Objective(s): The purpose of this study was to detect the protective effects of adiponectin on coagulation dysfunction and its mechanism in sepsis of rats.
Materials and Methods: The experimental samples were composed of sham group,   model group that was underwent cecal ligation and puncture (CLP) and three adiponectin treatment groups that treated by adiponectin with different dose (72 μg/kg, 96 μg/kg and 120 μg/kg) after CLP. The prothrombin time (PT), activated partial thromboplastin time (APTT) was measured, respectively, the level of malondialdehyde (MDA), tissue factor (TF), activated coagulation factor VIIa and Xa, p-selectin were detected, the histology structure of vascular was observed, the expressions of Caspase 9, Caspase 3, Bax, Bcl-2 and vWF in vascular were measured.
Results: The results demonstrated that adiponectin treatment lengthened PT and APTT, reduced the expression of MDA, TF, activated coagulation factor VIIa, Xa and p-selectin in plasma of septic rats. Additionally, adiponectin treatment alleviated endothelial cell apoptosis and oxidative stress, down-regulated the levels of Caspase 3, Caspase 9, Bax, Bcl-2 and vWF in vascular.
Conclusion: These findings suggest that adiponectin treatment might be a promising therapeutic strategy for relieving septic endothelial cell injury and coagulation dysfunction via inhibiting endothelial cell apoptosis in septic rats.
