Increased Excretion of Dehydroascorbic and Diketogulonic Acids by Rats in the Cold.

Abstract
The urinary ascorbic acid, dehydroascorbic acid, and diketogulonic acid of adult albino rats at environmental temps, of 21[degree]C for control and 0[degree]C for exptl. periods was detd. The excretion of ascorbic acid at 0[degree]C was increased 53%, dehydroascorbic acid 186%, and diketogulonic acid 500% above the values obtained on the same rats at 21[degree]C.
