“811”是我国合成的新型络合剂,它对钍、锆有明显的促排作用。自1974年以来,我们用“811”加速人体内钚的排出,共观察了33例。结果表明:(1)给1.5克和0.6克“811”后,尿钚排出量分别为不用药时的52倍和13倍;(2)在人体试用中未发现明显的毒性。 “811” is a new type of complexing agent synthesized in our country, which has obvious promoting effect on thorium and zirconium. Since 1974, we have used “811” to accelerate the release of plutonium from our body, of which 33 cases were observed. The results showed that: (1) After 1.5g and 0.6g “811”, urinary plutonium excretion was 52 times and 13 times higher than those without medication; (2) No obvious toxicity was found in the human trial.
