title: [Phagocytic activity and reproduction of the trophoblast cells in the embryo of albino rat].
abstract: The phagocytic activity of primary and secondary giant cells of the white rat's trophoblast was studied in the course of differentiation. The highest activity occurs in the initial period of the foetus implantation to last within a limited time for 5--6 days. Both quantitative and qualitative differences were detected in phagocytic activities of the trophoblast cells during their growth. A question is discussed of the time synchronism between the phagocytic activity and the trophoblast cells polyploidization.
