  • Title: Plasmodium berghei: the influence of blood volume changes on the malaria-induced anemia in Balb/C mice.
    Author: McGuire RW, Haines HB.
    Journal: Z Parasitenkd; 1985; 71(3):305-12. PubMed ID: 3892956.
    Abstract:
    Malaria-induced anemia exceeds that attributable to direct parasite destruction of erythrocytes. Since spleen and liver weights increase significantly, hemodilution may account for part of this excessive anemia. To determine the role of hemodilution in the etiology of anemia, vascular volumes were measured with Evans blue and isotope dilution techniques. The Evans blue dilution technique showed that blood volume increased 20%, in infected Balb/C mice. However, when blood volume was measured with Evans blue bound to protein prior to injection or with iodinated albumin and chromium-labelled red blood cells no significant change was detected. Evidently the permeability of the vasculature and/or erythrocytes of infected mice was increased so that injected Evans blue occupied a space larger than the vascular volume before becoming bound to plasma proteins. We conclude that hemodilution is not involved in the excessive anemia of Plasmodium berghei-infected Balb/C mice.
