[Chorionic epithelium in the resorption-villi of placentas of hypotrophic term-born infants. Morphology in chronic placental insufficiency]

Abstract

The chorionic epithel of 61 placentas of hypotrophic term-born (small for date) with or without the sign of dysmaturity will be compared with the chorionic epithel of 25 placentas of eutrophic term-borns after clinical and anamnestic normal pregnancy or enzym-incubated Cryostat- and semi-thin-slides. Different degrees of predegenerative plasmoditrophoblast by proliferation or persistence high differentiated and degenerated Langhanscells are signs of disturbed regeneration processes in chorionic epithel by chronical fetal malnutrition. This functional- morphological disturbance of villous trophoblast low-weighted newborns will be evaluated as a morphological correlat by chronical insufficiency of placenta. The possible connections with functional capacity of chorionic epithel will be discussed.
