Objectives : In this study, we attempted to evaluate the effects of Careswell on human mast cell-mediated allergy inflammation in vitro and pruritogen-induced scratching behavior in vivo. Method : The Careswell was extract by distilled water. The anti-itching effects of Careswell were investigated on the compound 48/80 ($50{\mu}g/kg$) or histamine ($100{\mu}g/kg$) induced scratching behavior male ICR mice for 30 min by an observer blind. Terfenadine (10 mg/kg) was used as a positive control drug. The cell toxicity of Careswell was determined by 3-(4,5-dimethylthiazole-2-yl)-2, 5-diphenyl-tetrazolium bromide (MTT) assay. The regulatory effect of Careswell on interleukin (IL)-6 and tumor necrosis factor (TNF)-${\alpha}$ levels was determined by enzyme-linked immunosorbent assay (ELISA) in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI) stimulated human mast cells (HMC-1). Also, we evaluated the effect of Careswell on PMACI induced the activation of Nuclear factor-kappa B (NF-${\kappa}B$) into nucleus by Western blot analysis. Result : The results revealed that the oral administration of Careswell (200 mg/kg, p.o.) attenuated the compound 48/80 or histamine-induced scratching behavior in mice. We showed that Careswell significantly reduced the PMACI-induced the production of IL-6 (0.5-1 mg/ml) and TNF-${\alpha}$ (0.1-1 mg/ml). Additionally, Careswell significantly inhibited the activation of NF-${\kappa}B$ in PMACI-stimulated HMC-1. Conclusion : Collectively, the findings of this study provide us with a novel insight into the pharmacological actions of Careswell as a potential molecule for use in the treatment of allergic inflammation diseases.

Hijikia fusiforme (HF), a member of brown algae family, exerts various pharmacological effects, including preventing arteriosclerosis and menopausal disorders. This study aimed to elucidate the ameliorative effect of HF on skin inflammation. We investigated the antioxidant and anti-inflammatory effect of HF extract to evaluate its potential as a functional materials. The antioxidant activity of HF was determined using 2,2-diphenyl-1-picrylhydrazy (DPPH) scavenging and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS+) scavenging. To determine the pharmacological mechanism of HF in inflammatory reaction, we evaluated the effects of HF on interleukin (IL)-8, IL-6 and tumor necrosis factor (TNF)-α production and nuclear factor-κB (NF-κB) activation in activated- human mast cells (HMC)-1. Results showed that HF had the high DPPH and ABTS+ radical scavenging activity, and it suppressed IL-8, IL-6 and TNF-α production in a concentration-dependent manner. Moreover, HF significantly ameliorated NF-kB activation in activated-HMC-1. Hence, these results provide evidence that HF's potential for skin inflammation therapy.

Inflammation plays an important role in immune system's response to tissue injury and biological stimuli. However, excessive inflammation can cause tissue damage. Therefore, the development of naturally derived anti-inflammatory agents have received broad attention. In this study, we investigated the anti-inflammatory mechanism of Rubi Fructus (RF) extract on the mast cell-mediated inflammatory response. To determine the regulatory mechanism of RF in inflammatory reaction, we evaluated the effects of RF on secretion of interleukin (IL)-8, IL-6 and tumor necrosis factor (TNF)-α and activation of nuclear factor-κB (NF-κB) and caspase-1 in activated human mast cells-1 (HMC-1). The results showed that RF attenuated IL-8, IL-6 and TNF-α secretion in a concentration-dependent manner. Moreover, RF significantly attenuated caspase-1and NF-κB activation in activated HMC-1. Conclusively, the present results provide evidence that RF may be a promising agent for anti-inflammatory therapy.

