  • Objectives: This study was conducted to evaluate a relationship between the blood concentrations of toxic metals and the blood pressure in people living near the copper smelter. Methods: The study included 570 adults living within 4km of the smelter. We compared systolic and diastolic blood pressure between tertiary groups for blood cadmium, mercury and lead levels, respectively. Multiple regression analysis was performed to identify risk factors affecting systolic and diastolic blood pressures. Results: In male subjects, there is a significant difference in the mean of systolic and diastolic blood pressure between tertiary groups of blood cadmium and mercury levels, but in women, there was no significant difference in the mean systolic and diastolic blood pressures in all tertiary groups of heavy metals. The results of multiple regression analysis showed that age, BMI, and cadmium concentration in men were risk factors for blood pressure. In women, age and BMI, drinking and smoking, and blood mercury were significantly influenced to blood pressure. Conclusions: Residents living near the Janghang smelter showed high concentrations of blood lead and cadmium, suggesting that they were exposed to high concentrations of heavy metals released from the smelter in the past. Such exposure may have caused some blood pressure increase. Especially, the concentration of cadmium in the case of men and the concentration of mercury in blood in the case of women were found to be significantly related to the increase of blood pressure. The local population should be advised to make efforts to reduce exposure to environmental contaminants, in order to minimize cardiovascular disease, and to pay close attention to any health problems possibly related to toxic metal exposure.

  • Valy-Tyrosine (VY) derived from alkaline pretense hydrolyzate of sardine muscles showed the in vitro Angiotensin I converting enzyme (ACE) inhibitory activity and the in vivo antihypertensive effect in SHR. We investigated the antihypertensive effect of the VY on mild hypertensive subjects including subjects with high-normal blood pressure using a randomized double-blind placebo-controlled study. (1) Nineteen subjects (Age 48.9${\pm}$4.3, M/F;18/1) took a 100ml drink either containing 125${\mu}$g of VY or placebo twice daily for 4 weeks. The reductions of the systolic (SBP) and diastolic blood pressure (DBP) were observed in mild hypertensive subjects (n=5) with averages of 17.8${\pm}$2.5 mmHg (p<0.01 vs placebo) and 11.0${\pm}$2.0 mmHg(p<0.05 vs placebo), respectively. Neither SBP nor DBP changed in the subjects of both the placebo group and the high-normal blood pressure group. (2) A randomized double-blind cross-over placebo-controlled study was carried out in 10 mild essential hypertensive subjects (Age 50.6${\pm}$4.6, M/F;10/0). They took a 100ml drink either containing 62.5${\mu}$g of VY or placebo twice daily for 4 weeks alternatively with a 6-week interval. The percent changes in SBP and DBP were -6.9 % and -5.8 % (p<0.05) one week after the VY drink administration, respectively. No adverse effects such as coughing or allergic phenomena could be observed in any of the subjects of drinking VY during the experimental period. These results suggest that the drink containing at least 125${\mu}$g/day of VY may have a significant antihypertensive effect on mild hypertensive subjects without any adverse effects.

  • A cross-sectional study was conducted to investigate the effect of long term noise exposure on blood pressure among steel mill workers. The workers participated in periodic medical examinations performed from August 27 to September 6 in 1990. Examined were 1,034 workers with high-level noise exposure(average $91.8{\pm}5.2dB(A)$) and 390 workers with low-level noise exposure(average $75.2{\pm}4.6dB(A)$). No significant difference was found in systolic or diastolic flood pressure between the two exposure groups. Prevalence of hypertension (${\geq}160mmHg\;systolic\;or{\geq}100mmHg\;diastolic$) was higher in a younger age group (${\leq}40$ years old) of high-level noise exposure than of low-level noise exposure. However, the difference was not statistically significant. Furthermore, in younger ages, prevalence of hypertension appeared to be higher in the hearing loss group (${\geq}25dB\;at\;1000Hz\;or{\geq}40dB$ at 4000Hz in at least one ear) than in the normal hearing group. From multiple regression analysis, hearing loss, body mass index, age, alcohol and family history of hypertension were proven to be predictors of diastolic blood Pressure (p<0.02). When regression was performed for each age group, hearing loss was a strong predictor of diastolic pressure in the younger age group (p<0.01).

