  • It is now generally accepted that individuals at increased risk for cardiovascular disease may be identified by certain traits or habbits. The factors such as high blood pressure, elevated blood cholestrol, age, sex and obesity are associated with increseaed frequency of disease. The blood cholesterol level lowering will decrease cardiovascular disease risk. The regression of atherosclerosis can be achieved by lowering the level of circulating cholesterol. Those things are connected with the quantity and quality of protein, fats, carbohydrates, especially soluble and non-soluble fiber, magnesium and calcium. The lipoprotein and lipid metabolism are connected with the lipid transport. The factors on lipid absorption and blood serum lipid pattern of human are exist. The factors have a variety of materials with different chemical and physical properties. The soluble fiber diet make a low blood and liver lipids. Many kind of soluble fiber results in a lowering of blood cholesterol and triglyceride levels. The cholesterol lowering effects of dietery fiber may be a results of alterations of in intestinal handling of fats, hepatic metabolism of fatty acid or triglyceride acid metabolism of lipoprotein. It is investigated that the high density lipoprotein (HDL) is inversely related to coronary artery disease. It has been postulated that HDL may be an important factor in cholesterol efflux from the tissues, therby reducing the amount of cholesterol deposited there. Alternatively, the HDL may pick up cholestyl ester and phospholipid during normal VLDL lipolysis in the plasma. The HDL levels are relatively insensitive to diet. At present time, the cause-and -diet effect of HDL's inverse relation to CHD remains unclear.

  • This study was performed to determine the risk factors associated with increased body mass index (BMI) in 672 heavy industry men workers. Subjects were examined in March, 2010 to September, 2010 in Gyeongnam province. Height, weight, systolic blood pressure, and diastolic blood pressure were measured. And fasting blood glucose, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride levels were measured by Olympus AU 680, and their BMIs calculated. Age, smoking statue, and alcohol drinking of the workers were surveyed by questionnairs. The mean total cholesterol levels were $190.06{\pm}36.62mg/dL$, HDL-cholesterol $53.65{\pm}11.92mg/dL$, LDL-cholesterol $104.28{\pm}30.31mg/dL$, triglyceride $151.11{\pm}99.53mg/dL$, and fasting blood glucose $96.92{\pm}19.53mg/dL$. Mean systolic blood pressure was $126.08{\pm}13.78mmHg$, and diastolic blood pressure $71.88{\pm}10.45mmHg$. Subjects were categorized into two BMI groups, BMI ${\geq}23$ and BMI ${\leq}22.9$. The subjects with BMI of 23 or above had significantly higher levels of LDL-cholesterol, systolic blood pressure, and triglyceride, with lower levels of HDL-cholesterol. BMI showed the highest level at the age of thirties, increasing with age. BMI of smokers was higher than BMI of non-smokers, not showing a link between alcoholics and non alcoholics. In conclusion, age, systolic blood pressure, and HDL-cholesterol are mostly relevant to the increase of BMI in this study.

  • KJST is the oriental herbal medicine of hyperlipemia which consisted of a herb of 17. We induced hyperlipemia to Spontaneous Hypertensive Rat(SHR) and studied the treatment effect by KJST. Hyperlipidemia was induced by hyper-lipidemic diet fed for 4weeks. Total cholesterol, LDL-cholesterol, HDL-cholesterol, Triglyceride, Total bilirubin, Lactic dehydrogenase(LDH), Glucose and Total protein were measured on the serum after an oral administration of KJST. Total cholesterol, LDL-cholesterol, Glucose and LDH was significantly lower in the KJST treated animals, and HDL was significantly raised in the KJST treated animals. These results suggest that KJST is effective for the treatment of hyperlipidemia.

  • Low-Density Lipoprotein cholesterol (LDLC) is the most important marker for the treatment of hyperlipidemia in NCEP-ATP III(National Cholesterol Education Program-Adult Treatment Panel III) guideline. Therefore, LDL cholesterol is pathologically meaningful, accurate measurement should be a top priority. Currently, LDLC is directly measured in most cases, but, the estimate is still used in mass health examination or screening test. This study is about the comparison of LDL-Cholesterol direct measurement with the estimate using various formula (Friedewald: [LDL-F=TC-HDL-TG/5], Nakajima: [LDL-N=TC-HDL-TG/4], Hattori: [LDL-H =0.94TC-0.94HDL-0.19TG], Puavilai: [LDL-P=TC-HDL-TG/6], Carvalho: [LDL-C=3(TC-HDL)/4]) for calculating more accurate value. We analyzed total cholesterol (TC), try-glyceride (TG), high-density lipoprotein cholesterol (HDLC), and LDLC levels of 210 subjects between June and November in 2011. Until now, the Friedewald formula is the most commonly used estimate for the LDLC. When Friedewald formula was applied, the correlation coefficient (r) was 0.940, showing high correlation. But, the result of the direct method was significantly different, compared with those of the Friedewald formula in triglyceride levels ${\geq}400mg/dL$(p<0.05). There was the highest correlation when we used LDL-P formula(r=0.947) in triglyceride levels <400 mg/dl. Also there was the lowest mean difference regardless of triglyceride level. Therefore, the study showed that TG/6 is more precise means of calculation than TG/5. On the other hand, the calculation of LDL-Cholesterol was underestimated, compared with direct measurement. It is necessary to have more data and modified Friedewald formula should be used for the accurate calculation.

