Effect of environmental particulates on cultured human and bovine endothelium. Cellular injury via an oxidant-dependent pathway.

The effects of respirable environmental fibers on cultures of human umbilical vein and bovine pulmonary artery endothelial cell monolayers were studied. Interaction among endothelial cell monolayers and amosite and chrysotile asbestos, attapulgite, fiberglass, or latex beads resulted in rapid phagocytosis of the particulates. A gradient of time-dependent… CONTINUE READING
