Anti-inflammatory cytokine release by alveolar macrophages in pulmonary sarcoidosis.

abstract：:The distribution of ventilation-perfusion (VA/Q) ratios during bronchoconstriction measured with the multiple inert gases elimination technique is frequently bimodal. However, the topographic basis and the cause of that bimodality remain unknown. In this article, regional VA/Q is quantified by three-dimensional positr...
