BACKGROUND: A survey is the only direct way of determining the distribution of behavioral risk factors among a population. The department of Family Medicine in Seoul national university hospital adopted telephone interviewing for collecting information about behavioral risk factors of Koreans. Because methodological aspect of telephone survey is different according to the telephone and communication environment of the area in which the survey would be held, we tried to figure out adequate methodological aspects of a telephone survey on the behavioral r isk factor in Korea. METHODS: We sampled telephone numbers from the telephone number database which is supported by Infornet Ltd. with stratified cluster random sampling method and selected respondent by using algorithm of Kish. 13 part-time job interviewers were trained for 6 hours and then interviews were made in a fixed area for the time assigned. RESULTS: 13 interviewers tried to do 1,826 interviews for 4 weeks. Sociodemographic characteristics of respondents were compared with the census estimates and another face to face interview and there were no significant differences. A response rate of 79.8%, refusal rate of 12.9% and interview efficiency of 58.1% were obtained, yielding 1060 completed interview. A total of 28,830 person minutes of interview time were spent on the survey with an average of 27.2 minutes per completed interview. CONCLUSIONS: Sampling method using the telephone number database could be used keeping the representativeness of the samples and telephone survey was considered to be reliable and affordable method for determining the prevalence of behavioral risk factors in Korea.

25 males, aged 40-60 years, who participated in aerobic-type exercise on moderate intensity(60~85% of MHR), 3~5 days a week for 6~12 months were selected. Data were obtained at pre- and post-participation of tranining period for height, weight, girths of chest and abdomen, body fat, BP, HR, serum cholesterol, triglyceride, HDL-cholesterol, glucose, uric acid, BP and HR during graded treadmil exercise, and VO2max. After training for average 38.4 weeks, significant reductions occured in percent of body fat, HR and SBP both at rest and exercise, triglyceride, but not in cholesterol, LDL-cholesterol. And DBP, HDL-cholesterol were elevated. VO2max was increased apparantly by 16.4%. From the results was concluded that training of aerobic exercise could reduce the risk of coronary heart disease by 1) decreasing myocaridal oxygen demand, 2) improving on lipid profile, 3) increasing cardiac work capacity.

Korean Ginseng (Panax C.A. Meyer) has survived empirical efficacy as tonic and geriatric agents for several thousands of years in oriental herbal medicine. But there has been numerous controversial reports about its use in aged hypertensive men due to its allegedly hypertensive effects. Therefore, the author conducted the pharmacological studies of Korean Ginseng extracts on the blood pressure and blood lipid metabolism, during development of hypertension, using SHR(Spontaneously Hypertensive Rat), counterpart model of human essential hypertension. The results obtained were as follows: 1. SHR could be grouped, according to their age, as prehypertensive stage(<6th week after birth), labile hypertensive stage(6th 14th week), early established hypertensive stage(14th-20th week), and late established hypertensive stage(>20th week). 2. Plasma renin activity tended to rise steadily, until established hypertensive stage was reached. Thereafter, plasma renin activity tended to decline. 3. The changes of blood pressure due to Ginseng extract, depended on the amount, route and duration of its administration. Low dose of Ginseng tended to increase blood pressure but high dose of Ginseng tended to decrease blood pressure, until 1 week of intraperitonal administration. But prolonged administration of Ginseng extract beyond 1 week, showed delayed hypertensive effect in the intraperitoneal administration but not in oral administration. 4. SHR seemed to have abnormalities in the lipid metabolism. SHR showed lowered level of serum cholesterol and phospholipid, whereas slightly higher level of triglyceride, and showed lower alpha-lipoprotin fraction but higher pre beta-lipoprotein fraction, as compared with NCR.(=Normal Control Rat). 5. When high fat cholesterol salt diet was fed on, it was possible to indece hyperlidemia and increment of hypertension in SHR. but when high fat cholesterol salt diet and Ginseng extract were fed on concomitantly, Ginseng showed significant inhibiting effect on the development of hyperlidemia and hypertension.

