White Blood Cells. White blood cells, or leukocytes, have varying function and morphology. Mononuclear leukocytes include lymphocyte B and T-ceUs, monocytes, and progenitor cells. Polynuclear granulocytes include neutrophils, basophils, and eosinophils. The most important groups in cell separation are lymphocytes, monocytes, and granulocytes. 

Density Gradient Separation. Based on specific density, each cell in a test tube finds its own position (see Fig. 1), ie, red cells at the bottom, then granulocytes, monocytes, lymphocytes, platelets, and plasma on top. Table 2 Hsts average mass density of the cellular components of blood. The actual numbers vary slightly from person to person.

The role of cytokine therapy in the management of radiation accident victims has been summarized (152). In GoiBnia in Brazil in 1987, eight radiation accident victims were treated with GM-CSF one month after radiation exposure. Marked increases in granulocyte production were induced in five persons, although this did not prevent death. 

The basic aperture impedance method can produce three-part white cell differential counts. Impedance counters can distinguish three white cell types by size the LYMPHS, mid-range cells including MONOS and BASOS, and granulocytes including NEUTS and EOS. 

Cytarabine, 4-amino-l-/3-D-arabinofuranosylpyrimidin-2(lif)-one or cytosine arabino-side (1033 R = H, X = NH2), is an established drug for the treatment of acute leukaemias of childhood and adult granulocytic leukaemia. It must be given intravenously and much of the drug becomes the corresponding inactive uracil derivative in vivo by virtue of a deaminase in the liver it interferes with DNA but not RNA synthesis, and it has incidental...

British investigators (Haddow and Timmis 1951) synthesized and studied esters of the methanesulfonic acid. The most active derivative was the dimethylsulfonic ester of 1,4-butanedione, known as busulfan. Busulfan interacts with the thiol groups of proteins and amino acids some of its metabolites can alkylate the thiols of cysteine, peptides and proteins. Busulfan exerts selective cytotoxic activity in hematopoietic bone marrow cells and inhibits the formation of granulocytes and platelets. It slightly affects the lymphoid tissue. 

Basic (pH) proteins directed against pathogens. Examples are the major basic protein from mast cells, the eosinophilic cationic proteins from eosinophils, and defensins from epithelial cells and neutrophilic granulocytes. 

In addition, the alkaloid colchicine (from Colchicum autumnale) blocks tubulin polymerization by binding to heterodimeric (3-tubulin between amino acids 239 and 254. Since it inhibits the MT-dependent migration of granulocytes into areas of inflammation and their MT-dependent release of proinflammatory agents, it is used to treat attacks of gout. Its antimitotic effect in the gastrointestinal system induces diarrhoea. Nocodazole competes for the binding site of colchicine and has similar effects on heterodimeric (3-tubulin.