  • This study was carried out to obtain the basic data for epdemiological survey of hypertension in old population (60 years or more). From May, 1983 to April, 1984, 365 males and 335 females who inhabit in Ko-Chang Gun, Chonbuk Province were investigated for several factors as their socio-econmic status and laboratory examinations with blood pressure, and which factors were analysed by simple correlation and multiple regression analysis. The results are summarized as follows; 1) Sample size of this study is equivalent to 5.2%(male;6.7%, female;4.3%) of population in 60 years or more age group, and the mean age of samples is 70.6${\pm}$5.3 (yr.) in males and 71.4${\pm}$5.3 (yr.) in female (P>0.05). 2) Mean blood pressure of males are 135.9${\pm}$21.3mm Hg in systolic and 85.3${\pm}$13.4mm Hg in diastolic phase and in female, 131.0${\pm}$23.6 mm Hg and 84.1${\pm}$19.9 mm Hg (P < 0.01). Their prevalence rates of hypertension (${\geq}$ 140 mm Hg in systolic, ${\geq}$ 95 mm Hg in diastolic phases) are 33.7% in males, 40.6% in females (P < 0.01). 3) Serum cholesterol levels and other independent variables are revealed in normal ranges, and except to Vervaeck index (89.4${\pm}$5.6 in males, 87.5${\pm}$6.7 in females, p<0.01), other are not significant sexual differences (P>0.05). 4) In the simple correlation analysis, the main factors that affect to blood pressure are serum cholesterol levels (P < 0.05) and Vervaeck index (P < 0.01) in males, age (P <0.05) and Vervaeck index (P <0.01) in females. 5) In multiple regression analysis, prediction equations for blood pressure are calculated as follows; Ysm=-64.55+0.161(X1)+0.124(X2)-0.047(X3)+1.953(X4) Ydm=18.61-0.125(X1)+0.060(X2)+0.032(X3)+0.720(X4) Ysf=-0.22+0.536(X1)+0.134(X2)+0.068(X3+0.788(X4) Yaf=-14.46+0.685(X1)+0.033(X2)+0.176(X3)+0.362(X4) Ysm : Systolic blood pressure in male, Ydm : Diastolic blood pressure in male, Ysf : Systolic blood pressure in female, Ydf : Diastolic blood pressure in female.

  • The blood pressure measurement is calculated as a value corresponding to the pressure of the blood vessel using the pressure from the outside for a long time. Due to the recent miniaturization of measurement equipment and the ICT combination of personal healthcare systems, a system that enables continuous and real-time measurement of blood pressure with a sensor is required. In this study, blood pressure was measured using pulse transit time using Photoplethysmography. In this study, blood pressure was estimated by using systolic blood pressure. And it is possible to make measurement only with PPG itself, which can contribute to making a micro blood pressure measuring device. As a result, systolic blood pressure and PPG's S1-P and P-S2 were used to analyze the possibility of blood pressure estimation.

  • The purpose of this study was to compare the serum lipid level, blood sugar and blood pressure in vegetarians and non-vegetarians. The subjects of the study were 127 Buddhist nuns (age: 23∼79 y) from Oonmoon Temple in Choungdo district Gyeongsang Bookdo province and 118 Buddhist nuns practicing Zen meditation at Soodeok Temple in Yeosan district Chongcheong Namdo province. For control subjects, 235 healthy female adults (age: 23∼79 y) were selected. They were the nurses in the Gyeongsang National University Hospital, teachers and housekeepers living in Jinju, Gyeongsang Namdo province. The period of this study was from October 1996 to February 1997. The contents were consisted of food consumption survey, anthropometric measurement, estimated amount of energy expenditure, physical activity and clinical examination. The mean ages of the subjects were 44.2 y for vegetarians and 40.5 y for non-vegetarians, respectively. Average body mass index (BMI) of vegetarians and non-vegetarians were 22.47 and 21.08, WHR 0.85 and 0.84, percentage of body fat 28.79 and 26.55 respectively. The average duration of vegetarian diet of the vegetarians was 13.16 y. Levels of total cholesterol, LDL-cholesterol, atherogenic index (AI), diastolic blood pressure, blood sugar and HDL-cholesterol were significantly higher (p<0.01) in non-vegetarians than those of vegetarians. In both of subjects, levels of TG, total cholesterol, LDL-cholesterol, atherogenic index (AI) and systolic blood pressure were significantly higher (p<0.01) with an increment of age and the vegetarians showed a lower ratio of rise than the non-vegetarians. Levels of serum TG, LDL-cholesterol and AI were utmost in the 60 s and declined in the 70 s. Consequently, vegetarian diet can be considerably effective in reducing the level of the risk factors causing cardiovascular disease.

