Twenty subjects each were rapidly inducted by road to 3200 ad 3771 m. Serum and urinary sodium, potassium, calcium, and magnesium were measured during 10 d at high altitude. At 3200 m, only serum potassium increased significantly on the 10th day. At 3771 m, serum potassium did not increase. Serum sodium generally remained low, serum magnesium increased, while calcium decreased significantly. Urinary volume over 24 h decreased more and for longer duration at 3771 m than at 3200 m. Urinary cations did not change significantly at 3200 m. At 3771 m, sodium and potassium excretion decreased on days 1 and 3 later returned towards preinduction levels. Magnesium and calcium decreased throughout the high-altitude stay. Significant changes were noticed in serum and urinary cations on exposure to high altitude when adequate caloric intakes were not ensured.
20名受试者通过陆路迅速被送至海拔3200米和3771米处。在高海拔地区停留10天期间，测量血清和尿液中的钠、钾、钙和镁。在海拔3200米处，仅第10天血清钾显著升高。在海拔3771米处，血清钾未升高。血清钠通常保持较低水平，血清镁升高，而钙显著降低。海拔3771米处24小时尿量减少更多且持续时间更长。在海拔3200米处尿阳离子无显著变化。在海拔3771米处，第1天和第3天钠和钾排泄减少，之后恢复到诱导前水平。在整个高海拔停留期间镁和钙减少。当未确保充足热量摄入时，暴露于高海拔时血清和尿阳离子出现显著变化。
