近几年对人发、尿及血中微量元素的研究报道较多,但对组织中微量元素含量分析报道较少。微量元素有些可以致癌、有些可以抑癌。本文对中老年人胃癌组织和非癌组织中6种微量元素含量进行了测定并对照分析。对照组标本(非癌标本)取自十二指肠球部溃疡患者切除的胃组织。实验组标本取自胃癌病人切除的胃癌组织,两组年龄均在45岁以上,均经病理切片明确诊断。采用日本岛津原子吸收光谱仪(AA-670型)测定胃癌和非癌组织中6种微量元素的含量。Cu、Zn、Fe元素用火焰原子化法测定,变异系数<5％;Ni、
In recent years, there have been many reports on trace elements in human hair, urine and blood, but there have been few reports on the analysis of trace elements in tissues. Some trace elements can cause cancer, and some can suppress cancer. In this paper, the contents of six trace elements in gastric cancer tissues and non-cancer tissues in elderly people were determined and compared. Control group specimens (non-cancer specimens) were taken from the stomach tissue removed from duodenal ulcer patients. The specimens in the experimental group were taken from gastric cancer tissues removed from patients with gastric cancer. Both groups were over the age of 45 and were diagnosed by pathological sections. The Japanese Shimadzu Atomic Absorption Spectrometer (AA-670) was used to determine the contents of six trace elements in gastric cancer and non-cancer tissues. The Cu, Zn and Fe elements were measured by flame atomization and the coefficient of variation was <5%; Ni,
