摘要 目的探讨贫铀(depleted uranium,DU)嵌入大鼠肌肉致体内长期内污染是否会引起机体骨代谢和骨矿盐结构的损伤及其生物学特点,为DU创伤采取的早期医学处理方法和预防DU所致远期危害提供理论依据。方法采用DU片植入大鼠腓肠肌以建立DU嵌入损伤致DU长期内污染的动物模型,电感耦合等离子体质谱仪(inductive coupled plasma-mass spectrometry,ICP-MS)分析植入后不同时间点铀在骨组织中的分布和滞留规律;并在DU植入后3个月测定腰椎和股骨的骨密度、骨生物力学性能,光镜和电镜观察大鼠骨组织结构病理改变并进行形态计量学分析。结果随着植入DU剂量的不同,铀在骨骼组织中的分布浓度呈明显差异,且随着植入时间的延长,组织中的铀含量持续升高,至植入后90d达到最高峰。此后,骨骼中的铀含量开始逐渐下降,但下降速度缓慢,植入后360d骨骼中的铀含量仍维持在较高水平。DU植入后3个月,骨组织结构出现明显损伤,表现为骨小梁体积和骨小梁宽度减少、骨小梁间距增加、MAR值降低。植入DU大鼠的腰椎BMD明显降低,腰椎压缩和股骨三点弯最大载荷明显下降。结论骨骼是DU嵌入损伤后的主要蓄积器官,且滞留时间较长。DU长期内污染可引起骨量值明显降低、骨生物力学性能下降、骨组织结构出现明显损伤。应重视DU长期内污染对骨骼的损伤效应研究。 Purpose Depleted uranium(DU) is a kind of radioactive heavy metal which can enter the body by inhaling(aerosols),drinking,eating and through the wounds and then cause long time chemical and/or radioactive toxicity on critical organs.In the present study,the DU retention regulation,biological characters and mechanism of DU damage to bone after implantation were analyzed in order to clarify the potential health risks associated with chronic exposure to DU.Methods Sprague Dawley rats were surgically implanted ...