  • This experiment was undertaken to investigate and compare the effect of salt on the lipid composition in serm and liver of rats. The average body weight gains and food efficiency ratio were not affected by supplementation with salt in diet. Total cholesterol and free cholesterol levels in serum of all experimental diet group were slightly increased by supplementation with salt, while triglyceride levels were significantly increased. HDL-cholesterol levels of all salt supplementation groups were slightly lower than that of the control group, while LDL, VLDL-cholesterol levels of these groups were higher than that of the control group. The ratio of LDL, VLDL-cholesterol to HDL-cholesterol; so called, atheorgenic index, in serum of salt diet groups was slightly higher than that of the control groups. The ratio of LDL, VLDL-lipoprotein to HDL-lipoprotein in salt diet group were significantly higher than that of the control group. The weight of the liver was not affected by diet, but total cholesterol and triglyceride levels of the liver in salt diet groups were higher than that of the control group.

  • To examine the association of hypertension with cluster of obesity, abnormal glucose and dyslipidemia in Korean urban population, we conducted this cross-sectional study among 3027 men and 2127 women age 20-85 years who visited a prevention center between May 1991 and June 1995 for a multiphasic health check at St. Mary's Hospital, Seoul. By the self-administered questionnaire, the informations of educational attainments, monthly income, alcohol consumption, cigarette smoking, and physical excercise level were obtained. Height, weight, and blood pressure were measured by a trained nurse. The fasting blood sugar (FBS), total cholesterol, high density lipoprotein (HDL) cholesterol and triglyceride were tested by enzyme method. Low density lipoprotein (LDL) cholesterol was calculated by 'total cholesterol - HDL cholesterol - triglyceride/5'. For testing the differences of cardiovascular risk factors between hypertension and normotension group, 1-test and $\chi^2$-test were performed. For the age adjusted odds ratios of hypertension in persons with obesity, abnormal glucose, and dyslipidemia compared with normal, logistic regression was performed by using SAS pakageprograme. The results obtained were as follows: 1. Age, weight, body mass index(BMI), blood glucose, total cholesterol, LDL cholesterol, and triglyceride of hypertension group in men and women were significantly higher than normotension group, but height and HDL cholesterol of hypertension group only in women significantly lower than normotension group. The frequency of obesity $(BMI\geq25kg/m^2)$, abnormal glucose $(\geq\;120mg/dl)$, hypercholesterolemia $(\geq\;240mg/dl)$, lower HDL cholesterol (<45 mg/dl in women only), higher LDL cholesterol $(\geq\;160mg/dl)$, and hyper hypertriglyceridemia $(\geq\;250mg/dl)$ in hypertension group of men and women were significantly higher than normotension group. 2. Systolic and diastolic blood pressure were negatively correlated with hight, but positively with age, weight, BMI, total cholesterol, LDL cholesterol, and triglyceride in men and women. BMI was positively correlated with fasting blood sugar, total cholesterol, LDL cholesterol and triglyceride but negatively with HDL cholesterol. 3. The age adjusted odds ratios of hypertension were as follows in men and women : among persons who were obese compared with those nonobese, 2.53 (95% Confidence Intervals [C.I.] 2.08-3.07) and 2.22 (95%C.I. 1.71-2.87): among persons who were abnormal glucose compared with those normoglycemic, 1.43 (95%C.I 1.13-1.82) and 2.01 (95%C.I 1.36-2.94): and among persons who were dyslipidemia (hypercholesterolemia or lower HDL cholesterol or higher LDL cholesterol or hypertriglyceridemia) compared with those normal lipid, 1.59 (95%C.I 1.30-1.95) and 1.51 (95%C.I 1.16-1.96). After combined more than one risk factor, the odds ratios were increased. Among persons with cluster of obesity, abnormal glucose, and dyslipidemia, the odds ratio of hypertension was 2.25 (95%C.I 1.47-3.37) in men and 3.02 (95%C.I 1.71-5.30) in women. In conclusion, it was suggested that hypertension was associated with cluster of obesity, abnormal glucose, dyslipidemia in this Korean urban population.

  • The present studies were designed to compare the effects of dietary fat sources and levels on plasma and tissue cholesterol. Changes in plasma total cholesterol and HDL-cholesterol, cholesterol concentration in aortas, liver and intestines were determined in young rats fed diets providing dietary fat as corn-oil or butter and levels as 10%, 20% or 30% of calories respectively 1) Plasma total cholesterol and HDL-cholesterol levels were little sensitive to the modification of dietary fat sources and levels. 2) Dietary cholesterol increased the levels of plasma total cholesterol and this effect was accentuated by feeding butter. But dietary cholesterol did not increase the levels of HDL-cholesterol in the butter-fed groups, but decreased in the corn-oil-fed groups. 3) Liver cholesterol concentrations were significantly higher in rats fed diets of corn-oil than those fed diets of butter. On the contrary, cholesterol concentrations of intestines were significantly higher in the butter-fed groups than the corn-oil-fed groups. However, in aortas, no significant differences were found.
