Aim: Pendulous monkshood root is traditionally used for the treatment of several inflammatory pathologies such as rheumatisms, wounds, pain and tumors in China. In this study, the anti-inflammatory and anticancer activities and the mechanism of crude ethanol extract of pendulous monkshood root (EPMR) were evaluated and investigated in vitro. Materials and Methods: The cytotoxic effects of EPMR on different tumor cell lines were determined by the MTT method. Cell apoptosis and cell nucleus morphology were assessed by Hoechst 33258 staining. Moreover, nitric oxide (NO) levels and intracellular oxidative stress in peritoneal macrophages were determined to further elucidate mechanisms of action. Results: The data showed that EPMR could produce significant dose-dependent toxicity on three kinds of tumor cells. Furthermore, EPMR displayed obvious anti-inflammatory effects on LPS-induced mouse peritoneal macrophages at the dosage of 4 - 200 ${\mu}g/mL$. The results demonstrated the therapeutic potential of Pendulous Monkshood Root on cancer and inflammatory diseases. Conclusion: Our results indicate that EPMR has anti-inflammatory and anticancer properties, suggesting that pendulous monkshood root may be a useful anti-tumor and anti-inflammatory reagent in the clinic.

Endothelial cell protein C receptor (EPCR) plays important roles in blood coagulation and inflammation. EPCR activity is markedly changed by ectodomain cleavage and release as the soluble EPCR. EPCR can be shed from the cell surface, which is mediated by tumor necrosis factor-${\alpha}$ converting enzyme (TACE). Oroxylin A (OroA), a major component of Scutellaria baicalensis Georgi, is known to exhibit anti-angiogenic, antiinflammation, and anti-invasive activities. However, little is known about the effects of OroA on EPCR shedding. Data showed that OroA induced potent inhibition of phorbol-12-myristate 13-acetate (PMA), tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and on cecal ligation and puncture (CLP)-induced EPCR shedding through suppression of TACE expression and activity. In addition, treatment with OroA resulted in reduced PMA-stimulated phosphorylation of p38, extracellular regulated kinases (ERK) 1/2, and c-Jun N-terminal kinase (JNK). These results demonstrate the potential of OroA as an anti-sEPCR shedding reagent against PMA and CLP-mediated EPCR shedding.

Previously, we reported that water-extracted Acanthopanax senticasus exhibited anti-meta-static activity by stimulating the immune system. In this study, we fractionated glycoproteins (EN-SP) from the soluble protein layer (GF-AS) of A. senticasus and determined their basic chemical properties. We also investigated the anti-tumor and immunostimulating activities of the fractionated glycoprotein, EN-SP. We found that intravenous (i.v.) administration of GF-AS dramatically inhibited metastasis of colon26-M3.1 carcinoma cells to the lung in a dose-dependent manner. In vitro analysis showed GF-AS to enhance the proliferation of splenocytes. GF-AS also stimulated peritoneal macrophage, which was followed by the production of various cytokines such as IL-1$\beta$, TNF-$\alpha$, IL-12 and IFN-${\gamma}$. Furthermore, the production of these cytokines was partially blocked when peritoneal macrophage was cultured with the polyclonal antibodies against GF-AS. The depletion of NK cells by rabbit anti-asialo GM1 serum partly abolished the inhibitory effect of GF-AS on lung metastasis of colon26-M3.1 cells. Using gel filtration, EN-SP, an active glycoprotein fraction, is isolated from GF-AS. While both GF-AS and EN-SP stimulated the proliferatation of splenocytes of normal mice, EN-SP showed higher anti-metastatic activity and more potently stimulated the proliferation of splenocytes compared to GF-AS. These results suggest the use of EN-SP, the fractionated glycoprotein from A. senticasus, can be used as a therapeutical reagent to prevent or inhibit tumor metastasis.

The urushiol-ethanol corpuscle of 320 nM in average particle size was prepared and concentrated by ultra homogenization and centrifugation. The cytotoxic profiles of this particle for use as anti-tumor agent have been evaluated in vitro in cultures of human fibroblasts (MRC-9) and celvical carcinoma cells (CUMC-3). The cytotoxicty assays revealed that the inhibitor effect of $10^{-5}$ M urushiol-ethanol particle on the growth of MRC-9 was hardly detected, while CUMC-3 cells exhibited over 50% of growth inhibition under the same conditions. In addition, a clear multiple-unit ladder pater of apoptotic DNA was observed for the urushiol treated CUMC-3 cells. Thus, the results indicated that urushiol inhibited growth of celvical carcinoma cells by inducing apoptosis, which is a mechanism observed with other typical antitumor agents.

Objectives : We determined the anti-inflammatory activity of KCNS-001 that is a herbal formula including 6 medicinal plants and that are used to mitigate atopic dermatitis in oriental medicine. Methods : To evaluate anti-inflammatory effect of KCNS-001, we measured the production of reactive oxygen species (ROS), nitric oxide (NO) and cyclooxygenase-2 (COX-2) in LPS-activated Raw 264.7 cells. Cell viability was determined by MTT assay. The concentrations of ROS and relative level of NO were measured with DPPH assay and Griess reagent, respectively. COX-2 and TNF-$\alpha$ were detected by enzyme immuno assay (EIA) and enzyme-linked immunosorbent assay (ELISA). Results : ROS and NO production were reduced by KCNS-001 in a dose-dependent manner. KCNS-001 significantly inhibited activity of COX-2 and suppressed the release of tumor necrosis factor-alpha (TNF-$\alpha$). Conclusions : These results indicate that the KCNS-001 may have an anti-inflammatory agent for the treatment of various inflammatory disease.

