  • Objectives : The purpose of this study is to examine of the effect of Kami-chungsimyeunjatang(KCSYJT) medicine on the atopy eruption control. Methods : The expression of IgE, IL-4, IL-6, $TNF-{\alpha}$, IgG2b, IgM, IgG2a and IgG1 level in serum, and $IFN-{\gamma}$ production by KCSYJT were analyzed. CD3e+/CD69+, CD4+/CD25+, B220+/IgE+ and B220+/CD23+ positive cells by flow cytometry in splenocytes were assayed and the revelation of CD3e+/CD69+, CD4+/CD8+ and CD4+/CD25+ marker in PBMC, spleen and DLN were observed. The outturn of IL-4, eotaxin 2, CCR3, TARC mRNA in splenocytes werw observed. We also analyzed NC/Nga mice's ear, DLN and neck-back skin after biopy and dye by H&E, and toluidine staining (mast cells marker) method, measured about epidermis and dermis part in comparison with control group. Results : NC/Nga mice suffered from dermatitis very similar to human AD with IgE hyperproduction. Specially, result that measure IgE content in serum on 8 weeks, 12 weeks, 16 weeks decreased remarkably than control group. After experiment end, result that observe revelation CD3e+/CD69+, CD4+/CD8+ and CD4+/CD25+ marker in PBMC, spleen and DLN establishment observed recover as normal with political background. And decreased than result control group which measure IL-4, IL-6, $TNF-{\alpha}$, IgG2b, IgM, IgG2a, IgG1 level in serum, and $IFN-{\gamma}$ production secreted in Th1 cell displayed increase by KCSYJT medicines. Ear thickness decrease than control group in result that observe effect that get in ear of a NC/Nga mouse. Course inflammation immunocyte etc.. permeated of result that effect that KCSYJT medicines get to NC/Nga mouse's skin establishment analyzes ear, DLN and neck-back skin after biopy, and dye by H&E, and toluidine staining (mast cells marker) method decreased about epidermis. and inflammation of dermis part remarkably than control group. Immunohistochemical examination of the skin lesion showed decrease by KCSYJT medicines on numbers of mast cells (CCR3) and CD4+ T cells containing IL-4 necessary for IgE. Conclusions : Th1 cell and Th2 cell was observed to be shift by secretion amount of IL-4 and $IFN-{\gamma}$ by KCSYJT medicines. Therefore, the KCSYJT medicine turned out to be useful in allergy autoimmune disease.

  • Objective : Soybeans of Canavalia gladiata(CG) and root of Arctium lappa(AL) have been reported to have anti-inflammatory, antioxidant effect. However, the immunoregulatory mechanisms of its combinational prescription remain a matter of considerable debate. In the current study, we investigated whether CG and AL and its combinational prescription(CG+AL) regulate immune system using chronic immobilization-stress mouse model. Methods : C57BL/6J mice fixed for 2 hours into immobilization tube after CG, AL, CG+AL oral administration after 2 hours daily for 21 days. After every experiment has ended the C57BL/6J mice were sacrificed on 22 days. The production of Serotonin and Cortisol, lgA were observed by ELISA method, The proportion of immune cells such as T/B cell and macrophage, NK cell were measured by FACS. Then, Real-time PCR was performed to measure the mRNA expression of Inflammatory cytokines(IL-1beta, IL-6, TNF-a) and T cell activation cytokines(IL-2, IL-10, IFN-gamma, IL-12p35 / p40). Result : When chronic immobilization-stress mouse model were treated with CG+AL(1:4), the expression of mRNA were significantly decreased at the Inflammatory cytokines(IL-1beta, IL-6, TNF-a). While, the levels of mRNA were significantly increased at immune T cell activation cytokines. Additionally, CG+AL(1:4) combinational prescription group enhanced immune cells such as T/B cell and macrophage, NK cell. Furthermore, the Immuno-fluorescence result of brain tissue can confirm that CG+AL(1:4) group significantly increased the BDNF expression. Conclusion : These result suggest that CG+AL(1:4) combinational prescription has Immune System enhancement via stress-mediated immunocyte.

