摘要
取成人胃和大肠管状腺癌(Ⅱ级)23例,在透射电镜下进行观察,结果表明胃和大肠腺癌的细胞核超微结构基本相同,细胞游离面微绒毛和胞质分泌颗粒等则有许多不同之处,文中对这些异同表现进行了讨论,认为根据它们各自超微结构特点,可以做为追踪转移癌的依据。
23 cases of adult tubular adenocarcinoma (grade II) of stomach and large intestine were observed with TEM.The results indicatedthat the ultrastructure of riuclei were roughly the same between tubular ade-nocarcinoma cells of stomach and large intestine,but there were many di-fferenccs in free surface of cells and plasmatic secretory granules.The di-ffereuces and similarity discussed above provided bases of ultrapa thological Set at the root of the tumour