Objective : Inflammatory cytokines have a close relationship to insulin dependent diabetes mellitus (IDDM). The inhibitory effect of Smilacis Glabrae Rhizoma (SGR) were examined on production of nitric oxide (NO), prostaglandin $E_2$ $(PGE_2)$, synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and NF-${\kappa}$B activation in Raw 264.7 cells. Methods: Raw 264.7 cells were pretreated with SGR(20, 50, 100 ${\mu}g$/ml), and then cultured with lipopolysaccharides (LPS). Cell viability was measured by MTT assay; inhibition of NO, $PGE_2$, and TNF-${\alpha}$ production were measured by Griess reagent and enzyme-linked immunosorbent assay(ELISA). Induction of COX-2 and iNOS were determined by western blotting analysis. Inhibition of NF-${\kappa}$B was measured by immunofluorescence assay (IFA). Results: SGR inactivated NF-${\kappa}$B, and inhibited the production of NO, iNOS, and $PGE_2$. Inhibition of COX-2 and TNF-${\alpha}$ could not be confirmed. Conclusions: From the above result. SGR was found to have an anti-inflammatory effect of inhibition of NO, iNOS, and $PGE_2$ production via inhibition of NF-${\kappa}$B.

Objective : Salvia miltiorrhiza Bunge (Labiatae) (SM), an eminent herbal plant, has been widely used in traditional Chinese medicine for the treatment of vascular diseases such as hypertension. The aim of this study was to determine whether SM inhibits production of nitrite, an index of NO, and proinflammatory cytokines in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages. And this study investigated whether or not SM could reduce tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$)-induced inflammatory response in human vascular aortic smooth muscle cells (HASMC) and umbilical vein endothelial cells (HUVEC). Methods : Cytotoxic activity of SM on RAW 264.7 cells was using 5-(3-caroboxymeth-oxy phenyJ)-2H-tetra-zolium inner salt (MTS) assay. We measured the NO production using Griess Reagent System. Production of Proliflammatory cytokines was measured by Enzyme-Linked Immunosorbent Assay (ELISA). Results : Our results indicated that SM significantly inhibited the LPS-induced NO production accompanied by an attenuation of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), IL-6 and monocyte chemoattractant protein (MCP)-1 formation in macrophages. SM decreased TNF-${\alpha}$-induced IL-8, IL-6 production, and intracellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1 expression. Conclusion : These results indicate that SM has potential as an anti-inflammatory agent.

Objectives : The aim of this study is to investigate the various effects of individual or combined extract of GamiSaengmaeksan (GSS) on cell viability, anti-inflammatory and antioxidant activityMethods : In order to evaluate cytotoxicity, MTT assay was performed. We investigated the levels of proinflammatory cytokines such as tumor necrosis factor (TNF)-α and interleukin (IL)-6 and interleukin (IL)-1β, and nitric oxide(NO) in LPS-induced RAW 264.7 cells to check the effects on anti-inflammatory activity. The level of NO production in RAW 264.7 cells was measured by using Griess reagent. The levels of cytokines and ROS were measured by Luminex and Flow cytometry, respectively.Results : At concentration of 200 ㎍/㎖ GSS, cytotoxicity was observed in RAW 264.7 cells. However, at concentration less than 100 ㎍/㎖ of both combine and individual GSS, cytotoxicity was not observed in Raw 264.7 cells. However, the level of ROS in RAW 264.7 cells were decreased at both extract of 100 ㎍/㎖ GSS. Also, the level of NO in RAW 264.7 cells were decreased from extraction of concentration of 100 ug/ml in GSS and individual-extraction of Liriopis Tuber, White Ginseng and Glycyrrhizae Radix. In addition, productions of pro-inflammatory cytokines (TNF-α) in LPS-induced RAW 264.7 cells were decreased from extraction of concentration of 10 and 100 (㎍/㎖) in GSS and individual-extraction of Liriopis Tuber.Conclusions : It is concluded that combined extract of GSS appears to be more effective in anti-oxidation and anti-inflammatory effect than those in individual-extraction of GSS. These results may be developed as a raw material for new therapeutics to ease the symptoms related with inflammatory and oxidative stress.

Lysozyme protects us from the ever-present danger of bacterial infection and binds to bacterial lipopolysaccharide (LPS) with high affinity. Beyond its role in the activation of protein C, the endothelial cell protein C receptor (EPCR) plays an important role in the cytoprotective pathway. EPCR can be shed from the cell surface, which is mediated by tumor necrosis factor-α converting enzyme (TACE). However, little is known about the effects of lysozyme on EPCR shedding. We investigated this issue by monitoring the effects of lysozyme on phorbol-12-myristate 13-acetate (PMA)-, tumor necrosis factor (TNF)-α-, interleukin (IL)-1βand cecal ligation and puncture (CLP)-mediated EPCR shedding and underlying mechanism. Data demonstrate that lysozyme induced potent inhibition of PMA-, TNF-α-, IL-1β-, and CLP-induced EPCR shedding. Lysozyme also inhibited the expression and activity of PMA-induced TACE in endothelial cells. These results demonstrate the potential of lysozyme as an anti-EPCR shedding reagent against PMA-mediated and CLP-mediated EPCR shedding.
