  • Descurainia sophia seeds methanol extract showed significant anti-influenza activity and we tried to isolate anti-influenza compounds from the D. sophia extract. D. sophia seeds were extracted with 80% methanol and fractionated with n-hexane, ethyl acetate, CHCl3 and n-butanol. The anti-influenza activity of each fraction was assessed using sulforhodamine B (SRB) method in A549 cells, human-derived lung cancer cells. The ethyl acetate and CHCl3 fractions showed the most potent anti-influenza activity. Seven compounds were isolated from CHCl3 fraction and identified 1-decanol (1), 2-(3,4-dihydroxy-2-methylenebutoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (2), daucosterol (3), isorhamnetin (4), quercetin (5), sinapic acid (6), and helveticoside (7) by spectroscopic data such as UV, IR, 1H-NMR, 13C-NMR and mass spectroscopy. Anti-influenza activities of isolated compounds were evaluated using SRB method in A549 cells. Compounds 3, 4 and 7 had significant anti-influenza activity in a dose-dependent manner.

  • Background: Actinomycotic infection is uncommon and primary actinomycosis of the lung and chest wall has been less frequently reported. This disease may present as chronic debilitating illness with radiologic manifestation simulating lung tumor, pulmonary infiltrating lesion, or chronic suppuration. Diagnosis of choice was not definded yet and role of bronchoscopy on diagnosis was not described yet. Methods: From 1989 to 1998, we experienced 17 cases of thoracic actinomycosis. We have reviewed the case notes of 17 patients with thoracic actinomycosis. The mean age at presentation was $53{\pm}13$ years, 11 were male. Results: Cough, hemoptysis, sputum production, chest pain and weight loss were the commonest symptoms. The mean delay between presentation and diagnosis was $6.6{\pm}7.8$ months. There were six patients who presented with a clinical picture of a suppurative lesion and eleven patients were suspected of having primary lung tumor initially. In no cases was made an accurate diagnosis at the time of hospital admission. Associated diseases were emphysema (1 case), bronchiectasis (2 cases) and tuberculosis (2 cases). Bronchoscopic findings were mucosal swelling and stenosis(n=4), mucosal swelling, stenosis and necrotic covering (n=2), mass (n=3), mass and necrotic covering (n=1) and normal(n=6). Radiologic findings were mass lesion(n=8), pneumonitis(n=3), atelectasis(n=3), pleural effusion(n=2), and normal(n=3). Final diagnosis was based on percutaneous needle aspiration and biopsy (n=3), bronchoscopic biopsy specimens (n=9), mediastinoscopic biopsy (n=1) and histologic examination of resected tissue in the remaining patients(n=4) who received surgical excision. Among 17 patients, 13 were treated medically and the other 4 received surgical intervention followed by antibiotic treatment. Regarding the surgically treated patients, suspected malignancy is the most common indication for operation. However. both medically and surgically treated patients achieved good clinical results. Conclusion: Thoracic actinomycosis is rare. but should still be considered in the differential diagnosis of a chrinic, localized pulmonary lesion. Thoracic actinomycosis may co-exist with pulmonary tuberculosis or lung cancer. If the lesion is located in the central of the lung. the bronchoscopy is recommanded for the diagnosis.

  • Herein, we report a case of tumorous endobronchial tuberculosis with successful recovery of atelectasis without any significant bronchial stricture, after repeated expectorations of nodular tissues. A 24-year-old male patient was presented with persistent cough. The patient was diagnosed to be suffering from tuberculous lymphadenitis on right axillar and mediastinum of lung, and was subsequently treated with antituberculosis agents. After two months, clinical deteriorations and atelectasis were observed on right upper lobe of lung. Multiple endobronchial tumorous lesions, which obstructed the right main bronchus, were revealed on bronchoscopy, and based on the endobronchial biopsy findings we confirmed that the patient was suffering from endobronchial tuberculosis. We decided to administer antituberculosis agents without any additional procedure. After few weeks, the patient spontaneously expectorated nodular tissues with vigorous coughing. Later on, the symptoms and atelectasis disappeared and the patient was completely recovered. This case shows that in patients suffering from tumorous endobronchial tuberculosis, endobronchial mass can be expectorated spontaneously without sequelae of significant bronchial stenosis.

  • Humans are exposed to toxic element arsenic (As) from air, food and water The current study was performed to investigate the levels of arsenic in the internal organs (liver, kidney cortex, lung, cerebrum. abdominal muscle and abdominal skin) and to find out correlation with age and interrelationship between tissues in Korean human bodies who had lived in Seoul or Gyeonggi Province and Honam district. The tissues from 43 Korean cadavers were digested with microwave digestion system and arsenic was determined by inductively coupled plasma mass spectrometer (ICP-MS). The mean recovery percentages of arsenic In liver were about 80% and artenic concentrations in human tissues were almost uniform. The mean level of arsenic in internal tissues were at follow ; liver 44.556${\pm}$25.199 ppb, kidney cortex 42.652${\pm}$22.082 pub, lung 31.020 ${\pm}$ 17.504 ppb. cerebrum 35.703 ${\pm}$22.191 ppb, muscle 43.413${\pm}$26.619 ppb and skin 42.106${\pm}$25.8,11 ppb. No significant difference was found in the levels of arsenic between sexes. Meanwhile significant differences between districts where they had lived were found in all tissues tested. The levels of arsenic in the tissues of cadavers who had lived in Seoul Gyeonggi Province were higher than those of Honam district. In addition a positive correlation between As concentration and age was observed only in the cerebrum (p < 0.05). A significantly high correlations between tissues were observed in all tissues tested. This result also shows that the distribution of arsenic is uniform in internal tissues.

