A case-control study was conducted to investigate the effect of low-level blood lead on the blood pressure. The plasma renin activity (PRA) was measured also to investigate one of the possible mechanisms by which lead may play a role to influence on the blood pressure. Seventy-two hypertensive and sixty-nine control study subjects were selected from the workers who had no history of job-related lead exposure, in Ulsan city and it's vicinity, Korea. In addition to measuring blood lead levels and PRA, body mass index(BMI), hematocrit, serum sodium, potassium, creatinine, ionized calcium, and cholesterol were measured. Also, the habits of smoking, alcohol drinking and family history of hypertension were checked. The blood lead level of the hypertensive group was 19.8+/-5.5 microgram/dl, which was significantly higher than that of the control group, 12.5+/-4.7 microgram/dl (p<0.01). On multiple logistic regression analysis, the odds ratio of blood lead level on the occurrence of high blood pressure was 1.38, also statistically significant (p<0.01). There was no significant differences between the hypertensive and the control group in the PRA or In(PRA), but there was a marginally significant linear relationship between blood lead and PRA in the hypertensive group (p<0.1). In conclusion, blood lead level which has been known to be within normal limits may be one of the possible risk factors of hypertension and PRA alteration by lead may act as one of the mechanisms.

A review has been made of mortality trends in Korea from 1958 to 1907 analyzing the data by sex, age and cause of death. The crude death rates and age specific death rates were estimate6 by the model of N. Keyfitz life table which had teen developed by the data of the 1960's national census. The cause specific death rates shown in this article are based on the following: all deaths occurring in the death-registration are expressed as a numberator, while the denominator was estimated from the regular national census data by interpolation method. It is estimated that only an average of about 40% of deaths which occurred during a year were registered during 1958 to 1967. The validity and the reliability of the diagnosis of causes of death seem to be extremely poor in this country. Therefore the cause specific death rates in this article are aimed to reveal trends of causes of registered death and not for the actual level of death rates. For 10 years very interesting mortality trends were observed : 1. The trend in the crude death rates was downward slowly. 2. The estimated death rate for the infant in 1960 was still high up to 100 per 1,000. 3. The rates for mortality attributed to such infectious diseases as pneumonia, bronchitis, gastroenteritis and measles decreased an average 40-60%. 4. The death rates for over-all tuberculosis decreased only 9.8%. 50% of the decrease was contributed by those in the less-than-15 year age group. 5. The death rates for chronic diseases, such as vascular diseases affecting the central nervous system, malignant neoplasm, major heart diseases and all accidents rose about 40-60%. 6. The rank order of the 10 leading causes of death showed large changes over the years, except for pneumonia and tuberculosis which occupyed 1st and End places respectively. Vascular diseases affecting the central nervous system moved from 5th to 3rd place and malignant neoplasm from 6th to 4th palace. The major heart diseases moved from 10th to 6th place and all accidents from 10th to 7th place. On the other hand, gastroenteritis moved from 3rd to 5th place and influenza from 4th to 8th place.

This report is a part of the health survey, which was carried out in the summer of 1973 on all adults older than 15 years of age, inhabiting in the sampled area. Thirteen villages out of 31 natural villages in Shindong Myon, Chunseong Gun, Kangwon Province, a typical rural area of Korea were randomly sampled. A little over 70 percent of the population sampled, or 1198 persons were examined. The health survey included laboratory screening tests, history taking, physical examination and consultation to specialists for selected cases. Diseases of circulatory system were classified by WHO ICD A-List (150). Hypertensive heart disease was defined by the criteria that was used in U.S. Health Survey, and hypertension by WHO criteria for the purpose of comparison. Results obtained were as followings: 1. The overall prevalence of the diseases of circulatory system per 100 adults examined was 8.6 for male and 9.9 for female. 2. Age specific prevalence of the diseases showed gradually increasing pattern as age advanced for both sexes. For example, the prevalence for 15~19 years old age group was 2.4/100 adults which increased to 24.8 when age reached over 60 years. 3. The most prevalent disease category, 3.6/100 adults, was A-88: other diseases of circulatory system that was consisted mainly of varicose vein and hemorrhoids; the second one was hypetensive heart disease, 2.4. 4. Female had higher prevalence than male in A-84: other form of heart diseases (4 times, arrhythmia, beriberi heart disease, and heart disease secondary to anemia), in chronic rheumatic heart disease (4.5 times), and in hypertensive heart disease (1.4 times); in other hand, cerebrovascular diseases (4.5 times) and diseases of arterioles and capillaries (1.5 times) occurred more frequently among males than females. 5. The proportion of hypertensive heart disease among persons with definite hypertension was 22.0% for male, 25.8% for female, and it increased gradually as age increased. Hypertensive heart disease among persons with borderline hypertension was 2.2%. Only 27% of hypertensive heart disease patients had previous treatment for hypertension. 6. The prevalence of definite hypertension per 100 adults examined (double blood pressure check with interval of 30~40 minutes) was 9.5 for male, 9.4 for female, with increasing pattern by advancing ages; marked increase occurred after age of 45 years for male and 35 years for female. The prevalence of hypertension in this study was much lower than that of the study on employees of Korea Electricity Comparny when compared with the same age groups. 7. Electrocardiographic findings on 105 heart disease suspects revealed left ventricular hyperspecific change in 4 persons. This study was supported by China Medical Board of New York Inc.

This study was carried out to investigate for resistance of V. parahaemolyticus that isolated from patients of food poisoning and fish and shellfish, captured in east coast of Kyungpook province of Korea from 1985 to 1986. VP ATCC 17802 and NAG V. ATCC 6538 were used as control. In fish, shellfish and seaweed, the more temperature increased, the shorter survival time was. In case of sea-water, the more temperature rose up, the longer survival time was, particularly in 37 degrees C and 25 degrees C, the strains had survived after 6 months. And in tapwater, it was sterilized in 150 mins. and survived for 11.5 days on maximum in ground water. In kimchi, at room temperature, germicidal time was shorter more than 6 times compared with that which had been kept in refrigerator. It survived for 57.1 days in milk, 49.2 mins. in yougurt. Strains had been surviving in frozen condition at -70 degrees C even after 6 months, present study time. In resistance test in water bath at several degrees of temperature, all the strains were sterilized in 20 mins. with 60 degrees C. In resistance test to driness, number of surviving strains dropped rapidly in 10-11% water contents. In UV 2538A, strains were sterilized in 20 mins. In resistance test to alcohol, strains had survived for 0.1-4 mins. in fermentative wine of below than 25% and distilled wine of over than 25% in alcohol concentration. The bactericidal concentration of disinfectant was 1% in phenol and 3% in cresol. In 0.1M acetic acid and 0.1M lactic acid, number of surviving colonies decreased rapidly but not in citric acid. The more NaCl concentration rose up, the lower decreasing rate of number of surviving colonies was. The strains had showed sensitive response to vancomycin, chloramphenicol, gentamicin, and resisted to carbenicillin, ampicillin and kanamycin. When one day culture strain was cultured till 25th day, resistant strains to tetracycline and cephalothin were changed to sensitive.
