| 摘 要： | 目的 探讨皮肤扩张术（Ｓｋｉｎ ｅｘｐａｎｓｉｏｎ ｔｅｃｈｎｉｑｕｄｅ，ＳＥＴ）的机理。方法 以家犬为动物模型，应用显微分光光度计及放射微球技术，对扩张后皮肤表皮有丝分裂及皮瓣微循环进行了测定。结果 （１）被扩皮肤表皮明显增厚；（２）基底细胞有丝分裂较对照组显著增强；（３）皮瓣微循环较即刻皮瓣显著增强。结论 （１）ＳＥＴ并非仅以代偿为基础，而复制了新的“剩余”皮肤。（２）增强了皮瓣微循环，增大皮

| Abstract: | OBJECTIVE: In order to explore the mechanism of skin expansion technique (SET). METHODS: Domestic dogs were used in this experiment. The epidermal mitotic activity, capillary blood flow change of the expanded flap were observed with microspectrophotometer and radioactive microsphere technique. RESULTS: 1. The epidermis of expanded skin was significantly thicker than that of other groups (P < 0.05). 2. The epidermal mitotic activity was elevated significantly(P < 0.01). 3. The capillary blood flow of expanded flaps increased significantly (P < 0.01). CONCLUSIONS: 1. The surplus skin produced by SET is the result of replication, not compensation. 2. SET increases skin blood flow, therefore enlarges the survival area of an expanded flap. |
