The effects of Bulnesia sarmienti water extract on lipid metabolism were investigated in type-1 diabetes rats. The rats were fed a basal diet and B. sarmienti water extract for 8 weeks. The rats were randomly assigned to each treatment group: normal, control, three kinds of treatment group (BWO: 0.45 mg/ml, BW1: 0.9 mg/ml, BW2: 1.8 mg/ml). After 8 weeks of experimental diets consumption, the body weights and food efficiency ratio of B. sarmienti water extract fed groups were not change with those in the control group. The concentration in plasma total-cholesterol, LDL-cholesterol, triglyceride were significantly decrease in the B. sarmienti water extract groups compared with those in the control group. Although it was not possible to observe blood glucose control effects of eight weeks of B. sarmienti water extract feeds in type-1 diabetes model, it was discovered that the feeds are highly effective in lowering the levels of blood lipid substances triglycerides, total-cholesterol, and LDL-cholesterol.

Effects of kimchi lactic acid powder (KL) on weight reduction and lipid-lowering activities were studied using rats fed high fat diet. Spraque Dawley (40 rats) were fed 20% (w/w) high fat diet far 8 weeks to induce obesity and divided equally into normal diet (ND), high fat diet (HFD), and 10 and 20% KL-added groups. Body weight of HFD was 150% (p<0.01) of ND, while those of HFK10 and HFK20 decreased by 13 and 15% compared to HFD, respectively (p<0.01). Amounts of visceral fats for HFK10 and HFK20 were decreased by 42 and 48% compared to that of HFD (198% of ND), respectively (p<0.01). B had greater effect on reducing visceral fats than body weight. Plasma triglyceride (155%), cholesterol (129%), and LDL (161%) concentrations of HFD, which had been significantly increased compared to ND, dropped by 26, 9, and 8% (p<0.01) in HFK10, and 35, 17, and 33% (p<0.05) in HFK20, respectively. Decreased HDL by high fat diet was re-increased by KL supplementation. KL showed lipid-lowering and liver-protecting effects in liver possibly by interrupting lipid absorption in the intestine either by absorbing lipids in their cell walls or degrading them rapidly. Increased excretion of TG and cholesterol in feces of HFK10 and HFK20 indicates KL might have similar role to dietary fiber.

This study was performed to investigate cholesterol improvement effects of adding fermented defatted soybean grit (FD) and FD added to 5 or 10% Corchorus olitorius (FDC). Cholesterol adsorption in the FD and FDC group was more than 70%. Apolipoprotein AI and CIII improved in HepG2 cells, and a greater improvement effect was shown in FDC than that in FD. We also investigated the effect of FDC on body lipid metabolism and a high-fat diet for 4 weeks. Rats were divided into control (Con), high-fat (HF), HF treated with 20% FD (HF-FD), and HF treated with 20% FDC (HF-FDC) groups. Plasma total cholesterol and low density lipoprotein-cholesterol concentrations, hepatic total cholesterol, and triglyceride contents were significantly lower in the HF-FDC group than those in the HF group. Additionally, fecal total cholesterol and triglyceride contents increased in rats treated with FDC. Hepatic 3-hydroxy-3-methylglutaryl-coenzyme A reductase activities were significantly lower in the HF-FDC group than those in the HF group.

Effects of Korean traditional soybean fermented foods on weight reduction and lipid lowering activities were studied using Spraque-Dawley (SD) rats fed a high fat diet. The rats were raised for four weeks after adaptation period on either a normal diet (ND, based on the AIN-93 diet), high fat diet (HFD, supplemented with 12% lard oil in the ND), or diets containing 10% of freeze dried Doenjang, Chungkukjang, Kochujang, or Samjang to HFD. The final weight, food efficiency ratio (FER) and the weight of adipose tissue were decreased significantly by the consumption of Doenjang and Samjang, compared to HFD (p<0.05). The contents of cholesterol and triglyceride increased by HFD were reduced by the fermented foods in liver and perirenal fat tissues of the rats, especially Doenjang and Samjang diets showed high lipid lowering activity. And TG and cholesterol contents in the plasma serum were simillar trend to liver and perirenal fat tissue. These results suggested that Korean traditional soybean fermented foods, especially Doenjang showed the highest weight reduction and lipid lowering activities of the rats fed high fat diet.

Objectives: This study was designed to investigate the effects of Valerianae Radix et Rhizoma Methanol Extract (VRME) on serum lipid levels in a high-fat diet-induced hyperlipidemic mice. Methods: Each 8 C57BL/6 mice were randomly assigned to normal diet group, high-fat diet control group, high-fat diet plus 100 mg/kg/day of VRME group. In order to induce hyperlipidemia, high-fat diets were supplied to control group and VRME group for four weeks. Normal diet group were supplied with general feed for four weeks. After that control group supplied only high-fat diets as feed, VRME group received oral administration of VRME with high-fat diets for three weeks. and normal diet group were supplied with general feed for three weeks. After seven weeks, the changes in the body weight, the plasma levels of total cholesterol, triglyceride, high density lipoprotein-cholesterol, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood glucose in serum were measured. Results: In our results, VRME did not affects weight gain, serum AST and ALT in high-fat diet-induced hyperlipidemic mice. Oral administration of VRME lowered levels of total cholesterol and triglyceride, which were elevated by induction of hyperlipidemia. and oral administration of VRME lowered blood glucose significantly. Conclusions: These results suggest that VRME could act as a potent antihyperlipidemic in therapeutics for hyperlipidemia.

