雷达作业部队人体锌,硒状态调查研究

本文对雷达操纵员与非操纵员人体锌、硒状态进行了调查研究。实验结果提示,两组血浆锌、硒含量有显著差别,而头发锌、硒则无明显差别。表明血浆锌、硒反映人体近期营养状况。调查期间正值飞行训练旺季,雷达操纵员低照度作业时间长,机体维生素A、锌、硒代谢增加,暗适应时间延长。故低照度作业部队在注意其维生素A状态外,还应注意锌、硒的补充,才能维持良好的暗适应功能。

An Investigation of Zinc and Selenium Status on the Dark Adaptation of Radar Operators

This investigation shows the difference of Zu and Se status between the radar operators and non-operators. The results reveal that plasma Zn and Se contents of radar operators are significantly lower than those of the non-operators, but no statistical significance in hair.It is very likely that the plasma Zn and Se reflect recent status, because during training period the radar operators work more than 4h / day in the low illumination chamber. It suggests that the RDA of Zn and Se of radar operators should be increased in order to improve dark adaptation.
