Objectives : The purpose of this study was to investigate the effects of Polygoni Multiflori Radix Water Extract (PM) on the production of inflammatory mediators in RAW 264.7 mouse macrophages induced by lipopolysaccharide (LPS). Method : We examined effect of PM Extract on the cell viability of RAW 264.7 cells. Futhermore, we investigated anti-inflammatory effect of PM Extract by the production of proinflammatory cytokines such as NO, intracellular calcium, interleukin(IL)-$1{\alpha}$, IL-3, IL-$1{\beta}$, IL-6, interferon inducible protein-10(IP-10), keratinocyte-derived chemokine(KC) and vascular endothelial growth factor(VEGF). Result : No significant changes have been found in the mouse macrophge cell viability by the PM Extract at the concentration of 25, 50, 100 and $200{\mu}g/mL$. The water extract of PM significantly inhibited the production of NO and intracellular calcium in the LPS-induced macrophages at the concentration of 25, 50, 100 and $200{\mu}g/mL$. The water extract of PM significantly inhibited the production of IL-$1{\alpha}$, IL-${\beta}$, IL-3, IP-10, KC, VEGF in the LPS-induced macrophages at the concentration of 50, 100, and $200{\mu}g/mL$; IL-6 at the concentration of 100 and $200{\mu}g/mL$ ; and IL-17 at $200{\mu}g/mL$. Conclusion : The water extract of PM significantly inhibited the production of NO, intracellular calcium, IL-$1{\alpha}$, IL-3, IL-${\beta}$, IP-10, KC, VEGF at the concentration of 50 ㎍/mL or higher in the LPS-induced macrophages with no changes in the cell viability of them. These results suggest that water extract of Polygoni Multiflori Radix has anti-inflammatory effect regulating the production of proinflammatory cytokines in the LPS-induced macrophages.

Objectives: Boeum-jeon (BEJ) is a herbal formula composed 8 Korean medicinal herbs and is traditionally used to treat inflammatory diseases. In this study, the authors tried to confirm the antioxidant efficacy of BEJ and its anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Methods: In this experiment, results of BEJ on the following two were measured as follows: (1) Antioxidant effects was measured by DPPH Radical scavenging Activity, ABTS Radical scavenging Activity. (2) Anti-Inflammatory effects were evaluated by the production amount of ROS, NO, Cytokine (PGE2, IL-1β, IL-6, TNF-α), COX-2, iNOS, TNF-α, IL-1β, IL-6, HO-1, NQO1 (the previous seven are "mRNA Expression"), COX-2, iNOS, TNF-α, IL-1β, IL-6, HO-1, NQO1, NRF2 (the previous eight are "Protein Expression") ERK, JNK, p38 (the previous three are "Protein Phosphorylation") in LPS-stimulated RAW 264.7 cells. Results: The experimental measurement results are as follows: (1) DPPH Radical scavenging Activity, ABTS Radical scavenging Activity increased in a concentration -dependent manner in the BEJ-treated group. (2) As a result of measuring anti-inflammatory efficacy, the production of ROS, NO, and Cytokine (PGE2, TNF-α, IL-1β, IL-6) in the BEJ-administered group was significantly reduced compared to the control group. (3) Among mRNA Expression levels, COX-2, iNOS, IL-1β, IL-6 and TNF-α was significantly decreased in a concentration-dependent manner than in the control group, and HO-1 and NQO1 were significantly increased in a concentration -dependent manner than in the control group. (4) Among the Protein Expression levels, COX-2, iNOS, IL-1β, IL-6 and TNF-α was significantly decreased in a concentration -dependent manner compared to the control group, and HO-1, NQO1 and NRF2 was significantly increased in a concentration-dependent manner compared to the control group. (5) As a result of Protein Phosphorylation, ERK, p38 and JNK was significantly decreased compared to the control group in a concentration-dependent manner. Conclusions: Boeum-jeon has been experimentally confirmed to have antioxidant and anti-inflammatory effects, and if the evidence for efficacy is reinforced through further studies such as in vivo studies and clinical trials in the future, it can be effectively used to treat various inflammatory diseases such as bladder inflammation and chronic pelvic inflammation.

