Abstract
Suspension of chitin and chitosan Particles (mean size of 1 μm) were found to attract Canine ncutrophild chcmotactichlly asdetermined by a checkerboard assay through polycarbonate filter with 5 μm pore size in Blind well chamber. Suspension of chitin induced chemokinetic migrations of the neutrophils. These evidences might reflect accumulation of neutrophils to chitin- and chitosan-implanted regions in dogs.
