本文目的是探讨吞噬细胞受到创伤、营养不良及感染的影响时,其非特异性防卫机理的重要性。休克和创伤后发生的防卫机理的改变,可增加感染的发生率。在此背景下创伤后的营养不良会损害吞噬细胞的防卫力,进一步使孱弱的病人受到损害。一旦发生感染,将加重抑制吞噬细胞的防卫。加重 The purpose of this article is to explore the importance of nonspecific defense mechanisms in phagocytes when they are affected by trauma, malnutrition and infections. Shock and post-traumatic changes in the defensive mechanism can increase the incidence of infection. In this context, post-traumatic malnutrition can impair the defensive power of phagocytes and further compromise frail patients. In the event of infection, will aggravate the defense of phagocytes.
