Abstract:
Objective To study the levels of umbilical plasma ?-endorphin (?-EP) in normal and abnormal pregnancy and the influencing factors. Methods The umbilical plasma ?-EP concentrations of 95 cases were measured by radioimmunoassay. Linear regression was used to find out the influencing factors of ?-EP including: neonatal gestational age, gender, birth weight, mode of delivery, maternal hypertension, maternal diabetes, premature rupture of membranes(PROM) and fetal distress. The subjects were divided into two groups: healthy term newborns and preterm neonates. Results Gestational age, mode of delivery and fetal distress were important factors influencing umbilical blood ?-EP production (P
