To study the effects on the body of animals after incorporation of 3H-TdR and its mechanism, the laws of distribution A retention and absorbed dose in blood , thymus, spleen, femur, heart, lung,kidney, liver, brain , spermary , small intestine and muscle were detected by liquid scintillation counter after 3H-TdR was injected into the tail vein of mouse; the process of dynamic incorporation of in the lymphocytic cell nucleus of blood , thymus , spleen and the nucleus of femur was monitored; the absorbed dose in the cell nucleus was estimated; the influence to RNA"s synthesizing and cell"s survival was observed using the technology of CLSM; A segment of Egr-1 gene was cloned with reverse transcriptase- polymerase chained reaction, the influence to the expression of Egr-1 gene in the spleen cells was observed.

为了探讨有机结合氚内污染对生物机体的影响及其作用机理，本课题应用均相液体闪烁测量技术研究了氚标记胸腺嘧啶核苷(~3H-TdR)经尾静脉注入小鼠机体后，在血液、脑、胸腺、心脏、肺脏、肝脏、脾脏、肾脏、小肠、睾丸、肌肉和股骨共12种组织器官的生物动力学分布规律及其吸收剂量；应用纸片法液体闪烁测量技术研究了~3H-TdR内污染在外周血、胸腺和脾脏淋巴细胞及骨髓细胞的动态滞留规律，估算了细胞核的吸收剂量；应用共聚焦显微镜观察了~3H-TdR内污染对脾细胞核酸合成及其存活率的作用，应用反转录PCR技术研究了~3H-TdR内污染对脾细胞早期生长反应基因-1(Egr-1)转录表达的影响。

The study on themechanisums has been a hotspot of biology and radiobiology.

值得关注的是，自从国外学者提出电离辐射旁效应概念以来，许多研究者证实旁效应的存在，对&照射细胞核才会引起细胞致命的损伤&&只有受照射细胞才受到损伤&等某些传统观念提出了有力的挑战，辐射诱导的基因不稳定性、细胞质受到照射所致的突变及旁效应等在辐射致癌中同样具有重要作用，并得到放射生物学界的确认。
