Anomalous erythrocytes produced by rabbits with liver damage
Abstract:
Rabbit "stress macroreticulocytes" complete their membrane sialic acid content after a short "homing" in the liver. Since also normal rabbit reticulocytes are characterized by a low membrane sialic acid, the role of the liver in the maturation of these cells was investigated. For this purpose red cell modifications consequent to a severe liver steatosis, induced in rabbits by a diet lacking choline, were investigated. Animals with liver damage showed severe anemia and red cell membranes were demonstrated to have a low sialic acid content. Moreover rabbits with severe fatty liver, unlike normal animals, were not able to restore the viability of desialylated normal young erythrocytes. On the basis of these and others evidences we suggest that rabbit liver plays an important role in physiological maturation of reticulocytes.

Lifecycle of Erythrocytes
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups.
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
