title: [Absorption of chitosan applied to polyester discs in rats after implantation].
abstract: Experiments have been made on white rats implanting polyester blocks covered with chitosan into the peritoneal cavity and to the abdominal wall skin. Before implantation the material was sterilized with ethylene oxide or radiation. The animals were subjected to autopsy 3, 7, 14, 21, 25, 30, 35, 40, 45, 50, 55 and 60 days after implantation with macroscopic and microscopic evaluation. On the basis of the carried out experiments it was stated that the disintegration of chitosan proceeded not uniformly. The resorption time of chitosan oscillated in the range of 45-60 days and it was accompanied by rather strong specific inflammation process. It was characterized with fibrin effusion and with appearance of multi-flapped neutrocytes. Essential distinctions in the resorption process of depending on the sterilization mean of the blocks as well as on the place of implantation were not stated.
