Abstract
Plant seeds, as those from milk thistle (Silybum marianum), are a valuable source of nonpolar and polar compounds with potentially interesting biological activity. The main nonpolar compounds are triglycerides, which are also the main components of all vegetable oils. In addition, specific polar compounds - flavonolignans, called silymarin, have been found in large amounts in milk thistle seeds extract. These flavonoids derivatives have different biological activity, for instance hepatoprotective effects. In order to extract and analyze both nonpolar (triglycerides) and polar compounds (flavonolignans) from milk thistle seeds through a sequential methodology, an on-line supercritical fluid extraction - supercritical fluid chromatography (SFE-SFC) method was developed. Different ways of transferring the extracts from SFE to SFC (i.e. direct on-column transfer and loop transfer) were compared, and particularly for their effect on chromatographic quality. In this respect, nonpolar and polar compounds caused different issues, especially as polar compounds required a significant portion of co-solvent in the extraction step, favoring early elution in the chromatographic column. First, on-line SFE-SFC was used for triglycerides analysis and allowed the comparison of transfer modes. Then, on-line kinetics were performed to measure defatting time before polar molecules extraction. Finally, the eventual benefit of loop transfer was also investigated for the analysis of flavonolignans, polar molecules whose analysis can be difficult by on-line SFE-SFC. The aim of this paper is to discuss the versatility of on-line SFE-SFC and how challenging the coupling can be, especially when both non-polar and polar molecules must be analyzed independently in a single sample.

Abstract
A woman in her 70s was diagnosed with cancer of pancreatic head. She underwent subtotal stomach-preserving pancreatoduodenectomy. Moderately differentiated adenocarcinoma, positive peripancreatic exfoliation surface, and R1 resection was diagnosed by histopathological examination. She underwent adjuvant chemotherapy(S-1), but 5 years and 6 months after the operation, a single nodule(16×9 mm)appeared on anterior segment of left lung. She underwent thoracoscopic left upper lobectomy on suspicion of primary lung cancer. Adenocarcinoma consistent with pancreatic cancer metastasis was diagnosed by histopathological examination. She didn't choose chemotherapy after second operation. 1 year and 1 month after the left pneumonectomy, a single nodule(11×10 mm)reappeared in lateral basal segment of right lung. Although it was difficult to diagnose whether it was primary or metastatic, she decided to undergo thoracoscopic partial lung resection. Histopathological examination revealed that the histology was similar to that of the previous lung lesion and was consistent with pancreatic cancer metastasis. After that, she also didn't choose chemotherapy. She has been alive for 7 years and 7 months after her first pancreatic cancer surgery without any new obvious recurrence.

Abstract
Here, we report a case of malignant pleural mesothelioma (MPM) that was very difficult to diagnose. A 62‐year‐old woman with a surgical history of recurrent bilateral pneumothorax was admitted to our hospital with severe dysphagia. Computed tomography (CT) detected stenosis in the lower esophagus. Immunohistochemical examination of a biopsy sample from the stenotic region was suggestive of MPM. Chemotherapy was initiated, but the patient soon weakened and died. Autopsy revealed atypical cells, identical to those seen in the biopsy sample which had spread into the stenotic esophagus and entire thoracic cavity. Although neither pleural thickening/nodules nor asbestos bodies were observed, we finally diagnosed the tumor as a biphasic‐type MPM. We re‐examined previous surgical specimens of pneumothorax and acknowledged foci of bland mesothelial cell proliferation which had the same pathological findings as tumor cells at autopsy. The lack of asbestos exposure and pleural thickening, an initial manifestation of pneumothorax, and faint cytological atypia prevented an early diagnosis. In cases of recurrent pneumothorax in elderly patients, MPM should be included in the differential diagnosis.

