Abstract

It is not yet clear what exact mechanisms are at work in hibernating animals that prevent clot formation and maintain tissue perfusion under conditions of very slow blood flow and increased blood viscosity brought about by the low temperatures. It has been shown that the total amino acid pool increases more then two fold in hibernating animals with taurine accounting for about 50% of this increase [Storey et al., Proc Natl Acad Sci USA 1988; 85(21): 8350-4]. This work investigates the effect of taurine on platelets and the plasma coagulation system. Taurine was added at different concentrations in the range between 5 and 25 mM to donor plasma. Using STA/STA Compact coagulation analyzer the following tests were performed: prothrombin time (PT), activated partial thromboplastin time (APTT), and thrombin time (TT). At the highest concentration tested (25 mM) taurine prolonged TT by 9%. The prolongation was statistically significant but not clinically significant retaining TT within normal limits (16.7-20.7 s). PT and APTT remained unchanged by taurine. The effect of taurine on platelets was assessed by platelet aggregation by thrombin, extent of platelet shape change (ESC) induced by ADP, and thrombelastography. Taurine at 5 mM fi...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.
