摘　　要：在兔背部两侧,随机设计相同大小的轴型皮瓣和随意皮瓣,蒂部形成“桥”后原位缝合,观察血运重建规律。发现轴型血管皮瓣血运重建较随意型皮瓣慢,在皮瓣活力的检测方法中,荧光素试验方法简单,准确。^(99m)Tc清除法可以反映皮瓣的血循环。组织透明法只能用于实验研究。This experiment was to study the blood supply of diffcrent types of skin flaps and the revascularization of the host region. The types of skin flaps used in this cxpcriment were the axial pattern flap and the random pattern flap on the back of rabbite. Forty New Zealand rabbits were divided into 5 groups at random. In gathering the data For assessment, besides the local changes such as color, swelling of the flaps, the area of survival of flaps after division of the pedicles, the tests used to observe the postoperative changes included the isotope (^(99m)Tc) clcarance test, intravenous fluorcscein test, tissue transparent method by perfusion of the flap vessels with Chcngdu ink and histologic study.The following conclusions coule be drawn: The complete revascularization of random pattcrn flap occurred at 10 days after operation and that of axial pattcrn flap was 14 days, the random pattern flaps had a quicker rate of revascularization. It was suggested that the flap ischemia was a factor which enhanced revaseularization.
