Disorders of Erythrocytes
A hyperimmunoglobulin E syndrome with normal chemotaxis in vitro and defective leukotaxis in vivo
Abstract:
A 26-yr-old male with a lifelong history of atopic dermatitis and recurrent severe staphylococcal abscesses was found to have hyperimmunoglobulinemia E. Evaluation of both the humoral and cellular aspects of chemotaxis in vitro showed both neutrophils and monocytes to be normal. However, quantitative neutrophil migration in vivo was significantly suppressed using the patient's own serum as the attractant. This defective migration in vivo was partially corrected by serum from normal donors as the attractant and also partially corrected following plasma infusion in this patient. Evaluation of quantitative leukocyte migration in vivo may be most useful in patients suspected of defects of leukocyte mobility.

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.

Blood Transfusion and Agglutination
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...
