The purpose of this study was to evaluate the possibility that administration of Bacillus polyfermenticus KJS-2 (BP2), Bacillus mojavensis KJS-3 (Moja3), and their mixtures could control serum lipid levels. We observed changes in the blood cell level, metabolic function evaluation, and blood lipid levels after two weeks of oral administration of these microbial strains to hyperlipidemia-induced rats. Measurements of major cell changes in the white blood cells (WBC) indicated no significant effects due to the administration of the microbial strains. Platelet (PLT) levels decreased by 18.4% in the Triton WR-1339-treated group (NCON) and recovered to the control (CON) group levels in the positive control (PCON) group and the microbial strain-administered groups (p<0.05). No functional changes were observed in red blood cells (RBC) by Triton WR-1339-induced hyperlipidemia. The blood AST, ALT, BUN, and creatinine levels did not indicated effects on liver and kidney function, and all rats administered the microbial mixture recovered. The blood lipid levels in the microbe-treated groups indicated reduced levels of triglyceride (TG) and total cholesterol (TC), and increased levels of serum HDL cholesterol. The HMG-CoA inhibition rate of 7-O-succinyl macrolactin A (SMA) produced by BP2 showed similar activity at a concentration of 1,000 times lower than that achieved with atorvastatin. The administration of the microbial strains to the Triton WR-1339-induced rat model of hyperlipidemia resulted in reduced weight gain without affecting the food and water intake. Thus, blood circulation can be improved by controlling serum lipid levels by the combined administration of the BP2 and Moja3 microbial strains.

This study was conducted to examine the effect of dietary iron levels on lipid metabolism, antioxidative and antithrombogenic capacities in 16-month-old rats. Thirty-two Sprague-Dawley male 16-month-old rats weighing 618 $\pm$ 6 g were raised for 10 days with medium-iron diet (35 ppm in diet) and blocked into 4 groups according to their body weights. One of groups was sacrificed to obtain initial data and the rest 3 groups were raised for 3 months with experimental diets containing different levels of iron (5 ppm, 35 ppm, and 350 ppm). Total lipid, triglyceride and total chole-sterol concentrations in plasma and liver, HDL-cholesterol concentration in plasma, fecal total lipid triglyceride and total cholesterol excretions, thiobarbituric acid reactive substances (TBARS) level in plasma LDL + VLDL (low density lipoprotein + very low density lipoprotein) fractions, blood-clotting time and eicosanoids levels in plasma were measured. The results are as follows: Plasma total lipid, triglyceride and total cholesterol concentrations, TBARS level in plasma LDL + VLDL fractions were increased and blood-clotting time tended to be shortened during 3 months of experimental period. Low (5 ppm) iron diet improved lipid metabolism via increasing HDL-cholesterol and fecal choles-terol excretion. High (350 ppm) iron diet decreased plasma total lipid, triglyceride and total cholesterol concentrations as compared to medium (35 ppm) iron diet and lowered body weight and epididymal fat pad weight. On the other hand, TBARS level in plasma LDL + VLDL fractions and blood-clotting time were increased with high iron diet. It is plausible that low iron diet improves lipid metabolism, antioxidative and antithrombogenic capacities in 16-month-old rats.

The effect of excess L-ascorbic acid(AsA) in blood, liver lipid levels and peroxidation status were investigate . Ten Sprague-Dawley male rats weighing 150-200g were fed 300mg AsA/100g body weight/day, mixed into ground chow diet, for 4 weeks. And another set of then rats were fed only chow diet as the control. Average body weight gain was slightly lowered by AsA feeding without food intake change. The AsA group showed higher AsA levels in plasma and liver than the control group. In addition, the AsA group showed a higher plasma TBARS value. Liver TBARS seemed to be elevated in the AsA, but not significantly. The hemolysis of red cells tended to increase with excess AsA, accompanied by a raised GSH-Px activity and lowered total GSH levels. Plasma HDL-Chol level was increased while the levels of total Chol, LDL-plus VLDL-Chol , and triglyceride were unchanged . Atherogenic index decreased. Hepatic TG levels were also decreased, but the total amount of Chol increased slightly . Platelet TXA$_2$ production was inhibited by excess AsA feeding. Above results indicafe that oral feeding of excess AsA may be beneficial in reducing the risk of atherosclerosis ; however such practice may be detrimental for tissue lipid peroxidation and weight gain.

