In the present study, we investigated the effect of the water extract of Perilla frutescens var. acuta (Labiatae; WEPF) on the mast cell-mediated allergic reactions. WEPF was anally administered to mice for high and fast absorption. WEPF inhibited compound 48/80-induced systemic allergic reaction. WEPF attenuated immunoglobulin E (IgE)-mediated local allergic reaction. In addition, WEPF decreased the gene expression of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated HMC-1 cells. These results indicate that WEPF inhibits mast cell-mediated allergic reactions in vivo and in vitro.

Immediate-type hypersensitivity is involved in many allergic diseases such as asthma, allergic rhinitis and anaphylaxis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. Stimulation of mast cells releases inflammatory mediators, such as histamine and pro-inflammatory cytokines with immune regulatory properties. We investigated the effect of the aqueous extract of Schizonepeta tenuifolia (AEST) (Labiatae) on the immediate-type allergic reaction. AEST inhibited compound 48/80-induced systemic allergic reaction. AEST attenuated immunoglobulin E (IgE)-mediated skin allergic reaction and histamine release from human mast cell line (HMC-1) cells. In addition, AEST decreased the gene expression and secretion of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-stimulated HMC-1 cells. Our results indicate that AEST inhibits the mast cell-derived allergic reactions and involvement of histamine and pro-inflammatory cytokines in these effects.

The present study was designed in order to determine whether Lonicerae flos (LF) could mitigate rheumatoid arthritis through inhibition of cyclooxygenase (COX)-2 and matrix metalloproteinase (MMP)-9 by regulation of macrophage migration inhibitory factor (MIF). We found that MIF mRNA expression in synoviocytes stimulated with phorbol-12-myristate-13-acetate dose-dependantly decreased by LF extract treatment (0.4 - 1.0 mg/$m{\ell}$). The distribution of MIF, COX-2 and MMP-9 positive reacted cells in LPS induced arthritis of mice were decreased by LF (45 mg/kg/day) treatment for 28 days. These data likely indicate that LF may act as MIF inhibitor and may be possible to develop useful agent for rheumatoid arthritis.

The aim of the present study was to elucidate whether gallic acid could modulate the inflammatory allergic reaction and to study its mechanism of action Gallic acid inhibited compound 48/80- or immunoglobulin E (IgE)-induced histamine release from mast cells. The inhibitory effect of gallic acid on the histamine release was mediated by modulation of cAMP and intracellular calcium. Gallic acid decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated pro-inflammatory cytokine gene expression and production such as TNF- ${\alpha}$ and IL-6 in human mast cells, and the inhibitory effect of gallic acid was on dependent nuclear factor- ${\kappa}$B and p38 mitogen-activated protein kinase. Our findings provide evidence that gallic acid inhibits mast cell-derived inflammatory allergic reaction by blocking histamine release and pro-inflammatory cytokine expression.

In this study, we investigated whether eriodictyol exerts an effect on the production and gene expression of MUC5AC mucin in human pulmonary epithelial NCI-H292 cells. The cells were pretreated with eriodictyol for 30 min and then stimulated with phorbol 12-myristate 13-acetate (PMA) for 24 h. The effect of eriodictyol on PMA-induced nuclear factor kappa B (NF-κB) signaling pathway was also investigated. Eriodictyol suppressed the MUC5AC mucin production and gene expression induced by PMA via suppression of inhibitory kappa Bα degradation and NF-κB p65 nuclear translocation. These results suggest that eriodictyol inhibits mucin gene expression and production in human airway epithelial cells via regulation of the NF-κB signaling pathway.

In the course of our search for intercellular adhesion molecule-1 (ICAM-1)/leukocyte function-associated antigen-1 (LFA-1) mediated cell adhesion inhibitors from natural sources, new type of cell adhesion inhibitors were isolated from the MeOH extract of Saururus chinensis roots. On the basis of spectral evidence, the structures of the active compounds were identified as manassantin A and B. Manassantin A and B inhibited phorbol 12-myristate 13-acetate (PMA)-induced homotypic aggregation of the human promyelocytic leukemia HL-60 cells without cytotoxicity with MIC value of 1.0 and 5.5 nM, respectively.

In this study, we examined whether engeletin exerts an effect on the gene expression of MUC5AC mucin, in human pulmonary epithelial NCI-H292 cells. The cells were pretreated with engeletin for 30 min and stimulated with phorbol 12-myristate 13-acetate (PMA), for the following 24 h. The effect of engeletin on PMA-induced nuclear factor kappa B (NF-kB) signaling pathway was also investigated. Engeletin suppressed the mRNA expression and production of MUC5AC mucin, induced by PMA through the inhibition of degradation of inhibitory kappa Bα (IkBα) and NF-kB p65 nuclear translocation. These results suggest engeletin inhibits the gene expression of mucin through regulation of NF-kB signaling pathway, in human airway epithelial cells.

