This study used the health belief model of college students to investigate the not with regards to their health status awareness, health management, and their health beliefs. Logistic regression analysis showed a significantly high odds ratio between intent of hepatitis B vaccination and gender, The trend for receiving a hepatitis B vaccination was highest in groups with awareness of the high susceptibility and seriousness of hepatitis B, groups with awareness of the low barrier, and women as opposed to men. Therefore future research is needed regarding appropriate promotions of the seriousness and benefits of hepatitis B vaccinations as well as the development of a integrated health education mediation program and effect evaluation.

Reactivation of the hepatitis B virus (HBV) is a well-recognized complication in patients with chronic HBV infection who receive cytotoxic or other immunosuppressive therapy. In cases of patients treated by radiotherapy however, only a few of such reports exist and most of these include the patients previously treated by chemotherapy or transarterial chemoembolization. The results of this study point to a case of a patient with reactivation of HBV after radiotherapy alone. This study shows the possibility of HBV reactivation by partial hepatic irradiation alone hence, special attention should be paid to patients with HBV disease.

Radiation-induced liver disease (RILD) has been characterized as a veno-occlusive disease with anicteric elevation of alkaline phosphatase (ALP). However, some RILD patients present with elevated transaminase levels rather than with anicteric elevation of ALP, and these findings are common in the Asia-Pacific region where hepatitis B virus (HBV) infection is associated with 70~90% of hepatocelluar carcinoma (HCC) cases. In addition, the development of RILD is more common in patients with hepatitis B virus-related HCC. These findings indicate that susceptibility to RILD might be different in HBV carriers and non-carriers, and moreover, RILD in patients with HBV-related HCC might be associated with another unique pathogenesis such as HBV reactivation. However, HBV reactivation after hepatic irradiation has been reported in only a few studies. This study reports three cases of HBV reactivation alter hepatic tomotherapy for management of HCC.

The purpose of this study was to provide basic data for related researches on knowledge, attitude, and health belief related to hepatitis B and development of a preventive education program for the rise of its vaccination on college students of dental hygienics and dental laboratory technology majors. The questionnaires were distributed to a total of 252 students from April 26 to 30, 2018. The mean knowledge score of hepatitis B was 11.60 out of 20.0. The mean scores for their attitude and health belief on hepatitis B were 3.51 and 3.10 out of 4.0, respectively. Only 38.9% of the subjects were vaccinated and 53.6% of them were not educated. The factors affecting the vaccination were clinical training experience and prevention education. It is essential to provide healthcare education on knowledge, attitude, and health belief related to hepatitis B and to develop a convergent education program because the students may be manpower for healthcare institutions in the future.

Hepatitis B virus(HBV) infection is one of the major health problems in Korea and HBsAg positive rate was known to be about $5\sim15%$ in general population. This study was conducted to identify the positive rates of serum HBsAg and anti-HBs among community population regarded as having hish HBV vaccination rate than in previous decade, using EIA(Enzyme immunoassay) method, in Seo-Gu, Taegu, Korea. The study subjects were 1,160 who visited Seo-Gu Health Center for check-up serologic markers of hepatitis 3. The data were obtained from the serologic test for hepatitis markers and questionnaire survey was conducted to obtain the general characteristics, vaccination history, past history of hepatitis and other liver disease, and exposure history to risk factors of hepatitis of the study subjects. The positive rates of HBsAg and anti-HBs were 5.2% and 62.4% respectively. The positive rates of HBsAg for male and female were 6.6% and 4.3% respectively. The age was divided into two groups as group I (less than 15 years old), group II (more than 16 years old) according to the hypothesis that these two groups might be different in HBV vaccination rate. HBV vaccination rates for group I and II were 83.1% and 52.3%. The positive rates of HBsAg for group I and II were 2.6% and 6.5%. The positive rates of HBsAg for the vaccinated people of the group I and II were 2.2% and 3.5%, the positive rates of anti-HBs for the vaccinated people of the group I and II were 70.1% and 71.1% respectively. The most significant factor in positive rate of HBsAg was 'hepatitis carrier in family'. Multiple logistic regression analysis revealed that 'hepatitis history' and 'hepatitis carrier in family' were significant variables for positivity of HBsAg, and 'hepatitis B vaccination' was only a significant variable for positivity of anti-HBs.

