Emphysema was produced experimentally in rats by administration of porcine pancreatic elastase at dose levels of 75, 100, 125, and 150 units elastase activity/100 g body wt. All doses studied were equally effective in producing emphysema. Dose levels

Male Wistar rats were exposed to bituminous coal dust considered to have high potential for induction of coal workers' pneumoconiosis (CWP). They developed lesions similar to simple CWP as described in human subjects. Comparable lesions observed were

Three species of rodents exhibited respiratory distress when exposed to aerosols of sodium combustion products, the major constituent of which was shown to be sodium carbonate. At the higher doses, animals died during or shortly after 2 hr exposures.

Normal and lung-impaired rats were compared after exposure to SO2 and/or (NH4)2SO4 for 4 or 8 months, or for 8 months plus 3 months recovery. Young adult male Sprague-Dawley rats were pretreated intratracheally with either physiologic saline (normal

Exposure to particulates from uranium ore dust and diesel exhaust soot provoked inflammatory and proliferative responses in lungs. Also exposure to radon and radon daughters yielded increased occurrences of bronchiolar epithelial hyperplasia and meta
