THE ROLE OF THE CHANGED PRODUCTION OF INTRACELLULAR REGULATORS IN PATHOGENESIS OF PRETERM DELIVERY

Purpose: To determine the influence of the changed production of bioactive components on the trophoblast invasion disorders and as a result development of preterm delivery.Materials and methods: 69 pregnant women were under observation, among them there were 48 women with the threatened miscarriage in the 1st trimester and preterm delivery and 21 women with physiological gestation. The determination of the content of glycodelin-A, follistatin, IL-1β and TNF-α in the blood serum during the 1st trimester and in case of preterm delivery in the 34th - 37th weeks was realized by means of immunoenzyme method.Results: An evident imbalance of intracellular bioregulators that determine nidation of the ovum and chorion formation was revealed.Summary: A high level of TNF-α causes the disorder of calcium ion concentration in myometrium cells that leads to initiation of preterm delivery.
