Anorexia, nausea, and vomiting are one of the most frequent symptoms in viral hepatits patients. These may be due to poorly detoxified substances by dysfunctioned hepatocytes or by gastritis, but the pathophysiology is not totally understood. The symptoms interfere with adequate nutrient intake and are managed by metoclopramide, which accelerates gastric emptying. Thus delayed gastric emptying may well be a contributing factor to such symptoms. To determine such a relationship, we measured gastric emptying time in 11 normal subjects,9 acute (AVH), and 12 chronic B viral hepatitis (CVH) patients. All were males with a mean age of 23 years. An egg was labeled with 0.5 mCi of $^{99m}Tc-sulfur$ colloid, fried, then eaten between 2 slices of bread with 100 cc of water. Anterior and posterior images were taken at 20 minute intervals over a 2 hour period. A geometric mean of activity pertaining to the gastric region was measured, and $T_{1/2}$ was calculated from the time activity curve. $T_{1/2}$ for normal the group was $57.8{\pm}6.3$ minutes while that for the AVH and CVH group was $58.2{\pm}8.2$ (p=0.40) and $64.1{\pm}10.5$ (p=0.09), respectively. There was 1 AVH Patient and 4 CVH patients with prolonged $T_{1/2}$. Anorexia and nausea was seen in 71% and 46% of the patients, respectively. 80% and 60% of the patients with prolonged $T_{1/2}$ had anorexia and nausea, respectively.

Armillaria tabescens, one of edible and medicinal mushrooms belonging to Agaricales of Basidiomycota, has been known to have outstanding curative effects on chronic hepatitis and cholecystitis and inhibitory effects on the sarcoma 180 and Erhrlich carcinoma of mice. Neutral saline soluble (0.9% NaCl), hot water soluble and methanol soluble substances (hereinafter referred to Fr, NaCl, Fr. HW and Fr, MeOH, respectively) were extracted from fruiting body of the mushroom. In vitro cytotoxicity tests showed that crude polysaccharides were not cytotoxic against cancer cell lines such as NIH3T3 and Sarcoma 180 at the concentration of $2000\;{\mu}g/ml$. Intraperitoneal injection with crude polysaccharides exhibited life prolongation effect of $28.8{\sim}46.5%$ in mice inoculated with Sarcoma 180, respectively. Fr. NaCl improved the immunopotentiation activity of B lymphocyte by increasing the alkaline phosphatase activity by $1.8{\sim}2.1$ folds, respectively. In case of Fr, NaCl, the numbers of peritoneal exudate cells and circulating leukocytes were increased by 9 and 1.9 folds, respectively.

The oxidative damage of lipids, protein, and DNA is known to be involved in not only chronic inflammations such as arthritis, hepatitis, nephritis, gastritis, colitis, and periodontitis but also metastasis. It has given impetus to searching for natural compounds without toxicity, which prevent the development of these diseases. The direct scavenging effects of aged black garlic extract (ABGE) were evaluated in vitro on DPPH radical, hydroxyl radical, hydrogen peroxide, and genomic DNA damage related to oxidative stress. Furthermore, its antioxidant effect on lipid peroxidation was investigated in human fibrosarcoma cells (HT1080), which were exposed to the hydroxyl radical generated by the Fenton reaction. It was observed that ABGE exhibited a greater inhibitory effect on hydrogen peroxide than other reactive oxygen species, and also blocked DNA oxidation and lipid peroxidation induced by the hydroxyl radical. The oxidative stress in live cells was also inhibited in the presence of ABGE. In addition, its inhibitory effects on the activity and expression of MMP-2 and -9 related to metastasis were determined using gelatin zymography and western blot. The data showed that it inhibited MMP-2 and -9 in PMA-stimulated HT1080 cells. Therefore, these results suggest that ABGE show potential as an excellent agent for prevention of metastasis related to oxidative stress.

