Pyunkang-hwan (Pyunkang-tang) extract (PGT) is a traditional folk medicine for controlling diverse pulmonary diseases including bronchitis, tonsiltis and pneumonitis. We investigated whether PGT significantly affects secretion, production and gene expression of airway mucin using in vivo and in vitro experimental models reflecting the hypersecretion and/or hyperproduction of mucus observed in inflammatory pulmonary diseases. For in vivo experiment, effect of PGT was checked on hypersecretion of pulmonary mucin in sulfur dioxide-induced bronchitis in rats. For in vitro experiment, confluent NCI-H292 cells were pretreated with PGT for 30 min and then stimulated with EGF (epidermal growth factor), PMA (phorbol 12-myristate 13-acetate) or TNF-${\alpha}$ (tumor necrosis factor-${\alpha}$) for 24 h. The MUC5AC mucin gene expression and mucin protein production were measured by RT-PCR and ELISA. The results were as follows: (1) PGT inhibited the expression of MUC5AC mucin gene induced by EGF, PMA or TNF-${\alpha}$ from NCI-H292 cells, respectively; (2) PGT also inhibited the production of MUC5AC mucin protein induced by the same inducers from NCI-H292 cells, respectively; (3) PGT inhibited secretion of mucin in sulfur dioxide-induced bronchitis rat model. This result suggests that PGT can regulate secretion, production and gene expression of airway mucin.

A patient,58 years of age, with suspected 0/l pneumoconiosis since 1993, complained of a dry cough and exertioning dyspnea for 6 months. He had worked in an asbestos company for more than 20 years from 1974. He was subsequently diagnosed with an interstitial lung disease during an annual special health check-up for asbestos workers. h chest X-ray showed an interstitial lung disease and high-resolution computed tomography (HRCT) showed a round opaque asbestosis with chronic hypersensitivity pneumonitis. A pulmonary function test indicated that the patient had a mild restrictive lung disease with FEV1 1.67 litters and 82% FEVl/FVC. The bronchoalveloar larvage fluid included many asbestos bodies, indicating previous exposure to asbestos. Transmission electron microscopy (TEM) using an energy dispersive X-ray analyzer (EDX) revealed many asbestos bodies consisting of mainly crocidolite fibers (6,071$\times$$10^6$fibers/g of dry lung). The patient had an unusually high asbestos content of 6,112$\times$$10^6$ asbestos fibers/9 of dry lung.

Benign endobronchial tumors are rare diseases with an incidenced of between 1 and 5% of all Jung tumors. An endobronchial fibroepithelial polyp is an extremely rare form of benign bronchial tumor. Clinically, an endobronchial fibroepithelial polyp causes an airway obstruction and obstructive pneumonitis as does other endobronchial tumors. Therefore, it is important to differentiate an endobronchial fibroepithelial polyp pathologically from other benign endobronchial tumors and bronchogenic carcinomas. Here, we report a case of an endobronchial fibroepithelial polyp, in a 25-year-old man who had suffered from chest discomfort upon deep breathing with a brief review of the relevant literature.

A 43-year-old woman with breast cancer who was on neoadjuvant chemotherapy presented with cough, sputum and mild fever. High-resolution computed tomography showed diffuse ground glass opacities in bilateral lungs and subpleural patchy consolidations. Initially, she was thought to have pneumonia or interstitial lung diseases such as drug-induced pneumonitis and treated with antibiotics and steroids. She subsequently got breast cancer surgery because of disease progression, and concurrent thoracoscopic lung biopsy revealed metastatic carcinoma of the lung from breast cancer. The diagnosis of suspected interstitial lung disease can be made without lung biopsy, but malignancy should always be considered and lung biopsy should be performed in the absence of a definitive clinical diagnosis.

Sj$\ddot{o}$gren's syndrome(SS) is a chronic inflammatory disorder characterized by lymphocytic infiltration of lacrimal and sailvary glands, which results in dry eyes and dry mouth. SS may exist as a primary condition or as a secondary condition in association with connective tissue disease such as rheumatoid arthritis, systemic lupus erythematosus, or progressive systemic sclerosis. We experienced a patient with primary SS who developed multiple bullae, nodular type of pulmonary amyloidosis and lymphocytic interstitial peumonitis. We believe this to be the first reported case of SS acompanied by these three types pulmonary manifestations at the same time.

