Objectives : The purpose of this study was find out the therapeutic effects of its exclusive use on the rat with allergic rhinitis. Materials and Methods : Thirty Sprague-Dawley rats were divided into three group : normal group, control group and sample group. To induce the allergic rhinitis in control group and sample group, rats were sensitized intraperitoneally with 0.1% ovalumin solution 3 times at intervals of 1 week. Then intranasal sensitization was performed by diffusing 0.1% ovalumin solution 3 times at intervals of 2 days. After that time, rats in the sample group were administered by $Yonghyang$($LI_{20}$) subcutaneously to treat the inflammation. Results : 1. The anti-oxidant effects of $Hwangryunhaedok-tang$ extract was dose-dependantly increased. 2. The RAW 264.7 cells were treated with LPS for 1 hours prior to the addition of indicated concentrations ($0.4,-1.0mg/m{\ell}$) of HHT, and the cells were further incubated for 24 hours. The LPS-induced iNOS mRNA expression and NO production were dose-dependantly decreased in HHT treated RAW 264.7 cells. 3. The number of eosinophil in HP noticeably decreased than CON and this decrease had probability. The infiltration of eosinophil in HP noticeably decreased than CON. 4. The damaged mucosa as disruption of cilia in respiratory cell and vacant mucose secreting cell were increased CON, but HP same as normal configuration. Decrease of PAS positive cell were shown in CON, but goblet cell occupied with neutral mucous were shown in HP. Decrease of mucosal stress(HSP70). Decrease of perennial sign(PPAR-${\gamma}$). Decrease of icthing and sneezing intricate neurotransmitter-(substance P). 5. The anti-inflammation of HHT pharmacopuncture for AR caused mucosa comes to result as belows. Decrease of pre-inflammation cytokine(TNF-${\alpha}$). Decrease of transcription factor (NF-${\kappa}B$ p65). Decrease of transcription factor inhibitor(p-$I{\kappa}B$). Decrease of inflammation cytokine(iNOS). Conclusions : The results may suggest that administration treatment using $Hwangryunhaedok-tang$ pharmacopucnture decreases the inflammatory response on an animal model with allergic rhinitis.

This study was aimed to characterize osteogenic potential of rat bone marrow stromal cells (BMSC) isolated with standard flushing method and investigate the plasticity of transdifferentiation between osteoblastic and adipocytic lineage of cultured BMSC. Unlike aspiration method in human, rat bone marrow was extracted by means of irrigation with culture media that elevates the possibility of co-extraction of committed osteoprogenitor, or preosteoblast or other progenitor cells of several types present inside bone marrow. The cultured stromal cells showed high ALP activity which is representative marker of osteoblast without any treatment. Osteogenic inducers such as Dex and BMP-2 were examined for the evaluation of their effect on osteogenic and adipocytic differentiation of stromal cells, because they function as osteoinductive agent in stromal cells, but simultaneously induce adipogenic differentiation. Osteogenic differentiation was evaluated by measuring alkaline phosphatase activity or mRNA expression of osteoblast markers such as osteopontin, bone sialoprotein, collagen type I and CbfaI, and in vitro matrix mineralization by von Kossa staining. Oil red staining method was used to detect adipocyte and adipocytic marker, aP2 and $PPAR{\gamma}2$ expression was examined using RT-PCR. It can be supposed that irrigation procedure resulted in high portion of already differentiation-committed osteoprogenitor cell showing elevated ALP activity and strong mineralization only under the supplement of $100{\mu}M$ ascorbic 2-phosphate and 10mM ${\beta}$-glycerophosphate without any treatment of osteogenic inducers such as Dex and BMP-2. Dex and BMP-2 seemed to transdifferentiate osteoprogenitor cells having high ALP activity into adipocytes temporarily, but continuous treatment redifferentiated into osteoblast and developed in vitro matrix mineralization. This property must be considered either in tissue engineering for bone regeneration, or in research of characterization of osteogenic differentiation, with rat BMSC isolated by the standard irrigation method.

