THE URINARY EXCRETION OF 17-KETOSTEROIDS BY MEN UNDER FIELD CONDITIONS IN EXTREME COLD

Tests were conducted to determine the excretion of 17-ketosteroids on a group of seven subjects participating in two bivouac exercises, first under conditions of a temperate climate, and later under arctic conditions, which were so designed as to be similar except for the factor of extreme cold. When the excretion of 17-ketosteroids by seven healthy soldiers under field conditions in a temperate climate was compared with their excretion of these substances under field conditions in extreme cold, no significant changes were noted. The determination of the excretion of 17-ketosteroids in the urine did not indicate a stress due to cold under the circumstances described in this report.
