用原子吸收分光光度法,检测了人发中13种元素钠、钾、钠/钾。钙、镁、钙/镁。铜、锌、铁、锰、铅、镍、锶、铬、镉的含量。 健康人头发样品采自济南市五区三县,包括工人、农民、干部、学生、及街道居民。年龄在15—60岁,均经严格体检,共计363人,作为对照组。癌患组、胃癌、肺癌经X线,内窥镜,病理学等检查确诊,按标准严格分组,共计133人。 测定结果看出:癌患组钠、钾、钙、镁、及其比值与健康组有明显差异,87％病例钠/钾低于健康组,85％的病例钙/镁高于健康组。可作为肺癌、胃癌的辅助诊断依据之一。锌、铁、锰、锶的差异也较大,故在肺癌、胃癌高发地区及高危人群发中检测以上各元素,是有一定诊断价值的。发铁随病程进展变化明显,可用于判断病人预后。铜、镍、铬、镉差异不显著。 此工作对今后肿瘤的普查及研究具有一定的意义。
By atomic absorption spectrophotometry, the human hair in the detection of 13 elements of sodium, potassium, sodium / potassium. Calcium, magnesium, calcium / magnesium. Copper, zinc, iron, manganese, lead, nickel, strontium, chromium, cadmium content. Healthy hair samples were collected from three districts in five districts of Jinan City, including workers, peasants, cadres, students and street residents. Aged 15-60 years old, have been strictly physical examination, a total of 363 people, as a control group. Cancer patients, gastric cancer, lung cancer by X-ray, endoscopy, pathology and other tests confirmed by strict standards, a total of 133 people. The results showed that the ratio of sodium, potassium, calcium and magnesium in cancer patients was significantly lower than that in healthy patients, 87% of patients had lower sodium / potassium and 85% of patients had higher calcium / magnesium than those of healthy subjects. Can be used as a diagnosis of lung cancer, gastric cancer based on one of the diagnosis. Zinc, iron, manganese, strontium differences are also larger, so in lung cancer, high incidence of gastric cancer and high risk of detection of the above elements in the hair, there is a certain diagnostic value. Hair iron changes significantly with the progress of the disease can be used to determine the prognosis of patients. Copper, nickel, chromium, cadmium difference was not significant. This work on the future of cancer screening and research has a certain significance.
