【摘要】 研究了预先给予双嘧达莫（ＤＰ）和腺苷－磷酸（ＡＭＰ）对不同剂量 Ｘ射线照射小鼠免疫功能的影响。采用 ＢＡＬＢ／Ｃ纯系小鼠给予一次性不同剂量（０、 １、 ２、 ４Ｇｙ）Ｘ射线照射。照射前给予ＤＰ２ｍｇ和ＡＭＰ５ｍｇ，检测胸腺细胞自发增殖反应能力和脾细胞对ＣｏｎＡ的增殖反应能力的变化。结果表明：单纯给予 ＤＰ十ＡＭＰ组胸腺自发增值反应能力和脾细胞对 ＣｏｎＡ的增殖反应能力较对照组明显下降，但 １Ｇｙ和 ２Ｇｙ Ｘ射线照射前预先给予 ＤＰ和 ＡＭＰ能显著增强小鼠胸腺自发增殖反应能力和脾淋巴细胞对ＣｏｎＡ诱导的增殖反应能力。更多还原

【Abstract】 The effects of DP and AMP on the immune function in X-ray irradiated mice with different doses were studied in this dissertation.Mice(BALB/C) were irradiated with different doses(0,1,2,4Gy) of X-rays.The spontanous proliferation of thymocytes and ConA-induced proliferation reaction of splenocytes in mice pretreated with DP(2mg) and AMP(5mg) were detected. The results were as follows:the spontanous proliferation of the thymocytes and the ConA-induced proliferation reaction of splenocytes in mice injected with DP and AMP decreased markdely, but increased significantly in mice treated with DP and AMP prior to irradiation by 1Gy and 2Gy X-rays.更多还原
