Cellular dry mass during macrophage development in malignant lymphoma.
In order to throw light on known mononuclear phagocyte disturbances in malignant lymphoma, scanning and integrating microinterferometry was employed to measure dry mass in developing mononuclear phagocytes after 0, 2, 4 and 6 days of suspension culture, using cells from 19 healthy subjects, 19 patients with Hodgkin's disease and 17 with non-Hodgkin's lymphoma. Analysis of variance showed that highly significant increases in dry mass (approximately twofold) occurred over the six-day period. No significant differences were found between the subject groups, nor were any attributable to age or sex. In terms of their dry mass, mononuclear phagocytes from lymphoma patients undergo developmental changes in suspension culture that are similar to normal, but a comparison with earlier cell volume studies suggests that differences in cellular water content may be present.
