作者测定了胃癌男性患者及正常人的血硒水平与血锰、铜和锌水平的关系。胃癌患者的全血硒浓度及其标准差为19.3±0.8微克/100毫升;在血浆中则为11.8±0.5微克/100毫升。而对照组分别为全血22.0±0.8微克/100毫升,血浆为14.1±0.3微克/100毫升。胃癌患者的血硒水平明显地低于正常对照组。在恶变及转移癌病人也可以看到这种情况。血硒浓度与红细胞压积之间有正相关,而血硒水平与血红蛋白之间无任何的相互
The authors tested the selenium levels in blood of patients with gastric cancer and normal blood levels of manganese, copper and zinc. Whole blood selenium concentrations in patients with gastric cancer and their standard deviation were 19.3 ± 0.8 μg / 100 ml; in plasma they were 11.8 ± 0.5 μg / 100 ml. While the control group were 22.0 ± 0.8 μg / 100 ml whole blood and 14.1 ± 0.3 μg / 100 ml plasma respectively. Selenium in patients with gastric cancer was significantly lower than the normal control group. In malignant and metastatic cancer patients can see this situation. There is a positive correlation between blood selenium concentration and hematocrit, but no correlation between blood selenium level and hemoglobin