The present study was carried out to evaluate the physiological effects of seaweed supplementation on blood glucose levels, lipid profile, and antioxidant enzyme activities in subjects with type 2 diabetes mellitus. Subjects were randomized into either a control group or a seaweed supplementation group. Pills with equal parts of dry powdered sea tangle and sea mustard were provided to the seaweed supplementation group three times a day for 4 weeks. Total daily consumption of seaweed was 48 g. We found that total dietary fiber intake was 2.5 times higher in subjects receiving seaweed supplementation than in the control group. Accordingly, fasting blood glucose levels (p<0.01) and 2-hour postprandial blood glucose measurements (p<0.05) were decreased significantly in those ingesting seaweed. Furthermore, the serum concentrations of triglycerides were decreased and high-density lipoprotein cholesterol was increased significantly in seaweed supplement group (p<0.05). However, the concentrations of total cholesterol and low-density lipoprotein cholesterol were not affected by seaweed supplementation. The level of thiobarbituric acid reactive substances in erythrocytes was significantly lower with seaweed supplementation compared to controls (p<0.05). Catalase and glutathione peroxidase activities with seaweed supplementation were higher than the controls (p<0.05), but superoxide dismutase activity was not affected. We, therefore, conclude that ingestion of seaweed influences glycemic control, lowers blood lipids, and increases antioxidant enzyme activities.

This study was performed to investigate the serum lipid levels and fatty acid composition in middle-aged men and the influence of cardiovscular risk factors on them. Data for dietary intake, anthropometry , blood pressure, and general environmental factors were obtained and their relationship to serum lipid levels and fatty acid composition were analyzed in 303 healthy male subjects with a mean age of 43.8$\pm$6.4 years from June 1 to 22 , 1995. The prevalence of obesity was 26.7% by BMI and 11.2% by WHR criteria . The percentage of hypertensive subjects were 13.5% and 22.4% by systolic and diastolic blood pressure, respectively. Retinol, calcium , and roboflavin intakes were lower than the RDA for Koreans. The ratio of carbohydrate intake to total calories of the subjects was 70%. Ratios of P/M and n-6/n-3 were 1.02/1.05/1.00 and 11.1/1, respectively. The percentage of subjects who had serum TG, TC, LDL-C leves beyond the normal range were 19.5% , 13.5% and 8.6% respectively. Palmitic comprised 26.4% of serum total fatty acids, linoleic acid 19.4% and oleic acid 16.4. The waist circumference and ration of carbohydrate intake were related positively to TG level. Serum cholesterol level had positive relations with waist circumference, DBP, sugar intake, and income. There were positive relationships between SFA and bone fishes and vegetable oil intakes, MUFA and DBP while a negative a negative relationship was observed between PUFA and animal fat intake. Serum n-6 fatty acid was related negatively to carbohydrate intake and hot taste preference. N-3 fatty acid was related positively to fish intake and negatively to egg intake. These results suggest that to maintain adequate serum lipid levels and fatty acid composition, sugar, animal fat, and carbohydrate intakes have to be reduced, while consumption of vegetable oil and fish must be increased. It is also essential to control abdominal fat accumulation and blood pressure.

Objectives : This study was designed to investigate the effects of Nelumbinis Rhizomatis Nodus(NRN) on production levels of Blood Glucose and Serum Lipid Levels. Methods : This study is about changes of blood glucose levels, body weights, levels of food and water uptake, levels of total cholesterol in the body, triglyceride, Creatinine, and BUN production by NRN extract. Results : Treatment with NRN regulated blood glucose levels effectively, but treatment with NRN did not affect body weights, food and water uptake. In addition, treating with NRN also lowered levels of total cholesterol, which is important for diabetes, and also lowered levels of triglyceride, too. Serum Creatinine levels were not affected, but serum BUN levels were lowered by treating with NRN, which were elevated in diabetes. Conclusions : These results demonstrate that NRN is effective to treat DM level and also has anti-hyperlipidemic effect.

