Objectives : In this study, we investigated the effect of Cassia obtusifolia Linne (Cassiae Semen; CS) extract on ovalbumin (OVA)-induced allergic asthma in mice. Methods : CR was extracted with 70% ethanol. For in vitro study, HMC-1, human mast cells were treated with CS extract at 0.2 and $0.5mg/m{\ell}$ for 1 h, and then stimulated with compound (C) 48/80 for 30 min. Primary spleenocytes were isolated from the spleen of mice, treated with CS extract for 1 h, and then stimulated with ConA for 24 h. For in vivo study, mice were sensitized at day 0, 7 and 14 with 0.2% OVA and then airway challenged using neublizer at day 21, 23, 25, and 27 to induced allergic asthma. CS extract at doses of 100 and 300 mg/kg body weight was orally administered during OVA challenge once per a day. The levels of allergic mediators such as histamine, OVA-specific IgE, IL-4, and $IFN-{\gamma}$ were measured in the sera of mice or culture supernatants by EIA and ELISA, respectively. The expression of IL-4 and $IFN-{\gamma}$ gene was determined by RT-PCR. The histopathological change of lung tissues was observed with hematoxylin and eosin (H&E) and Periodic acid Schiff (PAS) staining. Results : The treatment of CS extract in HMC-1 cells significantly inhibited C48/80-induced degranulation, and histamine release. The treatment of CS extract in spleenocytes suppressed the expression of IL-4 and $IFN-{\gamma}$ mRNA. The administration of CS extract in OVA-induced asthmatic mice significantly decreased the levels of OVA-specific IgE, and IL-4 in a dose-dependent manner with OVA-control group. In addition, CS extract inhibited the infiltration of inflammatory cells and bronchiolar damage with epithelial thickening in lung tissues of OVA-induced asthma mice, and also mucin accumulation. Conclusions : These results indicate that CS extract prevents asthmatic damage through regulating the allergic immune response.

Objectives: For the risk management of airborne fungal diseases, our aim was to evaluate airborne fungi and study the toxicity associated with fungal allergic diseases using fungal species native to Korea. Methods: Fungi were isolated from outdoor air samples collected from Seoul, Incheon, Cheonan, Gwangju, Ulsan, Busan, and Jeju and tested for their cytotoxicity potential and their ability to induce proliferation and secretion of macrophage-derived chemokine (MDC) in human mast cells (HMC-1). Results: More than 18 species of fungi were collected from outdoor air in Korea over one year, and the strains were identified and systematically analyzed. The results showed that the Cladosporium (59%) and Alternaria (22%) strains are the most common in outdoor air. Three of the collected strains (Fusarium, Trichoderma, and Penicillium) showed mild toxicity in cells involved in allergic inflammation, and twelve induced cell proliferation in HMC-1 cells. More importantly, many strains (Edgeworthia, Trametes, Emmia, Irpex, Talaromyces, Penicillium, Periconia, Epicocum, Bipolaris) induced the MDC protein in activated HMC-1 cells. Conclusion: Nineteen percent of the tested strains caused cytotoxicity in mast cell lines, whereas, most of the non-toxic strains contributed to cell activity. Among the tested strains, more than 80% increased the expression of MDC protein, which contributes to the severity of atopic dermatitis, asthma, and rhinitis. It is, in fact, one of the markers for these conditions. Therefore, airborne fungus could be considered as an important marker for environmental risk management for allergic diseases in Korea.

방사선에 대한 방호와 면역기능 조절을 목적으로 새로운 생약복합조성물인 HemoHIM을 개발하였다. 식품 원료로 사용 가능한 생약재 3종 당귀, 천궁, 백작약의 에탄올 분획을 열수추출물에 첨가하여 HemoHIM을 제조하였다. HemoHIM의 항알레르기 효과를 검증하기 위하여 사람 비만세포주 HMC-1을 사용해 compound 48/80으로 유도되는 히스타민 분비량과 PMA/A23187로 유도되는 염증성 사이토카인의 분비량을 측정하였다. 히스타민의 양은 형광분석법으로, 염증성 사이토카인 IL-6, IL-8, TNF-$\alpha$, GM-CSF의 양은 효소결합 면역측정법으로 측정하였다. 저농도의 HemoHIM에 의해 히스타민 분비량이 억제되었고, 모든 농도에서 IL-6, TNF-$\alpha$, GM-CSF의 분비량은 억제되었지만 IL-8은 고농도에서만 억제되었다. 사이토카인의 mRNA 발현량은 HemoHIM의 농도 의존적으로 억제되었다. 그리고 c-kit와 Fc$\varepsilon$RI의 mRNA 발현량도 모든 농도에서 억제되었지만, tryptase의 mRNA 발현량은 저 농도에서만 억제되었다. 이상의 결과로 HemoHIM이 비만세포의 활성을 억제하는 효과가 있다는 것을 알 수 있었으며, 상대적으로 독성이 적은 항알레르기 제재로 개발할 가능성을 제시한 것으로 생각된다.

