测定１１２例１～６岁亚临床维生素Ａ（ｖＡ）缺乏儿童血清ＶＡ、前白蛋白（ＰＡ）及血清铁（ＳＩ），对其中９３例分别用ＶＡ制剂、硫酸亚铁及ＶＡ加铁剂进行干预治疗一月，结果发现亚临床ＶＡ缺乏患者基础ｖＡ与ＰＡ明显相关，而单独补充铁剂后，其ＳＩ增值与ＰＡ增值无明显相关，提示ＶＡ与ＰＡ之间存在密切关系。 Serum VA, prealbumin (PA) and serum iron (SI) were measured in 112 children aged 1-6 years with subclinical vitamin A deficiency, and 93 of them were treated with VA, ferrous sulfate and VA plus iron respectively Intervention in January, the results found that subclinical VA deficiency patients with basal vA significantly correlated with PA, and iron supplementation alone, the value of SI and PA increased no significant correlation, suggesting that there is a close relationship between VA and PA.
