目的：为保证初入高原部队战士缺氧适应对维生素C（Vc）进行维生素需要量研究，为初人高原部队战士Vc供给量标准提供依据。方法：选择空运进人西藏高原（3700m）的青年男性新兵50名，分为5组，每组10人。第1～5组每人每日Vc摄取量为20、40、60、80、110mg，实验期为14d。在实验膳食中Vc摄取进行了严格控制。以空腹血浆Vc含量，24h尿总Vc排出量，口服500mgVc4h尿中总Vc排出量等3项评价指标。结采：实验期第14天测定以上3项指标第4组以上达到标准要求。结论：初人高原部队战士Vc需要量为80mg，供给量为96mg，高于平原地区，但与久居高原战士需要量相同。
Objective: To ensure the entry of plateau army fighters hypoxia adaptation of vitamin C (Vc) vitamin requirements for the early plateau units soldier Vc supply standards provide the basis. Methods: Fifty young male recruits who were airlifted into Tibet Plateau (3700m) were divided into five groups of 10. Groups 1 to 5 per day Vc intake of 20,40,60,80,110 mg, the experimental period of 14d. Vc intake in the experimental diet was strictly controlled. Three fasting plasma Vc levels, 24-hour urinary total Vc excretion and 500mg Vc4h oral total Vc excretion were evaluated. Results: The 14th day of the experiment period to determine the above three indicators in the fourth group to meet the standard requirements. CONCLUSION: The initial VCR requirement of VCR is 80mg and the supply is 96mg, which is higher than that of the plain area, but it is the same as that of the soldiers living in the plateau for a long time.