Mast cells are a potent source of mediators that regulate the inflammatory response in allergic reaction. To evaluate the atopic allergic effect of Asiasari radix(AR), the author investigated a possible effect of AR on mast cell-mediated allergic reaction, cytokines secretion and mRNA expression in vivo and in vitro. In mice orally administered by AR (0.01, 0.1 and 1.0 g/kg) for 1 h, compound 48/80-induced ear swelling was significantly reduced (P < 0.05). AR had inhibitory effects on tumor necrosis factor $(TNF)-{\alpha}$, interleukin (IL)-8, and IL-6 secretion from HMC-1. Significant reduced levels of $TNF-{\alpha}$ mRNA was observed in the human mast cell line (HMC-1) with AR (1.0 mg/ml). In addition, AR had no cytotoxic effect on cell viability. These results suggest that AR contributes to the treatment of atopic allergic reactions, and that its action may be due to inhibition of cytokine secretion and mRNA expression in HMC-1.

The purpose of this study was to investigate the anti-allergy activities of persimmon leaf extract (PLE) on a phthalic anhydride (PA)-induced allergic mouse model. A human leukemic mast cell line (HMC-1) was used to examine the inhibitory activity of PLE on the histamine release by human leukemic mast cells. PLE inhibited histamine release from HMC-1 cells in response to cross-linkage of high-affinity IgE receptor-${\alpha}$ ($Fc{\varepsilon}RI{\alpha}$). Additionally, a PA-induced allergic mouse model was used to investigate the effects of PLE in vivo. Mice were orally administrated with or without PLE of single dose (250 mg/kg/day) for 31 days. Oral intake of PLE significantly inhibited passive cutaneous reactions. Oral administration of PLE to PA-induced allergic mice also led to a striking suppression of the development of contact dermatitis, ear swelling and lymph node weight. In addition, PA-specific IL-4 production of draining lymph node cells was markedly diminished by PLE oral administration, but not IFN-${\gamma}$. Furthermore, PLE treatment suppressed PA-induced thymus and activation-regulated chemokine (CCL17) and cutaneous T cell-attracting chemokine (CCL27) expressions in ear tissues. Based on these results, we suggest that PLE may have therapeutic potential as an effective material for management of irritant contact dermatitis or related inflammatory diseases.

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.

The effect of aqueous extract of Lycopus lucidus Turcz. (Labiatae)(LLAE) on mast cell-mediated immediate-type allergic reactions was investigated. LLAE (0.01 to 1 mg/g) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80. LLAE (0.001 to 1 mg/g) also dose-dependently inhibited local anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. When LLAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. LLAE (0.001 to 1 mg/mι) dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when LLAE (1 mg/mι) was added, significantly was increased, compared with that of normal control. These results provide evidences that LLAE may be beneficial in the treatment of allergic diseases.

Anglicae dahuricae Radix (ADR), the dried roots of Angelica Dahurica Benth et Hook (Umbelliferae), is a traditional herbal medicine used to treat colds, headache, skin diseases such as acne and possess analgesic, antipyretic and drainage effects. In the present study, the author evaluated the effect of ADR on regulation of inflammatory reaction. ADR reduced the ear-swelling responses derived from compound 48/80 in dose-dependent manner significantly. ADR inhibited the PMA plus A23187-induced productions of IL (Interleukin)-8, IL-1β, granulocyte macrophage-colony stimulating factor (GM-CSF) and tumor necrosis factor (TNF)-α from human mast cells (HMC)-1. In addition, ADR blocked PMA plus A23187-induced ERK1/2 phosphorylation. Ⅰ suggest that ADR regulates inflammatory reaction through inhibition of inflammatory cytokines such as IL-8, IL-1β and GM-CSF.
