To investigate the efficacy of extract of Tartary buckwheat (F. tataricum Gaertn.) in high fat diet (HFD) in mice, the F. tataricum Gaertn. extract (FTE) was orally administered to mice with a HFD at 300 mg/kg/day for 4 weeks. Our results show that FTE significantly inhibited fat accumulation. Moreover, FTE markedly reduced the final body weight with a decrease in epididymal adipose tissue mass and adipocyte size compared with the untreated HFD-induced group. Additionally, FTE ameliorated serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels. The results show that Tartary buckwheat possesses hypocholesterolemic effect through downregulating lipid metabolism. Further studies are required in this area to strengthen the anti-obesity effects of FTE with active component, and it can be used a pro-drug instead of whole extract.

Nutritive value of lipids was associated with composition of fatty acid. Unvalance diet may increase the incidence of diseases. Abundant of EPA and DHA, polyunsaturated fatty acid, were contained in fishes. Studies on 10 kinds of fishes, lipid components were determined. The results were as follows; 1. The content of crude fat 18.1% were high in eels, on the contrary the content of EPA 0.1% and DHA 0.1% were low. The content of crude fat were low in mackeral and sadrine, but the content of poly unsaturated fatty acid were high. 2. Iodine value 189 was high in sadrine, consequently, this results showed the interrelation between Iodine value and the content of polyunsaturated number. 3. The content of crude fat 1.3% in flounder(sole) were low and the content of cholesterol 20 mg% were lowest in present studies.

Blood lipid levels in rats with high fat-fed hyperlipemia were determined after intraperitoneal administration of a methanolic extract of Prunus davidiana Fr. stems. Administration of the methanolic extract for 6 days produced a significant decrease of blood triglyceride and total cholesterol, and the atherogenic index was also improved. In addition to the hypolipemic effect, the methanolic extract was also shown to be effective in reducing an elevated level of glucose in rats with hyperlipemia resulting from high-fat feeding. On the other hand, blood triglyceride and total cholesterol in rats fed with stock diet were not affected by administration of the methanolic extract even if there was a tendency to decrease. No significant change was also found in the level of glucose. Thus, it is suggested that this methanolic extract probably may increase the metabolic utilization only when fed with excess fat.

In this study, we investigated the anti-obese activity of sevennight extract in high fat diet-ob/ob C57BL/6J mice by oral administered for 1 weeks. Mate water extract (MATEWi) was found to lower whole body and epididymal adipose tissue weights and lowered plasma levels of triglyceride (TG) and total cholesterol (TC), HDL and LDL, compared to those in high fat fed ob/ob group. These results suggest that Mate extract ameliorates obesity through activation of lipogenic enzymes and FA oxidation resulting from phosphorylation of AKT and GSK-$3{\beta}$, and could be developed as a potential therapeutic agent for obese mices.

Male rats of 2 months-old(young), 6 months-old(adult) and 30 months-old(old)were fed 8 or 16 weeks to investigate the e(feats of dietary fat level on the lipid metabolism in the different stages of aging. The response of 30 month old rats to dietary fat level differed from either 2 or 6-months old rats. In 30-months old rats, dietary fat level had a little effect on weight gains, lipid content of serum as compared with other two age groups. Young rats showed higher body weight gain, F.S.R, and PER compared with aged rat. The younger and the more high fat fed the rats were, the more body weight gains, FER and PER showed. Weight of liver and kidney was increased in aged rats but ratio per unit weight of liver and kidney was not affected by age. Serum lipid content was higher in aged rat compared with the young and liver lipid content was higher in high fat diet fed rats. But TG of liver and serum was not changed with aging process. Intake, excretion and absorption of lipid was not changed by age of animals. but absorption was decreased as experimental period was increased.

