    32P-postlabelling and PAH-ELISA were employed to analyze DNA adducts in venous and umbilical cord blood and the placenta of 79 mothers giving birth to 80 living babies in Prague (Czech Republic). Our results suggest a protective effect of the placental barrier against the genotoxic effect of some tobacco smoke components between the circulation of mother and child. We found a correlation between adduct levels in the blood of mothers and newborns.

    Metody 32P-postlabelling a PAH-ELISA byly použity k analýze DNA aduktů v žilní a pupečníkové krvi a placentě 79 matek, které porodily živé dítě v Praze. Naše výsledky ukazují na ochranný účinek transplacentární bariéry proti genotoxickému účinku některých látek v tabákovém kouři mezi krevním oběhem matky a dítěte. Byla nalezena korelace mezi hladinami aduktů v krvi matek a novorozenců.
