[P-selectin as endothelial reactivity marker in patients with pre-eclampsia].

Introduction: Pre-eclampsia affects 5% of all pregnancies. The physiopathologic hallmark is altered endothelium function and platelet activation. Selectins are molecules involved with the regulation between these systems, P-selectin is a molecule expressed in platelet membrane.

[IgM antiphospholipical antibodies in preeclampsia-eclampsia].

Background: Antiphospholipid antibodies are associated with thrombocytopenia and fetal loss, and have been reported elevated in patients with preeclampsia-eclampsia. Site: Preeclampsia-Eclampsia Research Unit, Instituto Materno Infantil del Estado de Mexico, Toluca, Mexico and the Specialty Hospital Research Unit, La Raza Medical Center, Mexico City, Mexico.

Objective: To determine the presence of anticardiolipin antibodies (IgG-IgM) as markers of acute endothelial damage in patients with preeclampsia.
