Acute hepatitis A is a generally self-limiting disease of the liver. Acute renal failure is rare in patients with acute non-fulminant hepatitis A Acute tubular necrosis is the most common form of renal injury found in such patients. The 215 years old male patient visited our hospital with complaint of general weakness, fatigue, nausea, vomiting and myalgia. He was diagnosed with acute renal failure associated with acute non-fulminant hepatitis A We report here on a case of acute renal failure associated with non-fulminant hepatitis A, and we include a review of the literature.

CJ-50005 is a hepatitis A vaccine which is prepared by formalin inactivation of the HM175 virus cultured in human diploid MRC-5 cells. The general pharmacological properties of CJ-50005 were evaluated in various animals and in vitor system. CJ-50005 at the doses of 0.025, 0.25 and 0.75 $\mu\textrm{g}$/kg, i.m. had no effect on general behavior in mice, chemo- and electro-convulsions in mice, writhing syndrome induced by acetic acid in mice, the barbital sleeping time in mice, body temperature in rats, charcoal meal propulsion in mice and urine and electrolytes excretion in rats. In anesthetized dogs, CJ-50005(0.25 and 0.75 $\mu\textrm{g}$/kg, i.v) did not alter the respiratory rate, blood pressure, heart rate, femoral blood flow and ECG. In in vitro experiment, CJ-50005 at the concentration up to 0.02 $\mu\textrm{g}$/ml did not produce any changes in the contractions of the isolated ileum of guinea pigs caused by acetylcholine, histamine or $BaCl_2$. Since these pharmacological effects of CJ-50005 were observed at dose much greater than those in clinical use (approximately 0.025 $\mu\textrm{g}$/kg, i.m.), it is likely that this vaccine may be relatively free of undesirable effects in clinical practice.

The age-specific anti-hepatitis A virus (HAV) seroprevalence rates in South Korea have changed markedly since the last 2030 years with an improvement in the socio-economic, housing, and environmental-sanitation conditions. These changes are characterized by very low anti-HAV seropositive rates among individuals less than 30 years of age; however, nowadays, most adolescents and young adults at an increased risk of developing symptomatic HAV infections. The Korea Center for Disease Control Sentinel Surveillance System has recently revealed an increase in the incidence of hepatitis A infection since 2001 and has revealed a potential endemic nature of the hepatitis A infection. Hepatitis A vaccines that were introduced in 1997 in Korea have made the current anti-HAV IgG positive rates in children (less than 10 years of age) approximately 50% of the rates observed in Seoul in 2006. However, in the same year, a few children were diagnosed as having anti-HAV IgG antibodies in Busan. This suggests the presence of some difference in the vaccination policy among doctors practicing in Seoul and Busan. Thus, the current recommendation of vaccinating 12-year-old child with HAV vaccination should be emphasized and a new strategy should be developed for the vaccination program to cater to the adolescents and young adults who are not immune, as well as for persons who are at a high risk for hepatitis A viral infection such as military personnel and hospital and day care center employees. Further, urgent hepatitis A vaccinations are also needed in patients with chronic liver diseases.

1. Objectives: This case study described a process of the patient diagnosed as acute hepatitis A treated by medication based on the Sasang Constitutional Medicine and acupuctural theraphy and obtained improved effects about several symptoms. 2. Methods: We diagnosed the male patient with acute hepatitis A as Tae-Eumin Exterior-Cold-Disease by the Cold in the Esophagus, and administered Mahwangbalpyo-tang and Handayeolso-tang according to clinical progress. And we evaluated the results by liver function test(LFT; AST, ALT, $\gamma$-GTP ), total bilirubin level and the visual analog scale(VAS) of symptoms. 3. Results and Conclusion: Almost symptoms (except for jaundice) at the time of admission were disappeared, and also jaundice (estimated by color of scleras and color of urine) was alleviated. Also level of AST, ALT, $\gamma$-GTP and total bilirubin decreased in laboratory test. We obtained positive effects to the therapy but we considered necessities of further comparative studies with control group.

