ROLE OF ENDOGENOUS CARBON MONOXIDE IN ENDOTOXIN SHOCK
摘要
Abstract
Objective.To study the role of endogenous carbon monoxide (CO) in endotoxin shock. Methods. The changes of CO levels and the effects of zinc protoporphyrin IX (ZnPP)
an inhibitor of hemeoxygenase (HO)
in endotoxin shock and the efficacy of hemin
an inducer of HO were investigated. Results.The plasma CO levels were found to be significantly increased during the course of endotoxin shock. Injection of ZnPP was shown to abrogate the endotoxininduced hypotension and metabolic derangements markedly. Administration of hemin to healthy rabbits revealed the hypotension and metabolic derangements similar to the animals given endotoxin. Conclusion.CO is a newly found endogenously produced mediator which may play an important role in the pathogenesis of endotoxin shock.
