The purpose of this study was to investigate the effect of germinated buckwheat on blood pressure, plasma glucose and lipid levels of spontaneously hypertensive rats(SHR). The male and female SHR were divided into two groups. After feeding the germinated buckwheat diet(50%, w/w) ad libitum for 6 weeks, the weight gain of the germinated buckwheat group in male rats was higher than those of control group. Systolic blood pressure of the germinated buckwheat group in male rats was significantly decreased at 6 weeks by 3%. The fasting glucose levels of the germinated buckwheat group had a tendency to be lower compared with those of the control group. Total cholesterol, HDL-cholesterol and HTR of female SHR fed the germinated buckwheat diet were significantly increased compared to the control diet. Atherogenic index of the germinated buckwheat group was decreased in males(ns) and females(p<0.05) than those of the control group. From these results the germinated buckwheat might be useful for anti-hypertensive and anti-hyperlipidemic agents.

In this paper, we proposed noninvasive and continous measurement of blood pressure using pulse transit time(PTT) and physical characteristic parameters and verified its clinical effectiveness. PTT can be obtained by electrocardiogram and phtoplethysmogram. There are many researches for estimating blood pressure using PTT which can be used for individual. However, it is not enough for extracting general regression equation which can estimate blood pressure for unspecified people. In this study, we suggested the regression equatin using PTT and physical characteristic parameters related to blood pressure and did measure blood pressure of many people. we compared the performance between two methods. As the results, we knew that the regressin model using PTT combined with physical characteristic parameters can estimate blood pressure more acurately and is closer to American National Standards Institute of the Association of the Advancement of Medical Instrument(ANSI/AAMI).

Because worldwide interest in the health is increased, the real-time health monitoring system has been demanded to be more convenient non-contact and precise medical devices than conventional. Therefore we developed the blood pressure monitoring system using UWB(Ultra Wide Band) radio wave which contact to the human body through the radar and continuously collect a movement signal of the blood vessel. Then the collected data including pulse rate, systolic blood pressure, diastolic blood pressure is processed in real time. The system monitors and controls through a program-based embedded LCD(Liquid Crystal Display) using Qt GUI(Graphic User Interface) to be displayed in real time. We implement the system as a embedded system because of reducing the size of the limited resources. Existing PC GUI design mode is used relatively large memory, therefore it requires more CPU(Central Processing Unit) capacity and processing time.

This study aims to evaluate the effect of mobile health intervention for employees with diabetes. The study subjects were 101 employees having fasting blood glucose over 100 mg/dL. The study participants were educated to check their blood sugar before meals every day, and received text messages to help improve general lifestyle habits for blood sugar, diet, and exercise for 12 weeks. There was a sufficient difference in blood sugar, body mass index and blood pressure before and after the intervention. As a result, fasting blood glucose(129.38±1.95 to 123.63±1.82) decreased(P<0.001). Body mass index(26.20±0.29 to 25.81±0.28, P<0.000), diastolic blood pressure(124.60±1.03 to 122.56±1.05, P<0.032), and systolic blood pressure(79.86±0.83 to 78.06±0.79, P<0.017) decreased, which were also statistically significant. It is expected that this study will be used as basic data to develop a self care program by using mobile and apply it to employees with diabetes.

In this study, detection system of the blood flow variation rate was implemented using the variation effect of bio electric impedance at time of the blood pressure measurement by means of impedance method. The blood pressure measurement was performed by the oscillometric method. The mean arterial pressure was calculated using maximum amplitude algorithm. The systolic and diastolic pressure were estimated by establishment of the various characteristic ratio according to mean arterial pressure range. Alternative static current source and lock_in amplifier were introduced to impedance measurement. The variation of blood volume was measured using variation bio impedance according to induced cuff pressure at measuring area.