배경: 보툴리눔 독소 A형은 강직성 질환을 비롯한 여러 질환의 치료제로 널리 사용되고 있다. 최근에 보툴리눔 독소 A형은 근육비대를 치료하기 위해 널리 이용되고 있다. 하지만 보툴리눔 독소의 근육비대의 치료효과에 대해서 알려진 바가 거의 없다. 본 연구는 토끼 정강뼈 근육에 보툴리눔 A, B형을 주입 후 시간경과에 따른 근육의 위축을 확인하여 근육비대의 치료에 보툴리눔 B형이 효과적인지 확인하고자 하였다. 방법: 36마리의 토끼를 4그룹으로 분류하였다(1 그룹: 생리식염수 주사: 2 그룹: 보툴리눔 독소 A, B - 2U, 3 그룹: 보툴리눔 독소 A, B - 5U, 4 그룹: 보툴리눔 독소 A, B - 10U). 정강뼈근육에 보툴리눔 독소 A, B형을 주입 후 1, 2, 4주에 정강뼈 근육의 부피를 측정하였다. 신경자극기를 이용하여 독소 주입 후 1, 2, 4주의 근육의 단일 수축을 확인하여 근육기능의 변화여부를 확인하였다. 결과: 보툴리눔 독소 B형을 주입시 통계적으로 유의하지 않지만 A형에 비해 근육 부피의 감소가 관찰되었다(P>0.05). 반면, 근육의 단일 수축은 보툴리눔의 용량에 관계없이 B형을 주입한 근육에서 더 높게 관찰 되었다. 결론: 보툴리눔 독소 B형을 주입한 경우 근육 기능의 회복속도는 빠른 반면 근육의 위축은 A형에 비해 더 오랫동안 지속되었다. 따라서 근육비대의 치료에 있어 보툴리눔 독소 B형이 A형보다 보다 더 효과적이라고 사료된다.

Objectives : The author wanted to summarize the psychiatric and social aspects of the patients with hepatitis B virus infection. Methods : The author reviewed all pertinent citations in the Medline database from 1966 to 1999. Results : Psychiatric problems in this population include delirium, psychotic disorder due to general medical condition(especially mania), anxiety, depression, adjustment disorder, alcohol abuse/dependence, and drug abuse/dependence. Social aspects of the patients with hepatitis B viral infection relate to the stigma of being a carrier, guilty feeling about infection, guilty feeling about increased family burden, impacts of having hepatitis on interpersonal relations, sexual difficulties, and job loss with increased financial burden, and health care worker's refusal. Conclusions : Appropriate early educational counseling interventions regarding the expected course and psychosocial intervention should be tailored to the sociocultural needs of special populations. Those interventions will increase compliance of treatment and prevent progression to hepatocellalar carcinoma from hepatitis.

This study was attempted to define epidemiologically the possibility and the magnitude of sexual transmission of HBV in Korea. Two groups of prostitutes; one group (309) deals with Koreans, the other group (126) deals with American soldiers stationing in Korea, were tested for the presence of HBsAg and anti-HBs. The prevalence rate of HBsAg or anti-HBs was significantly higher in prostitutes who deal with Koreans (41.7%) than in prostitutes who deal with American soldiers (30.2%) (p<0.025). Among the prostitutes who deal with American soldiers, there was no appreciable difference in the prevalence rate of HBsAg or anti-HBs by the duration of prostitution. However, among the prostitutes who deal with Koreans, the prevalence rate was increased with the duration of prostitution, although it did not reach the statistically significant level (p=0.12). There was no remarkable association between the prevalence rate of HBsAg or anti-HBs and educational level, history of operation or history of transfusion. The data support the possibility of sexual transmission of viral hepatitis B but it seems seems sexual transmission does not contribute significantly to the prevalence rate of HBsAg or andi-HBs in Korea.

만성 B형 간염의 경과중 흔히 볼 수 있는 간기능의 이상은 대부분 심한 황달의 동반없이 혈청 AST와 ALT의 증가만 보이면서 악화되는 것이다. 저자는 심한 황달을 동반한 16명의 만성 B형 간염 악화 환자(연구군)와 심한 황달없이 AST와 ALT치만 증가된 13명의 환자(비교군)를 비교관찰하였다. PMC 제재를 복용했던 환자는 연구군에서 11명(68.8%), 대조군에서 1명(7.7.%)으로 나타났으며 PMC를 포함하여 각종 약제 및 알콜 섭취가 저명했던 환자가 연구군에서 15명(93.8%), 대조군에서는 2명(15.4%)이었다. 혈청 HBeAg 양성율은 급성 악화전에는 연구군에서 14명 중 7명(50.0%), 비교군에서는 13명 모두 (100%)에서 양성이었으며, 급성 악화 경과후에는 연구군에서는 변함없었고 비교군에서는 13명중 3명(23.1%)에만 양성이었다. 연구군 중 anti-HBe 양성화는 한 사람도 생기지 않았고 6명이 사망하였으며 대조군에서는 8명의 환자에서 anti-HBe 양성화가 생겼고 아무도 간기능 부전으로 사망하지 않았다. 만성 B형 간질환에서 심한 황달을 동반한 급성 악화와 관련있는 요인은 진행된 만성 활동성 간염, 간경변 등 근본적으로 진행된 간기능 저하와 동반된 부적절한 약제나 알콜 복용이 확실히 관계있을 것으로 사료되며 간기능 부전도 그리 드물지 않다. 반면에 간경변으로 진행되기 전 상대적으로 진행이 덜 된 비교군의 만성 B형 간염 환자에서는 황달의 저명한 증가없이 간기능이 갑자기 악화될 때는 자연적인 혈청 anti-HBe 양성전환의 동반이 흔한 것으로 나타났다.
