenesis study of V. vulnificus septicemia. Bactericidal activity of serum against V. vulnificus was complement-dependent and the alternative pathway played the major role. V. vulnificus strains CDC A1402 and ATCC 27562 appeared serum-sensitive, and CDC C7184, clinical isolate CNUH1 and ATCC 29307 were serum-resistant. When bactericidal activity of cirrhotic sera against serum-sensitive CDC A1402 and serum-resistant CDC C7184 was compared with that of normal sera. showed slightly poorer bactericidal activity than normal sera. Especially in the case of serum-resistant CDC C7184 strain, cirrhotic sera showed statistically significant decrease(p<0.05) in their bactericidal activity.

Purpose: From August 2017, hospice-palliative care (HPC) will be provided to patients with acquired immunodeficiency syndrome (AIDS), chronic obstructive pulmonary disease (COPD), and liver cirrhosis in Korea. To contribute to building a non-cancer (NC) hospice-palliative care model, NC specialists were interviewed regarding the goals, details, and provision methods of the model. Methods: Four physicians specializing in HPC of cancer patients formulated a semi-structured interview with questions extracted from literature review of 85 articles on NC HPC. Eleven NC disease specialists were interviewed, and their answers were analyzed according to the qualitative content analysis process. Results: The interviewees said as follows: It is difficult to define end-stage NC patients. HPC for cancer patients and that for NC patients share similar goals and content. However, emphasis should be placed on alleviating other physical symptoms and emotional care rather than pain control. Timing of the care provision should be when patients are diagnosed as "end stage". Special issues should be considered for each NC disease (e.g., use of anti-retroviral drugs for AIDS patients, oxygen supply for COPD patients suffering from dyspnea, liver transplantation for patients with liver cirrhosis) and education should be provided to healthcare professionals. NC patients tend to negatively perceive HPC, and the government's financial assistance is insufficient. Conclusion: It is necessary to define end-stage NC patients through in-depth discussion to minimize issues that will likely accompany the expansion of care recipients. This requires cooperation between medical staff caring for NC patients and HPC givers for cancer patients.

In this paper, we studied possibility about application for CAD on diffuse liver disease through pixel texture analysis parameters(average gray level, skewness, entropy) which based statistical property brightness histogram and image analysis using brightness difference liver and kidney parenchyma. The experiment was set by ROI ($50{\times}50$ pixels) on liver ultrasound images.(non specific, fatty liver, liver cirrhosis) then, evaluated disease recognition rates using 4 types pixel texture analysis parameters and brightness gap liver and kidney parenchyma. As a results, disease recognition rates which contained average brightness, skewness, uniformity, entropy was scored 100%~96%, they were high. In brightness gap between liver and kidney parenchyma, non specific was $-1.129{\pm}12.410$ fatty liver was $33.182{\pm}11.826$, these were shown significantly difference, but liver cirrhosis was $-1.668{\pm}10.081$, that was somewhat small difference with non specific case. Consequently, pixel texture analysis parameter which scored high disease recognition rates and CAD which used brightness difference of parenchyma are very useful for detecting diffuse liver disease as well as these are possible to use clinical technique and minimize reading miss. Also, it helps to suggest correct diagnose and treatment.

A 5-year-old, intact female Shih-Tzu dog was presented with 1 year history of icterus, ascites and anorexia. The serum biochemistry revealed elevated liver enzyme levels. Microhepatica and decreased serosal detail were detected in abdominal radiography. Abdominal ultrasonographic findings included irregular liver margins, multifocal hypoechoic nodules in the liver parenchyma, and ascites. Computed tomography (CT) showed multifocal hypodense nodules with ring-like contrast enhancement. Cytologic and histopathologic examination by liver core biopsy revealed fibrosis. Cirrhosis was diagnosed based on above results. This report focuses on the imaging characteristics of ultrasonography and CT for liver cirrhosis in a dog.

HCV is a single-stranded RNA virus and more than 1 million new cases are reported annually worldwide. The six major HCV genotypes and numerous subtypes vary in their geographic distribution. It is thought that genetic heterogeneity of HCV may account for some of the differences in disease outcome and response to treatment observed in HCV infected persons. In this study, we determined HCV genotypes among chronic Korean HCV patients and evaluated direct sequence PCR protocols developed. For the study, 232 chronic HCV patient sera were used. HCV RNA was extracted and two pairs of consensus PCR primers were selected in 5'UTR region for amplification of HCV RNA. Amplification products obtained from the HCV positive cases were subjected to automatic sequencing. Sequences were compared with those in GenBank by using the BLAST program. From this study, five HCV genotypes, 1b, 2a, 2b, 2c and 3a were found. HCV genotypes 4, 5 and 6 were not determined. HCV genotype 1b (53.9%, 125/232) and 2a (35.8%, 83/232) were most frequently found. This group was followed by 2b (3.9%, 9/232), 3a (3.4%, 8/232) and 2c (3.0%, 7/232). The data presented here suggest a complex distribution of HCV types and they were well correlated with other reports on Koreans and will be helpful for type-specific follow-up of Korean HCV patients. This study showed that 5'UTR direct sequence analysis is a sensitive and rapid method to identify HCV genotypes.
