Amiodarone, a cardiac antiarrhythmic agent, has been associated with the development of interstitial pulmonary fibrosis in patients receiving prolonged therapy with the drug. To further assess the toxic effects of amiodarone on lung tissue, Syrian hamsters were given a single intratracheal insufflation of the agent and evaluated for histologic evidence of(More)
Concentrations of alpha1-antitrypsin were measured in 80 specimens of amniotic fluid collected at various stages of pregnancy. Levels remained relatively unchanged throughout gestation, with a median concentration of 10.0 mg/100 ml at 12-24 weeks, 18.7 mg/100 ml at 34-37 weeks, and 16.2 mg/100 ml, after the 37th week. In three instances where the infant(More)
A monolayer of a clone of endothelial cells derived from rat lung cells (RLE) was overlaid with 1 M urea to extract the surface proteins. Hydrolysis and SDS-gel electrophoresis of the urea extracted cell surface proteins (UCSP) yielded four peptides of 350,000, 84,000, 66,000 and 18,500 molecular weight. Of these only the 66,000 and 18,500 molecular weight(More)
