Abstract
Die hohe Anzahl der heutzutage angebotenen Verbandstoffe sowie der wissenschaftlichen Beiträge darüber weisen darauf hin, daß das Problem eines idealen Wundverbandstoffes noch nicht gelöst wurde. In den letzten 30 Jahren wurde wiederholt über eine wundheilungsfördernde Wirkung von Kollagen berichtet. Wir untersuchten ein nichtlösliches Rinderkollagen, das in Form eines Schwammes rekonstituiert wurde, in bezug auf die Heilung eines tiefen Hautdefektes bei Ratten. Zur Anwendung kamen dabei ein unvernetzter und ein chemisch vernetzter Kollagenschwamm. Die Ergebnisse der Wundheilung verglichen wir mit denen einer Kontrollgruppe ohne Wundverband und einer anderen, in der wir die Wunden mit Paraffingaze bedeckten. Die mit Kollagenschwamm bedeckten Wunden heilten schneller und qualitativ besser als die Kontrollwunden. The high number of available wound dressings as well as the scientific reports about this topic indicates that the problem of an ideal wound dressing material is not jet solved. In the last 30 years lot of scientific reports about collagen as wound covering has been published. The positive effect of collagen by this application on a wound is well-known. We investigated the effect of a collagen sponge on healing of full tickness wound in rats. The animals were divided in two control and two experimental groups. In the control groups there were air exposed wounds as well as wounds covered with paraffin gauze. In the experimental groups the wounds were covered with natural reconstituted collagen sponge as well as with chemically prepared sponge. All results were compared. The wounds with collagen sponge covering healed significantly faster. Also the quality of the wound healing was better in the experimental groups.Keywords
