The effect of simulated weightlessness on thermoregulation was studied in 5 subjects. The experiment consisted of 3d baseline measurements, 7d head-down bed rest and 2d recovery. Circadian rhythm was assessed by continuous measurements of rectal temperature and skin temperature with 2h intervals. Heat Stress Protein 70 (HSP70) was measured by Western-blot Dot method and the facial surface temperature distribution was measured by HR-2 infrared thermography. The results showed that rectal temperature keeps the wake-sleep variation, but the circadian rhythm changed during bed rest, and the change of rectum temperature rhythm appeared mainly in the early-days of bed rest; HSP70 and facial surface temperature increased during bed rest.
对5名受试者进行了模拟失重对体温调节影响的研究。实验包括3天的基线测量、7天的头低位卧床休息和2天的恢复。通过每隔2小时连续测量直肠温度和皮肤温度来评估昼夜节律。采用蛋白质免疫印迹斑点法测定热应激蛋白70（HSP70），并通过HR-2红外热成像仪测量面部表面温度分布。结果显示，直肠温度保持着清醒-睡眠的变化，但卧床休息期间昼夜节律发生了改变，直肠温度节律的变化主要出现在卧床休息的早期；卧床休息期间HSP70和面部表面温度升高。
