INTRODUCTION Distal airway secretions can be sampled by bronchoscopic bronchoalveolar lavage (B-BAL), blind protected BAL (BP-BAL), and tracheal aspiration (TA). We quantitatively compared the cultures of distal airway secretions from BP-BAL, B-BAL, and TA specimens, and assessed the efficacy of the three above methods in diagnosing bronchitis in tracheostomized children. METHODS Twenty child...

BAL QSOs are notoriously faint X-ray sources, presumably due to extreme intrinsic absorption. However, several objects have begun to appear through the obscuration with recent X-ray observations by Chandra and ASCA. Where enough counts are present for X-ray spectroscopy, the signatures of absorption are clear. The evidence is also mounting that the absorbers are more complicated than previous s...

results in total, 261 patients (119 sarcoidosis and 142 non-sarcoidosis ilds) were enrolled. the median (interquartile range) bal cd4/cd8 ratio and lymphocyte fraction were significantly higher in sarcoidosis than in non-sarcoidosis ilds: 3.88 (3.76) versus 0.88 (1.01), respectively, and 20.6 (28.3) versus 6.0 (13.7), respectively. t cell receptor γ delta, cd16+56+, cd103+, cd8+103+, and cd3+16...

Bu çalışmada, bal arısı kovanı ürünlerinden olan bal, arı ekmeği, poleni ve erkek larvası (apilarnil)'in toplam fenolik (TPC) flavonoid (TFC) profilleri ortaya konuldu. Bunun yanı sıra söz konusu örneklerin antioksidan aktiviteleri, 2,2′-azinobis (3-ethylbenzothiazolin)-6-sulfphonate (ABTS) assay ferric reducing antioxidant power (FRAP) 1,1-diphenyl-2-picrylhydrazy (DPPH) metotları kullanılarak...

objective: among the members of legionellaceae, legionella pneumophila is involved in 95% of cases of severe pneumonia. isolation of the causative agent from bronchoalveolar lavage (bal) fluid specimen is a delicate process and also time-consuming. moreover, it has been shown that some legionella strains may be viable but cannot be cultured. the aim of this study was comparison of culture and p...

BACKGROUND Markers of ventilator associated pneumonia are of interest for confirming the diagnosis and for guiding the initial management of this frequent complication of mechanical ventilation. The detection of intracellular organisms in the polymorphonuclear leucocytes (PMNLs) and/or macrophages of bronchoalveolar lavage (BAL) fluid has been suggested as a specific test for the early indicati...

Specimens from sputum induction (SI) are often of insufficient volume or have poor diagnostic yield for the diagnosis of Pneumocystis carinii pneumonia (PCP). The Ballard catheter for bronchoalveolar lavage (BAL) is a disposable BAL device which is passed transnasally into the airway and wedged by sensation. Thirty consecutive episodes (21 inpatient and 9 outpatient) in 28 patients positive for...

The sensitivity of all fiberoptic bronchoscopic techniques in case of a peripheral lung cancer is 69%. In the study, it was aimed to assess the contribution of broncoalveolar lavage (BAL) performed before and after standard biopsy procedures in the diagnosis of peripheral lung cancer. The patients with peripheral lung lesion in radiology, and normal bronchoscopic findings were included in the s...
