[New erythrocyte indices characterizing body function in relation to iron in regular blood donors].
Sixty six females and 124 males were studied that were regular blood donors at the first, second, third, fifth, tenth, 20 th, 30 th, 40 th, 50 th blood donation, transversally. The level of hemoglobin, hematocrit, erythrocyte number were subjected to light fluctuations during the follow-up period, being essentially reduced towards the end of the study. Most dynamic changes were observed in erythrocyte iron, significantly growing after the second-third blood donation in males and after the fifth - in females, whereafter it was reduced under the initial level, that reduction persisting till the end of the follow-up period among the males. The percentage of saturation of hemoglobin with iron was respectively changed as well as the level of erythrocyte iron in litre blood, in litre erythrocytes, the absolute iron content in erythrocyte, and the index characterizing erythropoiesis activity (ICEA).
