Abstract For the purpose of studying the effects on wound healing of three new bioelectret composites (BC) which are composed ofcollagen polyvinyl alcohol and epidermal growth factor (EGF), 30 rabbits were divided into 5 groups. Three wounds in round shape (1.8 cm in diameter) were made in each side of the back of the rabbits. The wounds of 1～3 groups were treated by one of the three BC respectively, group 4 treated by SDAg, and group 5 were treated by Normal saline as control. From observation of the growth of the granulation tissue, the reepithelization and the pathological assessment, it was shown that the quality of wound healing in all BC treated wounds was better than that in SDAg or the control. It indicated that the BC benefited the wound healing, and this might also be due to its bioelectric effects and the direct effects from growth factor.
