摘要
为了观察外源性表皮生长因子对创面愈合的影响，在３０例大鼠皮肤创面愈合模型中，局部外用表皮生长因子（ＥＧＦ），以软膏基质作为对照，分别于１，２周测量创面面积，测定创面组织中的ＤＮＡ、蛋白质及羟脯氨酸含量，记录创面完全愈合时间。结果表明，实验组与对照组创面完全愈合的时间分别为（１４．６±１．２）天和（１８．５±２．０６）天（Ｐ＜０．０１），ＥＧＦ能显著增加组织中的ＤＮＡ、蛋白质及羟脯氨酸含量（Ｐ＜０．０１）。结果提示，ＥＧＦ能显著加速创面的修复，缩短愈合时间。
In order to investigate the function of epidermal growth factor (EGF), the following experiments were performed. Thirty white rats were chosen and divided into 3 groups. In the back of each rat, two 2 cm×2 cm wounds were made bilaterally, the skin and subcutaneous tissue was removed. EGF were used in one of the two wounds randomly, while those without EGF usage in control. After 1,2 and 3 weeks, the rats were sacrificed. The area of the wounds was measured, and the healing time of each wound was recorded. The results showed that the healing time of EGF group was 14.6 days while that of control group was 18.5 days (P<0.01) . Furthermore, the DNA, protein and hydroxyproline contents of EGF group were higher than those of the control group (P<0.01). It was suggested the EGF could accelerate wound healing and shorten the healing time.
