We studied the production of granulocyte-macrophage colony-stimulating factor (GM-CSF) by peripheral blood mononuclear cells from 48 patients with aplastic anemia by using an enzyme-linked immunosorbent assay. Detectable concentrations of spontaneous GM-CSF production, ranging from 1.0 to 480 pg/ml (mean +/- SD, 51 +/- 100 pg/ml), were observed in 45 of 48 patients. These concentrations were not significantly different from those observed in normal controls. Phytohemagglutinin-stimulated production of GM-CSF in patients with aplastic anemia, ranged from 1.0 to 2,610 pg/ml (mean +/- SD, 754 +/- 550 pg/ml), which was significantly higher than in normal controls (p < 0.01). The spontaneous production of GM-CSF increased following antilymphocyte globulin (ALG) treatment in 7 of the 11 ALG responders and in 4 of the 14 nonresponders (p = 0.08). The present observations support the hypothesis that ALG functions as an inducer of hematopoietic growth factor in order to restore hematopoiesis.

D007963	Leukocytes, Mononuclear	Mature LYMPHOCYTES and MONOCYTES transported by the blood to the body's extravascular space. They are morphologically distinguishable from mature granulocytic leukocytes by their large, non-lobed nuclei and lack of coarse, heavily stained cytoplasmic granules.

D010835	Phytohemagglutinins	Mucoproteins isolated from the kidney bean (Phaseolus vulgaris); some of them are mitogenic to lymphocytes, others agglutinate all or certain types of erythrocytes or lymphocytes. They are used mainly in the study of immune mechanisms and in cell culture.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
