摘要
目的:观察维生素A(VA)强化食用油营养干预对少年儿童免疫功能的改善作用。方法:在四个不同地区选择VA缺乏的小学生作为研究对象,用VA含量为7500μg/kg的食用油对受试儿童进行5个月营养干预,观察血清VA水平、免疫球蛋白(IgA,IgG,IgM)和补体C3含量的变化。结果:干预组儿童的血清VA水平明显高于对照组,血清IgA和补体C3含量得到显著改善,但IgG,IgM含量与对照组未见明显差别。结论:VA强化食用油可以有效改善儿童的VA营养状况,提高其免疫功能。
Objective： To observe the effects of vitamin A （VA）-fortified edible oil on improving the immune function of children. Method- The marginally VA-deficient children were selected as volunteers in four cities of China. Nutritional intervention was conducted in the children with edible oil fortified with VA 7500 μg/kg for five months. The VA level, the contents of IgA, IgG, IgM and complement C3 in sera of the volunteers were detected at the end of intervention. Results. The levels of VA, IgA, and C3 in sera of the intervention group were significantly higher than those of the control group, but no differences of IgG and IgM were observed. Conclusions The VA status and immune function of the AD children could be effectively improved with vitamin A-fortified edible oil. [ACTA NUTRIMENTA SINICA, 2006, 28（1）： 40-42, 46]
