LOPEZ-RAMIREZ, Ysabel; CARVAJAL, Zoila  and  AROCHA-PINANGO, Carmen Luisa. Hemostatic system parameters of placental extracts in normal pregnancy and severe preeclampsia. Invest. clín [online]. 2006, vol.47, n.3, pp.233-240. ISSN 0535-5133.

To better understand the role of the hemostatic mechanism in preeclampsia, placental extracts obtained from 26 normal pregnant women (NP) and 12 patients with severe pre-eclampsia (SPE) were analyzed to determine thrombomodulin (TM), tissue factor (TF), tissue-type plasminogen activator (tPA), plasminogen activator inhibitor (PAI) 1 and 2, and TF pathway inhibitor (TFPI). The results showed similar concentrations of TF, TM and PAI-2 in both groups, while tPA increased no significantly and TFPI and PAI-1 increased significantly in SPE placentas.

Keywords : Hemostatic parameters; placenta; preclampsia.
