Decreased mitochondrial fatty acid oxidation in placentas from women with preeclampsia.

abstract：:Placentae from normal term pregnancies, from "normal" preterm pregnancies and from pregnancies complicated by pre-eclampsia have been analysed by computerized histometry. An immunoperoxidase technique was used to stain specifically human placental lactogen in the syncytiotrophoblast. The percentage and mass of syncyti...
