Leucocyte phagocytic response in relation to abo blood groups
Indian Journal of Physiology and Pharmacology
|July 1, 1977
Summary
Phagocytic activity of leukocytes, crucial for immunity, varied by blood group. Blood group O exhibited the highest phagocytic activity, suggesting a link between blood group substances and immune response.
Area of Science:
- Immunology
- Hematology
Background:
- Phagocytic activity of leukocytes is a key component of innate immunity.
- Individual variations in immune response may be influenced by genetic factors such as blood groups.
Purpose of the Study:
- To investigate the phagocytic activity of leukocytes in healthy individuals.
- To determine if phagocytic activity correlates with ABO blood group phenotypes.
Main Methods:
- An in vitro suspension technique was employed.
- Leukocytes from healthy volunteers were incubated with Staphylococcus aureus.
- Phagocytic activity was quantified by calculating phagocytic coefficients after Leishman staining and microscopic examination.
Main Results:
- Phagocytic activity varied among different blood groups.
- Blood group O demonstrated the highest phagocytic activity, followed by A, B, and AB.
- A potential correlation between phagocytic coefficient and ABH (O) blood group substances or their antibodies was observed.
Conclusions:
- Blood group phenotype may influence leukocyte phagocytic activity.
- Further research is warranted to elucidate the relationship between ABH (O) blood group antigens/antibodies and phagocytosis.

02:45Blood Transfusion and Agglutination
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

01:21Structure and Function of Leukocytes
An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.

01:12The ABO Blood Group
The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.

01:19Rh Blood Group
The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
01:10Blood Typing
Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
