Spezifische Wirkung einiger tierischer und bakterieller Polysaccharide auf Leucocytenin vitro

Summary Different purified polysaccharides, mucopolysaccharides, phosphatides and carbohydrat-sulfonic acids have been investigated for their effect on stimulation of leucocytic migrationin vitro. The bacterial polysaccharides of proteus,S. marcescens, shiga and shiga fullantigen, have been found to be of high specific activity. All other compounds have much less or no activity. Therefore it might be concluded that the type of bacterial polysaccharides which promote leucocytic migration belong to a highly specific group.
