Pulse-cytophotometric investigations on cells of inflamed tissues.

In rats the degree of mitosis of cells in the peritonitis exudate was determined after injecting a mixture of carrageenin/formalin. The same determination was performed in the skin tissue of the adjuvant-injected hind paw during adjuvant arthritis. No significant change of the mitosis rate could be found. The present data suggest a maintainance of the inflammatory reaction by immigrating cells and not by cell division.
