摘　　要：目的: 观察复合营养素对人体认知功能的改善作用。方法: 男性青年46名,随机分为2组,实验组口服复合营养素胶囊,对照组口服安慰剂,持续60 d。参照《长-鞍团体智力测验手册》进行智力测验,用韦式记忆量表测验短时记忆能力;用仪器测定闪光融合频率和视觉复杂反应时,并用4 h负荷实验测定受试者的维生素营养状况。结果: 实验组经复合营养素补充后维生素营养状况得到改善,智力测验的4项成绩明显高于实验前,3项高于对照组;受试者测验视觉复杂反应时的成绩表明,实验组 3项测试指标的反应时间明显缩短,2项指标的错误次数明显减少;而对照组前后的测验结果未见明显改变。结论: 补充复合营养素有利于改善人体的学习、记忆和理解等认知能力。Objective: To observe the effects of nutrients-compound supplementation (NS) on cognitive function. Method: Forty six young male volunteers were randomly divided into 2 groups, NS and control (CT). NS group was supplemented with nutrients-compound while CT group received placebo for 60 d.The cognitive function of all volunteers were examined by 《CHANG-AN Handbook of Group Intelligence Test》 and Wechsler Memory Scale(WMS). Their vitamin status was assessed by 4-h load test at the end of experiment. Results : The vitamin nutriture of NS group was significantly better than that of CT. Many achievements of cognitive test of NS group were obviously increased compared to that before supplementation or that of CT. The visual responding time was shortened in 3 tests and the error number was decreased in 1 test of NS group, while no significant change was observed in CT group. Conclusion: Supplementation with the nutrients-compound is beneficial to improvement of cognitive function such as learning, memory and understanding.
