[Regeneration of white rat liver during cholestasis].
Cholestasis inhibits expression of early response genes in rat hepatocytes stimulated to proliferation and restricts the process related to reparative regeneration. The occlusion of general bile duct induces bile acid accumulation, which suppresses 11-beta-hydroxysteroid-dehydrogenase activity. Hence, the concentration of corticosterone is increased, which suppresses the expression of early response genes in rat hepatocytes. The restoration of liver mass occurs due to proliferation of reserved cells. An unusual mitotic peak of these cells is registered 34 h after the operation.
