Abstract
Urinary 17-ketosteroid (17-KS) measures were obtained from rats 50, 100, 330 and 600 days old during a normal period and during a shock-stress period. No differences were observed between the age groups for the normal period, but 50- and 100-day-old Ss manifested significantly greater 17-KS values during the stress period as compared to the 330- and 600-day-old Ss.
