Effects of bombesin on body temperature and oxygen consumption in food-deprived rats.

The present study measured oxygen consumption and core body temperature following central injections of bombesin (1.0 microgram) in food-deprived rats. Oxygen consumption did not differ for bombesin- and control-injected rats while mean core body temperature decreased significantly following bombesin administrations. Present findings suggest separate mechanisms of heat loss for bombesin-induced hypothermia in cold-exposed and food-deprived rats.
