In order to analyse the prevalence rate of hypertension and the actual conditions of control, we selected five districts out of eleven eups and myuns in Chinan Country. We administered structured questionaries to 309 adults above the age of 40, computerized the data using SPSS - PC+. More than 40.1% of adults over 40 in Chinan County have health disorders ranging from high blood pressure to hypertension including alert high blood pressure at 36.2%, relatively high. Among general characteristics, differences in the rate of hypertension were influenced by age, occupation and places of residence. Over 71 who are engaged in agriculture, who don't have jobs, who reside in Sungsu, Jungchun, Chinan-eup all have higher hypertension rates than other groups. Accordingly, the control of hypertension should be focused on these people. As a result of the control of blood pressure, the survey showed 93.0% of the subjects were checked mainly at hospitals clinics, health centers subhealth centers and community health posts more than once a year, relatively high level of blood pressure management. However, the difference between their blood pressure measurements at ordinary times and the level of blood pressure at the time of research was quite considerable. Only 47.3% of the subjects diagnosed with high blood pressure and 70.3% of the subjects with normal blood pressure recognized their blood pressure accurately 52.7% of the subjects diagnosed with high blood pressure showed errors in understanding their blood pressure at normal times. Because these errors can cause problems in the control of blood pressure, proper management should be executed through a systematic examination. As a result of the high blood pressure control condition, the average period of hypertension was 74.5( ${\pm}92.8$) months, 92.3% of the subjects were diagnosed with high blood pressure at hospitals clinics, health centers subhealth centers community health posts, but only 29.5% were examined after a general check up on high blood pressure was completed. 70.5% were diagnosed with high blood pressure only after measuring their blood pressure. 14.1% of the subjects were hospitalized because of falls influenced by high blood pressure. 33.3% attended hospitals and health centers regularily for medical treatment and this shows how low the rate of the control of blood pressure. Most people did not undergo medical treatment, because they had no painful symptoms (46.7%), they didn't need to take the medicine(28.9%), or they forget to take the medicine(20.0%). These problems in the control of hypertension were discovered in the process of diagnosing high blood pressure at health medical institutions. Many people did not recognize the need for consistent control of blood pressure. That is, although the diagnosis for high blood pressures performed at hospitals clinics, health centers subhealth centers and community health posts, was 92.3%, more than 70.5% of the subjects were not examined completely with regard to blood pressure. Accordingly, heath medical institutions must diagnose high blood pressure not only by only measuring blood pressure but also by using systematic process of examination. As for the people diagnosed with high blood pressure, one should perform consistent medical approaches and help them to recognize the importance of the continuous control of blood pressure through subject-oriented education. Problems the subjects experienced were the following numbness in the limbs easily paralyzed stitches in their shoulders which felt painful, stiff necks, occiputs felt heavy, headaches when they got up in the morning, felt dizzy when standing and moving their heads and poor eyesight. The rate of knowledge related to high blood pressure was 78.7 points, comparatively low. Whether they had normal blood pressure or hypertension made no difference. These results are not desirable. Adult-oriented education forgot the prevention and management of high blood pressure should be implemented. Hypertensive-oriented education should be especially reinforced. Because there was a difference in the level of knowledge according to age, academic career, occupation or place of residence, education related to hypertension should be intensified and focused on those over the age of 71 those who did not attend school, those who do not have jobs and are engaged in agriculture and residents living in Bugui, Jungchun regions. The degree of healthy life practice in hypertensives is poor, particularly weight control, as opposed to people who have normal blood pressure. It makes no difference in smoking, the amount of daily smoking, drinking, the control of salt because each result means that they are not practicing healthy life or modifying their life-style. The development and programs to improve a healthy life should be executed.

