The effects of exogenous and endogenous granulocyte colony-stimulating factor (G-CSF) on invasion by cancer cells were studied, using lung cancer cell lines that produce G-CSF (NCI-H157) and lines that do not (PC-9 and NCI-H23). The invasive capacity of NCI-H157 cells was 26- to 27-fold higher than that of PC-9 and NCI-H23 cells. The invasiveness of PC-9(More)
BACKGROUND AND OBJECTIVE The usefulness of two tests in the serodiagnosis of chronic pulmonary aspergillosis (CPA) was compared. The tests were the serum Aspergillus galactomannan antigen test (Platelia (R) Aspergillus) by enzyme-linked immunoassay (EIA) using old and new cut-off indexes, and the Aspergillus precipitating antibody test. METHODS Both(More)
BACKGROUND Nursing and healthcare-associated pneumonia (NHCAP) is a relatively new condition that was recently defined by the Japanese Respiratory Society. Previous reports and guidelines have not thoroughly investigated the adverse prognostic factors and validity of the selection criteria for NHCAP. The purpose of this research was to clarify the adverse(More)
We reported previously that granulocyte colony-stimulating factor (G-CSF) can promote the invasion ofhuman lung cancer cell lines in vitro. However, the exact mechanism of its stimulatory effect on invasionremains to be elucidated. In the present study we mainly focused our attention on the components of theplasminogen activation system in human lung cancer(More)
OBJECTIVE Streptococcus pneumoniae is an important and common pathogen of acute pneumonia. The urinary pneumococcal antigen test has been increasingly used for the diagnosis of pneumococcal pneumonia, but there have been few studies on pneumococcal pneumonia after this test became prevalent. The present study was conducted to characterize the clinical(More)
Concurrent chemoradiotherapy for regionally advanced stage III non-small cell lung cancer is the standard treatment method. However, the clinical implications of consolidation chemotherapy following chemoradiation have been unclear. Therefore, we conducted a phase II study of concurrent weekly carboplatin plus paclitaxel treatment in combination with(More)
Although drug-induced interstitial pneumonitis caused by gefitinib is well recognized in Japan, reports of alveolar hemorrhage caused by gefitinib are very rare. We encountered a case of alveolar hemorrhage thought to be caused by gefitinib. A 74-year-old woman with non-small cell lung cancer (adenocarcinoma; cT4NOM0, stage IIIB) had been receiving(More)
A 60-year-old man was admitted to our hospital with fever, appetite loss, and fatigue. Chest X-ray films and computed tomography scans showed fungus-ball-like lesions in the thoracic cavity, and pleural thickening with surrounding infiltration in the left upper lobe, developing over several months. The white blood cell count (WBC) and serum C-reactive(More)
Group C adenovirus is latent in human tissues and can malignantly transform cells. The purpose of this study was to investigate the association between this virus and lung cancer. We investigated latent adenoviral infection using the nested polymerase chain reaction and in situ hybridization in transbronchial biopsy specimens from patients with small-cell(More)
One of the printing troubles on print quality is non-uniformity of printing density called print mottle. The causes of print mottle are various. As far as paper, it has been thought that surface roughness of paper, absorption of ink and fountain solution cause non-uniformity of ink transfer. As the results of evaluation on commercial coated paper, print(More)
