The purpose of this study is to determine cardiovascular reponses to concentric, eccentric and isometric exercise applied to the knee extensor muscle group. Exercise types studied were concentric, eccentric and isometric. The subjects were sixty healthy male volunteers who had no hypertension or cardiac disease. Heart rate, systolic and diastolic blood pressure were recorded prior to starting exercise. The subjects also performed 10RM on right lower extremity. A N-K table was used for three exercises to right knee extensors. Each exercise was selected randomly and applied to each subject 10 times in a 10 second. After each exercise, heart rate, systolic and diastolic blood pressure were recorded immediately. Findings were as follows concectric contractions had a greater effect on the increase of systolic blood pressure and heart rate than eccentric or isometric contractions. Diastolic blood pressure is influenced only by isometric contractions. Eccentric contractions have less effect on the increase of systolic blood pressure and heart rate than concentric or isometric contractions. We hope that the results of this experiment can be adapted to exercise programs for patients with cardiac disease.

The purpose of this study was to test whether moderate alcohol consumption has any positive effect on lowering blood pressure among Koreans. Study subjects were Korean adults 20 years or older (n=5,234) who participated in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES). Analysis of variance and analysis of covariance were used to construct univariate and multivariate models relating alcohol consumption to blood pressure for the analysis. After adjustment for possible covariates, drinkers (regardless of drinking level) had significantly higher systolic and diastolic blood pressure, compared with never-drinker for male subjects. Diastolic and systolic blood pressures were also significantly elevated with the drinking frequency and amount of alcohol intake among male subjects. For the female subjects, only diastolic blood pressure was significantly associated with the alcohol consumption at multivariate model. however, low level alcohol consumption did not show any sign of lowing effects on blood pressure. The result implies that moderate alcohol consumption did not have any positive effect on lowering blood pressure among Koreans for either sex.

This study was done to investigate the blood pressure, BMI and serum lipids of cerebrovascular accident patients in Seoul. The subjects were 195 Korean urban cerebrovascular accident patients who were hospitalized at Dong Seo Oriental Hospital in Seoul from June, 1997 to December, 1997. There were more cerebral infarction patients(164) than cerebral hemorrhage patients(31). Cerebral infraction patients were prevalent for subjects in their sixties, but cerebral hemorrhage patients were most commonly in their fifties. The BMI of cerebral infarction accidents was significantly higher than that of cerebral hemorrhage patients(p<0.05). Mean diastolic blood pressure of cerebral hemorrhage patients was significantly higher than that of the cerebral infarction patients(p<0.05). The mean systolic blood pressure of the cerebral hemorrhage patients was higher than that of the cerebral infarction patients, not statistically significant. The serum total cholesterol and glucose levels of the cerebral infarction patients was significantly higher than those of the cerebral hemorrhage patients(p<0.05). Serum total cholesterol(p<0.01), triglyceride(p<0.05) and LDH(p<0.01) levels of female subjects were significantly higher than those of male subjects. Serum total cholesterol has a negative correlation with serum GOT and GPT, but has a positive correlation with triglyceride. Serum triglyceride has a negative correlation with diastolic blood pressure but has a positive compellation with serum glucose.

15 patients with constrictive pericarditis who underwent interphrenic pericardiectomy from January, 1981 to April, 1983 and 11 patients who underwent radical pericardiectomy from May, 1983 to September, 1984 were compared to the clinical improvement and the results of pre- and postoperative cardiac catheterization. In the group of partial pericardiectomy the pericardium was removed anteriorly from the left phrenic nerve to the right phrenic nerve and in the group of radical pericardiectomy the pericardium was removed from almost entire surface of the heart including diaphragmatic surface and posterior wall of the left ventricle. The following results were obtained. 1. Both group of the patients showed marked symptomatic improvement early after operation. 2. The central venous pressure was decreased significantly after operation in both group of the patients. 3. The right atrial mean pressure and pulmonary arterial mean pressure decreased significantly after operation in both group of the patients and there was no significant difference in the amplitude of decrease between the two groups. 4. The right ventricular end-diastolic pressure and left ventricular end-diastolic pressure were decreased postoperatively in both group of the patients and the patients of the radical pericardiectomy showed more decrease than the patients of interphrenic pericardiectomy, and in the group of radical pericardiectomy the right and left ventricular end-diastolic pressure were normalized postoperatively but in the group of partial pericardiectomy they showed abnormally high pressure persistently. 5. The ejection fraction showed normal level pre- and postoperatively in both group of the patients.

Purpose: The aim of this study was to examine the characteristics of hypertension-related nursing intervention programs and their effects on systolic and diastolic blood pressure. Methods: Fifteen studies were selected from four databases (Korean studies, Riss4U, RICHIS, and JKAN) published as of 2009. They were analyzed by meta-analysis method. The selected studies contained a control group with pre-test and post-test design, measured blood pressure as a dependent variable, and used a reported statistical value for blood pressure to measure the size of effects. Results: The hypertension-related nursing intervention programs were relatively effective in lowering both systolic and diastolic blood pressure, although they were more efficient to decrease diastolic pressure. Among the hypertension-related intervention programs, complementary and alternative therapies were more effective in lowering blood pressure compared to lifestyle change intervention. Conclusions: To acquire substantial data of intervention effects, and complementary and alternative therapy, subjects in pre-hypertensive stage, and elderly people, better industrial and scholastic research methods need to be developed for future research. Further studies are needed to establish complementary and alternative therapies. Studies with different group of participants and studies using effective research design are in need as well.