Extremely low birth weight infants remain at increased risk of intraventricular hemorrhage from the fragile vascular bed of the germinal matrix; the roles of hypotension (ischemia) and reperfusion (hyperemia) in the development of intraventricular hemorrhage are still debated. Cerebrovascular pressure autoregulation protects the brain by maintaining constant cerebral blood flow despite changes in blood pressure. The ontogeny of cerebrovascular pressure autoregulation has not been well established and uncertainty remains about the optimal arterial blood pressure required to support brain perfusion. Another important aspect of premature cerebral hemodynamics is the critical closing pressure--the arterial blood pressure at which cerebral blood flow ceases. Interestingly, in premature infants, the critical closing pressure approximates the mean arterial blood pressure. Often in this unique population, cerebral blood flow occurs only during systole when the diastolic arterial blood pressure is equal to the critical closing pressure. Moreover, the diastolic closing margin, a metric of cerebral perfusion that normalizes diastolic arterial blood pressure to the critical closing pressure, may be a better measure than arterial blood pressure for defining cerebral perfusion in premature infants. Elevated diastolic closing margin has been associated with intraventricular hemorrhage. This review summarizes the current state of understanding of cerebral hemodynamics in premature infants.

Objective: The effect of lead on blood pressure remains controversial in spite of the numerous studies which have been conducted in the recent years. The aim of this study was to evaluate the effects of exposure to lead on blood pressure among non-smokers. Methods: In this cross sectional study, 1416 male and female non-smokers were enrolled, aged 20 years or older, from the Korean National Health and Nutrition Examination Survey 2008. Blood pressure, blood lead levels (BLLs), height, weight, and cotinine level were measured for all subjects. Results: Geometric mean BLLs of the participants was 2.20 ${\mu}g$/dl. BLLs were higher in the older, male, and lower education groups than the younger, female and higher education groups. After adjusting for age, sex, education and BMI through multiple regression analysis, a significant positive association between systolic blood pressure (p = 0.0357), diastolic blood pressure (p = 0.0111) and BLLs. Also, among the normal BMI group (18.5 kg/$m^2$ < BMI < 25 kg/$m^2$), we also found a significant positive association between diastolic blood pressure and BLLs (p = 0.0370). Conclusion: The present study showed that blood lead serves as a good predictor of blood pressure changes and that there was a statistically significant association between blood lead and blood pressure, especially diastolic blood pressure.

Hemorrhage shock occupies high rate in trauma patient's mortality and blood pressure is the variance that judges early diagnosis and the effect of remedy. Systolic blood pressure is related to pulse transit time(PTT). PTT means the time that is required to flow from the heart to peripheral artery. PTT is influenced from the length, cross section and stiffness of the blood vessels. It is hard to evaluate the correlation between systolic blood pressure and PTT because they are variable in human body. In this paper, we evaluated the correlation between the systolic blood pressure and PTT in normal and hemorrhage states using standardized rat. PTT is defined as the time differences between the R peak and the peak of pulse wave. The analyzed time differences of ECG and blood pressure are analyzed every 5minutes for 30 seconds when there is before and after bleeding. Before bleeding, systolic blood pressure and PTT are steadily preserved but when the bleeding comes started, systolic blood pressure is declined. However PTT was increased and decreased. Under the circumstance that the standardized rat is controlled by age, the length of the blood vessels, and any disease, it shows that PTT measurement using systolic blood pressure of bleeding is impossible.

Purpose: We gathered information for the development of a blood pressure measurement education program by analyzing the accuracy of reading taken using a blood pressure simulator by Korean paramedic students. Methods: Data from 131 students were collected in November 12-20, 2013, and April 2-4, 2014. A 27-item questionnaire was administered, the accuracy of measurements confirmed using a blood pressure simulator (BT-CEAB), and the data analyzed (SPSS v 21.0). Results: The accuracy of systolic and diastolic blood pressure readings (${\leq}2mmHg$) was relatively low (27.5%). The mean blood pressure knowledge score was 67.61 points; significant differences were noted considering the sex (p = .001), hours of practice (p =.007), numbers of practice (p = .001), and reported self-confidence (p = .026). The blood pressure measurement accuracy group did not show a significant difference in its knowledge of blood pressure (p = .198). Conclusion: Most subjects needed several practice sessions to master the skill of measuring blood pressure. The feedback provided by individual assessment and the practice education program will serve as the basis for clinical and prehospital practice.

