The aim of this study was to determine the relative production of chemokines interleukin-8 (IL-8), regulated on activation, normal T-cell expressed and secreted (RANTES) and monocyte chemotactic protein-1 (MCP-1) by intrinsic and extrinsic asthmatics. Nine intrinsic asthmatics, 10 extrinsic asthmatics, five nonatopic and five atopic controls underwent bronchoalveolar lavage (BAL). Total BAL cel...

from january 1982 to april 1987 , 1500 cases of fiberoptic bronchoscopy (fob) were performed. among these cases, 37 were suspected of having pulmonary tuberculosis but their sputum examination was either negative or they were not able to expectorate. in all these cases pulmonary tb was confirmed either by bronchoalveolar lavage (bal) fluid examination or by biopsy. we conclude that fob is a val...

Bronchoscopy with bronchoalveolar lavage (BAL) is an important research tool for assessing airway inflammation in a variety of inflammatory lung diseases. In chronic obstructive pulmonary disease (COPD), BAL recovery is often low, making analysis of the recovered fluid difficult to interpret. The present authors hypothesised that the degree of emphysema may predict BAL recovery. A total of 20 C...

Background: The prevalence of lung cancer has shown an increase over the last few years which cause both health and economic burden. biopsy is gold standard tool for disease diagnosis, but it usually not accepted by patients due to its invasive nature. use non-invasive biomarkers now attaining a great interest in diagnosis. Aim work: Assess role Annexin A1 bronchoalveolar lavage serum early dia...

Candida spp. it has been possessed of different virulence and resistance patterns in each species, C. albicans remains the main pathogen infected hosts, but non-albicans also tries with infection. This study aimed to identify species bronchoalveolar lavage fluid (BAL) sample patients lower respiratory infections method multiplex PCR (Polymerase Chain Reaction). was a descriptive analytical cros...

based on our knowledge, there have been no studies about the effect of age, sex, lobe and slaughtering stress on cellular distribution of bronchoalveolar lavage fluids in calves and cattle in iran. objectives: the main purpose of this study was to compare the cell distribution pattern of bronchial alveolar lavage fluids in calves and cattle in terms of age, sex, type of lung lobes and the stres...

The antioxidant glutathione (GSH) is increased in the epithelial lining fluid (ELF) of chronic smokers. The rate-limiting enzyme in GSH synthesis is glutamate-cysteine ligase (GCL), also known as gamma-glutamylcysteine synthetase, consisting of a heavy, catalytic (GCLC) and a light, modulatory (GCLM) subunit. To determine the contribution of bronchoalveolar lavage (BAL) cells to GSH levels in E...

Neutrophil-dominated endobronchial inflammation is a major characteristic of cystic fibrosis (CF) and there is increasing demand for easy-to-perform noninvasive monitoring for prediction and intervention. Fourteen stable paediatric CF patients (8-17 yrs; mean forced expiratory volume in one second 86.7% of the predicted value) were investigated once by fractional bronchoalveolar lavage (BAL) an...
