本研究目的在于弄清雷达工作人员在日常劳动条件下硫胺素代谢的变化,为制订其需要量提供科学依据。 研究对象为珠江三角洲地区某雷达站工作员32人,均男性,年龄16～34岁,等分为四组,每组8人。实验分二期:第一期为饱和期4天,每人每日补给硫胺素10mg,第四天补给15mg,饱和试验(口服5mg硫胺素,收集负荷4小时尿)证明尿中硫胺素排出量均已从实验前的缺乏水平提高到正
The purpose of this study is to clarify the changes of thiamine metabolism under routine working conditions and to provide a scientific basis for formulating its requirements. The research object is a radar station in the Pearl River Delta region 32 staff, both men, aged 16 to 34 years old, is divided into four groups, each of eight people. The experiment is divided into two phases: the first phase of the saturation period of 4 days, daily supply of thiamine 10mg, the fourth day of supply 15mg, saturation test (oral 5mg thiamine, collecting the load of 4 hours urine) prove that urinary thiamine Superoxide dismutase have increased from the lack of pre-experiment levels to positive
