[The nature of the changes in "central" body temperature in cold exposures in a model of rabbit thermoregulation].
The heat-physical model of the rabbit body with the homeostasis regulation served for the study of "central" temperature behaviour in a thermochamber with the temperature dropping from 22 degrees C to 2 degrees C. The value and character of the "central" temperature changes depended on the initial level of peripheral temperature. In case of a high level of initial heat state, the temperature drops at the start period of the cooling, whereas in case of a low initial level the temperature of the body's "nucleus" increases. The model experiments illustrate the changes of rectal temperatures at the start of the cooling, provided an area of insensitivity is admitted in the work of the rabbit thermoregulation system.
