THE EFFECT OF INTERFERENCE WITH RESPIRATION ON THE CONTROL OF BODY-TEMPERATURE IN WHITE RATS AND NEW ZEALAND RABBITS

Abstract

Hypothermia was produced in rats and rabbits by wrapping with adhesive tape to restrict respiration and exposure at 2[degree]-4[degree]C. Wrapped rats exposed at high temps. showed a rise in body-temp. The neutral point was at 31[degree]C air temp. Variations in temp. curves with changes in conditions are shown. Rabbits wrapped and exposed at 2[degree]-6[degree]C showed a rise in the CO2 content and a fall in O2 content of the blood which was correlated with the body-temp. fall.
