  • In order to investigate dietary risk factors for hypertension in th elderly, dietary intakes and dietary habits of 405 elderly subjects, aged 60-94, were assessed by the questionnaire, anthropometric measurement and a 24-hour dietary recall. The prevalence of definite (>95mmHg for diastolic or>160mmHg for systeolic blood pressue) and borderline(90-95mmHg for diastolic or 140-160mmHg for systolic blood pressure) hypertensive subjects 33.3% and 19.3%, respectively. The distribution of the subjects for Body Mass Index(BMI), waist-hip ratio, and alcohol consumption were significantly different among definite, borderline, and normal groups(p<0.05). The distribution of the subjects for smoking, exercise, and preference of salty food were not significantly different among definite, borderline, and normal groups(p>0.05). From the generalized logistic regression analysis of the risk factors for the hypertension, the subjects with over 27 of BMI had significantly higher risk of hypertension. Alcohol consumption and preference of salty food were significant risk factors of hypertension in the elderly. Dietary risk factors for the hypertension that had significant relationship to the hypertension were intakes of potassium, calcium, phosphate, sodium, vitamin B1, niacin, and folate. There was no significant difference of consumption frequencies of food and dish among definite, borderline, and normal groups(p>0.05). The amount of intakes for cereals and grain product, bean and their products, eggs were significantly different among definite, borderline, and normal groups(p<0.05). In summary, the amount of dietary intakes to hypertension in elderly population. Longitudinal studies for dietary risk factors on incidence of hypertension are needed in general population, especially in the elderly.

  • The aggregation characteristics of red blood cells (RBCs) are known as important factors in the microvascular flow system, and increased RBC aggregation has been observed in various pathological diseases, such as thrombosis and myocardial infarction. This paper describes a simple microfluidic device for measuring the RBC aggregation by integrating a microfluidic slit rheometry and laser-backscattering technique. While a decreasing-pressure mechanism was applied to the microfluidic rheometry, a syllectogram (the light intensity versus time) showed an initial increase and a peak caused by the high shear stress-induced disaggregation, immediately followed by a decrease in the light intensity due to RBC aggregation. The critical shear stress (CST) corresponding to the peak intensity was examined as a new index of the RBC aggregation characteristics. The CST of RBCs increased with increasing aggregation-dominating protein (fibrinogen) in the blood plasma. The essential feature of this design was the combination of the rheometric-optic characterization of RBC aggregation with a microfluidic chip, which may potentially allow cell aggregation measurements to be easily carried out in a clinical setting.

  • 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.

  • Recently, radionuclide angiocardiogram is one of the most common procedure for assessment of ventricular performance due to its distinctive advantages such as safety, accuracy, and ease of repeated studies. Also, measurement and comparison between pre and postoperative left ventricular ejection fraction [LVEF] are meaningful for assessing the severity of myocardial damage which occurred during open heart surgery and the status of myocardial recovery. We obtained pre and post operative LVEF using radionuclide angiocardiogram on 30 patients composed of atrial septal defect, ventricular septal defect, cyanotic congenital heart disease, and valvular heart disease who undergone the open heart surgery from March to august 1984. The study revealed that ventricular septal defect and mitral valvular heart disease showed 8.1% and 6.2% decreases of postoperative LVEF, respectively. But, there are little increases of postoperative LVEF in the atrial septal defect and cyanotic congenital heart disease. In ventricular septal defect, each group of Qp/Qs over 2.0 and systolic pulmonary artery pressure over 50mmHg showed significant 17% and 14.7% decreases of postoperative LVEF, respectively. Considering the duration of the aortic cross clamping times and closing methods of VSD, each group of duration over 30 min. and of patch closure showed 13.9% and 14.2% decreases of LVEF between pre and postoperative status respectively which was significant finding statistically.

