RESEARCH ON REDUCING PREMATURITY RUPTURE OF MEMBRANE
Abstract
The membranes surrounding the amniotic cavity are composed from amnion and chorion, tightly adherent layers which are composed of several cell types, including epithelial cells, trophoblasts cells and mesenchyme cells, embedded in a collagenous matrix. They retain amniotic fluid, secret substances into the amniotic fluid, as well as to the uterus and protect the fetus against upward infections from urogenital tract. Normally, the membranes it breaks during labor. Premature rupture of the amniotic sac (PRAS) is defined as rupture of membranes before the onset of labor. Premature rupture of the fetal membrane, which occurs before 37 weeks of gestation, usually, refers to preterm premature rupture of membranes. Despite advances in the care period, premature rupture of membranes and premature rupture of membranes preterm continue to be regarded as serious obstetric complications. On the term 8% - 10% of pregnant women have premature rupture of membranes; these women are at increased risk of intrauterine infections, where the interval between membrane rupture and expulsion is rolled-over. Premature rupture of membranes preterm occurs in approximately 1% of all pregnancies and is associated with 30% -40% of preterm births. Thus, it is important to identify the cause of pre-term birth (after less than 37 completed weeks of "gestation") and its complications, including respiratory distress syndrome, neonatal infection and intraventricular hemorrhage. Objectives: the development of the protocol of the clinical trial on patients with impending preterm birth, study clinical and statistical on the socio-demographic characteristics of patients with imminent preterm birth; clinical condition of patients and selection of cases that could benefit from the application of interventional therapy; preclinical investigation (biological and imaging) of patients with imminent preterm birth; the modality therapy; clinical investigation of the effectiveness of short-term (3 days) and distance (2 years) interventional methods applied; clinical investigation of complications arising post intervention; studying behavior synthetic amnion. Conclusions: The cause of PRAS is multifactorial. Traditionally, fetal membrane rupture has been attributed to increased physical stress, which weakens the membranes. At the molecular level PRAS is the result of reducing collagen synthesis, alteration of the structure of collagen to accelerate degradation. In addition, these biochemical changes can be amplified and biophysical stress today. The priorities of this research include elucidation of the normal biological process of fetal membranes, including extracellular matrix remodeling, apoptosis.
