[Placental ultrastructure in women with impaired glucose tolerance during pregnancy]. / Ul'trastruktura platsenty zhenshchin s narusheniem tolerantnosti k gliukoze vo vremia beremennosti.

The principal distinctions were signs appearing at the subcellular level of slower trophoblastic maturation and enhancement of the active forms of placental transport function at the end of pregnancy. Changes of placental ultrastructure cannot be regarded as specific for diabetes mellitus, for they may be observed in other pathologic conditions of the mother and fetus as well and are probably related to trophoblast hypoxia.