Purpose: Globular adiponectin (gAd) is a type of adipocytokine, which is mainly produced by adipose tissue. It has been reported that gAd acts as a pro- as well as an anti-inflammatory factor. Interleukin (IL)-6 and IL-8 are pro-inflammatory cytokines. To investigate the role of gAd on periodontal tissues, the expression of adiponectin receptor 1 (AdipoR1) and the effect of gAd on the expression of IL-6 and IL-8 were investigated in periodontal ligament (PDL) and gingival fibroblasts. Methods: PDL and gingival fibroblasts were cultured from human periodontal tissues. gAd derived from Escherichia coli and murine myeloma cells were used. The expression of AdipoR1 was estimated by reverse transcription-polymerase chain reaction and western blot The expression of cytokines was measured by enzyme-linked immunosorbent assay. Results: PDL and gingival fibroblasts expressed both mRNA and protein of AdipoR1. gAd derived from E. coli increased the production of IL-6 and IL-8, but polymyxin B, an inhibitor of lipopolysaccharide (LPS), inhibited IL-6 and IL-8 production induced by gAd in both types of cells. gAd derived from murine myeloma cells did not induce IL-6 and IL-8 production in those cells. gAd derived from E. coli contained higher levels of LPS than gAd derived from murine myeloma cells. LPS increased production of IL-6 and IL-8 in PDL and gingival fibroblasts, but pretreatment of cells with gAd derived from murine myeloma cells did not inhibit LPS-induced IL-6 and IL-8 expression. Conclusions: Our results suggest that PDL and gingival fibroblasts express AdipoR1 and that gAd does not act as a modulator of IL-6 and IL-8 expression in PDL and gingival fibroblasts.

This study was conducted to test the efficacy of plum (Prunus mume) and red ginseng (Panax ginseng C.A Meyer) marc as stress inhibitors under heat stress and lipopolysaccharide (LPS) challenge in broilers by investigating their effects on blood biochemical parameters, immunoglobulin concentration and splenic cytokine mRNA expressions. A total of one hundred ninety-two 1-d-old male broiler chicks (Ross 308) were divided into 2 stress conditions (heat and LPS) experiments. Each experiment was divided into 4 treatment groups with 8 replicates of 3 birds in each group. NC (negative control, no immune substances), PC (positive control, 25 ppm ${\beta}$-glucan), PM (1% plum marc) and RGM (3% red ginseng marc) treatments were administered with respective substance through water supplementation. During heat stress, The Ca/Mg ratio in PM and RGM was significantly decreased in comparison with that of NC (P<0.05). The immunoglobulin M was significantly lower in PM than in NC (P<0.05). Expression patterns of splenic cytokine mRNAs (IL-1, IL-2 and IL-6) were similar over the treatment. Expression rates of IL-1 and IL-2 in PM were significantly decreased in comparison with NC. Also, expression rates of IL-1, IL-2 and IL-6 were significantly lower in RGM than in NC (P<0.05). In conclusion, the dietary supplementation of plum and red ginseng marc improved coping ability to heat stress by preventing Ca/Mg ratio increment and by inhibiting inflammatory response in broiler chicks. However, it is necessary to determine optimal dietary level of red ginseng marc for improving growth performances in broiler chickens. These results suggest the possibility that plum and red ginseng marc could be used as the stress inhibitor under heat stress and inflammatory response in broiler chicks.