BACKGROUND: Korea is, known to be an endemic area of viral hepatitis B, and 5-6% of population are carriers. Immunization can reduce the spread of hepatitis B infection. Hower, not all people respond to hepatitis B immunsation. 5-15% of primary vaccinees fail to be immunized. After revaccination, only 37.5 44% of the primary failures elicit antibody response. Recent studies have reported that it is effective to inject a double dose vaccination in immunocompromsed patients. In some country, they recommend that neonate whode mother is HBV carrier shoud receive double dose vaccination. This study documented the results of double dose vaccintion only once to nonrsponders toward the HBV immunzation. METHODS: Healthy nonresponders to Hepatitis B immunization were recuited from Sep. 1995 to Aug. 1996. Subjects with their AST/ALT level over 40, or over 65 years old were excluded. They were received 2ml of plasma-derived vaccine(Hepavax-B) intramuscularly in the deltoid muscle. Anti-HBs antibody testing were performed at 1 to 3 months after vaccintion. RESULTS: 17 healthy nanreponders to Hepatitis B immunization(male 10, female 7) were included. Their mean ages were 47(32 to64), AST/ALT level 20/19(16 to 28/11 to 35), smoking 4.3pys(1 to 7). Seroconversion occured in 13 of them(76.5%). CONCLUSIONS: Nonresponders to Hepatitis B vaccintion respond well to double dose vaccination once.

Many physical and psychological problems, involved in shiftwork were noted, including peptic ulcer, rheumatoid arthritis, sleep disturbances, anxiety, etc. But emotional and psychological problems in nighttime workers were not sufficientiy investigated. To evaluate psychological problems encountered by night duty workers, Symptom Checklist-90-Revision was administered to 61 workers, including 47 night duty workers and 14 ordinary daytime workers, and the results of the both groups were compared. 1. Of 9 symptom dimensions, depression and hostility showed significantly higher scores in night duty workers. 2. Three global indicies(GSI, PST, PSDI) of night duty workers were higher than those of daytime workers, but statistically not significant. 3. Scores in all symptom dimensions, except somatization and hostilithy, of investigation group were lower than those of norm group. 4. In night duty workers, duration of night-time work per day was positively correlated with depression, anxiety, phobic anxiety and psychoticism. From the above results, it was suggested that psychological health maintenance program should be developed for night duty workers.

BACKGROUND: The patients visiting the primary care complain of the various symptoms. This symptoms may induce the stress or the reverse. In fact the stress can influence the symptoms and signs. So this study was done for the correlation of the symptoms and signs with stress. METHODS: This study was done about the patients visiting the family medicine department of the one university hospital. We collected the all items that can find in the charts for examining the symptoms and signs, and did the requests pater the patients wrote by themselves. The stress test was Psychosocial well being index to be constructed from the General Health Questionnaire. We tested the study by t-test, anova, chi-square, linear logistic regression. RESULTS: The total study numbers were 351. The stress cut-off point was 63 score. The stress group was consisted of 15 males and 43 females. The meaningful symptoms were headache, dizziness, fatigue, weakness, insomnia, anxiety or depression. The meaningful diagnoses were anxiety or depression, tension headache(p<0.05). The meaningful sociodemographic factors were female, housewife or unemployed, menopause, monthly income below 200 ten thousands won. CONCLUSIONS: It was found that the some symptoms and signs were statistically correlated with stress.

Two cases of acute digitalis poisoning were presented. The first patient was 20-year-old male with asymptomatic ventricular septal defect (maladie de Roger) who attempted suicide by ingestion of degitalis leaf about 6.0 g (60 tablets). He developed severe epigastric pain and vomiting one hour after ingestion. Syncopal attack was developed once for a few minutes and recovered. Electrocardiogram revealed 2:1 A-V block. By conservative management he was recovered. The second patient was 2-year-old, healthy baby who ingested digoxin about 2.5 mg(10 tablets) by accident. He developed severe vomiting and electrocardiogram revealed 1degrees, 2degreesand 3degrees A-V block in series. He was recovered by conservative management without sequele.
