Background : Patients with locally advanced non-small cell lung cancer are often treated with radiation alone or in combination with chemotherapy. Both modalities have a potentially damaging effect on pulmonary function. In order to examine changes in the cardiopulmonary exercise function of patients with locally advanced non-small cell lung cancer before and after conventional radiotherapy, we conducted a prospective study involving patients with such cancer, that had received radiation therapy. Method : Resting pulmonary function test, thoracic radiographic finding and cardiopulmonary exercise test(CPET) were assessed prior to and 4 weeks following radiation therapy in 11 male patients with locally advanced non-small cell lung cancer. Patient with endobronchial mass were excluded. Results : The forces vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$ and maximal voluntary ventilation (MVV) did not decreased between before and 4 weeks after radiation but the diffusing capacity (DLCO) had decreased by 11% 4 weeks after radiation, which was not statistically significant. No changes in maximal oxygen consumption ($VO_2$max), carbon dioxide production ($VCO_2$), exercise time and work load were attributed to radiation therapy. Follow up cardiopulmonary exercise testing revealed unchanged cardiovascular function, ventilatory function and gas exchange. No difference in cardiopulmonary exercise test performance was observed between pre- and post-radiation. Conclusion : Cardiopulmonary exercise function did not decrease within the short-term after the radiation of patients with locally advanced non-small cell lung cancer.

Studies of pulmonary function using spirometry were performed before and after pneumonectomy for inflammatory lung diseases from 1985 to 1990 at the Pusan Paik Hospital, Inje Medical College. Fifty-two patients were evaluated ; 33 tuberculosis, 17 bronchiectasis, 2 abscess, and 1 actinomycosis. All patients had preoperative and postoperative FVC, FVC[% predicted], FEV1, %FEV1, MVV and MVV[%predicted] determinations. And above datas were compared each other statistically with applying of the paired t-test. The results were obtained as follows : there were significant decreased after surgery in the values of FVC, FVC[% predicted], MVV, and MVV[% predicted], but the values of FEV1, and %FEV1 were no significant changes after surgery.

Objective : Cardiopulmonary exercise testing in patients with heart and lung problems is used to assess functional capacity, evaluate responses to medical treatment, plan for exercise therapy, assess progression of disease process, and determine prognosis. Particularly in the patients with lung cancer, the exercise pulmonary function test gives significant physiologic assessment of the lung resection candidate. Common exercise modalities are running and cycling. Until now, the comparison of two tests mainly has been done in normal person and patients with cardiac diseases. This study is designed to compare the treadmill and bicycle exercise pulmonary function test in patients with respiratory diseases. Methods : Twenty one patients underwent a progressively incremental exercise test to the symptom-limited stage with the treadmill (Vmax29 Sensor Medics, USA) and the bicycle(model No. 2,900 Sensor Medics, USA) with 7 days apart between the two tests. Measurements were made of the metabolic, cardiorespiratory parameters, blood gases, and symptoms. Results : The results of the treadmill exercise showed significant elevation in the $VO_2$max, VEmax, and anaerobic threshold compared to those of bicycle exercise. In contrast, the results of the breathing and heart rate reserve showed the reverse. Conclusion : These results suggest that the type of exercise should be taken into consideration when interpreting exercise test in patients with respiratory diseases.

Background: The evaluation of candidates for successful lung resection is important. Our study was conducted to determine the preoperative predictors of postoperative mortality and morbidity in lung cancer patients with impaired lung function. Method; Between October 1, 1995 and August 31, 1997, 36 lung resection candidates for lung cancer with $FEV_1$ of less than 2L or 60% of predicted value were included prospectively. Age, sex, weight loss, hematocrit, serum albumin, EKG and concomitant illness were considered as systemic potential predictors for successful lung resection. Smoking history, presence of pneumonia, dyspnea scale(l to 4), arterial blood gas analysis with room air breathing, routine pulmonary function test were also included for the analysis. In addition, predicted postoperative(ppo) pulmonary factors such as ppo-$FEV_1$ ppo-diffusing capacity(DLco), predicted postoperative product(PPP) of ppo-$FEV_1%{\times}$ppo-DLco% and ppo-maximal $O_2$ uptake($VO_2$max) were also measured. Results: There were 31 men and 5 women with the median age of 65 years(range, 44 to 82) and a mean $FEV_1$ of $1.78{\pm}0.06L$. Pneumonectomy was performed in 14 patients, bilobectomy in 8, lobectomy in 14. Pulmonary complications developed in 10 patients; cardiac complications in 3, other complications(empyema, air leak, bleeding) in 4. Twelve patients were managed in the intensive care unit for more than 48 hours. Two patients died within 30 days after operation. The ppo-$VO_2$max was less than 10 ml/kg/min in these two patients. MVV was the only predictor for the pulmonary complications. However, there was no predictor for the post operative death in this study. Conclusions: Based on the results, MVV was the useful predictor for postoperative pulmonary complications in lung cancer resection candidates with impaired lung function In addition, ppo-$VO_2$max value less than 10 ml/kg/min was associated with postoperative death, so exercise pulmonary function test could be useful as preoperative test. But further studies are needed to validate this result.

