摘要
方法：以测定清晨空腹１小时尿中核黄素排出量、尿中核黄素／肌酐比值和４小时负荷尿中核黄素排出量为指标，对初入海拔３７００ｍ高原男性青年进行了为期２０天的核黄素需要量实验研究。结果：初入高原青年核黄素需要量为１．７８ｍｇ，并以此求得的供给量为２．１４ｍｇ。
Riboflavin requirement of the youth at the beginning stage of entering 3 700m high altitude was studied by determining riboflavin excretion in 1h fasting urine,the ratio of riboflavin to creatinine in urine,and riboflavin excretion in 4h urine after loading.According to the experimental result,riboflavin requirement was 1.78mg and the recommended dietary allowance (RDA) was 2.14mg.This result suggests that riboflavin intake of the youth at the beginning stage of entering high altitude should be higher than that of the residents at high altitude for long time.
