Tracheobronchial disruption is an uncommon injury associated with blunt chest trauma. We report CT features and pathologic findings of two pediatric cases in which a bronchial injury was unnoticed initially but was diagnosed later by appearance of delayed bronchostenosis with distal atelectasis after blunt chest trauma in recent motor vehicle accidents. Pathologically, obliteration of the bronc...

We describe the case of an intrabronchial aspirated foreign body that caused a persistent right lower lobe infiltrate. A first fibreoptic bronchoscopy demonstrated a mass with tumour-like appearance in the right bronchus intermedias, but the bronchial biopsies and the cytological smears of the bronchial aspirate failed to reveal any malignancy. During a control fibreoptic bronchoscopy, we found...

This study examines the possibility that products of neutrophils and eosinophils could increase the responsiveness of human isolated bronchial tissue. Neutrophils and eosinophils were isolated from the peripheral blood of healthy volunteers. The cells were incubated with 1 microM calcium ionophore A23187 for 10-15 min then centrifuged, the supernatant collected and stored at -70 degrees C. Huma...

Interest in the biological roles of cell membrane-derived vesicles in cell-cell communication has increased in recent years. Microparticles (MPs) are one such type of vesicles, ranging in diameter from 0.1 μm to 1 μm, and typically shed from the plasma membrane of eukaryotic cells undergoing activation or apoptosis. Here we describe the generation of T lymphocyte-derived microparticles (LMPs) f...

Gastric mucosal damage by iron pills is often reported. However, iron pill aspiration is uncommon. Oxidation of the impacted iron pill causes bronchial mucosal damage that progresses to chronic bronchial inflammation, necrosis, endobronchial stenosis and rarely, perforation. We reported a case of a 92-year-old woman with chronic productive cough and significant left-sided atelectasis. Bronchosc...

It has recently been suggested that RhoA plays an important role in the enhancement of Ca2+ sensitization observed in smooth muscle contraction. In the present study, the expression of rhoA mRNA in the bronchial smooth muscle of antigen-induced airway hyperresponsive rats was compared with that of control animals. Reverse transcription-polymerase chain reaction experiments using total RNA from ...

The hypertrophy of the bronchial arteries in bronchiectasis has been known to surgeons ever since resection of the lung had been practised for this condition. Histologists have noticed and commented upon the extreme vascularity of the tissue round the bronchiectatic sacs, and have tried to explain this as part of the general inflammatory change. The physiological importance and significance of ...

The concentrations of two antibiotics, amoxycillin and ciprofloxacin, were measured by microbiological assay in serum and in bronchial mucosa obtained at fibreoptic bronchoscopy in 38 patients undergoing diagnostic bronchoscopy for a range of respiratory symptoms. Patients had taken one of the two drugs orally for four days before bronchoscopy. The percentage penetration of antibiotic from seru...

introdution: tuberculosis (tb), with different types of respiratory tract involvements, has a high rate of mortality all around the world. endobronchial involvement, which is a slightly common tuberculous infection, requires special attention due to its severe complications such as bronchostenosis. aim of study of this study was describes, one type of pulmonary tuberculosis with less diagnosed ...
