创伤愈合中表皮再生机理的研究──Ⅰ人创面肉芽的光镜电镜观察

Mechanism of Epidermal Regeneration during Wound Healing(Ⅰ).Light and Electronic Mi-croscopic Observations on Human Wound Granulation

本文从患者创面切取健康肉芽及不良肉芽（水肿性及弛缓性），观察其显微及超微结构。实验结果表明水肿性及弛缓性肉芽的成纤维细胞变性、坏死、新生毛细血管发育不良．这可能是影响表皮再生的重要因素。

Healthy granulation tissue,edematous granulation tissue and flaccid granulation tissue from various patients' wounds were taken and their microstructures and ultrastructures observed,The results indicate that in edematous granulation tissue and flaccid granulation tissue both fibroblasts and collagenous fibers are generated and necrotic;neogenerative capillaries show dysplasia. These phenofnena may be important factors influencing epidermal regeneration.
