Contribution of Nonshivering Thermogenesis to Stress-induced Hyperthermia in Rats

Abstract

Restraint for 2 min increased heat production and brown adipose tissue (BAT)-thermogenesis in rats at 27°C. These increases continued for 15-20 min after the release from restraint. After sectioning sympathetic nerves to the BAT, restraint did not produce BAT-thermogenesis. These results indicate that BAT is responsible for the stress-induced hyperthermia in rats.
