本研究采用Ｘ线全身照射昆明系雄性小鼠模型，观察电离辐射诱导免疫适应性反应的预照射剂量（Ｄ１剂量，７５ｍＧｙ）及其后损伤性剂量（Ｄ２剂量，１．５～２．０Ｇｙ）的时间效应。结果表明，Ｄ１与Ｄ２时间间隔６～４８ｈ，Ｄ２照后１８～２４ｈ可诱导胸腺细胞自发增殖能力及脾细胞对丝裂原（ＣｏｎＡ和ＬｐＰＳ）反应性等适应性反应。
In this study, we used X-ray whole body irradiation to observe the pre-irradiation dose (D1 dose, 75mGy) and subsequent injury dose (D2 dose, 1.5 ~ 2.0Gy) of Kunming mice induced by ionizing radiation. The time effect. The results showed that the adaptive response of thymocytes to spontaneous proliferation of thymocytes and the reactivity of spleen cells to mitogen (ConA and LpPS) was observed in 6 ~ 48h intervals of D1 and D2 and 18 ~ 24h after D2 irradiation.
