Abstract
Objective To discuss the impact of vitamin A on the immune function of infants.Methods Forty healthy infants aged 2～3 years old were chosen and divided into observation group given vitamin A 1000 unit and control group given placebo for a period of 3 months.The levels of IgA,IgG,IgM,CD4,CD8,CD4/D8 in the blood of infants before and after the observation were determined.The results were statistically analyzed.Results There no significant differences were observed in the levels of IgA,IgG,IgM,CD4,CD8,CD4/D8 before the observation in the 2 groups(P0.05).But the levels of IgA,IgG,IgM,CD4,CD4/D8 in the observation group were higher than that of the control group 3 months after the observation,while the CD8 was decreased,all showing significant differences(P0.05 or 0.01).In addition,the levels of IgA,IgG,IgM,CD4,CD4/D8 in the observation group were higher than that before the observation,while the level of CD8 was reduced also showing significant differences(P0.05 or 0.01).Conclusion Vitamin A can improve the immune function of infants.
