1 内毒素的病理生理内毒素为分子量700000的具有多种生物活性的细胞溶解产物,是革蓝氏阴性菌细胞外壁溶解后释放的脂多糖。平时为机体门脉血中的正常存在。栖居在胃肠道下端的革蓝氏阴性菌属是机体内毒素的主要来源。当革蓝氏阴性菌感染,肠道内毒素增加网状内皮系统功能受损任何一个因素发生,即可产生内毒素血症。但近年来Goris等发现创伤与 1 endotoxin pathophysiological endotoxin is a molecular weight of 700000 with a variety of biological activity of cell lysate is Gram-negative bacteria dissolved in the outer wall of the lipopolysaccharide released. Usually for the normal existence of the body portal vein blood. Gram-negative bacteria that inhabit the lower gastrointestinal tract are the main source of toxins in the body. When Gram-negative bacteria infection, intestinal endotoxin increased reticuloendothelial system dysfunction occurred in any one factor, you can produce endotoxemia. However, Goris et al found trauma in recent years
