Leukaemia is a malignant progressive disease in which the bone marrow and other blood-forming organs produce increased numbers of immature or abnormal leucocytes.
His next paper on the subject was published in 1964, when he observed a clear relationship between leucocyte antigen compatibility and antibody response to skin grafts.
By studying their granulation he could distinguish between nongranular lymphocytes, mono- and poly-nuclear leucocytes, eosinophil granulocytes, and mast cells.
The lytic process, most commonly seen in leucocytes, is caused by pore formation induced by an oligomerized octamer that organizes in a ring structure.
Platelet count test is performed by two major techniques (light scattering, electronic aperture-impedance counting) to distinguish between platelets, leucocytes and erythrocytes.
