The cosmetic and stimulating effects of lemon oil have been widely proven in the fields of beauty therapy and psychology therapy. But the lemon oil's proper effects on the anti asthma and the anti inflammation have not rarely been verified. This study was conducted to find out the lemon oil's effects on the anti asthma and anti inflammation in the OVA-induced allergic asthma mice model. OVA-induced allergic asthma mice were divided into 4 groups consisting of normal group, control group, positive control group and experimental group. 0.3% of lemon oil was nebulized to experimental group for 3 weeks on a basis of 3 times per week and 30 min each time. After 6 weeks from the initial experiment, the degree of hyper activeness of respiratory system, the hematological change, the amount of the cytokein in serum, the change of airway organization were evaluated. The results showed that lemon oil controled effectively the hyper activeness of respiratory system and restricted the multiplication of cells in acidophil in terms of statistical significance. It also turned out that lemon oil restricted effectively the infection of airway reaction and the hyper sensitiveness of respiratory system by controlling the creation of histamine(cytokein) and IgE.

호흡기 바이러스 감염은 모든 연령층의 천식에 상당한 영향을 미치는 데 영아에서 RSV는 천명을 야기하고 대부분 일시적이나 재발성 일수도 있다. 어릴 때 바이러스 감염은 면역체계 형성에 영향를 미쳐 알러지와 천식의 위험을 완하할 수있다고 한다. 또한 소아와 성인 천식에서 RV같은 감기 바이러스는 천식의 급성 증상을 유발한다. 호흡기 바이러스 감염에 대한 면역반응이, 기관지로 부터 바이러스 제거 기능외에 기도수축과 호흡기 증상에 관여한다고 한다. 이러한 변화가 일어나는 기전은 호흡기 바이러스가 proinflammatory 사이토카인과 매개체 생성을 유도하는 능력과 연관성이 있는 것 같고 이들이 상하기도 호흡기 증상 및 기도반응 변화에 관여하는 것으로 생각된다. 호흡기 바이러스 감염에 대한 면역반응을 요약하면 바이러스 감염으로 상피세포, 내피세포, 과립백혈구가 활성화되며, 상피세포는 사이토카인, 키모카인, 매개체들을 분비하여 항 면역 반응를 주도하다. 이와 같은 상피세포와 다른 기관지 세포들의 조기 활성화로 내피 세포에 유착분자 표현을 증가시켜 백혈구 동원 증가 및 혈관 투과성을 증가시켜 부종과 분비물을 증가시킨다. 바이러스 또는 바이러스 유발 사이토카인에 의해 활성화된 과립 백혈구, 대식세포, T세포들도 기도염증 증가, 기도폐쇄를 야기하고 기도반응을 증가시킨다. 세포독성 임파구에 의한 바이러스 감염세포의 분해, TGF-$\beta$ IL-10 같은 사이토카인에 의해 부분적으로 염증억제, 기도 remoldeling에 의한 기도구조의 재생등이 바이러스 감염후 기관지 기능의 지속적 변화를 결정한다. 끝으로 천식환자에서 RV 감염의 병인에 관한 기본적 문제는 RV감염이 정상인에서는 경한 증상을 나타내는 데 천식환자에서는 왜 심한 임상증상을 나타내는지 아직 완전히 밝혀지지 않았다. 항 바이러스에 대한 면역반응이 천식환자에서 손상되었는지 또는 천식환자에서 RV감염에 의한 중증의 임상증상은 어떤 다른 세포가 관여하는지? 이들에 대한 답은 기도염증이 천식에서 어떻게 조절되는지 또한 바이러스 감염에 의한 악화된 증상을 어떻게 치료할 것인가에 대한 방향을 제시해줄 것이다.

This study was aimed to evaluate the effects of Cypress oil(CS) on anti-asthmatic activities in a mouse model of allergic asthma. Using an Ovalbumin-induced allergic asthma mouse model, 0.3% of CS was administered to experimental group using a nebulizer for 3 weeks on a basis of 3 times per week and 30min each time. The degree of airway hypersensitivity, the number of eosinophil in white blood cells, the number of immune cells and the change of cytokine in lung tissue were evaluated. The degree of airway hypersensitivity, the number of eosinophil, IL-5 and IL-13 levels in lung tissue, IgE in serum, the number of CCR3, CD3, CD4 cells were significantly decreased in experimental group treated with CS. These results suggested that CS may have a positive effects on Th2 cytokine and eosinophils which are major factors of asthma responses. Therefore CS might be of therapeutic value in treating asthma.

This study was performed to evaluate the antioxidant activities and anti-asthma effects of Morus bark water extracts. Inhibitory effect of Morus bark onto free radical generation was determined by measuring DPPH and hydroxyl radical scavenging activities in vitro. Anti-asthma activities of Morus bark water extracts were assessed by testing their effects on the degranulation of mast cell. For this, $\beta$-hexosaminidase released from a basophilic cell line, RBL-2H3 was used and pro-inflammatory cytokines were measured by ELISA kit. The antioxidant activities of water extracts of Morus bark was 59.2% in the DPPH assay at $2,000\;{\mu}g/mL$ and 78.8% in the hydroxyl radical scavenging assay at $2,000\;{\mu}g/mL$. Our results indicated that Morus bark water extracts effectively inhibited free radical generation. Morus bark water extracts inhibited inflammation-mediating substances such as histamine and $\beta$-hexosaminidase release from RBL-2H3 cells. Cytokine release demonstrated a more effective blockading ability of the Morus bark water extracts to the release of IL-4 and TNF-$\alpha$ compared to control. These results demonstrate that Morus bark may be beneficial in the treatment of allergic inflammatory disease.

