This study was performed to evaluate anti-thrombotic activities and anti-inflammatory effects of ChungyeolHaedogHwaeoTang water extract(CHHT). The results were summarized as follows. In experiment of anti-thrombotic effect; 1. CHHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group, and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 37.5%). 2. CHHT increased platelet number significantly, and also CHHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; 3. CHHT inhibited $IL-1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent degree as compared with the control of group in RAW 264.7 cell line. 4. CHHT inhibited $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production in spleen tissue, and also decreased $IL-1{\beta}$, and IL-6 production in liver tissue, but increased TNF-${\alpha}$ production in liver tissue of acute inflammation-induced Balb/c mice. 5. CHHT increased survival rate from the 3rd day in ICR mice with lethal endotoxemia induced by LPS. These results suggest that CHHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as menstrual pain, menstrual disorder, leukorrhea, vaginitis, cervicitis, pelvic inflammatory disease and so on.

Tertomotide is a peptide vaccine developed for anti-cancer therapy. Since it has been found to ameliorate inflammatory symptoms in animal studies and clinical test, we investigated anti-inflammation activity of the tertomotide and the mechanism of action in monocyte in order to assess if tertomotide may serve as an anti-inflammatory agent by checking inflammatory cytokines and related signaling pathway following tertomotide treatment. We found that tertomotide reduced the level of pro-inflammatory cytokines such as TNF-α, IL-1β, IL-8 in LPS- or PMA-stimulated monocyte cell line and suppressed NF-κB signaling including the activation of ERK1/2 and P38 MAPK following TNF-α treatment. These results may correlate to the beneficial findings in animal studies, implicating that tertomotide may act as a potential anti-inflammatory agent. This study is an exemplary case for convergence that a computationally designed peptide for immunological purpose exerting unexpected biological activity may elicit novel anti-inflammatory drug.

Objective : The purpose of this study was to investigate the anti-inflammatory effects of Hwagae-san extract(HGSE) on the peritoneal macrophage. Methods : To evaluate anti-inflammatory effects of HGSE, We measured cytokines(interleukin-6; IL-6, interleukin-12; IL-12, tumor necrosis factor-${\alpha}$; TNF-${\alpha}$) and nitric oxide(NO) production in lipopolysaccharide(LPS)-induced macrophages. Furthermore, We examined molecular mechanism using western blot and also LPS-induced endotoxin shock. Results : 1. HGSE did not have any cytotoxic effect in the peritoneal macrophages. 2. HGSE reduced LPS-induced IL-6, TNF-${\alpha}$, IL-12 and NO production in peritoneal macrophages. 3. HGSE inhibited the activation of extracelluar signal-regulated kinase(ERK), C-Jun NH2-terminal kinase(JNK) but not of p38, degradation of IkB-${\alpha}$ in the LPS-stimulated peritoneal macrophages. 4. HGSE inhibited the production of TNF-$\alpha$, IL-6 and IL-12 in serum after LPS injection. Conclusion : These results suggest that HGSE may inhibit the production of TNF-${\alpha}$, IL-6, and IL-12 through inhibition of ERK and JNK activation, and that HGSE may be beneficial for inflammatory diseases.

This work aimed to elucidate the anti-inflammatory effects of ethyl acetate fraction from Cnidium officinale Makino with a cellular system of LPS-stimulated RAW 264.7 and THP-1 cells. Some key pro-inflammatory cytokines and mediators including NO, iNOS, $PGE_2$, COX-2, TNF-${\alpha}$, NF-${\kappa}B$ p50 and NF-${\kappa}B$ p65 were studied by sandwich ELISA and western blot analysis. Ethyl acetate fraction could significantly inhibit the production of NO, $PGE_2$, TNF-${\alpha}$, iNOS and COX-2 in LPS-stimulated cell than that of single LPS-stimulated. And ethyl acetate fraction suppresses the activation of NF-${\kappa}B$ p50 and NF-${\kappa}B$ p65. All the results showed that ethyl acetate fraction had a good anti-inflammatory effect on LPS-stimulated RAW264.7 and THP-1 cells. Taken together, the anti-inflammatory actions of ethyl acetate fraction from Cnidium officinale Makino might be due to the down-regulation of NO, $PGE_2$, TNF-${\alpha}$, iNOS and COX-2 via the suppression of NF-${\kappa}B$ activation.

Objective: In this study, we investigated the protective effect of rhododendron mucronulatum extract (RME) on allergic reactions and inflammation. Methods: The effect of RME was determined using ELISA and RT-PCR in RBL-2H3 mast cells and RAW 264.7 macrophage cells. We determined cell viability, β-hexosaminidase release, and the synthesis of IL-4 and TNF-α in RBL-2H3 cells. In addition, we determined NO from RAW 264.7 and the gene expression of IL-1β, iNOS, IL-6, TNF-α, and IL-10. Results: RME inhibited β-hexosaminidase release and synthesis of IL-4 and TNF-α in RBL-2H3 by the anti-DNP IgE plus DNP-HSA stimulation. In addition, RME inhibited the production of NO and the gene expression of IL-1β, iNOS, IL-6, and TNF-α in LPS-stimulated RAW 264.7 cells. Conclusion: From these results, we concluded that RME possesses anti-allergic activity and anti-inflammatory activity due to the inhibition of mast cells and macrophage function.

