The purpose of this paper is to describe a standardized bronchoalveolar lavage (BAL) technique used in 11 clinically healthy foals from one week of age to2 months of age. All foals successfully underwent this procedure five times at different ages. This technique was performed under intravenous general anesthesia with no apparent complications. In our experience, performing transendoscopic BAL ...

Researchers over the past 40 years have utilized bronchoalveolar lavage (BAL) as a tool to help expand our knowledge of pulmonary medicine. Many reports have documented BAL as a safe procedure for research subjects. New technologies, such as flow cytometry, have provided much needed insight into the mechanisms behind several pulmonary diseases. The concept of the lung as an easily accessible mu...

Industrial fibrous dusts are applied in many industrial branches and represent adverse factors in occupational and environmental area. Refractory ceramic fibers (RCFs) - amorphous alumina silicates - are used as one kind of asbestos substitutes. Because RCFs are relatively durable and some RCFs are respirable, they may present a potential health hazard by inhalation. The aim of present work was...

The differences in specificity of human lung and peripheral lymphocytes for mycobacterial antigens (Ag) need to be evaluated in order to identify vaccine candidates against pulmonary tuberculosis (TB). Therefore, the present study examined the response to low molecular weight secretory proteins of Mycobacterium tuberculosis in bronchoalveolar lavage (BAL) and peripheral blood mononuclear cells ...

This study examines the value of bronchoalveolar lavage (BAL) in diagnosing lymphangitic carcinomatosis. A retrospective analysis of fiberoptic bronchoscopic records at a tertiary referral hospital was performed. Twelve patients with neoplastic disease and diffuse pulmonary infiltrates compatible with lymphangitic carcinomatosis who underwent diagnostic fiberoptic bronchoscopy were identified. ...

The aim of this study was to assess the diagnostic efficacy Xpert MTB/RIF assay in bronchoalveolar lavage (BAL) diagnosis pulmonary tuberculosis sputum-smear negative patients. This observational case series conducted a tertiary base institute Bangladesh from July 2017 June 2019. All patients with suspected who were negative, irrespective age and gender included study. BAL fluid thus obtained e...

BACKGROUND Inhalation of swine dust causes airway inflammation with influx of inflammatory cells, predominantly neutrophils, into the lungs. A study was undertaken to determine whether or not exposure to swine dust induces release of interleukin 8 (IL-8) into upper and lower airways and how this possible release is related to cellular influx. A further aim was to study the relationship between ...

Oxidative stress in acute respiratory distress syndrome (ARDS) is considered as an important pathophysiological mechanism in acute impairment of lung function. The present study investigated whether a pulmonary oxidant-antioxidant imbalance is indicated by substantial oxidative modification of proteins in bronchoalveolar lavage (BAL) fluid. Oxidatively modified proteins in BAL fluid, as measure...

A study was conducted with transmission electron microscopy to find whether bronchoalveolar lavage could be used to identify subjects with occupational exposure to mineral particles. Non-fibrous mineral particles in bronchoalveolar lavage (BAL) fluid from 46 dental technicians and 41 white collar controls with lung diseases but free from occupational exposure to dusts were analysed. The total p...

During advanced AIDS tuberculosis (TB) often presents atypically with smear-negative and non-cavitary disease, yet immune features associated with this change are poorly characterized. We examined the local immune response in a cohort of Tanzanian AIDS-associated TB patients who underwent bronchoalveolar lavage. TB infection was confirmed in bronchoalveolar lavage (BAL) fluid by culture, probe ...
