Acute experimental silicosis. Lung morphology, histology, and macrophage chemotaxin secretion.


The acute inflammatory reaction in the lungs of guinea pigs produced by the intratracheal injection of silica was assessed by histologic studies and whole-lung lavage 1, 2, 4, 7, and 14 days after the intratracheal instillation of quartz particles or saline. In addition, lavaged macrophages were cultured in vitro, and the media were assayed for chemotactic… (More)
