. The ancient drug colchicine has repeatedly been proposed as a novel drug for therapy of pulmonary fibrosis. The present study was undertaken to add to the knowledge on colchicine's antiinflammatory and antifibrotic properties and thus help determine its actual rank in the treatment of pulmonary fibrosis. In vitro cell culture experiments with stimulated and unstimulated normal donor peripheral...
. Nocturnal worsening of symptoms affects a large number of patients suffering from asthma. Recent studies show that airway inflammation underlies nocturnal awakenings and increased airway hyperreactivity. These studies, however, yield conflicting results concerning the pathogenesis of the disease, making it difficult to understand the mechanisms involved in sustaining nocturnal asthma. This article...
. Chronic obstructive pulmonary disease (COPD) induces changes in daily activities and mood. Health-related quality of life (HRQL) measures are of particular relevance in the management of such patients, but predictors of HRQL have rarely been investigated. The aim of this study was to seek factors predicting HRQL in severe COPD patients under long term oxygen therapy (LTOT). The pulmonary function...

. This article starts with a brief account of the history of research on pulmonary surfactant. We will then discuss the morphological aspects and composition of the pulmonary surfactant system. We describe the hydrophilic surfactant proteins A and D and the hydrophobic surfactant proteins B and C, with focus on the crucial roles of these proteins in the dynamics, metabolism, and functions of pulmonary...

Our laboratory has demonstrated recently that pulmonary inflammation induced by acute ozone exposure is much more severe in late stage pregnant and lactating rats than in postlactating rats or age-matched virgin females. It is currently widely believed that such pulmonary damage results, at least in part, from the reaction of ozone at sites of unsaturation in phospholipid fatty acid (PLFA) molecules...
The soluble form of intercellular adhesion molecule-1 (sICAM-1) might be a serum parameter of inflammatory activity gauging cellular interactions with possible relevance in sarcoidosis. To address this question we measured sICAM-1 by enzyme-linked immunosorbent assay in serum and shedding of this molecule by bronchoalveolar lavage (BAL) cells in sarcoidosis patients (44 and 40, respectively) and in...
In this review the effects of oxidant inhalation on the pulmonary surfactant system of laboratory animals are discussed. Oxidant lung injury is a complex phenomenon with many aspects. Inhaled oxidants interact primarily with the epithelial lining fluid (ELF), a thin layer covering the epithelial cells of the lung which contains surfactant and antioxidants. In the upper airways this layer is thick...
. To investigate the influence of interleukin-1β (IL-1β) on airway epithelial cell growth, we measured [3H]thymidine incorporation and cell numbers of cultured porcine tracheal epithelial cells in the presence or absence of human recombinant IL-1β with or without the following: goat antiporcine polyclonal antibody to platelet-derived growth factor (PDGF); IL-1 receptor antagonist; indomethacin; PD-145065,...
