摘　　要：1989年1月至6月分别在北京友谊医院儿科、天坛医院儿科选择新入院1～6岁肺炎病儿65例和在门诊选择28例健康儿童,静脉取血测定其血中维生素A、锌、铜、钙的含量和血清白蛋白及T细胞亚群。实验结果表明,肺炎病儿血清维生素A(36.9±23.2μg/dl)、锌(106.6±31.9μg/dl)的含量明显低于健康儿童(血清维生素A 55.5±18.7μg/dl;锌133.7±30.1μg/dl),有统计学上的差异(P<0.01)。血清铜、铜/锌比值肺炎病儿明显高于健康儿童,两组儿童也有统计学上的差异(P<0.01)。肺炎病儿血中总T细胞和T_R百分数及T_R/T_S比值明显低于健康儿童,两组儿童总T细胞和T_R百分数及T_R/T_S比值均有显著性差异(P<0.05)。血清钙和血清白蛋白含量两组儿童均无显著性差异。本研究结果表明,血清维生A、锌含量肺炎组儿童明显低于健康组儿童,而血清铜含量和铜/锌比值则相反,几种T细胞亚群也有不同。若改善儿童的维生素A和锌的营养状况,可能会减少儿童呼吸道感染性疾病发生的机会。Sixty -five pneumonia and twenty-eight healthy children were selected for experimental and control groups from You Yi and Tian Tan hospital of Beijing.Their age was one to six years.Serum Vitamin A, zinc concentrations in pneumonia group(36.9±23.2μg/dl and 106.6±31.9μg/dl)were lower than that of control group(55.5±18.7μg/dl and 133.7 +30.1ug/dl), there was significant difference (P<0.01) .Serum copper and Cu/Zn in pneumonia group were significantly higher than that of control group(P<0.01) .Serum total T cell, TR% and TR/TS in pneumonia children were sighificantly lower than that of healthy children ( P<0.05 ) .No difference of serum calcium, albumin was found between two groups.The results showed that improvement of Vitamin A nutritional status may decrease the incidence of pneumonia in children.
