The microcirculatory architecture of colonic neoplasms was prepared with methylmethacrylate cast. Scanning electron microscopy showed that microcirculation was deficient in the central area of neoplasms, but increased markedly and become claw, sinus and sphere patterns in appearance at the periphery of neoplasms. The microcirculation of the transitional mucosa lost its typical hexagon structure, becoming larger in diameter and showing increase of branches. These results suggest that the technique described in this article can be used to show the morphologic changes of neoplastic microcirculation, which may be worthy for the future investigation of neoplasm development.
采用甲基丙烯酸甲酯铸型法制备结肠肿瘤的微循环结构。扫描电子显微镜显示，肿瘤中心区域微循环不足，但在肿瘤周边明显增加，并呈现出爪状、窦状和球状外观。过渡黏膜的微循环失去了典型的六边形结构，直径变大且分支增多。这些结果表明，本文所述技术可用于显示肿瘤微循环的形态学变化，这可能值得未来对肿瘤发展进行研究。
