Abstract

The present study was designed to investigate the antithrombotic effects and underlying mechanisms of the effective components group (ECG) of Xiaoshuantongluo recipe (XECG) and to further verify the rationality and feasibility of ECG-guided methodology in traditional Chinese medicine (TCM) research. The arterial thrombosis model induced by ferric chloride (FeCl3) oxidation and the venous thrombosis model induced by inferior vena cava ligation were established to evaluate the antithrombotic potential of XECG. Our results indicated that XECG significantly prolonged the time to occlusion, activated partial thromboplastin time (APTT), and prothrombin time (PT), and markedly inhibited adenosine diphosphate (ADP)-induced platelet aggregation in the 20% FeCl3-induced arterial thrombosis model. The superoxide dismutase (SOD) activity was significantly increased and the levels of malondialdehyde (MDA) and nitric oxide (NO) were dramatically decreased in the plasma of arterial thrombosis rats after XECG treatment for 12 days. Furthermore, XECG markedly reduced the weight of thrombus formed by inferior vena cava ligation. Additionally, XECG exhibited 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and protective effe...Continue Reading

Blood Coagulation Signaling Pathways

Coagulation is the process by which a blood clot is formed. This process includes both the formation of a platelet plug as well as a cascade of clotting factors resulting in the formation of fibrin strands. Find the latest research on coagulation signaling pathways here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
