Objective : KagamJwagwiEum(KJE) has been used for the purpose of prevention and treatment of bronchial asthma and allergic asthma in Korea. To investigate the biological effect of KJE, the author examined cytotoxicity and inflammatory cytokines secretion with human leukemic mast cell line, HMC-1. Methods: HMC-1 was stimulated with phorbol 12-myristate 13-acetate(PMA) and calcium ionophore A23187. KJE by itself had no effect on viability of HMC-l. The effects of KJE on the secretion of tumor necrosis $factor-alpha(TNF-{\alpha})$, interleukin(IL)-6 and IL-8 from HMC-1 were evaluated with enzyme-linked immunosorbent assay. Results : KJE inhibited PMA plus A23187-induced $TNF-{\alpha}$ and IL-6 secretion. But KJE had no effect IL-8 secretion: KJE had immunoregulatory effects on cytokines, increased secretion of NO and $TNF-{\alpha}$ but did not effect IL-12 secretion when the cells were primed and trigged with $IFN-{\gamma}$ in the peritoneal macrophages of C57BL/6 mice. Conclusions : Taken together, these results suggest that KJE inhibit the production of inflammatory cytokines in HMC-1 cells and activate macrophages.

Five known kaurane type diterpenoids, 16$\alpha$H, 17-isovaleryloxy-ent-kauran-19-oic acid (1), 16$\alpha$-hydroxy-17-isovaleryloxy-ent-kauran-19-oic acid (2), paniculoside-IV (3), 16$\alpha$-hydroxy-ent-kauran-19-oic acid (4), and ent-kaur-16-en-19-oic acid (5) were isolated from the root of Acanthopanax koreanum by repeated column chromatography and reversed phase preparative HPLC. The structures of these compounds were established from physicochemical and spectral data. Among the isolated compounds 16$\alpha$H, 17-isovaleryloxy-ent-kauran-19-oic acid (1) showed potent inhibitory activity ($IC_50$ value, 16.2 $\mu$ M) on TNF-$\alpha$ secretion from HMC-1, a trypsin-stimulated human leukemic mast cell line.

The Angelicae dahuricae radix (ADR) has been used a traditional medicine to treat acne, erythema, headache, toothache, sinusitis, colds, and flu in Korea, Japan and China. Here, we report the effect of ADR on compound 48/80-induced ear-swelling and the phorbol myristate acetate (PMA) plus calcium ionophore A23187-induced inflammatory cytokine secretion in the human mast cell line, HMC-1. ADR dose-dependently inhibited the ear-swelling response induced by intradermal injection of compound 48/80, In vitro model, PMA plus A23187 significantly increased interleukin $(IL)-1{\beta}$, IL-8, granulocyte macrophage colony stimulating factor (GM-CSF), and tumor necrosis factor $(TNF)-{\alpha}$ secretion compared with media control. We also show that the increased cytokines $IL-1{\beta}$, IL-8, GM-CSF, and $TNF-{\alpha}$ level was significantly inhibited by treatment of ADR. In addition, ADR partially blocked PMA plus A23187-induced extracelluar signal-regulated kinases phosphorylation. These results suggest that ADR might explain its beneficial effect in the treatment of mast cell-mediated inflammatory diseases.

The prevalence of allergic disease has been increasing over the past few decades in the majority of Western industrialized nations. There are some socioeconomic disparities regarding allergic disease status and management. Pyeongwee-San (KMP6) is Korean medicine for the treatment of gastrointestinal tract disease. It is known that KMP6 has an improving effect on the spleen and stomach functions in traditional Korean medical theory. Here, we hypothesized that KMP6 could be used to regulate the inflammatory reaction. We show the molecular mechanisms of Pyeongwee-San (KMP6) on inflammatory reactions. A molecular docking simulation showed that hesperidin, component of KMP6, regulate the enzymatic activity by interaction in the active site of caspase-1. KMP6 control the activity of caspase-1 in activated human mast cell line (HMC-1 cells). KMP6 reduced the expression of receptor interacting protein (RIP)-2 in HMC-1 cells. Thymic stromal lymphopoietin protein production and mRNA expression were inhibited by KMP6. In the activated HMC-1 cells, KMP6 suppressed the activation of mitogen-ativated protein kinase and nuclear factor-kappaB. In addition, KMP6 significantly inhibited the expression of inflammatory cytokines. Our findings indicate that KMP6 may attenuate allergic reactions via the regulation of caspase-1/RIP-2 signaling pathway. These studies will help advance the social welfare system.

