CD8+T cells are key factors mediating hepatitis B virus (HBV) clearance. However, these cells are killed through HBV-induced apoptosis during the antigen-presenting period in HBV-induced chronic liver disease (CLD) patients. Interferon-inducible protein 6 (IFI6) delays type I interferon-induced apoptosis in cells. We hypothesized that single nucleotide polymorphisms (SNPs) in the IFI6 could affect the chronicity of CLD. The present study included a discovery stage, in which 195 CLD patients, including chronic hepatitis B (HEP) and cirrhosis patients and 107 spontaneous recovery (SR) controls, were analyzed. The genotype distributions of rs2808426 (C > T) and rs10902662 (C > T) were significantly different between the SR and HEP groups (odds ratio [OR], 6.60; 95% confidence interval [CI], 1.64 to 26.52, p = 0.008 for both SNPs) and between the SR and CLD groups (OR, 4.38; 95% CI, 1.25 to 15.26; p = 0.021 and OR, 4.12; 95% CI, 1.18 to 14.44; p = 0.027, respectively). The distribution of diplotypes that contained these SNPs was significantly different between the SR and HEP groups (OR, 6.58; 95% CI, 1.63 to 25.59; p = 0.008 and OR, 0.15; 95% CI, 0.04 to 0.61; p = 0.008, respectively) and between the SR and CLD groups (OR, 4.38; 95% CI, 1.25 to 15.26; p = 0.021 and OR, 4.12; 95% CI, 1.18 to 14.44; p = 0.027, respectively). We were unable to replicate the association shown by secondary enrolled samples. A large-scale validation study should be performed to confirm the association between IFI6 and HBV clearance.

A congenital portosystemic shunt is a very rare portosystemic vascular anomaly which leads to jaundice, hypoglycemia, hyperammonemia, liver cirrhosis, hepatic coma, and pulmonary hypertension. Anatomically, portosystemic shunts are divided into intra- and extrahepatic shunts. Congenital intrahepatic portosystemic shunts are rare anomalies, and the early diagnosis is important to prevent hepatic encephalopathy and hypoglycemia. We report a case of an infant with symptoms of heart failure due to a congenital intrahepatic portosystemic shunt and a ventricular septal defect (VSD), which were treated successfully with four coil embolizations and open heart surgery for the VSD.

Obtaining an available information on health concerns of parents of school-age children and furthermore developing the sound policy for the public on health education, this study was conducted during Nov.-Dec. 1985 in the four selected areas; Seoul, large, middle and small city, and farming and fishery villages for 3,337 parents of schoolchildren in Korea. In this study, parents complected a questionnaire containing 34 items related to health concerns(e.g. drinking alcohol, air pollution, cancer, etc. see Table 4 and Fig. 2). For each health items, respondents were asked to indicate a choice between three levels of concern; 'Very high concern,' 'Moderate concern,' 'Little concern', and 'No opinion'. An analysis of responses indicated that most of the top ten health concerns identified by parents as cancer, abortions among high school students, medical malpractice, water pollution, traffic accidents, air pollution, suicide of parents and homicide of offspring, heart disease, venereal diseases, and high blood pressure in that order. Those health problems about which respondents were least concerned were more closely related to the individual, such as drinking alcohol, smoking, tooth decay, gum disease, underweight, overweight. Of greater concern were more such as water pollution, abortions among high school students, air pollution, accidents, medical malpractice. For cancer, heart disease, high blood pressure, various accidents, environmental pollution, parents showed high concern, however, for health issues which contributed as causative influences such as lung cancer from smoking and liver cirrhosis and traffic accidents from drinking alcohol showed less concern. Relationship between parent's residential areas, educational level and sex distribution and health concern showed little difference, however, for these issues parents identified as relatively high concern. Most parents stowed more concern in sex-related of family-related health issues such as abortions among high school students, suicide of parents and homicide of offspring.

Congenital interruption of the inferior vena cava (IVC) can lead to secondary hepatic congestion, portal hypertension, and liver cirrhosis. A 49-year-old woman was admitted to the gynecology department with symptoms of menorrhalgia, known uterine myoma, and anemia. Abdominal computed tomography (CT) and venography performed at our hospital revealed congenital interruption of the IVC. The patient underwent retrohepatic cavoatrial bypass surgery with a polytetrafluoroethylene (PTFE) 16-mm ringed graft via posterolateral thoracotomy, and recovered without major complications. A retroperitoneal approach via posterolateral thoracotomy provides appropriate visualization during dorsal cavoatrial bypass in treating patients with congenital interruption of IVC.

Klinefelter's syndrome is the most common congenital abnormality that causes primary hypogonadism. It is associated with diseases that predominantly affect women, such as systemic lupus erythematosus (SLE), and it can sometimes cause veno-occlusive disease. We experienced a case of Budd-Chiari syndrome (BCS) in a 33-year-old man with Klinefelter's syndrome presented with hematemesis and edema in both lower extremities. The clinical and laboratory findings were compatible with SLE, antiphospholipid syndrome, and BCS. To the best of our knowledge, this is the first case report to describe a simultaneous presentation of these four clinical syndromes in a single patient.

