Sarcoidosis is a multisystemic granulomatous disease with an of unknown etiology, involving bilateral hilar lymphadenopathy, pulmonary, skin and eye lesions. However, involvement of the endocrine system in sarcoidosis is quite rare, and the coexistence of both diseases is extremely unusual. We describe a 60-year-old woman presenting with sarcoidosis and Graves' disease. She was admitted for evaluation of dry cough, dyspnea, palpitation and general weakness. Both thyroid glands were enlarged diffusely. The thyroid function tests showed suppressed serum thyrotropin and an increased thyroid hormone level. The levels of the TSH receptor antibody, anti-thyroglobulin antibody and anti-microsomal antibody were higher than normal. The radionuclide scan($^{131}I$) showed increased iodine uptake. The chest X-ray revealed pulmonary hilar enlargement and high resolution CT showed both hilar lymph nodes enlargement and tiny parenchymal nodules. The transbronchial lung biopsy showed a noncaseating granuloma without necrosis. We report this case of pulmonary sarcoidosis plus Graves' disease with a review of the relevant literatures.

Bronchiolitis interstitial pneumonitis (BIP), an unclassified and newly described interstitial pneumonia, has a combined feature of prominent bronchiolitis, interstitial inflammation, and fibrosis. It is distinct from bronchiolitis obliterans or bronchiolitis obliterans organizing pneumonia (BOOP). BIP has a better prognosis than common cases of interstitial pneumonia. However, BIP has a poorer prognosis than BOOP. BIP's response to corticosteroids is not as successful as BOOP's response to this treatment. We encountered the case of a 31-year-old woman with BIP with an initial presentation of dyspnea and a cough that had lasted for 3 months. The patient's chest CT scan demonstrated patchy ground glass opacities and multiple ill-defined centrilobular nodules in both lungs, suggesting military tuberculosis or nontuberculous mycobacterial infection. A video-assisted thoracoscopic lung biopsy resulted in the diagnosis of BIP. Clinical symptoms, pulmonary lesions, and pulmonary function tests were improved after oral glucocorticoid therapy.

A large number of studies have indicated associations between the impairment of respiratory health and exposure to ambient air pollutants such as ozone (O$_3$) , nitrogen dioxide (NO$_2$) , sulfur dioxide(SO$_2$) , particulate matters (PM$\_$10/). To evaluate this associations, we used the pulmonary function tests (peak expiratory flow rate : PEFR) by mini-wright peak flow meter and counting neutrophils in the nasal lavage (NL) as biomarker. From 15 June to 16 July 1998, for the workers in the highway tollgates, PEFR and NL were measured three times daily and twice per week. and association between the level of air pollutants and PEFR and NL were analyzed using the multiple regression model and the poisson regression model respectively. The results indicated that the effects of all measured air pollutants (SO$_2$, NO$_2$, O$_3$, PM$\_$10/) were not significantly associated with the value of PEFR. On the other side, SO$_2$, NO$_2$, PM$\_$10/ were significantly associated with the number of neutrophils in NL. The increase in SO$_2$, NO$_2$of 10ppb and in PM$\_$10/ of 10$\mu\textrm{g}$/m$^3$was associated with 24%, 21%, 35% increases in neutrophil counts. But the ozone exposure was not associated with NL.

We have experienced a case of sarcoidosis appearing asymmetrical diffuse interstitial lung lesions with multiple lymphadenopathy. This patient was a 57 year-old female who had been in good health until 2 months ago. At that time she noted the onset of an exertional dyspnea and weakness. Pulmonary function tests showed moderate obstructive pattern with mild decreased DLco. In the chest CT, multiple lymphadenopathy with small nodular lesions are scattered, and the impression was a metastatic lymph nodes with lymphangitic carcinomatosis. In bronchofiberscopy, we noted luminal narrowing by extrinsic compression in the right middle and lower lobe bronchi. And microscopic examination of by bronchofiberscopic biopsy showed chronic inflammation. Thus we performed subcarinal and tight supraclaviclar lymph nodes aspiration biopsy cytology, and that revealed class 0 and class 1, respectively. Finally, we performed an excisional biopsy for the right scalene lymph node, which revealed the specimen as a noncaseating granuloma. The angiotensin convecting enzyme level was overt two folds compared to normal value. And the patient had negative PPD skin test and hyperglobulinemia. After 18 weeks treatment with prednisone, the signs and symptoms which the patient clad suffered from, disappeared.

