In this study. the importance of body fat distribution as an indicator of metabolic aberrations in diabetics was'evaluated. Skinfold thicknesses at eight sites and circumferences at five sites and total body fat content were measured on 105 diabetics. 1) The waist/thigh girth ratio(WTR) was positively correlated(r=0.38-0.54) to plasma glucose levels during oral glucose loading in diabetic men alone. 2) There was no significant difference in serum total cholesterol of diabetics and nondiabetics. However, HDL-cholesterol was significantly lower(p : 0.000. in male and female) in diabetics(male : 36.31$\pm$ 16.98mg/dl, female: 37.89$\pm$14.67mg/dl) than nodiabetics(male 61.75$\pm$14.08mg/dl, female : 62.29$\pm$12.65mg/dl) and serum triglyceride was significantly higher(p=0.0212) in diabetic women(171.90$\pm$ 76.61mg/dl) than nondiabetic women(111.10$\pm$42.84mg/dl) . 3) In both sexes. anthropometric measurements that significantly correlated to serum triglyceride concentration were percentage of ideal body weight. body mass index(BMI) and waist circumference. Positive and significant correlations were found between serum cholestrol, and BMI(R: 0.31, 0.34) and waist circumference(r=0.29) in diabetic men. Moreover, skinfolds of trunk area(r=0.29~0.32) especially abdomen, were closely associated with serum lipids than other fat deposits. Increasing percentage of total body fat content was accompanied by progressively increasing serum triglyceride concentration(r=0.41) in dieabetic men. This study shows that knowledge of body fat localization may help identify risks of carbohydrate intolerance and hyperlipidemia in diabetics.

BACKGROUD/OBEJECTIVES: The mechanism of how black garlic effects lipid metabolism remains unsolved. Therefore, the objectives of this study were to determine the effects of black garlic on lipid profiles and the expression of related genes in rats fed a high fat diet. MATERIALS/METHODS: Thirty-two male Sqrague-Dawley rats aged 4 weeks were randomly divided into four groups (n=8) and fed the following diets for 5 weeks: normal food diet, (NF); a high-fat diet (HF); and a high-fat diet + 0.5% or 1.5% black garlic extract (HFBG0.5 or HFBG1.5). Body weights and blood biochemical parameters, including lipid profiles, and expressions of genes related to lipid metabolism were determined. RESULTS: Significant differences were observed in the final weights between the HFBG1.5 and HF groups. All blood biochemical parameters measured in the HFBG1.5 group showed significantly lower values than those in the HF group. Significant improvements of the plasama lipid profiles as well as fecal excretions of total lipids and triglyceride (TG) were also observed in the HFBG1.5 group, when compared to the HF diet group. There were significant differences in the levels of mRNA of sterol regulatory element binding protein-1c (SREBP-1c), acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), and glucose-6-phosphate dehydrogenase (G6PDH) in the HFBG1.5 group compared to the HF group. In addition, the hepatic expression of (HMG-CoA) reductase and Acyl-CoA cholesterol acyltransferase (ACAT) mRNA was also significantly lower than the HF group. CONCLUSIONS: Consumption of black garlic extract lowers SREBP-1C mRNA expression, which causes downregulation of lipid and cholestrol metahbolism. As a result, the blood levels of total lipids, TG, and cholesterol were decreased.

Cigarette smoking is a well known risk factor for cardiovascular disease and has negative effects on blood lipid and lipoprotein . Some of the associations between smoking and chronic disease can be attributed to the less healthful lifestyles of smokers. A large body of epidemiologic evidence suggests inverse relationships between ischemic heart disease and plasma vitamin C and E concentrations . Smokers have lower plasma concentrations of these vitamins than do nonsmokers. Smokers therefore need antioxidant vitamin supplementation. The purpose of this study was to investigate the effect vitamin supplementation on plasma lipid patterns in smoking college men. 24subjects were divided into 3 groups of which were the vitamin C supplementation group (n=8), the vitamin E supplementation group(n=8) and the vitamin C+E supplementation group(n=8). The vitamin C supplementation group consumed 500mg of ascorbic acid, the vitamin E supplementation group consumed 200IU of D-$\alpha$-tocopherol, and the vitamin C+E supplementation group consumed 500mg of ascorbic acid+ 200IU of D-$\alpha$-tocopherol for 4 weeks. We examined the plasma lipid patterns before and after the vitamins were supplemented. The results obtained were as follows ; In the vitamin C supplementation group, the concentration of total cholesterol decreased significantly and HDL-cholesterol increased significantly with the supplementation of vitamin. In the vitamin E and vitamin C+E supplementation groups, however, there were no significant differences observed with the supplementation of vitamin. Concentration of plasma LDL, triglyceride, free fatty acid were not significantly affected by the supplementation of vitamin in all groups. In terms of plasma fatty acid composition, the concentrations of saturated fatty acid were not significantly affected by the supplementation of vitamin in all groups. The concentrations of palmitoleic acid, arachidonic acid, and docosahexaenoic acid, however, significantly increased in the vitamin E supplementation group(p<0.05). The concentration of plasma linoleic acid significantly increased in the vitamin C+ E supplementation group)(p<0.05). The results of this study show that antioxidant vitamin supplementation in smokers has a tendency to decrease coronary heart disease risk in view of the plasma total cholestrol and HDL-cholesterol concentrations of the vitamin C supplementation group and fatty acid concentration of the vitamin E supplementation group.

