Abstract
Summary
White rats were exposed to a temperature of 3-5°C for periods varying from 24 hours to 35 days. Adipose tissue from animals so exposed from 1 to 20 days or for 35 days produced 3 to 4 times more FFA than did tissue from animals maintained at room temperature. However, if the animals were fasted before the tissue was removed, these differences virtually disappeared. It is evident that studies of participation of the adipose tissue in the adjustment of the rat to a cold environment should be interpreted relative to the nutritional state of the animal at the time the studies are made.
