[Animal experiment studies of amnion transplantation as peritoneal replacement].

In view of the favorable properties of the amniotic membranes as a peritoneal substitute, the following questions were posed: (1) Can the vitality of the amniotic epithelium be preserved by cryoconservation? (2) Which reactive changes occur in an intraabdominal amniotic graft? Animal studies gave the following findings. The vitality of the amniotic cells was not impaired by cryoconservation. A histiocytic demarcation zone developed on the membrane.
