Morphologic study of changes of collagenous tissue in the amnion and cervix during prostaglandin-induced abortion and delivery.

abstract：OBJECTIVE:We determined developmental and labor-related changes in 11beta-hydroxysteroid (HSD) 1 and 2 expression in baboon placentas during the final third of gestation and labor. We examined whether maternal glucocorticoid administration alters placental 11beta-HSD 2 expression. STUDY DESIGN:Maternal and fetal plasm...
