We examined concentrations of endothelin-1 in fetal and maternal plasm
a samples during hypertensive and normotensive pregnancies. There were
significant differences between endothelin-1 levels of eclamptic-pree
clamptic mothers' newborns and healthy preterm infants (P < 0.001), bu
t there was no significant difference between endothelin-1 levels of h
ealthy term and preterm infants (P > 0.05).
