Mast cells accumulation can be causally related with several allergic inflammations. Previous work has demonstrated that glucocorticoids decreased tissue mast cell number and stem cell factor (SCF)-induced migration of mast cells required p38 mitogen-activated protein kinase (MAPK) activation. In the present study, we investigated the effects of dexamethasone on SCF-induced migration of rat peritoneal mast cells (RPMCs). SCF significantly induced migration of RPMCs at 4 h. Dexamethasone dose-dependently inhibited SCF-induced migration of RPMCs (about 90.1% at 100 nM, P<0.05). MAPK p38 inhibitor, SB203580 (20 ${\mu}$M) also inhibited the SCF-induced migration. The ability of SCF to enhance morphological alteration and F -actin formation was also abolished by treatment of dexamethasone. Dexamethasone inhibited SCF-induced p38 MAPK activation to near basal level and induced the MKP-1 expression. In addition, SCF-induced inflammatory cytokine production was significantly inhibited by treatment of dexamethasone or SB203580 (p<0.01). Our results show that dexamethasone potently regulates SCF -induced migration, p38 MAPK activation and inflammatory cytokine production through expression of MKP-l protein in RPMCs. Such modulation may have functional consequences during dexamethasone treatment, especially mast cell-mediated allergic inflammation disorders.

We studied the effects of the powders of Spirulina platensis (SPP) on anaphylactic reactions. SPP inhibited systemic anaphylaxis induced by compound 48/80 in rats. SPP also inhibited local anaphylaxis activated by anti-dinitrophenyl(DNP) IgE. Moreover, SPP dose-dependently inhibited histamine release in rat peritoneal mast cells activated by compound 48/80 or anti DNP-IgE. These results suggest that SPP may contain compounds with actions that inhibit mast cell degranulation in the rat.

The fruits of Piper cubeba L. are used traditionally to treat respiratory disorders in Indonesia. In order to determine the compounds responsible for this activity, the fruits were extracted with nhexane followed by ethanol to give n-hexane and ethanol extracts. Based on tracheospasmolytic assay on these two extracts, the n-hexane extract was more active to inhibit trachea contraction than that of ethanol extract. Upon bioassay guided isolation of the n-hexane extract, a tracheospasmolytic active compound was isolated and identified as dihydrocubebin [(3,4),(3',4')-bis-methylenedioxy-9,9'dihydroxylignan] $(\underline{1})$. Compound $\underline{1}$ was tested further for its ability to inhibit histamine released from mast cells, using rat basophilic leukemia (RBL-2H3) cell line and rat peritoneal mast cells RPMCs) as models; and $DNP_{24}$-BSA, thapsigargin, ionomycin, compound 48/80 and PMA were used as inducers for histamine released from mast cell. The test result showed that $\underline{1}$ inhibited histamine release from RBL-2H3 cells induced by $DNP_{24}$-BSA, thapsigargin and ionomycin. In addition, $\underline{1}$ suppressed histamine release from RPMC induced by either thapsigargin or ionomycin. However, $\underline{1}$ did not inhibit histamine release from RPMC induced by either compound 48/80 or combination PMA-sub optimum dose of ionomycin. Therefore, it was concluded that the inhibitory effects of $\underline{1}$ on the histamine released from mast cells may involve mechanisms related to intracellular $Ca^{2+}$ signaling events or downstream processes of intracellular $Ca^{2+}$ signaling in mast cells.

Dendroaspis natriuretic peptide (DNP)는 최근에 green Mamba snake Dendroaspis angusticeps의 독(venom)에서 발견된 17개의 아미노산 disulfide링 구조를 포함하는 38개 아미노산 펩티드로 natriuretic peptide family와 그 구조가 비슷하다. Natriuretic peptide family는 사람과 흰쥐 비만세포로부터 히스타민을 유리시킨다고 알려져 있다. 그러나 DNP가 비만 세포로부터 히스타민을 유리 시키는 여부는 밝혀져 있지 않다. 본 연구는 DNP가 흰쥐 복강 비만세포로부터 히스타민을 유리시키는 여부와 함께 히스타민 유리기전을 구명하고자 실시되었다. 다양한 농도의 DNP를 흰쥐 복강 비만세포에 처리한 다음, 비만세포의 탈과립을 도립 광학현미경으로 관찰하였다. 히스타민 유리량은 방사효소법으로 측정하였고 세포내 칼슘 유입량과 cyclic GMP의 수준은 방사면역법으로 측정하였다. DNP는 흰쥐 복강 비만세포를 탈과립시켰고 농도가 증가함에 따라 비만세포로부터 히스타민 유리량이 증가되었다. 또한 DNP는 농도 증가에 비례하여 비만세포 안으로 세포밖의 칼슘을 유입시켰으며 세포안의 cyclic GMP의 수준을 증가시켰다. 이상의 결과로 미루어, DNP는 비만세포 안의 cyclic GMP와 칼슘의 농도를 증가시켜 비만세포로부터 히스타민을 유리시키는 것으로 생각된다.