Abstract
Objective Nocturnal desaturation is common in patients with chronic respiratory disease and often worsens the prognosis. Therefore, it should be diagnosed accurately and appropriately treated. The aim of this study was to clarify the diversity of nocturnal desaturation. Methods We prospectively enrolled 58 outpatients diagnosed with chronic respiratory disease receiving home oxygen therapy and measured nocturnal SpO2 using a portable oximeter. We classified nocturnal desaturation (3% decrease in SpO2 from baseline) into three patterns: periodic pattern (desaturation duration of <655 seconds), sustained pattern (desaturation duration of ≥655 seconds), and intermittent pattern (desaturation and recovery of SpO2 repeated with a cycle of several minutes). Results Nocturnal hypoxemia (SpO2≤88% for more than 5 minutes) was found in 23.8% of patients. The percentage of patients with chronic obstructive pulmonary disease (COPD) was significantly higher in the nocturnal hypoxemia group than in the non-hypoxemia group (80% vs. 40.6%, p=0.03). Desaturation with a periodic pattern was found in 81% of patients, desaturation with a sustained pattern was found in 40.5% of patients, and desaturation with an intermittent pattern was found in 59.5% of patients. In patients with COPD, desaturation with a periodic pattern was found in 85.7%, desaturation with a sustained pattern was found in 47.6%, and desaturation with an intermittent pattern was found in 57.1%. Conclusion The SpO2 waveform of nocturnal hypoxemia was able to be classified into three patterns. Suitable treatment for each pattern might improve the prognosis of these patients.

Abstract
Background Cisplatin (CDDP) and vinorelbine as an adjuvant chemotherapy improve the overall survival of patients with completely resected non‐small cell lung cancer (NSCLC). However, the treatment completion rate is low due to severe adverse events (AEs). Pemetrexed (PEM) has been used in advanced NSCLC due to its high safety and efficacy. Additionally, the safety of a short hydration method for CDDP administration has been previously reported. Here, we investigated the feasibility of CDDP plus PEM with a short hydration method as adjuvant chemotherapy. Methods A total of 21 completely resected nonsquamous NSCLC patients with pathological stage IIA to IIIA disease were enrolled into the study. Adjuvant chemotherapy consisted of four cycles of CDDP (75 mg/m2) plus PEM (500 mg/m2) every three weeks with a short hydration method. The primary endpoint was the treatment completion rate, and the secondary endpoints included toxicity, the two‐year relapse‐free survival (RFS) rate, and the outpatient treatment rate. Results A total of 21 patients (median age: 66 years; 12 males) were enrolled in two centers. All cases were adenocarcinoma with PS0 (71.4%) or PS1 (28.6%). A total of 81.0% of the patients received four cycles of therapy as scheduled and the primary endpoint was met. The rate of outpatient chemotherapy completion after the second cycle was 90.5%. The grade 3 or higher toxicities were anorexia (n = 2) and pulmonary thromboembolism (n = 1). No grade 3/4 hematological toxicities or creatinine level elevations were observed. The two‐year RFS rate was 57.3%. Conclusions CDDP and PEM with a short hydration is well tolerated in the outpatient setting with limited toxicity. Key points Significant findings of the study CDDP plus PEM adjuvant therapy with a short hydration method is well tolerated in the outpatient setting with limited toxicity. What this study adds CDDP plus PEM with a short hydration method has the potential to be one of the options of adjuvant therapy in the future.

Abstract
AIM The aim of this study was to identify factors affecting the final diagnosis of cough. MATERIALS AND METHODS This study recruited 463 consecutive patients who visited five Japanese general hospitals due to cough from October 2006 to September 2007. Of these, 418 patients (90%) who completed a questionnaire designed to acquire data regarding clinical manifestations of cough were included. RESULTS Most patients with bronchial asthma had cough with seasonal variation and wheezing. Patients with gastro esophageal reflux disease suffered from heartburn and cough without daily or seasonal variation. Cough associated with sinobronchial syndrome was only observed in females and was linked to increased sputum. Patients with whooping cough were bothered by cough interrupting sleep and talking. Patients with cardiogenic cough had exertional dyspnea. CONCLUSION The specific items on our questionnaire relating to patient characteristics, complications, and triggers of cough, represent useful tools for diagnosing the primary disease producing cough.

Abstract
We report the case of a 70-year-old Japanese male diagnosed with advanced lung adenocarcinoma harboring the echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase fusion gene. As soon as crizotinib was administered, tumor shrank immediately. On Day 25, he developed interstitial lung disease. Bronchoalveolar lavage fluid analysis demonstrated elevated lymphocytes fractionation. A drug lymphocyte stimulating test for crizotinib with the bronchoalveolar lavage lymphocytes was negative. Crizotinib administration was discontinued, but a life-threatening flare of tumor growth occurred. Since there was no alternative treatment for the lung cancer, we restarted crizotinib in combination with prednisolone. The patient experienced neither disease progression nor recurrence of interstitial lung disease at 6 months. In cases in which no alternate treatment is known, crizotinib retreatment combined with steroid therapy after crizotinib-induced interstitial lung disease could be considered after a careful consideration of the potential risks and benefits.

