摘　　要：利用微血管塑料铸型扫描电镜观察这一新技术，对骨肉瘤微血管形态进行研究。按照血管三维构造及分布特点并结合组织病理特性，骨肉瘤的血管可分为三个区带：（１）外带，为密集新生的毛细血管芽。（２）中心带，血管稀疏；有大片无血区。（３）间带，即介于肿瘤边缘与中心之间的部位，血管迂曲扩张。这些血管结构特点与肿瘤的生物学特性有关。肿瘤的边缘部分是肿瘤细胞生长最活跃的部位。Abstract The microvascular structure of the osteosar-coma were investigated by Methylmethacrylatecast technique and scanning electron microscopy。Three characteristic types of capillaries werefound:The extruding club-like capillaries on thesurface of tumor seems to be newly produced;Inthe next inner zone were sinusoid and disorderlyrunning capillaries,In the central necrotic cavitywere tapering capillaries。These vascular structurewas correlated to the tumor growth and biologicalspeciality。The cells of tumor surface were most active.
