Abstract:
[Objective]To study the influence of VAP(velvet antler polypeptide)-chitosan-honey suspension on decubitus ulcer.[Method]Swines'pressure ulcers were used as decubitus ulcer model.Honey was used as solvent carrier.VAP and chitosan were put into the honey in different proportion.The suspension was applied to the ulcer once a day for seven days.The dressings were changed once every other day.The healing state of the ulcer was observed and the area of the ulcer was calculated.The changes of the ulcer histopathology were observed.[Result]In the group of the suspension proportion of the VAP to the chitosan was 4:1,the wounds had little effusion and the granulation tissues grew fast with the scars falling off early and Absolutely.Pathology results indicated that in the group of the suspension proportion of the VAP to chitosan was 4:1,none necrosis was found,the epithelization was apparent,and the inflammatory cells were fewer.There was no edema,but more newly born blood vessles.[Conclusion]The VAP-chitosan-honey suspension could apparently promote the healing of decubitus ulcer,but the possible mechanism needs to be further studied.
