  • Title: [6-keto-prostaglandin F1 alpha and thromboxane B2 in the amniotic fluid and peripheral venous blood in healthy pregnant patients and in pregnant patients with pre-eclampsia].
    Author: Nieder J, Augustin W.
    Journal: Zentralbl Gynakol; 1987; 109(23):1422-7. PubMed ID: 3442151.
    Abstract:
    In order to characterize the prostacyclin and thromboxane system during gestosis the stable degradation products 6-keto-prostaglandin F1 alpha (6-keto-PG F1 alpha) and thromboxane B2 (TX B2) have been determined by radioimmunoassay in amniotic fluid and maternal venous plasma from 16 normotensive pregnant women and 14 patients with preeclampsia. At preeclampsia as well in amniotic fluid as in plasma a tendency towards lowered levels of 6-keto-PG F1 alpha and at the same time increased levels of TX B2 may be visualized. In the plasma generally significant higher levels of both 6-keto-PG F1 alpha and TX B2 than in amniotic fluid have been established. The imbalance between anti-aggregatory and vasodilatatory prostacyclin and proaggregatory and vasoconstrictory thromboxane in preeclampsia is indicated by an increase of the ratio TX B2/6-keto-PG F1 alpha from 1.38 to 2.44 in amniotic fluid and from 1.88 to 2.81 in plasma.
