  • Objectives : Sojadodamgangki-tang and its main components are traditional korean medicinal methods for treatment of cough, sputum and dyspnea. Using a respiratory inflammatory model, we intend to reveal the anti-inflammatory effect and its immune mechanism of Sojadodamgangki-tang. Methods : We used a papain-induced respiratory inflammatory mouse model. 8-week-old female BALB/C mice were divided into 3 groups as follows: the following groups: saline control group, papain treated group (vehicle), papain and Sojadodamgangki-tang(200 mg/kg) treated group (n=4). To evaluate the anti-inflammatory effect of Sojadodamgangki-tang extracts, inflammatory cell infiltration was measured in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). In addition, the effects of Sojadodamgangki-tang extracts on Th2 cell population in lung were determined by using flow cytometry. Results : Sojadodamgangki-tang extracts administration reduced inflammatory cell infiltration in BALF and NALF, especially of eosinophils. Furthermore, total immunogloblin (Ig)-E levels was reduced in BALF and serum by drug administration. Interestingly, Sojadodamgangki-tang extracts treatment also decreased the Th2 cell (CD4+GATA3+) population in lung. Conclusions : Our findings indicate Sojadodamgangki-tang extracts have anti-inflammatory effects by mediating Th2 cell and B cell activation.

  • 목 적 : 폐표면활성제의 비활성화는 태변 흡인 증후군의 중요한 기전으로 알려져 있다. 저자들은 중증 태변 흡인 증후군에서 인공 폐표면활성제 세정요법의 효과를 연구하고자 하였다. 방 법 : 2005년 3월부터 2007년 8월까지 연세대학교 의과대학 영동세브란스병원 신생아 중환자실에 중증 태변 흡인 증후군으로 입원한 만삭아 15명 중 본 기관에서 인공 폐표면활성제 세정요법을 시행한 이후인 2006년 12월부터 2007년 8월까지 입원하여 태변 흡인 증후군을 진단 받고 oxygen index가 15 이상 혹은 평균 기도압이 $12cmH_2O$ 이상인 환아 7명을 대상으로 20 mL/kg 의 희석 된 인공 폐표면활성제($Newfactan^{(R)}$)로 세정요법을 시행하였다. 동일한 선별기준에 따라 2005년 3월부터 2006년 11월까지 입원하여 보존적 치료를 시행한 환아를 후향적으로 조사하여 8명의 대조군으로 정하였다. 결 과 : 세정요법 군은 특이 이상 반응 없이 안전하게 세정요법을 시행받았으며, 치료 6시간 후부터 방사선학적인 호전을 보였다. 세정요법 시행 6시간 후 oxygen index, ventilation index는 대조군에 비해 유의하게 감소하였으며, 평균 호흡기 사용시간, 평균 재원기간에 있어 대조군에 비해 유의한 감소를 보였다. 두 군간에 합병증이나 치사율에 차이는 보이지 않았다. 결 론 : 본 연구에서 희석된 폐표면활성제로 세정요법을 시행한 환아들이 조기에 산소화가 향상되고 기계환기의 기간을 줄일 수 있음이 확인되어 중증 태변 흡인 증후군의 치료로서 폐 표면활성제 세정 요법은 안전하고 효과적으로 독성물질을 제거할 수 있으며 폐표면활성제가 작용할 수 있는 방법으로 여겨진다. 향후 대규모의 다기관 임상연구가 필요하리라 생각된다.

  • This study was carried out to investigate if nitric oxide synthase (NOS) inhibitors modulate airway inflammation induced by diesel exhaust particles (DEP). N$\^$G/-nitro-L-arginine methyl ester (L-NAME), a potent constitutive NOS (cNOS) inhibitor, and aminoguanidine (AG), a selective inducible NOS (iNOS) inhibitor, were administered to mice in their drinking water for 7 weeks. Airway inflammation was elicited by the repeated intratracheal administration of DEP. The results showed that macrophages, inflammatory eosinophils and neutrophils in bronchoalveolar lavage (BAL) fluids by intratracheal DEP instillation were significantly suppressed in the mice treated with two NOS inhibitors toghther with DEP. The suppression of these cells was more effective in AG treated groups than in L -NAME treated groups. NOS inhibitor treatment also reduced interleukin -5 (IL-5 in the BAL fluids and lung homogenates. Additionally, it was found that eosinophil peroxidase (EPO) activity in the BAL fluids was also decreased by NOS inhibitor treatment. These results suggest that nitric oxide (NO) is produced in airway inflammation by repeated DEP instillation, and that iNOS inhibition as well as cNOS inhibition can play a modulating role in this airway inflammation by DEP.

