目的 :研究低照度作业人员营养干预对血浆蛋白、血浆游离氨基酸含量及夜视功能影响。方法 :驻渝某雷达团战士 34人 ,年龄 1 8～ 2 9岁 ,分为实验组和对照组 ,实验组人员每天加服一定剂量牛磺酸及多种微量营养素。实验期限为 4周 ,分别在服药前、服药 2周及服药 4周检测受试人员快速暗适应时间。结果 :低照度作业人群 ,服用牛磺酸和多种复合微量营养素制剂 2周后 ,快速暗适应功能即大幅度提高 ,服用 4周后效果更佳。营养干预后 ,实验组 PAB、CER、TRF三种血浆蛋白均有所升高 ,而蛋氨酸 ( Met)、异亮氨酸 ( Iie)和亮氨酸 ( Leu)等必需氨基酸含量则降低。结论 :适当补充牛磺酸及 VA、B族维生素、VC、微量元素 Zn、Se能有效提高低照度作业人群暗适应功能
Objective: To study the effect of nutrition intervention on plasma protein, plasma free amino acid content and night vision function of low-intensity workers. Methods: A group of soldiers stationed in Chongqing 34 soldiers, aged 18 ~ 29 years old, divided into experimental group and control group, the experimental group plus a daily dose of taurine and a variety of micronutrients. The experimental period was 4 weeks, before taking the drug, taking the drug for 2 weeks and taking the drug for 4 weeks, the subjects were tested for fast dark adaptation time. Results: After 2 weeks of taking taurine and a variety of complex micronutrients, the fast dark adaptation function increased significantly in low-illumination workers, and the effect was better after 4 weeks. After nutritional intervention, the plasma levels of PAB, CER and TRF in the experimental group increased, while the contents of essential amino acids such as methionine, isoleucine and leu decreased. Conclusion: Adequate supplementation of taurine, VA, B vitamins, VC and trace elements Zn and Se can effectively improve the dark adaptation function in low-illumination workers
