High-salted mineral water (Daehan Deep Water, Korea) that is pumped up from below the sedimentary rock layer of Dadaepo, Busan, Korea has a composition similar with that of deep sea water. Under the well-being boom, the mineral water is processed for various uses including washing or oral administration. However, high concentrations of various minerals in the mineral water are suspected to affect on the physiology of human body, especially on blood pressure (BP). Here, we examined the effect of Hot Mineral(R), dried powder of the mineral water, on the change of BP. Sprague­Dawley rats were grouped and orally administered $2.5\%$ Hot Mineral(R) (group M), $2.5\%$ NaCl (group S) or normal water (group C). Excreted urine was collected in metabolic cage for 24 hours. The systolic blood pressure (SBP) of the group S was remarkably increased (P<0.005) compared with that of the group M and the group C, which showed little changes of the SBP during 2 weeks. While average daily sodium intake were 0.32 mg in the group C, 6.64 mg in the group M and 4.07 mg in the group S, average daily sodium excretion were 11.37 mg, 53.70 mg and 7.75 mg, respectively. These results indicate that the sodium excretion in the group M was much higher than the other two groups. In this study, we suppose that the plenty amount of minerals such as calcium, potassium and magnesium in Hot Mineral? have an effect not to increase the SBP and to prompt sodium excretion out of the body. Therefore, these results suggest that oral administration of appropriate amount of Hot Mineral(R) for limited period does not induce increased SBP.

The causes of stroke are presumed hypertension, atherosclerosis,. cardiac disease, diabetes mellitus and old age and risk factors of stroke are suggested hypertension, hyperlipidemia. obesity, smoking and drinking etc. Especilly, hypertension is one of the most important cause and risk factor of stroke, therfore without therapy hypertension leads to stroke. The frequence of hypertension is significantly higher in hemorrhage patients of intracranial hemorrhage and subarachnoid hemorrhage. Antihypertensive therapy has an impact not only on the primary prevention of stroke but also on stroke recurrence and the declining of stroke motality has been attributed to the widespread availability and use of antihypertensive therapy. The goals of antihypertensive therapy decrease the complications and motalitv of cardiovascular system and prevent the promoting arteriosclerosis. In this study, we observed the blood pressure change of cb-hemorrhagic patients with hypertension who were hospitalized from 1996. 3. 1 to 1997. 2 .26 in Wonkwang Oriental Hospital. These patients had no antihypertensive therapy and were supplied herb med(Jaum sikpoongtang, Chungrijagamtang, Gojinumja) in medication. Our results suggested as follows. 1. Systolic and diastolic average BP at admission is $150.71{\pm}15.61mmHg$ and $95.00{\pm}8.8mmHg$ and this is hypertension state defining WHO 2. During one week in admission, the blood pressure demostrated a marked declination by SBP 8.97mmHg and DBP 6.22mmHg. 3. During two week in admission, the declination of SBP was significant in paired t-test(p<0.05) but, the declination of DBP was non-significant in paired t-test. 4. The blood pressure during third and fourth weeks gradually declined but, non-significant in test. According to the above results, we suggested that the BP declination Was affected by $Jamyang{\cdot}Jaum$ prescriptions in acute stage of cerebral hemorrhage.

본 연구는 고혈압전단계자들에 대한 지속적인 건 스트레치시 시간에 따른 생리학적 반응을 분석하여 정상혈압자와 고혈압전단계자에 대한 EPR의 한 요소인 기계적 수용기가 혈압 및 혈역학 반응에 어떠한 영향을 주는지를 검토하였다. 그 결과, 안정 시와 시간에 따른 혈압 반응은 고혈압전단계자에 있어 SBP, MAP가 평균 20sec에서 통계적으로 가장 높은 경향을 보였으며(p<0.05), 정상혈압자에서는 SBP, DBP, MAP가 평균 45sec에서 가장 높은 경향을 보였다(p<0.05). 이는 고혈압 전단계자의 지속적인 수동적 건 스트레치 시 정상혈압자에 비해 Group III mechanoreceptors의 역기능에 따른 상승된 혈압 반응이 초기에 나타내었다고 사료된다. 또한 혈역학 반응에서 안정 시와 비교하여 지속적인 수동적건 스트레치 시 고혈압전단계자에서의 HR, SV, CO, TPR 모두 유의한 차이를 보이지 않았으나 정상혈압자에서 SV, CO가 통계적으로 유의한 차이를 보였다(p<0.05). 이는 CO, SV, HR, TPR이 정상혈압자에 비해 고혈압전단계자에 있어 높은 경향을 나타내었지만, 혈역학 반응은 본 연구를 통해 차이를 보이지 않아 앞으로 연구가 필요할 것으로 사료된다.