The aim of the convergence study is to evaluate anti-asthma effects of white ginseng complex extract(WGCE) on OVA-induced allergic asthma in mice. WGCE was administered at 100 mg/kg and 300 mg/kg to mice, where asthma was induced by OVA. Th2 cytokine including IL-4, IL-5 and IL-13 were measured by Luminex. Also, OVA-IgE and eosinophil were measured by haemocytometer and BALF total cells were measured microscope. Production of IL-4, IL-5, IL-13 and OVA-IgE in serum was decreased, respectively, in comparison with control. The eosinophil in whole blood decreased significantly. In addition, WGCE groups showed a decrease in the BALF total cells. These results demonstrated that WGCE decreases the Th2 cytokine and asthma factors. Therefore, we strongly suggest that WGCE could be effectively used as a therapeutic drug based on its anti asthma factors.

Inflammation through the respiratory tract is a crucial event in immune disorders, including asthma, and atopic rhinitis. To investigate whether an aqueous extract of Angelica archangelica L. (AaL) has a beneficial influence in terms of anti-asthmatic activity, its effects on an ovalbumin-induced asthmatic model were examined. Mice sensitized to ovalbumin were orally administered the AaL extract, and their lungs examined by Haematoxylin-Eosin staining to determine IL-4/13 cytokine expression. The AaL extract exerted strong anti-asthmatic effects by regulating each level in the $CD4^+$ cell number, IL-4/13, and other target markers in the lungs. Together, these results collectively indicate that the aqueous AaL extract ameliorates asthmatic symptoms effectively in a mouse ovalbumin-challenge model.

소아천식은 기도의 만성 염증 및 과민반응을 특징으로 나타내고 있어 염증을 일으키거나 알레르기 반응을 일으키는 물질로부터 차단하는 방법이 효과적임을 현대의학에서 이미 밝히고 있다. 한의학에서는 천증(喘證)에 본디 뿌리 깊은 근원(천유숙근(喘有夙根))이 있다고 간주하여 허약한 체질은 내적인 요인이고, 풍한침습(風寒侵襲)은 유발요인이며, 담음복폐(痰飮伏肺)와 신기휴허(腎氣虧虛)는 재발의 근본이라고 하였다. 본 연구에서는 소아 천식에 구마황(灸麻黃), 은행(銀杏), 건강(乾薑), 오미자(五味子), 백전(白前), 구백부(灸百部), 소자(蘇子) 등을 사용하였고, 경우에 따라 황기(黃?) 혹은 선령비(仙靈脾)를 추가하여 正氣(正氣)를 강화시키는 목적으로 사용하였다. 약리학적 연구에 따르면 마황과 건강, 오미자 등은 모두 기도의 염증세포 침윤(浸潤)를 억제하고 항알레르기 효과가 있으며, 건강과 오미자는 또한 히스타민에 대한 길항효과(拮抗效果)도 있는 것으로 알려져 있다. 은행 추출물은 혈소판 활성화 수용체에 대한 길항작용을 갖고 있으므로 이러한 물질들로 인한 기관지의 경련을 방지하여 천식증상을 왕화시킨다. 구백부(灸百部)는 지해(止咳)효과가 뛰어나다. 소아천식에 대한 치료는 표본동치(標本同治)의 원칙을 지키며, 증상이 완화된 단계에서도 중약 투여를 1-2개월 지속시키는 것이 중요하다. 소아에게 있어서 천식증상이 완화된 후 어혈(瘀血) 상태가 성인에 비해 심하지는 않지만, "구병필어(久病必瘀)"의 결과에 유의할 필요가 있다. 천식이 장기간 지속되면 필히 혈액순환 장애가 수반되므로 천궁(川芎)이나 단삼(丹蔘) 등의 활혈제(活血劑)를 가미하여 사용하면 효과를 높일 수 있다. 결론적으로 소아의 천식은 항염증, 평천(平喘), 화담(火痰), 지해(止咳)와 더불어 보신익기화어(補腎益氣化瘀)의 약물을 병행하여 사용하는 것이 바람직하며, 단순한 중약 투여는 일부 양약에 의한 소아성장에 미치는 영향을 피할 수 있어 더 많은 임상연구가 이어져야 한다.

Codonopsis lanceolata (Campanulaceae) has been widely used in traditional medicine and is considered to have medicinal properties to treat diseases and symptoms such as bronchitis, coughs, spasm, edema, hepatitis, colitis, and lung injury. In order to investigate whether native Codonopsis lanceolata extract alleviates ashmatic symptoms in vivo, we first carried out various antioxidant activities by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, ferric reducing antioxidant power (FRAP), and cupric reducing antioxidant capacity (CUPRAC) assays. The antioxidant activities were increased by adding Codonopsis lanceolata extract in a concentration-dependent manner which compared to ascorbic acid as a positive control. Histological studies using an ovalbumin-induced animal model exhibited potent anti-inflammatory potential by decreasing immuno-responsive cells in the lung by the extract by confirming H&E and PAS staining. It is revelaed that further immunihistochemical analysis showed anti-ashmatic capabilities by assessing histamine, IL-31, and MMP-9 expressions. The level of IL-13 expression in Codonopsis lanceolata extract-treated group was decreased upto 73.7% compared to control, whereas that of total cells and eosinophil counting in Codonopsis lanceolata extract-treated group was diminished to 73.5% and 80.9%, respectively. These results collectively indicate that the C. lanceolata extract ameliorates asthmatic symptoms effectively in an ovalbumin-challenged mice model, in that the extract can be used for the development of an anti-asthmatic food ingredient.
