Obesity is caused by unbalance of energy intake and expenditure, which results in extra accumulation of adipose tissue. Obesity is directly related to metabolic diseases such as diabetes, hyperlipidemia, fatty liver and so on. To investigate the anti-obesity effects of Scutellariae Radix, 70% EtOH extract and water extract of it were tested by in vitro and in vivo studies of fat accumulation. 3T3-L1 preadipocyte cell line was used in a in vitro study of fat accumulation. After 3T3-L1 cells were induced to differentiate into adipocytes, S. radix extract were added and fat accumulation was measured by oil red O staining. In vivo study showed that weight and epididymal/ retro-peritoneal adipose tissues were significantly reduced in mice fed Scutellariae Radix extract compared with control group. Especially, mice fed Scutellariae Radix extract showed reduced serum triglyceride and glucose levels. When adipose tissues were analyzed by microscope, mean adipocyte size was significantly reduced in Scutellariae Radix extract-fed mice. Therefore, this study showed inhibitory effects of Scutellariae Radix on in vitro and in vivo fat accumulation.

This study aimed to determine the anti-obesity effect of adding Wolfiporia extensa Ginns (W) to fermented pollack skin products in an obesity-induced animal model. The experimental groups were the normal diet group (C), high-fat diet group (HF), dried pollack skin (H1), fermented pollack skin (H2), and W of 0.1 (F2-WL), 0.3 (F2-WM), and 0.5 (F2), respectively. It was confirmed that adding W to fermented pollack skin reduced blood triglycerides, total cholesterol, and LDL levels, while increasing HDL levels. Wolfiporia extensa Ginns was effective in controlling weight and improving blood lipids in a dose-dependent manner. In histological analysis, findings of fatty liver induced by a high-fat diet were improved by the addition of H2 and W. Size and density of fat globules in the epididymis were decreased. In addition, the concentration of TNF-α was increased in the high-fat diet group, but decreased by the addition of fermented pollack skin and W. In conclusion, adding fermented dried pollack skin and Wolfiporia extensa Ginns was effective for weight control and blood lipid improvement. Thus, the use of by-products in functional foods is expected to have a high value in the future.

To investigate the efficacy of extract of Ginkgo Biloba seeds in high fat diet (HFD) in mice, the Ginkgo Biloba seeds extract (GSE) was orally administered to mice with a HFD at 300 mg/kg/day for 4 weeks. Our results show that GSE significantly inhibited fat accumulation. Moreover, GSE 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, GSE ameliorated serum high-density lipoprotein cholesterol levels. The results show that Ginkgo Biloba seeds possesses hypocholesterolemic effect through down regulating lipid metabolism. Further studies are required in this area to strengthen the anti-obesity effects of GSE with active component, and it can be used a pro-drug instead of whole extract.

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.

Objectives : Obesity is a metabolic disease resulted from various causes including nutritional disproportion, hormonal imbalance, and hypothalamic nuclei disorder. Samhwang-tang(Sanhuang-tang, SHT) is composed of 5 herbs (Ephedrae Herba, Scutellariae Radix, Typhae pollen, Acori Rhizoma and Ansu Semen) and is frequently used for obese patients. This study investigated anti-obesity effects of SHT on the rats. Methods : Obesity was induced by high fat diet (HFD), monosodium L-glutamate injection (MSG) and ovariectomy (OVX) in the Sprague-Dawley rats. Water extract of SHT was treated for 2 weeks, then changes of body weight gain and epididymal fat cell size were measured. In OVX animals, c-Fos and neuropeptide Y (NPY) expressions in hypothalamic nuclei were observed with immunohistochemistry. Results : SHT treatment demonstrated significant decrease of body weight gain in obesity induced by HFD and OVX, but not in obesity induced by MSG. SHT treatment demonstrated significant decrease of fat cell size in obesity induced by HFD, but not in obesity induced by MSG. On c-Fos and NPY expressions in hypothalamic nuclei, SHT treatment resulted significant decrease of immuno-reactivity of c-Fos and NPY in obesity induced by OVX. Conclusions : These results suggest that SHT has a weight loss effect against obesity induced by nutritional disproportion of diet intake and hormonal imbalance, especially without central nervous system disorder.

