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.

This study investigated the role of Panax ginseng (PG) on the phorbol myristate acetate (PMA) + calcium ionophore A23187-induced hypoxia-inducible factor-$1{\alpha}$ (HIF-$1{\alpha}$) activation, phosphorylation of the extracellular signal-regulated kinase (ERK), and inflammatory cytokine production from the human mast cell line, HMC-1. HIF-$1{\alpha}$ and phosphorylation of ERK were observed by Western blotting. The inflammatory cytokine production was determined by enzyme-linked immunosorbent assay. PG inhibited the PMA+A23187-induced HIF-$1{\alpha}$ expression and the subsequent production of vascular endothelial growth factor. In addition, PG suppressed PMA + A23187-induced phosphorylation of ERK. We also show that the increased cytokines interleukin (IL)-$1{\beta}$, IL-6, and tumour necrosis factor-${\alpha}$ level was significantly inhibited by treatment of PG. In the present study, we report for the first time that PG is an inhibitor of HIF-$1{\alpha}$ and cytokines on the mast cell-mediated inflammatory responses.

Typha orientalis' stem (TOS) is traditionally used as an herbal medicine for difficulty in urination, galactophoritis purulenta, whooping cough, and allergic dermatitis. However, its effect in experimental models remains unknown. Here, we report the effect of TOS on the phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-induced inflammatory cytokine production and extracellular signal-regulated kinase (ERK) activation in the human mast cell line, HMC-1. TOS inhibited PMA plus A23187-induced cytokines such as tumor necrosis factor-alpha (TNF-$\alpha$) and interleukin (IL)-6. Maximal inhibition rate of TNF-$\alpha$ and IL-6 production by TOS (1 mg/ml) was about 44.02%, and 45.20%, respectively (P < 0.05). In addition, TOS inhibited the expression of TNF-$\alpha$ and IL-6 mRNA under the same condition. Moreover, TOS partially blocked PMA plus A23187-induced ERK phosphorylation. These results suggested TOS could inhibit the cytokine production through blocking of ERK activity.

Objective : Atractyloides Chinensis Rhizome (ACR) is widely used in oriental medicine as a remedy for an inflammation and an allergic disease. However, as yet there is no clear explanation of how ACR affects the production of inflammatory cytokine. This study was to determine the effects of ACR on the mast cell-mediated inflammatory responses. Method : 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 ACR was measured. The TNF-${\alpha}$ protein levels were analysised by Western blots. 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 examined by Western blot analysis. The NF-${\kappa}$B promoter activity was examined by a luciferase assay. Results : 1. The expressions of TNF-${\alpha}$ and TNF-${\alpha}$ mRNA were decreased dose-dependently at 0.05-0.2mg/$m\ell$ of ACR and significantly decreased at 0.2mg/$m\ell$. 2. The expressions of IL-6 and IL-6 mRNA were decreased dose-dependently at 0.05-0.2mg/$m\ell$ of ACR and significantly decreased at 0.2mg/$m\ell$. 3. The expressions of IL-8 and IL-8 mRNA were decreased dose-dependently at 0.05-0.2mg/$m\ell$ of ACR and significantly decreased at 0.2mg/$m\ell$ specially. 4. The expressions of Phosphorylated-JNK were decreased, not p38, ERK 5. The expressions of NF-${\kappa}$B were decreased dose-dependently at 0.1-0.2mg/$m\ell$ of ACR. The expressions of Phosphorylated I${\kappa}$B were significantly decreased at 0.2mg/$m\ell$. In addition, ACR suppressed PMA plus A23187-induced NF-${\kappa}$B promoting activity. Conclusion : It is suggested that ACR should suppress through inhibition of NF-${\kappa}$B activity and cytokine production.

Gamisaenghyeolyunbueum (GSYE) is a traditional Oriental herbal medicine prescription, which has been used for the treatment of various allergic disorders, atopic dermatitis, extravasated bleeding from skin, especially skin related disease. The author investigated the effects of GSYE on mast cell-mediated allergic inflammatory reactions. GSYE dose-dependently (0.01-1 g/kg) inhibited compound 48180-induced systemic anaphylactic shock and ear swelling response. The inhibitory effect of GSYE on the histamine release from rat peritoneal mast cells induced by compound 48f80 reveals significantly (p<0.05) at concentrations ranging from 0.01 to 1 mg/ml in a dose-dependent manner. GSYE also inhibited the passive cutaneous anaphylaxis(PCA) by oral administration at 1 g/kg. In addition, GSYE dose-dependently (0.01-1 g/kg) inhibited the phorbol 12-myristate 13-acetate(PMA) and A23187-induced tumor necrosis $factor-{\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that GSYE may be a beneficial applicability in the allergic-related diseases.

