Hypercholesterolemia has been regarded as a major risk factor of coronary heart disease(CHD). CHD is increasing in recent years among Koreans due to westernization of lifestyle and dietary behaviors. In the United States, implementation of the National Cholesterol Education Program(NCEP) had resulted 40% decline in mortality from CHD. This study was designed to evaluate the effect of medical nutrition therapy on serum lipid levels and discuss the effective nutrition education contents. Thirty outpatients(Male 40%, female 60%) with hypercholesterolemia were educated by medical nutrition therapy(MNT) protocol. At first visit and after three months of MNT, we assessed serum lipid profile, body weight and surveyed general characteristics, lifestyle and food habits through questionnaire. After 12 weeks of MNT, there were significant reductions in serum cholesterol and low-density lipoprotein cholesterol(LDL-C). Foods habits and lifestyle were changed to the desirable patterns. These results indicate that lipid profile is improved by changes of dietary behaviors and lifestyle. Especially in case of obesity, cholesterol lowering effect of MNT was more powerful. Consequently, MNT is effective on reduction of serum lipids by behavior change in hypercholesterolemic patients.

This study investigated the correlation of the nutritional status of antioxidant vitamins and serum lipids and MDA levels in postmenopausal women. Data about general characteristics, dietary intakes and biochemical parameters, including serum lipids, MDA and antioxidant vitamins levels, were collected from 85 postmenopausal women. The subjects were classified into three groups according to their serum total cholesterol level: normocholesterolemia group (NC, < 200 mg/dL), moderate hypercholesterolemia group (MC, $200{\sim}239mg/dL$) and hypercholesterolemia group(HC, ${\geq}240mg/dL$). The results are as follows. 1) General characteristics and serum MDA levels were not significantly different among the three groups. 2) Daily nutrients intakes adjusted to energy intake were not significantly different among the three groups, and were compatible with dietary reference intakes (DRIs) for Koreans. 3) Dietary Vt. A, ${\beta}-carotene$, Vt. C and Vt. E intake were not significantly different among the groups, while Vt. E intake was positively related with serum TC (r=0.288, p<0.05) and triglyceride (r=0.341, p<0.001) levels. 4) Serum Vt. A level standardized by serum TC level was significantly low and serum Vt. E level was significantly high in the HC group. Serum Vt. E level was positively related with serum TC level (r=0.389, p<0.001). 5) Dietary Vt. E intake was negatively correlated to serum MDA level (r=-0.242 p<0.05). Serum Vt. C and Vt. E levels were also negatively correlated to serum MDA level (r=-0.312, p<0.001 and r=-0.299, p<0.05). When the correlation was analyzed only in the group with hypercholesterolemia, correlation coefficients between the antioxidant vitamin and serum MDA level were higher. We concluded that intakes of antioxidant vitamins can contribute to decreasing the risk of cardiovascular disease by decreasing the oxidative stress of body rather than by controlling serum lipid levels.

Purpose : We investigated the effects of horseback riding and horseback riding machine exercise on the serum lipid profile in elderly individuals. Methods : Our study included 30 healthy elderly individuals who were randomly assigned to 2 groups: the horseback riding and the horseback riding machine exercise group, with each group comprising 15 individuals. The riding exercise program was performed 25 times a week over 12 weeks. The repeated measures analysis of variance was used to determine changes in serum lipid profiles before and after exercise 6 and 12 weeks after exercise. Results : An intergroup comparison of blood tests showed that triglyceride, total cholesterol and low-density lipoprotein-C levels were decreased in both groups after 12 weeks of the riding exercise program. However, both groups showed an increase in high-density lipoprotein-C levels, although this difference was not statistically significant. Conclusion : Horseback riding and horseback riding machine exercise showed a positive effect on the serum lipid profile in elderly individuals.

