Effects of powdered siho(bupleuri radix) on serum and liver lipid composition and antioxidative capacity were investigated in rat fed high oxidized fat. Sixty male Sprague-Dawley rats weighing 161.25$\pm$2.51g were blocked into four groups according to body weight and raised seven weeks with basal diet(normal group), basal diet and 10% oxidized fat(control group), basal diet, 10% oxidized fat and 2% powdered siho(2% powdered siho group) and basal diet, 10% oxidized fat and 3% powdered siho(3% powdered siho group). Feed intake, body weight gain and feed efficiency were not significantly different among oxidized fat diet groups. The values of total cholesterol and triglyceride in plasma and liver showed no significantly different(p>0.05) in the oxidized fat diet groups. Plasma HDL-cholesterol showed atendency to increase in powdered siho diet groups. The values of thiobarbituric acid in plasma and liver were lower in the powdered siho diet groups than control group. Plasma GOT and GPT activity showed a tendence to decrease in powdered siho groups. Liver glutathione peroxidase activity showed a tendence to increase in powdered siho diet groups. Thus, it seems that powdered siho had some antioxidative elements.

The principal objective of this study was to determine the effects of defatted soybean grits (DSG) on body lipidmetabolism with 4 weeks of feeding on a high-fat diet. The rats were divided into the following 4 groups: control group (Con), control group treated with 20% DSG (C20D), high-fat group (HF), and high-fat group treated with 20% DSG (HF20D). The plasma total cholesterol and LDL-cholesterol concentrations were significantly lower in the HF20D group than in the HF group. On the other hand, the DSG supplement resulted in a significant increase in plasma HDL-cholesterol levels. The DSG supplement reduced the hepatic total lipid, total cholesterol, and triglyceride contents as compared to what was observed in the HF diet groups. In addition, the fecal total cholesterol and triglyceride contents increased in the DSG treatment groups. The hepatic HMG-CoA reductase activities were demonstrated to be significantly lower in the HF20D group than in the HF group. These results showed that the DSG powder lowered plasma cholesterol levels, tissue lipid contents, and cholesterol accumulation in the rats.

As the obesity has been known to be related with the hyperlipidemia, cardiovascular disease, cerebral apoplexy, fatty liver, and other chronic diseases, recent researches have focused on the functional food materials and their anti-obesity activities. This study was performed to study the effects of vanilloid family capsaicin, major pungent ingredient of hot chillies and peppers, on anti-obesity activities. ICR male mice were fed one of the pellet diet, basal diet, and high fat diet with capsaicin (45 $\mu\textrm{g}$/day) solution for 5 days. Mice in the corresponding control groups were given water for 5 days. In results, capsaicin reduced body weights in any diet groups. Percent weight and cell size of the abdominal white adipose tissue in mice on the high fat diet with capcaicin were significantly lower compared with those in mice on the high fat diet with water. However, percent brown adipose tissue weight per body weight in mice on the high fat diet was not affected by capsaicin. Capsaicin reduced the levels of s-triglyceride and s-total cholesterol in the pellet diet or high fat diet groups. There was no difference in the s-protein levels between the capsaicin group and the control water group. These data indicate that 1) orally administered capsaicin has a reducing effect on the blood triglyceride and total cholesterol levels, and 2) capsaicin has lowering effects on the body weight, percent weight and cell size of the abdominal white adipose tissue.

This study aimed to investigate the effect of acorn powder and starch on the blood parameters of mice fed a high-fat diet. The moisture, crude ash, crude protein, and crude fat contents of acorns were $37.99{\pm}0.37%$, $1.61{\pm}0.06%$, $4.36{\pm}0.18%$ and $3.22{\pm}0.15%$, respectively. Acorn powder and starch contains antioxidant minerals such as selenium and zinc. The iron content was significantly higher in acorn powder than in acorn starch (p<0.05). The total cholesterol concentration was $148.50{\pm}29.72mg/dL$ in the high-fat starch diet (HFS) group, while in the high-fat diet (HF) group it was $201.50{\pm}39.15mg/dL$ (p<0.05). Serum LDL-cholesterol concentrations were significantly lower in the HFS group ($50.50{\pm}10.79mg/dL$) than in the HF group ($62.00{\pm}20.85mg/dL$; p<0.05). The serum $IL-1{\beta}$ levels in mice were not significantly different between the groups. IL-10 levels were higher in the HFP group than other groups. There is a need for strong recognition that acorns are good ingredients worldwide. It is required to develop various products using acorn powder and starch powder. There is also a need for a strategy to globalize food using acorns.

High-protein fermented whey beverage (FWB) was manufactured using whey protein concentrate (WPC) and Lactobacillus plantarum DK211 isolated from kimchi. This study was designed to evaluate the anti-obesity activity of FWB in male rats fed a high-fat diet. Male Sprague-Dawley rats were randomly assigned to three groups (n=8 per group). The three groups differed in their diet; one group received a normal diet (ND), another, a high-fat diet (HD), and the third, a HD plus fermented whey beverage (HDFWB), for 4 wk. Supplementation with FWB (the HDFWB group) prevented weight gain and body fat accumulation. The food intake in the HDWFB group was significantly lower (p<0.05) than that of the HD group. The HDWFB group also showed a significant decrease in organ weights (p<0.05), except for the weight of the testis. There was a significant decrease in total cholesterol, LDL-cholesterol, and triglycerides in the HDFWB group compared with the HD group (p<0.05), but there was no significant difference in serum HDL-cholesterol levels among the experimental groups. Rats ingesting FWB (the HDFWB group) also showed a significant decrease in blood glucose levels, and plasma levels of insulin, leptin, and ghrelin compared to HD group (p<0.05). These results indicate that FWB has beneficial effects on dietary control, weight control, and reduction in fat composition and serum lipid level; consequently, it may provide antiobesity and hypolipidemic activity against high fat diet-induced obesity in rats.

