Among 24 male blood donors without anaemia who had been giving a mean of 2.2 donations per year involving a mean blood loss of about 900 ml a year, 10 (41%) were found to be depleted of storage iron. This is somewhat higher but similar to the previously recorded findings in healthy women without anaemia. The results may well support a policy of limiting blood donation to twice a year in men and...

oxamine administration. Urinary iron excretion induced with desferrioxamine (DFA) was estimated in 26 children with thalassaemia major. Four separate 24-hour urine collections were made-during a baseline period, after intramuscular injection of DFA 1 g, during blood transfusion with DFA 0 5 g/unit transfused blood, and during the post-transfusion period. Urinary iron, plasma iron, and total iro...

BACKGROUND Two new parameters low hemoglobin density (LHD) and microcytic anemia factor (Maf) have been used by Beckman-Coulter LH series analyzers as an easy screening tool for the early detection of iron deficiency. The main objective of this study was to assess if LHD and Maf could be used for assessment of iron status in blood donors and also to establish a cut-off for these two parameters ...

Haemoglobin, haematocrit, and plasma iron values were estimated on blood samples collected from 100 male and 113 female National Blood Transfusion Service blood donors, and from 83 male and 66 female age-matched control subjects. No significant differences in any of these values were found to exist between the donors and controls, and it is considered that the serum or plasma iron level is unsu...

The defective tissues causing the microcytic anemia in mk/mk mice have been studied by transplantation of marrow erythrocyte precursors into lethally irradiated recipients. Microcytic (mk/mk) marrow in irradiated normal mice produced erythrocyte parameters, blood values, spleen/body weight ratios, and reticulocyte percentages characteristic of the microcytic anemia, but splenic iron stores rema...

Studies were made on the cellular components of the blood, the serum iron concentration, and the circulating blood and plasma volumes of rats in pregnancy and on the iron transport from the maternal blood to the conception products (uterus and its contents) using radioactive iron. Anemia of pregnancy developed and was most pronounced during late pregnancy when the conception products developed ...

Anemia in patients with CKD is due to many factors. Erythropoiesis and iron homeostasis are impaired as a result of a complex chain of events, including the relative deficiency of erythropoietin, chronic inflammation, blood loss, decreased iron absorption and utilization, exogenous iron and erythropoietin acquisition via biologically unregulated mechanisms (blood transfusions and medicinal eryt...

In an effort to find practical means of distinguishing iron deficiency anemias from other types in large population groups, an investigation was made of the possibility of measuring iron in an amount of blood serum obtainable from the finger. Iron deficiency anemias are characterized by low serum iron, while other states of diminished hemoglobin formaCon show normal or even high values for seru...

research has shown that chronic, long and exhausting endurance training programs cause iron deficiency. this problem can have a negative effect on physical performance. the aim of this research was to study the effect of endurance training and iron supplement on anemic indexes [hemoglobin (hb), hematocrit (hct), red blood cell (rbc), total iron binding capacity (tcbc) and ferritin], and cytochr...
