Mast cells were counted in 122 patients with psoriasis and 80 healthy volunteers, at different times after scratch from 30 min up to 14 days. Koebner's phenomenon was induced in 74% of patients with active disease (63/85) and in 37.5% with stationary psoriasis (6/16). Mast cells were enumerated also

Heat-denatured DNA from HeLa cells interacts with natural aa well as synthetic polysaccharides. Polysaccharides with a molecular weight of 10 000 or greater are required before the interaction takes place. Glucose does not inhibit the interaction nor will it produce it.
Both wild-type and attenuated strains of poliovirus type 3 were found to replicate in the U-937 cells, an established cell line derived from human histiocytic lymphoma. However, preincubation of the cells with phorbol ester (PMA) that brought about the typical adherent macrophagelike appearance of t
## Abstract A study, designed to define the optimal conditions for infecting L, HeLa and human diploid cells with Mengo RNA, showed that the three cell types differ with respect to (a) the concentration of sucrose (in PBS) that produces maximum stimulation of infectious center (I.C.) formation (0.6
