Abstract

During ten-month stay at 3200 m altitude in the Tien Shan mountains a significant increase of systolic pressure and practically unchanged diastolic one in pulmonary artery were recorded in rats. A redistribution of the blood flow and volume occurred. An increased oxygen blood capacity was maintained through an elevated hemoglobin content in erythrocytes and an increase of their size but not of their number.

摘要

在天山山脉海拔3200米处停留10个月期间，大鼠肺动脉收缩压显著升高，舒张压几乎未变。血流和血容量发生了重新分布。通过提高红细胞内血红蛋白含量及其大小而非数量，维持了血氧容量的增加。