The purpose of this study was to investigate the distribution patterns of serum triglyceride and cholesterol levels and the influence of environmental and dietary factors in 201 healthy male subjects. The subjects were found to be 53.7% for the normal, 15.4% for the TC, 17.4% for TG and 13.5% for TC.TG group, respectively. Among general characteristics, smoking significantly affected serum lipid levels of subjects (p < 0.05). Among anthropometric factors, body weight, BMI and PIBW significantly influenced the blood lipid patterns. Body weight of TG group was significantly higher than that of normal group (p < 0.05). BMI and PIBW of TG group and TC.TG group were significantly higher than those of normal group (p < 0.05) . In addition, diastolic blood pressure of TG group was significantly higher than that of normal group (p < 0.05). For the food intake, average intake of fruit was significantly higher in normal group than that of TG group (p < 0.05). For nutrient intake, calcium intake was significantly higher in TC group than those of normal and TC.TG group (p <0.05). Intakes of vitamin $B_2$ and C were significantly higher in TC group than those of in TG group (p < 0.05). Serum HDL-cholesterol level was negatively related to meat, poultry, and their products (p <0.05), but serum total cholesterol level positively related to animal lipids (p < 0.05). The results of this study suggest that it is crucial for maintaining adequate serum lipid levels to reduce smoking, blood pressure and to lose body weight. As far as food intake concerned, fruit intake was important in maintaining serum triglyceride level normal, while animal food intake affected serum total cholesterol level adversely.

This study was designed to investigate the obesity rate with anthropometric indices, nutritional status and serum lipid levels of 260 school children from 5th grade of elementry school residing in Puchon city. Obesity was defined as fat percentage that exceeds 25$\%$. The prevalence rate of obesity were 15.2$\%$ for male and 14.1$\%$ for female. Mean fat percentage, BMI and Rohrer indice of obese male were 30.3$\%$, 21.0 and 150.2 respectively and 28.0$\%$, 21.5 and 151.9 for obese female. Mean serum TG, apo-B of obese female was significantly lower than that of non-obese. Obese male did not show any difference in serum lipid levels. The proportion of students whose serum cholesterol levels exceed 170mg/dI, which is cutoff point of bordeline for coronary artery disease, was 12.0% for male and 15.6$\%$ for female. The major factors affecting nutritional status were the amount of living expense, existence of mother's job and the regularity of having breakfast. Children who's living expense more than 500 thousants Won showed lower intake of Iron, vitamin A, thiamin, niacin and ascorbic acid(p$\ll$0.05). Children who's mothers are having a job were observed with decreased height(p$\ll$0.05). Children having breakfast regularly showed increased BMI and Rohrer indice than those of children having breakfast often of never.

Streptozotocin(STZ)에 의해서 유도된 당뇨성 쥐에서 nicotinamide의 영향을 알아보기 위하여 혈중 당의농도, 지질함량 변동과 동맥경화 지표와의 상관관계를 관찰하였다. STZ 투여로서 혈중당의 농도가 증가되던 것이 nicotinamide의 전처리로 정상상태로 억제되었고 total lipid 및 triglyceride 함량에서도 STZ 투여로 증가되던 것이 nicotinamide 전처리로 억제되었으나 phospholipid 함량에는 별다른 영향이 없었다. 혈중 total cholesterol. VLDL, LDL-cholesterol 함량 및 동맥경화 지표는 STZ에 의해 증가되었으나 nicotinamide 전처리로 저지되었으며 HDL-cholesterol 함량에서는 STZ 투여에 의해 감소되던 것이 nicotinamide의 전처리로 회복되었다. 혈중 lipase의 활성은 STZ 투여로서 억제되던 것이 nicotinamide의 전처리로 회복되었다. s-ALT 및 s-AST의 활성은 STZ 투여군이나 nicotinamide 전처리 군에서나 별다른 영향이 없었다. 이상의 실험 결과에서 nicotinamide의 전처리는 STZ에 의하여 유도되는 당뇨병을 예방할 것이라는 사실은 다른 측면에서 뒷받침하는 것으로 본 연구에서는 당뇨성 고지혈증의 예방에 nicotinamide가 유용하게 응용될 수 있는 가능성을 제시하고 있다.

