上皮生长因子是一种53-氨基酸多肽,能促进多种细胞中的RNA、DNA和蛋白质的合成。它能在体外实验中刺激角化细胞分裂,于体内促进上皮再生。在实验动物部分深度烧伤和供皮区,它有明显促进上皮再生的作用。它还能影响间质细胞而显著促进部分深度烧伤的真皮再生及增加外科切口间张力。本实验旨在研究上皮生长因子对供皮区和受皮区愈合率的影响。 Epithelial growth factor is a 53-amino acid polypeptide that promotes the synthesis of RNA, DNA, and proteins in a variety of cells. It stimulates keratinocyte division in vitro and promotes epithelial regeneration in vivo. In the deep part of the experimental animal burn and the donor site, it has a significant role in promoting epithelial regeneration. It can also affect stromal cells and significantly promote dermal regeneration of partially deep burns and increase tension between surgical incisions. The purpose of this experiment was to study the effect of epithelial growth factor on the healing rate of the donor and recipient skin regions.
