제목 Accelerate Wound Healing in Hyperglycemia by Injectable Gallic Acid - Conjugated Chitosan Hydrogel
초록 The impaired wound healing in diabetes is one of the major challenges in healthcare presently. The development of a hydrogel which can accelerate the wound healing process in hyperglycemia is believed to bring sufficient benefit. In this study, gallic acid (GA) was conjugated on chitosan (CS) backbone: (1) To supply the reactive sites for gelation through HRP/H2O2 catalysis and (2) enhance the wound healing in hyperglycemia. Chitosan-gallic acid (CGA) conjugates were synthesized via EDC/NHS coupling reaction. The gelation and mechanical strength of hydrogel can be controlled by varying the HRP and H2O2 concentration. CGA hydrogel showed superior scavenging effect toward DPPH, OH. radical and H2O2. CGA also enhanced the migration of hDFBs in hyperglycemia. In conclusion, CGA hydrogel is expected to effectively use in supporting the diabetic wound healing by debilitating the oxidation stress. Acknowledgement: NRF-2018R1A2B2004529, 2018M3A9B5021319