The mast cell is one of the major effector cells in inflammatory reactions and can be found in most tissues throughout the body. Activated mast cells can produce histamine, as well as a wide variety of other inflammatory mediators such as eicosanoids, proteoglycans, proteases, and several pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-${\alpha}$, and interleukins (IL-6), IL-8, IL-4, IL-13. In the present study, we isolated two bacterial strains (J80 and G147) from fermented soybean and Jeotgal, and investigated the inhibitory effects of their extracts which were prepared by several pretreatment methods (sonication for 20 min, heating at $100^{\circ}C$ for 30 min, autoclaving at $121^{\circ}C$ for 15 min) on the mast cell-mediated inflammatory response. The pretreated bacterial extracts had no cytotoxicity against Human Mast Cell (HMC-1). Among various pretreatments, the extracts treated at $100^{\circ}C$ showed highest inhibition of histamine release (J80, 28.46%; G147, 41.14%). The J80 and G147 extracts treated at $100^{\circ}C$ resulted in the inhibition of IL-6 secretion by 38.46% and 56.45%, respectively. The J80 extract treated at $100^{\circ}C$ resulted in the inhibition of TNF-${\alpha}$ secretion by 66.67%, but G147 extract showed the highest inhibition effect by 41.1% when treated with sonication. These results suggest that bacterial extracts treated at $100^{\circ}C$ have a higher level of anti-inflammatory effects than other treatments such as sonication or autoclaving.

Objectives : Sinhyowoldo-san (SHWDS) is said to be a traditional medicine used for shigellosis, abdominal pain, diarrhea. But mechanism of SHWDS mediated-modulation of immune function is not sufficiently understood. To ascertain the molecular mechanisms of SHWDS 70% EtOH extract on pharmacological and biochemical actions in inflammation, we researched the effect of pro-inflammatory mediators in phorbol-12-myristate-13-acetate (PMA)+ A23187-activated human mast cell line (HMC-1). Methods : In the present research, cell viability was measured by MTS assay. pro-inflammatory cytokine production was measured by performing enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and western blot analysis to analyze the activation of mitogen-activated protein kinases (MAPKs), nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$). The investigation focused on whether SHWDS inhibited the expressions of interleukin-6 (IL-6), interleukin-8 (IL-8), MAPKs and $NF-{\kappa}B$ in PMA+A23187-activated HMC-1 cells. Results : SHWDS has no cytotoxicity at measured concentration (50, 100, and $250{\mu}g/ml$). SHWDS ($250{\mu}g/ml$) inhibits pro-inflammatory cytokine expression in PMA+ A23187-activated HMC-1 cells. Moreover, SHWDS inhibited cyclooxygenase (COX)-2 expression. In activated HMC-1 cells, SHWDS suppressed phosphorylation of extracellular signal-regulated kinase (ERK 1/2) and c-jun N-terminal Kinase (JNK 1/2). Then, SHWDS suppressed activation of nuclear factor $NF-{\kappa}B$ in nuclear, degradation of IkB ${\alpha}$ in cytoplasm. Conclusions : We propose that SHWDS has an anti-inflammatory therapeutic potential, which may result from inhibition of ERK 1/2, JNK 1/2 phosphorylation and $NF-{\kappa}B$ activation, thereby decreasing the expression of pro-inflammatory genes.