  • 1. Objectives: This study is to investigate the association of Sasang Constitution and chronic obstructive pulmonary disease(COPD). 2. Methods: One thousand five hundred forty five persons, more than 40 years old, participated in the community based cohort in Wonju City and Pyeongchang City of South Korea from October 29th in 2007 to February 26th in 2008. The diagnosis of COPD was confirmed by spirometry and based on the diagnostic criteria developed by GOLD (Global Initiative for Chronic Obstructive Lung Disease) standard. Relating items like height, weight, BMI(Body Mass Index), martial status, income, drinking, smoking and education were checked using questionnaires and Sasang Constitution was diagnosed by a specialist using PSSC(Phonetic System for Sasang Constitution), facial photos and check-up lists. 3. Results: There were 88 persons(5.7%) who had mild COPD. Old age(more than 60's) and male were significant risk factors of COPD. But smoking, drinking and Sasang Constitution were not risk factors of COPD. But there were many Soeumin who had mild COPD in terms of Sasang Constitution irrespective of sex. 4. Conclusions: Low BMI(<23kg/m2) and low income also were significant risk factors. And Sasang Constitution might be the variable to manage COPD patients, but more researches are needed.

  • Pulmonary epithelioid hemangioendothelioma (PEH) is a rare, low-to-intermediate malignant tumor of endothelial origin. Computed tomography (CT) findings of PEH demonstrate multiple small bilateral nodules; however, to the best of our knowledge, there were no reports on PEH coexisting with other malignancies. Here, we reported on a case involving PEH in a patient with colon cancer and breast cancer which was misconceived as pulmonary meta- stasis. A 63-year-old woman who suffered from constipation for 2 weeks visited our hospital. Colonoscopy showed a large mass with obstruction on hepatic flexure. The histological diagnosis was adenocarcinoma of the ascending colon. Multiple nodules in both lungs and breast were observed on a chest CT scan. A core biopsy of a breast nodule was performed and a diagnosis of invasive ductal carcinoma of the left breast was made. Pulmonary nodules observed on the chest CT scan was considered as pulmonary metastasis from colon or breast cancer. Laparoscopic right hemicolectomy was performed. At the same time, wedge resection of the lung was performed and pathological diagnosis was PEH. Radiologic features of PEH were difficult to distinguish from lung metastasis. Therefore the author reported a rare case involving PEH in a patient with primary malignancy of colon and breast.

  • This study was performed to determine the effect of green tea on the late biological effect (survival, hematological change, carcinogenesis) of mice irradiated with 3 Gy of gamma-radiation. There was little difference in body weights between normal and irradiated mice. Survival rate were decreased in irradiated mice and the survival rate and mean survival time of the groups treated with green tea were far better than the irradiation control group. An elevation of mean number of total leukocyte or lymphocyte counts was seen at week 12 of the group treated with green tea. Stimulated recovery by the extract from green tea was also observed in thrombocyte. Main gross findings of irradiated mice were appeared as enlargement of spleen, thymus and liver, tumorous nodules in lung and cyst or mass in ovary. Microscopically, there were various findings including hematopoietic and lymphoid tumor, lung cancer, ovarian cancer and cancer of other lesions. Green tea reduced the incidence of tumor development. Further studies are needed to characterize better the protective nature of active compounds.

  • Tumor of the trachea are uncommon. Trachea tumor are usually diagnosed late in their natural history, because the tracheal lumen may be extensively involved before symptoms occur, and because symptoms may be confused with those of asthma. Some 19% to 29% of the trachea tumor have laryngeal or lung malignancy. Squamous carcinoma is by far the most frequent among tracheal tumor, although adenocarcinoma and oat cell carcinoma have been described so. Oat cell carcinoma in the trachea are aggressive tumors as they are in the lung and elsewhere. Oat cell carcinoma as well as squamous cell carcinoma are related with tobacco exposure. We presented a case of small cell carcinoma nearly obstructing the trachea and right main bronchus which was partially removed after bronchoscopic ethanol injection, along with a review of the literature.

  • We experienced one case of combined mixed germ cell tumor and angiosarcoma metastasis to the lung within the mediastinum. He was 19-year-old male, complained of hemoptysis, coughing, purulent sputum and weight loss for 2 months prior to adimission. The patient underwent open thoracotomy, but we couldn't resect the mass completely, because of tumor encroachment on adjacent mediastinal structures. He began radiation therapy involving the right lung but had no response to therapy.
