摘要
[目的]观察某营养粉对人体免疫功能的影响。[方法]采用双盲法将103例受试者(其中男51人,女52人)随机分为对照组和营养粉组,营养粉组服用某营养粉,对照组服用与该营养粉外观相似的安慰剂,不改变生活饮食习惯,连续服用30d后,观察受试者的临床症状、体征以及免疫指标变化。[结果]与对照组相比,营养粉组受试者IgA、IgG、CD4/CD8明显增高(P<0.05);与试食前相比,营养粉组受试者IgA、IgG、CD3、CD4、CD4/CD8均明显增高(P<0.05),指标均在医学正常值参考范围内;且试食后受试者疲劳感减少(P<0.01)、精神状态变佳(P<0.01)、感冒次数减少(P<0.01)。[结论]该营养粉对人体免疫功能具有一定的增强作用。
[ Objective ] To examine the effect of a nutrition powder on human immune functions. [ Methods ] A total of 103 subjects （51 males and 52 females） were randomly divided into a control group and a nutrition powder group by double-blind method. A nutrition powder and a placebo similar to the nutrient powder in appearance were given to the corresponding groups for 30 days without changing their eating habits. The subjects＇ clinical symptoms/signs, as well as alterations in immune indicators were observed to evaluate if the nutrition powder could enhance immune functions. [ Results ] The levels of IgA, IgG, and CD4/CD8 in the nutrition powder group were obviously higher than those in the control group （P〈0.05）. The levels of IgA, IgG, CD3, CD4, and CD/CD8 in the nutrition powder group were also significantly elevated after receiving the nutrient powder （P〈0.05）, but all within the normal reference range. Moreover, in the nutrition powder group, the report of fatigue and mental state were improved （P〈0.01）, and the incidence of seasonal flu was lowered （P〈0.01）. [ Conclusion ] The nutrition oowder could enhance human immune functions.
