亲和吸附材料特异性清除肠源性内毒素有效性和安全性探讨
Efficacy and safety of the removal of intestinal endotoxin in the blood by affinity adsorption materials
摘要
Abstract
Objective To investigate the efficacy and safety of the affinity adsorption material for removal of intes-tinal endotoxin in the blood. Metheds To establish a canine model of intestine-derived endotoxemia by ligation and perfo-ration of the appendix. Hemoperfusion was performed to treat the endotoxemia in model dogs. In the experiment,we moni-tored vital signs and detect the content of endotoxin and blood physiological and biochemical indexes at different time points. Results The endotoxin content was(0.49 ± 0.22),(0.034 ± 0.00)Eu/mL after hemoperfusion for 1 and 2 hours,compared with that before the beginning of perfusion(7.25 ± 1.18)Eu/mL,showing a significant difference(P <0.05). After treatment for 2 hours,the average clearance rate was 99.52%. White blood cells,red blood cells,hemoglo-bin,platelets,total protein,albumin,globulin,alanine aminotransferase,aspartate aminotransferase,urea and creatinine index were significantly decreased after perfusion(P < 0.05). The index values were in a normal range and vital signs were stable during the perfusion. Conclusions The affinity adsorption material developed by our team can effectively re-move endotoxin in the blood of experimental dogs and has good blood compatibility.关键词
