[Morphofunctional characteristics of the placenta of women living in extreme conditions of the Aral cost line].

Morphologic examination of the placenta from 41 puerperants living near the Aral sea revealed an increase of its mass and changes in other parameters. The detected pathologic processes: hemodynamic disorders and dystrophic changes--are not specific and contribute to the development of placental insufficiency. The majority (85.6%) of newborns were born in asphyxia. Morphofunctional features of the placentas of multiparous women and the status of their children permit regarding this population as the best adapted to pregnancy and delivery of viable children under the said extreme conditions.