Objectives : The purpose of this study was to determine correlation between coping strategies to disease and quality of life in chrome viral B hepatitis patients ; to investigate difference of coping strategies to disease and quality in life between chronic viral B hepatitis patients and normal persons ; and to identify major variables related to quality in life of chronic viral B hepatitis patients. Methods: The authors used Weisman coping strategy scale for measuring coping ability and efficacies, and the questionnaire for measuring quality of life including physical, psychological, social and economical aspects and satisfaction of sexual life was made by authors based on related literatures. Data were collected through questionnaire survey over a period from Sep 15, 1994 to Nov 11, 1994. Subjects served for this study consisted of 94 chronic viral B hepatitis patients visited to department of internal medicine at one general hospital and 100 normal persons visited to one general hospital for routine check up of health. The collected data were analyzed by SAS and the statistical methods for analysis were Chisquare, t-test and multiple regression analysis. Results : 1) It was revealed that coping strategies to disease significantly correlated to individual's quality of life. 2) There was no significant difference in coping strategies to disease between chronic viral B hepatitis patients and normal persons. However, chronic viral B hepatitis patients showed the lower scroes of quality of life in physical, psychological and economical aspects. 3) The most important variables which were influenced upon quality of life were coping strategies to disease and satisfaction of sexual life. That is, the more active coping strategies to diseases and the higher satisfaction of sexual life, consequently the higher quality of life was. Especially male patient group or normal persons showed each other the higher scores of quality of life in physical and psychological area than female group or patient group. 4) No statistically significant difference in coping strategies to disease and quality of life was found between HBeAg positive group and HBeAg negative group. Conclusions : The authors suggest that chronic viral B hepatitis patients may show the lower score of quality of life than normal person. Therefore, quality of life assessment should become an integral part of all clinical area that seek to assess the effectiveness of treatment. Also, through the interdisciplinary approach, a comprehensive paradigm that can better account for the effects of chronic disease on the individual' s quality of life should be developed.

The leaves of Selaginella tamariscina were used for the treatment of many diseases in traditional medicine. In the study, antioxidant, anti-inflammatory, and wound healing activities of the hot-water extract(STW) and 80%ethanol extract(STE) obtained from S. tamariscina were evaluated. As a result, the polyphenol content of STW and STE were 38.108±0.766 mg/g and 17.927±1.064 mg/g, respectively. The DPPH and ABTS radical scavenging activities with the IC50 values of the STW were over 2 times lower than that of the STE. In the MTT assay, RAW264.7 cell viability of two extracts was decreased by about 6% at 1 mg/mL, whereas for HaCaT cell viability increased by 18% at 50 ㎍/mL. In addition, STW and STE suppressed the production of nitric oxide(NO), Tumor-necrosis(TNF)-��. COX-2 and PGE2 in lipopolysaccharide(LPS) induced RAW264.7 cells. Furthermore, the STE showed wound healing effect through the promotion of skin cell migration in TNF-�� stimulated human keratinocytes. These results indicated that the STW and STE have the potential to be used as a new cosmetic active ingredients in skin care.

Transarterial chemoembolization (TACE) is a commonly used and rapidly evolving non-invasive treatment for hepatocellular carcinoma (HCC). It is important that understanding individual anatomical variants and planning for tumor-feeding artery access to acquire adequate treatment effectiveness. In this study, we will report acquired arteriovenous malformation which interferes with TACE for HCC. A 72-year-old man with persistent abdominal pain for 2 days visited our hospital. The patient was chronic hepatitis B carrier and had a history of HCC treated with conventional TACE 10 years ago. Hypervascular nodular HCC in the liver segment 8 and aberrant right hepatic artery from the superior mesenteric artery were detected on computed tomography (CT). When first TACE was performed, the tumor-feeding artery originating from the left hepatic artery was found and embolized. There was no tumor-feeding artery from the right hepatic artery but arteriovenous malformation was found. After a month, follow up CT showed necrotic lesion and residual HCC and we performed secondary TACE. On secondary TACE, we selected the right hepatic artery and passed through arteriovenous malformation. Superselective-angiogram showed remnant tumoral staining and remnant tumor was embolized using drug-eluting bead and Adriamycin. Final angiogram showed no remnant tumoral staining and the patient was discharged without complication. We found the rare case of arteriovenous malformation adjacent to HCC, and we performed superselective TACE beyond arteriovenous malformation to treat HCC.

