title: Study on free and total urinary hydroxyproline in old men.
abstract: The present study deals with urinary free and total hydroxyproline (HOP) in a group of adults between 63-93 years old, admitted in a sanatorium for geriatries. The average value of the free HOP on the whole group was of 1.28 mg/24 hours (0.52-2.10) and that of the total HOP was of 16.54 mg/24 hours (10.7-27.94). The free HOP does not show differences as compared to the adults; but the total one decreases in old people. The data obtained are discussed and compared with the literature.
