title: [Effect of rat liver chalones on liver cell proliferation at different times after partial hepatectomy].
abstract: The action of rat's liver ethanol extract (72--81 per cent saturation) on cell proliferation of this organ at various periods after a partial hepatectomy has been studied. The most sensitive periods of the action of G1- and G2-chalone were, resp., the time of cell transformation, and the middle of the premitotic period of cell cycle. The action of G2-chalone used is organ-specific, since the drug decreased the mitotic activity of both hepatocytes and stromal cells. At the same time, the proliferation of ear, tongue and small bowel epithelial cells remained unchanged.