  • 연구목적: 고혈압환자의 효과적인 자가관리 간호중재를 개발하는데 필요한 기초자료로 혈압자가측정(self-monitoring of blood pressure)에 대한 특성, 장점, 범위 및 제한점을 파악한다. 연구방법: 1996년부터 2005년까지 PubMed에 수록된 고혈압환자의 자가관리 방법중 혈압자가측정방법이 포함된 외국의 연구를 중심으로 체계적인 고찰을 실시하였다. 전체 69개 자가관리방법을 적용한 논문 중에서 혈압자가측정이나 가정에서의 혈압측정(home monitoring)에 대한 45개 논문을 선정하여 분석하였다. 연구결과 전반적으로 혈압자가측정 방법은 고혈압환자의 혈압조절을 향상시키는 효과가 유의한 것으로 나타났다. 환자가 혈압을 자가측정한 방법에서 평균 혈압, 수축기 혈압, 맥압이 유의하게 감소한 것으로 보고되었다. 장기적 프로그램에서 혈압조절율이 향상되거나, 이완기혈압의 감소효과도 보고되었다. 혈압자가측정의 기준치는 연구마다 일치하지는 않았지만 135/85mmHg 수준이 정상혈압의 상한수준으로 제시되었다. 일부 연구에서는 가정 내 혈압측정이 24시간혈압측정을 대체하는 방법으로 추천되었다. 보다 정확한 혈압자가측정을 위해서 신뢰성 있는 혈압측정기구의 사용과 정확한 측정방법이 환자들에게 교육될 필요가 있다. 결론: 혈압자가측정은 고혈압환자의 혈압조절에 유용한 방법으로 고찰되었다. 또한 고혈압의 진단, 혈압치료와 고혈압 약물복용 행위를 향상시키는 교육적 효과도 긍정적으로 나타났다. 따라서 고혈압환자를 위한 효과적인 자기조절프로그램에 혈압자가측정법을 포함하는 것이 추천되며, 추후 한국에서 시도된 관련 연구에 관한 문헌고찰의 비교연구가 필요하다.

  • A comparison was made regarding the extent of anger between 50 hypertensives and 50 normotensives, using anger scale. In addition, correlation was investigated between the extent of anger and biological variables such as systolic and diastolic blood pressure, serum total cholesterol, high density lipoprotein(HDL) and triglyceride in each of both the groups. The two groups were matched to each other regarding age, sex, the level of education and body mass index(BMI). The hypertensives scored significantly higher than normotensives in anger suppression, whereas normotensives scored significantly higher than hypertensives in anger expression. In hypertensives, scores of anger suppression and anger expression did not significantly correlate with blood pressure, serum total cholesterol, HDL and triglyceride, respectively. In normotensives, however, scores of anger suppression correlated positively with systolic blood pressure. Male hypertensives scored significantly higher than female hypertensives regarding anger expression, whereas male normotensives scored significantly higher than female normotensives regarding anger expression and anger total subscale, respectively. These results suggest that hypertensives suppressed more anger than normotensives, and that anger suppression in normotensives was more likely to increase blood pressure, supporting the previous reports that suppressed anger may be related to hypertension.