Abstract
The aim of this study was to prospectively examine the effect of prophylactic antibiotic use on the development of respiratory infections and on the worsening of symptoms after diagnostic fiberoptic bronchoscopy procedures. This study was an open-label, multicenter, controlled, clinical trial. Patients were alternately assigned to a group given prophylactic antibiotics after bronchoscopy (prophylaxis(+) group) and a group not given antibiotic prophylaxis after bronchoscopy (prophylaxis(-) group), and they were followed-up for 1 week. 158 patients were assigned to the prophylaxis(-) group and 153 to the prophylaxis(+) group. Therapeutic antibiotic administration was needed in 3 patients (1.90%) in the prophylaxis(-) group and 5 patients (3.27%) in the prophylaxis(+) group (risk ratio 1.014, 95% confidence interval 0.978-1.052; p=0.446). Worsening of symptoms after bronchoscopy occurred in 57.6% of all patients by day 7, but no significant differences were observed between the 2 study groups. Prophylactic antibiotic use after bronchoscopy did not prevent the development of infectious events and worsening of symptoms, suggesting that prophylactic antibiotics might not be necessary for routine diagnostic bronchoscopic procedures.

Abstract
Ewing's sarcoma family tumors (ESFT), which include Ewing's sarcoma and primitive neuroectodermal tumors (PNET), have been reported to originate in a variety of sites, mostly in the extremities. Previous reports have shown ESFT originating in the thoracic region, such as chest wall and peripheral lung. We herein report the first case of the ESFT that originated in the main bronchus. Endobronchial snare resection was followed by five courses of chemotherapy (VDC-IE; including vincristine, doxorubicin, cyclophosphamide, ifosfamide and etoposide) and sequential radiation. After the treatment, the patient's condition has improved, and he has remained disease-free for the past year.

Abstract
Graft-versus-host-disease (GVHD) with erythroderma can rarely occur in the context of thymoma and is associated with a poor prognosis due to an increased risk of infection-related death. The present study describes a case of a 50-year-old man with malignant thymoma who developed sepsis in addition to skin manifestations similar to that seen in GVHD. This patient experienced marked improvement in skin lesions in response to steroids and combination chemotherapy with carboplatin and paclitaxel, with subsequent resolution of infection. The present study describes the clinical course of this patient, followed by a review of pertinent reports of thymoma associated with GVHD with particular focus on the efficacy of treatment strategies.

Abstract
Background There have been few reports on the role of Fc receptors (FcRs) and immunoglobulin G (IgG) in asthma. The purpose of this study is to clarify the role of inhibitory FcRs and antigen presenting cells (APCs) in pathogenesis of asthma and to evaluate antigen-transporting and presenting capacity by APCs in the tracheobronchial mucosa. Methods In FcγRIIB deficient (KO) and C57BL/6 (WT) mice, the effects of intratracheal instillation of antigen-specific IgG were analysed using the model with sensitization and airborne challenge with ovalbumin (OVA). Thoracic lymph nodes instilled with fluorescein-conjugated OVA were analysed by fluorescence microscopy. Moreover, we analysed the CD11c+ MHC class II+ cells which intaken fluorescein-conjugated OVA in thoracic lymph nodes by flow cytometry. Also, lung-derived CD11c+ APCs were analysed by flow cytometry. Effects of anti-OVA IgG1 on bone marrow dendritic cells (BMDCs) in vitro were also analysed. Moreover, in FcγRIIB KO mice intravenously transplanted dendritic cells (DCs) differentiated from BMDCs of WT mice, the effects of intratracheal instillation of anti-OVA IgG were evaluated by bronchoalveolar lavage (BAL). Results In WT mice, total cells and eosinophils in BAL fluid reduced after instillation with anti-OVA IgG1. Anti-OVA IgG1 suppressed airway inflammation in hyperresponsiveness and histology. In addition, the number of the fluorescein-conjugated OVA in CD11c+ MHC class II+ cells of thoracic lymph nodes with anti-OVA IgG1 instillation decreased compared with PBS. Also, MHC class II expression on lung-derived CD11c+ APCs with anti-OVA IgG1 instillation reduced. Moreover, in vitro, we showed that BMDCs with anti-OVA IgG1 significantly decreased the T cell proliferation. Finally, we demonstrated that the lacking effects of anti-OVA IgG1 on airway inflammation on FcγRIIB KO mice were restored with WT-derived BMDCs transplanted intravenously. Conclusion Antigen-specific IgG ameliorates allergic airway inflammation via FcγRIIB on DCs.

