The evaluation of serum prolactin concentrations in pregnant women threatened by preterm delivery.

Pregnancy is such a state in woman's life during which many changes appear in her organism. They are induced by the placental presence and function, fetal life and mother-fetus exchange. However, not always the course of pregnancy is correct and ends on time with the delivery of a healthy newborn. Thus, the medical and social significance of preterm delivery and connected with it prematurity and perinatal morbidity constitute the basis for prophylaxis, treatment and the search for various possible causes of that pathologic state.
