摘　　要：本文结合尿中核黄素排出量的测定,对BGR-AC值评价低照度作业人员核黄素状态的指导线进行了探讨。结果表明,BGR-AC值与尿核黄素排出量呈非常显著的负相关(P<0.001),并且随着核黄素摄入量的增加,BGR-AC值在Ⅰ-Ⅲ组间下降明显和Ⅲ-Ⅳ组间下降不明显。根据拟合的指数方程及雷达操纵员的核黄素需要量,我们认为低照度作业人员的BGR-AC值≤1.24为核黄素状态正常,>1.24为核黄素状态不正常。The significance of the blood glutathion reductase activity coeff i-.cient (BGR-AC) as the guide line to assess riboflavin status in 28 radar operators was studied by comparing with the amount of their urinary excreted riboflavin.The 28 subjects were randomized into 4 groups and the riboflavin intake was 0.53.mg,1.0 mg,2.0 mg,and 3.0 mg respectively.It was found that there was a significant negative correlation between BGR-AC and urinary excretion of riboflavin,and with the incrase of riboflavin intake,there was a significant decrease of BGR-AC in Groups Ⅰ,Ⅱ,and Ⅲ though the difference between Group Ⅲ and Group Ⅳ was insigificant.On the basis of the BGR-AC values of the 4 groups,an exponential equation was established which tells the riboflavin requirement of radar operators.It is defined that when BGR-AC is smaller than equal to 1.24,it is normal and when it is larger than 1.24,it means abnormal riboflavin status of the individual.
