[Biological testing of hemostatic properties of various collagen preparations].
In experiments on animals a method of studying electrostatic and hemostatic properties of collagens was worked out. Following hemostatic collagen sponges were used: Superstat (Interface Biomedical Laboratories Corporation, USA), Hemostatic Felt (B. Braun, BRD), collagen sponge and collagen foil (Central Tissue Bank of Transplantation Institute, Medical Academy, Warsaw). Biological experiments were performed on rabbits in 4 groups, depending of the implanted material. Basing on surgical macro- and microscopic evaluation it was found that collagen preparations used in the experiments shorten the duration of bleeding of damaged liver, and that biological reactivity of studied collagen preparations is proportional to the duration of their resorption time in tissues. The shortest resorption time gave the Superstat.