This study was carried out to investigate the supplementary effects of the rice germ oil compared with soy bean oil on lipid metabolism of non-insulin dependent diabetic mice. Forty diabetic KK mice were fed two kinds of experimental diets with 20% lipid from soy bean oil as a control(CO) and rice germ oil(RG) for 8 weeks, respectively. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in food and water intake, body weight gain and organs weights between experimental groups. But the concentrations of serum total cholesterol and LDL-cholesterol were lower in RG group than in CO group. The hepatic total lipid and total cholesterol levels of RG group were significantly lower than those of CO group. The contents of total lipid, triglyceride and total cholesterol excreted in feces of RG group were higher than those of CO group. These results suggested that rice germ oil can reduce serum total cholesterol and LDL-cholesterol and hepatic total lipid concentration of non-insulin dependent diabetic mice compared with soybean oil due to increasing fecal lipid excretion. But we need to investigate the hypolipidemic effect of this oil by supplementary level and period.

This study was performed to investigate the effects of isolated soyprotein and salt (NaCl) restriction on the serum lipid and the kidney functions of streptozotocin-induced diabetic rats. Sprague-Dawley males of normal and streptozotocin-induced diabetic rats were raised for 6 weeds divided into 4 groups each according to protein sources and salt levels. The sources of protein were isolated soyprotein and casein. Salt levels tested were 0.1% (normal) and 0.01% (low). The results are summarized as fellows: kidney weight, blood glucose, hemoglobinAlc, GFR and urinary protein of diabetic groups were higher than those of normal groups. Isolated soyprotein lowered total lipids, triglycerides, and total cholesterol in serum and plasma angiotensin II concentration as well as alleviated kidney enlargement and GFR in diabetic rats. Salt restriction didn\\`t affect serum lipid level but decreased GFR and increased angiotensin If concentration. In conclusion, isolated soyprotein decreased serum lipids, plasma angiotensin II concentration, sidney enlargement and GFR, while salt restriction increased plasma angiotensin II concentration. The results suggest that isolated soyprotein and salt restriction seem to cause different effects on plasma angiotensin II concentration and that isolated soyprotein might be of value in the prevention of diabetic artherosclerosis and diabetic hypertension.

Purpose: This study was to examine the effects of the Danjeon Breathing Exercise Program on physical fitness, levels of serum lipid and physical symptom of people using public health center at Yangju city. Method: One group pretest-posttest design was utilized for this study. This study has been done from July 6 to September 28, 2005 and the subjects of the study were 28 persons. Danjeon breathing exercise was carried out for 60 minutes a day, 3 times a week for 12 weeks. Physical fitness was measured using the Health Management System developed by the Korea Physical Science Institution. Serum lipid level was measured in public health center at Yangju city. Questions of physical symptom (35 items) were chosen from Cornell Medical Index. The collected data were processed by using the SPSS PC program and analyzed by using Wilcoxon Signed Rank Test. Result: 1. The scores of back strength, flexibility and balance of post-test were more increased after Danjeon breathing exercise than those of pre-test. But the score of muscular endurance of post-test was not significantly increased. 2. The degrees of total cholesterol, LDL-cholesterol and triglyceride of post-test were more decreased after Danjeon breathing exercise than those of pre-test. But the degree of HDL-cholesterol of post-test was not significantly increased in statistics. 3. The score of physical symptoms of post-test was not significantly decreased in statistics after Danjeon breathing exercise than that of pre-test. Conclusion: It is concluded that the Danjeon Breathing Exercise Program could increase the physical fitness and decrease levels of serum lipid. So Danjeon breathing exercise could be utilized to promote physical fittness and to decrease level of serun lipids.
