微量元素锌在体内除维持多种酶活性及在应激状态时机体的代谢起重要作用外,国外有人指出近视眼与体内缺锌、铜及硒有关,与国内汪氏(1984)报导意见不一致,本文旨在研究中学生视力与血清锌关系,为近视者视力减退早期有无必要补充微量元素锌提供科学依据。实验方法以三所普通初中学生为研究对象(平均年龄为14.2岁),随机选出88名出生在同一地区,生活条件基本相似而又无明显缺锌的临床症状的男、女学生(其中正视者为27人,近视者为61人)。
In addition to maintaining a variety of trace elements in the body of zinc in vivo activity and metabolism in the stress state plays an important role, some people have pointed out that myopia and the body of zinc deficiency, copper and selenium, and the domestic Wang (1984) reported inconsistent views , This paper aims to study the relationship between visual acuity and serum zinc in middle school students, and provide the scientific basis for the supplement of trace element zinc in early stage of vision loss of myopia. Methods Three male junior and senior middle school students (mean age 14.2 years) were selected randomly from 88 male and female students who were born in the same area and had similar clinical conditions but no significant zinc deficiency 27 were myopia, myopia was 61).