Isolated(H-type) tracheoesophageal fistula without esophageal atresia occurs in approximately 4% of esophageal anomalies, and represents the least form of abnormal laryngotracheo-esophageal communication. Its symptoms such as coughing and choking The during the feeding, abdominal distension and recurrent pneumonitis usually start from birth. Diagnosis is made between 4 days to 4 years using the contrast esophagography and/or tracheoscopy. In case of diagnostic delay the postoperative mortality is not negligible and the most common cause of mortality is respitatory problems(infection, respiratory distress). So early diagnosis is essential in the newborn period with high index of suspicion. We report a case of H-type TEF in which operative repair was successful with references to recent literature.

Valproic acid is one of the most common antiepileptic drugs used for the treatment of several seizure disorders. A 20-year-old man presented with a sudden decline of consciousness. He had a neurosurgery operation for intracranial and intraventricular hemorrhage. Following surgery, antiepileptic medication was administered to the patient in order to control his seizure events. On valproic acid treatment, he began to complain of fever and dyspnea. His symptoms persisted despite receiving empirical antibiotic treatment. All diagnostic tests for infectious causes were negative. A high-resolution computed tomography scan of the chest revealed predominantly dependent consolidation and ground-glass opacities in both lower lobes. The primary differential was drug associated with interstitial lung disease. Therefore, we discontinued valproic acid treatment and began methylprednisolone treatment. His symptoms and radiologic findings had significantly improved after receiving steroid therapy. We propose that clinicians should be made aware of the potential for valproic acid to induce lung injury.

목적 : 절제 불가능한 제 3기 비소세포성 폐암에서 다분할 방사선 치료와 MVP 복합 항암요법의 동시 치료에 의한 종양관해율, 급성부작용, 생존기간에 미치는 효과를 알아보기 위하여 1993년 8월부터 전향성 연구(Prospective study)를 시작하였다. 방법: 본 연구는 제 III기의 비소세포성 폐암중 절제가 불가능한 환자를 대상으로 하여 다분할 방사선치료(120 cGy/fx, BID)를 6,480 cGy 시행하며 동시에 방사선치료 제1일과 28일에 2회의 MVP (Mitomycin C $6mg/m^2,$ Vinblastine $6mg/m^2,$ Cisplatin $60mg/m^2$) 복합 항암 요법을 시행하였다. 1994년 11월까지 등록된 62명의 환자에 대한 분석을 시행하였다. 병기는 IIIa 환자가 6명이고 나머지 56명은 IIIb 환자였으며 이중 흉막액이 있었던 환자는 11명, 쇄골상 임파선 전이가 있었던 환자는 10명으로 대부분의 환자가 IIIb 중에서도 진행된 환자였다. 조직학적 유형은 편평 상피암이 41명으로 $66\%$ 선암도 11명으로 $18\%$를 차지하였다. 결과: 52명의 환자중 끝까지 치료를 마친 환자는 48명으로 이 study의 compliance는 $77\%$이었다. 48명의 환자중 2명은 치료중 치료와 관계된 백혈구 감소로 인한 폐렴으로 사망하였다. 치료의 효과를 판정할 수 있었던 46명의 환자중 완전 관해(CR)는 10명으로 $22\%$의 높은 완전 관해율을 보였다. 부분 관해(PR)는 24명 $(52\%)$ 으로 다분할 방사선 치료와 동시 병행 MVP 항암요법에 의한 부분관해 이상의 관해율은 $74\%$ 이었다. 급성부작용 판정이 가능했던 46명중 가장 빈도가 높은 금성 부작용은 백혈구 감소로 1차 항암요법후 10명이 Grade 3, 4명이 Grade 4의 백혈구 감소를 보였으며 2차 항암요법에는 11명이 Grade 3, 9명이 Grade 4의 백혈구 감소를 보여 치료기간이 3일에서 5일 정도 지연되는 결과를 나타냈고 이중 2명은 폐렴으로 인한 패혈증으로 사망하였다. 치료중 체중감소를 보인 환자는 26명 $(54\%)$ 이었으며 이중 9명에서는 치료전에 비해 $10\%$ 이상의 체중감소를 보였다. 치료 1개월후 찍은 CT상 6명에서는 Grade 1의 방사선 폐렴이 관찰되었고 3명에서는 Grade 2로 Steroid 치료후 호전되었다. 결론: 이상의 결과 다분할 방사선 치료와 MVP 항암요법의 동시 치료가 이전의 항암요법후 다분할 방사선 치료하는 Sequential 방법에 비하여 높은 관해율을 보이고 특히 $22\%$의 높은 완전 관해율이 관찰되어 이 연구를 계속 진행함으로써 더 좋은 결과를 얻을 것으로 생각되며 급성 부작용에 대하여는 입원을 통한 Nutrition support와 G-CSF 등을 이용하여 백혈구 감소를 막을 수 있을 것으로 생각된다.
