门静脉内毒素来源于肠内菌丛,体外实验可见到肠内毒素转移到门静脉是由体外粘膜单方向进入到浆膜。一、内毒素与血清蛋白血清内毒素的相互作用已被全面研究过,大量实验证明,各种血清蛋白可以和脂多糖结合。据报道,高密度脂蛋白、低密度脂蛋白、细菌渗透性增加因子、阳离子性抗菌蛋白和血清白蛋白能和脂多糖相互作用, Portal venous endotoxin from the intestinal flora, in vitro experiments can be seen in the intestinal endotoxin transfer to the portal vein by unidirectional in vitro mucosal access to the serosa. First, the interaction of endotoxin and serum protein endotoxin has been fully studied, a large number of experiments show that a variety of serum proteins can be combined with lipopolysaccharide. It has been reported that high density lipoprotein, low density lipoprotein, bacterial permeability increasing factor, cationic antimicrobial protein and serum albumin can interact with lipopolysaccharide,
