LDR能刺激成人、儿童和婴幼儿的淋巴细胞转化 ,对营养不良儿童的刺激效应较低 ,对脐血则刺激效应较明显。LDR对成人CD4 细胞的刺激效应强于CD8细胞 ,而以同样的刺激效应 ,NK细胞则需要较大剂量。对淋巴细胞NK活性也有同样规律。肿瘤病人的NK活性的刺激效应低于正常人。LDR增加了小鼠的血和脾内的T辅助 /诱导细胞的比例和肿瘤内T细胞毒性细胞。低剂量照射的淋巴细胞外液也能刺激淋巴细胞转化。预先LDR可以减轻随后大剂量照射引起的生物大分子、膜抗原和染色体的损伤。LDR可诱导鼠脾淋巴细胞产生新蛋白 ,它能增强人和动物的免疫功能。
LDR stimulates lymphocyte transformation in adults, children and infants, with less irritating effects on malnourished children and more pronounced on cord blood. LDR stimulation of adult CD4 cells stronger than CD8 cells, while the same stimulating effect, NK cells require a larger dose. NK activity of lymphocytes have the same rules. Stimulation effect of NK activity of tumor patients is lower than that of normal people. LDR increases the ratio of T helper / induced cells and the intracytoplasmic T cell cytotoxicity in the blood and spleen of mice. Low doses of irradiated extracellular fluid can also stimulate lymphocyte transformation. Pre-LDR can reduce the damage of biological macromolecules, membrane antigens and chromosomes caused by subsequent high-dose irradiation. LDR can induce spleen lymphocytes produce new proteins, it can enhance the immune function of humans and animals.
