  • LDL-콜레스테롤(LDL-C)은 심뇌혈관질환의 주된 교정 가능한 위험인자로서, 정확한 측정값을 임상에 적용하는 것이 중요하다. 하지만 LDL-C의 측정은 실제 측정이 아닌 Friedewald 공식에 의한 계산방법이 널리 이용되고 있다. 본 연구의 목적은 LDL-C의 Friedewald-추정값과 실측값을 비교하고, 두 방법의 LDL-C 위험수준 분류 일치도를 평가하는 것이다. 표본은 국민건강영양조사 2개년(2009년과 2010년)의 공개된 자료에서 추출되었고, 혈액 검사에서 총 콜레스테롤, HDL-콜레스테롤, 직접 측정한 LDL-C, 그리고 중성지방 중 어느 한 결측치도 없는 4,319명을 연구대상으로 하였다. 중성지방 400 mg/dL 미만일 때, Friedewald-추정값과 실측값은 높은 상관관계를 보였고 (r = 0.958, p < 0.001), 위험수준 분류 일치 백분율은 82.7%이었다. 중성지방 수준이 높을수록, 일치 백분율은 낮았다. 중성지방 수준 150 mg/dL 미만, 150-200 mg/dL, 그리고 200-399 mg/dL일 때, 일치 백분율은 각각 85.4%, 78.2%, 그리고 71.4%이었다. Friedewald 공식은 중성지방 농도 150 mg/dL 미만에서는 LDL-C를 과대평가하는 반면, 중성지방 농도 150 mg/dL 이상에서는 과소평가하는 경향이 있었다. 이에 따라 LDL-C 위험수준 분류에 있어 그 범주가 과대평가된 사람은 382명 (9.1%)인 반면, 과소평가된 사람은 348명 (8.3%)이었다. 이러한 결과는 Friedewald-추정값의 LDL-C 과소평가뿐만 아니라, 과대평가도 심각한 문제일 수 있음을 제시한다.

  • Object : This study was carried out to investigate the correlation between homocysteine and serum lipids which are known risk factors of stroke. Methods : The subjects were a total of 60 patients divided into a control group (n =30) and a sample group (n =30). The control group was normal homocysteine level without clinical symptoms, and the sample group was high homocysteine level with headache, dizziness, hypertension and so on. clinical symptoms, Each group was measured and compared for serum homocysteine, total cholesterol, triglyceride(TG), low density lipoprotein(LDL), and high density lipoprotein(HDL). Results : Total cholesterol, TG, and LDL were significantly increased and HDL was significantly decreased in the sample group. which was a high homocysteine level group compared with the control group, which was a normal homocysteine level group. Conclusion : In these results. it was suggested that increase of homocysteine leads to increase of serum total cholesterol, TG, LDL, but causes decrease of HDL. It seemed that risk of stroke is more at high homocysteine level than normal.

  • In order to independently examine the effects of long-chain saturated fatty acids and dietary cholesterol levels on plasma and hepatic cholesterol concentrations, six different diets were fed to male Mongolian gerbils (14 gerbils pes grcup) for an 8-week period. Purified diets contained 36% energy as fat (each saturated fatty acid tested comprised about 20% of the total fat energy) and 0.06% (w/w) cholesterol, corresponding to typical human consumption patterns in Western diets. Fat blends were formulated with natural fat sources. To determine the effects of different saturated fatty acids on plasma and liver cholesterol levels, four of the six diets contained constant levels of all nutrients except for the amounts of lauric acid (12 0), myristic acid (14 : 0), palmitic acid (16 0), and stearic acid (18 : 0). Dietary cholesterol effects were tested using 16 : 0-enriched diets containing 0, 0.006, and 0.06% (w/w) cholesterol. None of the plasma lipids were influenced by fatty acid treatment, including triglycerides, plasma total-, VLDL+LDL-, and HDL-cholesterol. However, hepatic esterified cholesterol concentrations were increased in the palmitic and stearic arid diet groups compared to the lauric and myristic acid diet group. The molar ratios of hepatic EC/FC were the highest in the palmitic acid diet (12.2 $\pm$0.6) and the lowest in the myristic acid diet (6.4$\pm$0.2). Dietary cholesterol significantly (p<0.001) increased the plasma total cholesterol which was due to the increase of both HDL-and VLDL+LDL-cholesterol. In the absence of dietary cholesterol and compared to other species, the gerbil exhibited a high molar ratio of hepatic EC/FC, which was funker elevated by dietary cholesterol feeding (0.06%). The results from this study indicate that hepatic cholesterol concentrations are sensitive to both low levels of dietary cholesterol and saturated fatty acid chain length and also, that plasma cholesterol concentrations are sensitive to low levels of dietary cholesterol .