Cnidium monnieri (L). Cussion is used as a tonic agent in traditional oriental medicine. However, the molecular mechanism of mast cell-mediated anti-inflammatory modulation has not been fully understood. The aim of the present study was to demonstrate the effects of Cnidium monnieri (L). Cussion eathyl acetate fraction on the expression of pro-inflammatory cytokines, as well as to elucidate its mechanism of action in the human mast cell line (HMC-1). Cells were stimulated with phorbol 12-myristate 13-acetate (PMA) plus A23187 in the presence or absence of Cnidium monnieri (L). Cussion eathyl acetate fraction. Cnidium monnieri (L). Cussion eathyl acetate fraction significantly inhibited the PMA plus A23187-induction of inflammatory cytokines such as tumor necrosis factor (TNF)-$\alpha$, interleukin (IL)-6 and IL-8. Moreover, EtOAc fraction attenuated cyclooxygenase (COX)-2 expression. In activated HMC-1 cells, phosphorylation of extra-signal response kinase (ERK) 1/2 decreased after treatment with EtOAc fraction. Moreover EtOAc fraction inhibited PMA plus A23187-induced nuclear factor (NF)-${\kappa}B$ activation, $I{\kappa}B$ degradation. EtOAc fraction suppressed the expression of TNF-$\alpha$, IL-6, IL-8 through a decrease in the ERK 1/2, as well as activation of NF-${\kappa}B$. These results indicated that Cnidium monnieri (L). Cussion EtOAc fraction exerted a regulatory effect on inflammatory reactions mediated by mast cells.

Objective : To investigate the effect between Fructus Immaturus Ponciri (FIP, the immature fruit of Poncirus trifoliata) and Fructus Ponciri (FP, the ripe fruit of Poncirus trifoliata) on mast cell-mediated immediate-type allergic reactions. Methods : We performed anaphylactic reaction, histamine release, cAMP, $TNF-{\alpha}$, IgE. Results : The aqueous extract of FIP dose-dependently inhibited systemic and local allergic reaction was induced by compound 48/80 or anti-dinitrophenyl (DNP) IgE in a murine model. FIP also significantly inhibited mast cell-dependent ear swelling response induced by topical application of compound 48/80. When mice were orally pretreated with FIP, the plasma histamine levels were reduced in a dose-dependent manner. FIP dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMCs) was activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMCs, when FIP was added, increased compared with that of a normal or control. In addition, FIP had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-a ($TNF-{\alpha}$) production from the RPMCs and IgE produced by lipopolysaccharide-stimulated murine whole spleen cells or U266B1 as human IgE-bearing B cells. However, FP showed the lower inhibition rate than those of FIP in above all allergic reactions. Conclusion : These data have important implications for our understanding of the clinical effects of FIP and FP on allergic diseases, and FIP is more effective than FP on the allergic reaction.

Objective: Danguieumja-gagambang (DGEJGB), a traditional Korean prescription, has been used as therapeutics for allergic diseases such as atopic dermatitis (AD). In this study, we compared with regulatory Effect of Atopic Allergic Reaction by Prescriptions A and by Prescriptions B. Methods : To evaluate and compare the atopic allergic effectiveness of two prescription (A, B) of DGEJGB, the author investigated a possible effect of DGEJGB on mast cell-mediated allergic reaction, cytokine secretion and mRNA expression in vivo and in vitro. Results : Mast cells are a potent source of mediators that regulate the inflammatory response in allergic reaction. In mice orally administered A, B of DGEJGB ( 0.1, 0.1 and 1.0 g/kg) for 1 h, compound 48/80-induced ear swelling was significantly reduced. Significant reduced levels (P < 0.05). of tumor necrosis factor $(TNF)-{\alpha}$ was observed in the human mast cell line (HMC-1) with DGEJGB (A). IL-6 and IL-8 secretion were significantly inhibited by DGEJGB (A, B). In addition, $TNF-{\alpha}$ and IL-8 mRNA expression were reduced by DGEJGB (A) at the dose of 0.01 mg/ml without cell toxicity. Conclusions : These results suggest that DGEJGB (A) contributes to the treatment of atopic allergic reactions rather than DGEJGB (B), and that its action may be due to inhibition of cytokine secretion and mRNA expression HMC-1.

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.
