title: Prostaglandin synthesis in decidual tissue of the rate uterus.
abstract: Prostaglandin (PG) synthetase activity and tissue concentration were measured in unilateral deciduomata induced by traumatization of the pseudo-pregnant rat uterus and in the decidua of pregnancy. PG synthetase activity per unit weight of deciduoma tissue was 7-10 fold higher, throughout the life-span of the deciduoma, than that in the untraumatized control horn. The concentration of prostaglandins of the E-type in the deciduoma exceeded that found in the control uterine horn by a factor of 10-20 on days 3-4 after decidual induction, and about five-fold on days 9-10. The concentration of prostaglandins of the F-type in the deciduoma measured on days 4 and 8 did not differ significantly from that in the control horn.
