  • Title: [Metabolism of xenobiotics in the liver in acute hypoxia of intact mice and mice adapted to oxygen deficiency].
    Author: Grek OR, Dolgov AV, Iziumov EG, Loktev VB.
    Journal: Farmakol Toksikol; 1984; 47(1):98-101. PubMed ID: 6705909.
    Abstract:
    Experiments on white mice were made to study the effect of acute hypoxia in intact and hypoxia adapted animals on the function of liver hydroxylases. It was shown that acute hypoxia (vacuum 462 Pa, exposure 120 min) leads to a decrease in the rate of amidopyrine demethylation by liver microsomal enzymes. Preadaptation to hypoxia reduces the depth of microsomal hydroxylation inhibition in response to hypoxia. Variation in the constant of substrate binding with the enzymatic complex plays in important role in the mechanism of microsomal oxidation inhibition in the liver under hypoxia. The concentration of the hemoproteins P = 450 and b5 does not undergo any substantial changes.
