Background: The purpose of this study was to evaluate the effectiveness and the level of self-management support on the Metabolic Syndrome Management Program at public health centers in Seoul metropolitan city. Methods: The effectiveness on the Metabolic Syndrome Management Program were analyzed using secondary data from 1,312 community residents who were receiving program. The level of self-management support on Metabolic Syndrome Management Program was evaluated using an 'Assessment of Primary Care Resources and Supports for Chronic Disease Self-Management' from four public health centers. Results: The effectiveness on the Metabolic Syndrome Management Program was showed that decreased smoking (p= 0.044) and drinking (p< 0.001), and increased healthy dietary habit (p< 0.001) in health behaviors. It was showed that decreased triglyceride (p= 0.002) and increased high-density lipoprotein cholesterol (p< 0.001) in clinical indicators. The level of self-management support on Metabolic Syndrome Management Program was 98.1 points and it meaned that implementation is done in an organized and consistent manner using a team approach. There was difference in the level of self-management support by public health centers (p= 0.003). Conclusion: The Metabolic Syndrome Management Program in public health centers was effective, and level of self-management support was done as organizational level, but patient input and mental health were insufficient.

The optimum conditions for the production of Lentinus edodes mycelia and it's hypoglycemic effect was studied. Optimum pH and temperature for the production of mycelia in shaken flask culture were 5 and $30^{\circ}C$, respectively, for 24 days cultivation. Culture period for maximum production of mycelia (8.13 g/l) in 5-l jar fermenter cultivation was shortened as much as 6 days compared to shaken flask culture. The mycelial dose of 5 % proved almost equally effective in lowering the plasma glucose, total cholesterol, and triglyceride level as much as 23.0, 20.7, and 27.1%, respectively. The values of alanine transaminase and aspartate transaminase were also estimated and exhibited a substantial reduction (29.6 and 34.3%, respectively) in activity after the administration of dried mycelia.

The purpose of this research was to examine the relationship between the plasma LDL particle size and blood lipid profile, dietary factors and anthropometric values (body mass index, waist circumference and waist/hip ratio). The subjects were 173 adults aged 23 to 81 years, selected from the Outpatient Clinic and Cardiovascular Department of the Seoul Municipal Hospital. Dietary data were obtained using a 3-day food record and analyzed using Korean and US nutrient databases. The subjects were divided into three groups by LDL particle size : type A (large buoyant LDL, > 25.5 nm, n=96), type I (Intermediate LDL,$25.2\leq-\leq25.5$ nm, n=18), and type B (small dense LDL, < 25.2 nm, n=59) groups. The type B group had higher age, waist circumference, and waist/hip ratio (WHR) than the type A and type I groups. Serum concentration of triglyceride, Apo B, LDL/HDL cholesterol ratio and atherogenic index were significantly higher in the type B group as compared to those in the other two groups. HDL cholesterol level and Apo A-I/Apo B ratio were significantly lower in the type B group than the other two groups. The plasma LDL particle size was highly correlated with triglyceride (r= -0.450), Apo B (r= -0.402) and HDL cholesterol (r= 0.418). However, there was no correlation between plasma LDL particle size and dietary intakes. This study showed that small dense LDL was an important biochemical risk factor that was associated with other risk factors.

This study done to investigate the hypocholesterolemic effect of ow dietary fiber in a high cholesterol diet in aspect of cholesterol absorption and excretion using Sprague Dawley rats. After feeding diets containing 0.5% cholesterol and 5% tangerine pulp, sea tangle or prickly pear cactus for four weeks, we measured the levels of plasma and liver cholesterol and triglyceride, fecal neutral sterols and fecal radioactivity after ingestion 14(sup)C-cholesterol. We also examined platelet aggregation and histological change in liver tissues in association of hypercholesterolemia. The liver to body weight ratio was significantly(p<0.01) lower in rats fed prickly pear cactus than in other groups. The levels of plasma total cholesterol, LDL-cholesterol and triglyceride were decreased significantly(p<0.01) in the prickly pear cactus group compared with the control, while there was no difference in the liver levels of total cholesterol and triglyceride among groups. Fecal corprostanol and cholesterol were significantly(p<0.01) higher groups of control and prickly pear cactus compared to the other two groups. Radioisotope excretion after ingestion of 14(sup)C-cholesterol was higher in the control group than in tangerine pulp group or sea tangle group, with the highest in prickly pear group. Radioisotope excretion was the highest during the 2nd and 3rd days in all groups. Hematocrit and platelet aggregation were decreased in all fiber groups compared to the control, but not statistically different. Microscopic examination showed that cholesterol diet cause a fat accumulation in the liver and prickly pear cactus decreased the fat accumulation. Result indicates that prickly pear cactus has hypocholesterolemic effect by decreasing absorption and increasing excretion of cholesterol, thereby protective effect on fatty liver. Control group fed diet containing high cholesterol and low fiber seems to have a self control system in cholesterol absorption and excretion preventing hypercholesterolemia.

