本文报导了对61例90岁以上长寿老人及70例20~69岁健康成人血清铁蛋白、血红蛋白及头发铁含量测定结果。血清铁蛋白水平随增龄而递增,而血红蛋白和头发中铁含量则随增龄而递减。贫血发生率亦随龄增加,长寿老人贫血发生率男女分别为45.2%和30%。提示老年人体内贮铁量增加,而对铁利用障碍,认为除疾病原因外可将血清铁蛋白水平随龄增加程度作为判断衰老的指标之一。
This paper reports the results of determination of serum ferritin, hemoglobin and iron content in 61 elderly people over 90 years old and 70 healthy adults aged 20 to 69 years. Serum ferritin levels increased with age, while the hemoglobin and hair iron content decreased with age. The incidence of anemia also increased with age, the incidence of anemia in elderly longevity were 45.2% and 30%. Tip elderly iron storage capacity increased, while the use of iron disorders, that in addition to the cause of the disease can increase the level of serum ferritin as one of the indicators to determine the aging.
