摘要
用小猪皮提取胶原,与葡甘聚糖和硫酸软骨素复合改性制成复合膜,研究用于修复全层皮肤缺损. 选用新西兰大白兔14只,1.5～2.0 kg,在胸腰脊柱两侧切割建立2 cm×4 cm全层皮肤缺损模型,左侧为试验组,敷以复合膜,右侧不经任何处理,作为空白对照组.观察创面的变化,定期取材,作组织学检查. 复合膜有防止创口出血和感染的作用,实验组创伤愈合形成矩性痂,空白对照组形成线性痂.无明显的免疫排斥反应,有促进皮肤结构再生的能力.胶原-葡甘聚糖-硫酸软骨素复合膜对创伤的修复有促进作用.
This study aims at restoring the skin from traumatism by use of the collagen（from piglet skin） and konjac glucomannan-chondroitin sulfate blend film. The 2 cm × 4 cm skin traumatism model was established on both sides of the waist spinal column in 14 New Zealand rabbits each weighing 1.5-2.0 kg. One side was covered with blend film, the other side was used as a control. Then the changes of the skin traumatism were observed at different time-points after the operation, the wound tissue samples were taken for histological examination. The blend film could prevent skin traumatism from bleeding and infection. The skin traumatism treated by blend film showed signs of rectangle scab and the control showed signs of linear scab after healing. No obvious immune rejection was seen. The collagen-konjac glucomannan-chondroitin sulfate blend film can accelerate the restoration of skin from traumatism.