  • The objective of this study was to investigate the effect of crude ginseng total saponins (CGS) against airway inflammation (AI) and airway hyperresponsiveness (AH) induced by diesel exhaust particles (DEP) in mice. AI and AH were induced by the intratracheal instillation with 0.1 $mg/m{\ell}$ of DEP suspension once a week for 10 weeks combined with ovalbumin (OVA) sensitization. Mice were also treated orally with 75 $mg/m{\ell}$ of CGS, 5 days a week for 10 weeks. Oral CGS treatment decreased in the level of serum immunoglobulin (IgE) and histamine increased by DEP and OVA, and declined respiratory resistance. It also dropped an enhanced infiltration of eosinophils in the bronchoalveolar lavage fluid (BALF) of mice, and an increased 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 CGS may alleviate allergen-related AI and AH in mice and may play an important role in the modulation of asthmatic inflammation.

  • A 61-year-old woman came to the hospital with dyspnea and pleural effusion on chest radiography. She underwent repeated thoracentesis, transbronchial lung biopsy, bronchoalveolar lavage, and thoracoscopic pleural biopsy with talc pleurodesis, but diagnosis of her was uncertain. Positron emission tomography showed multiple lymphadenopathies, so she underwent endobronchial ultrasound-guided transbronchial needle aspiration of mediastinal lymph nodes. Here, we report a case of malignant pleural mesothelioma that was eventually diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration. This is an unusual and first case in Korea.

  • In this study, we isolated ginseng crude saponin (GCS) from Korean red ginseng (KRG) and determined the ginsenoside content in it to investigate the physiological and pathological effects of GCS on acute pulmonary inflammation induced by intratracheal instillation of cigarette smoke condensates (CSC) and lipopolysaccharide (LPS) solution in BALB/c mice. GCS was orally administered at doses of 10 mg/kg and 25 mg/kg for 3 weeks. The recovery rate of GCS from KRG was 6.5 % and total ginsenosides from GCS was 1.13 %, and the content of Rb1 was the highest among them. Total inflammatory cells in the lung homogenates and bronchoalveolar lavage fluid (BALF) increased following intratracheal administration of CSC and LPS. However, GCS administration impaired this increase. Furthermore, it inhibited the increase in leukocytes in the blood, considerably decreased neutrophils in BALF, and declined infiltration of inflammatory cells and deposition of collagen in the tracheal and alveolar tissue. In this study, GCS was found to have a protective effect against acute pulmonary inflammation and it may be beneficial in preventing various respiratory diseases.

  • Objective : The application of Sam So Eum (蔘蘇飮, SSE) as a herbal medicine to treat asthma in mice has been studied and the mechanism of cytokine production in asthmatic mice was discussed. Recently, SSE was known to have anti-allergic activity. However, its therapeutic mechanisms are unclear. Methods : So, we investigated the effects of SSE on levels of several cytokines in bronchoalveolar lavage fluid (BALF) using flow cytometric analysis in allergen-induced asthma. Results : In this experiment, SSE decreased levels of IL-la, IL-17 and GM-CSF respectively. Contrary, SSE restored level of IFN-g toward naive level in BALF. Conclusion : In conclusion, we demonstrate that SSE is useful to treat asthma and it's therapeutic mechanisms are involved in Thl skewing reaction.

  • Recently, a novel influenza A (H1N1) has been recognized as the cause of a worldwide respiratory infection outbreak. Although the symptoms of a novel influenza A (H1N1) are usually mild, the disease can cause severe illness and death. A complication of novel influenza A (H1N1) is pneumomediastinum, a rarely reported condition. We report a case of influenza A (H1N1) complicating pneumomediastinum with subcutaneous emphysema, which had initially presented with blood tinged sputum and chest pain. In addition, we demonstrate bronchoalveolar lavage in influenza A (H1N1).

  • Acute eosinophilic pneumonia (AEP) is a disease characterized by an acute febrile onset, eosinophilia in bronchoalveolar lavage fluid, and a dramatic response to corticosteroids. Although many studies have reported a close relationship between direct cigarette smoking and AEP, few studies have identified an association between passive smoking and AEP. Here, we report a case of AEP in a 19-year-old female with cough, fever, and dyspnea after 4 weeks of intense exposure to secondhand smoke for 6 to 8 hours a day in an enclosed area.