Abstract
The present study describes a case of a 60-year-old Japanese man who was histologically diagnosed with lung adenocarcinoma harboring L858R mutation of epidermal growth factor receptor. He was successfully treated with gefitinib, but eventually developed leptomeningeal carcinomatosis. He underwent ventriculoperitoneal shunting for hydrocephalus and received erlotinib in place of gefitinib with concurrent whole brain radiotherapy; this resulted in dramatic improvement in his symptoms and performance status from four to one and he survived for as long as 13.6 months after the initiation of erlotinib therapy. This multidisciplinary approach may be particularly useful in terms of increasing survival and improving quality of life.

Abstract
Immunoglobulins (Igs) play important immunomodulatory effects on allergic asthma. Among these, IgG has been reported to regulate allergic inflammation in previous studies about immunotherapy and intravenous immunoglobulin therapy. In this study, to examine the immunomodulatory mechanisms of IgG and FcRs we evaluated the effects of intravenous (i.v.) rabbit IgG administration (IVIgG) on allergic airway inflammation and lung antigen-presenting cells (APCs) in a murine model of ovalbumin (OVA) sensitization and challenge. In OVA-challenged mice, IVIgG attenuated airway eosinophilia, airway hyperresponsiveness and goblet cell hyperplasia and also inhibited the local T helper type (Th) 2 cytokine levels. Additionally, IVIgG attenuated the proliferation of OVA-specific CD4(+) T cells transplanted into OVA-challenged mice. Ex vivo co-culture with OVA-specific CD4(+) cells and lung CD11c(+) APCs from mice with IVIgG revealed the attenuated transcription level of Th2 cytokines, suggesting an inhibitory effect of IVIgG on CD11c(+) APCs to induce Th2 response. Next, to analyse the effects on Fcγ receptor IIb and dendritic cells (DCs), asthmatic features in Fcγ receptor IIb-deficient mice were analysed. IVIgG failed to attenuate airway eosinophilia, airway inflammation and goblet cell hyperplasia. However, the lacking effects of IVIgG on airway eosinophilia in Fcγ receptor IIb deficiency were restored by i.v. transplantation of wild-type bone marrow-derived CD11c(+) DCs. These results demonstrate that IVIgG attenuates asthmatic features and the function of lung CD11c(+) DCs via Fcγ receptor IIb in allergic airway inflammation. Targeting Fc portions of IgG and Fcγ receptor IIb on CD11c(+) DCs in allergic asthma is a promising therapeutic strategy.

Abstract
Asthma is a chronic inflammatory airway disease characterized by airway hyperreactivity, increased mucus production, and reversible airway contraction. Asthma is a complex genetic trait caused by environmental factors in genetically predisposed individuals. The transportation of maternal antigen-specific IgG via amniotic fluid, placenta and breast milk plays an important role in passive immunity. First, to examine whether maternal passive immunity by the transportation of antigen-specific IgG via FcRn regulates allergic airway inflammation, ovalbumin-immunized FcRn(+/-) female mice were bred with FcRn(-/-) male mice to evaluate the degree of ovalbumin-induced allergic airway inflammation of FcRn(-/-) offspring. Maternal passive immunity regulated allergic airway inflammation in an FcRn-dependent manner. Second, to examine the role of maternal antigen-specific IgG1 injection into mothers, we intravenously injected ovalbumin-specific IgG1 into wild-type or FcRn(+/-) mice immediately after they gave birth. The offspring were sensitized and challenged with ovalbumin. Antigen-specific IgG1 administered to lactating mice reduced allergic airway inflammation in their offspring in an FcRn-dependent manner. Last, to exclude the factor of maternal passive immunity other than ovalbumin-specific IgG1, we administered ovalbumin-specific IgG1 orally to offspring after birth. Oral administration of ovalbumin-specific IgG1 to offspring during the lactating period prevented the development of allergic airway inflammation in an FcRn-dependent manner. These data show that the transfer of maternal antigen-specific IgG regulates the development of allergic airway inflammation early in life in an FcRn-dependent manner.

