The changes in membrane structure of rabbit polymorphonuclear (PMN) leukocytes during bacterial phagocytosis was investigated with scanning electron microscope (SEM), thin-section, and freeze-fracture techniques. SEM observations of bacterial attachment sites showed the involvement of limited areas of PMN membrane surface (0.01-0.25mum(2)). Frequently,(More)
It is well known that polymorphonuclear (PMN) leukocytes move and that lysosomes move within these cells (21). It has been suggested that micro-tubules or microfilaments are involved in these movements (1, 17, 22). This paper demonstrates that microfilaments are associated with lysosomes and suggests that organized contractile microfila-ments are involved(More)
Six different statistical methods for comparing limiting dilution assays were evaluated, using both real data and a power analysis of simulated data. Simulated data consisted of a series of 12 dilutions for two treatment groups with 24 cultures per dilution and 1,000 independent replications of each experiment. Data within each replication were generated by(More)
