To investigate the cognitive degree about hepatitis and hepatosis, 916 subjects are examined with query and hepatotitis B, C, E test as well as s-AST and s-ALT as liver function test. Based on results, there are 4.9% of positive hepatitis and 8.9% of hepatosis and 13.8% of liver disorder. Among positive hepatitis, there are 93.3% of type B, 42.2% of type E and 6.7% of type C, respectively. From 45% of positive hepatitis B, they carry hepatitis B and E together. The cognitive degree about positive hepatitis is 64.4%, hepatosis 8.6%. The knowledge degree from cognitive group is higher than that of noncognitive group but there is no difference from hepatosis between two groups (p<0.001). The cognitive degree of liver disorder depends on academic background (p<0.001), mother's academic background (p<0.001), job (p<0.05) and family's income (p<0.001), showing significant difference. In summary, hepatitis carrier aware quite well about liver disorder but very low from hepatosis. Accordingly, the plan to increase a cognitive degree and continuous education as well as policy support to minimize spread of disease and to protect not to be worsen disease will be needed.

Objectives: We checked hepatitis A virus antibody(anti-HAV IgG) and hepatitis B virus antibody(HBsAb) in three large companies. The result could be a guideline to establish proper health policy for Hepatitis A and B virus preventive plan in company. Methods: We investigated the seroprevalence of anti-HAV IgG and HBsAb, and demographic characteristics of employee volunteer in three companies in southern area of Korea. Company was divided three according to health policy for hepatitis A and B. Results: The seroprevalence rate of anti-HAV IgG in company A, B, and C was 53.6%, 25.8%, and 17.7%(P<0.001), respectively. The seroprevalence rate of HBsAb in workplace A, B, and C was 79.7%, 82.4%, and 70.9%(P<0.001), respectively. Anti-HAV IgG showed more considerable difference among the companies. Conclusions: The results confirmed that low rate of IgG anti-HAV and HBsAb, particularly in the company that had low level of hepatitis education and vaccination program. This study was important for establishing hepatitis education policies, to prevent and control outbreaks in companies.

Acute hepatitis is caused by virus, alcohol. toxins and drugs. Clinical symptoms of acute hepatitis are severe fatigue, jaundice, nausea, hepatomely, lymphadenopathy. We encountered two cases of acute hepatitis, one C type viral hepatitis and the other hepatitis by overuse of medicine. The symptoms of the latter are severe fatigue, petechia and heartburning. The symptoms of the latter are severe fatigue, nausea, dyspepsia, yellow urine and skin. We recognized that total bilirubin. direct bilirubin, serum transaminase, alkaline phosphatase and gamma glutamyl transferase were elevated. We treated both patients with herb medicine(Gagamsaenggan-tang). Gagamsaenggan-tang has been used to hepatic diseases and have been known to have beneficial effects. The patients' symptoms began to improve after about two weeks of treatment. After 3 weeks on medication, the clinical symptoms and liver function of two patients were improved.

Korea is an endemic area of chronic hepatitis in the world. Liver cirrhosis and liver cell carcinoma, presumed to be related to such chronic hepatitis, are the major causes of death in this country. The purpose of this study is disclosing the sources of chronic hepatitis in Korea establishing its histologic characteristics, disclosing the patterns of progression in chronic hepatitis, delineating its prognosis and finally speculating its etiology. The study group was composed of 183 patients with biopsy-proven acute icteric viral hepaticis, 32 patients with biopsy- proven anicteric hepatitis and 260 patients with biopsy- proven chronic hepatitis. These patients submitted to long-term follow-up by means of liver needle biopsy and/or clinicolaboratory evaluation. The period of follow-up ranged from two months to 18 years. The histological features of the initial biopsy specimens of chronic hepatitis permitted a division of the cases cases into the following five types: Type I. Persisting portal hepatitis : so called persisting hepatitis 43 Type II. Chronic inactive hepatitis with incomplete strand septal fibrosis. This type has thin fibrotic septation in addition to Type I with portal sclerosis 38 Type III. Chronic active periportal hepatitis(CAPH) : so called aggressive hepatitis, characterized by marked piecemeal necrosis. This type has been subdivided further into three groups: AB and C on the basis of histologic features. A CAPH without cirrhosis 15 B CAPH with cirrhosis 99 C CAPH with diffuse acinus type parenchymal nodules; characterized by rosette-forming micronodules 21 Type IV. Subacute hepatic necrosis; characterized by multilobular and/or bridging necrosis. 14 Type V. Persisting lobular hepatitis; characterized by spotty necrosis, which looks very similar to acute viral hepatitis. Such histologic changes should be persisted for more than six months 30 In Korea the main source of chronic hepatitis is the anicteric type. Of the chronic hepatitis observed in the hospital, Type IIIb was the most frequent in its incidence and occasionally exhibited development of hepatocellular carcinoma, but the mortality was highest in Type IIIc during the period of follow-up. Histologic characteristics of these five types suggest a spectrum of chronic hepatitis in Korea from an early and mild stage to advanced and fatal cirrhosis, which is occasionally associated with primary hepatic cell carcinoma. It seems that Type IV can be followed by flare-up of various stages of acute and chronic hepatitis with HBsAg and that many cases of liver cirrhosis prevalent in Korea occur through such an active process of Type IV. The etiology is not established, but in Korea it is mainly related to HBsAg.

