酸性非特异性酯酶标记T淋巴细胞是目前检测T细胞较好的方法,其特点是结果稳定,重复性好;方法简单;标本可以长期保存.辐照对机体的免疫功能的损伤与辐照剂量成正比.本文就整体照射和离体照射条件下以及不同剂量照射对外周血T淋巴细胞的改变作了测定,肯定了照射剂量对T细胞的影响,提出在辐照损伤和修复过程的研究及防治药物研究中使用该法的可能性. Acid non-specific esterase-labeled T lymphocytes is a better method for detecting T cells, which is characterized by stable results, good repeatability, simple method and long-term preservation of the samples. The damage to the immune function and the dose of radiation Is proportional to the overall irradiation and ex vivo irradiation and different doses of irradiation on peripheral blood T lymphocytes were measured to determine the impact of irradiation dose on T cells in the irradiation damage and repair process and The possibility of using this law in the prevention and treatment of drug research.
