Thrombus formation in blood vessel plays an important role in the pathogenesis and progression of atherosclerosis and cardiovascular diseases. Extract of Dioscorea zingiberensis C.H. Wright (D. zingiberensis) is demonstrated to posses activities for curing cardiovascular diseases such as coronary heart disease and angina pectoris. However, there were few studies on anti-thrombosis activity of it. We investigated the anti-thrombosis effect of diosgenin from D. zingiberensis (Dio) in vitro and in vivo on inferior vena cava ligation thrombosis rat model and pulmonary thrombosis mice model. We evaluated the protective effect of Dio by measuring the platelet aggregation, activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT) and the venous thrombosis in rats and the bleeding time, clotting time and protection rate in mice. Results showed that Dio inhibited platelet aggregation, thrombosis and prolonged APTT, PT and TT in rats in a dose-dependent manner. They also prolonged the bleeding time, clotting time and increased protection rate in mice in a dose-dependent manner. Taken together, these findings suggested that Dio which contained 95% diosgenin had anti-thrombosis activity. Dio executives the ant...Continue Reading

Cardiac Glycosides

Cardiac glycosides are a diverse family of naturally derived compounds that bind to and inhibit na+/k+-atpase. Discover the latest research on cardiac glycosides heres.

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.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