Purpose: Non-A, B, C viral hepatitis is the name given to the disease with clinical viral hepatitis, but in which serologic evidence of A, B, C hepatitis has not been found. Little is known about the etiology and clinical features of non-A, B, C viral hepatitis in children. Methods: A clinical analysis of 45 cases with non-A, B, C viral hepatitis who were admitted to the Department of Pediatrics, Pusan National University Hospital, from January 2001 to June 2004 was carried out retrospectively. Patients who were positive for HBsAg, anti-HAV and anti-HCV and had toxic, metabolic, autoimmune, or neonatal hepatitis were excluded in this study. Results: Among 45 cases of non-A, B, C viral hepatitis, the etiology was unknown in 26 (57.8%), CMV (cytomegalovirus) in 14 (31.1%), EBV (Epstein Barr virus) in 2 (4.4%), HSV (herpes simplex virus) in 2 (4.4%) and RV (rubella virus) in 1 (2.2%). Twenty seven out of 45 (60.0%) patients were under 1 year of age. Sixteen (33.3%) patients had no specific clinical symptoms and were diagnosed incidentally. On physical examination, twenty seven out of 45 patients (60.0%) had no abnormal findings. Forty three out of 45 patients (95.6%) showed classic clinical course of acute viral hepatitis, whereas fulminant hepatitis developed in two patients. Mean serum ALT (alanine aminotransferase) level was $448.7{\pm}771.9IU/L$. Serum ALT level was normalized in 31 out of 45 patients (81.6%) within 6 months and all patients within 18 months. Aplastic anemia was complicated in a case. Conclusion: Although most patients with non-A, B, C viral hepatitis showed a good prognosis, a careful follow-up would be necessary because some of them had a clinical course of chronic hepatitis, fulminant hepatitis and severe complication such as aplastic anemia.

Hepatocellular carcinoma (HCC) related to hepatitis B virus (HBV) and hepatitis C virus (HCV) infections is thought to account for more than 80% of primary liver cancers. Both HBV and HCV can establish chronic liver inflammatory infections, altering hepatocyte and liver physiology with potential liver disease progression and HCC development. Cyclophilin A (CypA) has been identified as an essential host factor for the HCV replication by physically interacting with the HCV non structural protein NS5A that in turn interacts with RNA-dependent RNA polymerase NS5B. CypA, a cytosolic binding protein of the immunosuppressive drug cyclosporine A, is overexpressed in many cancer types and often associated with malignant transformation. Therefore, CypA can be a good target for molecular cancer therapy. Because of antiviral activity, the CypA inhibitors have been tested for the treatment of chronic hepatitis C. Nonimmunosuppressive Cyp inhibitors such as NIM811, SCY-635, and Alisporivir have attracted more interests for appropriating CypA for antiviral chemotherapeutic target on HCV infection. This review describes CypA inhibitors as a potential HCC treatment tool that is contrived by their obstructing chronic HCV infection and summarizes roles of CypA in cancer development.

Purpose: This study was to identify factors predicting the occurrence of depression among patients with hepatitis C treated with Peg-interferon. Methods: The subjects were 134 patients treated with Peg-interferon after the diagnosis with hepatitis C at the D University Hospital and 3 hospitals located in Busan, South Korea. The predictors of depression were identified by measuring the general characteristics of the subjects and their disease-related characteristics, social support, sleep disorders, and degree of side effects by interferon. The data were analyzed with a t-test, ANOVA, and logistic regression using the SPSS/WIN 18.0 program. Results: Sixty-six point four percent of the subjects suffered from mild to more severe depression. Fatigue, hair loss, itching, and sleep disorders turned out to be significant predictors. In addition, the explanatory power of these variables for the occurrence of depression was 70%. Conclusion: Sleep disorders and drug side effects were determined to have significant influence on the development of depression in hepatitis C patients treated with Peg-interferon. Therefore, the development of nursing intervention programs aimed to prevent depression by effectively managing sleep disorders and side effects is mandated in future to help the given population.

Objectives: The present study aimed to provide clinical evidence on the effect of herbal medicine on the treatment of hepatitis C using a systematic review and meta-analysis of randomized controlled trials (RCTs). Methods: This study included RCTs that verified the effects of herbal medicine for the treatment of hepatitis C. A literature search of English, Chinese, and Korean databases was performed, and the selected literature was assessed to investigate the risk of bias. Results: The analysis included 14 RCTs. The total effective rate was the most commonly used outcome measure. The meta-analysis revealed that the total effective rate and total bilirubin difference were higher and that the recurrent rate was lower in the herbal medicine group than in the western medicine group (RR: 1.20, 95% CI: 1.06-1.35, p=0.003, I2=52; MD: 0.52, 95% CI: -0.62 to 1.66, p=0.37, I2=0; RR: 0.35, 95% CI: 0.11-1.09, p=0.07, I2=0). The included RCTs had relatively poor quality and a small sample size. Conclusion: Treatment with herbal medicine was found to be partially effective in treating hepatitis C. The included RCTs had relatively poor quality and a small sample size. This study can serve as a foundation for further clinical studies on the development of treatment methods for hepatitis C based on herbal medicine.