The purpose of this research is to evaluate the effect of Mahaenggamseok-tang-gagambang (MGTG) on airway hyper- responsiveness (AHR), immune cells, cytokines and lung tissue in OVA-induced asthmatic mice. C578L/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (3times a week) for asthma sensitization and challenge. Two experimental groups were treated with different concentrations of MGTG (400 mg/kg and 200 mg/kg) extract and cyclosporin A (10 mg/kg) for the later 8 weeks. Enhanced pause (Penh) levels were measured by whole body plethysmography. Immune cells were analyzed by flow cytometer in peripheral blood monocyte cell (PBMC) and lung cells. The IL-1b, IL-12, IFN-${\gamma}$, OVA-lgE, IL-4, IL-5, TNF-${\alpha}$ were analyzed by ELISA kit in serum and splenocyte+a-cCDS/a-CD28. Enhanced pause (Penh) levels of the MGTG groups (400 mg/kg and 200 mg/kg) were decreased significantly compared with that of control group. The numbers of MGTG groups (400 mg/kg and 200 mg/kg) on lung total cells were decreased significantly compared with that of control group. The numbers of MGTG groups (400 mg/kg and 200 mg/kg) on $CD3^+/CD69^+$, $B220^+/CD22^+$, $B220^+/CD23^+$, $B220^+/lgE^+$, $CCR3^+$ cells were decreased significantly compared with that of control group. The number of MGTG group (400 mg/kg) on $CD3^+/CD49b^+$ cells was decreased significantly compared with that of control group. The level of MGTG groups (400 mg/kg and 200 mg/kg) on IL-4, IL-5, IL-12, TNF-${\alpha}$, OVA-lgE were decreased significantly compared with that of control group. The level of MGTG group (400 mg/kg) on IL-1b, IL-1S, OVA-lgE were decreased significantly compared with that of control group. These results demonstrate that MGTG could be a desirable alternative therapy for allergic asthma by inhibiting the expression of immune cells, the activation of inflammatory mediator.

Objective: The goal of this study was to determine the anti-asthma mechanism of SF on TNF-${\alpha}$ induced activation on A549 (human type II-like epithelial) cells. Using oligonucleotide microarray, we sought to establish the molecular mechanism of the protective effects of SF on A549 cells. Material & Methods : Cells were cultured in three different conditions: 1) negative control group was cultured in normal condition of DMEM, 2) positive control group was activated with TNF-${\alpha}$, IL-4. and IL-1${\beta}$, and 3) SF treated group was previously treated with 0.1${\mu}g/ml$ SF after TNF-${\alpha}$, IL-4. and IL-1 activation. Cells of positive control and SF treated groups were cultured for 30 min, 1hr, 3hr and 6hr. Results : The comparative analysis of the gene expression profile revealed that proinflammatory cytokines such as IL1F8, IL1F9, IL1R1. IL1RN, IL1RAPL1, IL8, TNFRSF4, TNFSF10c, TNFSF13, TRAF5, and TRAF7 and inflammation-related genes including MMP2, MMP11, MMP14, MMP15, MMP16, MMP19, MMP25, and MMP27 were down regulated with SF treatment. Cell adhesion molecule genes such as ITGB1, ITGBL1, selectin P ligand, selectin E, ICAM2, ICAM3, VCAM1, PECAM, FCER1G and MMP28 genes were also down-regulated in SF treated A549 cells. Conclusion : These results suggest that the anti-asthmatic effects of SF could be mediated by regulating specific genes related with cell adhesion, proinflammatory cytokine and inflammation-related genes in A549 cells.

