Objective : We wished to examine closely effect that Kami-JeSeubUilYeongTang medicines used to atopy dermatitis disease patient get in atopy eruption control experimentally. Materials and Methods : Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen specially in childhood, association with IgE hyperproduction and precipitation by environmental factors. However, the exact etiology of AD has been unclear. To further explore the pathogenesis and treatment of AD, a suitable animal model is required. We found that skin lesions, which were clinically and histologically very similar to human AD, mite antigen-induced dermatitis on the face, neck, ears and dorsal skin of inbred NC/Nga mice. Result and Conclusion : Kami-jeseupwiryeongtang(JWRTK) medicines controlled CD3+/CD69+, CD4+/CD25+, B220+/IgE+, and B220+/CD23+ revelation that an experiment that motive allergy immune reponse because an in vitro experiment stimulates splenocytes of a NC/Nga mouse same time by PWM, and interleukin-4, eotaxin 2, CCR3, TARC mRNA outturn that bear in splenocytes decreased remarkably by Jeseupwiryeongtang-Kamibang(JWRTK) medicines. Th1 cell and Th2 cell observe to be shifted by secretion amount of IL-4 and IFN-$\gamma$ by Jeseupwiryeongtang-Kamibang(JWRTK) medicines could know that Jeseupwiryeongtang-Kamibang(JWRTK) medicines can use usefully in allergy autoimmnune diease.

Background and Objective: The importance of the presence of eosinophils in the airways of patients with fetal asthma has long been recognized, but the mechanism by which these cells are recruited and retained in the lung are only now being elucidated. Eotaxin is a potent and specific eosinophil chemoattractant that is mobilized in the respiratory epithelium after allergic stimulation. Material and Methods: We used water extracts of Liripois Tuber and pulmonary epithelial cell lines A549(human typeII-like epithelial cells) and human eosinophils. We estimated cytotoxic effects of Liripois Tuber via MTS assay, and estimated the effects of Liripois Tuber on chemokines from prestimulated A549 cells by sandwich ELISA and RT-PCR. We conducted chemotaxis assay on prestimulated eosinophils treated with Liripois Tuber. Result: In this study we demonstrated that $TNF-{\alpha}$, IL-4 and $IL-1{\beta}$ induced the accumulation of chemokines mRNA in the pulmonary epithelial cell lines A549 in dose-dependent manner. Chemokines were inhibited by Liripois Tuber in dose-dependent manner. The eosinophil migration was inhibited at high concentration of Liripois Tuber. Conculusion: These findings indicate that the supression of the expression of chemokines can be accomplished by Liripois Tuber treatment, raising the possibility that Liripois Tuber might be of therapeutic value in diseases such as asthma.

This study aimed to evaluate the anti-asthmatic effects of Seonpye-tang (SPT) using OVA-induced asthmatic mice model. Scavenging activity of SPT on DPPH free radical and SOD-like activity of SPT were measured at final concentration 62.5, 125, 250, 500 (${\mu}g/m{\ell}$), RBL-2H3 cells were treated with DNP IgE for 24hr, and treated with SPT (1, 10, 100 ${\mu}g/m{\ell}$) for 1hr, followed by treatment with DNP-HSA for 1hr at $37^{\circ}C$. The level of IL-4 and TNF-${\alpha}$ were measured by ELISA. Asthmatic mice model was conducted by repeated challenge of OVA using C57BL/6 mice. Each group was treated with distilled water, SPT (400 mg/kg and 200 mg/kg) extract or cyclosporin A (10 mg/kg) for the later 8 weeks. Immune cells subpopulation, eotaxin, IL-5 and TNF-${\alpha}$ in BALF were analyzed. SPT dose-dependently increased Scavenging activity on DPPH free radical and SOD-like activity. SPT significantly ameliorated the increase of total cells number and eosinophil including of immune cell subpopulation of $CD3^+/CD69^+$, $CCR3^+$, $B220^+/CD22^+$, $B220^+/CD45^+$ and $B220^+/IgE^+$ cells in BALF comparing to control group. Eotaxin and IL-5 level in BALF were significantly decreased by SPT. These results strongly suggest that SPT would be a effective candidate for herbal-originated anti-asthmatic drug. However, this drug should be further studied for characterization of the accurate action and underlying mechanisms using variant disease model in the future.

