Morphological features of placentas in weight deficient puerperants and their influence on a fetus (Message I)

Morphological features of placentas were investigated in practically healthy puerperants (12) and women with weight deficient (19) in a case of urgent delivery. In 30% of placentas in control group pathologic immaturity coupling with dissociated development (40%) were seen, which were, combined with slight involutiv-dystrophic processes (IDP) and maximal realization of compensatory processes in placentas that promotes delivery of healthy neo-nates with normal body weight. In a case of weight deficiency in mothers, significant IDP can be seen together with large amount of immature (63.2%) and dissociated (21%) placentas, suppression of compensatory processes with starting of mechanisms characteristic for embryonal period of development, which promotes delivery of alive neonates but with small for gestational age body weight and high rate of cerebral blood flow disturbances. The listed features are results of the influence of climate-geographical, ecological and social-economic live conditions of women in Tajikistan.