Abstract
Our previous report showed that inhibition of sphingosine kinase (SphK) ameliorates eosinophilic inflammation and mucin production in a mouse asthmatic model. To clarify the role of SphK in airway mucin production, we utilized the mouse asthmatic model and found that both SphK and MUC5AC expression were increased and co-localized in airway epithelium. Next we cultured normal human bronchial epithelial cells in an air-liquid interface and treated with IL-13 to induce their differentiation into goblet cells. We found that SphK1 and MUC5AC expression was increased by IL-13 treatment at both protein and mRNA levels, whereas SphK2 expression was not changed. N,N-dimethylsphingosine (DMS), a potent SphK inhibitor, decreased MUC5AC expression up-regulated by IL-13 treatment. Furthermore, DMS inhibited IL-13-induced ERK1/2 phosphorylation but neither p38 MAPK nor STAT6 phosphorylation. These results suggest that SphK1 is involved in MUC5AC production induced by IL-13 upstream of ERK1/2 phosphorylation, and independent of STAT6 phosphorylation.

Abstract
The airway remodeling that occurs in asthma is characterized by an excess of extracellular matrix deposition in the submucosa, hyperplasia/hypertrophy of smooth muscle, goblet cell metaplasia, and accumulation of fibroblasts/myofibroblasts. The urokinase-type plasminogen activator (uPA)/plasmin system participates in pericellular proteolysis and is capable of directly degrading matrix components, activating latent proteinases, and activating growth factors. In a mouse ovalbumin (OVA) asthma model, we increased plasminogen activator activity in the lung by administering exogenous uPA or by using mice genetically deficient in the uPA inhibitor plasminogen activator inhibitor-1 (PAI-1) to assess the role of this system in asthma pathogenesis. After intraperitoneal OVA sensitization, mice inhaled OVA plus uPA (500 IU/mouse) or saline by ultrasonic nebulization for 3 wk. When studied 24 h after the final exposure, the groups with upregulated plasmin activity had significantly reduced subepithelial fibrosis within the airway walls and had decreased airway hyperresponsiveness (AHR) to methacholine. Morphometric analysis showed that subepithelial wall thickening of the bronchi (subepithelial area ratio) was also reduced, as were collagen and alpha-smooth muscle actin. Upregulation of plasmin activity also increased the level of hepatocyte growth factor activity in bronchoalveolar lavage fluid, whereas the release of transforming growth factor-beta was decreased. The administration of uPA 1 wk after the last OVA inhalation also significantly reduced lung hydroxyproline content and AHR. These results show that enhancing uPA/plasmin activity lessens the airway remodeling in a murine asthma model.

Abstract
A 67-year-old woman presented with a pleural effusion and a tumor in the right pleural wall. Histological examination of thoracoscopic tumor and pleural biopsy specimens showed infiltration by medium sized cells, some of which showed plasmacytoid differentiation. In view of the presence of IgM paraproteinemia and bone marrow involvement by lymphoma cells, the patient was diagnosed tentatively as having lymphoplasmacytic lymphoma (LPL). However, chromosomal analysis of the cells in the pleural fluid detected t(14;18)(q32;q21), while fluorescence in situ hybridization was positive for 11% of the MALT1 split signal. Because of the presence of characteristic genetic abnormalities and notable extranodal involvement, the patient was diagnosed as having MALT lymphoma. She was treated with three courses of cladribine and rituximab, and achieved complete regression of the tumor. In this case the detection of t(14;18)(q32;q21) involving IGH and MALT1 was useful for the differential diagnosis of LPL and MALT lymphoma.

This study aimed to identify predictive factors associated with prognostic benefits of gefitinib.

