一般认为血沉增快是与血浆成分的改变,特别是纤维蛋白原或球蛋白含量增加,以及红细胞数减少有关。红细胞具有悬浮稳定性。正常情况下,红细胞是具有细胞膜的胶体物质,除具有一定张力外,细胞膜外还有一层水化膜,使红细胞相互隔离。红细胞表面还带负电荷,因此,红细胞互相排斥,而不易粘合下沉,呈现稳定的悬浮状态或缓慢下降。
It is generally believed that the rapid increase of ESR is associated with changes in plasma components, especially fibrinogen or globulin, and a decrease in the number of red blood cells. Erythrocytes have suspension stability. Under normal circumstances, red blood cells is a cell membrane with colloidal substances, in addition to a certain tension, the cell membrane and a layer of hydration membrane, the red blood cells isolated from each other. Erythrocyte surface is also negatively charged, therefore, red blood cells exclude each other, but not easy to sink, showing a stable suspension or slow decline.
