BACKGROUND: Administration of hepatitis B vaccine has played a major part in the management of public health in this country. There were many researches to assess the immunogenecity, safety, long term effectiveness, dose, and route of administration of hepatitis B vaccine. But there was lack of validation of the recommendation that hepatit.is B vaccine should be administered in adults with negative HBsAg and AntiHBs, in an endemic area with high prevalence of HBsAg. Authors tried to establish a proper candidate for hepatitis B vaccination evaluating viral markers of hepatitis B in adults vaccinated. METHODS: 172 hepatitis B vaccinated subjects(35.0%) were drawn from 491 adults who have visited at health care center, Asan Kangnung Hospital from April 1st to May 31th, 1997. They were asked designed questions about the beginning year, frequency of vaccination, and the presence of family members with HBsAg in a direct line. RESULTS: Of the subjects(172), 2.3% were HBsAg(+), 63.4% AntiHBs(+), 68.6% AntiHBc(+). Among the HBsAg(-) adults(149) who had been vaccinated more than three times, 70.4%(105) were AntiHBs(+), of whom 66.6%(70) were AntiHBc(+) and 29.6%(44) were AntiHBs(-), of whom 56.8%(25) were AntiHBc(+). In the subjects(20) with family history of HBsAg, 80% were AntiHBc(+), which is higher than 61.2% in the group(129) without family history. Among the HBsAg(-) and AntiHBc(-) adults(54) who had been vaccinated more than three times, AntiHBs(+) group was not significantly differnt from AntiHBs(-) group in comparison of age and years after initial vaccination. CONCLUSIONS: The two thirds(68.9%) of vaccinated subjects showed AntiHBc(+), which means reflection of previous exposure to Hepatitis B virus. Accordingly, vaccination is not thought to be required for these. Consequently, all individuals are thought to have to be pretested for the presence of AntiHBc as well as HBsAg and AntiHBs in Korea.

BACKGROUND: In a health examination program, advice from physician for change of health-related behavior and distribution of health educational pamphlets is routine. This study was done prospectively to analyze factors such as personal general characteristics, results of health examination, health examination satisfaction that relate to change of health promotion attitudes and compliance towards overweight, smoking, heavy drinking, elevated blood pressure, dyslipidemia, chronic diseases such as diabetes, hypertension. METHODS: The subject population was 689 cases from May 1997 to June 1997 in a general hospital health examination center. After health examination, 60.2%(415 cases) showed personal satisfaction by questionnaire. Three to four months later 78.4%(540 cases) responded to the telephone survey on change of health beliefs, health-related attitudes and compliance. RESULTS: In the telephone survey, 239 cases(46.0%) comprised high compliance group that had positive attitudes toward abnormal health examination results, 145 cases(27.9%) were mid compliance group, and 135cases(26.0%) were low compliance group. In males there was higher frequency of high compliance group than females(p<0.05). According to age, the older, the higher frequencies of high compliance group(p<0.05). In educational level group, the higher the educational level, the lower the frequencies of high compliance group(p<0.01). There was no difference in frequency of each compliance group between symptom motive and non-symptom motive group with each satisfaction group(p>0.05). In positive responders to the correspond advice of physician or health educational pamphlets, the frequencies for quit smoking, reduction of drinking amount, regular exercise, Compliance with taking antihypertensives, blood sugar control, diet control for dyslipidemia, taking antihyperlipidemics were higher(p<0.01). CONCLUSIONS: Health examination service includirg advice of physician and education changed health belief and influenced positively to health promotion attitudes. Health examination is not only important for early detection of disease but also to promote positive change of health-related behavior. Further studies are needed to understand the changing process of management of health and disease.

BACKGROUND: In korea, Improvements of standards of hygiene, sanitation and water supply led to a significant reduction in the endemicity of HAV infection, so that hepatitis A outbreaks have shifted from children to adolescents and young adults. Hepatitis A infection becomes more symptomatic with increasing age. We studied Hepatitis A antibody prevalence in college students, who start living a active life in a community. Hepatitis A infection is primarily by the fecal oral route transmitted disease by either person to person contact or ingestion of contaminated food or water. So, We studied follow up prevalance of anti HAV IgG in college students who were living together in dormitory during 1 year. METHODS: The 668 serum samples were obtained from college students living in dormitory, Kangung National University during the period of May 2nd through 5th, 1999. For follow up study, the 158 serum samples were obtained from this group during the period of May, 2000. Anti HAV IgG was measured by HAVAB radioimmunoassy. RESULTS: The overall seroprevalence rate of anti HAV IgG was 16.3% in 1999. According to age, the anti HAV IgG positive rate was increase with age, 10.5% in 18 years, 12.4% in 19 years, 15.9% in 20 years, 22.5% in 21 years, 27.9% in 22 26 years. The seroprevalence of anti HAV IgG was increase with year of university entrance, but not different with sex, department of college and number of family. The anti HAV IgG positive rate in urban group(14.7%) of native place was lower than in rural group(21.5%). Seroconversion rate of negative anti HAV IgG was only 1.3% during I year. CONCLUSION: This study showed that the seroprevalence of hepatitis A virus was a dramtic drop among adolescent and young adulthood in korea. Natural acquisition of HAV antibody rarely occurs during 1 year in living condition such as dormitory.

