Pulmonary function test is used as a guideline for safe pulmonary resection without complications. Usually FEVl lower than 1 liter is considered as a contraindication of lobectomy. Therefore, the curative operation of resectable lung cancer can not be performed in the case of poor pulmonary functions. Nowadays, there are some arguing points about the value of preoperative PFTs before the pulmonary resection. We performed a right pneumonectomy for stage H lung cancer in a patient with poor lung function test; FVC 2.17L, FEVl 0.97L, FEVl/FVC 44%, FEF 25-75％ 0.42L/sec, MVV 28L/min, TLC 5.18L, RV 2.99. During 4 months follow up, the patient had been tolerable. The follow up PFTs at postoperative 3 months 18 days showed up as follows; FVC 1.20L, FEVI 0.63L, FEVl/FVC 53%, FEF 25-75% 0.31L/sec, MVV 25L/min, TLC 3.80L, RV 2.33L.

The purpose of this study was to examine the effects of trunk mobilization and stretching activities on respiratory function, trunk posture, and physical fatigue for elderlies with restrictive lung diseases and related respiratory impairment. The present study was conducted with ten subjects, participating for eight weeks between January and November 2014. Subjects performed trunk mobilization and stretching routines for 30 minutes per day for three days each week. The study results showed that there were significant improvements in FVC and FEV1, trunk posture, trunk movement and physical fatigue(p<.05). The study results verified that trunk mobilization and stretching activities can be used as respiratory orthopedic manual therapy to improve respiratory function, trunk posture, trunk movement and physical fatigue simultaneously for elderly with respiratory impairment. Continuous studies through therapeutic convergence with the exercise field along with the respiratory orthopedic manual therapy that used in this study for elderly people with restrictive lung diseases will be necessary for the future.

Purpose : The purpose of this study was to investigate the effects of transverse abdominal muscle contraction on pulmonary function in supine position. Methods : 10 female and 10 male college students were recruited this study. Pulmonary Function test was measured with QUARK SPIRO. To check the changes in lung function with transverse abdominal muscle contraction, we tested pulmonary function in the supine, with and without transverse abdominal muscle contraction. While the transverse abdominis was activating, we investigate in the change of forced expiration. All statistical analyses were performed using SPSS Statistics VER.12.0 for window version p-values less than 0.05 were used to identify significant differences. Statistical analysis was used Paired t-test to know difference between activated and non-activated TrA of forced expiration. Results : The subject with transverse abdominal muscle contraction showed significant increments in variable of FVC, FEV1, PEF compared to the pre-intervention results (p<0.01). Conclusion : These results indicate that spontaneous contraction of the TrA helps pulmonary function. And the selective contraction of the transverse abdominis at the end of forced inspiration makes increases in the lung capacity.

Mechanical ventilation is usually the treatment of choice for severe respiratory failure associated with trauma. However, in case of severe hypoxia, mechanical ventilation may not be sufficient for gas exchange in lungs. Patients with Acute Respiratory Distress Syndrome (ARDS) undergo difficulties in oxygen and carbon dioxide exchange. Extracorporeal Membrane Oxygenation (ECMO) is the ideal therapeutic option for those patients with severe traumatic injuries. ECMO allows lungs to reserve their functions and decreases further lung injuries while increasing survival rate at the same time. We report two cases of patients with traumatic ARDS and Multiple Organ Failure including compromised heart function. The preservation of lung function was successful using ECMO therapy.

Lung function reportedly declines with age and that this decline is accelerated during disease progression. However, a recent study showed that the decline might peak in the mild and moderate stage. The prognosis of chronic obstructive pulmonary disease (COPD) can be improved if the disease is diagnosed in its early stages, prior to the peak of decline in lung function. This article reviews recent studies on early COPD and the possibility of applying the U.S. Preventive Services Task Force recommendation 2008 and 2015 for early detection of COPD in Korea.

