title: Collagen breakdown and ammonia inhalation.
abstract: Measurement of several urinary metabolites of hydroxylysine indicates that considerable collagen degradation occurred in four individuals immediately after they had inhaled concentrated ammonia vapors. Since clinical and/or radiological evidence of intense upper respiratory and pulmonary inflammation were evident, it is likely that collagen degradation occurred at the level of the respiratory system.