This study was carried out to examine how dietary protein and calcium levels in rats fed fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues. Male Sprauge-Dawley rats weighing approximately 200g were fed six purified diets which contained 18%(w/w) beef tallow, 1% (w/w) cholesterol, two source of protein, casein or isolated soy protein (ISP) and three levels of dietary calcium, 0.1%, 0.4% and 1.0%, first, for four weeks, and second, for eight weeks. The contents of the total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding serum lipid and cholesterol concentrations significantly decreased in rats fed 1.0% (w/w) level calcium, regardless of dietrary protein sources. After eight weeks, these concentrations were significantly lower in the rats fed soy protein than in casein-fed rats. As dietary calcium level increased serum and tissue lipid and cholesterol contents were decreased and fecal lipid excretion increased. It is concluded that hypolipidemic and/or hypocholesterolemic effects of soy protein and calcium were partly due to decrease in lipid absorption.

Objectives : Abnormal regulation of glucose and impaired lipid metabolism that result from a defective or deficient insulin are the key etiological factor in type 2 diabetes mellitus. The our study investigated the effects of Gamioknyeo-jeon (GO) on blood glucose and lipid metabolism improved by it in db/db mice (a murine model of type 2 diabetes mellitus).Methods : The animals were divided into 3 groups: Normal groups were not-treated C57BL/6 mice; Control groups were treated orally with DW in db/db mice; GO groups were treated orally with GO (200 ㎎/㎏/day) in db/db mice. After mice were treated with GO for 5 weeks, we measured AST, ALT, creatinine, BUN, body weight, food intake, blood glucose, insulin and lipid levels (total cholesterol, HDL cholesterol, and LDL cholesterol and atherogenic index(AI) and cardiac risk factor(CRF).Results : Serum AST, ALT, creatinine, BUN levels were not changed by GO do not show any toxic effects. GO groups were decreased in body weight, food intake and blood glucose level among compared to Control groups. Also, GO groups were found to have atherogenic Index and cardiac risk factor as well as lipid metabolism improvement (total cholesterol and LDL cholesterol decrease). Finally, GO groups were increased the insulin compared to Normal and control groups.Conclusions : We suggest that GO may have the control effects of diabetes mellitus by improving blood glucose control and lipid metabolism.

Objectives: Previous studies have obtained conflicting findings regarding possible associations between indices measuring carbohydrate intake and dyslipidemia, which is an established risk factor of coronary heart disease. In the present study, we examined crosssectional associations between carbohydrate indices, including the dietary glycemic index (GI), glycemic load (GL), total amount of carbohydrates, and the percentage of energy from carbohydrates, and a range of blood lipid parameters. Methods: This study included 1530 participants (554 men and 976 women) from 246 families within the Healthy Twin Study. We analyzed the associations using a generalized linear mixed model to control for familial relationships. Results: Levels of the Apo B were inversely associated with dietary GI, GL, and the amount of carbohydrate intake for men, but these relationships were not significant when fat-adjusted values of the carbohydrate indices were used. Triglyceride levels were positively associated with dietary GI and GL in women, and this pattern was more notable in overweight participants (body mass index [BMI] ${\geq}25kg/m^2$). However, total, low-density lipoprotein and high-density lipoprotein cholesterol levels were not significantly related with carbohydrate intake overall. Conclusions: Of the blood lipid parameters we investigated, only triglyceride levels were positively related with dietary carbohydrate indices among women participants in the Healthy Twin Study, with an interactive role observed for BMI. However, these associations were not observed in men, suggesting that the association between blood lipid levels and carbohydrate intake depends on the type of lipid, specific carbohydrate indices, gender, and BMI.