Objectives : The purpose of this study is to investigate the effect of Bacillus-fermented Scutellariae Radix acupuncture solution (SB) on chemokine and growth factor production in RAW 264.7 mouse macrophages stimulated by lipopolysaccharide (LPS). Methods : Productions of chemokine and growth factor were measured by High-throughput Multiplex Bead based Assay with Bio-plex Suspension Array System based on xMAP$^{(R)}$ technology. Firstly, cell culture supernatant was obtained after treatment with LPS (1 ${\mu}g$/mL) and SB for 24 hours. Then, it was incubated with the antibody-conjugated beads for 30 minutes. Detection antibody was then added and incubated for 30 minutes. After incubated for 30 minutes, strepavidin-conjugated phycoerythrin (SAPE) was added. After another 30 minutes incubation, the level of SAPE fluorescence was analyzed in Bio-plex Suspension Array System. Results : The results of the experiment are as follows. 1. SB significantly inhibited the LPS-induced production of vascular endothelial growth factor (VEGF), interferon-inducible protein (IP)-10, and granulocyte-colony stimulating factor (G-CSF) at the concentration of 25, 50, 100, and 200 ${\mu}g$/mL in RAW 264.7 cells (P < 0.05). 2. SB significantly inhibited the LPS-induced production of Eotaxin at the concentration of 25, 100, and 200 ${\mu}g$/mL in RAW 264.7 cells (P < 0.05). 3. SB significantly inhibited the LPS-induced production of MIP-$1\alpha$ at the concentration of 25 and 100 ${\mu}g$/mL in RAW 264.7 cells (P < 0.05). Conclusions : These results suggest that SB has immuno-modulatory property related with its inhibition of VEGF, IP-10, G-CSF, and Eotaxin production in macrophages.

Objectives : The present study was to investigate the effect of extract of Chelidonii herba (ECH) on the proliferation and activation of eosinophils which were prepared from lung cells of asthma-induced mouse by ovalbumin (OVA) treatment. Methods : C57BL/6 mouse was exposed to OVA three times a week for 6 weeks. The mouse lung tissues were dissected out, chopped and dossiciated with collagenase (1 ${\mu}g$/ml). Eosinophils were activated by rIL-3/rmIL-5 co-treatments. The lung cells were treated with ECH, incubated for 48 hr at $37^{\circ}C$, and analyzed by flow cytometery, ELISA, RT-PCR, and immuno-histochemical analysis. Results : In FACS analysis, number of granulocyte/lymphocyte, $CD3e^-$/$CCR3^+$, $CD3e^+$/$CD69^+$, $CD4^+$ and $CD23^+$/$B220^+$ in asthma-induced lung cells were significantly decreased by ECH treatment compared to the control group. And mRNA expression for IL-4, IL-5, IL-13, CCR3 and eotaxin in asthma-induced lung cells, which was induced by rIL-3 plus rmIL-5 treatments, was significantly decreased by ECH treatment. In ELISA analysis, production levels of IL-3, IL-5, IL-13 and histamine in asthma-induced lung cells, which were induced by rIL-3 plus rmIL-5 co-treatment, were significantly decreased by ECH treatment. ECH treatments significantly inhibited the proliferation of eosinohils prepared from asthma-induced mouse lung tissues compared to the non-ECH treated control cells. Immunohistochemical analysis revealed that ECH treatment significantly decreased the levels of eosipnphil activation compared to non-treated cells. Conclusions : The present data suggested that Chelidonium majus L. may have an effect on the inhibition of parameters associated with asthma responses in eosinpophils, and thus implicate the possibility for the clinical application of Chelidonium majus L.

Leptin is an adipocyte-secreted hormone and its plasma levels correlate with total body fat mass, however, it also plays a regulatory role in immunity, inflammation, and hematopoiesis. Chemokine is known as a chemoattractant cytokine in inflammatory reaction, but its role in leptin reaction has not been well studied. In this study, the direct effect of leptin on the expression of chemokine mRNAs and lipopolysaccharide (LPS)-induced chemokine KC mRNA in mouse peritoneal macrophages was investigated. Leptin did not induce the expression of lymphotactin, RANTES, eotaxin, MIP-1$\beta$, MIP-1$\alpha$, MIP-2, MCP-1, IP-10, TCA-3, and KC mRNA in mouse peritoneal macrophages, and had no direct effect on the expression of these LPS-induced chemokine mRNAs except KC mRNA. The synergistic effect of leptin on the expression of LPS-induced KC mRNA occurred late in the time course of response to LPS. The increased expressions of Ob-Rb mRNA and leptin receptor protein were detected during the LPS treatment. Leptin produced a substantial increase in the stability of the LPS-induced KC mRNA, and the synergistic effect of leptin on LPS-induced KC mRNA expression was further augmented by cycloheximide (CHX). Pyrrolidine dithiocarbamate (PDTC) did not block the synergistic effect of leptin on LPS-induced KC mRNA expression in mouse peritoneal macrophages. These data suggest that although leptin has no direct effect on the expression of lymphotactin, RANTES, eotaxin, MIP-1$\beta$, MIP-1$\alpha$, MIP-2, MCP-1, IP-10, TCA-3, and KC mRNA in mouse peritoneal macrophages, the synergistic effect of leptin on the expression of LPS-induced KC mRNA has the possibility that LPS might induce the expression of the Ob-Rb receptor or an unknown gene(s) that sensitizes macrophages to the synergistic function of leptin. Therefore, further studies are necessary to examine leptin as a regulatory factor of chemokine production.

