摘　　要：目的　对一种材料防护贫铀 (depleteduranium ,DU)粉尘的效果进行生物学评价。方法　吸入DU粉尘后第1、3天 ,收集无防护组和有防护组大鼠的血、肺、气管、肾和肝 ,测定铀含量 ,计算防护效果。结果　有防护组各组织 (体液 )铀浓度均明显低于无防护组 ,防护效果在 71 2 %～ 96 1%之间。结论　该种防护材料可阻挡绝大部分DU粉尘进入呼吸道 。Objective To evaluate the biological effect of a kind of protective cover against inhalation of depleted uranium (DU) dust particles. Methods At 1 and 3 d after inhalation of DU dust particles, uranium concentrations in the blood, lung, bronchia, kidney, and liver of the rats in the protected group and non protected group were measured and the efficiency of protection was calculated. Results Uranium levels in all tissues and fluids of the rats in the protected group decreased significantly to 71.2%-96.1% as compared with those in non protected group. Conclusion The protective cover is effective to reduce the harm due to inhalation of DU dust particles.
