[The effect of triiodothyronine and catecholamines on the stability of trace effects of cold adaptation in rats].

The role of three-iodine-thyronine, noradrenaline (NA), adrenaline (A), reserpine and propranolol in extinguishing of trace-effects of the long-term cold adaptation was studied in rats. A possibility to control the process of the temperature disadaptation through administration of different hormonal drugs, was shown. Three-iodine-thyronine and NA proved to be the most effective in this respect. Weakening of sympathetic-adrenal effects by means of combined reserpine and propranolol during the disadaptation accelerated the process of extinguishing of practically all the trace-effects of the long-term cold adaptation.
