title: [Cytochrome P-450-dependent hydroxylation and activity of glutathione-dependent liver enzymes in chronic liver diseases].
abstract: Repression of cytochrom P-450-dependent hydroxylation and demethylation in liver was demonstrated in bioptats of patients with chronic liver diseases. The inhibition of cytochrome P450 system was provoked by oxidative modification of proteins-enzymes in patients with chronic liver changes as was proposed at the same time. The activation of glutathione-dependent enzymes was revealed. So the intensification of conjugation and development processes was revealed as the compensation mechanisms of detoxication with chronic liver diseases.
