Abstract:
Objective: To study the change of placental corticotropin releasing hormone level in pregnant women entering spontaneous labor at term and preterm or posterm,and to investigate the value of CRH as an indicator of preterm labor. Methods: Subjects( n =200) were recruited to the study at their antenatal visits,and plasma samples were obtained at their routine antental clinic visits from 28 weeks to parturition at 2 weeks intervals.CRH were measured by radioimmunoassay. Results: CRH concentrations rose significantly as pregnancy developed and reached the highest level at delivery. Plasma CRH levels were significantly higher in preterm labor and lower in postterm labor after gestational 28 weeks( P