Overall response rate (ORR) was 24.4% and median survival time (MST) was 8.0 months. In a log-rank test, survival was significantly better in females, patients with adenocarcinoma, never-smokers, favourable performance status (PS) and patients with epidermal growth factor receptor (EGFR) mutation. The lower the smoking exposure (Brinkman Index (BI)=cigarettes per day x years smoked), the better the MST (BI 0: 14.5 months, BI <500: 9.5 months, BI 500 to <1000: 6.9 months, BI > or =1000: 4.0 months). Positive-EGFR mutation status and PS 0-1 were independent predictors of favourable prognosis by multivariate analysis. Prognosis was significantly different according to EGFR mutation status (with the same smoking status), but not according to smoking status (with the same EGFR mutation status). EGFR mutation status is the most important independent predictor of survival benefit with gefitinib treatment. Although differences in prognosis were observed according to relative smoking status and smoking exposure, the results suggested that smoking is not a direct predictor of prognosis, yet is a surrogate marker of EGFR mutation status.

Abstract
17020 Background: Gefitinib, an inhibitor of epidermal growth factor receptor (EGFR) tyrosine kinase, has shown meaningful antitumor activity for advanced NSCLC. Survival benefit of treatment with gefitinib has not been shown in unselected patients, however heterogeneity in survival outcomes between sub-group (histological types, gender, smoking status and ethnicity) of patients has been observed. The aim of this study was to identify the potential predictive features associated with the survival benefit of treatment with gefitinib. Methods: All NSCLC patients who began taking gefitinib during the period from July 2002 until July 2005 in our institute were retrospectively reviewed. Potential factors analyzed included age, gender, smoking history, performance status (PS), histology, stage, and prior chemotherapy. Results: Overall 221 patients were analyzed. The overall response rate of gefitinib was 26.7%. Median survival time (MST) was 8.0 months. MST of patients whose tumor response was partial response (PR) was 34.5 months. Univariate analysis revealed that the predictive factors of favorable survival were female (p = 0.001), never-smoker (p < 0.0001), good PS (p < 0.0001) and adenocarcinoma (p < 0.0001). Multivariate analysis showed that never-smoking history (p = 0.005), adenocarcinoma (p = 0.004), and better PS (P < 0.001) were significant independent predictors of long survival. The Brinkman index (BI), number of cigarettes per day multiplied by number of years smoked, was associated with survival benefit. MST was 17.6 months in the BI = 0 group (never-smokers), 9.7 months in 1 ≤BI <500, 6.9 months in 500 ≤BI <1000, 4.4 months in 1000 ≤BI <1500, and 4.0 months in BI ≥1500. Conclusion: Never-smokers and adenocarcinoma are predictive factors for prolonged survival. As for smoking status, lower BI is associated with better prognosis after treatment with gefitinib. Therefore, histological factors and smoking status must be considered when treating with gefitinib. No significant financial relationships to disclose.

Abstract
BACKGROUND Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for atherosclerosis. CD40-CD40 ligand interaction promotes several proinflammatory mediators and plays a pivotal role in the various stages of atherosclerotic diseases. The present study examines whether CD40 ligation contributes to outcomes in patients with OSAS. METHODS The study population comprised OSAS patients with an apnea hypopnea index (AHI) > or = 30 (n = 35) and control subjects (AHI < 5; n = 16). We measured serum levels of soluble CD40 ligand (sCD40L), tumor necrosis factor (TNF)-alpha, and hypersensitive C-reactive protein (hsCRP) before and after nasal continuous positive airway pressure (nCPAP) therapy for 3 months. RESULTS Baseline levels of sCD40L were significantly higher in patients with OSAS (6.93 +/- 4.64 ng/mL) [mean +/- SD] than in control subjects (3.43 +/- 2.11 ng/mL, p < 0.01). Baseline levels of sCD40L positively correlated with TNF-alpha but not with hsCRP. The elevation of sCD40L was improved for 1 night after nCPAP therapy (3.83 +/- 2.78 ng/mL, p < 0.001). Even though patients with severe OSAS did not receive any other medication to control atherosclerotic risk factors for 3 months, nCPAP was continued to reduce the levels of sCD40L. CONCLUSION The present study suggested that sCD40L is a key factor that links OSAS and atherosclerotic progression.

