作者赴海拔5000米高原对Hb(血红蛋白)、Hct(血球压积)等反映红细胞变化的指标进行了较长时间的观察。结果发现在进入高原后Hb和Hct即见持续增高,于第8周时上升到高峰,此后二者处于稳定状态。红细胞增生的速率及程度与受检者原居住地的海援高度和年龄有关,同时也存在着明显的个体差异。第8周时,有5例(占25％)达到高原红细胞增多症的血液学标准,其中有3例出现了高原红细增多症的症状和体征。并就此进行了讨论。 The author went to the altitude of 5000 meters plateau on the Hb (hemoglobin), Hct (hematocrit) and other indicators of changes in red blood cells were observed for a long time. The results showed that after entering the plateau Hb and Hct that see continued to increase in the first 8 weeks rose to its peak, after which the two were stable. The rate and extent of erythrocyte hyperplasia were related to the height and age of the sea aid recipients’ original place of residence, and obvious individual differences also existed. At 8 weeks, 5 (25%) met the hematological criteria for HPT, and 3 of them developed symptoms and signs of HPT. And discussed this.
