Abstract
The aim of the present study was to clarify the effect of recombinant human erythropoietin (EPO) and low molecular weight heparin (LMWH) on a rat model of lipopolysaccharide (LPS)-induced disseminated intravascular coagulation (DIC). Experimental DIC was induced by sustained infusion of 5 mg/kg LPS for 4 h. EPO or LMWH was then administered to the LPS-induced DIC model. LPS-induced consumption coagulopathy, hemostatic activation and plasma TNF elevation remained unaltered in the LPS+EPO group, except for the D-dimer levels, and these abnormalities were significantly improved in the LPS+LMWH group. Plasma alanine aminotransferase (ALT) levels were markedly reduced in the LPS+EPO group, accompanied by a significant suppression of hepatocellular apoptosis. In the LPS+LMWH group, plasma creatinine levels and glomerular fibrin deposition were significantly attenuated, along with plasma ALT levels and hepatocellular apoptosis. Thus, a single administration of EPO may improve hepatic dysfunction by primarily exerting an anti-apoptotic, not anticoagulant, effect in the LPS-induced DIC model.
