                      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 labor and delivery

Prostaglandins are produced by almost every tissue in the body and serve as important messengers or effectors in a wide variety of functions. The pivotal role of prostaglandins in contraction of the smooth muscle of the uterus and the biophysical changes associated with cervical ripening, however, point to a major problem with their clinical use. According to the study of the role of prostaglandinsin labor and delivery by University of South Florida College of Medicine, found that unlike oxytocin which requires an induction of receptors that does not usually occur until the later part of pregnancy, prostaglandins receptors always are present in myometrial tissue. This allows for the use of prostaglandins in usual doses throughout pregnancy. Although both F and E series prostaglandins result in uterine contractions, E series prostaglandins are relatively more uteroselective and are clearly superior to F series prostaglandins in producing cervical ripening. Modification of the naturally occurring prostaglandins by blocking the sites that are affected during their usual rapid metabolism, results in products with much longer durations of action, efficacy at much lower concentrations, and a potential for significant savings in cost(2).