Abstract
BACKGROUND Some patients develop asthmatic symptoms such as wheezing and dyspnea during the course of cough variant asthma (CVA), which are considered precursors of classical asthma. OBJECTIVES To identify the characteristics of such patients, we investigated the nature of CVA patients with or without developing bronchial asthma in the longitudinal study. METHODS In 28 CVA patients whom we could observe over 5 years, duration of coughing, physical examination findings, pulmonary function and bronchial hyperresponsiveness to inhaled methacholine were retrospectively assessed. RESULTS Of these patients with CVA, 10 developed the asthmatic symptoms of wheezing and dyspnea (precursors of classical asthma) over 5 years. All these 10 patients showed marked bronchial hyperresponsiveness; however, there were no significant differences in the bronchial responsiveness to methacholine between patients with precursors of classical asthma and pure CVA patients who did not wheeze. The duration of coughing had a significant relationship with precursors of classical asthma. Seven patients with precursors of classical asthma developed wheezing in the first year and 1 patient each in the second, third and fourth year. CONCLUSIONS These findings of a 5-year observation suggest that longer duration of coughing may be an important factor that develops precursors of classical asthma in patients with CVA.

Abstract
A 64-year-old man was admitted to our hospital complaining of dyspnea and fever. He had been treated with low-dose methotrexate for rheumatoid arthritis. Chest radiography showed diffuse ground-glass attenuation in both lung fields, and hypoxia was detected. Pneumosystis carinii pneumonia was demonstrated on transbronchial lung biopsy, and the serum beta-D glucan level was high. We started treatment with trimethoprim-sulphamethoxazole, but respiratory failure worsened, and drug-induced pancytopenia occurred. Although trimethoprim-sulphamethoxazole was stopped, pancytopenia persisted and the patient required ventilatory support. After we changed the medication from trimethoprim-sulphamethoxazole to pentamidine, respiratory failure improved. It was thought that pneumocystis carinii pneumonia was associated with low-dose methotrexate and that trimethoprim-sulphamethoxazole interacted with methotrexate to induce severe pancytopenia.

Abstract
Airway remodeling is one of the most important features of bronchial asthma. However, there are few studies that have used repeated antigen exposure in murine models. We designed a murine chronic antigen exposure model necessary for studying airway remodeling. Two different strains of mice, BALB/c mice and C57BL/6 mice, were sensitized and challenged for 3-7 weeks with ovalbumin (OVA). Bronchoalveolar lavage (BAL) and histology study were conducted in each phase. Morphometry was performed, and the epithelial area ratio (Ae ratio) and subepithelial area ratio (As ratio) were calculated. The Ae ratio and As ratio of BALB/c mice were significantly increased in sensitized mice compared with non-sensitized mice at 3 and 5 weeks, but not at 7 weeks. In C57BL/6 mice, the Ae ratio showed no significant changes, whereas the As ratio maintained high from 3 to 7 weeks. This thickening of the subepithelial layer consisted of collagen fibers with elastica van-Gieson (EVG) stain. Lymphocytes of the BAL showed a significant increase at 3 and 7 weeks in C57BL/6 mice, but not in BALB/c mice. A murine chronic OVA exposure model in C57BL/6 mice revealed subepithelial layer thickening consisting of collagen fibers and increased lymphocytes until 7 weeks. C57BL/6 mice are useful to elucidate the mechanism of airway remodeling.

Abstract
Klotho mice, which exhibit multiple phenotypes resembling human aging, develop pulmonary emphysema. In this study, to clarify the mechanism of their emphysematous change through development, we evaluated the expression of matrix metalloproteinase (MMP)-2, 9 and the tissue inhibitors of matrix metalloproteinase (TIMP)-1, 2 in the lungs of Klotho mice and wild type mice. Klotho mice showed obvious air space enlargement at 5 weeks of age, but not at 2 weeks of age. Immunohistochemical analysis revealed that expression of MMP-9 was increased in Klotho mice compared with wild type at 5 weeks of age. Western blot analysis and gelatin zymography also revealed that the expression and the gelatinolytic activity of MMP-9 were increased in the lungs of Klotho mice. The expression of TIMP-1 decreased in the lungs of Klotho mice. MMP-2 and TIMP-2 showed no significant differences at 5 weeks of age. At 2 weeks of age, there were no significant differences in the expressions of MMP-9 and TIMP-1 between Klotho and wild type mice. These findings suggest that imbalance of MMP-9 and TIMP-1 is associated with the development of pulmonary emphysema in Klotho mice.

