Mycobacterium tuberculosis is a serious, but rare infectious complication after allogeneic bone marrow transplantation. Tuberculosis is a major problem in South East Asia, particularly in India and Pakistan. We describe here infection due to mycobacterium tuberculosis in four patients after allogeneic stem cell transplantation (Allo SCT). The diagnosis was made on the bases of clinical findings...

Allergic asthma is characterized by chronic airway inflammation and hyperreactivity and is thought to be mediated by an adaptive T helper-2 (Th2) cell-type immune response. Here, we demonstrate that type 2 pulmonary innate lymphoid cells (ILC2s) significantly contribute to production of the key cytokines IL-5 and IL-13 in experimental asthma. In naive mice, lineage-marker negative ILC2s express...

We previously observed genotoxic effects of carbon black nanoparticles at low doses relative to the Danish Occupational Exposure Limit (3.5 mg/m(3)). Furthermore, DNA damage occurred in broncho-alveolar lavage (BAL) cells in the absence of inflammation, indicating that inflammation is not required for the genotoxic effects of carbon black. In this study, we investigated inflammatory and acute p...

The aim of this experimental study was to evaluate the protective effect of erdosteine on lung injury induced by ischaemia-reperfusion (IR) of the lower extremities of rats. Wistar albino rats (n = 21) were divided into three groups. In the IR group (n = 7), the aorta was cross-clamped for two hours, followed by one hour of reperfusion. In the erdosteine group (n = 7), animals were pretreated w...

Respiratory diseases caused by bacteria are common to all of ages of ostrich (Struthio camelus). Young chicks, however are more susceptible, and are considered a major hindrance in successful ostrich farming. Using culture dependent techniques, a diminutive prospect of bacterial pathogens and corresponding diseases associated with respiratory system has been described. Here we report the first ...

We applied energy-dispersive x-ray fluorescence to the determination of abnormally present elements or abnormal concentrations of elements in human broncho-alveolar lavage fluids. The low detection limits and the ability to perform multi-elemental analysis permit one to establish or confirm occupational exposure of workers. We also describe different methods used to check our method and our res...

Methods Eight female Large White-Landrace pigs (33.9 ± 2.1 Kg) were anesthetized, tracheally intubated and connected to a mechanical ventilator. Ultrasound-guided arterial cannulation was performed, and a Swan-Ganz catheter was inserted into the jugular vein for hemodynamic monitoring. Following surgical preparation, and 4 hours thereafter, 15 mL of 10 cfu/mL of S. pneumonia serotype 19A, resis...

Macrophages play a central role in the pathogenesis of inflammatory and fibrotic lung diseases. However, alveolar macrophages (AM) are poorly available in humans to perform in vitro studies due to a limited access to broncho-alveolar lavage (BAL). In this study, to identify the best alternative in vitro model for human AM, we compared the phenotype of AM obtained from BAL of patients suffering ...

Re-expansion of a collapsed lung increases the microvascular permeability and causes re-expansion pulmonary edema. Neutrophils and their products have been implicated in the development of this phenomenon. The small GTP-binding proteins Rho and its target Rho-kinase (ROCK) regulate endothelial permeability, though their roles in re-expansion pulmonary edema remain unclear. We studied the contri...
