Background : There are many korean women who have localized fat despite of they have normal or slightly over weight. The relationships of traditional diagnostic method with total body fat and body mass index had been reviewed in other study, but there is no study regarding the relationship of traditional diagnostic method and localized fat. So we designed this study to find out the relationships between localized fat and traditional diagnostic method among Korean high-school girls. Methods : This research was performed in 21 high-school girls with localized fat during April 2007. We measured body mass index, percent of body fat, waist circumference, hip circumference and means of both thigh circumference. Phlegm questionnaire, blood stasis questionnaire, cold-heat questionnaire, Korean eating attitude test-26 and questionnaire of Sasang constitution classification Ⅱ+ have been administered. Results : There were significant correlations between body mass index, percent of body fat and body size. Regardless of body mass index, they had high phlegm and heat pattern. Most of them are classified as Tae-um type person. Conclusions : High-school girls with localized fat had pattern of high phlegm, heat and characteristics of Tae-um person.

Objective: The current study aimed to investigate the impact of high-fat diets composed of different animal and vegetable fat sources on serum metabolic health markers in Japanese quail, as well as the overall lipid content and fatty acid profiles of the edible bird tissues following significantly increased dietary lipid supplementation. Methods: Fifty seven male quail were divided into six groups and fed either a standard diet or a diet enriched with one of five different fats (22% coconut oil, lard, palm oil, soybean oil, or sunflower oil) for 12 weeks. The birds were subjected to an oral glucose tolerance test following the feeding period, after which they were euthanized and blood, liver, breast, and thigh muscle samples collected. Total fat content and fatty acid profiles of the tissue samples, as well as serum uric acid, triglyceride, cholesterol, total protein, albumin, aspartate transaminase, and total bilirubin concentrations were assessed. Results: High-fat diet feeding had no significant effects on the glucose tolerance of the birds. Dietary fatty acid profiles of the added fats were reflected in the lipid profiles of both the liver and breast and thigh muscle tissues, indicating successful transfer of dietary fatty acids to the edible bird tissues. The significantly increased level of lipid inclusion in the diets of the quail used in the present study was unsuccessful in increasing the overall lipid content of the edible bird tissues. Serum metabolic health markers in birds on the high-fat diets were not significantly different from those observed in birds on the standard diet. Conclusion: Thus, despite the various high-fat diets modifying the fatty acid profile of the birds' tissues, unlike in most mammals, the birds maintained a normal health status following consumption of the various high-fat diets.

Anthocyanins, a class of flavonoids, are natural water-soluble pigments, mainly found in vegetables and fruits. Anthocyanins have attractive pharmacological activities, such as anti-oxidant, anti-inflammatory, anti-cancer, and anti-diabetic effects. The purpose of this study was to investigate the inhibitory effects of the anthocyanin-rich fraction (ANF) from purple sweet potato on high fat diet-induced insulin resistance and hepatic steatosis. C57BL/6J mice were assigned to the following groups (n=8 per group): normal fat diet (NF); high fat diet (HF); high fat diet with ANF 50mg/kg (ANF50). Normal fat or high fat diets were fed for a total of 17 weeks, and ANF was orally administrated for 8 weeks (from 10 to 17 weeks, five times/week). In our results, there were no significant differences in body weight, food intake, and tissue weight upon ANF supplementation. The levels of serum triacylglycerol, total-cholesterol, and glucose were also not affected by ANF supplementation. However, ANF supplementation significantly decreased serum insulin and HOMA-IR levels as well as prevented hepatic fat accumulation in high fat-fed mice. These results show that ANF may be beneficial for improving high fat-induced insulin resistance and protecting against development of hepatic steatosis.

The present study was conducted to investigate the effect of dietary supplementation of grape pomace on lipid peroxidation and related enzyme activities of rats fed high fat diet. Male Sprague-Dawley rats weighing about 90 g were assigned to 4 experimental groups of 8 rats on the basis of their body weight. The high fat diet contained additional 15% lard to AIN 93-based diet. Rats were fed experimental diets containing 5% grape pomace for 4 weeks. Dietary supplementation of grape pomace reduced serum concentration of lipid peroxide in rats fed high fat diet. Hepatic concentration of lipid peroxide tended to be lower by feeding grape pomace. Hepatic total glutathione content and GSH/GSSG ratio were increased by grape pomace feeding in normal or high fat diet groups. Hepatic superoxide dismutase activity of grape pomace group with high fat diet was induced significantly compared with high fat diet group without grape pomace. Hepatic catalase activity of high fat fed rats was induced by feeding grape pomace. Grape pomace diet increased glutathione-S-transferase and glutathione peroxidase activities in rat liver fed high fat. Hepatic glucose-6-phosphatase activity was not affected by dietary supplementation of grape pomace in rats fed high fat. These results suggest that dietary supplementation of grape pomace may alleviate lipid peroxidation through antioxidant effect in rats fed high fat.

Objectives : This study was performed to identify the effects of high frequency therapy on localized obesity. Methods : This trial was carried out in 12 volunteers. Volunteers were divided into 3 groups; upper arm group (n=4), thigh group (n=4) and abdomen group (n=4) according to local obesity type. Body weight and body fat were measured by Inbody 720 and CT (Computed Tomography) immediately before and following high frequency therapy. Diathermy was performed twice a week for 4 weeks for a total of 8 treatments. Results : In the upper arm group, body weight, body fat mass, fat area by CT scan and circumference were increased after treatment but not significantly (p>0.05). In the thigh group, body weight, body fat mass and circumference were decreased and fat area by CT scan was increased but both not significantly (p>0.05). In the abdomen group, significant differences were not found despite decreases in body weight, body fat mass, visceral fat and subcutaneous fat after diathermy (p>0.05). Conclusions : There was no significant effects of high frequency therapy on localized obesity.