  • This study classified subjects aged 30 to 64 into normal group, impaired fasting glucose group, and diabetes mellitus patient group based on data from the 6th period of the National Health and Nutrition Examination Survey (2013-2015). Skipping breakfast, lack of physical activity, inadequate sleep time, inadequate weight, excessive drinking, and current smoking are classified as a low health risk group when three or less items are present, and a high health risk group when three or more items are included. By classification, each item included in the physical measurement and biochemical analysis factors and health risk behavior factors was comparatively analyzed. As a result, in the normal group, impaired fasting glucose group, and diabetes group, the average age was higher in the group with high health risk factors than the group with low risk factors, and the male ratio was higher. Body mass index, waist circumference, blood pressure, triglyceride showed a significantly higher result. In the normal group, the fasting blood glucose level and total cholesterol level were also higher in group 2. Therefore, it is thought that it is necessary to control health risk behaviors through lifestyle changes in the normal group, fasting glucose disorder group, and diabetes group.

  • In an effort to elucidate the physiological characteristics in cardiopulmonary function, electromyogram(EMG), and blood chemistry in athletic high school students, an analysis of electrocardiogram(ECG) and EMG, pulmonary function test, venous blood gas analysis($Pvo_2$ and$Pvco_2$), and measurement of heart rate, blood pressure, respiratory rate, blood glucose and blood lactate were made for 16 to 19 year-old high school students who were divided into athletic (n=19) and non-athletic (n=20) group. The results obtained are summarized as follows. 1) ECG intervals in athletes were longer than in non-athletes, and the difference was significant in R-R, Q-T and T-P intervals. Resting heart rate in athletes was 56.3/min showing a bradycardia compared with 79.8/min in non-athletes. Amplitudes of R and T waves in lead $V_5$ were significantly higher than in non-athletes. 2) Pulmonary function parameters in athletes showed higher values than in non-athletes. Parameters which showed significant differences were FEV 0.5, PEF, FEF 25%, PIF and FEF $200{\sim}1.200\;ml. 3) Heart rate, blood pressure, and respiratory rate after exercise were significantly elevated from resting values. Heart rate and respiratory rate showed greater increase in non-athletes, while blood pressure showed greater increase in athletes. 4) $Pvo_2$ was lowered ana $Pvco_2$ was elevated after exercise, and there was no significant difference between two groups. 5) Blood glucose and lactate levels were elevated after exercise. The difference was significant in blood lactate, and was greater in non-athletes. 6) EMG amplitude was steadily increased with increasing load of exercise, and the increase was greater in athletes than in non-athletes.

  • The purpose of this study was to compare knowledge on hypertension and blood parameters through blood pressure control of hypertensive patients commuting to a public health center. Hypertensive subjects were classified according to their blood pressures into a well-controlled group (SBP<140 mmHg and DBP<90 mmHg, n=44) and an uncontrolled group ($SBP\geq140mmHg\;or\;DBP\geq90mmHg$, n=41). All subjects were interviewed for clinical characteristics, effort for health maintenance and knowledge on hypertension and nutrition. Biochemical measurement of blood urea nitrogen, creatinine, triglyceride, total cholesterol, HDL-cholesterol and fasting blood glucose (FBG) were obtained from subjects. The knowledge about hypertension and effort for health maintenance were not significantly different between the groups. However, the nutrition knowledge score of the well-controlled group was significantly higher (p<0.05) than that of the uncontrolled group. On the test of nutrition knowledge, 97.7% of the well-controlled group answered correctly to the item, 'Medication is an easy way to control blood pressure'. This result was significantly higher (p<0.05) than that of the uncontrolled group of whom 82.9% answered correctly. Participants in both groups had only a little understanding about the importance of a balanced diet. Blood parameters were in the normal range and there was not a significant difference between the groups. However total cholesterol, triglyceride and fasting blood glucose levels of the uncontrolled group were higher than those of the well-controlled group. Therefore, education programs about the continuous control of hypertension through careful monitoring, medication, and exercise are required. The uncontrolled group was especially in need of strengthening education. Also more effective nutrition education programs about low salt, high fiber, low cholesterol, and balanced diets are required for hypertensive patients commuting to public health center.