대부분의 알려진 알러젠들은 단백분해효소의 성격을 가지고 있고 이는 알레르기 반응에서 Th2 면역 반응을 일으키는 데 중요한 역할을 하는 것으로 알려져 있다. 이러한 단백분해효소들과 반응하는 것으로 알려진 protease activated receptor (PAR) 는 4가지 종류가 있으며, 이 중 PAR2의 경우 알레르기 질환과 많은 상관관계를 보여 많은 연구가 되고 있다. 본 연구는 Aspergillus protease 알러젠에 의한 초기 및 만성 Th2 면역반응에서 PAR2 의 역할을 규명하기 위해 Aspergillus protease 알러젠으로 정상쥐와 PAR2 유전자 결핍쥐 모두 Th2 반응을 유도한 후 면역세포의 침윤 정도 및 Th2 관련 cytokine 및 chemokine 유전자들의 발현 정도를 비교하였다. 그 결과 Aspergillus protease 알러젠으로 비강내로 1회 처리했을 경우 중성구의 침윤이 두드러지는데, 이때 PAR2 결핍 마우스는 이러한 면역세포의 침윤이 유의적으로 감소하였다. 또한, 이와 관련된 IL-25, TSLP, Eotaxin 유전자들의 발현 역시 PAR2 결핍 마우스에 현저히 감소하였다. 한편, Aspergillus protease 알러젠으로 비강내로 6회 처리했을 경우 중성구 대신 호산구의 침윤이 두드러지지만 PAR2 결핍 마우스에서 그 정도가 유의적으로 낮았다. OVA 특이 IgE와 IgG1 농도 역시 현저하게 PAR2 결핍 마우스에서 낮았고, CCL21의 발현이 PAR2 결핍마우스 MEF cells에서 현저히 감소하였다. Th2 초기 면역반응에서 가장 중요한 IL-25의 발현에 MAKP p38 pathway가 관여한다는 것을 이번 연구에서 알 수 있다. 본 연구를 통해 Aspergillus protease 알러젠으로 유도된 알러지성 기관지 염증 반응에서 초기 반응뿐만 아니라 만성반응에서도 PAR2가 중요한 것을 알 수 있다.

Objective: The aims of this study were to analyze deficiency-excess pattern identification and to compare the blood cytokines in patients with asthma. Methods: A total of 112 patients with asthma who met the inclusion and exclusion criteria were divided into deficiency syndrome and excess syndrome groups. Blood was examined for eotaxin, interleukin (IL)-1β, IL-4, IL-5, IL-6, IL-13, and tumor necrosis factor (TNF)-α. The Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA), a Visual Analogue Scale (VAS), and heart rate variability (HRV) tests were administered to both groups. Results: Pattern identification divided the 112 patients into two categories: a deficiency syndrome group (N=52) and an excess syndrome group (N=60). Analysis of blood cytokines showed higher levels of IL-4, IL-5, and IL-13 in the deficient pattern than in the excess pattern group, but the difference was not statistically significant. Analysis of the HRV revealed a significantly higher mean value for the very-low-frequency (VLF) and high-frequency (HF) bands in the deficiency than in the excess syndrome group. The morbidity duration was longer in the deficiency than in the excess syndrome group, but the difference was not statistically significant. Analysis of the QLQAKA and VAS scores showed a negative correlation, whereas BMI and VAS showed a positive correlation. Conclusions: Levels of blood cytokines, including eotaxin, IL-1β, IL-4, IL-5, IL-6, IL-13, and TNF-α, did not differ statistically between the deficiency and excess syndrome groups. The development of a more accurate asthma-specific pattern identification tool would be useful in asthma control.

The number of patient with allergic asthma and atopy have increased in the cities of Korea steadily. In order to elucidate the primary factor, we investigated whether the house dust particles collected from an apartment of the middle classes has promoting effects of allergen-related airway inflammation and airway hyperresponsiveness. Mice were treated with 0.1 mL of 1 mg/mL of house dust particles suspension by intratracheal instillation once weekly for 10 weeks combined with ovalalbumin (OVA) sensitization. Intratracheal instillation of house dust particles and OVA sensitization caused an increase in the level of serum L-lactate dehydrogenase (LDH), immunoglobulun-E (IgE) and histamine, and an elevation in respiratory resistance. It also enhanced infiltration of eosinophils in the bronchoalveolar lavage fluid (BALF) of mice, IgE and eotaxin expression in blood, and T helper type 2 cell derived cytokine levels such as of interleukin (IL)-4, IL-13 and IL-5 in the BALF. However, it did not influence T helper type 1 cytokine such as interferon-gamma in the BALF. These results indicate that house dust particles elevate allergen-related airway inflammation and airway hyperresponsiveness in mice and may play an important role in the aggravation of asthma and atopy in Korea.
