Purpose: This study was done to examine the relationship between nursing students' hearing levels and accuracy of blood pressure (BP) measurements. Methods: Participants were 107 students who had finished their fundamental nursing practice and clinical practicum and who used earphones. Data were collected from October 13 to November 30, 2014 and from April 30 to May 19, 2015. Students' hearing thresholds were examined using an audiometer. Students were assigned to take two BP measurements on BP measurement training simulators, but only the second measurement was used for analysis. Results: All nursing students' hearing levels were within normal range, and there was no significant difference found among the settings for diastolic blood pressure. However, there were significant differences between low systolic blood pressure (SBP) (below 120mmHg) and high SBP (over 140mmHg) (z=9.02, p=.011). Measurement error in SBP showed a positive correlation with hearing threshold in the right ear at frequencies of 1000Hz and 500Hz. Conclusion: Findings indicate that BP measurement error is correlated with hearing threshold at some frequencies. To reduce measurement error, nursing students should be provided with health education about hearing and to improve training for students, further studies need to examine other factors influencing BP measurement error.

As people's income and intake of animal fat rapidly increase, so does choresterol concentration in blood. Thus diseases such as non-insulin-dependent diabetes mellitus(NIDDM)myocardial infraction, high blood pressure, cerebral stroke resulting from atherosclerosis rapidly increase recently. It is very difficult to diagnose atherosclerosis early since its progress is so slow and there is no sypmtoms in the beginning of the disease. In this study a mechanical characteristic, compliance, of the lower leg arteries was measured noninvasively. Changes of blood volume and pressure were measured using impedance plethysmgraphy and mercury sphygmomanometer, respectively. The compliance was calculated by dividing the change of blood volume by the change of pulse pressure ( systolic-diastolic pressure ) . Subjects were 24 asymptomatic persons ranging (rom 30 Ic 58yeras and 14 diabetics from 41 to 59years. The compliances, mean, and systolic pressures were statistically analyzed using a t-test be- tween the healthy and diabetic groups. The average compliance of the healthy and diabetic group was measured 2.79 and 1.82U1/mmHg/cm, respectively and these were significantly different(p<0.01). It was also found that the compliance is a better parameter in differentiating the vascular disease than mean or systolic blood pressure.

Objectives : Recently, people who have normal brachial blood pressure(BP) are being threatened by high-risk disease such as stroke. The aim of this study is to suggest that new method to assess systemic circulation. It can be performed by analyzing optimal blood pulse wave on 3 sites belonging to subjects that have normal BP. Methods : We respectively extracted main peaks(h1) of optimal blood pulse wave on left/right temporal artery(LR1=h1), radial artery(LR2=h1) and dorsalis pedis artery(LR3=h1). We obtained h1 from 30 subjects who are discreetly chosen and have normal BP. Main peak(h1) can be extracted by using 3D pulse imaging analyser(DMP-1000+, DAEYOMEDI Co., Korea) that has 5-level pressure method. We analyzed the ratio of [LR1/LR2] and [LR3/LR2]. Results : In the case of male group, the results are [LR1/LR2=0.7100.177] and [LR3/LR2=0.9290.317]. In the case of female group, the results are [LR1/LR2=0.6680.121] and [LR3/LR2=0.7050.195]. Especially, it is statistically verified that the result of ratio [LR3/LR2] is much higher in male group than in female group(p<0.05). Conclusions : We suggested the standard ratio of [LR1/LR2] and [LR3/LR2] for normal subjects, respectively. It can be adopted as a new method to evaluate the systemic circulation.

Cheonghunhwadam-tang(CHT) have been used in oriental medicine for many centuries as a therapeutic agent of vertigo by wind, fire and phlegm. CTG was CHT adding Aurantii FructusㆍGastrodae Rhizoma. CTG was significantly increased regional cerebral blood f1ow(rCBF) in a dose-dependent, and CTG was decreased mean arterial blood pressure(MABP) compared with normal MABP(100%) in a low dosage, but was increased MABP in a dose-dependent, was aliked with normal MABP in a high-dosage. Therefore, purpose of this Study was to investigate experimental mechanism of CHTAG on the cerebral hemodynamics(rCBF, MABP) in rats. The changes of rCBF and MABP were determinated by Laser-Doppler Flowmetry(LDF). The results were as follows ; Pretreatment with indomethacin(3㎎/㎏, i.v.) was significantly inhibited CTG induced increase of rCBF and pretreated with propranolol(3㎎/㎏, i.v.) was inhibited CTG induced increase of rCBF, but pretreatment with methylene blue(10㎍/㎏, i.v) was increased CTG induced increase of rCBF. Pretreatment with indomethacin was decreased CTG induced increase of MABP, but pretreatment with propranolol and methylene blue were increased CTG induced increase of MABP. This results suggest that the mechanism of CTG is mediated by cyclooxygenase.

The aim of this study is to investigate whether milk fermented by Lactiplantibacillus plantarum K79, which exhibits angiotensin-converting enzyme inhibitory activity, has an effect on lowering the blood pressure of hypertensive rats and to investigate biomarker changes in their blood. Experimental group: normal group (NG, Wistar-Kyoto rats): distilled water, control group [NCG, spontaneously hypertensive rats (SHR)]: distilled water, high treatment group (HTG, SHR): 500 mg/kg/day, medium treatment group (SHR): 335 mg/kg/day, low treatment group (SHR): 170 mg/kg/day, positive control group (PCG, SHR): Enalapril, 10 mg/kg/day. The experimental animals used in this study were divided into groups composed of 8 animals. In terms of weight change, a significant difference was observed between the NG and the SHR group, but there was no significant difference between the SHR group. After 8 wk of feeding, blood pressure was lowered more significantly in the HTG (209.9±13.3 mmHg) than in the NCG (230.8±7.3 mmHg). The treatment group has an effect of lowering blood pressure by significantly suppressing blood pressure-related biomarker protein expression than NG. The results obtained can be used as an antihypertensive material in a variety of food raw materials.

