摘要

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30 d 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。

Abstract:
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 CD4/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 powder could enhance human immune functions.
