Platelet rich plasma transforms exogenous prostaglandin endoperoxide H2 into thromboxane A2
Abstract:
Platelet rich plasma transforms exogenous prostaglandin endoperoxide H2 into thromboxane A2 immediately prior to the initiation of irreversible aggregation. Selective thromboxane synthetase inhibitors block thromboxane A2 formation and aggregation. Thromboxane A2 formation appears to be essential during arachidonate mediated aggregation. The results presented reconcile the previously accepted paradoxical behavior of thromboxane synthetase in platelet rich plasma toward the prostaglandin endoperoxide H2 substrate.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
