                      Hormone Prostaglandins

Prostaglandins, are a group of lipid mediators, found and isolated from human semen in the 1930s by Ulf von Euler of Sweden, responsible for inflammation features, such as swelling, pain, stiffness, redness and warmth. The hormones are produced by almost all nucleated cells and synthesized in the cell from the essential fatty acids (EFAs), include prostacyclin I2 (PGI2), prostaglandin E2(PGE2), and prostaglandin F2α (PGF2α)

     Hormone Prostaglandins  in platelet aggregation

Prostaglandins which are derivatives of arachidonic acid including prostaglandin, endoperoxides, thromboxane A2, prostaglandin E2, prostaglandin D2 and prostacyclin. may induce or inhibit platelet aggregation and constrict ro dilate bloodvessels. According to the study by Dr. Smith JB., it exacerbates ischaemic damage because of a selective increase in vascular resistance due to coronary vasospasm and platelet aggregation which acts to decrease myocardial blood flow. The stable prostaglandins PGD2 and PGE2 are also of interest as both are formed during platelet aggregation. Like PGI2, PGD2 inhibits platelet aggregation(13).