혈압과 심박수의 중추조절에 대한 복외측 연수의 choline성 수용체의 역할을 규명하기 위하여 본 연구를 실시하였다. urethane으로 마취한 흰쥐에서 신경흥분성 아미노산인 L-glutamate(300 ng/site)를 복외측 연수에 미세주사하여 승압부위 (VLPA)와 감압부위 (VLDA)를 각각 기능적으로 확인하였다. VLPA와 VLDA에 각각 여러가지 choline성 약물들과 choline성 수용체의 길항제들을 양측으로 미세주사하여 다음과 같은 결과를 관찰하였다. 1. VLPA에 ca.bachol(300 ng/site)를 미세주사한 후 현저한 혈압상승 및 빈맥이 일어났으며, 이 반응은 hexamethonium ($4\;{\mu}g/site$)의 전처치에 의하여 차단되지 않았다. 2. VLPA에 physostigmine (200 ng/site)과 oxot.emo.me (300 ng/site)을 미세주사한 후 각각 현저한 혈압상승이 일어났다. 3. VLPA에 atropine($4\;{\mu}g/site$)을 미세주사한 후 현저한 혈압하강 및 서맥이 일어났다. 4. VLDA에 acetylcholine(500 ng/site)과 dimethylphenylpipe.azinium (500 ng/site)을 미세주사한 후 각각 현저한 혈압하강 및 서맥이 일어났다. 5. VLDA에 acetylcholine(500 ng/site)을 미세주사한 후 유발된 혈압하강 및 서맥반응은 hexamethonium($4\;{\mu}g/site$) 전처치에 의하여 차단되었다. 이상의 결과로 보아 흰쥐의 복외측 연수의 승압부위에서는 muscarine성 수용체를 통하여 혈압상승 및 빈맥반응이 일어나고 감압부위에서는 nicotine성 수용체를 통하여 혈압하강 및 서맥 반응이 일어나는 것으로 사료된다.

Background and Objectives: Blood pressure (BP) measurement using an auscultatory sphygmomanometer is recommended for diagnosing hypertension in children. As mercury sphygmomanometers (MSs) are banned owing to environmental concerns, it is crucial to determine the accuracy of mercury-free sphygmomanometers to replace them. We analyzed the accuracy of these devices to guide the National Survey selection. Methods: BP was measured thrice each with MS, auscultatory device (AD), and oscillometric device (OD) in 104 participants aged 10-18 using the National Survey data. The difference in BP was defined as the difference between MS and other devices. The BP differences, correlations, and influencing factors were analyzed. The frequencies of hypertension were also compared. Results: Systolic BP (SBP) and diastolic BP (DBP) differences between MS and AD were 0.88±3.36 mmHg and 0.63±3.95 mmHg, and those between MS and OD were 0.43±5.83 mmHg and 4.57±6.89 mmHg, respectively. The absolute error of <10 mmHg for DBP between MS and OD was 76%. The concordance correlation coefficient between MS and AD was 0.94 for SBP and 0.90 for DBP, and 0.81 and 0.67, respectively for MS and OD. Arm circumference negatively correlated with BP differences except for SBP between the MS and OD. The frequency of hypertension was not different between MS and AD but was underestimated by OD. Conclusions: AD correlated well with MS, while OD did not, especially for DBP. The superiority of AD over OD suggests AD as a possible alternative for MS in the National Survey.