Background : The prevalence of chronic hepatitis C virus (HCV) tends to be higher in the elderly. Pegylated interferon and ribavirin therapy (Peg-IFN/RBV) was recommended as the first-line treatment in the past decades, but this regimen showed unsatisfactory results in terms of safety and efficacy especially in elderly patients. Recently, it was demonstrated that dual therapy with daclatasvir and asunaprevir was well tolerated and led to high sustained virological response (SVR) rates, irrespective of age. We conducted a study to evaluate the efficacy and safety of daclatasvir plus asunaprevir by involving elderly patients aged above 65 years. Methods : We retrospectively analyzed clinical data from chronic hepatitis C virus (HCV) genotype 1b patients treated with daclatasvir plus asunaprevir from September 2015 to December 2016 at Seoul St. Mary's hospital. The patients were divided into two groups as elderly patients (older than 65 years) and non-elderly patients (younger than 65 years) and compared the efficacy and safety. Results : A total of 112 patients were treated with daclatasvir plus asunaprevir for chronic hepatitis C. Among them, 101 patients completed the whole treatment, and in 88 patients the amount of HCV RNA was measured after 12 weeks of treatment. There was no significant difference in SVR at 12 weeks between both the groups (p=0.68). Typically, 91.4%(32/35) of elderly patients and 94.3%(50/53) of non-elderly patients achieved SVR12. Common adverse events included elevation in transaminase level, headache, and gastrointestinal disorders. There was no statistical difference in the symptoms between the two groups. Conclusions : The combination therapy with daclatasvir plus asunaprevir exhibited similar rates of SVR12 in HCV elderly patients without leading to further adverse events compared to non-elderly patients. Therefore, it is proposed that daclatasvir plus asunaprevir therapy could be considered as an effective and safe treatment, even in patients aged over 65 years.

Purpose: The aim of this study is to evaluate the effective role of living-related liver transplantation (LRLT) on posttransplant linear growth in children. Methods: Thirty six children were enrolled who received LRLT at Asan Medical Center from December, 1994 to February, 1999 and showed more than one-year postoperative survival. Mean height standard deviation score (zH) was analyzed according to medical records including heights during pretransplant and posttransplant follow-up periods. Results: zH of total children showed significant linear growth after LRLT from -1.58 to 0.33 at 24 posttransplant month (p<0.05). zH in children under 6 years of age, to exclude the effect of adolescent linear growth spurt, showed increment in height (p<0.05). Linear growth of children with liver cirrhosis improved and that with fulminant hepatitis was matained same. While stunted children (mean zH=-2.30) achieved good catch-up growth after transplantation, children with normal growth remained same. Children with significant hepatic dysfunction after LRLT such as chronic rejection or posttransplant lymphoproliferative disorder showed retarded posttrasplant linear growth. There was no statistical difference according to the type of immunosuppressants. Conclusion: LRLT resulted in adequate or catch-up linear growth in children with acute, chronic and metabolic liver disease. Successful LRLT suggested to be a promising option not only in long term survival but also in normal linear growth.

This study was to investigate the protective and anticirrhotic effects of Mockhyangjokisan and Haewooljoweetang on the liver cirrhosis or fibrosis induced by prolonged bile duct ligation; a new experimental model for cirrhosis and the intraperitoneal injection of dimethylnitrosamine in the rat. The development of fibrosis or cirrhosis and its inhibition by the two prescriptions were examined by the chemical analysis of AST, ALT, and hydroxyproline. The results obtained were as follows. 1. The increase of serum asparate aminotransferase induced by bile duct ligation was inhibited by the administration of Mockhyangjokisan and Haewooljoweetang extract. 2. The increase of serum alanine aminotransferase induced by bile duct ligation was inhibited by the administration of Mockhyangjokisan and Haewooljoweetang extract. 3. The increased level of serum AST and AL T induced by the intraperitoneal injection of dimethylnitrosamine was inhibited by the administration of Mockhyangjokisan and Haewooljoweetang extract. 4. The increasing level of hydroxyproline volume in the damaged liver tissues in the rat was decreased by the oral administration of Mockhyangjokisan and Haewooljoweetang extract. But there were no significant differences in the inhibition rate between the two experimental groups.
