  • This study was done to examine the correlations between weight, BMI and risk factors of coronary heart disease in men and women in their forties and fifties. The subjects were 412 adults. who had regular health examinations between January and December of 1996 at S-Hospital in Seoul. The data were analyzed using ANOVA, Scheffe test, and Pearson correlation coefficient. The results are as follows : 1. The men between 50 and 59 years of age had higher levels for BMI, weight, systolic blood pressure, diastolic blood pressure, total cholesterol. LDL-cholesterol, triglyceride, fasting blood sugar, plasminogen activator-1, and hemoglobin A,C than the group of women in their forties. Yet. HDL-cholesterol was lower than in the former group. 2. In the group of men in their forties, weight was significantly correlated to diastolic blood pressure(r=.22), LDL-cholesterol(r=.20), plasminogen activator-inhibitor-1(r=.35) HDL-cholesterol(r=-.19). Their BMI was significantly correlted to systolic blood pressure(r=.27), diastolic blood pressure (r=.33), total cholesterol(r=.23), LDL-cholesterol (r=.26), plasminogen activator-1(r=.36) and HDL-cholesterol(r=-.25). 3. As for the group of women in their forties weight was significantly correlated to systolic blood pressure(r=.20), diastolic blood pressure(r=.22), triglyceride(r=.32) , plasminogen activator inhibitor-1 (r=.30) and HDL-cholesterol(r= -.37). Their BMI was significantly correlated to diastolic blood pressure (r=.25) triglyceride(r=.47), plasminogen activator-1 (r=.35), fibrinogen(r=.27) and HDL-cholesterol(r=-.47). 4. In the group of men in their fifties. weight was significantly correlated to total cholesterol (r=32), LDL-cholesterol(r=.29). plasminogen activator inhibitor-1(r=.26). Their BMI was significantly correlated to systolic blood pressure(r=.24), diastolic blood pressure (r=.22), total cholesterol (r=.34), LDL-cholesterol (r=.32), and plasminogen activator-1(r=.25). 5. In the group of women in their fifties, weight was significantly correlated to diastolic blood pressure(r=.33), total cholesterol(r=.21), LDL-cholesterol(r=.20), plasminogen activator inhibitor-1 (r=.43) and HDL-cholesterol(r=-.21). Their BMI was significantly correlated to systolic blood pressure(r=.25), diastolic blood pressure(r=.40), total cholesterol(r=.24), LDL-cholesterol(r=.24), triglyceride(r=22), and HDL-cholesterol (r=-.30). The above findings indicate that the BMI was more predictive than weight as a risk factor for coronary artery disease for men and women in their forties and fifties.

  • This study was designed to investigate the hyperlipidemia-healing effect of liquid extract from Mageum-tang(麻芩湯), it was performed on the hyperlipidemia of rats induced by high cholesterol diet and Triton WR-1339. We prepared two types of hyperlipidemia model in rats induced by high cholesterol diet and Triton WR-1339. The amount of total cholesterol, HDL-cholesterol, LDL -cholesterol, triglyceride, phospholipid, free fatty acid, the activity of superoxide dismutase(SOD), and glutathione were measured. The liquid extract from Mageum-tang showed significant decreasing effects on total cholesterol, LDL- cholesterol, triglyceride, phospholipid, free fatty acid in the both model. And it showed significant increasing effects on HDL-cholesterol, the activity of SOD in both model and amount of glutathione in Triton WR-1339 model. These results suggest that liquid extract from Mageum-tang has healing efficacy on hyperlipidemia induced by high cholesterol diet and Triton WR-1339.

  • The Preventive effect of the saponin fraction of Panax ginseng C.A. Meyer against hyperchole- sterolemia was demonstrated by assaying the cholesterol and triacylglyceride level of the blood serum and liver of rats fed high-cholesterol diet with and/or without ginsenoside. To understand the mechanism of the preventive action of ginsenoside, ginsenoside effect on LDL receptor binding ability, cholesterol level, and cAMP level of Chinese hamster ovary (CHO) cells cultured under various conditions were examined. When LDL (20 $\mu$g/ml) was added to the culture medium for CHO cell culture, LDL receptor binding activity of the cell was suppressed down to 58% of that of normal group. Ginsenosides at 10--2% and 10-3% level (w/v) were shown to exert an appreciable stimulatory effect on CHO cell LDL receptor activity, which partially overcame the suppression due to the presence of LDL (20 $\mu\textrm{g}$/ml) in the medium. Ginsenosides also reduced the increased cholesterol level of test group almost to that of normal group, and it increased cAMP level, which was usually reduced to 55% of that of the normal group due to the presence of LDL in the medium. Comparison of Kd and Bmax value of CHO cells cultured under different conditions revealed that this stimulation was due not to the receptor's binding affinity but to its number. Addition of ginsenoside (10-2%) decreased the uptake of taurocholic acid as much as 20% at the actively transporting everted ileal sacs, but it failed to form a large mixed micelles with taurocholic acid, which was one of the proposed mechanisms by which ginsenoside inhibits bile acid reabsorption. From the above results, it seemed likely that ginsenoside prevented hypercholestrolemia by decreasing cholesterol level in cells thereby relieving the inhibition of LDL receptor synthesis by cholesterol and also by inhibiting bile acid reabsorption from the small intestine.

