Abstract:
Objective To develop chitosan composite keratinocyte growth factor-2 mutant(KGF-2M)temperature-sen-sitive dressing and evaluate its physicochemical properties and dynamic release rule were used.Methods Chitosan, chi-tosan quaternary ammonium salt,β-glycerophosphate and other adjuvant materials to configure different formulations which were compounded with KGF-2M in order to develop temperature-sensitive dressing.Gelling time, temperature,the release rate of KGF-2M and other indicators were measured to analyze the physical and chemical properties of the temperature -sen-sitive dressing.Results Chitosan-KGF-2M composite dressing with temperature-sensitive properties was obtained by opti-mizing the formulation components of chitosan and related adjuvant materials.When the liquid dressing was above 35℃,it could be converted from liquid to solid gelatin within 10 minutes.The compound KGF-2M released from the gel was more than 98%at 4 h,and its bioactivity remained stable.Conclusion The thermo-sensitive gel has the characteristics of good conformability,moisturizing(moisture),isolation,wound healing,and a controlled release effect,which has great potential in wartime for wound repair.