In order to study the effect of air pollution on the ventilatory function of lung, pulmonary function studies were carried out in middle school students (male) living isn Sasang industrial area more than 10 years, and were compared with those of control group. The following results were obtained; 1. Lung capacities were normal in observed & control group, and were not significantly different between two groups. 2. The respective parameters of ventilatory function test of observed group were smaller than that of control group, but FVC, $FEV_1$, $FEV_1/FVC$, FEF 25-75%, Vmax 50, MVV of two groups were normal. 3. PEFR, Vmax 25, Vmax 75 of observed group were significantly decreased, and there were statistically significant differences between two groups in FEF 25-75% (p < 0.01), Vmax 25 (p < 0.05), Vmax 50 (p < 0.01), Vmax 75 (p < 0.05), PEFR (p < 0.05) and MVV (p < 0.02).

Pulmonary function test is a group of tests which are composed of measurement for lung function. Thy are spirometry, blood-gas analysis, lung volumes, exercise test, diffusion capacity, and bronchial challenge test. In this article, I will review the pulmonary function test and it's application in terms of clinical aspect and insurance medicine. The standard spirometric indicies are forced vital capacity(FVC), forced expiratory volume at 1 second(FEV1), and the ratio of FEV1 over FVC(FEV1/FVC). If the value of FEV1/FVC less than 70%, the examinee has obstructive ventilatory dysfunction.

MG53 is a member of the TRIM-family protein that acts as a key component of the cell membrane repair machinery. MG53 is also an E3-ligase that ubiquinates insulin receptor substrate-1 and controls insulin signaling in skeletal muscle cells. Since its discovery in 2009, research efforts have been devoted to translate this basic discovery into clinical applications in human degenerative and metabolic diseases. This review article highlights the dual function of MG53 in cell membrane repair and insulin signaling, the mechanism that underlies the control of MG53 function, and the therapeutic value of targeting MG53 function in regenerative medicine.

Background: Cigarette smoke induced release of iron could alter iron metabolism in the lungs of chronic smokers and contribute to the increase in the total oxidative burden on the lungs of smokers. In previous studies, ferritin levels of bronchoalveolar lavage fluid in smokers were elevated. The aim of the present study was to investigate the relationship between serum ferritin concentration, smoking and lung function in Korean people. Methods: This study was based on the data acquired in the second year (2008) of the Forth National Health and Nutrition Examination Survey that was conducted from 2007 to 2009. The analysis included 2,244 subjects who were older than 20 years and had complete data from both lung function test and serum ferritin concentration. Among participants, 1,076 were male and 1,168 were female. Results: Mean serum ferritin concentrations in males were $120.3{\pm}80.1{\mu}g/L$ and $47.9{\pm}39.8{\mu}g/L$ in females. There were no differences in serum ferritin concentrations between non-smokers and smokers after adjusting for age, body mass index, and amounts of alcohol. Serum ferritin concentrations were associated with smoking amounts by simple linear regression but not associated with smoking amounts after adjustment with age, body mass index, and amounts of alcohol in both males and females. Lung function was not associated with serum ferritin concentrations. Conclusion: Our data suggested that serum ferritin concentrations are not related with smoking and lung function.

Aims: To investigate changes in cellular immune function of patients with lung cancer before and after cytokine-induced killer (CIK) cell therapy and to identify variation effects on overall survival (OS) and progression-free survival (PFS). Materials and Methods:A total of 943 lung cancer patients with immune dysfunction were recruited from January 2002 to January 2010, 532 being allocated to conventional therapy and 411 to CIK therapy after a standard treatment according to the NCCN Clinical Practice Guidelines. All the patients were investigated for cellular immune function before and after therapy every three months. and clinical prognostic outcomes were analyzed. Results: After six courses of treatment, immune function was much improved in patients receiving CIK cells therapy as compared to controls. The percentages of recurrence and/or metastases for patients undergoing CIK cell therapy was 56.2% and 49.1% respectively but 78.6% and 70.3% among controls (p<0.001). The median OS times for CIK cell therapy and control groups were 48 and 36 months respectively. The OS rates at 12, 36, 60, 84 months in CIK treated patients were 97.8%, 66.9%, 27.7%, and 4.1% while they were 92.3%, 44.5%, 9.2%, and 1.5% in controls. OS and PFS were significantly different by log rank test between the two groups and across the three immune improvement classes. Conclusions: The immune function of lung cancer patients was improved by CIK cell therapy, associated with an increase in the OS rate and extension of the time to recurrence and/or metastasis.