Objective: This experiment was studied the effects of various levels of crude glycerin (CG) in dairy goat diet on daily intake, milk yield, milk composition, some physical properties and some quality changes of goat milk after sterilization. Methods: Twelve 75% Saanen dairy goats (body weight = $49{\pm}3kg$; days in milk = $60{\pm}12d$) were randomly assigned in a completely randomized design to evaluate the effects of three experimental diets consisting of 0%, 5%, and 10% CG (dry matter basis) which were formulated to meet or exceed the nutrient requirements of goats. Experimental dairy goats were evaluated for feed and milk yield. Milk samples were analyzed for their composition, including fatty acids, casein profile, fat globule size, and color, and were sterilized to evaluate milk heat stability. Results: There were no significant differences between 0% and 5% CG treatments infeed. Increasing CG supplementation from 0% to 5% increased milk yield from $2.38{\pm}0.12$ to $2.64{\pm}0.23kg/goat/d$. In addition, milk samples from 5% CG treatment had the highest total solids, fat content and lactose content, and largest fat globule size. Increasing CG to 10% resulted in a decrease in milk fat. After sterilizing at $116^{\circ}C$, $F_0=3min$, goat milk samples from 5% CG treatment had slightly higher sediment content and comparatively higher degree of browning. Conclusion: Considering milk yield, milk fat content and quality of sterilized milk, 5% CG supplementation in a total mixed ration has a potential for implementation in dairy goats.

Objectives: The objective of this study was to explore the anti-obesity effect of Cydonia oblonga Miller fruit extract (COME) and to compare its anti-obesity efficacy with Garcinia cambogia extract (GCE) in diet-induced obese mice. Methods: Five-week-old male C57BL/6 were allocated into four groups: control diet (CD), high-fat diet (HFD), HFD + 400 mg/kg body weight (BW)/day COME (H+C), or HFD + 400 mg/kg BW/day GCE (H+G) groups. COME or GCE was administered once a day by oral gavage for eight weeks. Body weight, body fat percentage, fat weight, and biochemical parameters in serum were measured. The expressions of transcription factors and their target genes in epididymal adipose tissues were analyzed by reverse transcription polymerase chain reaction. Results: COME reduced body weight, weight gain, body fat percentage, total white adipose tissue weight, adipocyte size, and serum levels of insulin and leptin in high-fat diet-induced obese C57BL/6 mice. COME suppressed the mRNA expressions of CCAAT/enhancer binding proteinα, peroxisome proliferator-activated receptorγ, sterol-regulatory element-binding protein-1c, fatty acid synthase, and adipocyte protein 2 and increased carnitine palmitoyl transferase 1 mRNA expression in epidydimal adipose tissues. The anti-obesity efficacy of COME was found to be similar to that of GCE at the same dose. However, COME more effectively decreased adipose tissue weights, epididymal adipocyte size, serum insulin and leptin compared to GCE. Conclusions: These results demonstrated that COME is not toxic and exhibits anti-obesity efficacy at a level similar to that of GCE, suggesting that COME may be applicable as an anti-obesity agent.

The current study investigated the anti-obesity effect of Cissus quadrangularsis extracts (CQR-300) and its molecular action mechanism on obese mice induced high-fat diet (HFD). To induce the obesity, mice were fed a HFD for 6 weeks and then fed HFD only or HFD with CQR-300 at 50 and 200 mg/kg. Then, body weight gain and white adipose tissue weights were measured. We investigated the reduction in body fat and the regulation of fatty acid synthesis was measured by dual energy X-ray absorptiometry and real-time PCR with Western blot, respectively. In vitro study, CQR-300 inhibited pancreatic lipase activity. The CQR-300 treatment was significantly decreased the body weight gain and adipocytes size as well as white adipose tissues weights in HFD-induced obese mice. Furthermore, CQR-300 reduced the body fat and fat mass with regulating of adipose tissue hormones as leptin. Treatment with 50 mg/kg CQR-300 showed effectively lower expression levels of adipogenesis/lipogenesis related genes and proteins such as CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$), peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$), Sterol regulatory element binding protein-1c (SREBP-1c), and fatty acid synthase (FAS) in white adipose tissue (WAT) as compared with the HFD fed only mice. These results suggest that the CQR-300 has an anti-obesity effect via inhibition of lipase activity, decrease the body fat mass by regulating the adipogenesis and lipogenesis related genes and proteins in epididymal adipose tissue with evaluate body fat reduce in the HFD-induced obese mice.

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.
