[Detection of prostaglandins from decidua (author's transl)].

PGE2 and PGF2 alpha were isolated from the decidua of an early pregnancy, following medical termination. The biosynthetic capacity for 6-keto-F1 alpha was tested by incubation, using 3H-labelled arachidonic acid. Prostaglandin concentrations in the decidua differed strongly from steroid hormones in plasma. Steroid hormone concentrations increased with continuity, whereas prostaglandin values remained extremely low.
