Comparison of the protective effect of circulating TNF-?removal between immunoadsorption and Amberlite XAD-7 absorption on endotoxin shock / 中华肾脏病杂志

ABSTRACT

To estimate the protective effect of removing circulatory TNF-a immunoadsorpnon or Amberlite XAD-7 absorption respectively on endotoxin shock. Methods New Zealand white rabbits injected with lethal dose of endotoxin underwent hemoper-fusion through immunoadsorbent or Amberh'te XAD-7 respectively. Plasma TNF-a levels were detected, and the sorbent efficiency and survival rate were observed. Results After 2 hours hemoperfusion through immunoadsorbent or Amberlite XAD-7 respectively, plasma TNF levels were significandy lower than those in die control group, especially, die sorbent efficiency of immunoadsorp-tion was higher dian dial of Amberlite XAD-7 adsorption. Conclusion Compared widi die nonspecific Amberlite XAD-7 adsorption, immunoadsorption might be a specific and more effective therapy of endotoxin shock.
