  • There are detailed descriptions of the clinical experiences and prescriptions of asthma in traditional Korean medicine. Zedoariae rhizoma is one of the Korean herbal medicines used to treat bronchial asthma and allergic rhinitis for centuries. However, the therapeutic mechanisms of this medication are still far from clear, In this study, a house-dust-mite (Dermatophagoides pteronyssinus [Der p])-sensitized murine model of asthma was used to evaluate the immunomodulatory effect of Zedoariae rhizoma on the allergen-induced airway inflammation in asthma. Three different protocols were designed to evaluate the treatment and/or long-term prophylacitic effect of Zedoariae rhizoma in Der p-sensitized mice. Cellular infiltration and T-cell subsets in the bronchoalveolar lavage fluid (BALF)of allergen-challenged mice were analyzed. Intrapulmonary lymphocytes were also isolated to evaluate their response to allergen stimulation. When Zedoariae rhizoma was administered to the sensitized mice before AC (groups A and C), it suppressed airway inflammation by decreasing the number of total cells and eosinophil infiltration in the BALF, and downregulated the allergen- or mitogen-induced intrapulmonary lymphocyte response of sensitized mice as compared to those of controls. This immunomodulatory effect of Zedoariae rhizoma may be exerted through the regulation of T-cell subsets by elevation or activation of the CD8+ and double-negative T-cell population in the lung. However, the administration of Zedoariae rhizoma to sensitized mice 24 h after AC (group B) did not have the same inhibitory effect on the airway inflammation as Zedoariae rhizoma given before AC. Thus, the administration of Zedoariae rhizoma before AC has the immunomodulatory effect of reducing bronchial inflammation in the allergen-sensitized mice. On the other hand, to determine the potentiality of prophylactic and/or therapeutic approaches using a traditional herbal medicine, Zedoariae rhizoma, for the control of allergic disease, we examined the effects of oral administration of Zedoariae rhizoma on a murine model of asthma allergic responses. When oral administration of Zedoariae rhizoma was begun at the induction phase immediately after OVA sensitization, eosinophilia and Th2-type cytokine production in the airway were reduced in OVA-sensitized mice following OVA inhalation. These results suggest that the oral administration of Zedoariae rhizoma dichotomously modulates allergic inflammation in murine model for asthma, thus offering a different approach for the treatment of allergic disorders.

  • This study was done to investigate the effects of Gamisojaganggi-tang(GSGT) on immunopathologic changes in OVA-induced asthma model of mice. Pathologic indicators associated with this immune disease, which include cytokines, the number of immune-cells, immunoglobin E (IgE), were examined, and histological changes of bronchial tissues were also examined. The administration of GSGT significantly reduced the lung weight compared with control mice of OVA-induced asthma model. The administration of GSGT significantly reduced the number of total cells in BALF compared with control mice of OVA-induced asthma model. The administration of GSGT significantly reduced the number of eosinophil in BALF compared with control mice of OVA-induced asthma model. The administration of GSGT insignificantly increased the number of monocyte in BALF compared with control mice of OVA-induced asthma model. The administration of GSGT significantly reduced the number of lymphocyte in BAL compared with control mice of OVA-induced asthma model. The administration of GSGT significantly reduced the gene expression of eotaxin in lung tissue compared with control mice of OVA-induced asthma model. The administration of GSGT insignificantly reduced the IL-4 and IL-5 production in BALF compared with control mice of OVA-induced asthma model. The administration of GSGT insignificantly reduced the levels of total IgE and ovalbumin-specific IgE in BALF. The administration of GSGT significantly reduced the levels of ovalbumin-specific IgE whereas the serum levels of total IgE were insignificantly reduced compared with control mice of OVA-induced asthma model. The administration of GSGT moderately reduced bronchial alveolar narrowing, bronchiovascular edema and increase in the size of alveolar space, which shown in control mice of OVA-induced asthma model, in a dose dependent manner. Furthermore, GSGT reduced invasion of inflammatory cells, and proliferation of smooth muscle cells in bronchial tissue. These results suggested that GSGT has suppressive effects on pathologic changes associated with disease progression in asthma through the modulation of immune system. GSGT has potential to use as an anti-asthmatic agents.

  • We hope to evaluate the effects of Sabaek-san for the bronchial asthma using assesment on the metrix metalloproteinase-9(MMP-9) after Sabaek-san was intravenously administered OVA-sensitized and -challenged mice. Seventy-two female mice, 8-10 weeks of age and free of murine specific pathogens, were used. Of the seventy-two mice, twenty-four mice were not sensitized and forty-eight mice were sensitized by intraperitoneal injection of OVA. Of the sensitized mice, twenty-four mice didn't administrate Sabaek-san and twenty-four administrated Sabaek-san. Mice were sensitized on days 1 and 14 by intraperitoneal injection of 20 fig OVA. On days 21, 22 and 23 after the initial sensitization, the mice were challenged for 30 minutes with an aerosol of 1% OVA in saline. Sabaek-san administered 200㎎/㎏ in the tail of the mouse, one time per day, for 7 days, beginning 14 days after first sensitization. Bronchoalveolar lavage was performed 72 hours after the last challenge, and total cell numbers in the BAL fluid were count. Also, level of MMP-9 in the BAL fluid were measured by Enzyme immunoassays and Western blot analysis. Enzyme immunoassay revealed that MMP-9 levels in the BAL fluids significantly increased 72 h after OVA inhalation compared with levels in the control group. After administration of the Sabaek-san, the levels of the MMP-9 in BAL fluids 72 h after OVA inhalation reduced dramatically. Western blot analysis revealed that MMP-9 levels increased in the all mice which were challenge with OVA without administered Sabaek-san compared the normal mouse. However, in the groups of the administered Sabaek-san, the MMP-9 level markedly decreased. Sabaek-san might be effect the treatment of the bronchial asthma as a inhibition of the MMP-9.

