Iron chelates bind nitric oxide and decrease mortality in an experimental model of septic shock.
The hydroxamic acid siderophore ferrioxamine B [FeIII(HDFB)+] and the iron complex of diethylenetri-aminepentaacetic acid [FeIII(DTPA)2-] protected mice against death by septic shock induced by Corynebacterium parvum + lipopolysaccharide. Although FeIII(DTPA)2- was somewhat more effective than FeIII(HDFB)+, the iron-free ligand H4DFB+ was significantly more effective than DTPA. The hydroxamic a...
متن کاملDifferential expression of inducible nitric oxide synthase in septic shock.
During cardiopulmonary bypass (CPB), the septic patient has markedly decreased peripheral vascular resistance as a consequence of endotoxin release from microorganisms. This decrease in peripheral vascular resistance is the result of endotoxin-induced nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) and endothelial nitric oxide synthase (eNOS). iNOS and eNOS are responsible ...
متن کاملAnti-inflammatory Effect of Ethanolic Extract of Euphorbia myrsinites in Lipopolysaccharide-induced Septic Shock in Mice
Background and purpose: Many herbs including Euphorbia have immunomodulatory properties. The aim of this study was to evaluate the immunomodulatory effects of the ethanolic extract of E.myrsinites. Materials and methods: In this experimental study, 40 Swiss albino male mice were randomly divided into 4 groups. Group A included healthy mice, group B was induced by lipopolysaccharide (LPS), grou...
متن کاملEffects of lipopolysaccharide-induced septic shock on rat isolated kidney, possible role of nitric oxide and protein kinase C pathways
Objective(s): Pathophysiology of sepsis-associated renal failure (one of the most common cause of death in intensive care units) had not been fully determined. The effect of nitric oxide and protein kinase C (PKC) pathways in isolated kidney of Lipopolysaccharide-treated (LPS) rats were investigated in this study. Materials and Methods: Vascular responsiveness to phenylephrine and acetylcholine...
متن کاملHistopathological effects of quercetin on liver tissue damage induced by iron oxide and iron oxide nanoparticles in Wistar rats
Introduction: Industrial and environmental pollution, excessive iron supplementation and blood transfusion are among the factors that may cause iron toxicity. Therefore, it is necessary to identify the mechanisms influencing or protecting against iron toxicity. The present study aimed to investigate the protective effects of quercetin as an antioxidant on hepatotoxicity induced by iron oxide an...
