The purpose of this study was to identify the effect of structured patient education on knowledge of Hepatitis B type and behavior about self care in chronic hepatitis B patients, and to fine the strategy to promote their self care behavior. The research design was quasi-experiment research. The study method had been done by investigating the experimental group and control group through the questionnaire on 50 patients who had been out patient medicine department in U university hospital in Ulsan from september 1st 1997 to the end of October, 1997. The analysis of the collected material had been done for the homogeneity test in which general characterics of experimental group and control group had been tested by $x^2-test$ and the homogeneity test of the knowledge of hepatitis B type and self care behavior before by t-test. To test the hypothesis the t-test had been given for the difference of the knowledge of hepatitis B type and self care behavior between the two groups and the correlation between knowledge of hepatitis B type and self care behavior performance had been tested by Pearson's correlation coefficient. The results as follows : 1. The 1st hypothesis 'The experimental group which received the structured education should be higher in the knowledge of hepatitis B type than the control group' was supported(t=-6.25, P=.000). 2. The 2nd hypothesis 'The experimental group which received the structured education whould be higher in the self care behavior performance than the control group' was supported(t=-5.15, P=.000). 3. The 3rd hypothesis 'The higher the knowledge of hepatitis B type in the patient the higher the self care behavior performance degree' was supported(r=.492, P=.001). In conclusion, the patients who received the structured education showed the increase in the degree of knowledge of hepatitis B type and self care behavior performance. so the structured education had been judged the nursing intervention had been prerequisite in increasing knowledge of hepatitis B type and self care behavior performance of the chronic hepatitis B patients.

Background: To assess the effect of an information leaflet on the level of Chinese youth's knowledge about hepatitis B and hepatocellular carcinoma (HCC), the most common type of primary liver cancer (PLC). Materials and Methods: A total of 500 students, from two universities in the Chaoshan area of China, were randomly divided into an intervention group of 280 participants and a control group of 220. Baseline knowledge of HCC and hepatitis B was evaluated by questionnaire interview. Subsequently, only the intervention group was given an information leaflet of HCC and hepatitis B. Three months later, the two groups were contacted for a second interview. Changes in knowledge from baseline of HCC and hepatitis B were compared between the two groups. Results: There was no statistically significant difference in mean PRE-questionnaire scores between the intervention and control groups. However, the mean POST-questionnaire score was significantly higher in the intervention group after the intervention. The leaflet had the greatest effect on the participants' questionnaire score, and raised their level of knowledge about HCC and hepatitis B. Conclusions: The information leaflet intervention is significantly effective in improving the knowledge of HCC and hepatitis B among the youth.

Purpose: This study was conducted to develop educational materials for preventing type B viral hepatitis infection. Prior to this study, a survey had been conducted to define the educational needs of persons with hepatitis B antigen. Method: Based on the results of the former study and a review of the literature, the content of the educational materials was confined to the transmission cycle and its prevention in type B hepatitis. A professional team that consisted of writers and producers videotaped the lectures provided by professors and instructors in a nursing school. A professional graphic designer produced the leaflet to enhance the visual effects. Results: The contents of the educational materials for type B hepatitis were composed of six parts: (1) the prevalence rate (or morbidity) of type B hepatitis antigen positive and its recent trend, (2) transformation of hepatitis. (3) transmission cycle of hepatitis infection, (4) persons who are susceptible to hepatitis and need a vaccination, (5) preventive approach hepatitis vaccination and the guideline for patients' daily lives for preventing infection and (6) questions and answers. The materials were delivered in the form of lectures, visual charts, graphics, and multi-media. Conclusion: The educational materials developed in this study may provide practical information and knowledge on strategies to prevent type B hepatitis. The educational materials may be utilized in primary health care centers or school health services.

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.

This study was carried out to find the influencing factors on the acceptance of vaccination of viral hepatitis type B. Two groups of students, 362 undergraduates of Korea University were surveyed for research. The compliant group was 156 students who were inoculated with viral hepatitis type B shot more than one time. The non-compliant group was 206 students who were not inoculated. The measures used for this study were Multidimensional Health Locus of Control Scales and the one developed by the researcher on the basis of literature review about Health Belief Model. The results of this stuby were as follows. The awareness on health of the compliant group was higher than that of the non-compliant group(t=0.39, P<0.05), And perceived barrier of the compliant group was lower than that of the non-compliant group(t=0.35, P<0.05). But the knowledge about the viral hepatitis type B of the compliant group was lower than that of the non-compliant group(t=2.49, P<0.05). There were no differences between two groups in the perceived susceptibility of the hepatitis and the perceived benifit of the hepatitis vaccination. There was no difference between two groups in terms of the Inner Health Locus of Control (HLOC) and Chance HLOC. On the other hand Powerful-Others HLOC of the compliant group was higher than that of the non-compliant group(t=3.67, P<0.05). 'Parent's advice' was found to be the major answer to the motive of being vaccinated in the compliant group. This explains that the most influencial factor in determining one's health behavior is the parent's opinion. Answers to the question of the reason of not being vaccinated were, 'did not want to bother' and 'did not care yet' in order. As a whole, except for the awareness on health and the perceived barrier of the hepatitis vaccination, this study result shows disagreement with the past investigations on the inter-relationship between one's health belief or Health Locus of Control and the health behavior. The author of this study believes this was due to the limitation in the survey group's particular homogenity.