This study was carried out to examine obesity and nutrition knowledge in male employees who had high educational background. The subjects in this study were 213 persons aged 20 to 40(52.6% among them were 20s) Ninety six percent of them graduated university. Most of them took exercise regularly and showed less smoking tends but drank frequently. Twenty two point one percent of the subjects had diseases specially gastrointestinal disease. anthropometric results were height:172.1cm; weight :70.5kg;BMI:23.8;fat mass:16.1kg; fat percentage :21.3% ;LBM :55.4kg ; and TBW : 40.9kg BMI and fat percent were used for screening obesity. According to BMI the normal group (20∼25) was 64.6% the oberweight group (25∼27) was 18.4% the underweight group (<20) was 9.9% and the obese group (>27) was 7.1% Based on fat percentage, the normal group (14%∼23%) was 58.5% the obese group(>23%) was 36.0% and the underweight group(<14%) was 6.5%. There was significant relationship be-tween age or marriage and BMI or fat percentage. But the rest of socio-dmographic and health-related factors didn't affect signifincantly. There was no difference in nutrition knowledge of subjects by obesity rate however obese group was more sensitive to the foods related to weight gain.

Obesity is a global pandemic that is increasing throughout most of the world. Increases in obesity are not restricted to highly industrialized countries, but have been observed in newly developed and developing countries as well. Obesity is associated with increased risk for non-insulin dependent diabetes mellitus, coronary artery disease, and some types of cancer. Tragically, eliminating food shortages in developing countries may result in substituting heart disease, diabetes, and cancer for malnutrition. There are many approaches to reducing obesity, including dietary modification, surgical interventions, and drug therapies. However, only dietary modification has the potential to be effective on a global scale. Public health measures in the United States have sought to reduce obesity by reducing the intake of dietary fat. While these efforts have succeeded in reducing dietary fat, obesity has continued to increase, suggesting that moderate fat reduction may not be effective. Other proposed diets include low-carbohydrate diets, low glycemic index diets, and very low fat diets. While all of these diets may be effective for some people, they are not satisfactory for public health policy. In fact, the ratio of fat to carbohydrate may not be as important as previously believed. Humans may be well suited to adapt to diets as varied as a high carbohydrate tropical diet consisting mostly of fruits to the high fat Eskimo diet consisting largely of animal foods. Either extreme may be healthful if providing adequate, but not excessive, energy and adequate amounts of micronutrients. Public health measures may need to focuss on reducing the overconsumption of inexpensive and convenient foods.

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.

Objectives: The purpose of this study was to investigate the ameliorative effects of the Epimedium koreanum Nakai (EK) on menopausal obesity in mice. Methods: To induce the menopausal obesity, female C57BL/6J mice were ovariectomized and fed with high fat diet for 12 weeks. 17β-estradiol was injected as a positive control and the extract of EK was orally administered 5 times per week for 6 weeks. Body weight, uterine weight and visceral fat weight were measured. The size of the adipocyte in visceral fat tissues was estimated by Hematoxylin and eosin staining. Fasting glucose level was estimated in serum. Results: Body weight and visceral fat weight were significantly decreased by EK treatment, while the uterine weight/body weight was increased in high fat diet-fed ovariectomized mice. The diameter of adipocyte in the visceral fat tissues was markedly reduced in EK-treated menopausal obese mice. In addition, the fasting blood glucose level was inhibited by oral EK administration. Conclusion: In conclusion, these results showed that EK has ameliorative effects on overweight after menopause. EK could be one of the alternative therapy for treating menopausal obesity.

This study was conducted to investigate the effects of vitamin E supplementation renal lipid peroxidation in high fat diet and adriamycin (ADR) induced experimental nephrotic syndrome model rats. Treated rats were injected intraperitoneally with ADR (2mg/kgBW/wk) once a week for four weeks. control rats were injected with saline solution instead of ADR. The rats in each group were fed experimental diets of three levels of vitamin E for 10 weeks: Normal (501U/kg diet), high (5,000IU/kg diet), excess (7,500IU/kg diet). The high fat diet and ADR treatment was performed to induce the decrease of kidney functions. Serum total cholesterol was significantly decreased by the excess supplementation. But there was no effect of vitamin E supplementation on serum total lipid and triglyceride. Thiobarbituric acid reacting substances(TBARS) was significantly decreased at high and excess supplementation. Glutathione reductase (GR), glutathione peroxidase ({TEX}$GP_{x}${/TEX}) and catalase activities (CAT) were measured as antioxidative enzymes. The renalglutathione reductase (GR) and catalase activities (CAT) were inclined to elevate by vitamin E supplementation. Thus the vitamin E supplementation was found to have an antioxicant effect. These results suggested that vitamin E supplementation could alleviate the changes in renal lipid peroxidation.