Adenosis tumor is a ra re tumor of the breast and primarily consists of adenosis. Authors report a case of surgically proved adenosis tumor in a 31-year-old woman. Mammogram showed a Iobulated, well-circumscribed mass with several surrounding radiolucent halos. In the center of the mass several linear radiolucent densities were seen with the appearance of a conglomerated well-circumscribed mass such as fibroadenoma. These linear radiolucent densities were consistent with the fat between the fibrous sclerosis in pathologic specimen. Ultrasonogram showed a well-circumscribed mass with homogeneous low echogenicity, partial posterior enhancement, and bilateral acoustic shadowings.

Several studies have reported that heavy metals have a relation with osteoporosis and osteoporotic fractures. In this study, we investigated the association between heavy metal exposure status, as assessed by serum major heavy metals such as lead (Pb), cadmium (Cd), and mercury (Hg) and bone mineral density (BMD) status among Korean adults. A total of 64 adults participated in this study and were assigned to one of three study groups based on the T-score of spine BMD: a normal group (n = 21, T-score > -1), osteopenia group (n = 29, -2.5 < T-score < or = -1) and osteoporosis group (n = 14, T-score < or = -2.5). We also assessed serum levels of heavy metals (Pb, Cd and Hg) by using atomic absorption spectrometer (AAS) and daily nutrient and food intakes for 3 days by using 24-hr recall method in the subjects. The mean age was significantly higher in the osteoporosis group compared with the osteopenia and normal groups (p < 0.001). There was no significant difference in serum levels of Pb, Cd and Hg among the three groups after adjusting for age. Daily intakes of energy, nutrients were not significantly different among the three groups. The osteoporosis group consumed significantly higher fish and shellfish than the other groups (p < 0.05). In the correlation analysis controlling for age, sex, BMI, and BMD status, the serum Cd level was significantly negatively correlated with intake of cereals, milks and total food. In summary, we did not find a direct association between serum heavy metal levels and BMD status. However, negative relationships were found between serum heavy metal levels and intake of some foods.

BACKGROUND: Hepatitis B is a leading cause of chronic hepatitis, cirrhosis, and hepatocelluar carcinoma. It is a well-known fact that Korea is one of the hyperenedemic areas of Hepatitis B virus among East Asian countries. Many pnst reports have shown that positive rate of HBsAg in Korea was about 6-14%. But precise data for Yongdong area of Kwangwon Province in Korea was lacking. Here authors report on the prevalence of viral markers of hepatitis B among adults in this area. method: Sera were collected from 7469 residents in Yongdong area of Kwangwon Province who visited the Health Care Center, Asan Kangnung Hospital from September 11th to August 31th. HBsAg, AntiHBc-IgG, and AntiHBs were tested by radioimmunoassay. RESULTS: Positive rate of HBsAg of total study subjects was 8.5%, and was significantly decreased as age increased, and higher in males(10.2%) than in females(6.6%). Positive rate for one or more markers among HBsAg, AntiHBc-IgG, and AntiHBs was 84%, and was significantly increased as age increased, and higher in males(86.2%) than in females(81.2%). All negative rate for HBsAg, AntiHBc-IgG, and AntiHBs was 16.0% and all positive rate was 0.5%. Positive rate of AntiHBc-IgG without HBsAg and AntiHBs was 15.7% Positive rate of AntiHBs without HBsAg and AntiHBc-IgG was 11.7%. Positive rate of AntiHBc-IgG and AntiHBs was 72.1% and 60.2%, respectively. CONCLUSIONS: There was no significant difference in positive rate of HBsAg between this study for residents in Yongdong area of Kwangwon Province and past many reports. 84% of the total study subjects showed serological evidence of previous exposure to hepatitis B virus (HBV) naturally exposed or by vaccine immunization. 16% of the total study subjects was a proper candidate for hepatitis B vaccination.

PURPOSE: Tumor growth in a given neoplasm is the net result of cell proliferation and cell loss, and apoptosis is the most significant component of continuous cell loss in most tumors. In this study, we examined non-Hodgkin's lymphoma (NHL, n=67) immunohistochemically for the presence of Bcl-2 oncoprotein and P53 protein and compared apoptotic indices (AIs) and Ki-67 proliferative indices (percentages of Ki-67 positive cells). MATERIALS AND METHODS: 67 patients with NHL were evaluated : 3 low-grade and 64 intermediate-grade. The phenotype was determined in 65 cases : 47 (70%) were B cell type and 18 (27%) were T cell type. AIs and Ki-67 proliferative indices were determined immunohistochemically and the overexpression of P53 and Bcl-2 protein were also evalutated. RESULTS: The overexpressions of Bcl-2 protein and P53 protein were found in 40% (26/65) and 31% (20/ 65). The AI ranged from 0% to 15% (mean 2.16, median 1.2). Cellular Bcl-2, which counteracts apoptosis, was significantly ( p=0.005) associated with AIs. Ki-67 proliferative indices ranged from 1% to 91% (mean 55.4), and P53 was significantly ( p=0.000) associated with Ki-67 proliferative indices. A positive correlation between AIs and Ki-67 proliferative indices was revealed ( p=0.012) in Bcl-2 positive patients. CONCLUSION: In NHL, we observed a correlation between AIs and Bcl-2 expression, between Ki-67 proliferative indices and P53 expression, and between AIs and Ki-67 proliferative indices in Bcl-2 positive patients. Our results suggest that cell apoptosis may be inseparable from cell proliferation during tumor growth.
