title: Disordered development of macrophages in non-Hodgkin's lymphoma.
abstract: Macrophage development in 20 untreated patients with non-Hodgkin's lymphoma (NHL) has been studied and compared with that in 20 normal subjects. Morphometric measurements were carried out on ultrastructural features of cell, nucleus and mitochondria during 6 days suspension culture of blood monocytes in the presence of autologous serum and lymphocytes. The results were subjected to multivariate and univariate analysis of variance. Statistically significant differences were found between the subject groups with respect to the volumes and surface areas of cell, nucleus and mitochondria, to the excess surface membrane of cell and nucleus (as compared with equivalent spheres) and to the number of mitochondrial profiles per section. It would appear that the patients' cell grew less, showed less elaboration of surface features and had reduced nuclear and mitochondrial development, the latter affecting mitochondrial numbers rather than individual size. The findings provide further evidence that mononuclear phagocytes are deranged in NHL.
