采用红细胞Ｃ３ｂ受体花环试验和肿瘤红细胞花环试验，检测了硒对正常人和肿瘤病人红细胞Ｃ３ｂ受体活性及红细胞免疫粘附肿瘤细胞能力的影响。结果显示：①硒对正常人和肿瘤病人红细胞Ｃ３ｂ受体具有明显的激活作用，亚硒酸钠浓度为４×１０－４ｇ／Ｌ时，激活作用最强；②硒能明显增强正常人及肿瘤病人红细胞免疫粘附肿瘤细胞的能力，亚硒酸钠浓度为４×１０－４ｇ／Ｌ时，其增强作用最明显。
Red blood cell C3b receptor garland test and tumor red blood cell rosette test were used to examine the effects of selenium on erythrocyte C3b receptor activity and the ability of red blood cell immune adhesion to tumor cells in normal and cancer patients. The results showed that: 1Selenium had a significant activation effect on erythrocyte C3b receptors in normal and cancer patients. When the concentration of sodium selenite was 4×10-4g/L, the activation was the strongest; 2Selenium could significantly enhance normal people and tumors. The ability of the patient’s red blood cell to adhere to the tumor cells, the concentration of sodium selenite is 4×10-4g/L, its enhancement is most obvious.
