Comparison of freeze dried human amniotic membrane and its combination with platelet rich fibrin for the epithelial acceleration in an acute wound excision using Rattus Novergicus study model

Introduction: Human amniotic membrane and platelet rich fibrin (PRF) are biological materials that can accelerate wound healing through their content of growth factors and cytokines. This study aimed to determine the effectiveness of the combination of these two biological agents for wound healing. Methods: This study used an experimental method with a randomized post-test only control group design, to compare the use of human amniotic membrane alone with a combination of human amniotic membrane and PRF in acute full thickness wounds of the skin of Wistar rats. The research subjects were 32 rats which were divided into four groups. Groups 1 and 2 used human amniotic membrane, while groups 3 and 4 used a combination of human amniotic membrane and PRF, then the epithelialization process was observed on the 3rd and 6th day. Result: There was no statistically significant difference in the speed of epithelialization of excision wounds on the backs of rats on the third day (Significance 0.498) and Sixth (Significance 0.9) between the Amnion group and the combination of amnion and PRF because it was greater than α = 0.05. Conclusion: The use of a combination of freeze dried human amniotic membrane and platelet rich fibrin was not significantly more effective than freeze dried human amniotic membrane in accelerating the epithelialization of acute full thickness excision wounds in rats (Rattus novergicus).
