RESUMO
Objective To explore the metabolism of micronutri ents related to dark adaptation of radar operators through nutritional intervent ion. Methods A total of 34 male radar operators aged between 18 ～29 years old were randomly divided into control and experimental groups. The c ontrol group were on normal diet, and the experimental group received the supple ment of VA, Zn and Se in additional to normal diet. The experiment lasted 4 week s. The levels of serum VA, Zn and Se were measured before and after the experime nt. Results The levels of serum VA, Zn and Se in the experime ntal group were significantly higher than that in the control group after the experiment (P<0.01). Conclusion The supplement of VA, Zn an d 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 su pplementation may effectively enhance the dark adaptation of radar operators.
