[Role of changes in the body's heat content during the development of thermoregulatory responses]

Summation of temperature signals from different body parts was shown to occur in the temperature homeostasis maintenance, as revealed by the value delta to average . m . c, where delta to average--increment of the body average temperature, m--body mass, c--body specific heat. Raise of the rabbit heat condition by 245.9 +/- 35.8 cal/kg at ambient temperature 19-21 degrees C induces ear vasodilatation which is the thermoregulatory response aimed at the heat loss. Dropy of the rabbit heat condition by 266.9 +/- 21.5 cal/kg at ambient temperature 28-30 degrees C induces ear vasoconstriction. The heat condition seems to the object of regulation in the organism thermoregulation system.