  • This study was performed to find and compare the characteristics of dietary factors and obesity indices on serum lipid profiles using 407 healthy adult males that had physical examinations conducted at the general hospital located in Suwon. The subjects were divided 56.3% for the normal group, 16.7% for TG, 14.5% for TC and 12.5% for TC TG group, respectively. When comparing the blood lipid profiles to normal group, TC group was high in both total cholesterol and LDL-cholesterol, TG group was high in triglyceride and low in HDL-cholesterol, TC TG group was high in triglyceride, total cholesterol, LDL-cholesterol and low in HDL-cholesterol. In comparison of blood lipid profiles with normal group, among anthropometric factors, body weigh, BMI (Body Mass Index) and WHR (Waist Hip Ratio) showed significant differences. TC group was high in both total cholesterol and LDL-cholesterol, and TG group was high in triglyceride and low in HDL-cholesterol. TC TG group was high in triglyceride, total cholesterol and LDL-cholesterol, and was low in HDL-cholesterol. Body weigh of TG group was significantly higher than that of normal group (p<0.05). BMI and WHR of TG group and TC TG group were significantly higher than those of normal group (p<0.05). Total cholesterol was mainly related to the intake of animal lipids and alcoholic beverage. Serum triglyceride levels were closely related with lipid intake and high BMI in this group. In TC TG group, BMI and WHR were high. As well, serum LDL-cholesterol was high and HDL-cholesterol was low which indicates TC TG group had the most undesirable blood lipid profiles. Therefore, it may be necessary to manage BMI and WHR to prevent hyperlipidemia and obesity for adult males in Suwon.

  • Engorgement of macrophages with cholesterol is the defining pathological characteristic of atherosclerotic plaques, the cause of most heart attacks and strokes. Activated human macrophages uptake low density lipoprotein (LDL) by the bulk-phase fluid, and aggregated LDL by patocytosis. After incorporation of LDL and aggregated LDL into macrophages, neutral cholesterol esterase is decreased and cholesterol efflux is also deceased, resulting that macrophages become foam cells.

  • We analyzed and compared the concentration of total cholesterol (CHOL), high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol and triglyceride (TG) in serum and the serum protein electrophoresis fractions of thyroid disease patients. In comparison with the average of reference, our data showed that the average concentration of CHOL, LDL cholesterol and TG in hyperthyroidism patients were decreased significantly, but HDL cholesterol was increased significantly. In hypothyroidism patients, CHOL, HDL cholesterol, LDL cholesterol and TG were all increased significantly. In comparison of the concentration of lipids in each patient to reference range, 28.3% of hyperthyroidism patients showed abnormally low level of total cholesterol. In the patients with hypothyroidism, the percentage of patients showed abnormally high level of CHOL, HDL cholesterol, LDL cholesterol and TG were 37.7%, 10%, 68.8% and 49.1%, respectively. In our studies of serum protein electrophoresis, the average of ${\alpha}_2$-globulin and $\gamma$-globulin in hyperthyroidism patients were increased and $\beta$-globulin was decreased significantly. In hypothyroidism patients, the average of $\gamma$-globulin was increased and $\beta$-globulin was decreased significantly. In comparison of protein fractions of each patient to reference range, 38.3% and 50.0% of hyperthyroidism patients showed abnormally high levels of ${\alpha}_2$-globulin and $\gamma$-globulin, but 73.3% of patients showed abnormally low level of $\beta$-globulin. In hypothyroidism patients, 70.4% of patients were abnormally decreased in $\beta$-globulin and 63.9% of patients were abnormally increased in $\gamma$-globulin. These data suggest that the concentrations of CHOL, HDL cholesterol, LDL cholesterol and TG are not critical data for clinical interpretation of hyperthyroidism, but the levels of them are useful for interpretation of hypothyroidism patients. Our results of serum protein electrophoresis suggest that the concentration of serum protein electrophoresis fractions can be useful to understand the thyroid disease.

  • Sprague Dawley rats(24 weeks of age) were divided and were given normal diet for 6 weeks, followed by normal diet and 2% cholesterol diet for 14 weeks. During these periods, 10 weeks’ exercises are performed after 4 weeks. And then we analyze the blood and adipose tissue by decapitating those rats. 1. Serum total cholesterol was enhenced by cholesterol diet, while aerobic exercise tended to reduce it. 2. Cholesterol diet slightly reduced serum HDL-C and LDL-c, where as aerobic exercise showed a tendency to decrease it. 3. Cholesterol diet slightly reduced phospholipid and triglyceride, but aerobic exercise showed a tendency to increase them. 4. Aerobic exercise significantly decreased adipose tissue in normal diet rats and tended to reduce it in cholesterol-dietary rats. These results suggest that aerobic exercise decrease serum total cholesterol and LDL-C, and as a result can prevent atherosclerosis.

  • The principal objective of this study was to assess the effects of chitosan oligosaccharide supplementation on the improvement of blood glucose, lipid components and enzyme activities in the serum of streptozotocin(STZ, 55 mg/kg B.W., I.P. injection)-induced hyperglycemic rats fed on experimental diets for 5 weeks. The concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglycerides(TG) and phospholipids(PL) in serum were remarkably higher in the hyperglycemic group(group BSW) and STZ(I.P.)+chitosan oligosaccharide supplementation group(group ECW) than those in the control group(group BW, basal diet+water). However the concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, tree cholesterol, cholesteryl ester ratio, TG and PL in serum were lower in the ECW group than in the BSW group, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the ECW group were higher than in the BSW group. The activities of alkaline phosphatase(ALP) and aminotransferase(AST, ALT) in serum were lower in the ECW group than in the hyperglycemic BSW group. The results shown above suggested that chitosan oligosaccharide supplementation effectively improves blood glucose, lipid composition and enzyme activities in the sera of STZ-induced hyperglycemic rats.
