摘　　要：目的探讨β-胡萝卜素对反复呼吸道感染(RRI)患儿体液和细胞免疫功能的影响。方法采用免疫比浊法及间接荧光法测定60例反复呼吸道感染患儿服用β-胡萝卜素3个月前后血清免疫球蛋白及T细胞亚群变化,观察疗效及其对免疫功能的影响。结果治疗后患儿血清免疫球蛋白、CD3、CD4、CD4／CD8均高于治疗前,差异有显著意义(P<0．05,0．01)。RRI患儿呼吸道感染次数减少。总有效率达93．5％。结论β-胡萝卜素能增强RRI患儿体液和细胞免疫功能。Objective To investigate the effects of β - carotene on immune function of children with recurrent respiratory trace infection. Methods Serttm immunoglobulin and T lymphocyte subset were determined by immunoturbidimetry and indirect fluorescence in 60 children with recurrent respiratory tract infection before and after β - carotene orally administrated three months, its effects were observed on clinic effect and immune function. Results Serttm immunoglobulin and CD3, CD4, CD4/CD8 in children with recurrent respiratory tract infection who administered orally β - carotene were higher than those before treatment in three months, there were significant difference （P 〈 0.05, 0.01）. Recurrent rate of the disease decreaseed, and recent effective rate was 93.5%. Conclusion β - carotene can increase humoral immunity and cell immunity function in children with recurrent respiratory tract infection.
