  • The purpose of this study was to investigate the differences in anthropometric, hematologic, and lipidologic data between normocholesterolemia and hypercholesterolemia and influencing factors in hypercholesterolemia in middle-aged men in Kwang-ju. 179 middle-aged men were involved. Anthropometric data(body weight, height, body circumferences and skinfold thickness) and hematologic data(blood pressure, fasting blood glucose, albumin and hemoglobin) were measured. Bleed lipid profile(total cholesterol, tr- iglyceride, phospholipid, HDI-cholesterol, LDL-cholesterol and VLDL-cholesterol) were analyzed. To determined using questionnaire. The subjects were classified as hypercholesterolemic based on The Guideline for Korean Hyperlipidemia. body mass index, systolic blood pressure, waist and hip circumference, and triceps, subcostal, abdomen, subscapular and suprailliac skinfold thicknesses of the hypercholesterolemic group were significantly higher than in the normocholesterolemic group. The concentrat- ion of cholesterol, triglyceride, phospholipod. HDL-cholesterol, LDL-cholesterol and VLDL -cholesterol of the hypercholesterolemic group were significantly higher than normocholesterolemic group. The concentration of cholesterol has a significantly positive correlation with body mass index, diastolic blood pressure, waist circumference, waist/thigh ratio and skinfold thickness(triceps, subcostal, abdomen, and supraillic skin- fold thickness). The general tendency of socioeconomec status, frequencyu of meat intake, smoking amounts and duration and duration and drinking frequencies and amount were higher in the hypercholesteolemic group but not significant. In conclusion, hypercholesterolemia in middle-aged men was closely correlated with upper body fat obesity and most of them had an accompanied high triglyceride level tendency.

  • The x-ray PIV method was improved for measuring quantitative velocity fields of real blood flows using a coherent synchrotron x-ray source. Without using any contrast media or seeding particles, this method can visualize flow pattern of blood by enhancing the phase-contrast and interference characteristics of blood cells based on a synchrotron x-ray imaging mechanism. The enhanced x-ray images were achieved by optimizing the sample-to-scintillator distance, the sample thickness, and hematocrit. The quantitative velocity fields of blood flows inside opaque tubes were obtained by applying a 2-frame PIV algorithm to the x-ray images of the blood flows. The measured velocity field data show typical features of blood flows such as the yield stress effect. The non-Newtonian flow characteristics of blood flows were analyzed using the x-ray PIV method and the experimental results were compared with hemodynamic models.

  • 동맥경화는 혈관이 좁아지면서 탄력을 잃어 혈액 순환 장애가 발생하는 질병으로, 최근 증가하는 심혈관 및 뇌혈관 질환의 잠재적 원인이 된다. 경동맥초음파 검사는 동맥경화 정도를 평가하여 심혈관 및 뇌혈관 질환의 예측인자로 사용되고 있다. 이에 본 논문은 경동맥초음파 검사에서 내중막 두께 증가와 여러 임상변수들 간 상관성을 알아보고자 하였다. 경동맥초음파검사 소견을 가지고 있는 환자를 대상으로 경미한 내중막 두께 비후, 경화반, 유의한 협착 3단계로 분류하였다. 경동맥의 동맥경화 정도와 신체적 특성(성별, 연령, 신체질량지수법, 혈압), 혈액검사(총콜레스테롤, 중성지방, 고밀도지단백질, 저밀도지방단백질, 크레아틴포스포키나제, 공복혈당)와 동맥경화도 검사에서 계측된 CAVI(Carotid Ankle Vascular Index : 혈관연령) 데이터를 수집하였다. 경동맥 내중막 두께는 고혈압, 고지혈증, BMI 등의 변수와 상관관계가 있었으며, 또한 CAVI가 증가될수록 심혈관계 질환의 위험요인과 상관관계가 있음을 확인하였다.

  • This study evaluates a cleaning method to maintain and minimize the change of blood soil for the selective removal of stains from textiles with historical significance and special meaning. Cotton and silk fabrics were soiled with blood, aged artificially and then washed by wet cleaning or dry cleaning (water, nonionic surfactant; Triton, natural surfactant; saponin, organic solvent; n-Decane). The washed fabrics were stored at room temperature for four years. The change of the blood soil was evaluated by SEM, weight, thickness, and color differences. Subsequently, the shape and the amount of blood adsorption on the fabric varied depending on fiber type and fabric structure characteristics; in addition, long term storage affected changes to blood soil. It was difficult to remove artificially aged blood soil from fabrics by wet or dry cleaning. However, the changes of the blood soil by these cleanings can be explained by the changes on SEM, weight, thickness and fabric color. The changes (especially color) showed over time. Wet cleaning showed that the changes of those factors were slightly lower than those by dry cleaning.