Fibrothorax is the end stage of chronic pathologic processes of pleura such as hemothorax, empyema, or tuberculous effusion. The pleural space become adherent and obliterated, and the lung parenchyma is covered by a thick, fibrous, unexpandable "peel", so the lung function is diminished markedly with impaired ventilation and oxygenation. Constrictive pericarditis is often accompanied fibrothorax, also cardiac and hemodynamic function is deteriorated. Surgical relief of these fibrous peels causes remarkable improvement in pulmonary function, cardiac and hemodynamic function, and subjective symptoms. We experienced a case of bilateral fibrothorax combined with constrictive pericarditis which occured 3 years after bilateral tuberculous effusion. Decortication and percardiectomy were done at the same time through bilateral submammary thoracotomy with sternal transection. Comparing postoperative Peripheral venous pressure, Circulation time, Pulmonary function test, Arterial blood gas analysis, Subjective symptoms with preoperative conditions showed noticeable improvement.provement.

Purpose: This study is aimed to analyze the trend of research on pulmonary rehabilitation of patients with COPD (Chronic Obstructive Pulmonary Disease), and to suggest a direction for future research of pulmonary rehabilitation of COPD. Method: A total of 39 studies published from 1991 to 2002 were examined according to the year of publication, type of journal, characteristics of patients, rehabilitation program, research design, and instruments and research findings. Results: 1) The number of studies related to pulmonary rehabilitation of COPD patients has rapidly increased since 1996's (87.18%) 2) There were 10 studies published in the chest. There were 6 studies published in domestic journals and 33 studies published in international journals. 3) The samples in the studies were mostly outpatients whose lung function was moderate. 4) The total period of the pulmonary rehabilitation program shown in the literature was 5 to 12 weeks. The programs included exercise interventions, educational interventions and psychosocial interventions. 5) The outcomes of the pulmonary rehabilitation were measured with lung function, 6-minute walk test, dyspnea, and chronic respiratory disease questionnaire. Research findings were found to be effective on 6-minute walk test, dyspnea, and chronic respiratory disease questionnaire but not on lung function. Conclusion: Based on these findings, pulmonary rehabilitation should be further emphasized, and standardized protocols and community based pulmonary rehabilitation programs need to be provided. More qualitative research should also be conducted in the future to describe the experiences of the pulmonary rehabilitation of patients with COPD.

This study was conducted to help oriental medical prevention program policy for improvement of public health in a local community. We have researched respiratory diseases and demands for oriental medical cold preventing therapy of some residents in Chung-Buk. We have conducted individually face-to-face interviews through standardized questionnaires to 141 residents of two towns (76 in Haeng-jung, 65 in Gu-mi) under the jurisdiction of Chung-won Public Health Center. The senior aged over 65 was 53.9%, which was a little more than the average senior age. The rate which could be diagnosed as a disorder of lung function was 2.97% by Lung Function Test. The participants diagnosed as Asthma accounted for 17.9% by Symptom Based Easy Asthma Diagnosis of Easy Asthma Management(EAM). The participants who had intentions of participating in oriental medical cold preventing therapy accounted for 58.6%. And among the oriental medical cold preventing therapy the preference for acupuncture and moxibustion was 77.1 %, which was much higher than any other thing. It is thought that people still have little understanding about the oriental medical cold preventing therapy. Therefore it is considered that the Korean government should try to establish well-organized cold preventing system on the basis of Oriental Medical theory for a local community.