Objectives : The aim of this study was to characterize the effect of Injinchunggan-tang on $TGF-{\beta}1-induced$ hepatic fibrosis. Methods : mRNA and protein expression levels of $TGF-{\beta}1$ in Injinchunggan-tang-treated HepG2 cells were compared to untreated cells using quantitative RT-PCR and ELISA assay, respectively. mRNA expression levels of the TGF-1 pathway genes (TR-1, TR-II, Smad2, Smad3, Smad4, and PAI-1) and fibrosis-associated genes (CTGF, fibronectin, and collagen type 1) were evaluated by quantitative RT-PCR. The effect of Injinchunggan-tang on cell proliferation of T3891 human fibroblast was evaluated using [$^3H$]thymidine incorporation assay. Results : Expression of $TGF-{\beta}1$ mRNA and protein was inhibited by Injinchunggan-tang in a dose- and time-dependent manner. Whereas $TGF-{\beta}1-mediated$ induction of PAI-1 was suppressed by Injinchunggan-tang, expression of the $TGF-{\beta}1$ pathway genes such as TR-1, TR-II, Smad2, Smad3, and Smad4 was not affected by Injinchunggan-tang treatment. Injinchunggan-tang was found to inhibit $TGF-{\beta}1-induced$ cell proliferation of T3891 human fibroblast, and also abrogated $TGF-{\beta}1-mediated$ transcriptional up-regulation of CTGF, fibronectin, and collagen type I. Conclusions : This study strongly suggests that the liver cirrhosis-suppressive activity of Injinchunggan-tang may be derived at least in part from its inhibitory effect on $TGF-{\beta}1$ functions, such as blockade of $TGF-{\beta}1$ stimulation of fibroblast cell proliferation and fibrosis-related gene expression as well as expression of $TGF-{\beta}1$ itself.

Objective : The aim of this study is to investigate the effect of Injin fractions on hepatic fibrosis induced by $TGF-{\beta}1$. Method : $TGF-{\beta}1$ mRNA, protein, $TGF-{\beta}1$ receptor, Smad family and PAI-I mRNA were studied in HepG2 cell, and the proliferation, connective tissue growth factor, fibronectin and collagen type I mRNA in T3891 fibroblast by quantitative RT-PCR, ELISA and thymidine incorporation assay. Results : On $TGF-{\beta}1$ mRNA and protein synthesis in HepG2, $H_2O$, butanol and hexane fractions of Injin showed inhibitory effect in a dose-dependent way. In the study on $TGF-{\beta}1$ receptor, Smad family and PAI-1 mRNA in HepG2, $H_2O$, butanol and hexane fraction of Injin showed inhibitory effect on the expression of PAI-1 in a dose-dependent way. On the proliferation of T3891 fibroblast induced by $TGF-{\beta}1$, $H_2O$, ethylacetate and butanol fractions of Injin showed inhibitory effect. In the study on the factors affected by $TGF-{\beta}1$, $H_2O$, ethylacetate and butanol fractions of Injin showed inhibitory effect on CTGF, and $H_2O$, butanol, chloroform and hexane fractions showed inhibitory effect on the expression of collagen type I, whereas no fraction showed inhibitory effect on the expression of fibronectin Conclusion : These results show that each fraction of Injin acts as a fibrosis inhibitory factor by itself or in combination, ultimately inhibiting liver cirrhosis.

Diseases caused by indurate tissues of the internal organs are liver cirrhosis and abdominal sclerosis. The cause of chronic gastro-intestinal disease is a digestive system disorder and a defecation disorder. They impede peristaltic movement and digestive system with the symptom that indurate tissues. The purpose of the present study was to determine the disease grade quantitatively by measuring an indurated standard of tissues and organs. For the measurement of elasticity, we designed the system that measure the displacement of the substance and approved pressure using ultrasound transducer. For verification of developed system, we compared elasticity as results of experiment between the developed system and public elasticity measurement machine at individual plastic phantoms made by plastic hardener and softener. Elasticity of the plastic phantoms is averagely 0.007MPa lower measured by developed system than Micro-indenter, and less than 10% errors. Comparing with economical value and accuracy between developed system and Micro-indenter, the system is significant of measurement for tissue elasticity. Thus, it is possible to measure a elasticity at human tissue and organ. A chronic gastro-disease as well as grade could be decided objective validity using this system.

Hepatic disease has been noted and reported for involvement various detrimental factors. Among many detrimental injury factors, alcohol has been noted for hepatitis, fatty liver, fibrosis, and hepatic cirrhosis. The purpose of this study is to develop animal model for hepatic fibrosis in pig with ethanol, and to search new anti-fibrogenic agent. Twelve male Landrace pigs were divided into 3 groups of 4 animals each. Group 1, 2 and 3 were fed with ceramic water only, ceramic water + liquid diet containing 20％ ethanol and normal tap water + containing 20％ ethanol for 12 weeks, respectively. At week 12, all pigs were immediately sacrificed for collection each tissue and blood. Serologically, serum ALT and AST levels were significantly reversed in group 2, comparing to group 3. They were normal range in pigs of group 1. Microscopically, macrovesicular lipid droplets and moderate necrosis were evident in the tap water + ethanol fed group 3. However, ceramic water intake group 1 showed normal. Moreover, in group 3, little fatty changes and mild necrosis were observed. Collagen fibers were detected in the spaces of surrounding periportal and interlobular areas in the group 3 of tap water + ethanol, but collagen synthesis and its thickness of fibrotic septa connecting portal tracts was markedly reduced in the group 2 of ceramic water + ethanol. In immunohistochemistry, myofibroblasts were detected in the ethanol and tap water treated group 3. No or a few myofibroblasts were observed in groups 1 and 2. CYP 2E1 was rarely detected in group 1 fed ceramic water. However, group 2 showed slightly activation of CYP 2E1 in the area of pericentral, while CYP 2E1 was significantly activated in group 3 fed tap and ethanol. Taken together above, alcohol fibrosis model in pig was established. Furthermore, ceramic water had an inhibitory and protecting ability for alcohol-induced hepatic damages.