Purpose: To determine the degree of cardiovascular disease risk according to socioeconomic factors among midlife women in the community and thereby provide baseline data for the development of health promotion programs. Method: A total of 200 women participated in health screenings and a health survey. The survey was performed in November and December, 2006. The survey instruments included socioeconomic factors, health behavior (smoking and exercise), and family history. Biophysical measurement included BMI and blood pressure. Blood samples were drawn for glucose and total cholesterol tests. Results: The mean age was 52.5 years, 34.0% had received education less than 6 years, 70.0% earned a monthly income of less than \1,500,000, and 61.5% were homemakers. Cardiovascular disease risk was significantly different by age (BMI, systolic BP, and exercise), education (systolic BP), monthly income (T. cholesterol), marital status (smoking), and occupation (exercise). Most women had 2 or 3 cardiovascular disease risks. Older age, lower education, and lower income were significantly associated with increased cardiovascular disease risk. Conclusion: Efforts should be made to decrease the number and severity of cardiovascular disease risk factors for midlife women in the community by developing health promotion programs targeting to modify their cardiovascular disease risk factors.

The present study was carried out to investigate the antihypertensive effect of a folklore herbal formulation (HF) (300mg/kg/day; p.o.) in deoxycorticosterone acetate (DOCA)-salt induced and fructose induced hypertensive rats. In DOCA model, DOCA (15 mg/kg, s.c., twice a week) was administered to unilateral nephrectomized rats for 4 weeks. In fructose model, drinking water was replaced with 10% fructose solution for 6 weeks to induce hypertension. Systolic blood pressure (BP) was measured once every week during the treatment schedule. After completion of treatment schedule, BP and vascular reactivity to various agonists like Noradrenaline, Adrenaline, Phenylephrine and Serotonin (5-hydroxytrptamine; 5-HT) were recorded in rats of both models. A cumulative concentration response curve of 5-HT was carried out in isolated rat fundus strip of the DOCA-salt induced and fructose induced hypertensive rats. The results tend to suggest that HF possesses antihypertensive activity.

결과적으로 본 연구에서 서로 다른 두 집단(RTG, ATG)의 비교시 저항성 트레이닝 집단(RTG)보다 유산소 트레이닝 집단(ATG)에서 산화질소(NO) 농도가 더 높게 나타났으며, 이는 지속적인 유산소 형태의 트레이닝이 간헐적인 저항성 형태의 트레이닝 보다 더 많은 산화질소(NO)가 생성 된다는 것을 알 수 있었다. 또한 심박수(HR)와 혈압(BP), 평균동맵압(MAP)의 감소에도 저항성 트레이닝(RT)보다는 유산소 트레이닝(AT)이 효과적이라는 것을 알 수 있었다. 그러나 유산소 트레이닝(AT)에 비해 저항성 트레이닝(RT)에서 유의하진 않았지만 산화질소(NO) 농도가 증가된 것은 주목할 만한 결과이다. 이러한 결과로 볼 때, 단기간일 지라도 혈관이완 및 자율신경계 도움을 줄 수 있는 것은 유산소 트레이닝(AT) 임을 알 수 있었고 이는 일반적으로 운동을 선택할 시(근력과 근비대를 제외한 운동) 도움을 줄 수 있다고 사료된다. 또한 추후 연구에서는 12주 이상의 장기간의 트레이닝을 통해 저항성 트레이닝(RT)이 혈관이완의 직접적인 척도인 산화질소(NO) 농도에 관한 연구가 필요시 된다.

This study was performed to offer the fundamental data for preventing and controlling the cardiovascular diseases of rural community women. The number of 168 women aged 40 to 50s who live in Kumsan-gun, Chungnam were selected for analysis after medical examination by a Kumsan-gun health center during the period of November to December in 1996. Total cholesterol(TC), triglyceride(TG), high density lipoprotein cholesterol(HDL-C), blood pressure(BP), degree of obesity(BMI) and atherosclerosis index(AI) were measured and relation between these physical measurements to serum lipid levels were studied. The results were as follows; 1. Mean TC level, TG level, BP, BMI and AI were significantly increased with advancing age. 2. Mean TC level, TG level, BMI and AI of borderline BP group and hypertension group were significantly increased than those of normal BP group. 3. Mean TC level, TG level and AI of obesity group were significantly increased than those of normal BMI group. 4. Simple correlation analysis showed that the positive correlation between TC, TG, BP, BMI and AI, but the level of HDL-C was negative correlation with TG and AI. 5. In multiple regression analysis taking HDL-C level as the dependent variable and TG, TC, BP, BMI, Age AI as the independent variable, AI, TG, BMI, TC were significantly related to HDL-C.