  • 연구배경: 기관지천식은 호산구성 기도내 염증반응을 특징으로 하는데 호산구의 침윤에 관여하는 cytokine으로 T 림프구에서 분비되는 IL-3, IL-5, GM-CSF 등이 잘 알려져 있다. 한편 IL-10은 항염증성 cytokine으로 이러한 cytokine 분비를 억제할뿐만아니라, 호산구에 대해서는 직접적으로 자사(apoptosis)를 유도하고 조직내 첨착을 억제하는 기능을 갖고 있다. 본 연구에서는 기관지천식 환자에서의 기관지폐포세척액과 말초 혈액단핵세포에서 분비되는 IL-10을 정상대조군과 비교하고 기도내 염증반응정도와의 연관성을 분석하여 기관지천식에서의 IL-10 역할을 알아보고자 하였다. 방 법: 기관지천식환자 23명, 정상대조군 11명을 대상으로 기관지폐포세척액내와 말초혈액단핵구에서 분비되는 IL-10을 ELISA 방법으로 측정하고, 기도의 염증반응정도는 기관지세포세척액내 총세포수 및 호산구분율과 기관지 생검조직내 호산구 침윤정도, methacholine 기관지유발 검사에서 $PC_{20}$값으로 평가하였다. 결 과: 기관지폐포세척액내 IL-10과 말초혈액단핵구에서 분비되는 IL-10은 기관지천식 환자군과 정상대조군 사이에 통계적으로 유의한 차이는 없었다. 기관지천식환자군에서 기관지폐포세척액내 IL-10은 기관지폐포세척액내 호산구분율 및 기관지 조직내 침윤된 호산구수와는 유의한 역상관관계를 보였고, 메타콜린에 대한 PC20에 따른 차이는 없었다. 말초혈액단핵구에서 분비되는 IL-10은 기관지폐포세척액내 IL-10과 상관 관계가 없었으며, 말초혈액내 호산구수나 eosinophilic cationic protein과도 유의한 상관관계가 없었다. 결 론: 기관지천식 환자군의 기관지폐포세척액내 IL-10은 기관지폐포세척액이나 기관지 조직내 호산구 침윤과 역상관관계를 보였지만, 정상대조군과 비교해서 IL-10 감소가 관찰되지 않았기 때문에 기관지천식에서는 항염증 효과가 있는 IL-10이 중요하게 작용하지 않을 것으로 생각된다.

  • With the recent increase in asthma, asthma has become recognized as one of the diseases. The perception that bronchial asthma is a chronic disease and requires treatment has been strengthened. In addition, asthma is recognized as a dangerous disease due to environmental changes and efforts are made to minimize these risks. However, the environmental impact on asthma is hardly a factor that individuals in asthmatic patients can cope with. Therefore, this study was conducted to see if the asthma disease could be replaced by the individual efforts of asthma patients. In particular, since the management of asthma is important during adolescence, we conducted research on asthma in teenagers. Utilizing support vector machines, artificial neural networks and deep learning techniques that have recently drawn attention, we propose models to predict the asthma of teenagers. The study also provides guidelines to avoid factors that can cause asthma in teenagers.

  • This study aimed to discover functional materials derived from resources, which can improve the troublesome symptoms of a bronchus by improving bronchial hyperresponsiveness as air pollution in Korea caused by fine dust and yellow dust is getting worse. Of natural resources grown naturally in Korea, Chrysanthemum morifolium(CM), and Scutellaria baicalensis(SB) have been used as a safe raw material for drinking or medicine for a long time, and it has been found that a combination of CS73 can improve bronchial health function in experimental animal models. Analysis of serum of animal models with asthma induced by ovalbumin (chicken egg albumin) and analysis of cytokine production in BALF (Bronchoalveolar lavage fluid) showed that inflammatory indices IL-1β, IL-4, IL-5, IL-6, IL-10, IL-13, IL-17A, IL-17F, and IL-17E were significantly reduced and that respective production of IL-2 and IFN-γ was significantly increased in the group taking extracts from CS73 when compared with the control group. These results suggested that the combination of CS73 could be used as a natural treatment for asthma. In addition, in the animal models that the combination of CS73 significantly decreased the respective production of IgE, histamine and TSLP when compared with the control group. In experimental models, the ratio of Chrysanthemum morifolium to Scutellaria baicalensis of 7 : 3 had more excellent effect than other combined experimental groups, which suggests that the above combination can be developed as a natural treatment for asthma and is valuable as a pharmaceutical composition with an effect of improving bronchial health, capable of contributing to the public health threatened by fine dust.