Mahwang-Shin-Gung-San has been found inhibiting the mast cell-mediated anaphylactic reaction. This report describes an inhibitory effect of Mahwang-Shin-Gung-San (MSGS) on the immediate-type cutaneous allergic reactions. MSGS has concentration -dependently inhibited the ear swelling response induced by compound 48/80 in mouse by intradermal injection. The mast cells in mouse ear tissue undergone ear-swelling response by compound 48/80 were stained by alcian blue/nuclear fast red. MSGS significantly inhibited the compound 48/80-induced degranulation from mast cells in ear tissue. MSGS concentration-dependently inhibited the histamine release from the rat peritoneal mast cells (RPMC) by compound 48/80. We also studied the effect of MSGS on mast cell-dependent passive cutaneous anaphylaxis (PCA) activated by dinitrophenyl IgE antibody. MSGS showed potent inhibition of PCA by oral administration. These results indicate that MSGS inhibits immediate-type allergic reactions by inhibition of mast cell degranulation in vivo and in vitro.

Objective : Moutan Cortex (the root bark of Paeonia suffruticosa Andr.) is widely used in oriental medicine as a remedy for inflammation. However, as yet there is no clear explanation of how MC(Moutan Cortex) affects the production of inflammatory cytokine. This study was to determine the effects of Essence extracted MC on the mast cell-mediated inflammatory responses. Method : We observed the effect of MC on compound 48/80-induced histamine release of rat peritoneal mast cells and the effect of administering MC on PCA in rat. We measured the amount of inflammatory cytokine production induced by the phorbol myristate acetate (PMA) plus calcium ionophore(A23187) in the human mast cell line (HMC-1) incubated with various concentrations of MC. The TNF-$\alpha$ protein levels were analysised by Western blot. The TNF-$\alpha$, IL-6 and IL-8 secreted protein levels were measured by the ELISA assay. The TNF-$\alpha$, IL-6 and IL-8 mRNA levels were measured by the RT-PCR analysis. NF-$\kappa$B, phospho-I$\kappa$B and MAPKs were exmined by Western blot analysis. The NF-$\kappa$B promoter activity was examined by luciferase assay. Result : 1. Enzyme immunoassay indicated that MC suppressed histamine secretion of rat peritoneal mast cells. 2. In PCA dependent on IgE, MC had anti-allergic effect of the internal surface of rat skin. 3. Western blot indicated that MC decreased TNF-$\alpha$ protein levels. 4. ELISA indicated that MC decreased TNF-$\alpha$, IL-6 but MC had no significant effect on IL-8 in HMC-1 cells. 5. RT-PCR indicated that MC decreased TNF-$\alpha$, IL-8 but MC had no significant effect on IL-6 in HMC-l cells. 6. Western blot indicated that MC suppressed the induction of MAPKs, NF-$\kappa$B & phospho-I$\kappa$B activity in HMC-1 cells. 7. Luciferase assay indicated that MC suppressed the PMA plus A23187-induced NF-$\kappa$B promoting activityin HMC-1 cells. Conclusion : In this study, we have found that MC is an inhibitor of NF-$\kappa$B, MAPKs & cytokines on the mast cell-mediated inflammatory responses.

The effects of aqueous extract of Artemisia iwayomogi (Compositae) (AIAE) on the mast cell-dependent allergic and inflammatory reactions were investigated. AIAE (0.05 to 1 g/kg) dose-dependently inhibited systemic allergic reaction induced by compound 48/80 in mice. AIAE (0.1 and 1 g/kg) also significantly inhibited local allergic reaction activated by anti-DNP IgE. AIAE (0.001 to 1 mg/ml) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. Moreover, AIAE inhibited the secretion of interleukin (IL)-6 in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-stimulated human mast cell line (HMC-1) cells. These results provide evidence that AIAE may be beneficial in the treatment of allergic diseases.

Objective : Mast cells are a potent source of mediators that regulate inflammatory response in allergies and asthma. The author studied the effect of Bojungikgitanggamibang(BITB) on mast cell-mediated anaphylactic reaction. Method : When BITB was given as pre-treatment at concentrations ranging from 0.01 to 1 mg/ml, the histamine release from rat peritoneal mast cells induced by compound 48/80 was reduced in a dose-dependent manner. Result : BITB dose-dependently inhibited compound 48/80-induced systemic anaphylactic shock. BITB also inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl IgE. In addition, BITB inhibited phorbol 12-myristate 13-acetate and A23187-induced interleukin-6 secretion from human mast cell line HMC-1 cells. Conclusion : These results indicate that BITB may be actively anti-allergic.

Effects of Panax ginseng on allergic reactions were studied uslng various in vivo and in vitro experimental models such as 48-hr passive cutaneous anaphylaxis, mediators-induced skin reactions, histamine release from rat peritoneal mast cells, hexosaminidase release from RBL-2H3 cells, and lipoxygenase assay . In all of anti-allergic experiments we conducted, ginseng components (50% ethanol extract or ginseng total saponin or ginsenosides) extracted from Korean red ginseng, did not show significant anti-allergic actions. In 48-hr passive cutaneous anaphylaxis and mediators-induced skin reactions, 50% ethanol extract did not suppress hypersensitivity reactions. Total saponin, 50% ethanol extract, and 8 major ginsenosides did not show inhibitory effects on lipoxygeanse activity. Ginseng total saponin did not inhibit histamine release from rat peritoneal mast cells. All of the ginseng components mentioned above were also tested on RBL-2H3 cells, but none of them inhibited hexosaminidase release from this cell line. These results suggest that Panax ginseng does not have effects on allergic reactions at the level of 50% ethanol extract or total saponin used. All of 8 major saponin components tested ($Rb_1$, $Rb_2$, Rc, Rd, Re, Rf, $Rg_1$, $Rg_2$), did not inhibit lipoxygenase activity and degranulation events.