Magnesium(Mg) plays an important role in lipid metabolism and Mg deficiency but Ca sufficiency Increases serum cholesterol and triglyceride. The relationships of serum Mg, Ca, Ca/Mg ratio with lipids was examined in 79 female college students in Choong-Nam area. Subjects were divided into underweight, normal and overweight groups according to their BMI. The average age, body weight, height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.62kg/$m^2$ respectively. Height was not different between groups. Serum cholesterol and LDL-cholesterol concentrations were significantly lower in the underweight group than other groups. BMI had positive correlations with LDL-cholesterol, atherogenic index (AI) and LDL-cholesterol/HDL-cholesterol ratio(LPH), and negative correlations with HDL-cholesterol/total cholesterol ratio. Serum minerals (serum Mg, Ca, Ca/Mg ratio) and serum lipid concentrations were not significantly different between groups. However, there was a tendency of increasing serum Mg level with increasing serum HDL-cholestrol, HDL-cholesterol/total cholesterol ratio and decreasing serum LDL-cholesterol, LPH, total cholesterol/HDL-cholesterol ratio(TPH) and AI. And there was a tendency of increasing serum Ca level with increasing serum HDL-cholesterol/total cholesterol ratio and decreasing serum triglyceride, LDL-cholesterol, LPH, TPH and AI. And there was a tendency of increasing serum Ca /Mg ratio level with decreasing triglyceride, serum LDL-cholesterol and TPH. This study was limited within serum levels of minerals (serum Mg, Ca and Ca/Mg ratio), serum lipids concerned with CHD, therefore I hope there will be wider efforts to consider about the dietary levels of minerals for presentation of the connection between dietary Mg, Ca and serum lipids.

This study was undertaken to elucidate the effect of DHA-rich fish oil (DHA-rich oil) added to different dietary fats on lipid metabolism. Rats were fed perilla oil, sesame oil and beef tallow with or without DHA-rich oil for 12 weeks. The weight gain was higher in groups with DHA-rich oil than that of groups without DHA-rich oil, with DHA-rich oil, while weight of epididymal fat pad was lower in perilla oil and beef tallow groups with DHA-rich oil. The contents of total lipid and triglyceride in plasma were not affected by dietary fat types, but that of total and HDL cholesterol in plasma were higher in sesame oil group than perilla oil and beef tallow groups without DHA-rich oil. The contents of total lipid, triglyceride, total cholesterol, HDL cholestrol and LDL cholesterol in plasma were decreased by DHL-rich oil addition. The contents of total lipid, total cholesterol and triglyceride in the liver were not affected by dietary fat type. The contents of total cholesterol and triglyceride in the liver were not affected by dietary fat type. The contents of total lipid and TG in liver were not affected by DHA-rich oil addition while hepatic cholesterol increased by DHA-rich oil addition. The activities of glucose 6-phosphate dehydrogenase and malic enzyme were highest in beef tallow group without DHA-rich oil and decreased by DHA-rich oil addition. Peroxisomal ${\beta}$-oxidation had an inverse relationship against the activities of lipogenic enzymes. In conclusion, dietary DHA-rich oil decreased fat accumulation and had hypolipidemic effect, especially in beef tallow group. Also groups with DHA-rich oil showed more hypolipidemic effect than perilla oil group. And DHA-rich oil addition to diets resulted in increasing dietary n-3/n-6 ratio. Therefore increase in n-3/n-6 ratio as well as dietary DHA were considered to be responsible for the hypolipidemic effect resulted from DHA-rich oil addition.

The primary objective of these studies was to screen the materials showing inhibitions of HMG-CoA reductase in vitro. The secondary objective was to determine the effect of garlic, lovastatin and copper on cholesterol concentrations in plasma. liver and brease muscle of pullets. In experiment 1, the degree of inhibition of the selective samples on HMG-CoA reductase activity was determined in vitro. The inhibition rate of water soluble garlic extracts, lovastatin and copper to HMG-coA reductase activity were 51.3%, 87.5%, and 82.0% respectively . In experiment 2, control diet (basal diet), garlic powder (3% in diet) , lovastatin (300mg/kg of diet) and copper(200mg/kg of diet) were fed to pullets in order to investigate the changes of cholesterol concentration in plasma and tissues. Plasma total cholesterol , and LDL-cholesterol were significantly reduced in pullets fed a diet containing 3 % garlic powder. However, coper significantly increased total cholesterol compared to controls and lovastatin did not affect plasma chholesterol concentration . Total cholesterol inlover and breast muscle inpullets were not affectedb y adding cholesterol lowering materials to the diets. The data suggests that it is not easy for HMG-CoA reductase inhibitors to reduce cholesterol levels in the body due to complication in cholestrol metabolism . However, garlic administration can lower the levels of plasma cholesterol in pullets.
