  • Title: Effects of prenatal and postnatal exposure of rats to alcohol: changes in (Na+-K+) ATPase.
    Author: Guerri C, Grisolía S.
    Journal: Pharmacol Biochem Behav; 1982 Nov; 17(5):927-32. PubMed ID: 6294687.
    Abstract:
    Maternal ethanol consumption produces a reduction in postnatal growth. We have studied especially changes of liver and brain. This reduction is more marked if the alcoholic offspring are maintained with their biological mothers than if they are kept with surrogate mothers. Rats exposed prenatally to alcohol show a marked accumulation of fat in the liver and a significant proliferation of liver endoplasmic reticulum. No change in the postnatal development of liver alcohol (ADH) and acetaldehyde dehydrogenases (ALDH) (high and low Km) is observed in offspring from alcoholic mothers, with the exception of slightly higher ALDH (low Km) for the offspring that remain with alcoholic mothers. The postnatal development of the liver (Na+-K+) ATPase is also similar in control and alcoholic groups. However, in the case of the enzyme from the brain, a lower ATPase activity is observed in the group derived from alcoholic mothers. Interestingly, at 20 days of postnatal period, an induction of the ATPase (from liver and brain) was observed when the group of offspring from alcoholic mothers were kept on an alcohol diet.
