营养不足及吞噬细胞防御机理衰竭是脓毒性损伤病人和伴有感染或血管内凝血的危重病人中发生器官功能衰竭的重要因素。蛋白质-热卡不足可削弱机体的抵抗力,从而增加脓毒症的病残率和死亡率。也有资料证实,饥饿及营养不良常可抑制网状内皮系统(RES)吞噬细菌和测试微粒的作用,以及降低其它防御性参数。这都说明,对损伤和感染的抵抗力降低,部分是与代谢或营养所致的吞噬功能不良有关。血浆纤维结合素(Fibronectin)或冷-不溶 Undernutrition and phagocyte defensive mechanisms Failure is an important factor in the development of organ failure in septic patients and critically ill patients with infection or intravascular coagulation. Protein - lack of heat card can weaken the body’s resistance, thereby increasing the morbidity and mortality of sepsis. There is also data to confirm that starvation and malnutrition often inhibit the reticuloendothelial system (RES) phagocytosis of bacteria and test the role of particles, and reduce other defensive parameters. All this shows that the resistance to damage and infection is reduced, partly due to metabolic or nutritional dysfunction caused by phagocytosis. Fibronectin or cold-insoluble