To confirm diagnosis and to set proper therapeutic strategy, open lung biopsies were done in 57 patients who were suspected for diffuse interstitial lung disease from January 1985 to December 1994. Among them, 35 were male and 22 were female[M:F=l.6: 1 and mean age of the patients is 53.5$\pm$ 2.3[24-81 years. Tissue for histologic studies were obtained from left lung in 33, from right lung in 24according to the distributions of the pathology. Preoperative diagnostic work-up`s were chest X-ray, CT[HRCT scan, sputum study, bronchoscopy[BAL, TBLB and PTNA and all of them were unsuccessful to confirm diagnosis. In comparison of pulmonary function tests between preoperative and postoperative values, there were no significant differences in FVC, FEV1, FEV1/FVC[p 0.05 but in AaDO2[p[0.05 . Postoperative complications including atelectasis, wound infection, pulmonary edema and respiratory insnfficiency, were shown in 5 cases[8.8% , and two of them were died of respiratory failure and sepsis[mortality rate 3.5% . Pathologic diagnosis was confirmed in 53 cases postoperatively but it was undetermined in 4[diagnostic yield rate 93.0% . In comparison between preoperative clinical diagnosis and postoperative pathologic diagnosis, new diagnosis were made in 17 cases[29.8% and preoperative tentative diagnosis were confirmed histologically in 36 cases[63.2% . In 4 cases[7.0% , however, diagnoses were not confirmed after biopsies. Therapeutic plans were reset in 46 cases[80.7% in accordance with the final diagnosis.In conclusion, open lung biopsy is recommended for a specific diagnosis and proper therapeutic plan in diffuse interstitial lung diseases because of its high diagnostic yield Irate and it`s relatively low morbidity and mortality rate in these tompromised patents.

Allergic bronchopulmonary aspergillosis (ABPA) is a complex clinical entity resulting from an allergic immune response to Aspergillus species, and most often occurs in patients with asthma. ABPA is rarely observed in the absence of asthma, which is, in fact, the principal criterion for its diagnosis. Our patient was a 53-year-old woman with no history of bronchial asthma. She presented with a 1-month history of cough, mucopurulent nasal discharge, and localized pulmonary consolidation. Peripheral blood eosinophilia and elevated serum IgE were observed. Sinus radiography showed right maxillary sinusitis. Pathologic examination of bronchoscopic biopsy specimens revealed conglomerates of fungal hyphae. Pulmonary function and bronchial provocation tests were within normal ranges. The patient was successfully treated for 3 months with itraconazole and oral prednisolone. There has been no evidence of recurrence over a 7-month follow-up. ABPA coupled with sinusitis in a nonasthmatic patient is a very rare occurrence and warrants reporting.

The present investigation was carried out to determine the efficacy and safety of Abutilon indicum (A. indicum) (Eng: Country Mallow, Fam: Malvaceae) in patients of bronchial asthma. Dried aerial parts of A. indicum were finely powdered and given in the dose of 1 gm tid to 30 patients of either sex in the range of 15 - 80 years with mild to moderate bronchial asthma with or without any concurrent medication. The respiratory functions (FVC, $FEV_{1}$, $FEF_{25-75%}$and MVV) were assessed using a spirometer prior to and after 4 weeks of treatment. Efficacy of the drug in improving clinical symptoms and severity of asthmatic attacks was evaluated by interviewing the patient and by physical and hematological examination at the end of the treatment. 4 weeks treatment with the drug showed statistically significant improvement in various parameters of pulmonary functions in asthmatic subjects. Also significant improvement was observed in clinical symptoms and severity of asthmatic attacks. None of the patient showed any adverse effect with A. indicum. The results of the present study suggest the usefulness of A. indicum in patients with mild to moderate bronchial asthma.