  • Objectives : The protective effect of Vasopurus, a mixture of three medicinal plants, on atherosclerosis induced by dietary cholesterol in low density lipid (LDL) receptor deficient mice was studied. Methods : Experimental groups were divided into three groups of six animals each; a normal group (N); a high cholesterol group (HC), a high cholesterol plus Vasopurus group (HCVA). The experimental groups were fed for 6 months. Results : Vasopurus supplementation significantly lowered plasma total cholesterol and LDL cholesterol conc entrations compared with the high.cholesterol (HC) diet group. In addition, supplementation with Vasopurus significantly increased fecal cholesterol contents compared to mice fed a HC diet. Mice whose diet was supplemented by Vasopurus showed considerably fewer atherosclerotic plagues in the aortic values of heart and aortas compared to mice receiving the HC diet. Conclusions : These results indicate that Vasopurus has efficacy in anti.atherosclerosis medication.

  • The present study was designed to investigate the serum cholesterol lowering effect oj the phytosterol derivative (LPSS) on high cholesterol (HC) diet-induced hypercholesterolemia in male weaning Sprague-Dawley (SD) rats. Rats were fed with HC diet containing 1 % cholesterol and 0.5% cholic acid for 1 week. After 1 week, the LPSS oil suspension (0.32 g/kg B. W.) was orally administered to the rats fed with either basal diet or HC diet groups for 7 days. In addition, the LPSS powder (0.14%) mixed with basal diet or HC diet was Jed to the rats for 7 days. Serum total cholesterol and LDL-cholesterol contents were not altered by administration of the LPSS oil suspension with basal diet. However, they were significantly decreased by administration of the LPSS oil suspension with HC diet at day 14. Also, they were significantly decreased by the LPSS powder mixed with basal diet or HC diet at day 9, 11, 14. HDL-cholesterol contents were not altered by the LPSS oil suspension or LPSS powder. These results indicated that the phytosterol derivative(LPSS) might decrease serum total cholesterol and LDL-cholesterol contents in rats.

  • This experimental study was designed to investigate the inhibitory effects of Sojihwangamibang on hyperlipidemia in rats induced by high cholesterol diet diet. Sprague- Dawley rats were divided into normal group, control group, SJB treated group. Obese rats were induced by high cholesterol diet treatment for 6 weeks including a oral administration of SJB for 4 weeks. In SJB group, serum total cholesterol, LDL cholesterol, triglyceride and glucose were significantly decreased, and HDL cholesterol was significantly increased compared with untreated control group. In SJB group, HMG-CoA and ACAT concentration of hepatic homogenate were significantly decreased compared with untreated control group. These results provide experimental evidence that SJB, applied currently in the clinical practice, appears to be effective for down-regulating risk factors of hyperlipidemia, and thus may be used as an objective information for the development of therapeutic agents.

  • The effects of the Rhynchosia nulubilis extracts on serum lipid concentrations were evaluated in rats. Forty-two male Sprague-Dawley rats weighing $100{\pm}10g$ were divided into six groups and fed high fat and high cholesterol diets for four weeks. Experimental groups were administered with following diets; basal fat diet(control) and basal and high fat diets with 1% cholesterol and Rhynchosia nulubilis extract(40mg/kg, 400mg/kg and 4000mg/kg). The concentrations of serum triglyceride in rats fed the Rhynchosis mulubilis extract, high fat, 1% cholesterol, and RN-HFC(-40, -400, -4000mg/kg) groups were lower than those in other groups. The concentrations of total cholesterol in the RN-HFC (-40, -400, -4000mg/kg) groups were lower than those in fat diet groups. The concentrations of HDL-cholesterol in serum of the RN-HFC(-40, -400, 4000mg/kg) groups were significantly higer than those of other groups. The levels of LDL-cholesterol in serum of the RN-HFC(-40, -400, -4000mg/kg) groups were tended to be lower than those of other groups. These results suggest that Rhynchosia nulubilis extract may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

