0 the oxygen-carrying substance in red blood cells -- hemoglobin
abnormally low levels of haemoglobin in the blood.
Here, macrophages incorporate iron, which is then released from haemoglobin and passed to transferrin.
Two other participants had low haemoglobin levels with normal mean corpuscular volumes.
Variation in hookworm infections was the strongest explanatory variable for haemoglobin, erythrocyte protoporphyrine and serum ferritin levels.
Therefore, diseases that arise from abnormal haemoglobins (haemoglobinopathies) are systemic and have pleiotropic manifestations.
In those not taking iron a progressive drop in the haemoglobin was observed, the lowest level being reached at 32 weeks gestation.
Assays of parasite proteinase activity by other workers indicate that acid-soluble peptides or amino acids are released, by the digestion of haemoglobin.
No significant associations occurred between haemoglobin values and worm egg counts (separate analyses for each worm).
A small amount of blood was used to determine haemoglobin concentrations.