Purpose: To investigate the hemodynamic risk factors for necrotizing enterocolitis (NEC), we analyzed the characteristics of descending aorta (DA) blood flow in preterm neonates, who later developed NEC. Methods: This was an observational case-control study on 53 preterm neonates at a tertiary referral center. Clinical and echocardiographic data were collected from 23 preterm neonates with NEC (NEC group), and compared with those of 30 preterm neonates without NEC (control group). Echocardiography was done at a median (interquartile range) of 5 (3-9) days after birth and 2 (1-2.5) days before the diagnosis of NEC. Results: Basic clinical characteristics including gestational age, birth weight, Apgar score, breast feeding status, use of umbilical catheters, and mode of invasive ventilator care were similar between the groups. Compared with the control group, the lowest diastolic velocity of DA was significantly decreased, whereas the diastolic reverse flow and the ratio of diastolic reverse to systolic forward flows were significantly increased in the NEC group. In addition, the resistive index (RI) of DA was significantly increased in the NEC group and showed a positive association with the development of NEC. Multivariate logistic regression analysis showed that increasing RI of DA was an independent risk factor for the development of NEC (P=0.008). Conclusion: Significant changes in DA flow characteristics including decreased diastolic velocity and increased diastolic reverse flow along with increased peripheral vascular resistance were observed before the development of NEC in preterm neonates. These findings may help clinicians stratify in advance neonates at a risk of developing NEC and may help improve outcomes in these neonates.

Background: Thoracic aortomyoplasty is one of the surgical treatment for heart failure and has advantages over artificial heart or intraaortic balloon pumps. It uses autogenous skeletal muscles and solves problems such as energy source. However its use in clinical settings has been limited. This preliminary study was designed to develop surgical technique and to determine the effect of acute descending thoracic aortomyoplsty. Material and Method: Thirteen adult Mongrel dogs were used. The left latissimus dorsi muscle was wrapped around the descending aorta under general anesthesis. Swan-Ganz and microtipped Millar catheter were used for the hemodynamics and endocaridial viability ratio. Data were collected with myostimulator on and off in normal hearts and the ischemic hearts. Result: In normal hearts, the mean aortic diastolic pressure increased from 72$\pm$15mmHg at baseline to 78$\pm$13mmHg with stimulator on. Coronary perfusion pressure increased from 61$\pm$11mmHg to 65$\pm$9mmHg. Diastolic time increased from 0.288$\pm$0.003 msec to 0.290$\pm$0.003msec. Systolic time decreased from 0.164$\pm$0.002msec to 0.160$\pm$0.002 msec. Endocardial viability ratio increased from 1.21$\pm$0.22 to 1.40$\pm$0.18. In ischemic hearts, mean aortic diastolic pressure incrased from 56$\pm$21mmHg at baseline to 61$\pm$15mmHg with stimulator on. Coronary perfusion pressure increased from 48$\pm$17mmHg to 52$\pm$15mmHg. Diastolic time increased from 0.290$\pm$0.003 msec to 0.313$\pm$0.004msec. Systolic time decreased from 0.180$\pm$0.002 msec to 0.177$\pm$0.003 msec. Endovascular viability ratio increased from 0.9$\pm$0.31 to 1.1$\pm$0.31. The limited number of cases ruled out the statistic significance. Conclusion: Descending thoracic aortomyoplasty is a simple operation designed to use patient's own skeletal muscles. It trends to increase diastolic augmentation and coronary perfusion pressure. Modification of surgical technique and stimulator protocol would maximize the effect to assist the heart.

Objective : The aim of this research was to investigate the depressive effect of acupuncture on Dong and depletion on Fungchi-point(G20) in stroke patients. Methods : We measured the blood pressure of the patients who were admitted in the Oriental Medical hospital of Dongeui medical center from 21. Dec. 2001. to 2. Oct. 2002. 41 stroke patients were devided into two groups. 15 patients were treated by acupuncture on Dong. The other 26 patients were treated by depletion on Fungchi-point(G20). The activity of daily living was measured. If systolic blood pressure was over 160 mmHg or diastolic blood pressure was over 90mmHg, acupuncture on Dong and depletion on Fungchi-point(G20) were performed. Then 30 minutes and 60 minutes later, systolic. diastolic blood pressure and pulse rates were measured. Results : After 30 minute of treatment, both acupuncture on Dong and depletion on Fungchi-point(G20) significantly depressed systolic blood pressure and diastolic blood pressure. After 60 minute of treatment, both acupuncture on Dong and depletion on Fungchi-point(G20) were significant in depressing systolic blood pressure and diastolic blood pressure. Pulse rates significantly changed in depletion on Fungchi-point(G20) but did not significantly change in acupuncture on Dong. Conclusions: These results suggest that both acupuncture on Dong and depletion on Fungchi-point(G20) are effective in depressing systolic blood pressure and diastolic blood pressure.