The gallbladder(GB) polyps have malignant potential and nowadays are increasing due to the extended use of ultrasonography. Even though there are various reports on the risk of GB polyps, there is few study on the relationship between the presence of metabolic syndrome including serum biochemistry, lifestyle and the development of gallbladder polyps in korean population. The aim of this study is to establish a relationship between the presence of metabolic syndrome including serum biochemistry and the development of gallbladder polyps in korean population. This study conducted on 151 men and 167 women who visited a musculoskeletal hospital in Gyeonggido to have an ultrasound scan of the abdomen from November 2, 2012 to January 31, 2014. They are randomly selected to evaluate the prevalence risk factors were analyzed by comparing various variables between the GB polyp positive and negative. The collected data were analyzed using the personal computer program SPSS version 20.0 for windows. The mean size of the GB polyps was 3.92mm in diameter. Size of GB polyps were less than 10mm in diameter. As to frequency in the people with the GB polyps, the number of patients with the GB polyps was 184(57.9%): the number of metabolic syndrome of them was 114(26.4%); these results showed that risk of the GB polyps got higher at patients with metabolic syndrome. As to the risk of the GB polyps, people with the GB polyps had significantly higher risk than those without the GB polyps, as follows: The risk was significantly 1.061 times higher by weight; 1.186 by BMI; 1.060 by systolic blood pressure; 1.030 by diastolic blood pressure; 1,009 by Total cholesterol; 2.736 by metabolic syndrome; 1.011 by blood sugar on an empty stomach; 1.064 by ESR. The risk factors of GB polyps were found to be weight, BMI, total cholesterol, Triglycerol, Glucose, systolic blood pressure, diastolic blood pressure, ESR and metabolic syndrome. This study has a possibility to be used an indicator to identify the GB polyps, and in the future larger-scale study will have to be conducted to objectify it.

The purpose of this study was to identify the association between regular physical activity (PA) types and metabolic syndrome (MetS) in fertile women. Data were obtained from the seventh Korea National Health and Nutrition Examination Survey (KNHANES VII-3, 2018). The sample consisted of 4,172 fertile women over 19 years of age. The data were analyzed using an independent t-test, χ2 test, and multiple logistic regression analysis for examining the association of regular PA and MetS. The prevalence of MetS in fertile women was 3.1% (n =128), and 1,972 fertile women (47.2%) practiced regular PA. Compared to the non-regular PA group, regular PA resulted in a significantly lower systolic blood pressure (p =.002), lower waist circumference (p <.001), lower fasting blood sugar (p =.007), and higher high-density lipoprotein cholesterol (p <.001). After controlling the confounding variables, multiple logistic regression showed that the regular PA group (odds ratio 0.59, 95% confidence interval 0.35-0.98, p =.040) and the regular muscle-strengthen PA group (odds ratio 0.34, 95% confidence interval 0.14-0.80, p =.013) were associated with a decreased risk of MetS. Therefore, regular PA, including muscle-strengthen PA should be considered to develop effective MetS intervention in fertile women.

Purpose: Obesity is rapidly increasing in Korean children. Obesity is a risk factor for cardiovascular morbidity and is frequently associated with hypertension, diabetes mellitus and coronary artery disease. This study was designed to evaluate risk factors of the metabolic syndrome in obese children. Methods: From February 2000 to June 2004, eighty eight obese (body mass index ${\geq}95th$ percentile) children aged 4 to 15 years were included. We measured serum lipid levels (total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol), fasting sugar levels and insulin levels. Insulin resistance was determined by homeostasis model assessment, fasting insulin/glucose ratio and quantitative insulin sensitivity check index. Results: Clustering of risk factors for the metabolic syndrome in obese children demonstrated that 60.2% had more than one risk factors. Hypertension (14.8%), hypertriglyceridemia (14.8%), HDL-hypocholesterolemia (14.8%), LDL-hypercholesterolemia (12.5%) and hyperinsulinemia (12.5%) were observed. As BMI increased, there was statistically significant increase in systolic blood pressure, insulin and insulin resistance values. Insulin resistance was correlated to systolic blood pressure, serum lipid and insulin levels. The more risk factors for the metabolic syndrome obese children had, the higher was their insulin resistance. Conclusion: The increase in insulin resistance and clustering of risk factors for the metabolic syndrome are already apparent in obese children. Monitoring these risk factors for the metabolic syndrome should become a part of routine medical care for obese children.

Purpose : Pulse wave velocity (PWV) and ankle brachial index (ABI) are simple, non-invasive methods to assess arterial stiffness. These parameters are also known to be closely related to cardiovascular risk factors and diseases. The purposes of this study were to measure blood pressure, PWV, ABI in healthy Korean adolescents, set up their normal values and assess their correlations. Methods : Three hundred ninety two healthy adolescents (213 boys and 179 girls) underwent measurement of brachial ankle pulse wave velocity (baPWV), ABI, body mass index(BMI) and blood pressure from four extremities. Linear regression analysis was performed to reveal the correlations between PWV, ABI and independent variables. Results : Blood pressure and PWV were significantly higher in all extremities in males compared to females. Blood pressure of both brachial and ankle showed positive correlation with body weight, height, and BMI, whereas ABI showed no correlation with any of these indices. Conclusion : Blood pressure increases as body weight, height and BMI increases. PWV shows positive correlation with blood pressure. It will be helpful to predict the risks of cardiovascular diseases in adolescents.
