Abstract:
Dietary survey, physical examination and blood tests were carried out on kindergarten children from two to seven-year old in Wuhan, excluding some influencing factors such as malnutrition and so on. Three groups, 50 children each, were differentiated according to serum vitamin A level .avita-minotic (011 mmol/L). Immunological parameters were determinated before and after vitamin A supplementation. The results showed.'there were significant differences of S-IgA,C3 and lymphocyte transformation active response to PHA and lysozyme between vitamin A deficiency and normal group, but not on IgG, IgA, IgM and PHA skin test. After vitamin A supplementation these immunological functions could be improved. So we concluded vitamin A in subclinic deficiency could influence immune function too, but it could be recovered through vitamin A supplementation.
