This study evaluated the weight reduction effect of Angook cereal mixture. The cereal mixture was prepared with barley, unpolished rice, corn, soybean, Garcinia cambogia, guar-gum, maltodextrin, glucomannan and a vitamin mixture. Eighteen female college students participated in this 8 weeks weight control program. All subjects were randomly assigned to the treatment and placebo groups. Mean energy intake of the treatment group was $1,356.4{\pm}79.9\;kcal$ (carbohydrate: 67.1%, protein: 18.7%, fat: 14.2%) and placebo group consumed $1,367.6{\pm}71.8\;kcal$ (carbohydrate: 64.2%, protein: 19.7%, fat: 16.1%) during program. The placebo group lost $3.9{\pm}0.8\;kg$ of body weight and the treatment group lost $5.9{\pm}0.7\;kg$ of body weight. There were significant differences in the decrease of total body weight, absolute fat mass, waist circumference (WC) and hip circumference (HC) between the two groups (p<0.05), however, the lean body mass was not significantly decreased in the treatment group compared to the placebo group. There were no differences in the changes in blood glucose, total-cholesterol, HDL-choloesterol, LDL-cholesterol and triglycerides between groups. These findings suggest that the intake of Angook cereal mixture may be beneficial for the reduction of the body weight, absolute fat mass, WC and HC.

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.

This study was carried out to investigate the effect of Meristotheca papulosa on lipid concentration of serum and liver in rats fed high fat diet for 4 weeks. Experimental groups ere divided into normal group (5% corn oil), high fat diet group (5% corn oil+20% lard), high fat diet and 5% or 10% Meristotheca papulosa treated group. The weights of kidney, heart and tests were not significantly different among the group, but weight of liver was significantly decreased by supplement of Meristotheca papulosa (10%). The contents of serum total lipid, trigly-ceride, total cholesterol, free cholesterol, cholesterol ester and atherogenic index were decreased, while HDL-cholesterol was increased by Meristotheca papulosa supplementation compared to high fat diet group. Meristotheca papulosa supplement has obvious effects on lowering hepatic total lipid, triglyceride and total cholesterol. Our findings suggest that Meristotheca papulosa supplement can improve lipid metabolism in high fat fed rats.

This study was designed to investigate the effect of Pueraria radix extract on lipid metabolism in the rats fed high fat diet. Male sprague dawley rats were given 5% Pueraria radix extract and fed diet containing 20 weight % fat. The results obtained were summarized as follows. Serum ALT and AST activities were reduced by Pueraria radix extract. Levels of total lipid, total cholesterol and triglyceride in the serum were higher in the HF group than in the control, but showed no significant differences between control and HF Pue group. Liver total lipid, total cholesterol and triglyceride contents were increased by high fat diet, but were lower in the HF Pue group than in the HF group. Fat absorption rate was increased with high fat diet feeding and higher in the HF Pue group than in the HF group.

Obesity can be defined as a metabolic disease due to an increased fat accumulation in the body caused by an imbalance of calorie intake and output The prevalence of obesity has increased substantially over the past 2-3 decades in developed and developing countries. The health impact of weight gain is so marked that obesity has now been classified as a major global public health problem In order to investigate the effect of diet conversion and oral administration of Platycodon grandiflorum extracts on the treatment of obesity, male Spraque-Dawley rats were divided into four groups: a group converted to normal diet (Control group), a group maintained high fat (30%) diet (H), and two groups with Platycodon grandiflorum extract added to the previously mentioned two groups. All animals were fed high fat diet for 7 weeks to induce the obesity. Then they were divided as mentioned above. Animals were fed experimental diet and Platycodon grandiflorum extract (150 mg/ml/rat/day) for 7 weeks. Body weight, adipose tissue weight (subcutaneous, epididymal, peritoneal fat pads) and serum lipids (total cholesterol and triglyceride) showed some differences among groups. The Platycodon grandiflorum feeding markedly decreased both body weight and adipose tissue weight in control group compared to H, high fat diet maintaining, group. Platycodon grandiflorum extracts significantly decreased the concentrations of serum lipids compared to H group. Fat cell numbers and sizes were significantly reduced in the oriental medicinal herb extract administrated group. Increased fatty acid binding protein (FABP) expression in high fat diet group was decreased by the dietary conversion to normal diet and the oral administration of Platycodon glandiflorum extracts. In contrast, there was no significant effect on FABP expression in the high fat maintenance group. In this study, the conversion from high fat diet to low fat or normal diet had a beneficial effect on body weight loss and serum lipid profiles. Dietary Platycodon glandiflorum extracts had an additive beneficial effect on the prevention and treatment of obesity.