  • The purpose of this study is to examine the effect of herbal medicine complex (HMC) containing Camellia sinensis L., Duchoesna chrysantha, Houttuynia cordata Thunberg, Poncirus trifoliata Rafinesque on skin inflammation and atopic dermatitis. First, we examined the anti-inflammatory effect of HMC in TNF-α induced human keratinocytes (HaCaT cell). Real-time PCR and western blotting were performed to evaluate the expression of inflammatory cytokines (e.g., iNOS, COX-2, IL-6, IL-8) mRNA and protein. Four-weeks old male NC/Nga mice were treated with 1% 2,4-dinitrochlorobenzene (DNCB) solution and used as an atopic dermatitis mice model. And, HMC (200 mg/kg or 400 mg/kg) was administered directly into the stomach of mice for 4 weeks, and blood or serum analysis, tissue staining were performed after oral gavage. As a result HMC inhibited the mRNA expression of iNOS, COX-2, IL-6, and IL-8, which had been increased by TNF-α in HaCaT cells. In addition, the protein expression was also significantly suppressed in the same way as the mRNA expression results. The in vivo experiment results showed that, HMC administration reduced thickening of the epidermis and infiltration of eosinophil into the skin stratum basale compared to DNCB treatment. In addition, HMC administration significantly reduced the inflammatory cytokines (IL-4, IL-5, IL-6, and IL-13) production and immunocyte (white blood cell, lymphocyte, neutrophil, and eosinophil) count compared to DNCB treatment. Moreover, the serum IgE and histamine level was decreased by HMC administration. These results suggest that HMC can be used as effective herbal medicine extract for skin inflammation and atopic dermatitis. And this study may contribute to the development of the herbal medicine-based drug for the treatment of skin inflammation and atopic dermatitis.

  • ${\beta}$-glucan은 균류의 세포벽, 귀리, 효모, 식물의 구성물질로, 면역 세포의 활성, 전염증성 사이토카인 분비, 항암효능과 같은 면역 체계에 중요한 역할을 한다. 면역계는 건강한 몸 상태의 항상성을 유지한다. 하지만, 병원성 물질이 신체 내로 들어오게 되면 면역 항상성이 무너지게 되고, 질병이 유발될 수 있다. 따라서, 본 연구는 ${\beta}$-glucan이 인간 단핵구 THP-1 세포에서 면역 조절 효과에 이용될 수 있는지를 확인하였다. ${\beta}$-glucan은 THP-1 세포에 다양한 농도를 처리하여 배양하였으며, $TNF-{\alpha}$ mRNA 발현과 단백질 수준을 Real-time PCR와 ELISA을 이용하여 분석하였다. 또한 전사 인자 $NF-{\kappa}B$ p50와 MAPKs 신호 기작 활성을 western blot을 이용하여 분석하였다. ${\beta}$-glucan으로 유도된 MAPKs와 $NF-{\kappa}B$ p50 활성이 증가하였다. ${\beta}$-glucan이 인간 단핵구 THP-1 세포에서 $TNF-{\alpha}$ 생성에 의해 면역 증강 효과를 나타내며, 이는 MAPKs와 $NF-{\kappa}B$ p50 신호 전달을 통해 나타내는 것을 제시한다. 종합적으로, 본 연구는 ${\beta}$-glucan이 인간 단핵구 THP-1 세포를 통해 면역 체계를 향상시킬 것이라고 사료된다.

  • 비만세포는 염증 및 알레르기 반응과 관련하여 우리 몸에서 주요한 작용을 하는 세포이다. 봉독은 현재까지 진통기전에 관련된 모델로 연구가 진행되어 왔으나, 최근에는 항염증이나 항알러지반응 둥에서 면역세포와 관련 한 연구가 진행 중에 있다. 본 연구는 봉독의 주요성분인 melittin과 MCD Peptide가 비만세포주에서의 유전자 발현에 미치는 영향을 연구함으로써 향후 유전자 언구에 관련한 기초를 제시하고자 하였다. 본 연구에서는 사람의 비만세포주를 이용하여, 세포독성 실험을 거쳐서 얻은 유효농도에서 각각 melittin과 MCD Peptide를 처치하고, 이때 변화하는 유전자의 발현양상을 microarray분석기법을 통하여 정보를 얻었다. 실험적 통계에 의하여 global M이 1 또는 -1 이상인 것을 유의한 것으로 보았을 때, melittin에서는 모두 7개 의 유전자가 항진되고, 8개의 유전자가 어제되었다. MCDP에서는 7개의 유전자가 항진되고 17개의 유전자가 억제되었다. 이들 유전자들이 주로 관련하는 체내의 작용은 세포내에서 단백결합, lymphocyte 기능의 활성화, macrophage 항원관련 및 세포핵의 수용체, GABA A receptor 관련물질, cAMP 반응요소와 연관된 단백질, 보체계 8번 및 B-cell 관련물질, 다낭성 신질환에 관련된 단백물질, 염증관련물질, 혈액응고에 영향을 주는 단백물질등과 연관이 되었다. 이러한 분석결과를 통하여 동복에서의 주요약리작용을 담당하는 melittin과 MCD peptide의 작용기전을 밝히는데 보다 유용한 자료를 얻을 수 있었으며, 향후에 봉독의 주요성분 및 전체봉 독액이 항알레르기반응이나 항염증작용에 미치는 영향에 대한 심도있는 연구가 필요할 것으로 사료된다.
