Effects of acute cold exposure (10 degrees C for 60 min) on the concentrations of adrenocorticotropin (ACTH) and zinc in plasma were investigated in seven healthy male students. There were no significant changes in total zinc, albumin-bound zinc, and alpha 2-macroglobulin-bound zinc concentrations throughout the experimental period. On the other hand, ACTH concentration increased markedly during cold exposure. In addition, a statistically significant inverse relationship existed between the changes in ACTH and albumin-bound zinc values during the experiment. These results suggest that acute cold exposure produces elevated plasma ACTH levels, with resulting zinc redistribution in the human body.
对7名健康男学生研究了急性冷暴露(10摄氏度,60分钟)对血浆中促肾上腺皮质激素(ACTH)和锌浓度的影响。在整个实验期间,总锌、白蛋白结合锌和α2-巨球蛋白结合锌的浓度没有显著变化。另一方面,冷暴露期间ACTH浓度显著升高。此外,实验期间ACTH变化与白蛋白结合锌值之间存在统计学上显著的负相关关系。这些结果表明,急性冷暴露会使血浆ACTH水平升高,从而导致人体锌的重新分布。