This study was conducted to investigate the effects of caffeine on lipid and mineral content in the serum of rats given a caffeine free diet(FC), a low caffeine diet(LC), a medium caffeine diet(MC), a high caffeine diet(HC) or a super-high caffeine diet(SHC) for 5 weeks. Thirty male Sprague-Dawley rats(body weight, $110{\pm}0.3$ g) were blocked into 5 groups and fed diets with or without pure caffeine. Caffeine intake models showed a lower mean-weight gain, food intake and food efficiency in the high caffeine diet groups(MC, HC and SHC groups) than the groups receiving a caffeine free or low caffeine diet(FC and LC groups). Serum total lipid, total cholesterol and LDL-cholesterol levels decreased, but the serum HDL-cholesterol level increased according to the increase in caffeine intake. Serum total lipid, HDL-cholesterol and serum triglyceride were significantly lower in the HC and SHC groups than the FC group. All of the serum minerals decreased as caffeine intake increased. Serum iron, calcium, magnesium and phosphorus significantly decreased in the HC and SHC groups compared to the FC group. Caffeine intake was associated with less weight gain and reduced serum total cholesterol, triglyceride and total lipid. The results suggest that rats fed high amounts of caffeine may be susceptible to osteoporosis due to their low levels of calcium, magnesium and phosphorus.

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.

The current study was designed to assess the effects of emulsified sausage supplemented with ginseng saponin on lipid metabolism by applying a rat model. Four groups of 8 rats (5 wk old) were each allocated one of 4 treatments: basal feed (C), and basal feed with 20% sausage powder containing 0% (S0), 2% (S2) and 4% (S4) ginseng saponin. The experiment was conducted for 4 wk. The results did not differ among the treatments with different amounts of sausage (ST), but daily feed intake (p<0.01) and feed conversion (p<0.001) were significantly increased in STs compared to C. Both total serum cholesterol and triglyceride concentrations were significantly (p<0.001) reduced, by 45 and 46%, and 48 and 46%, in S2 and S4, respectively, compared to S0. In the liver, the total cholesterol level was dramatically (p<0.05) decreased according to increasing sausage powder levels. In particular, S4 showed approximately 14% reduction compared to S0 (p<0.05). Liver triglyceride content also showed a similar tendency, where S2 and S4 resulted in 7% and 31% reduction. With regard to fatty acid composition in the liver tissues, palmitic acid (16:0), oleic acid (18:1), eicosanoic acid (20:1), and eicosatrienoic acid (20:3) did not differ among the STs, whereas both linoleic acid (18:2) (p<0.01) and linolenic acid (18:3) (p<0.001) showed significant increases in S2 compared to S0. The current data demonstrated that emulsified sausages supplemented with ginseng saponin effectively reduce total cholesterol and triglyceride concentrations in the serum and liver, and increase unsaturated and essential fatty acid in the liver. These data collectively imply that the sausage improved the overall lipid profile in a rat model, and can be further generalized to the result that emulsified sausage can improve lipid metabolism depending on the products' formula.