Obesity, the world's leading metabolic disease, is a serious health problem in both industrialized and developing countries. Natural substances are of great interest in preventative medicine, especially in the field of metabolic syndromes-from insulin resistance to obesity and diabetes. In the present study, we investigated the effect of A. pullulans SM-2001 Extract (Polycan^®) on the adipocyte differentiation of 3T3-L1 preadipocytes and the anti-obesity effect of 3T3-L1 adipocytes. Although β-glucan has been found to have health benefits in the regulation of the immune system and blood cholesterol levels, its role in obesity has not been fully investigated. Polycan^® suppressed lipid accumulation and glycerol-3-phosphate dehydrogenase (GPDH) activity without affecting cell viability in 3T3-L1 preadipocytes and adipocytes. Polycan^® also inhibited cellular lipid accumulation through down-regulation of transcription factors, such as PPARγ and C/EBPα, and induced dose-dependent phosphorylation of AMP-activated protein kinase (AMPK)-a cellular energy sensor-while the total AMPK protein content remained unchanged. Taken together, this shows that the activation of AMPK by Polycan^® in adipocytes plays a critical role in Polycan^®-induced inhibition of adipocyte differentiation. Our results show that Polycan^® has an anti-obesity action in vitro, suggesting a potential novel preventative agent for obesity and other metabolic diseases.

Objective : This experimental study was designed to determine the effects of BPT on obesity in vivo and in vitro. Methods : in vitro, BPTn extracts of various concentration(50, 100, 200 ${\mu}g/m{\ell}$) were added in 3T3-L1 cell. Adipocyte differentiation was measured by Oil Red O staining and Morphological examination. The expression of $C/EBP{\alpha}$ and $PPAR{\gamma}$ receptor was measured by western blot assay and RT-PCR in vivo, Rats were orally administered BPT daily for consecutive four weeks before poloxamer-407 induced hyperlipidemic state. The rats were sacrificed 24 hrs later for poloxamer-407 treated and then serum triglyceride, total cholesterol were measured ; Rats were orally administered BPT daily for consecutive four weeks before triton WR-1339 induced hyperlipidemic state. The rats were sacrificed 40 hrs later for triton WR-1339 treated and then serum triglyceride, total cholesterol were measured ; Rats with obesity were induced by the high fat-diet for six weeks and then serum triglyceride, total cholesterol, LDL-cholesterol, triglyceride, HDL-cholesterol, hydroxy radical, superoxide dismuatse activity were measured. Results : In vitro, The 3T3-L1 cells' differentiation was significantly decreased by BPT. The expression of $C/EBP{\alpha}$ and $C/EBP{\beta}$ was decreased by BPT. In vivo, BPT significantly reduced serum triglyceride, total cholesterol contents in poloxamer-407 treated rat. BPT significantly reduced serum triglyceride contents in Triton WR-1339 treated rat. Total cholesterol also reduced but did not show a significant change. BPT significantly reduced body weight gain of rat and adipose tissue mass of rats and serum triglyceride, LDL-cholesterol contents and significantly increased HDL-cholesterol, HTR(HDL-cholesterol/Total-cholesterol) in rats with obesity induced by the high fat-diet. BPT reduced blood lipid peroxide, hydroxy radical and increased superoxide dismuatse(SOD) activity.

Anti-diabetic effect of Platycodi radix (PR) extract fractions was determined if vitro by investigating insulin-like action, insulin sensitizing action, glucose-stimulated insulin secretion, gene expression related to ${\beta}-cell$ function and mass, and ${\alpha}$-glucoamylase suppressing action. Insulin-like activity was not promoted by the treatment of PR methanol factions in 373-L1 fibroblast. However, treatment with 0, 20 and 100% PR methanol fractions along with 1 ng/mL insulin increased insulin-stimulated glucose uptake in 373-L1 adipocytes. In addition, the treatment of 0% and 100% methanol fractions along with differentiation inducers significantly increased the differentiation of 373-L1 fibroblasts to adipocytes. These fractions may contain insulin sensitizer. The 20%, 80% and 100% methanol fractions enhanced glucose-stimulated insulin secretion in Min6 cells, insulin secreting cell line. This was related to the mechanism to promote glucose sensing and ${\beta}-cell$ proliferation, which was regulated by the induction of IRS-2, glucokinase and PDX-1 genes. As expected, 20, 80 and 100% methanol fractions increased mRNA levels of IRS-2, glucokinase and PDX-1 genes. However, PR fractions did not affect the ${\alpha}-glucoamylase$ activity in vitro. These data suggested that PR extract fractions have anti-diabetic actions through improving insulin sensitization, glucose-stimulated insulin secretion, and ${\beta}-cell$ proliferation. Therefore, PR extracts can be beneficial for anti-diabetic treatment in lean diabetic patients.

