“…With the premature discharge of amniotic fluid, 20-25 percent of women develop a violation of the contractile activity of the uterus, which is manifested by weakness, which requires not only the use of uterotonics but also fetal distress increases the percentage of cesarean section [3].…”

“…При передчасному вилитті навколоплідних вод у 20 -25 відсотків жінок розвивається порушення скоротливої діяльності матки, яке проявляється слабкістю, що потребує не тільки застосування утеротоніків, але і дистрес плода збільшує відсоток кесарського розтину [3].…”

“…This disease mainly affects the able-bodied population, reduces social activity, affects work capacity and significantly worsens the quality of life [1]. Available data indicate that urticaria significantly affects objective functioning and subjective well-being [2][3][4]. There are literature data that indicate that the indicators of the quality of life of patients with chronic urticaria can be compared with those of patients with coronary heart disease [5].…”

Histological preparations were prepared. The slides were stained with hematoxylin-eosin and Van Gieson's stain.Results of the study. Microscopic examination of the extraplacental tissues of the afterbirth, which are represented by three membranes -amniotic, chorionic and intimate adjacent decidual, in case of premature amniotic fluid discharge is characterized by heterogeneity of structure. Thus, in contrast to the membranes in case of timely amniotic fluid discharge, in case of premature rupture of the membranes at their edge, there is a pronounced swelling of all elements of the membranes.Destruction of epithelial cells and their degenerative changes were observed in the amnion. There was no clear boundary between the amnion and the smooth chorion. In many preparations, with premature amniotic fluid discharge and an increase in the anhydrous interval of more than 8 hours, dystrophic changes in the epithelium, expressed transformations into a continuous cuticular cluster, were noted.In case of premature amniotic fluid discharge, focal, and less often diffuse infiltration with segmented leukocytes was detected in the membranes. It was detected in the decidual layer of the periepithelial membranes during a prolonged waterless period of more than 6-8 hours.Thus, a prolonged waterless period is not always accompanied by leukocyte infiltration of the parietal membranes. However, with an increase in the water-free interval of more than 6 hours, the first manifestations of parietal deciduitis may appear, and after 8 hours -chorioamnionitis. These data are consistent with the results of our simultaneous bacteriological studies.Conclusions. The detected changes in the amnion and chorion, with a minimal anhydrous interval, are characterized by destruction of epithelial cells, degenerative changes, lack of a clear boundary between the amnion and chorion, changes in the intercellular space, swelling.

Connection of the publication with planned research works.The work is a fragment of SRW "Pathogenetic role of endothelial dysfunction and genetic features in pathology during pregnancy and gynecological diseases", state registration number 0117U005253. Introduction.Complex chemical, physical and biological properties of an amniotic fluid determine the nature of the external environment and hemostasis of the fetus. At certain stages of development, amniotic fluid participates in the fetus's nutrition, contributing to the development of the respiratory tract, the function of the kidneys and the skin of the fetus. At the same time, the exchange rate of amniotic fluid is important, in the process of which there is an influx of substances necessary for the development of the fetus and the removal of metabolic products that are subject to removal [1,2].Amnion and smooth chorion have morpho-functional signs of active participation in metabolism and creation of conditions for the development of pregnancy. The vascular network and biochemical processes in the decidual membrane also play a significant role in metabolism. In addition, membranes play a major role in the placental exchange between mother and fetus along with transplants. Placental metabolism is primarily determined by the structure of the fetal membranes and