In this study, artesunate, an antimalarial agent, was investigated for its potential effect on the gene expression of airway MUC5AC mucin. The human pulmonary epithelial NCI-H292 cells were pretreated with artesunate for 30 min and then stimulated with phorbol 12-myristate 13-acetate (PMA), for the following 24 h. The effect of artesunate on PMA-induced nuclear factor kappa B (NF-kB) signaling pathway was also examined. Artesunate inhibited the glycoprotein production and mRNA expression of MUC5AC mucins, induced by PMA through the inhibition of degradation of inhibitory kappa Bα (IkBα) and NF-kB p65 nuclear translocation. These results suggest artesunate suppresses the gene expression of mucin through regulation of NF-kB signaling pathway, in human pulmonary epithelial cells.

붕어의 년 생식주기를 밝히기 위해 1993년 2월부터 1994년 10월까지 gonadosomatic index (GSI)를 조사하였다. GSI는 4월부터 7월까지는 높은 수준을 나타내며 개체간에 편차가 큰 것으로 보아 이 기간이 산란기임을 보여준다. 8월부터 9월까지는 년중에서 가장 낮은 수준이며 이때 난소내 여포는 퇴화가 진행 중이었다 10월부터 GSI 값은 증가하여 이듬해 3월에 최대치를 보였다. Human chorionic gonadotropin (HCG 10 lU), $17\alpha$, 20\beta-dihydroxyprogesterone\;(1-100{\mu}g/ml)$ 및 phorbol 12-myristate 13-acetate (TPA, protein kinase C activator, 0.1-10${\mu}M$)는 인공배양 시 난모세포의 성숙을 유도하였으나 $4\alpha-phorbol$ 12, 13-didicanoate ($4\alpha-PDD$, phorbol ester analogue, $(25{\mu}M$)는 성숙을 일으키지 않았다. 또한, HCG (10 IU), prostaglandin $F_{2\alpha}$ (0.1-10${\mu}g/ml$) 및 TPA (0.1-10${\mu}M$)는 난모세포의 배란을 유도하였으나 $4\alpha-PDD$$(25\;{\mu}M)$에 의해서는 배란이 일어나지 않았다. 여포세포의 $17\alpha-hydroxyprogesterone$은 HCG (1 IU, 10 IU) 및 forskolin (adenylate cyclase activator, 0.1-10 ${\mu}M$)에 의해 생성이 촉진되었으며 HCG (10 IU) 및 forskolin $(10 {\mu}M)$에 의한 time course 는 3시간 내에 생성량이 증가하여 시간경과에 따른 유의한 차이는 보이지 않았다. 이러한 결과를 종합하면 cyclic AMP와 protein kinase C 는 어류의 난모세포의 성숙과 배란과정에 매우 중요한 역할을 담당하는 것으로 생각된다.

염생식물인 비쑥은 식용이 가능한 약용식물로서 살충, 항염, 항콜레스테롤, 해열, 항균 활성 등이 알려져 있다. 본 연구에서는 phorbol-12-myristate-13-acetate (PMA)로 자극된 인간 섬유육종 HT-1080 세포에서 5가지 활성검색방법 즉 : gelatin zymography, MMPs ELISA, wound healing assay, reverse transcription-polymerase chain reaction (RT-PCR), Western blot을 이용하여 비쑥의 조추출물과 그 용매 분획물의 MMP-2와 MMP-9 효소 활성에 대한 저해 효과를 평가하였다. 비쑥 시료들을 메틸렌 클로라이드(MC)와 메탄올(MeOH)로 각각 2번 추출하여 합한 것을 조추출물로 사용하였으며 이 조추출물은 MMP-2와 MMP-9 효소활성에 대해 유의한 억제 효과를 나타내었다. 이 조추출물은 용매극성에 따라 다시 n-hexane, 85% aq.MeOH, n-butanol 및 물 분획층으로 분획되었으며 이렇게 얻어진 4개의 용매 분획물들중에 n-hexane과 85% aq.MeOH 분획이 gelatin zymography와 MMP ELISA assay에서 MMP-2와 MMP-9의 활성을 효과적으로 억제하였다. 또한 wound healing assay, RT-PCR 및 Western blot assay에서 H₂O 분획을 제외한 모든 용매 분획물들이 세포 이동, 그리고 MMP-2 및 MMP-9의 mRNA와 단백질 발현을 유의하게 억제하였다.