The purpose of this study was to evaluate anti-obesity activity of Cirsium setidens Nakai test material (CNTM) in 3T3-L1 adipocytes and obese C57BL/6J mice fed with a high-fat diet using various obesity-related in vitro experiments. During adipocyte differentiation, CNTM significantly inhibited lipid accumulation and ROS production compared to controls. To evaluate whether CNTM could exert glycerol release effects on mature 3T3-L1 adipocytes, we treated cells with various concentrations of CNTM for 1 h. Treatment of mature adipocytes with $160-320{\mu}g/mL$ of CNTM increased the release of glycerol, but not in a significant dose-dependent manner. Anti-adipogenic and anti-lipogenic effects of CNTM seemed to be mediated by the inhibition of $PPAR{\gamma}$ and $C/EBP{\alpha}$. Moreover, CNTM stimulated fatty acid oxidation in an AMPK-dependent manner. CNTM-treated groups of C57BL/6J mice showed reduced body weights and adipose tissue weight with improving serum lipid profiles and adiponectin protein expression in obese C57BL/6J mice fed with a high-fat diet. These results suggest that CNTM might have anti-obesity effect on adipogenesis and lipid metabolism in vitro and in vivo. This presents the possibility of developing a treatment for obesity using nontoxic natural resources.

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.

In aquatic invertebrates, particularly marine gastropods, organotin compounds induce irreversible sexual abnormality in females, which is termed imposex, at very low concentrations. Organotin compounds are agonists for nuclear receptors such as RXRs and $PPAR{\gamma}$. However, the imposex phenomenon has not been reported to act as an antagonist on estrogen receptors in other species, including vertebrates and invertebrates. In order to gain insights into the antagonistic activity of organotin compounds on estrogen receptors (ERs), we examined the inhibitive effect of these compounds on estradiol-dependent ${\beta}$-galactosidase activity using the yeast two-hybrid detection system consisting of a combination of the human estrogen receptor ($hER{\beta}$) ligand-binding domain and the co-activator steroid receptor co-activator-1 (SRC1). Tributyltin-hydroxide (TBT-OH) and triphenyltin-chlorine (TPT-Cl) exhibited an inhibitive effect on $E_2$-dependent transcriptional activity, similar to antagonistic chemicals such as 4-hydroxytamoxifen (OHT) or ICI 182,780, at a very low concentration of $10^{-14}$ M TBT or $10^{-10}$ M TPT, respectively. The yeast growth and transcriptional activity with transcriptional factor GAL4 did not exhibit any effect at the tested concentration of TBT or TPT. Moreover, the yeast two-hybrid system using the interaction between p53 and the T antigen of SV40 large did not describe any effect at the tested concentration of OHT or ICI 182,780. However, the interaction between p53 and T antigen was inhibited at a TBT or TPT concentration of $10^{-9}$ M, respectively. These results indicate that TBT and TPT act as inhibitors of ER-dependent reporter gene transcriptional activation and of the interaction between $hER{\beta}$ LBD and the co-activator SRC1 in the yeast two-hybrid system. Consequently, our data could partly explain the occurrence of organotin compound-induced imposex on the endocrine system of mammals, including humans.

Methods and materials : Each of 6 rats was divided into a normal diet, HFD, MH, and FMH. We fed a HFD group of rats a high fat diet and administered normal saline for 8 weeks. And we fed an experimental group of rats a high fat diet and administered an extract of Ephedra sinica and fermentated Ephedra sinica for 8 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. Ephedra sinica and fermentated Ephedra sinica was examined in effects of 3T3 L1 cell viability, lipid and glycometabolism, rats' behavior and state-trait anxiety. Results : 1. Ephedra sinica and fermentated Ephedra sinica didn't induce cytotoxicity at 3L3 L1 cell. 2. Fermentated Ephedra sinica by Lactococcus confusus inhibit $PPAR-{\gamma}$ activation and promote $TNF-{\alpha}$ activation. 3. In MH and FMH group, the body weight and FER decrease occured significantly than in HFD group. 4. No side effect of Ephedra sinica appeared in FMH group, so fermentated Ephedra sinica have a capacity of anti-anxiety. 5. Serum total cholesterol, triglyceride, HDL-cholesterol and creatine of HFD+Ephedra sinica, HFD+LO group were decreased compared with that of HFD group. Decreasing rates of sample group was significant(p<0.05). 6. In both MH and FMH group serum HDL was increased(P>0.05). 7. In MH group only TG was decreased, but in FMH group total cholesterol, TG, and glucose were decreased(P>0.05). Conclusions : Fermentated Ephedra sinica by Lactococcus confusus was superior to Ephedra sinica in capacity of anti-obesity. Further fermentated Ephedra sinica have no Ephedra sinica's side effect.
