Moreover, the concomitant increase in oxidation of cortisol to cortisone within the fetus could act, in concert with increased placental oxidation of maternal stores, to ensure continued synthesis and release of ACTH by the fetal pituitary gland. There are so few data available for the lipoxygenase compounds in association with pregnancy and labor that one can only speculate as to their physiologic functions.

Fetal hypophysectomy or adrenalectomy results in a prolongation of gestation in sheep, whereas fetal ACTH or glucocorticoid infusion results in premature labor. In women with preeclampsia, low-dose aspirin therapy decreases systolic, diastolic, and mean blood pressures. The initial report based on intent to treat of the NICHD Maternal—Fetal Medicine Unit Network trial of low-dose aspirin to prevent preeclampsia in nulliparous women found a modest reduction in the incidence of preeclampsia from 6.nato order of battle V The original document, including many of the orbats and the forward was prepared by Andy Johnson, to whom I owe a great debt of gratitude for preparing the original document.
