To compare the medical efficacy of original Socheongyong-tang with fermented Socheongyong-tang, we've studied the two medicines according to the search for optimal bacteria and optimal conditions, component analysis, assessment of medical efficacy and toxicity, and have the result below. The results were obtained as follows: Considering bacterial growth, $CO_2$ gas emission and pH, we examined that using 3 kinds of bacteria(S. cerevisiae KCTC 7913, L. casei KCTC 3109, L. brevis KCTC 3102) is desirable. There is no main difference in optimum conditions between incubator and shaking incubator. And it is considered that ideal fermentation time is 2 days after vaccination. As the result of componential analysis of before and after fermentation, there's a noticeable decrease of total sugar and protein. But there's no alterations in total phenolics compounds and in total flavonoid compounds that influence on medical effect. The result was interpreted that it can promote the assimilation of herbal decoction after fermentation. As the result of medical efficacy assessment, we can check out that there is more anti-oxidating effects in fermented Socheongyong-tang, whereas anti-inflammatory effects and obesity-preventing effects were favorable in original Socheongyong-tang. And there is no main difference of whitening and COX-2 removing effects between before and after the fermentation. As a result of assessing weight change, hepatotoxicity and nephrotoxicity, we can not notice any unusual difference between before and after the fermentation. According to the results above, it is considered that we checked out the optimal bacteria and optimal conditions, advantages and disadvantages of the medical efficacy of original Socheongyong-tang and fermented Socheongyong-tang. And we suggest that there will have to be a following in-depth and systematic research on this subject in the future.

The purpose of this study was to investigate the anti-obesity and anti-inflammation effect of the cheonggukjang (a soybean paste fermented for only a few days) in diet induced obesity mice. Weight gain was significantly decreased in the mice fed cheonggukjang compared High Fat Diets (HFD). The HFD plus cheonggukjang (CGJ) were also effective in improving the lipid metabolism. The levels of plasma triglyceride, cholesterol, ALT, AST, leptin, glucose, and insulin were significantly lower in CGJ than HFD group (p<0.05). The adiponectin level of CGJ group was significantly increased compared to the HFD group (p<0.05). In the CGJ group, the mRNA expression of adipogenic genes in the liver and adipose tissues, which are transcription factors crucial for adipogenesis, were significantly suppressed (p<0.05). The number of $CD11b^+F4/80^+$ T cells, $Gr-1^{int}CD11b^{high}$ cells, and $Gr-1^{int}CD11b^{high}$ cells were significantly higher in HFD group than CGJ group (p<0.05). The size of adipocyte was significantly reduced in CGJ group compared to HFD group. In addition, the contents of liver lipid droplets were significantly downregulated in the CGJ mice than HFD mice (p<0.05). Collectively, these data suggest the novel function of cheonggukjang in modulating adipogenesis through an immune function-alteration involving downregulation of adipogenic transcription factors and macrophage activation.

This study was to investigated the changes of physiologically active components in germinated brown rice treated with chitosan (CGBR) and its anti-obesity effect in rat fed a high fat diet. Contents of physiologically active compounds such as total phenolic compounds, total dietary fiber, $\gamma$-aminobutyric acid (GABA), and total phytic acid in CGBR were significantly higher than those of traditional germinated brown rice (GBR). Lipase inhibitory activity of CGBR was higher than those of GBR and brown rice (BR). High fat diets containing CGBR, GBR, and BR were administered to three groups of male Sprague-Dawley rats for four weeks. All groups showed no significant difference in body weight, total abdominal fat, and plasma lipid levels. However, CGBR group appeared to have lower body weight gain and total abdominal fat level than other groups fed high fat diets containing GBR and BR. Total cholesterol and LDL-cholesterol contents in plasma of CGBR group were also lower than those of other groups. Thus, new germination method of brown rice using chitosan is a useful process, which utilizes plant defense responses to elevate the production of secondary metabolites and anti-obesity effect.

Objectives : Obesity is caused by the excess accumulation of fat in the body due to energy imbalance, and it causes various diseases. The aim of this study was to investigate an anti-obesity efficacy and an antioxidant activity of water from herbal mixture extract (SM17). Methods : The antioxidant activities were evaluated through radical scavenging assays using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals. To evaluated anti-obesity effect of SM17, we used a high fat diet fed mouse model. The SM17 (150 mg/kg body weight/day, p.o.) was treated every day for 6 weeks to C57BL/6 mice. Body weight and food intake were measured every day. The changes of reactive oxygen species (ROS), alanine aminotransferanse (ALT), aspartate aminotransferase (AST), triglycerids (TG) and total cholesterol (TC) in serum were analyzed after experiment. Also, expression of lipid metabolism related proteins were investigated by western blot analysis. Results : It was effective in antioxidant measurements, SM17 administration inhibited the biomarkers of lipid metaboism in serum and tissues. The administration of SM17 showed a significant reduction of body and tissue weight. Morever, it decreased ROS, ALT, AST, TG and TC in serum, compared with those of the obese mice. Adipogenesis-related protein expressions increased in obese mice compared to normal mice. However, SM17 group exhibited the down-expression of these proteins. Conclusion : A SM17 aqueous extract has a great effect on the stimulation (AMPK) activation, and may have a benefit to reduce a fatty acid metabolism through inhibition of lipid accumulation.