Objectives : On-Bi-Tang(OB) has been prescribed Chinese traditional medicine for the treatment of inflammatory disease such as chronic renal failure. In this study, we investigated the anti-inflammatory effect of OB extract in the BV2 murine microglial cells. Methods : After the water extract of OB was treated in BV2 cells, murine microglial line, the cell viability was measured by MTT assay. The production of nitric oxide (NO) and $TNF-{\alpha}$ was determined based on Griess reagent and enzyme linked immunosorbant assay (ELISA). mRNA expression of inducible nitric oxide synthase (iNOS) and $TNF-{\alpha}$ was analyzed by RT-PCR. Results : OB extract significantly inhibited the LPS-induced production of NO and TNF-a in BV2 cells. OB extract also suppressed the mRNA expression of iNOS and $TNF-{\alpha}$ in BV2 cells activated with LPS. Conclusion : These data suggests that OB extract may have the anti-inflammatory effect through the modulation of NO production and inflammatory cytokine such as $TNF-{\alpha}$.

The focus of this study was to clarify the relation between the nitric oxide (NO) production and cytokine expression including tumor necrosis factor-${\alpha}$ (TNF) and interleukin-6 (IL-6), and also investigated the effect of G-NANA (N-acylneuraminic acid isolates from glycomacropeptide) or S-NANA (Synthetic N-acylneuraminic acid) on LPS stimuli from RAW264.7 cell. The NANA is the predominant sialic acid found in mammalian cells and G-NANA is isolation of GMP (GMP is a valuable bioactive peptide with a varying degree of glycosylation including sialic acid). The lipopolysaccharide (LPS) of Gram-negative bacteria induces the expression of cytokines and potent inducers of inflammatory cytokines such as TNF-${\alpha}$ and IL-6. In this experiment, upon stimulation with increasing concentrations of chitosan, the LPS-stimulated TNF-${\alpha}$ and IL-6 secretion was significantly recovered with in the incubation media of RAW264.7 cells. Consistently, RT-PCR with mRNA and immunoblot analysis with anti-cytokine antiserum including TNF-${\alpha}$ and IL-6 showed that the amount of TNF-${\alpha}$ and IL-6 secretion in the incubation media recovered with the concentration of chitosan. The LPS-stimulated NO secretion was significantly recovered with in the 6 and 12 h incubation media of RAW264.7 cells, too. The recovery effect of G-NANA on IL-6 and NO secretion may be induced via the stimulus of TNF-${\alpha}$ in RAW264.7 cell. These results once again suggest that G-NANA may have the anti-inflammatory effect via the stimulus of TNF-${\alpha}$ in the LPS-stimulated inflammation in RAW264.7 cells.

Background: Galangin, commonly employed in traditional Chinese medicine for its diverse medicinal properties, exhibits potential in treating inflammatory pain. Nevertheless, its mechanism of action remains unclear. Methods: Mice were randomly divided into 4 groups for 7 days: a normal control group, a galangin-treated (25 and 50 mg/kg), and a positive control celecoxib (20 mg/kg). Analgesic and anti-inflammatory effects were evaluated using a hot plate test, acetic acid-induced writhing test, acetic acid-induced vascular permeability test, formalin-induced paw licking test, and carrageenan-induced paw swelling test. The interplay between galangin, transient receptor potential vanilloid 1 (TRPV1), NF-κB, COX-2, and TNF-α proteins was evaluated via molecular docking. COX-2, PGE2, IL-1β, IL-6, and TNF-α levels in serum were measured using ELISA after capsaicin administration (200 nmol/L). TRPV1 expression in the dorsal root ganglion was analyzed by Western blot. The quantities of substance P (SP) and calcitonin gene-related peptide (CGRP) were assessed using qPCR. Results: Galangin reduced hot plate-induced licking latency, acetic acid-induced contortions, carrageenan-triggered foot inflammation, and capillary permeability in mice. It exhibited favorable affinity towards TRPV1, NF-κB, COX-2, and TNF-α, resulting in decreased levels of COX-2, PGE2, IL-1β, IL-6, and TNF-α in serum following capsaicin stimulation. Galangin effectively suppressed the upregulation of TRPV1 protein and associated receptor neuropeptides CGRP and SP mRNA, while concurrently inhibiting the expression of NF-κB, TNF-α, COX-2, and PGE2 mRNA. Conclusions: Galangin exerts its anti-inflammatory pain effects by inhibiting TRPV1 activation and regulating COX-2, NF-κB/TNF-α expression, providing evidence for the use of galangin in the management of inflammatory pain.

Objective : Propionibacterium acnes (P. acnes) is a major pathogenic bacteria for acne vulgaris. This study was performed to evaluate the effects of Lithospermum erythrorhizon extracts on the inflammatory cytokines gene expression by P. acnes in human keratinocytes, HaCaT cell line. Methods : Anti-bacterial activity and cytotoxicity of LE extracts was analyzed by agar plate culture and XTT assay. The cytokines gene expressions were assessed by real time RT-PCR for IL-8, MCP-1 and TNF-${\alpha}$. During the cell culture and treatments, amounts of secreted TNF-${\alpha}$ were measured by ELISA. Translocation of transcription factor NF-${\kappa}B$ from cytoplasm into nucleus was observed by immunocytochemistry and confocal microscopy. Results : There were no anti-bacterial effects and cytotoxicity as high as $1,000{\mu}g/ml$ of LE extracts in XTT assay. Transcription levels of inflammatory cytokines, IL-8, MCP-1 and TNF-${\alpha}$ were increased by P. acnes in HaCaT. LE extracts decreased the upregulated gene transcription levels. However, amounts of secreted TNF-${\alpha}$ were similar in HaCaT cells with P. acnes and LE extracts. Translocation of NF-${\kappa}B$ into nucleus by P. acnes was significantly inhibited by LE extracts. Conclusions : From the results of this study, LE extracts have anti-inflammatory effects on HaCaT cells by P. acnes that decreased the mRNA expressions of IL-8, MCP-1 and TNF-${\alpha}$. This anti-inflammatory effects of LE extracts could provide the potential of therapeutic substance for acne vulgaris.
