3-hr exposure to air at +5 degrees C of unrestrained rats evoked a relative reduction of blood volume in vessels of the skin, skeletal muscles, abdominal and pelvic organs (except liver). Increase of the blood volume occurred in the brain, thoracic organs, and in the liver. No significant decrease of the rectal temperature was noticed at that, in spite of cooling of the skin of different parts of the body and tail. Cooling of restrained rats at +5 degrees C during 1 and 3 hrs decreased the rectal temperature. The main direction of the blood redistribution involved its removal from the liver to the deep muscle tissues. At the beginning of the cooling and immediately after self--warming the relative increase of the blood volume was more obvious in the skeletal muscles of the anterior body parts.
将无束缚大鼠置于5摄氏度空气中暴露3小时，会引起皮肤、骨骼肌、腹部和盆腔器官（肝脏除外）血管内血容量相对减少。脑、胸部器官和肝脏中的血容量增加。尽管身体不同部位的皮肤和尾巴都有降温，但此时未观察到直肠温度有明显下降。将束缚大鼠在5摄氏度下冷却1小时和3小时会使直肠温度降低。血液重新分布的主要方向是从肝脏转移到深部肌肉组织。在冷却开始时以及自我升温后立即观察到，身体前部骨骼肌中的血容量相对增加更为明显。
