The content of polyamines, spermidine and spermine in the brain and liver was studied in rats during acclimation to cold for 45 days. In the brain the amount of spermidine after one and three days does not change, on the 7th and 15th day it decreases and by the end of acclimation returns to the control value. The content of spermine lowers by 29% by the third day of acclimation and on the 7th day returns to the initial level and does not change up to it end. In the liver the amount of spermidine rises significantly on the third day of acclimation, returns to the control level on the 7th day and then its amount falls. The content of spermine is increased in all period of acclimation and only by the 45th day it returns to its initial level.
在大鼠适应寒冷45天的过程中，对其大脑和肝脏中的多胺、亚精胺和精胺含量进行了研究。在大脑中，亚精胺的含量在第1天和第3天没有变化，在第7天和第15天下降，到适应期结束时恢复到对照值。精胺的含量在适应的第3天降低了29%，在第7天恢复到初始水平，直到适应期结束都没有变化。在肝脏中，亚精胺的含量在适应的第3天显著上升，在第7天恢复到对照水平，然后其含量下降。精胺的含量在适应的所有阶段都增加，直到第45天才恢复到初始水平。
