通过对高原土生动物不同海拔血液流变学特征及其到平原后血液流变学变化的观察,表明这类动物的红细胞压积随海拔高度增加,只轻度增高,全血粘滞性较低,红细胞聚集性较小,这既有利于红细胞携带更多的氧到组织也利于组织灌注,在血液携氧和运氧过程中发挥了最佳效率。这类动物到平原初期,红细胞压积及全血粘度极度降低,经过一阶段机体的调整,红细胞压积及全血粘度逐渐回升,其表现与移居高原动物再返平原后的反应截然不同。
The observation of hemorheological features at different altitudes and the changes of hemorrheology after exposure to the plain showed that the hematocrit of these animals increased with altitude, slightly increased, and the whole blood viscosity was low , Less aggregation of red blood cells, which is beneficial to red blood cells to carry more oxygen to the tissue is also conducive to tissue perfusion, the oxygen carrying oxygen in the blood and oxygen play the best efficiency. These animals to the early plains, hematocrit and whole blood viscosity was extremely reduced, after a period of body adjustment, hematocrit and whole blood viscosity gradually rise, the performance and migrate to plateau animals and then returned to the plain after the reaction is very different.
