Abstract:
Urinary 17-hydroxycorticosteroids, 17-ketosteroids and 16α-hydroxydehydro epi androsterone from eighty-six healthy subjects from the ages of 2 to 79 of both sexes were determined quantitatively by elution chromatography on cation exchange resin. Daily urinary excretions of 17-hydroxycorticosteroids and 17-ketosteroids increased from childhood to the ages of 15 to 40 and then decreased gradually with advancing ages over 60 to 79. The ratio of tetrahydrocortisone to tetrahydrocortisol decreased gradually from adolescence to old age. The ratios of 17-ketosteroids to 17-hydroxycorticosteroids and C 19 O 2 - 17-ketosteroids to total 17-ketosteroids were much higher between the ages of 20 and 40 than at other ages particularly in males. The ratios of aetiocholanolone to androsterone and tetrahydrocortisol to allo-tetrahydrocortisol seemed to be lower between the ages of 15 and 40 than at other ages. It was possible to determine the daily urinary excretions of 16α-hydroxydehydro epi androsterone only in subjects over the age of 15, particularly between the ages of 20 and 40.