Objectives: This study was conducted to examine the immunization, knowledge, and preventive health behaviors for hepatitis A in college students. Methods: Structured questionnaire survey data were collected from a convenient sample of 266 students at two universities in urban areas. Data were analyzed with Pearson correlation coefficient, t-test, ANOVA, and multiple logistic regression analysis. Results: Only 10.5 percent of the students reported having had hepatitis A vaccination. The levels of knowledge and compliance of preventive health behavior were moderate with the mean scores of 15.56(${\pm}2.12$), and 26.78(${\pm}3.41$), respectively. A significant correlation was found between knowledge and preventive health behaviors. The compliance to preventive health behaviors differed by education on hepatitis A in the past. Conclusions: Vaccination rate of hepatitis A found to be low and the knowledge and health behaviors for hepatitis A prevention among university students are limited. Provision of vaccination, education and strategies to enhance preventive health behaviors are warranted to prevent hepatitis A.

Objective: We conducted this study to report the clinical manifestations of integrative treatment with Korean and conventional medicines in a patient with acute hepatitis A after conventional medicine therapy for chronic obstructive pulmonary disease and pneumonia. Methods: A patient was treated with herbal medicine, western medicine, and moxibustion. The liver function tests (GOT, GPT, ALP, ${\gamma}-GT$), total bilirubin, and 4-scale scoring (none, mild, moderate, and severe) of symptoms were used to assess any improvement in symptoms. Results and Conclusion: The symptoms at the time of admission were improved. The levels of GOT, GPT, ALP, ${\gamma}-GT$, and total bilirubin were decreased in laboratory tests. We obtained positive effects for the integrative treatment of acute hepatitis A.

Hepatitis A is acute hepatitis caused by the hepatitis A virus (HAV), HAV is a non-enveloped 27nm, heat-, acid, and ether-resistant RNA virus in the Picornavirus family. HAV is transmitted primarily through fecal-oral route and the incidence rate of hepatitis A is closely related to environmental hygiene and socioeconomic condition. Recent improvements in sanitation, public health policies, and socioeconomic development in South Korea have had great impact on the incidence of hepatitis A, which natural production of antibodies against HAV and the prevalence of HAV antibody has decreased. However, during the past ten years, symptomatic HAV infection substantially increased among juveniles and young adults in their twenties and thirties, and hepatitis A has become one of the most common acute hepatitis. Though there has been no report on treatment of hepatitis A with jaundice by oriental medicine in South Korea, many studies and case reports on treatment of icteric hepatitis of which main symptom is jaundice have been published in other countries. To treat patients diagnosed with hepatitis or suspected cases in oriental medicine hospitals, we need to have concerned about hepatitis A. This report is disease pattern identification in oriental medicine and treatments of 3 patients who were diagnosed with acute hepatitis A and treated in oriental medicine hospital.

The acute toxicity of CJ-50005, an inactivated whole virus vaccine derived from hepatitis A virus (HM175) grown in human MRC-5 diploid fibroblast culture, was tested in Sprague Dawley (SD) rats and beagle dogs. CJ-50005 was orally and intramuscularly administered up to the maximum dose of 81$\mu\textrm{g}$/kg. as much as 3,000 times of the expected clinical dose, in SD rats and was intramuscularly administered up to 27 $\mu\textrm{g}$/kg, as much as 1,000 times of the expected clinical dose, in beagle dogs. In these experiments, there were no death and clinical changes which were related to CJ-50005 administration. In addition, there were no significant changes between control and treated groups in body weights and autopsy findings. In conclusion, the administration of CJ-50005 over 81$\mu\textrm{g}$/kg in SD rats and over 27$\mu\textrm{g}$/kg in beagle dogs was proved to be safe, and it is thought that CJ-50005 may not show any toxicity in its clinical use.

CJ-50005 is an inactivated whole virus vaccine derived from hepatitis A virus (HM175) grown in human MRC-5 diploid fibroblasts cell culture. In order to evaluate the mutagenic potential of CJ-50005, : 3 sets of mutagenicity tests were performed. In the reverse mutation test wing Salmonella typhimurium TA1535, TA1 537, TA98, TA100 and TA102, CJ-50005 did not increase the number of revertants at any concentration tested in this study (2.8, 1.4, 0.7, 0.35 and 0.175 $\mu\textrm{g}$/plate). CJ-50005, at concentration of 2.8, 1.4 and 0.7 $\mu\textrm{g}$/ml, did not increase the number of cells having structural or numerical chromosome aberration in cytogenic test using Chinese Hamster Lung cells. In mouse micronucleus test, no significant increase in the occurrence of micronucleated polychromatic erythrocytes was observed in ICR male and female mice intraperitoneally administered with CJ-50005 at the doses of 25, 12.5 and 6.25 $\mu\textrm{g}$/kg. These results indicate that CJ-50005 has no mutagenic potential in these in vitro and in vivo system.

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.