  • To evaluate training effect, aerobic dance was performed by eight female collegestudents for 8 weeks. Body composition, cardiopulmonary function at rest and during maximal exercise, blood cholesterol concentration at rest were determined before and after 8weeks of aerobic dance training. Maximal exercise was performed on the treadmill according of Bruce protocol. Pre to post training differences were evaluated. The results obtained were as follows : 1. After the training, skinfold thickness and total body fat decreased significantly(p<0.1) while lean body mass increased with significance (p<0.1). 2. Heart rate and arterial blood pressure at rest decreased without sinificance after the training. 3. As a result of training, forced vital capacity and forced expiratory volume for a second increased significantly (p<0.01, p<0.1). 4. After the training period, heart rate at 3, 6, and 9 min. during treadmill exercise was significantly lower than those of pretraining (p<0.05). 5. After the training, systolic and diastolic blood pressure at 6 and 9 min during the exercise was significantly lower than those of pretraining (p<0.025, p<0.1). 6. After the training, oxygen uptake at 3 and 6 min during the exercise was significantly greater than those of pretraining (p<0.05). 7. As a result of training, the maximal oxygen uptake increased significantly during the exercise (p<0.1). 8. After the training, expired air volume for a minute at 3 and 6 min during the exercise was signigicantly grerter than those of pretraining (p<0.1). 9. After the training, repiratory quotient during the exercise was lower than pretaining without significance. 10. After the training, blood HDL -cholesterol concentration incereased with significance, (p<0.1) blood total cholesterol and triglycerids concentration decreasedsignificantly (p<0.1). From these results, it may be concluded that 8 week aerobic dance training reduces skinfold thickness and body fat contents, improves the cardiopulmonary function and tissue oxygen utilization, reduces blood cholesterol and triglyceride concentration and brings about the increase of blood HDL-cholesterol concentriation.

  • To investigate dietary habits and health and nutritional status of the elderly with cerebrovascular disease(CVD), 31 hospitalized patients and 28 old people who had experienced stroke and were living at home were interviewed for the dietary habits and drinking and smoking habits. Their blood pressure and triceps skinfold thickness were measured and biochemical assessment of blood samples were conducted. The results were compared with those from 30 healthy elderly. Ca Index reflecting ca intake and intake of dietary fiber were significantly lower in the patient elderly groups than in the healthy elderly. Cholesterol intakes were not significantly different among the groups. Although salt intakes were almost similar among the groups, patient elderly tended to like salty taste as compared to the healthy elderly. Systolic and diastolic blood pressures of the patient elderly were significantly higher than those of the healthy elderly. Triceps skinfold thickness and serum total protein and albumin were significantly lower in patient groups than the healthy elderly. Serum cholesterol and hemoglobin concentrations were not different among groups. Among the above variables only Ca index was inversely correlated with blood pressure significantly.

  • Ssireum, the traditional Korean sport, is very popular at both amateur and professional levels. Ssireum players are prone to be obese which related to the chronic disease in their later life. The purpose of the study was to compare the anthropometric measurements, quality of diet, and blood parameters of Ssireum players with those of subjects who were matched body mass index, gender and age. Participants in the 3 groups, Ssireum players (SP, n=15), regular moderate exerciser (RME, n=15, >3 times /wk, >20 min/time) and intermittent light exerciser (ILE, n=14) groups. Anthropometric measurements included height, weight, fat mass (by Dual energy X-ray absorptiometry), lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), dietary variety score (DVS). Blood levels of lipids, leptin and insulin were analyzed. As a results lean body mass and mid-arm circumference were significantly higher in Ssireum players than those of other groups (p<0.01). Total body fat, trunk fat, abdominal skin fold thickness and waist-hip ratio were significantly lower in SP group than those of other groups (p<0.01). DVS were higher however, dietary quality was low in Ssireum players than in other groups. There were no differences among the 3 groups in regard to blood total cholesterol, LDL-cholesterol and glucose levels however, leptin level was low in Ssireum players. These results indicate that Ssireum players had significantly higher lean body mess and lower body fat when these were compared with regular moderate exerciser and intermittent light exerciser. Blood leptin levels of Ssireum players were low but blood lipid profiles were not significantly different.
