小儿缺铁性贫血血清锌铜铁含量测定研究

ZINC, COPPER AND IRON CONTENTS OF BLOOD SERUM IN 47 CHILDREN WITH ANAEMIA FROM DEFICIENCY OF IRON

本文报道用原子吸收光谱仪测定缺铁性贫血小儿的血清锌、血清铜及血清铁的均值较正常组明显降低(P<0.01),差异显著。贫血组之血清锌和铁、锌和铜及铁和铜呈正相关,3者呈一致性降低,即小儿同时缺乏几种微量元素,提示微量元素之间有相互作用。贫血伴低锌、低铜以1岁内(牛乳喂养为主)及6～7岁(偏食)占多数,分别为31.90％、40.40％。所以缺铁性贫血的小儿应同时检测血清锌和血清铜,以得早期诊断和治疗。

The zinc, copper and iron contents of blood serum were measured by atomic absorption spectrometer. Their average contents in 47 children with anaemia from deficiency of iron were obvioiously less than those in the control, the difference between the contents of the two groups was very obvious (P<0.01). The consistent decrease of zinc, copper and iron contents showed that there were correlative effects on hemapoiesis between the such microelements. Among the 47 cases of anaemia with less zinc and less copper, 31.9% occured in the babies less than one year old (mainly fed on cows milk) and 40.4% in the students at the age of 6-7 years (with special food hobby or food boycott), but there was no obvious difference in sex (P>0.05). Zinc and copper contents of blood serum must be measured in the children with anaemia from deficiency of iron in order to be diagnosed and cured as early as possible. An active propaganda of the scientific knowledge of feeding children must be carried out. The meals for babies must be directed. The animal foods, especially the protein from animal, must be suitably supplemented.