Abstract
A 66-year-old man was admitted to our hospital because of progressive dyspnea on effort. Arterial blood gas analysis showed severe hypoxemia, and a chest radiograph revealed reticular shadows in both lower lungs and an increase of the cardiothoracic ratio. Echocardiography demonstrated mild indentation of the interventricular septum toward the left ventricle, moderate pericardial effusion and pulmonary hypertension. From these data, we diagnosed pulmonary thromboembolism and started anticoagulation therapy. After the addition of the administration of warfarin and oxygen therapy, his symptoms disappeared. However, we could not obtain more supporting evidence of thromboembolization by methods of ventilation-perfusion scanning, digital subtraction angiography of the pulmonary artery, or venography. Blood coagulation analysis demonstrated that the patient's plasma protein C antigen levels and its activity were depleted. The patient's son had a history of thrombophlebitis and pulmonary embolization, and his data of protein C antigen levels was also decreased. Therefore, this patient was found to have a character of familial protein C deficiency type I. We could not get the conclusive proof of pulmonary thromboembolism, but we considered that the presence of familial protein C deficiency may cause exacerbation of pulmonary hypertension.

Abstract
BAG-1 is a recently identified Bcl-2-interacting anti-apoptotic protein. The aim of our study was to investigate the immunohistochemical staining pattern of BAG-1 protein in patients with colorectal cancer and examine associations of BAG-1 expression with various clinicopathological factors and patient survival. Tumour samples were collected from 86 patients diagnosed with colorectal cancer. There was significant variation in the immunohistochemical staining patterns for BAG-1, including absent staining and staining of either the cytoplasm, nucleus or both. Twenty-one colorectal carcinomas (24.4%) exhibited a nuclear staining pattern whilst 56 (65.1%) exhibited cytoplasmic staining. The percentage of cases exhibiting nuclear BAG-1 positivity was significantly higher in distant metastasis-positive cases (55.6%) than in distant metastasis-negative cases (20.8%; P=0.036). Overall survival was significantly shorter for patients with tumours exhibiting BAG-1 positive nuclei than those with absent nuclear BAG-1-staining (P=0.011). In addition, the multivariate cox proportional hazard models indicated that nuclear BAG-1 expression was the only independent prognostic variable for mortality (P=0.013). These studies demonstrate that nuclear BAG-1 expression is a useful predictive factor for distant metastasis and a poor prognosis in patients with colorectal cancer.

Abstract
A 41-year-old man fell into type II respiratory failure after catching a cold, and became dependent on a respirator. Chest radiography showed no abnormalities and the hyperventilation test showed improved arterial blood gas findings. His sleep study showed marked nocturnal desaturation due to hypopnea and apnea with a decrease of thoracic and abdominal movement during sleep. Therefore, we diagnosed him as primary alveolar hypoventilation syndrome (PAH). Seven years previously, his 2-year elder sister had suffered from similar respiratory failure during her second pregnancy and had been diagnosed as PAH. While myopathy was suspected in both cases, attenuation of muscle strength was slight and it appeared not to be the main cause of alveolar hypoventilation. Since medication was not effective in each case, they underwent non-invasive positive pressure ventilation (NIPPV). While sustained mild hypercapnia remained during the daytime, it improved their respiratory failure. To our knowledge, this is the first study of familial adult onset PAH.

Abstract
A 70-year-old woman was admitted in April 1997 because a coin lesion in the left middle lung field was observed on chest roentgenograms. The lesion had slightly increased in size since 1994, when it was first pointed out. Chest computed tomography elucidated a high density area with irregular borders in the center of the shadow in S 3 a. Transbronchial biopsy revealed adenocarcinoma, and a left upper lobectomy was performed. The resected specimen demonstrated a tumor with central ossification and pleural indentation. Histologic examination determined that the the tumor was a papillary adenocarcinoma with central ossification containing marrow tissue. Primary lung cancer with central ossification is very rare, and only 6 cases have been reported to date, including this case.

Abstract
The clinical case is 68 year old woman. The patient experienced dyspnea and back pain. Chest X-ray and CT showed a large well-defined mass from the left thorax expanding to the right. The tumor, which was derived from the left lobe of thymus, was removed. Cut surface of the resected tumor showed multilobar patterns and a yellow-white portion like a wedge in a part of the tumor. Histological examinations revealed that the multilobar portion was thymic carcinoid and a yellow-white portion was malignant fibrous histiocytoma. As far as we examined, literature pertaining to such double cancers has never been reported.
