The use of an intestinal thermode for studying thermoregulation of the golden hamster.
Intestinal cooling induces a normal metabolic response compensating heat loss in the euthermic golden hamster. The hypothalamic and subcutaneous temperatures change unpredictably and the threshold hypothalamic temperature for the induction of cold thermogenesis, similarly as the sensitivity of the regulator related to changes in hypothalamic temperature vary considerably, however. It seems that the thermal input from the hypothalamus does not contribute significantly to the control of cold thermogenesis in euthermic golden hamsters during intestinal cooling. The use of an intestinal thermode itself is not suitable for quantitative studies of thermoregulation in the golden hamster.