목 적 : 비만은 고혈압의 위험 인자로서 소아 청소년기의 비만이 성인기의 비만으로 발전하기 때문에 결국 소아 청소년기의 비만으로 심혈관계 등 여러 문제가 유발된다고 볼 수 있다. 따라서 소아 청소년기 비만증에서 정확한 혈압의 측정은 매우 중요하겠다. 본 연구에서는 소아 청소년 비만 환자들을 대상으로 수시 혈압 측정으로 선별 검사한 후 이들의 24시간 혈압을 측정함으로 ABPM의 유용성과 의미에 대해 고찰해보고자 하였다. 방 법 : 2006년 2월 1일부터 2007년 12월 1일까지 한동대학교 선린병원의 소아 청소년과를 방문하여 ABPM을 시행한 모든 환자들을 대상으로 하였다. 자료의 분석은 수축기, 이완기 혈압측정을 수면 혈압과 이를 제외한 각성 혈압으로 나누어 분석하였고 야간 혈압 강하(night dip)를 평가하였다. 환자는 정상군(1군)과 체질량계수만 95 백분위수가 넘는 비만군(2군) 그리고 비만이면서 외래혈압이 120/80 mmHg이상인 비만 위험혈압군(3군)으로 구분하였다. 결 과 : ABPM을 시행한 환자는 모두 49명이었고 비만군이 18명이었고 비만 위험혈압군이 12명이었다. 정상군은 19명이었다. 각 군의 수축기 평균혈압을 비교하였을 때 모든 군에서 통계학적으로 의미 있는 차이를 나타내었고(1군, $105.1{\pm}4.7$; 2군, $111.0{\pm}7.1$; 3군, $117.8{\pm}6.6mmHg$), 이완기 평균 혈압의 경우 1군과 3군에서만 통계학적으로 의미 있는 차이를 나타내었다($69.1{\pm}5.3$, $77.9{\pm}6.3mmHg$). 각성 혈압을 비교한 결과도 1군과 3군간에만 통계적으로 유의한 차이가 있었다. 수면혈압인 경우 수축기 혈압은 3군이 1, 2군에 비해 통계적으로 유의하게 높았으나, 이완기 혈압은 다른 경우와 마찬가지로 1군과 3군간에만 유의한 차이가 있었다. 본 연구에서 각 군간에 야간 혈압 강하를 조사해보니 통계적으로 의미 있는 차이를 보이지 않았다. 결 론 : 본 연구에서 ABPM을 시행한 결과 비만 위험혈압군에서 통계적으로 유의하게 혈압이 높았다. 소아 청소년에서, 특히 향후 심혈관 질환 및 여러 질환의 위험인자로 알려진 비만아에서 ABPM의 적극적인 활용이 필요로 하겠다.

Objectives: The current study was performed to assess the distribution of intraocular pressure (IOP) and its association with metabolic syndrome (MS) in a community. Methods: We measured IOP and MS components from 446 adults, age 20 or more years old, who reside in a community in Kyunggi Province, South Korea. We compared the level of IOP according to the number of metabolic abnormalities and between normal and abnormal metabolic components. Linear regression analyses were used to determine the relationship between IOP and metabolic components. Results: No significant difference in IOP (mean${\pm}$SE) was found between men ($12.24{\pm}2.42$) and women ($12.55{\pm}2.41$ mmHg, p > 0.1), while IOP of men tended to decrease as age increased (p for trend < 0.01). After adjusting for age, IOP of subjects with abdominal obesity in men and high blood pressure in women were significantly higher than those without abdominal obesity or high blood pressure (p < 0.05). Female subjects with MS showed significantly higher IOP than those without MS. Participants with more metabolic disturbances tended to have a greater IOP elevation with a linear trend after adjusting for age and sex. In the univariate regression analysis, age and waist circumference were significantly associated with IOP in men, but systolic and diastolic blood pressure were associated with IOP in women. In final multiple regression model, age, systolic blood pressure, and triglyceride were associated with IOP in women, and age in men. Conclusions: These findings suggest that MS and its components may be important determinants of elevated IOP.

Imbalance in calcium and phosphorous metabolism due to aging or menopause leads to osteoporosis. In contrast to patients with normal blood pressure, hypertensive patients have a higher loss of calcium in the urine with its attendant risk of osteoporosis. The high blood pressure is associated with the risk of bone loss and abnormalities in calcium metabolism leading to calcium loss. So we retrospectively investigated the changes of bone mineral density (BMD) which drugs can have clinical influences over osteoporosis treatments of patients with calcium-antagonists as common antihypertensive drugs and with bisphosphonates which causes a most effective inhibition of osteoclasts resorption. As a result over 70 years of age group and within bisphosphonates group, alendronate 70 mg once-weekly group showed significant increase of BMD in lumbar area. Combination group of cilnidipine and $maxmarvil^{(R)}$ showed very significant decrease of BMD. In conclusion, it is desirable that combination therapy with calcium-antagonists is used carefully in the treatment of osteoporosis with high blood pressure.