Objectives The purpose of this study was to evaluate anti-obesity effect of Galgeuntang (gegentang) and elucidate the effect of it on gene expression related to obesity. Methods The experiments were performed with the use of Diet-Induced Obese mice. They were grouped NC (normal control), HFD (high fat diet control), GGT (Galgeun-tang (gegentang), 700 mg/kg), ORL (Orlistat, 10 mg/kg). GGT was orally administered for 12 weeks. Body weight was measured every week. Real-time PCR was performed to investigate the effect of GGT on gene expression in liver tissue. Results GGT group and ORL group were reduced in body weight compared with HFD. HFD increased $PPAR{\gamma}$, SREBP-1, Leptin, aP2, FATP1, FAS gene expression compared with NC. GGT increased FATP1 gene expression. But GGT reduced $PPAR{\gamma}$ & FAS gene expression in liver tissue of diet-induced obese mice compared with HFD. Conclusions These results suggest that GGT is supposed to have a certain impact on the treatment of obesity. But more study is needed in the future.

High performance liquid chromatography (HPLC) analysis on the MeOH extract of Ligularia stenocephala leaves identified six caffeoylquinic acids, viz. 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoyl-mucoquinic acid, 3,5-di-O-caffeoylquinic acid, 4,5-di-O-caffeoylquinic acid, 5-O-caffeoylquinic acid, and 3-Ocaffeoylquinic acid using standard compounds, and determined the quantity of each extract. Percentage of total caffeoylquinic acids of the MeOH extract and its BuOH fraction were calculated as $67.83{\pm}3.79%$ and $94.52{\pm}1.84%$, respectively. Since the caffeoylquinic acid-rich MeOH extract exhibited a potent peroxynitrite-scavenging effect in vitro ($IC_{50}=0.87{\pm}0.33\;{\mu}g/ml$ (mean $\pm$ SEM)), the experiment was designed to identify whether or not that extract has an anti-obesity effect on rat obesity induced by high fat diet. Oral administration of the MeOH extract and its BuOH fraction abundant in caffeoylquinic acid decreased the rat body weight to the level of untreated group and decreased abdominal fat pad weight. The atherogenic index and thiobarbituric acid-reactive substance (TBARS) values were restored by treatment, indicating that the caffeoylquinic acid-rich extract probably inhibited hyperlipidemia and oxidative stress caused by high fat diet. These results suggest that L. stenocephala in vegetable form or its caffeoylquinic acid-rich fraction (BuOH fraction) as an agent can be used for treatment or prevention of obesity.

The peel of Citrus sunki exhibits multiple biological activities such as anti-oxidant, anti-inflammation and anti-obesity, but little is known about neurodegeneration-related activities. In this study, we investigated the protective effect of ethanolic extract from both immature and mature Citrus sunki peel on neuronal cell death. Treatment of the neuroblastoma cell line SH-SY5Y with $MPP^+$, an inducer of Parkinson disease model, increased cell death in a dose dependent manner. Increased levels of active caspase-3 and cleaved PARP were detected. Treatment with immature Citrus sunki peel extract significantly reduced $MPP^+$-induced neurotoxicity. Cytoprotection with immature Citrus sunki peel extract was associated with a decrease in caspase-3 activation and PARP cleavage. In contrast, mature Citrus sunki peel extract had no significant effects. These data suggest that immature Citrus sunki peel extract may exert anti-apoptotic effect through the inhibition of caspase-3 signaling pathway on $MPP^+$-induced neuronal cell death.

Ulcerative colitis (UC) is an inflammatory bowel disease and a chronic gastrointestinal disorder. Rubi Fructus (RF), the fruit of Rubus coreanus Miquel, is known to exert several pharmacological effects including anti-oxidative, anti-obesity and anti-inflammatory properties. However, the improving effect and mechanism of RF on intestinal inflammation is not been fully understood. The purpose of this study was to investigate the regulatory effect of RF on dextran sulfate sodium (DSS)-induced colitis in mice. We evaluated the effects of RF on DSS-induced clinical signs by analyzing weight loss and colon length. The inhibitory effects of RF on inflammatory mediators such as prostaglandin E₂ (PGE₂), cyclooxygenase (COX)-2, as well as the activation of nuclear factor-κB (NF-κB), were determined in colitis tissue. Our data indicated that mice treated with DSS showed clinical symptoms of colitis, including weight loss, colon length decrease and diarrhea. However, we observed that RF treatment significantly improved these clinical symptoms of weight loss, colon length decrease and diarrhea induced by DSS. RF inhibited the enhanced levels of COX-2 and PGE₂ caused by DSS. We also showed that the anti-inflammatory mechanism of RF by suppressing the activation of NF-kB in DSS-treated colon tissues. Collectively, the findings of this study indicate the prospect of developing new drugs from RF for UC treatment.
