营养干预对雷达操纵员微量营养素代谢的影响

Effects of nutritional intervention on the micronutrients metabolism of radar operators

目的 通过营养干预 ,探讨雷达操纵员机体与暗适应有关的微量营养素代谢情况。方法 选择年龄在 1 8～ 2 9岁 ,34名雷达操纵员 (男性战士 )为实验对象 ,分对照组和实验组 ,实验组按营养素供给量标准补充VA、Zn、Se ,实验期为 4周。在实验后血清Zn、Se和VA含量较对照组增高 ,差别非常显著 (P <0 .0 1 )。结论 雷达操纵员按照营养供给量标准量连续补充 4周后 ,实验组人员血清中Zn、Se、VA含量显著增高 ,达到或超过正常营养水平 ,由此表明 ,可有效地提高机体的暗适应功能。

Objective To explore the metabolism of micronutrients related to dark adaptation of radar operators through nutritional intervention. Methods A total of 34 male radar operators aged between 18～29 years old were randomly divided into control and experimental groups. The control group were on normal diet, and the experimental group received the supplement of VA, Zn and Se in additional to normal diet. The experiment lasted 4 weeks. The levels of serum VA, Zn and Se were measured before and after the experiment. Results The levels of serum VA, Zn and Se in the experimental group were significantly higher than that in the control group after the experiment ( P <0.01). Conclusion The supplement of VA, Zn and Se for 4 weeks may elevate, the levels of serum VA, Zn and Se significantly (reached or surpassed normal levels) and suggests that VA, Zn and Se supplementation may effectively enhance the dark adaptation of radar operators.