Interleukin-10 (IL-10) is a homodimeric protein with a wide spectrum of anti-inflammatory and immune activities. It inhibits cytokine production and expression of immune surface molecules in various cell types. The transgenic mice carrying the human IL-10 gene in conjunction with the bovine $\beta$-casein promoter produced the human IL-10 in milk during lactation. Transgenic mice were generated using a standard method as described previously. To screen transgenic mice, PCR was carried out using chromosomal DNA extracted from tail or toe tissues with a primer set. In this study, stability of germ line transmission and expression of IL-10 gene integrated into host chromosome were monitored up to generation F15 of a transgenic line. When female mouse of generation F9 was crossbred with normal male, generation F9 to F15 mice showed similar transmission rates (66.0$\pm$20.13%, 61.5$\pm$16.66%, 41.1$\pm$8.40%, 40.7$\pm$20.34%, 61.3$\pm$10.75%, 49.2$\pm$18.82%, and 43.8$\pm$25.91%, respectively), implying that the IL-10 gene can be transmitted stably up to long term generation in the transgenic mice. For ELISA analysis, IL-10 expression levels were determined with an hIL-10 ELISA and a mIL-10 ELISA kit in accordance with the supplier's protocol. Expression levels of human IL-10 from milk of generation F9 to F13 mice were 3.6$\pm$1.20 mg/ml, 4.2$\pm$0.93 mg/ml, 5.7$\pm$1.46 mg/ml, 6.3$\pm$3.46 mg/ml, and 6.8$\pm$4.52 mg/ml, respectively. These expression levels are higher than in generation F1 (1.6 mg/ml) mice. We concluded that transgenic mice faithfully passed the transgene on their progeny and successively secreted target proteins into their milk through several generations, although there was a little fluctuation in the transmission frequency and expression level between the generations.

To elucidate the molecular mechanisms of autoimmune inflammation in the central nervous system, we examined the expression and localization of STAT1, STAT3, STAT4 and STAT6 molecules during experimental autoimmune encephalomyelitis (EAE) by competitive PCR. In the present study, we quantitated IL-4 and IL-12 p40 mRNA by competitive PCR in the CNS during EAE. IL-4 mRNA was found at early and peak stages. On the other hand, the IL-12 p40 mRNA level reached maximal levels at the peak stage and still found at the recovery stage of the disease. We examined the kinetics of STAT mRNA in the CNS during EAE and demonstrated that STAT1 and STAT4 mRNA reached a maximal level at the peak stage of EAE, whereas STAT3 mRNA level increased gradually to the recovery stage. STAT6 mRNA increased rapidly at the early stage followed by gradual decrease till the recovery stage. Taken together, these findings suggest that STAT4 which was probably activated by IL-12 plays a pro-inflammatory role and that STAT3 which was activated throughout the disease course seems to serve as a transducer of anti-inflammatory signals.

Blocking of IL-6 has been postulated to be an effective therapy in the pathogenesis of several inflammatory diseases. The current study was performed to examine the potential effects of alkamides isolated from P. longum and P. nigrum on IL-6 induced Stat3 activation and identify the structure-activity relationship of these alkamides in human hepatoma cells. Among 10 alkamides isolated from P. longum and P. nigrum, compounds 6, 7 and 9 were identified as strong inhibitors of IL-6 action, which inhibit IL-6 induced Stat3-dependent luciferase activities. These inhibitory activities were positively influenced by the presence of piperidine moiety.

Morus alba L., known as white mulberry, is a medicinal plant belongs to family Moraceae. It has long been used commonly in Ayurvedic for the treatment of lung-heat, cough, asthma, hematemesis, dropsy and hypertension. In the present study, seven prenylated flavonoids, along with four benzofuran compounds were isolated by means of repeated column chromatography. The structures of the known compounds were identified as kuwanon G (1), kuwanon E (2), kuwanon T (3), morusin (4), sanggenon A (5), sanggenon M (6), sanggenol A (7), moracin R (8), mulberofuran G (9), mulberofuran A (10) and mulberofuran B (11), by comparing their spectroscopic data with those reported in the literature. For these isolates, containing trace compounds, the inhibitory activity against IL-6 production in $TNF-{\alpha}$ stimulated MG-63 cells was examined. All isolated compounds (1 - 11) showed excellent inhibitory activity against IL-6 production in $TNF-{\alpha}$ stimulated MG-63 cells. Especially this study is first time to report that sanggenon A (5), sanggenon M (6), sanggenol A (7), mulberofuran G (9), mulberofuran A (10) and mulberofuran B (11) showed the inhibitory activity of IL-6 production. Our study suggested the possibility of anti-inflammatory regulation by compounds (1 - 11) isolated from M. alba.