The effects of dried green tea leaf powders on serum lipid concentrations were evaluated in rats. Sixty male Sprague-Dawley rats weighing $100{\pm}10g$ were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Normal fat diet and normal and high fat diets with 1% dried green tealeaf powders. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by dried green tea leaf powders groups. The concentrations of serum triglyceride in rats fed the dried green tea leaf powders were lower than those in other groups. The concentrations of total cholesterol in green tea leaf powders the were lower than those in high fat diet groups. The concentrations of HDL-cholesterol in serum of the dried leaf powders green tea were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the dried green tea leaf powders groups were tended to be lower than those of other groups. GPT and GOT were decreased in dried green tea leaf powders groups and than in the high fat group. LDHase was lower in the dried green tea leaf powders groups than in the high fat group. These results suggest that dried leaf powders green tea groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

The effects of dietary levan, high-molecular-weight $\beta$-2,6-linked fructose polymer, on adiposity, serum leptin and UCP expression in rats fed high fat diet were studied. The adipose tissue hormone, leptin has been proposed to be involved in the regulation of food intake and energy expenditure. Uncoupling protein (UCP), a mitochondrial protein that uncouples the respiratory chain from oxidative phosphorylation, generates heat instead of ATP, thereby increase energy expenditure. To determine whether the dietary levan may have the anti-obesity effect, 4 wk old Sprague Dawley male rats fed high fat diet for 6 wks to induce obesity, and subsequently fed one of three diets for further 6 wks: 1) high fat (40% of calories) diet without levan 2) with 3% (w/w) levan 3) with 5% levan. For the comparison, control group fed AIN-76A diet. Visceral and peritoneal fat masses were lower in high fat diet with levan groups compared to high fat diet group. The effect of levan was dose-dependent. Adipocyte size was significantly reduced in the levan diet groups compared to the no levan diet group. Serum cholesterol level was not affected by levan containing diet, while the serum HDL cholesterol level was higher in leven diet groups. In addition, serum triglyceride level was markedly reduced by levan containing diet, thus lower than that of control group. Serum leptin was reduced by levan containing diet and lower in 5% levan group compared to 3% levan group (p < 0.001), as a result, serum leptin and insulin levels of 5% levan group were reduced to level of control group. Futhermore, the serum leptin level reflected the adiposity. The expression of UCP 1, and UCP 2 in brown adipose tissue was up-regulated by levan containing diet. In conclusions, levan containing diet reduced adiposity and serum triglyceride but increased UCP expression in the obese rats fed high fat diet. (Korean J Nutrition 35(9) : 903~911, 2002)

This study was investigated the effect of aerobic exercise and chrysin supplementation on macrophage infiltration and lipolysis in high-fat diet mice. To accomplish the purpose of this study, C57BL/6 mice were fed high fat diet(60% fat diet) during experimental period. The animals were divided into 4 groups; NC (normal diet control, n=5), HC (high fat diet control, n=5), Hch(high fat diet with chrysin, n=5), and HME (high fat diet with aerobic exercise training, n=5). Exercise training was performed for 16 weeks on a treadmill running. As a result, macrophage marker, F480 and CD11c were significantly decreased in HME comparison with HD and Hch. Also, M2 macrophage marker CD11c, and lipolysis marker PRDM were significantly increased in HME compared with HC and Hch These findings suggest that regular aerobic exercise has beneficial effects to inhibit macrophage infiltration in high fat diet mice.

Effects of alchohol and fat content in a balanced diet on chemical composition and morphology of liver were investigated in growing rats. Fourth eight male rats of Sprague-Dawley strain weighing about 160g were divided into 4 groups ; high fat diet group, alcohol-administered high fat diet group, low fat diet group and alcohol-administered high fat diet group, low fat diet group and alcohol-administered low fat diet group. High and low fat diets supplied 30% and 12%, respectively, of total calorie intake from fat, and alcohol was given by adding ethanol in drinking waster at 10%. Diets contained adequate amounts of all nutrients required for rats, including lipotrpoic agents(choline and methionine) to minimize effects of factors other than alcohol on liver damage. Ratios of liver weight to body weight were statistically different among groups. Liver/dody weight ratios alcohol-administered rats were significantly higher than those of non-alcohol groups after 6 weeks treatment. Although total lipid and triglyceride per gram liver were increased in alcohol-administered rats, especially low fat diet fed rats, the values were not significantly different. Opticmicroscopical observation revealed increase in cell size and no change in morphology of liver. Examination of hepatocytes by electron microscopy showed that fat droplets were observed in all groups but enlarged in the alcohol-administered low fat diet fed rat. Contents of protein, cholesterol and phospholipid were not affected by alcohol consumption. The level of lipid peroxide was significantly lower in the livers of alcohol-administered rats than in the livers of non-alcohol groups. The results of this study indicate that even moderate alcohol drinking and dietary fat content did not affect any significant change in composition and morphology of liver until 6 week treatment but that even moderate alcohol drinking caused some signs of steatosis of liver.
