21名3～4岁健康儿童血中铁营养水平与7项免疫指标的测定,结果表明,血红蛋白<110g/L者,其血清IgG为4.32±1.40g/L;血红蛋白≥110g/L者,其IgG为6.98±1.92g/L,两组之间有显著差别(P<0.05)。且血红蛋白含量与IgG之间存在相关关系(r=0.7108,P<0.01)。血红蛋白及血清铁与其他免疫指标之间无规律性。 Twenty-one healthy children aged 3 to 4 years were tested for iron nutrition level and seven immune indexes. The results showed that the serum IgG was 4.32 ± 1.40g / L for patients with hemoglobin <110g / L, and the IgG for hemoglobin≥110g / L for IgG Was 6.98 ± 1.92g / L, there was a significant difference between the two groups (P <0.05). There was a correlation between hemoglobin content and IgG (r = 0.7108, P <0.01). Hemoglobin and serum iron and other immune indicators between the irregular.
