模拟失重对兔红细胞形态及生成的影响

为探讨微重力下血液变化机理，观察了头低位兔血液红细胞形态及骨髓造血功能的变化，发现头低位组兔血液中的畸形红细胞增多，骨髓中出现了稍密集的造血细胞，网状细胞核孔增多，内质网扩张，幼稚红细胞进入血窦，巨噬细胞吞噬幼稚红细胞，血窦内皮细胞空泡化等现象。实验结果表明，短期模拟失重以地红细胞形态和骨髓造血功能有一定的影响。

Effects of Simulated Weightlessness on Hemopoiesis and Morphology of Red Blood Cell in Rabbits

Effects of simulated weightlessness(SWL) Head- down - tilt on red blood cell morphology and bonemarrow function in rabbits were observed. After SWL, increased number of abnormal red blood cells, more concentrated hematopoietic cells, change of hemopoietic microenvironment, more nuclear pores in reticulacytes, expanded endoplasmic reticulum in reticulocytes , emerging of juvenile red blood cells into bone marrow blood sinus and megakaryocyte, and bubbles in endothelial cells were observed. The results show that SWL has certain effects on the morphology and function of red blood cell and bone marrow.
