大白鼠背部真皮下血管网皮瓣蒂部功能的研究

The supporting effects of the pedicle of the subdermal vascular network flap in the rat

目的探讨真皮下血管网皮瓣蒂部对皮瓣成活的作用。方法以大白鼠背部真皮下血管网皮瓣为主要研究对象,相同部位的真皮下血管网皮片为对照,设计皮瓣长宽比例为4:1。皮瓣及皮片采用肉眼观察及仪器两种观察手段。将实验动物分为条件不同的3组,以毛发生长为最重要的观察指标。结果对116只大白鼠进行的实验研究,表明各组皮瓣的近端1/4生长良好。结论真皮下血管网皮瓣蒂部供血能力为皮瓣面积的1/4(长宽比为1:1)。

Objective To investigate the role of the pedicle in the survival of the subdermal vascu- lar network skin flap.Methods The subdermal vascular network skin flap was created on the back of the rat in the experimental group.The subdermal vascular network skin graft was made at the same position of the rat in the control group.The ratio of length to width of the flap was 4:1.The observation was carried out with naked eyes and instrument.Hair growing on the flap was one of the most important indexes of the observation.Results It was observed in 116 animals that the proximal 25 percent of the flap possessed regular colour and well-growing hair.Conclusion The pedicle of the subdermal vascular network skin flap in the rat can supply 25 percent of the whole flap.
