作者利用灵敏、准确、简便、价廉的金电极微分阳极溶出伏安法检测140例乳腺癌和消化道恶性与良性肿瘤患者头发与血清中的硒含量,以99位健康人的相应数据作为比较对象。结果发现:胃癌(29例)、食道癌(16例)和肠癌(24例)患者头发的硒含量平均值分别为463、385和423ng/gm。50位健康人的相应数据为740ng/gm与癌患者有显著差异(P<0.001)。胃癌(32例)和乳腺癌(9例)血清硒平均含
The authors used sensitive, accurate, simple, and inexpensive gold electrode differential anodic stripping voltammetry to detect the selenium content in hair and serum of 140 patients with malignant and benign breast cancers and digestive tract cancers, and compared the corresponding data of 99 healthy people. Object. The results showed that the mean values of selenium in hair of patients with gastric cancer (29 cases), esophageal cancer (16 cases) and colorectal cancer (24 cases) were 463, 385 and 423 ng/gm, respectively. The corresponding data for 50 healthy individuals was 740 ng/gm, which was significantly different from cancer patients (P<0.001). Incidence of serum selenium in gastric cancer (32 cases) and breast cancer (9 cases)
