血浆蛋白在此指什么而言？

Inflammation is the process by which circulating leukocytes and plasma proteins are brought into sites of infection in tissues and are activated to destroy and eliminate the offending agents. Inflammation is also the major reaction to damaged or dead cells unrelated to infection and to accumulations of abnormal substances in cells and tissues.

炎症是循环白细胞和血浆蛋白被带到组织感染部位并被激活以破坏和消除病原体的过程。炎症也是对感染无关的受损或死亡细胞以及细胞和组织中异常物质积聚的主要反应。
