Comprehensive improvement and prevention of arsenic toxicity by the detoxication via acceleration of excretion from body and the detoxifying of arsenic in drinking water.

用原生产的西兰花(B)粉处理仓鼠和健康志愿者，评估砷的代谢和排泄。其次，对环境砷的脱毒过程进行了研究。B粉可促进尿中砷的甲基化和排泄。同时，对人体必需矿物质的剥夺和化学值的异常均无明显影响。在维生素B12的作用下，无机砷在还原条件下有可能转化为砷的无毒形态。我们的研究结果将有助于制定综合对策，改善症状，预防砷污染地区的新受害者。

Originally manufactured broccoli (B) powder was treated to hamster and healthy volunteer and evaluated metabolism and excretion of arsenic. Secondly, detoxifying process of environmental arsenic was investigated. B powder enhanced methylation and excretion into urine of arsenic. At the same time, there was no obvious effect on the deprivation of essential minerals and the abnormalities of chemical values. Inorganic arsenic was possible to convert to arsenobataine, innoxious arsenic form, under reductive condition with vitamin B12 action. Our results will be helpful for setting up the comprehensive countermeasures, improvement of symptoms and prevention of new victims among the arsenic contaminated area.