In our previous study, a new herbal preparation (HemoHIM) was developed as a functional food for the radioprotection and immunomodulatory agents. In order elucidate the mechanism involved, we examined the effect of HemoHIM on the compound 48/80-induced histamine release, and on the phorbol 12-myristate 13-acetate (PMA)/calcium ionophore (A23187)-induced inflammatory cytokine secretion in HMC-1. The cell culture supernatants were harvested, and the cytokines (IL-4, IL-6, IL-8, TNF-$\alpha$, GM-CSF) in the supernatants were measured by enzyme-linked immunosorbent assay. The total RNA of the cells was extracted, and the cytokines or c-kit/tryptase/Fc$\varepsilon$RI's messenger RNA expressions were examined using reverse transcriptase polymerase chain reaction. Under low concentrations, HemoHIM inhibited histamine release in HMC-1 stimulated compound 48/80. Furthermore HemoHIM inhibited PMA/A23187-induced inflammatory cytokines' secreation or mRNA expression in a dose-dependent manner. But IL-8 secretion was not inhibited by low concentrayion of HemoHIM, respectively. The mRNA expression of c-kit and Fc$\varepsilon$RI were also inhibited in a dose-dependent manner. Tryptase mRNA expression was only inhibited by low concentration of HemoHIM. These results indicated that HemoHIM might be an useful agent for protection against allergy as well as immune modulation, especially since it is a relatively nontoxic natural product.

We studied the effect of Bamboo salt-pro on the growth and acid production of S. mutans. The growth of S.mutans was reduced by the presence of the Bamboo salt-pro (1 mg/ml) and NaCl (1 mg/ml) significantly, and the positive control group (1 % of NaF) also exhibited antibacterial activity significantly. Bamboo salt-pro (1 mg/ml) reduced the rate of acid production by S. mutans. Bamboo salt alone did not demonstrate such a reduction in acid production at the concentration of 1 mg/ml. The inhibitory action of Bamboo salt-pro on acid production was found at a concentration of 1 mg/ml, but bamboo salt alone was not at a concentration of 1 mg/ml. In addition, we investigated the anti-inflammatory effect of Bamboo salt-pro on human mast cell line HMC-1. Bamboo salt-pro (0.1 and 0.01 mg/ml) inhibited significantly the secretion of inflammatory cytokine, tumor necrosis factor-a with $59.47{\pm}0.15%$, $51.98{\pm}0.16%$ respectively. Our results suggest that Bamboo salt-pro importantly contributes to the prevention or treatment of periodontitis and other oral diseases and inflammatory diseases.

Trichomonas vaginalis causes the most prevalent sexually transmitted infection worldwide. Trichomonads have been detected in prostatic tissues from prostatitis, benign prostatic hyperplasia (BPH), and prostate cancer. Chronic prostatic inflammation is known as a risk factor for prostate enlargement, benign prostatic hyperplasia symptoms, and acute urinary retention. Our aim was to investigate whether T. vaginalis could induce inflammatory responses in cells of a benign prostatic hyperplasia epithelial cell line (BPH-1). When BPH-1 cells were infected with T. vaginalis, the protein and mRNA of inflammatory cytokines, such as CXCL8, CCL2, IL-$1{\beta}$, and IL-6, were increased. The activities of TLR4, ROS, MAPK, JAK2/STAT3, and NF-${\kappa}B$ were also increased, whereas inhibitors of ROS, MAPK, PI3K, NF-${\kappa}B$, and anti-TLR4 antibody decreased the production of the 4 cytokines although the extent of inhibition differed. However, a JAK2 inhibitor inhibited only IL-6 production. Culture supernatants of the BPH-1 cells that had been incubated with live T. vaginalis (trichomonad-conditioned medium, TCM) contained the 4 cytokines and induced the migration of human monocytes (THP-1 cells) and mast cells (HMC-1 cells). TCM conditioned by BPH-1 cells pretreated with NF-${\kappa}B$ inhibitor showed decreased levels of cytokines and induced less migration. Therefore, it is suggested that these cytokines are involved in migration of inflammatory cells. These results suggest that T. vaginalis infection of BPH patients may cause inflammation, which may induce lower urinary tract symptoms (LUTS).
