A cytogenetic analysis was performed on direct preparations and short-term cell cultures of lung tumor and normal bronchial epithelium of 19 patients carrying either a first or a second primary lung cancer. In 9 tumors (6 squamous cell carcinomas, 1 adenocarcinoma, 1 mucoepidermoid carcinoma, and 1 small cell lung carcinoma) successfully analyzed, pseudodiploid and hyperdiploid karyotypes were ...
BACKGROUND For years, the analysis of innate responses to the major mold pathogen Aspergillus fumigatus has been restricted to specialized cells, such as professional phagocytes. More recently, the contribution of the airway epithelial barrier has been assessed and studies have shown that it was able to sense and react to the Aspergillus infection, for example, by producing cytokines. METHODS...
Objectives To evaluate the radiographic lung pattern and topographical distribution in canine eosinophilic bronchopneumopathy. Materials Methods Medical records were retrospectively reviewed for dogs diagnosed with Lateral thoracic radiographs examined presence of increased radiopacity, classification pattern, topography changes (cranioventral, perihilar, caudodorsal, caudoventral) severity pul...
As minute volume increases with age, a study was carried out to determine whether the measurement of bronchial responsiveness to pharmacological agents with the tidal breathing technique in children might be influenced by age. Bronchial responsiveness to histamine administered by tidal breathing was therefore compared with that produced with a dosimeter in 25 children with asthma aged 5-18 year...
Lung branching morphogenesis has been studied for decades, but the underlying developmental mechanisms are still not fully understood. Cellular movements dynamically change during the branching process, but it is difficult to observe long-term cellular dynamics by in vivo or tissue culture experiments. Therefore, developing an in vitro experimental model of bronchial tree would provide an essen...
Spontaneous Crenosoma vulpis infection in 10 dogs: laboratory, radiographic and endoscopic findings.
Crenosoma (C.) vulpis infection was diagnosed in 10 dogs aged between 0.5 and 12 years (median 4 years) during a 4-year period. The predominant clinical sign in all dogs was coughing which lasted from 1 day to > 4 months. Hematological abnormalities included eosinophilia in 5/9 dogs, basophilia in 3/9 dogs, and mild monocytosis in 6/9 dogs. Thoracic radiographs (n = 9) were normal in 1 dog, sho...
We investigated determinants of change in bronchial reactivity in the Swiss Cohort Study on Air Pollution and Lung Diseases in Adults (SAPALDIA), a population-based cohort with wide age range (29-72 yrs at follow-up). The role of sex, age, atopic status, smoking and body mass index (BMI) on percentage change in bronchial reactivity slope from the baseline value was analysed in 3,005 participant...
OBJECTIVE The early diagnosis of chronic organ rejection after lung transplantation (LTx) is currently hampered by the lack of reliable diagnostic markers. The present study aims to establish the procedure of gene expression profiling in bronchial epithelial cells for the identification of candidate genes that might prove useful in the early diagnosis. METHODS Twenty-three patients who underw...
Objectives- to provide a reference anatomy of the bronchial tree of the Jebeer Gazelle by using computed tomographic modality. Design- Experimental study. Animals- Three female Jebeer Gazelle Procedures- Spiral CT images were taken from the thoracic region perpendicular to long axis of the body. CT windows were adjusted as necessary to have optimized images of pulmonary organ. The images ...
OBJECTIVE To evaluate the primary drug resistance of new culture positive cases of pulmonary tuberculosis in Karachi. METHODS All new suspected pulmonary tuberculosis patients were recruited initially. They were instructed to produce three-sputum samples for smear examination and on one of the specimen's culture was applied. Bronchoscopy and bronchial wash was done in patients who were not ex...
