锌是人体内许多金属酶类的组成部分,或酶的激活剂,也是保证小儿生长发育必不可少的微量元素。而头发中含锌量的测定,是诊断小儿锌缺乏症和指导治疗及判定疗效的可靠依据。我院门诊于1987—07～1987—10,凡疑似小儿锌缺乏症者,均取其头发0.5～1.0g,采用My—x403型原子吸收分光光度计测定发锌含量,共500例进行分析。其中男297例,女203例,年龄8mo～14岁,1岁以内的27例占54％,1～3岁的1 Zinc is a component of many metal enzymes in the body, or enzyme activator, but also to ensure the growth and development of children essential trace elements. The determination of the amount of zinc in the hair is a reliable basis for the diagnosis of zinc deficiency in children and guide the treatment and determination of efficacy. Our hospital in 1987-07 ~ 1987-10, who suspected zinc deficiency in children, are taking the hair 0.5 ~ 1.0g, using My-x403 atomic absorption spectrophotometer determination of hair zinc content, a total of 500 cases were analyzed. Among them, 297 males and 203 females were aged from 8 to 14 years old, with 27 cases accounting for 54% within 1 year of age and 1 to 3 years old
