Abstract
Erythrocyte (RBC) survival time as determined by in vivo 59Fe-labeled RBC in 6 adult sheep was 111.7 (SEM +/- 8.4) days. The plasma clearance (T/2) of 59Fe was 148 (+/- 17.3) minutes and the maximum RBC uptake of 59Fe was 52.4% (+/- 3.6%). Plasma iron turnover rate was 0.356 (+/- 0.016) mg/kg/24 hours, and RBC iron turnover rate was 0.186 (+/- 0.016) mg/kg/24 hours. Blood volume measurement was 53.5 (+/- 3.9) ml/kg of body weight.
摘要
通过对6只成年绵羊体内59Fe标记红细胞测定的红细胞（RBC）存活时间为111.7（标准误±8.4）天。59Fe的血浆清除率（T/2）为148（±17.3）分钟，59Fe在红细胞中的最大摄取率为52.4%（±3.6%）。血浆铁周转率为0.356（±0.016）毫克/千克/24小时，红细胞铁周转率为0.186（±0.016）毫克/千克/24小时。血容量测量值为53.5（±3.9）毫升/千克体重。