The hepatitis B virus(HBV) is a small, enveloped virus with a circular, double-stranded DNA genome. HBV causes active and chronic hepatitis worldwide, including Korea, and is considered to be a major factor for liver cirrhosis and hepatocellular carcinoma. In contrast to the wealth of knowledge on the gene structure and expressional regulation, immunological and pathological mechanisms for HBV-induced hepatocellular injury are not well known. In the present study, vaccinia virus which has been demonstrated to be a useful eukaryotic expression vector was used to clone the gene for HBV surface antigen, L(S+preS2+preS1). The recombinant vaccinia virus vector, pMJ-L, which contains L surface antigen gene of adr-type HBV was constructed, and subseouently used for making recombinant vaccinia virus VV-$\textrm{HBV}_{L}$. Expression of the HBV antigen was examined by immunofluorescent antibody (IFA) test using mouse monoclonal anti-hepatitis B surface antigen. HBsAg was detected in the recombinant virus indicating that the VV-$\textrm{HBV}_{L}$ expressed S antigen successfully. The HBV-Vaccinia Virus recombinant obtained in this study is currently being used for studying the immunological aspects of HBV infection.

Viral oncology is focused on understanding the relationship between cancer and viruses, which are known to play a role in the development of certain types of cancer. Approximately 15-20% of human cancers are believed to be caused by oncogenic viruses, and as a result, there is significant interest in understanding how these viruses contribute to cancer development. There are several viruses that have been linked to cancer, including human papillomavirus, hepatitis B and C virus, Epstein-Barr virus, human T-cell lymphotropic virus type 1, Kaposi's sarcoma-associated herpesvirus, and Merkel cell polyomavirus. Each of these viruses is associated with different types of cancer, and the mechanisms by which they contribute to cancer development are diverse. This article discusses these mechanisms as well as current and future strategies for preventing and treating virus-associated cancers with the goal of presenting a thorough review of the current state of knowledge in viral oncology and to highlight the importance of continued research in this field.

Vaccines are products for immunization which can provoke antibodies by eliciting immune reponses without causing disease and have played an important role in preventing fatal and contagious diseases as well as H1N1 influenza. They are classified by two following categories; lived attenuated vaccine and killed vaccine and currently commonly using vaccines are BCG, diphtheria, tetanus, mumps, measles, rubella, polio, Haemophilus influenza type b, hepatitis B, influenza etc. All vaccines must be used correctly to reach optimal therapeutic goals and also informed well to patients to decrease potential problems. In order to do, pharmacists must have good knowledge of vaccines. The purpose of this study is to evaluate the necessity of vaccine education for pharmacists and develop a vaccine leaflet for patient counseling. We have performed a survey with questionnaire for a total of 176 pharmacists and nurses(hospital pharmacists, n=65; community pharmacists, n=50; hospital nurses, n=61) from January 27th to March 12th, 2010. The questionnaire includes items about vaccine education and counseling and 12 quizzes to evaluate responders' knowledge of vaccines. We used the SPSS(Version 12. for windows) program to analyze the data. In results, 94.9% of all responders said they had not been educated on vaccines. And only 1.1% of all responders said they know about vaccines enough to counsel patients. Pharmacists who have an experience recommending vaccines to other people are 21.7%. On the other hand, nurses who have an experience recommending vaccines to other people are 55.7%(p=0.000). The mean number of correct answers at the 12 quizzes are followings; hospital pharmacist, 8.1; community pharmacist, 6.1, hospital nurses, 6.2(p=0.000). A vaccine leaflet for patient counseling is developed with several references. In conclusion, due to no opportunity of vaccine education, pharmacists have no confidence to counsel patients and lack of knowledge of vaccine. But importance of vaccine's role is increasing, pharmacists should counsel patients in vaccination. So they need vaccine education and a vaccine leaflet will be helpful for their counseling.

Since the first report of RNA interference (RNAi) less than a decade ago, this type of molecular intervention has been introduced to repress gene expression in vitro and also for in vivo studies in mammals. Understanding the mechanisms of action of synthetic small interfering RNAs (siRNAs) underlies use as therapeutic agents in the areas of cancer and viral infection. Recent studies have also promoted different theories about cell-specific targeting of siRNAs. Design and delivery strategies for successful treatment of human diseases are becomingmore established and relationships between miRNA and RNAi pathways have been revealed as virus-host cell interactions. Although both are well conserved in plants, invertebrates and mammals, there is also variabilityand a more complete understanding of differences will be needed for optimal application. RNA interference (RNAi) is rapid, cheap and selective in complex biological systems and has created new insight sin fields of cancer research, genetic disorders, virology and drug design. Our knowledge about the role of miRNAs and siRNAs pathways in virus-host cell interactions in virus infected cells is incomplete. There are different viral diseases but few antiviral drugs are available. For example, acyclovir for herpes viruses, alpha-interferon for hepatitis C and B viruses and anti-retroviral for HIV are accessible. Also cancer is obviously an important target for siRNA-based therapies, but the main problem in cancer therapy is targeting metastatic cells which spread from the original tumor. There are also other possible reservations and problems that might delay or even hinder siRNA-based therapies for the treatment of certain conditions; however, this remains the most promising approach for a wide range of diseases. Clearly, more studies must be done to allow efficient delivery and better understanding of unwanted side effects of siRNA-based therapies. In this review miRNA and RNAi biology, experimental design, anti-viral and anti-cancer effects are discussed.