This study was performed to investigate the effects of Korean native plant diets on lipid and cadmium (Cd) metabolisms and also antioxidative enzyme activities in rats. Seventy male Sprague-Dawley rats weighing 210.3$\pm$2.7g were blocked into ten groups according to body weight. Rats were raised for four weeks with diets containing 0 or 0.04%(w/w) cadmium chloride and 5%(w/w) plant powder-Ssook(Artemisia princeps var. orientalis HARA), Chamchwi(Aster scaber THUNB), Gomchwi(Lingularia fischeri TUBCZ). or Solbeerum (Portulaca oleracea LINNE). Food intake, weight gain, food efficiency ratio, and weights of liver, kidney, spleen and epididymal fat were significantly lower in Cd-exposed groups, food efficiency ratio, and weights of liver, kidney, spleen and epididymal fat were significanlty lower in Cd-exposed groups. Plasma total lipid level, liver total lipid, cholesterol and triglycerde concentrations, and fecal total lipid, cholesterol and triglyceride excretions were decreased by Cd administration. Total lipid and triglyceride concentration in plasma and liver were lower in Chamchwi groups together with increased fecal total lipid and triglyceride excretions. Cholesterol concentration in plasma and liver were lower in Gomchwi groups with increased fecal cholesterol excretions. Activities of red-blood-cell superoxide dismutase(SOD), and liver catalase, SOD and glutathione peroxidase (GSH-px) were decreased significantly by Cd administration. Thiobarbituric acid reactive substance(TBARS) concentrations of plasma and liver were increased by Cd administration. Thiobarbituric acid reactive substance(TBARS) concentration of plasma and liver were increased by Cd administration. Administration of plant diets decreased plasma and liver catalase, SOD and GSH-px activities in Cd-free diet groups and increased them in Cd-administered groups. Plasma and liver TBARS concentrations were decreased in animals fed plant diets, with Chamchwi showing the most effective antioxidative capacity. The concentration of Cd accumulated in blood and tissue decreased in Cd-exposed groups fed plant diets. Liver Cd concentration were lower in the Chamchwi and Gomchwi groups, and kidney Cd levels were lower in the Ssook and Chamchwi groups. Among them, Chamchwi was the most effective in Cd detoxification. In conclusion, Chamchwi and Gomchwi were effective in lowering tissue lipid levels, with Chamchwi having the greatest antioxidative and detoxifying effects.

This study was conducted to determine the effect of different fiber content of rice on blood levels of glucose insulin and triglyceride in normal subject. Ilpum and Suwon 464, which have different fiber content were used for the test. Two types of rice containing 50 g of carbohydrate were pressure-cooked and fed to ten healthy male volunteers after an overnight fast. After a meal, the 60-min blood glucose levels of Suwon 464 and Ilpum were 90.3$\pm$4.8 mg/dL and 111.6$\pm$2.7 mg/dL, respectively (p<0.01). And the 120-min blood insulin levels of Suwon 464 and IlPum were 2.9$\pm$0.8 mg/dL and 7.7$\pm$1.6 mg/dL, respectively (P<0.05). There was no significant difference in triglyceride level between two rice varieties. The calculated glycemic index (GI) was 64.5% for Suwon 464, suggesting that Suwon 464 high in fiber can be useful in low-GI diets.

The effects of taurine on plasma and liver cholesterol, erythrocyte ouabain sensitive Na efflux and platelet aggregation were examined in Sprague Dawley rats fed control or 0.5% cholesterol with 0.2% cholate diet. Plasma and liver levels of total cholesterol were increased significantly (p<0.05) in rats fed cholesterol diet compared to the control, and taurine significantly decreased the elevated plasma level of cholesterol in rats fed cholesterol diet (p<0.05). HDL-cholesterol was decreased in groups fed the cholesterol diet regardless of taurine supplementation and the difference between groups with and without cholesterol was significant (p<0.01). Plasma triglyceride was decreased and liver triglyceride was increased both significantly (p<0.05) in rats fed cholesterol compared to the control. Plasma and liver triglyceride in rats fed taurine was decreased significantly compared to the control (p<0.05). Intracellular Na tended to be lower in rats fed cholesterol or taurine and higher in rats fed cholesterol plus taurine compared to the control. Na efflux through Na-K ATPase and the passive leak of Na was somewhat reduced in rats fed cholesterol or taurine and was augmented in rats fed cholesterol plus taurine compared to the control, which showed a similar trend to the intracellular Na. Taurine supplementation caused a suppression of Na efflux in groups fed control diet and restored the suppressed Na efflux in groups fed cholesterol. Platelet aggregation was significantly decreased in the group fed taurine compared to the control (p<0.05) and the group fed cholesterol plus taurine was also a little lower in aggregation than the group fed cholesterol. Microscopic examination showed that taurine prevented fatty liver in rats fed cholesterol diet. Taurine known for stimulating Na-K ATPase in some cell types rather decreased erythrocyte ouabain sensitive Na-K ATPase in the present study. Taurine had hypolipidemic and hypocholesterolemic effects and inhibited platelet aggregation which may be favorable for prevention of cardiovascular diseases.