  • The purpose of this study was to investigate zinc and copper metabolism and risk factors of chronic diseases in 20 normal adults women. The daily intake, excretions in urine and feces, and serum levels of zinc and copper were determined by 24-hr food records and chemical analysis. The results were summarized as follows. mean age, body weight and BMI were 22.88 years, 54.65kg and 21.28kg/$m^2$ respectively. Mean daily intakes of energy and protein were 1578.84㎉(79% of RDA) and 52.05g (87% of RDA). The zinc and copper intake, excrestion in urine and feces were 7093.23$\mu\textrm{g}$(59% of RDA/2093.87$\mu\textrm{g}$, 203.50$\mu\textrm{g}$/39.87$\mu\textrm{g}$ and 3416.41$\mu\textrm{g}$/857.62$\mu\textrm{g}$, respectively. The serum levels of fasting glucose, insulin, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, zinc and copper were 76.60mg/㎗, 15.66IU/㎗, 160.30mg/㎗, 50.95mg/㎗, 89.80mg/㎗, 89.79mg/㎗, 95.65$\mu\textrm{g}$/㎗ and 73.28$\mu\textrm{g}$/㎗ respectively. Dietary ratio of Zn to Cu was shown to have significant positive correlations with serum insulin, total cholesterol, LDL-cholesterol. The urinary ratio of Zn to Cu was shown to have significant positive correlations with triglyceride. The serum copper level was shown to have significant negative correlations with serum total cholesterol and LDL-cholesterol. In summary, Zn consumption of adult women in their normal diet does not meet the Zn requirement for Koreans. Also, intakes of Zn and Cu may effect the glucose metabolism and cardiovascular diseases. Therefore, to increase the Zn intake and to maintain an appropriate intake ratio of Zn to Cu, nutrition education needs to be implemented.

  • This cross-sectional study was conducted to describe the changes of plasma cardiovascular disease(CVD) risk factors in Korea. Overnight fasting plasma levels of total cholesterol, high density lipoprotein(HDL)-cholesterol, triacylglycerol and glucose were analyzed. Blood pressure and anthropometric data were also measured. Health practice factors such as smoking status, alcohol consumption and frequency fo exercise were evaluated by a self-administered questionnaire. Questions regarding dietary habits and food preferences were also asked. Seventy eight percent of the subjects had more than one CVD risk factor. Plasma total cholesterol, triacylglycerol, and fasting blood glucose were significantly increased according to the subjects body mass index$(kg/m^2$, BMI), whereas HDL-cholesterol, low density lipoprotein(LDL)-cholesterol and blood pressure showed no significant differences with BMI. Current smokers had significantly high plasma total cholesterol, LDL-cholesterol and triacylglycerol levels. Alcohol consumption significantly increased plasma total cholesterol and fasting blood sugar, but regular exercise had no effects on the plasma CVD risk factors. Overeating and frequency of fast food consumption were positively correlated with the CVD risk score, whereas intake of grains, meats and vegetables were negatively correlated with that score. A stepwise multiple regression analysis was performed to examine the effects of specific dietary factors on plasma lipid levels. For plasma total cholesterol level, the frequency of fast food intake explained 8% of the variance, followed by habitual overeating, frequency of grain intake and high cholesterol food intake(Model $R^2$=22.4%). For plasma triacylglycerol level, preference of oily foods accounted for 7.5% of the variance, followed by eating breakfast, preference of fruit and frequency of grain intake(Model $R^2$=22.0%). The findings suggest that intervention programs to reduce the risk of CVD should focus on health practice through reducing BMI, smoking cessation and moderate or no alcohol drinking. Moreover, desirable dietary habits such as eating breakfast, not overeating and reduced intake of fast food may improve CVD risk.
