Polygoni cuspidati Rhizoma (PCRH) has been used in treatment of menoxenia, skin burn, gallstone, hepatitis, hyperlipidaemia, favus athlete's foot, supperative dermatitis and inflammation. However, its effect in experimental models remains unknown. In this present study, the effect of PCRH for stability on mast cell was analyzed. Two g/kg PCRH inhibited the compound 48/80-induced anaphylaxis by 75%. In addition, PCRH inhibited the tumor necrosis factor-$\alpha$ and interleukin-8 secretion as compared with the phorbol 12-myristate 13-acetate plus calcium ionophore A23187 stimulated human mast cell line, HMC-1 cells. These results suggested PCRH may inhibit mast cell-mediated anaphylactic reaction.

The effect of aqueous extract of Stachys riederi var. japonica Miq. (Labiatae) (SRAE) on the immediate-type allergic reactions was investigated. SRAE was found to exhibit a inhibitory activity on the compound 48/80-induced systemic anaphylaxis in mice. SRAE inhibited the plasma histamine release induced by compound 48/80 in mice. In addition, SRAE also inhibited the passive cutaneous anaphylaxis reaction induced by IgE/anti-IgE in mice. The effect of SRAE on the histamine release from rat peritoneal mast cells (RPMC) was studied. SRAE inhibited the histamine release induced by compound 48/80 in RPMC. To clarify the mechanism of these inhibiting reactions, we investigated the effects of SRAE on cyclic AMP (cAMP). The level of cAMP in human leukemia cell line, HMC-1, when SRAE (1 mg/ml) was added, significantly increased compared with that of basal cells. These results indicate that SRAE may be beneficial in the treatment of immediate-type allergic reaction.

Lonicera japonica Thunb.(Caprifoliaceae) has long been known as an anti-inflammatory. In the present study, the effect of water fraction of Lonicera japonica (LJ) on trypsin-induced mast cell activation was examined. HMC-1 cells were stimulated with trypsin (100 nM) in the presence or absence of LJ (10, 100, and 1000 $\mu$ g/mL). TNF-$\alpha$ and tryptase production were measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-PCR. Extracellular signal-regulated kinase (ERK) phosphorylation was assessed by Western blot. Trypsin activity was measured by using Bz-DL-Arg-p-nitroanilide (BAPNA) as substrate. LJ (10, 100, and 1000 $\mu$g/mL) inhibited TNF-$\alpha$ secretion in a dose-dependent manner. LJ (10, 100, and 1000 $\mu$g/mL) also inhibited TNF-$\alpha$ and tryptase mRNA expression in trypsin-stimulated HMC-1. Furthermore, LJ inhibited trypsin-induced ERK phosphorylation. However, LJ did not affect the trypsin activity even 1000 $\mu$g/mL. These results indicate that LJ may inhibit trypsin-induced mast cell activation through the inhibition of ERK phosphorylation than the inhibition of trypsin activity.

Objective : To demonstrate of regulatory effect of atopic allergic regulation by Chungsangbangpoong-Tang(CBT), This experiment was studied. Methods : The author investigated a possible effect of CBT on cytokines production using human T cell line (MOLT-4) or human mast cell line (HMC-1). In addition, the author investigated whether CBT has inhitory effects on compound 48/80- induced histamine release from rat peritoneal mast cells (RPMC) and compound 48/80-induced ear swelling in ICR mice. Results : CBT (0.01 mg/ml)-containing medium in stimulated culture supernatants significantly increased IL-2 secretion compared with untreated MOLT-4, whereas CBT (0.01-1.0 mg/ml)-containing medium in stimulated culture supernatants significantly decreased IL-4 secretion compared with untreated MOLT-4. Significant reduced levels of IL -6 and $TNF-{\alpha}$ were observed in the HMC-l with CBT (P<0.05). CBT did not inhibit the histamine release from the RPMC but inhibit ear swelling response. Conclusion : These results suggest that CBT contributes to the treatment of atopic allergic reactions, such as atopic dermatitis and that its action may be due to regulation of cytokine production.