The purpose of this study was to investigate the relationship among nutritional status, serum lipids and leptin of 134 elementary school students with different obesity index residing in Kyunggi-do, Korea. Subjects were assigned to under weight, normal weight or over weight group according to the their obesity index. Their nutritional status, serum lipid and leptin levels were evaluated based on 24-hr dietary recalls, anthropometric measurements and blood analysis. The mean weight, height and obesity index of total subjects was 150.8cm, 45.6kg and 5.4%. The mean % of body fat was higher while LBM and TBW (total body water) were lower in over weight subjects than those of other two groups. Total food, plant protein, carbohydrate, and vitamin C intakes of underweight male students were lower than those of overweight male students. The consumption of total fat was the highest in the female normal weight subjects and the lowest in female overweight subjects. Male students consumed more plant protein and vitamin C than female students. The mean daily intake of vitamin B$_2$, calcium and zinc of all subjects did not meet the Korean RDA. Also, iron intake of female students was lower than the Korean RDA. The mean level of serum leptin was the highest in male and female overweight subjects (p＜0.001). The HDL-cholesterol level was the highest in the underweight group of male subjects (p＜0.05) and in the normal weight group of female subjects (p＜0.001) The serum level of leptin and atherogenic index (AI) of females were higher than those of males. Serum leptin of total subjects had significantly positive correlation with obesity index, weight, SBP, body fat, cholesterol intake, serum triglyceride, and AI. However, serum leptin was negatively correlated with LBM, TBW, intake of plant protein, vitamin B$_1$, vitamin C and serum HDL-cholesterol. Obesity index was also positively correlated with weight, SBP, body fat, serum triglyceride and AI. To summarize the results, the vitamin B$_2$, calcium, zinc, iron and fiber intakes should be supplied to elementary school students, especially those who were overweight. The average serum leptin level of students showed remarkably positive correlation with obesity index, body fat, serum lipids and AI. Also, it was suggested that the serum leptin might be related to the dietary factors like cholesterol, plant protein, vitamin B$_1$ and vitamin C of elementary school students.

The purpose of this study was to investigate the gene profiles that were up- or down-regulated in the livers of high-fat diet-induced obese mice and $db_-/db_-$ mice with deficient leptin receptor. C57/BL6 normal mice and $db_-/db_-$ mice, respectively, were divided into two groups and fed a standard or high-fat diet for four weeks. Liver weight was unchanged in the normal mice but the high-fat diet led to a 10% weight increase in the $db_-/db_-$mice. Adipose tissue mass increased by about 88% in the normal mice that were fed a high-fat diet and by about 17% in the $db_-/db_-$mice on the high-fat diet. In terms of serum lipids, total cholesterol significantly increased in mice on the high-fat diet. Microarray analysis was carried out using total RNA isolated from the livers of standard or high-fat diet-fed mice of the normal and $db_-/db_-$ strains. The change of gene expression was confirmed by RT-PCR. About 1.6% and 6.8% of total genes, respectively, showed different expression patterns in the normal mice fed the high-fat diet and $db_-/db_-$ mice. As a result of microarray, many genes involved in metabolism and signal pathways were shown to have different expression patterns. Expression of Mgst3 gene increased in the livers of normal and $db_-/db_-$ mice that were fed a high-fat diet. Wnt7b and Ptk9l were down-regulated in the livers of the normal mice and $db_-/db_-$ mice that were fed a high-fat diet. In conclusion, a high-fat diet induced obesity and affected gene expression involved in metabolism and signal pathway.

Objectives This study aimed to investigate the effect of Bangkibokryeong-tang (BBT, Fangjifuling-tang) on blood glucose and body fat in high-fat diet-induced obese mice. Methods The experimental animals were divided into five groups- normal diet-fed control (ND), high-fat diet-fed control (HFD), HFD+BBT 75, HFD+BBT 150, and HFD+olistat as a positive drug control group. Markers of obesity, such as body weight, organ weight, diet efficiency, and serum levels of total cholesterol, triglycerides, lipid content, leptin, adiponectin, glutamic oxaloacetic transaminase (GOT)/glutamic pyruvic transferase (GPT)/lactate dehydrogenase (LDH), blood glucose, and insulin, were measured. Furthermore, results of the oral glucose tolerance test and ${\alpha}-glucosidase$ inhibition activity were examined in obese mice. Results Mice treated with BBT demonstrate lower body and organ weight, and reduced weight gain and food efficiency than that in the HFD-only control group. In addition, BBT decreased lipid accumulation in the liver and the levels of enzymes such as GOT, GPT, and LDH in the serum. Furthermore, the levels of triglycerides, total cholesterol, low density lipoprotein (LDL), and leptin were decreased in the serum but the levels of high density lipoprotein (HDL) and adiponectin were increased in the BBT-treated group compared with the control group. The BBT-treated group also demonstrated decreased blood glucose and insulin concentrations induced by feeding on a high-fat diet and improved glucose tolerance. Conclusions Based on the results above, BBT may reduce body fat and hyperglycemia in HFD-induced obesity. This suggests that BBT may be clinically useful in the treatment of obesity.

Objectives : The researcher investigated the anti-obesity effect of Alismatis Orientale Rhizoma(AP) water extract in mice fed a high fat diet and focused on the analysis of local area adipose tissue. Methods : Male ICR mice were divided into three groups, which were fed either a normal AIN diet, a 45% high fat diet (CT group), or a high fat diet and orally administration with a concentrations of 100 mg/kg (AP100 group) and 300 mg/kg body weight (AP300 group) for eight weeks. Results : As compared with CT group, AP100 group showed significant reductions in absolute weight of liver. As compared with CT group, AP100 group and AP300 group showed significant reductions in weight gain and relative weight of total fat. AST, triglyceride, total-cholesterol levels from the AP 100 group and 300 group were significantly lower than those of the CT, and ALT, LDL-cholesterol levels from the AP 100 group was significantly lower than those of the CT. But serum HDL-cholesterol levels from the AP 100 group and 300 group were significantly higher than those of the CT. And serum adiponectin levels from the AP 100 group was significantly higher than those of the CT. In result of real time PCR, all mRNA expression(PEPCK, G6Pase, PGC-$1{\alpha}$ and $ERR{\gamma}$) of two experimental groups were significantly decreased compared to those of CT group. The treatment with AP on local abdominal area made a fat cell size lessen on the fat tissue in the abdominal cavity and subcutaneous area. Conclusions : These results suggest that AP has an anti-obesity effect and the effect is mediated by inhibition of fat gain.
