可变形性是红细胞生理学的一个重要方面,已经在人体红细胞中进行了广泛的研究。使用粘度测定技术研究了25种不同动物的红细胞。红细胞直径3.3 μ。M在山羊到11.4亩。M是象海豹。当施加流体剪切应力时,大多数种类的红细胞容易变形。应力单元的变形能力指数定义为(长-宽)/(长+宽)与单元尺寸相关。侏儒山羊、山羊、八丹加马和微型马4种动物红细胞畸形程度低于大多数物种。骆驼和羊驼红细胞呈椭球状,在应力场中不变形,而是定向。
Deformability is an important aspect of erythrocyte physiology and has been extensively studied using human red cells. Erythrocytes from 25 different animals were studied using a viscometric technique. Erythrocyte diameters ranged from 3.3 .mu.m in the goat to 11.4 .mu.m for the elephant seal. Erythrocytes from most species deformed readily when a fluid shear stress was applied. A deformability index of the stressed cell defined as (length - width)/(length + width) correlated with cell size. The erythrocytes of 4 animals (pygmy goat, goat, Batanga horse and miniature horse) deformed less than most species. Camel and llama erythrocytes, which were ellipsoidal, did not deform but oriented in the stress field.
