Abstract:
:Increased chemotactic activity of peripheral polymorphonuclear (PMN) cells has been described in disease states of different etiology and may represent a common pathway in the generation of an inflammatory reaction. The suppressive effect of colchicine on PMN chemotaxis may explain its effect in apparently unrelated disorders.