Objectives: This study was designed to investigate the effect of Gami-cheongpyesagan-tang extract (GCST) on high fat diet-induced obesity in rats. Methods: The mice were divided into six groups; normal diet control, high fat diet control (HFD), HFD+GCST administrated group (100, 200, and 400 mg/kg) and olistat-admistrated group. Obesity was induced by high fat diet (45%) for 7 weeks in mice, and GCST was administrated orally every day for 7 weeks. The body weight, food intake, and serological markers such as total cholesterol, triglyceride, lipid contents, leptin, adiponectin and glutamic oxaloacetic transaminase/glutamic pyruvic transaminase were measured in mice. The mRNA expression of obese-associating genes such as sterol regulatory element-binding protein (SREBP)-1c, fatty acid synthase (FAS), stearoyl-CaP desaturase (SCD-1), peroxisome proliferator-activated receptor $(PPAR)-{\alpha}$, COA oxidase (ACO), and carnitine palmitoyltransferase ($CPT-1{\alpha}$) was analyzed by reverse transcription polymerase chain reaction. Results: The administration of GCST at 400 mg/kg, significantly reduced the increase of body weight and food intake as well as food efficiency compared to HFD group. GCST decreased the serum levels of triglyceride, total cholesterol, low-density lipoprotein-cholesterol, leptin in HFD control group and inhibited lipid accumulation in liver and adipose tissues, but did not increase high-density lipoprotein-cholesterol. In the liver tissues of GCST administrated HFD group, the mRNA levels of SREBP-1c, FAS and SCD-1 were decreased and the mRNA levels of $PPAR-{\alpha}$, ACO, and $CPT-1{\alpha}$ were increased. Conclusions: These results indicate that GCST could improve high fat diet induced obesity through inhibiting the hyperlipidemia in fatty Liver. It suggest that GCST may be used clinically for declining the accumultion of body fat with hyperlipidemia.

The present study was undertaken to determine the metabolic effect of various levels of fat in the diet. Forty males and the same number of females weighing $35{\pm}29$ were divided into three experimental groups and one control group, 10 rats each in both sexes. The dietary lipid contents were included in three levels, 2% as low, 30% as high and fat free diet in order to reflect the lipid consumption of present Korean diet. 20% sugar casein diet were employed as standard for control animals. This study was carried for 16 weeks. After these period animals were sacrificed to collect the internal organs and blood samples by heart puncture. In the result of this study, high fat diet group is lower than low fat diet group in the body weight gain, food efficiency ratio, protein efficiency ratio, urinary nitrogen and organ nitrogen contents were same trend but there is no significant difference in these respects. It was noteworty that high, and free fat diet group revealed more glucose total protein, albumin and globulin contents in the serum than other compared groups. It can be concluded that fat content whether low or high are free in the diet did not show significant effect on body nitrogen metabolism. But 30% high fat diet increased the total lipid and total cholesterol contents in the liver and the serum. This fact can be interpreted that 2% low fat diet and fat free diet do not need to increase the amount of fat content in the diet as high as 30% fat diet. This result might indicate the one possible reason to decide the recommanded dietary fat levels in Korean diet.

Recently it has been reported that vitamin A and retinol binding proteins (RBPs) in blood and urine were changed in the condition of diabetes mellitus or hyperlipidemia. Fruits and vegetables are recommended to consume for the people suffered from these chronic degenerative diseases. The main components of fruits and vegetables are dietary fibers, for example cellulose and pectin, of which function to affect the absorption and excretion of dietary fat and fat-soluble substances. This study was conducted to investigate the effect of dietary fibers on RBPs mRNA expression in liver, small intestine and serum of rat fed high fat diet during 4 weeks. Sprague-Dawley rats, weighing 121g on average, were divided into four groups; (Control; $17\%$ fat & cellulose supplement diet, HF0: $25\%$ fat & fiber free diet, B:.Uc: $25\%$ fat & cellulose supplement diet and HF0: $25\%$ fat & pectin supplement diet) . The rats fed high fat diet groups (HF0, HFC, HFP) tended to consume the food less than the control group, but FER of HF0 groups was significantly higher than the control (p < 0.05) . The weight of adrenal gland in high fat diet groups (HF0, HFC, HFP) was significantly less than the control. Total lipid in feces daily excreted and in liver did not show any significant differences among the groups. Total cholesterol in HFP group was significantly different from that of HFC group. Serum total cholesterol and triglyceride in other group tended to lower than other groups and HDL cholesterol higher. Consequently, AI (atherogenic index) was the lowest in HFP group. Vit A contents in feces daily excreted tended to lower in high fat diet groups (HF0, HFP) compared to the control group. That content in adrenal gland was the lowest in HF0 group, but not in liver. In HFP group were down-regulated cRBPI mRNA in liver and cRBPII mRNA in small intestine and up-regulated RBP and transthyretin expression in serum compared to the other groups. In conclusion, dietary fibers, especially pectin, in high fat diet might down-regulate the expression of CRBP I, CRBP II mRNA in liver and small intestine, but increase the secretion of RBP into serum and therefore inhance the bioavailability of Vit A through the body.
