【摘要】 检测０～ １０００ｓ－１切变率条件下大鼠和小鼠红细胞变形指数（ＤＩ值）的变化，结果发现：（１）ＤＩ值随切变率升高而递增。（２）大鼠在切变率为５００ｓ－１以下时，ＤＩ值随切变率升高显著递增，５００ｓ－１以下各组间ＤＩ值有显著或非常显著差异，各组与５００ｓ－１以上各组间ＤＩ值也有显著或非常显著差异；小鼠在切变率为４００ｓ－１以下时， ＤＩ值随切变率升高显著递增，４００ｓ－１以下各组间 ＤＩ值有显著或非常显著差异，各组与 ４００ｓ－１以上各组间 ＤＩ值也有显著或非常显著差异。（３）大鼠在切变率为 ５００ｓ－１以上时，ＤＩ值随切变率升高递增，但无显著差异；小鼠在切变率为 ４００ｓ－１以上时，ＤＩ值切变率升高递增，亦无显著差异。提示在切变率为５００ｓ－１或４００ｓ－１以上时，ＤＩ值接近极限。（４）不同种生物，红细胞易变形的切变率范围各异。更多还原

【Abstract】 Ektacytometer type LG-B-190 was used to check up the condition of change of the index(DI value) of erythrodegeneration in rats and mice in the shear rate rang of 0-1000S-1 / The results indicated that; 1. DI value increased progressively as the shear rate rose. 2. In case the shear rate in rats was lower than 500S-1 ,the DI value increased remarkably as the shear the rose. In case the shear rate in mice was lower than 400S-1 , the DI value increased considerably with the rise of the shear rate. 3. In case the shear rate in rats was higher than 500S-1 , the DI value increased progressively with the rise of the shear rate but had not marked difference; in case shear rate in mice was higher than 4000S-1, the DI value increased progressively as the shear rate grew but had not marked difference, either. 4.According to different species of animals, the range of the shear rate of easily-degenerating erythrocyte was not the same.更多还原