This study examined the effects of four herbal sports drinks containing Prunus mume, Liriope platyphylla, and Acanthopanax senticosus fruit extracts on body fat and endurance of rats trained by a progressive loaded exercise program. Forty male Sprague-Dawley rats (6 weeks old) were divided into five groups and fed experimental diets for 6 weeks according to the following protocol: C, exercise-trained control group (n=8); A, exercise group with Acanthopanax senticosus extract (n=8); L, exercise group with Liriope platyphylla extract (n=8); PA, exercise group with Prunus mune fruit extract plus Acanthopanax senticosus extract (n=8); PL, exercise group with Prunus mune fruit extract plus Liriope platyphylla extract (n=8). Endurance was measured by a progressive loaded exercise test using a treadmill. PA and PL supplementation significantly extended time to exhaustion compared to the control group (p<0.05). Further, the four herbal sports drinks all significantly reduced epididymal and interscapular white adipose tissue weights compared to the control group (p<0.05). Plasma triglyceride concentration was significantly lower in the A group compared to the control group. Plasma free fatty acid concentration was higher in the A group compared to the control group. On the other hand, Acanthopanax senticosus fruit extract supplementation tended to reduce the plasma glucose concentration compared to the control group. PA and PL supplementation significantly increased gastrocnemius muscle LDH activities compared to the control group (p<0.05). These results show that sports drink containing Acanthopanax senticosus improved endurance capacity, plasma lipids, and glucose concentrations. Sports drink with Prunus mume and Liriope platyphylla or Acanthopanax senticosus was synergistically improved endurance.

This study examined the effects of Bulnesia sarmienti ethanol extract on lipid metabolism in streptozotocin (STZ)-induced diabetic rats. Sprague Dawley rats were induced with diabetes mellitus by injecting STZ (45 mg/kg) into the tail vein, and were then divided into 5 groups: normal, STZ-control, and three experimental diabetic groups. The rats were fed a basal diet along with B. sarmienti ethanol extract for 8 weeks. According to the results, after 8 weeks of consuming the experimental diets, the body weights and food efficiency ratios of the B. sarmienti ethanol extract-fed groups were not different from those of the control group. However, the concentrations of plasma total-cholesterol, LDL-cholesterol, and triglycerides were significantly lower in the B. sarmienti ethanol extract groups as compared to those of the control group. Although a blood glucose control effect was not observed after the eight weeks of B. sarmienti ethanol extract treatment in this type-l diabetes model, it was discovered that the experimental diets were highly effective at lowering levels of serum lipids, including triglycerides, total-cholesterol, and LDL-cholesterol.

Although negative evidences of trans fatty acids(tFAs) are gradually increasing, the hypercholesterolemic effect of tFAs are controversial and its biological significances are still not known. The objective of this study was to examine the effect of dietary tFAs on cholesterol metabolism and membrane fluidity in rats. Animals were fed diets containing 0.5% cholesterol and 20% test fats(margarine, butter, corn oil) for 8 weeks. Each test fats(margarine, butter, corn oil) contained 25%, 8.5% and no tFAs, respectively, Plasma total triglyceride(TG) were not different among diet treatments. Feeding trans fat diets (margarine and butter) lowered plasma cholesterol. Specially, butter diet elevated LDL-cholesterol and decreased HDL-cholesterol levels, resulting in the highest atherogenic index among diet treatments. Hepatic cholesterol concentration and HMG CoA reductase activity were also decreased, whereas fecal excretion of cholesterol was increased in trans fat-fed animals. trans fat containing diets also decreased hepatic membrane fluidity. From these results, it can be concluded that hypercholesterolemic effect of tFAs can be modulated by the fatty acid composition of diets, but its spatial cofiguration may help behave like saturated fatty acid in membrane fluidity.

The purpose of this study was to obtain reference data of parameters for hematological health diagnosis in cultured freshwater fish and also evaluate application of automatic dry-type chemistry analyzer (FUJI DRI-CHEM 3000) used to those blood tests. A blood profile of total 200 fish for rainbow trout (Onchorhynchus mykiss), israel carp (Cyprinus carpio), tilapia (Oreochromis niloticus) and eel (Anguilla japonica) cultured in Inland Fisheries Research Institute of NFRDI was determined by hemoglobin (Hb) and plasma chemistry tests: total protein (TP), albumin (ALB), alkaline phosphatase (ALP), blood urea nitrogen (BUN), lactate dehydrogenase (LDH), triglyceride (TG), total cholesterol (TCHO), creatinine (CRE), aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose (GLU). The values of ALT, TG, LDH, ALB, TCHO, AST and ALP were outside from the minimum and/or maximum of the established detectable range of the analyzer. ALT and TG were not detectable in the range of 67%~61.5%. LDH, ALB and TCHO were not detectable in the range of 36~17%. AST and ALP were not detectable in the range of 5.5~0.5%. However, the values of BUN, CRE, GLU, Hb and TP were below the detectable limits of the analyzer.
