Endothelin-1 levels in mothers with eclampsia--pre-eclampsia and their newborns

We examined concentrations of endothelin-1 in fetal and maternal plasma samples during hypertensive and normotensive pregnancies. There were significant differences between endothelin-1 levels of eclamptic-preeclamptic mothers' newborns and healthy preterm infants (P < 0.001), but there was no significant difference between endothelin-1 levels of healthy term and preterm infants (P > 0.05).