결명자(Cassia obtusifolia) 및 포공영(Taraxacum platycarpum), 유근피(Ulmus macrocarpa)로 제조된 생약재 추출혼합물이 in vitro와 in vivo상에서 아토피 피부염에 미치는 영향을 실험하였다. HMC-1 cell을 이용하여 비만세포의 $\beta$-hexosaminidase 방출량을 측정한 결과, 단일 추출물보다 추출복합물이 탈과립을 억제하는 효과가 우수한 것으로 측정되었다. 그리고 HMC-1 cell에서 PMA와 A23187로 자극하였을 때 생성되는 염증성 cytokine의 분비에서도 추출혼합물의 저해 효과가 가장 높게 나타났다. 아토피 질환모델인 NC/Nga 마우스를 사용하여 생약재 추출혼합물의 아토피 저감효과를 측정한 결과, 진드기 추출물에 의해 발진된 마우스의 귀두께 및 조직학적인 부종 관찰을 통해 생약재 추출혼합물 농도가 증가함에 따라 대조군에 비해 귀 두께 및 부종의 감소가 관찰되었다. 또한 마우스의 혈중 IgE 농도와 이와 관련된 cytokine의 농도를 측정한 결과, 생약재 추출혼합물 투여농도가 증가함에 따라 IgE의 농도가 유의적으로 감소하였고, IgE의 과발현을 유도하는 IL-4의 분비 억제 및 IFN-$\gamma$의 분비가 증가되는 것으로 나타나 생약재 혼합추출물의 섭취가 아토피 피부염 증세 완화 효과에 도움이 되리라 사료된다.

This study confirmed the cytotoxicity and anti-inflammatory activities of natural herbal extracts (HE) including Eucommia ulimoides and Ulmus davidiana against human mast cell (HMC-1). HE was extracted with distilled water (at $75^{\circ}C$) and then freeze-dried for 5 days. Finally, the HE was sterilized by gamma radiation with $^{60}Co$ ${\gamma}$ source at room temperature. Cytotoxicity of the HE against HMC-1 cell was measured using cell counting kit-8 (CCK-8) assay. In addition, inflammatory cytokines such as $TNF-{\alpha}$, IL-6 and IL-8 were evaluated by ELISA kit on the HMC-1 cells with calcimycin A23187 and phorbol 12-myristate 13-acetate (PMA). The results showed that HE had no toxicity and reduced $TNF-{\alpha}$, IL-6, IL-8 response on HMC-1 cells.

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.

Citrus unshiu (Rutaceae) has long been known as an anti-inflammatory and anti-allergic agent. In the present study, the inhibitory effect of CUWE (Citus unshiu water extract) on the production of $TNF-{\alpha}$ and tryptase was examined. In addition, a possible mechanism for the inhibition of trypsin-stimulated human leukemic mast cell-1 (HMC- 1 ) activation was determined. To do so, $TNF-{\alpha}$ production from the HMC-1 cells that were stimulated by trypsin (100 nM) in the presence or absence of CUWE $(10,\;100,\;and\;100\;{\mu}g/ml)$ was measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-PCR. The tryptase production was evaluated by reverse transcription-PCR. Extracellular signal-regulated kinase (ERK) activation was analyzed by Western blot. Trypsin activity was measured by using Bz-DL-Arg-p-nitroanilide (BAPNA) as substrate. Results showed that the CUWE inhibited production of both $TNF-{\alpha}$ and tryptase from the trypsin-stimulated HMC-1 in a dose-dependent manner. The CUWE a1so inhibited the ERK phosphorylation and trysin activity. These results indicate that the CUWE had an inhibitory effect on $TNF-{\alpha}$ and the tryptase productions by blocking the ERK phosphorylation and trypsin activity.
