Abstract：
:Nanocrystalline particles of chitin in the form of hydrosol in a concentration of 0.63 mg/ml have no effect on aggregation of human platelets and clotting time of platelet-poor plasma in coagulation tests. ADP-induced aggregation of human platelets was inhibited by these nanoparticles in concentrations of 0.63 and 1.00 mg/ml in comparison with the control. Intravenous administration of nanoparticles in a dose of 1 mg/kg to guinea pigs produced no anticoagulant effect. The nanocrystalline particles of chitin can be of interest as potential drug delivery systems.
