  • Equisetum hyemale Linne. (EH) (Equisetaceae) has been used for the treatment of eye and skin disease, chronic eczema, pneumoconiosis and asthma in Korea and China. Human leukemic mast cells are widely distributed in the connective tissues of mammals and other vertebrates. Phorbol 12-myristrate 13-acetate (PMA) and calcium ionophore A23187 stimulated Human leukaemic mast cell line-1 (HMC-1) can produce a variety of inflammatory mediators and several pro-inflammatory and chemotactic cytokines such as TNF-$\alpha$, IL-6 and IL-8. Since TNF-$\alpha$, IL-6 and IL-8 are major factors during the inflammatory process, we studied the effects of EH on TNF-$\alpha$, IL-6 and IL-8 release in HMC-1 stimulated with PMA and A23187. The result of this study indicate that EH inhibits TNF-$\alpha$, IL-6 and IL-8 in activated HMC-1 cells via $I{\kappa}B$/Nuclear factor-${\kappa}B$ pathway. Therefore, EH might contribute significantly to the prevention or treatment of mast-cell mediated inflammatory diseases and EH has potential use in the therapy of chronic allergic inflammation.

  • The aim of this study was to investigate the effects of several herbal prescriptions in patients with allergy or atopic disease, such as atopic dermatitis, asthma and allergy rhinitis and others, on the blood immunological parameters and to verify the safety of long-term use of herbal medicine. Eighty one patients with allergy or atopy disease who taken herbal medicine at least for 2 months were compared with patients who taken same medicine with no allergy & atopy disease (n=14) and normal healthy subjects (n=22). According to the comparison of immunological parameters change, the data showed that herbal medicine decreased IgE (P=0.003), Eosinophil ratio (P<0.001) and count (P<0.001) of White Blood Cell (WBC) and did not affect to the liver cell enzymes in blood. This results indicated that herbal medicine decreased immune hypersensitivity and improved chronic inflammation related to blood immunological parameters of allergy or atopy diseases. In addition, herbal medicine seemed to be safe to the liver function for long-term use.

  • To evaluate antiallergic effect of Brassica rapa Metzg (BR, Family Cruciferae), which is widely used as a food source, its anti-asthmic effect was investigated. BR reduced IgE level in the blood of ovalbumin (OVA)-induced asthmic mice. BR also inhibited IgE and ploinflammatory cytokine IL-6 productions in trachea of OVA-induced mice, but did not inhibit IL-4 production. BR did not inhibit mRNA expression of proinflammatory cytokines IL-6 and IL-4 in IgE-induced RBL-2H3 cells. BR and its isolated components 10-undecenoic acid 2-methoxy methyl ester and galactosyl diglyceride potently inhibited the NO production of RAW264.7cells induced by lipopolysaccharide. These findings suggest that the anti-asthmic effect of BR may be due to the inhibition of the biosynthesis of proinflarnmatory cytokine IL-6 in macrophage and BR can improve IgE-induced allergic disease asthma.

  • Epidemiological studies have shown that exposure to tobacco smoke causing irritation and inflammation in the airways tends to reduce serum periostin concentrations in adults. We now investigate prospective cross-sectional study on 135 Korean students aged 7 years in the first grade who were participating in the Seongnam Atopy Project for Children's Happiness 2016 ($SAP_{2016}$) cohort. To the best of our knowledge, this is the first study to show significant inverse correlations between serum periostin concentration and exposure to xylene and formaldehyde in children. Our findings suggested the need for caution in using the serum periostin level as a marker for allergic diseases, since exposure to volatile organic compounds and formaldehyde may confound the interpretation of these results.

