  • Title: The effect of ethanol consumption during gestation on maternal-fetal amino acid metabolism in the rat.
    Author: Lin GW.
    Journal: Curr Alcohol; 1981; 8():479-83. PubMed ID: 7343192.
    Abstract:
    The distribution of 14C-alpha-aminoisobutyric acid (AIB), administered intravenously, in maternal, fetal and placental tissues was examined in the rat on gestation-day 21. Ethanol consumption during gestation (day 6 through 21) significantly reduced the uptake of AIB by the placenta and fetus while exerting no influence on maternal tissue AIB uptake. The concentration of fetal plasma free histidine was decreased 50% as a result of maternal ethanol ingestion, but the free histidine level of maternal plasma was not altered. Since no effect on protein content of fetal tissue could be detected, it is speculated that reduced histidine to the fetus might significantly alter the amounts of histamine and carnosine formed via their precursor. The significance of these findings in relation to the Fetal Alcohol Syndrome is discussed.
