[Dependence of mononuclear infiltration of the liver on hepatocyte proliferation].
Partial liver resection (two-thirds) performed in (CBA X C57BL)F1 mice 2-4 or 24 h after intravenous injection of 2 mg zymozan led to retardation of the formation of mononuclear infiltrates in the liver and the lung. In control sham-operated animals, the first signs of infiltration appeared on the 2nd, whereas in mice with partial liver resection ( PLR ) on the 5th day after zymozan -induced stimulation of liver macrophages. If mice underwent PLR 5 days after zymozan injection, the preformed mononuclear infiltrates experienced the reverse development. PLR did not abolish monocytosis which was observed after zymozan injection. On the other hand, when mice received hydrocortisone in a dose of 125 mg/kg, the zymozan -induced infiltration in the liver as well as monocytosis were blocked. It is assumed that depression of mononuclear infiltration in the liver and the lung after liver resection is linked with a specific effect of proliferating hepatocytes rather than with the stress-induced mobilization of glucocorticoids.
