title: [Kinetic features of a white rat hepatocyte population under hormonal disbalance before and after partial hepatectomy].
abstract: Bilateral adrenalectomy, followed in 4 days by a partial hepatectomy, was performed using white rats weighing as much as 120-140 g. Under hormonal disbalance caused by bilateral adrenalectomy, the number of polyploid (4c, 4c x 2, and 8c) hepatocytes significantly increased, compared to that in non-operated control rats. Six hours after a partial hepatectomy, the share of highly ploid hepatocytes falls, being accompanied by a 9-fold increase in mitotic index. It is supposed that under hormonal disbalance condition, a partial hepatectomy may induce "early" mitoses in hepatocytes blocked in G2-phase of the cell cycle.