Background: To evaluate the risk factor of pneumothorax (PNX) which is the most common complication of CT-guided needle aspiration of the lung, we have examined the frequency of PNX according to the presence of obstructive ventilatory impairment determined by pulmonary function tests. Methods: A comparative study of analysis of forecd expiratory volume and folw-volume curves, and determinations of diffusing capacity taken before procedure were made between each 16 cases with PNX and controls with no PNX. Each of the control group was matched for sex, age, height, and size and depth of lesion with the former. Results: 1) In comparison of vital capacity and parameters derived from forced expiratory volume curve between two groups, VC and FVC were not significantly different, whereas $FEV_1$, $FEV_1$/FVC%, and FEF25-75% showed a significant decrease in the PNX gorup. Also, in the PNX group, all the observed values of parameters analyzed from flow-volune curve were siginificantly reduced in the PNX group compared with those in the control group. 2) The diffusing capacity tended to decrease along with varying individual differences in the PNX group. 3) Patients who had obstructive ventilatory impairment according to the results of pulmonary function tests experienced a twofold increase in the frequency of PNX and a sixfold increase in the frequency of chest tube drainage for treatment of PNX compared with those whose results were normal. Conclusion: These findings suggest that the exact evaluation of obstructive lung disease determined by pulmonary function test be considered assessing a pastient's risk for PNX in the patients who will take the CT-guided needle aspiration of the lung.

Background: It is well known that cigarette smoking is the risk factor of lung cancer, chronic obstructive pulmonary disease and ischemic heart disease. But there are few reports about the immediate effect of cigarette smoking on the cardiopulmonary functions. The serum level of carbon monoxide increases during cigarette smoking. It is known that carbon monoxide increases respration rate, heart rate and cardiac output, with decrease in maximal oxygen consumption. So we have studied to determine the immediate effects of cigarette smoking on the cardiopulmonary function during exercise. Method: Thirteen healthy smoking male subjects were included in this study. Each subject was undertaken pulmonary function test and incremental exercise test on two separate days, one without smoking (control) and the other after smoking three cigarettes per hour for five hours. The order of the two tests was randomized. Results: 1) The mean age of the subjects was $25{\pm}4.9$ year-old and the mean smoking history was $6{\pm}5$ pack years. 2) The mean blood level of carbon monoxide on the smoking day was higher than that on the nonsmoking day ($5.97{\pm}1.34%$ vs. $1.45{\pm}0.83%$; p<0.01). 3) The mean maximal oxygen consumption on the smoking day was lower than that on the nonsmoking day ($2.09{\pm}0.32$ L/min vs. $2.39{\pm}0.32$ L/min; p<0.05). 4) The mean anaerobic threshold on the smoking day was lower than that on the nonsmoking day ($1.33{\pm}0.24$ L/min vs. $1.53{\pm}0.20$ L/min; p<0.05). 5) The mean heart rate at rest on the smoking day was higher than that on nonsmoking day ($84.38{\pm}11.06$ beats/min vs. $75.46{\pm}5.83$ beats/min; p<0.05). But the means of maximal heart rate on both days were not different. 6) The pulmonary function tests were similar on both days. Conclusion: There was no change in pulmonary function test, but the maximal oxygen consumption and anaerobic threshold were decreased on the smoking day. So it was concluded that cigarette smoking impaired the cardiovascular functions immediately during exercise.

This study investigated the symptoms, medical and occupational history of 424 workers of 5 reactive dye Industries in the Inchon area in Korea. The study was performed on March 6 and July 19, 1989. The tests applied to the subjects were : serum total IgE, specific IgE, skin prick test with 7 inhalatory antigens, pulmonary function test, chest X-ray, methacholine test, and bronchoprovocation test. The workers were classified according to these tests into 4 groups (healthy, realtively healthy, need careful medical observation, and occupational asthma), and were compared in terms of the group characteristics and the symptom prevalence. The prevalece of occupational asthma of workers in reactive dye was 5.9% Significant differences were observed among the 4 groups. The groups were significantly different in the variables of sex and duration of smoking among their general characteristics ; and dyspnea, wheezing, chest pain, cough, nasal symptoms and sore throat among symptoms ; asthma, bronchitis, and other respiratory diseases with respect to their past medical history. This study suggests that we should pay special attention to the workers exposed to the risk of occupational asthma.
