[AGGREGATION OF METABOLICALLY DEPLETED HUMAN ERYTHROCYTES]
Blood storage for 14 days at 4°C alters erythrocyte aggregation, leading to echinocyte formation and reduced rouleaux. Fresh plasma cannot reverse these changes in stored red blood cells.
Area of Science:
- Hematology
- Biophysics
Context:
- Blood storage is crucial for transfusion medicine.
- Understanding erythrocyte changes during storage is vital for maintaining blood product efficacy.
Purpose:
- To investigate the aggregation behavior of erythrocytes in autologous plasma after prolonged cold storage.
- To identify morphological and biochemical changes in erythrocytes during 14 days of storage at 4°C.
Summary:
- Photometry and light microscopy revealed decreased ATP content, formation of echinocytes and spheroechinocytes, and a reduction in the rouleaux form of erythrocyte aggregation after 14 days of blood storage.
- Stored blood exhibited aggregates of echinocytes.
- Addition of fresh plasma did not restore normal erythrocyte shape or aggregation in stored blood.
Impact:
- This study elucidates the complex changes in erythrocyte aggregation during blood storage.
- Findings contribute to understanding the mechanisms behind red blood cell degradation and aggregation, potentially informing strategies to improve blood preservation techniques.

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.
On the other...
Structure and Function of Erythrocytes
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...
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.
EPO then...
