title: [Role of splenin and its active factor in regulating liver monooxygenase system in experimental immunodeficiency and hepatosohepatitis].
abstract: An influence of splenin and its non-peptide factor of splenin (NFS) on the state of cytochrome P-450 dependent monooxygenase system (MOS) of liver microsomes in healthy animals under immunodeficiency (splenectomy, administration of gamma-aminobutyric acid (GABA) and toxic hepatosohepatitis was studied. The stimulating action of splenin and NFS on cytochrome P-450 content and MOS activity of liver microsomes in healthy animals has been established. The indices studied markedly decreased after splenectomy. The splenin or NFS administrations promote the recovery of these indices up to starting level in asplenic animals. A decrease in thymic mass dependent in GABA administration is prevented by NFS pretreatment of animals; there is no any effect of mediator acid on cytochrome P-450 content and MOS activity was noted. The preliminary administration NFS potentiates hepatotoxic effect of carbon tetrachloride and increases its inhibitory effect on P-450 dependent MOS of liver microsomes. Under the NFS action the effect in activity of the last is caused by the factor influence on the reparative processes in the liver.
