摘要
目的：进行久居高原战士核黄素需要量实验研究，旨在为制定高原部队核黄素供给量标准提供参考依据。方法：在海拨３７００ｍ高原居住１～４年的５０名战士随机分５组，每人每日核黄素摄入量分别为０．６５、１．１５、１．６５、２．１５、３．１５ｍｇ，于实验第２０天测定１ｈ空腹尿中核黄素排出量、尿中核黄素／肌酐比值和４ｈ负荷尿中核黄素排出量，用两回归交点法求出久居高原战士核黄素需要量。结果：久居高原战士核黄素需要量为１．５６ｍｇ，并以此求得的供给量为１．８７ｍｇ。结论：久居高原战士核黄素需要量高于平原人群，因此，增加高原战士核黄素摄入量对维持机体正常生理功能和提高机体对高原的适应能力可能是有益的。
Objective: To determine the riboflavin requirement of the long staying soldiers at high altitude to provide a reference data for recommended dietary allowance (RDA) for the soldiers. Methods: Fifty soldiers living at 3700 m altitude for 1～4 years were randomized into 5 groups. Riboflavin at doses of 0.65 mg, 1.15 mg, 1.65 mg, 2.15 mg and 3.15 mg per capita per day was given to the soldiers in the 5 groups respectively. The riboflavin excretion of 1h fasting urine, the ratio of riboflavin to creatinine in urine and the riboflavin excretion in 4h load urine were determined on the 20th day. The riboflavin requirement was calculated using intersection point of two lines of regression equation. Results: The riboflavin requirement was 1.56 mg and RDA was 1.87 mg for the soldiers living at high altitude. Conclusion: Long staying soldiers need larger riboflavin requirement than people at the plain, which suggests that it is necessary to increase riboflavin intake for the long staying soldiers at the high altitude in order to keep their normal physiological function and improve their fitting capacity to the high altitude.