  • 목 적 : 본 연구에서는 현증 천식 환자의 BHR에는 기도 염증이 중요한 요인으로 작용하기 때문에 ${\beta}_2$-아드레날린 수용체 유전자와의 연관성이 나타나지 않지만, 청소년기 천식 관해 상태에서 지속되는 BHR에는 상대적으로 유전적인 영향이 강하기 때문에 ${\beta}_2$-아드레날린 수용체 유전자와의 연관성이 나타날 것이라는 가설을 세우고, 이를 검증해 보고자 하였다. 방 법 : 장기간 천식 관해 상태(최근 2년간 천식 증상이 없고 치료가 필요 없었던 경우)에서 BHR이 지속되는 청소년 202명(천식 관해군), 현증 천식 청소년 182명(현증 천식군), 정상군 200명을 대상으로, 메타콜린 기관지 유발검사와 피부단자시험을 시행하였으며 혈청 총 IgE를 측정하였다. ${\beta}_2$-아드레날린 수용체 유전자의 일배체형 분석을 위해 아미노산 16번과 27번을 포함하고 있는 ${\beta}_2$-아드레날린 수용체 유전자 부위를 polymerase chain reaction(PCR)으로 증폭한 뒤, 16번 유전형은 allele specific PCR, 27번 유전형은 PCR-restriction fragment length polymorphism (RFLP) 방법으로 분석하였다. 결 과 : Gly 동형접합자(homozygote)의 빈도는 정상군에서 14.5%, 현증 천식군에서 18.1%, 천식 관해군에서 24.2%로 증가하는 경향이 관찰되었으며(P=0.01), 현증 천식군과 정상군 사이에서는 차이가 없었지만 천식 관해군과 정상군 사이에서는 유의한 차이가 관찰되었다(P=0.01). Gly16-Gln27 일배체형 빈도는 정상군에서 36.5%, 현증 천식군에서 40.4%, 천식 관해군에서 44.6%로 증가하는 경향이 관찰되었으며(P=0.02), 현증 천식군과 정상군 사이에서는 차이가 없었지만 천식 관해군과 정상군 사이에서는 유의한 차이가 관찰되었다(P=0.02). 천식 관해군에서 Gly16-Gln27 일배체형의 수가 증가함에 따라 $PC_{20}$ 기하 평균값이 유의한 차이를 보임으로써(P=0.02) Gly16-Gln27 일배체형과 $PC_{20}$ 사이의 연관성이 관찰되었으나 현증 천식군에서는 이러한 연관성이 관찰되지 않았다. 결 론 : ${\beta}_2$-아드레날린 수용체 유전자가 BHR을 유발하는 유전자적 배경을 가지면서 천식 질병을 조절하는 역할을 하고 있음을 시사한다.

  • Objectives : In the theory of Korean medicine, Pear has long been considered to protect throat, bronchus and lung. Pear has been believed to remove sputum in Korean people. This study was conducted to investigate the effect of pear ethanol extract (PEE) on asthma induced by ovalbumin in mice. Methods : We investigated the effects of PEE on airway hyperresponsiveness to methacholine, production levels of ovalbumin (OVA) specific total immunoglobulin G (IgG), IgG1, IgG2a and IgE in serum and histopathological changes of lung tissues in asthamtic mice. Results : PEE decreased airway hyperresponsiveness to methacholine significantly compared to non-treated asthmatic mice (P<0.05). Level of OVA specific IgE in serum was lowered by oral administration of PEE effectively (P<0.05). In histopathological observation, administration of PEE reduced infiltration of immune cells into lung tissue. Conclusion : These results suggest that pear has anti-asthmaitc action and related mechanims are involved in anti-inflammatory action such as reducing level of OVA specific IgE and immune cell infiltration.

  • Objectives : Asthma is considered an inflammation disease characterized by airway hyperresponsiveness and pulmonary eosinophilia. Chungsang boha-tang is a herbal medication which has been frequently used in traditional therapeutic agents for asthma. We aimed to observe the clinical effects of Chungsangboha-tang on blood eosinophil, serum IgE, AST, ALT and pulmonary function in asthmatic outpatients. Methods : The subjects consisted of 66 asthmatic patients who had been treated with Chungsangboha-tang among all the asthmatic patients who visited the 5th Internal Medicine of the Oriental Medicine Hospital of Kyung Hee University from November,2004 to November,2009. We observed blood eosinophil, serum IgE, AST, ALT levels and pulmonary function test results as well as medical records of patients to evaluate the effects. Results : Pulmonary function significantly improved after 8 weeks of treatment, and blood eosinophil and serum IgE level significantly decreased after 8 weeks of treatment. AST, ALT levels changed in normal ranges. Chungsangboha-tang was significantly effective on the male patients who had a smoking history and worse initial lab findings. We also observed a significant improvement of pulmonary function and decrease of eosinophil and serum IgE levels in the patient group who had a single treatment of Chungsangboha-tang without steroid therapy. Conclusions : This study shows that Chungsangboha-tang has effects on the improvement of pulmonary function and decrease of eosinophil and serum IgE levels as well as improvement of symptoms. And, 8 weeks of long-term treatment showed no negative effects such as significant increase of AST, ALT levels.