Objectives : This study was carried out to investigate the effects of Polygonum cuspidatum extract on several skin functions including inflammation and wrinkle formation. Methods : To investigate in vitro anti-oxidant activity assay, ethanol extracts of medicinal plants tested by DPPH method. In the next experiment, to investigate anti-inflammatory test, the RAW 264.7 macrophage cells was cultured using DMEM including the 10% FBS. To study anti-allergic effect, we blended cultured Human Mast Cells(HMC-1), and then observe $TNF-{\alpha}$, IL-8 by ELISA Results : Polygonum Cuspidatum extract has the effects of anti-inflammation and anti-allergy, which may be due to its inhibitory potential on the macrophage activation. Furthermore, Polygonum Cuspidatum extract has the anti-wrinkle effects through the inhibitory potential on the collagnease, elastase and gelatinase activities. Conclusions : The above results suggest that Polygonum Cuspidatum extract could be applicable for improvement of several skin functions.

We studied the effect of Rubus croceacanthus Leveille (RCL) on mast cell-mediated anaphylactic reactions. RCL inhibited compound 48/80-induced systemic anaphylactic shock. When RCL was given at concentrations ranging from 0.01 to 1 mg/$m\ell$, the histamine release from rat peritoneal mast cells induced by compound 48/80 was reduced in a dose-dependent manner. RCL also inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl IgE. In addition, RCL inhibited phorbol 12-myristate 13-acetate and A23187-induced tumor necrosis factor-${\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that RCL may possess a strong anti-anaphylactic activity.

Lindera obtusiloba has been used for centuries as a traditional medicine in Korea and recently known to have an anti-fibrotic effect. In this report, we investigated the effect of hot water extract from L. obtusiloba (WELB) on the mast cell-mediated allergic inflammation and studied its possible mechanisms of action. WELB inhibited phorbol-12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-induced histamine release in HMC-1 human mast cells. WELB reduced PMACI-induced gene expression and secretion of proinflammatory cytokines such as tumor necrosis factor-$\alpha$, interleukin (IL)-$1{\beta}$, IL-6, and IL-8. The inhibitory effect of WELB on the expression of proinflammatory cytokines was c-jun N-terminal kinase and nuclear factor-${\kappa}B$ dependent. These results indicate that WELB may be beneficial in the treatment of mast cell-mediated allergic inflammation.

This study was conducted to investigate the anticancer (in vitro) and antiallergy effects of rice bran extracts. In an anticancer test using Hep3B cells and HeLa cells, water and 60% ethanol extracts of rice bran inhibited the growth of Hep3B and HeLa cell lines and morphological changes were also observed. In Hep3B cell lines, water extract of rice bran showed a higer antiproliferating effect than 60% ethanol extract. The growth-inhibitory effect against HeLa cells were 30.9% for $1,000{\mu}g/mL$, 88.8% for $3,000{\mu}g/mL$ rice bran water extract. The expressions of $Fc{\varepsilon}RI$ mRNA and c-kit in HMC-1 (human mast cell) were decreased by 60% ethanol treatment but tryptase mRNA was not changed. The extracts of rice bran inhibited histamine release from RPMC (rat peritoneal mast cell) activated by compound 48/80. Rice bran water extract showed inhibitory effect of 87% at $0.01{\mu}g/mL$ concentration and 60% ethanol extract inhibited the release of histamine by 86% at $100{\mu}g/mL$ concentration.

We studied the effect of methanol extract of Carpopeltis affinis (CA) on atopic allergic reaction. CA dose-dependently inhibited interleukin (IL)-8 and tumor necrosis factor (TNF)-$\alpha$ secretion from the PMA- plus A23187- stimulated HMC-1. CA also dose-dependently inhibited the histamine and $\beta$-hexosaminidase release from mast cells. CA had no cytotoxic effect. (omitted)
