摘    要:应用电镜x射线显微分析仪电子探针x射线微量分析,测试人体肝细胞癌中不同部位微量元素含量。结果表明:肝癌细胞内Cu含量差异显著高于正常;Al和Zn则低于正常;癌旁肝细胞核内Cu含量差异显著高于癌中心细胞核及胞浆。提示:癌旁肝细胞内Cu的沉积,在肝细胞癌的癌变中可能起阻抗作用。

关 键 词:电子探针微量分析  肝肿瘤    癌旁组织 ̄*,微量元素

Abstract:sing electron microscope equipped with an X-ray microanalysis, the heptocellular carci-noma(HCC)specimens(4 cases from surgical operation)and their controls(3 cases from acci-dent)were studied.The specimens were routinely post-fixed in 1%OsO4,but the sectionwere not stained with uranyl acetate and lead citrate. The contents of trace elements-copper,zinc,iron and aluminum were tested in the cancerous center, cancerous side portion and nor-mal liver The results showed that:the content of copper in HCC was higher than that in nor-mal liver(P<0.01);the accumulation of copper in the nuclei of cancerous side portion weremuch more in excess than that in the nuclei of cancerous center;the content of cancerous sideportion were zinc were decreased in HCC,Our data suggest that the accumulation of copperin the cancerous side portion may be the effects hindering the development of HCC. Excesscopper in the nuclei may be closely related to biological macromolecule,particularly the met-alenzymes and DNA in nuclei.
