title: [The effect of reversible ischemia of the rat liver on antipyrine metabolism and the isoenzyme activity of cytochrome P-450].
abstract: The character of changes in the metabolism of antipyrine, etoxy-, methoxy- and pentoxyresurphin after total reversible ischemia of the liver was studied in rats. In animals highly resistant to hypoxia the metabolism of xenobiotics specific to cytochromes P-450 IA1, IA2, and IIB1 was inhibited; in subjects with low resistance to hypoxia only P-450 and IA1 activity was suppressed while the activity of P-450 IIB1 and IA2 increased 2-3-fold.