Objectives : The aim of this study was to investigate the antihypertensive effect of S'NC nerve control treatment in hypertensive patients. Methods: We measured the blood pressure of 5 patients who were admitted in the Oriental Medical Clinic of S'NC Medicine Research Institute from 19th April 2007 to 29th June 2007. Eligible participants had systolic blood pressure ${\ge}$140mmHg or diastolic blood pressure ${\ge}$90mmHg. Blood pressure measurements were after the patient had been in bed rest for at least 10 min. Ten sessions of S'NC nerve control treatment over 2 weeks were performed in the patients. Blood pressure were measured twice before and after each treatment. Results : After 2 weeks, blood pressure reduction was observed in the treatment patients, with an average decline of systolic blood pressure up to 21mmHg and diastolic blood pressure up to 20mmHg. But, there were not statiscally significant The effects of S'NC nerve control treatment by measuring time on blood pressure were as follows: In a systolic blood pressure(p=0.087) and diastolic blood pressure(p=0.609) was gradually deceased not significantly from 1st to 10th. Conclusion: These results suggest that S'NC nerve control treatment may be efficacious in decreasing arterial blood pressure in hypertensive patients. Controlled trials investigating the efficacy of S'NC nerve control treatment for lowering blood pressure are warranted.

Objectives: Blood lead and hyperhomocysteinemia have been found to be associated with cardiovascular disease. The objective of the present study was to assess the relationship of lead biomarkers on plasma homocysteine and blood pressure. Methods: To evaluate the effect of lead biomarkers including blood lead on plasma homocysteine and blood pressure in retired lead workers, 66 retired lead workers without any occupational exposure to organic solvent, mercury and arsenic were agreed to participate this study. For the control subjects 42 controls were recruited from same area of retired lead workers with consideration of demographic characteristics. Results: The mean levels of blood lead and ZPP of retired lead workers were significantly higher than control group. There were positive significant correlations between blood lead and plasma homocysteine, also systolic and diastolic blood pressure. The multiple linear regression analysis also reveled that plasma homocysteine was significantly associated with blood lead after adjusting for age, gender, body mass index, lead exposure, smoking and drinking. Diastolic blood pressure was significantly associated with blood lead, plasma homocysteine, and total cholesterol; whereas, systolic blood pressure was significantly associated with plasma homocysteine only. Conclusions: Blood lead showed significant association with plasma homocysteine and blood pressure even after more than mean 10 years from their retirements.

High blood pressure (HTN) is a condition in which blood pressure is kept higher than normal. Blood pressure trait measures systolic blood pressure (SBP) which is the highest pressure and diastolic blood pressure (DBP) which is the lowest blood pressure. Pulse pressure (PP) is the difference between systolic and diastolic blood pressure. Hypertension is known as a disease caused by the interaction of the environment and genetic factors. To date, studies have been conducted to find genes associated with hypertension. Genome-Wide Association Study (GWAS) analysis using European data from the UK Biobank reported new 535 loci were associated with blood pressure trait. Among them, 12 genes have been reported to have a significant correlation with SBP, DBP and PP. In the study, 12 genes polymorphisms were extracted based on KARE (Korean association resource) and then we performed linear regression of blood pressure trait. As a result, 6 SNPs of the 3 genes (rs12355413 and rs11006736 of ARMC4, rs2290883, rs2290884 and rs11039014 of LRP4, rs7234941 of BCL2) showed statistically significant correlation (P<0.05) with blood pressure trait. Of the 3 genes, 6 SNPs in 2 genes (rs9651357, rs12355413, rs11006736, rs1889522 of ARMC4 and rs4987774, rs7234941 of BCL2) showed significant correlation with hypertension. These results suggest that genetic polymorphisms of ARMC4, LRP4 and BCL2 genes are associated with blood pressure traits and hypertension in Korean population. Moreover, we expected to help understand the pathogenesis of hypertension.