This study was conducted to identify relationships between lung function disorders and Metabolic Syndrome(MetS) that have common comorbidities such as Cardio Vascular Diseases(CVD). According to the hypothesis that there may be a significant relationship between them, analyses were conducted to identify the proper management point for those diseases. Overall, 53,829 data were taken from KNHANES 2008-2013. Included data were PFT(Pulmonary Function Test) done and age over 40. All the 14 confounders applied, only 8,137 cases (M:3,951, F:4,186) were left. Low pulmonary function was divided into two categories, obstructive and restrictive patterns, based on the Global Initiative for Chronic Obstructive Lung Disease(GOLD) criteria, while MetS was defined based on the revised NCEP-ATPIII criteria. The relationships between those diseases were analyzed using logistic regression analysis. In addition, for the prevalence rate, cross-tab analysis were conducted. There were no significant relationships observed between obstructive lung disease and MetS, but a restrictive pattern had a meaningful relationship with MetS. Specifically, MetS showed a higher prevalence rate for both obstructive and restrictive pattern patients than the control group. Restrictive pattern patients showed a higher prevalence rate to MetS than obstructive patients. Overall, restrictive lung patterns showed a meaningful association with MetS, but not with obstructive patterns. Additionally, the prevalence rate of MetS among restrictive patients was higher than among obstructive patients.

Background: Diseases affecting the lungs and airways contribute significantly to the global burden of disease. The problem in low- and middle-income countries appears to be exacerbated by a shift in global manufacturing base to these countries and inadequate enforcement of environmental and safety standards. In Ghana, the potential adverse effects on respiratory function associated with occupational wood dust exposure have not been thoroughly investigated. Methods: Sixty-four male sawmill workers and 64 non-woodworkers participated in this study. The concentration of wood dust exposure, prevalence and likelihood of association of respiratory symptoms with wood dust exposure and changes in pulmonary function test (PFT) parameters in association with wood dust exposure were determined from dust concentration measurements, symptoms questionnaire and lung function test parameters. Results: Sawmill workers were exposed to inhalable dust concentration of 3.09 ± 0.04 mg/m³ but did not use respirators and engaged in personal grooming habits that are known to increase dust inhalation. The sawmill operators also showed higher prevalence and likelihoods of association with respiratory symptoms, a significant cross-shift decline in some PFT parameters and a shift towards a restrictive pattern of lung dysfunction by end of daily shift. The before-shift PFT parameters of woodworkers were comparable to those of non-woodworkers, indicating a lack of chronic effects of wood dust exposure. Conclusions: Wood dust exposure at the study site was associated with acute respiratory symptoms and acute changes in some PFT parameters. This calls for institution and enforcement of workplace and environmental safety policies to minimise exposure at sawmill operating sites, and ultimately, decrease the burden of respiratory diseases.

PURPOSE: The aim of this study was to examine the effect of air stacking exercise on lung capacity, activities of daily living, and walking ability in elderly adults. METHODS: A total of 27 subjects were randomly assigned to an experimental group (EG=13) or a control group (CG=14). Subjects in the experimental group participated in an active pulmonary rehabilitation program. 5 days a week for 4 weeks. The active pulmonary rehabilitation program was composed of an air stacking exercise with an oral nasal mask and manually assisted coughing. Conventional pulmonary rehabilitation exercises, such as, cough exercise, deep breathing, and abdominal muscle strengthening exercises were performed by both groups. Pulmonary function parameters, peak cough flow (PCF), and oxygen saturation were measured and the 6-minute walk test and Korean version of the modified Barthel index (K-MBI) scores were applied. RESULTS: Significant intergroup differences were observed for forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) results after intervention (p<.05), and for 6 minute walk test and PCF results after intervention and at 2-week follow-up visits (p<.05). Post hoc test results showed significant differences in K-MBI, 6-minute walk test, and FEV1 in the experimental group after intervention (p<.05). FVC values were significantly higher after intervention and at 2-week follow-up visits versus pre-intervention (p<.05). PCF values were also significantly higher after intervention and remained significantly higher at 2-week follow-up visits (p<.05). CONCLUSION: Air stacking exercise in elderly adults improves lung capacity and exercise tolerance.
