Role of reactive nitrogen species in blood platelet functions.

abstract：:A platelet substitute, Synthocytes, is being developed for the prevention and treatment of thrombocytopenia. Synthocytes are composed of fibrinogen adsorbed on heat stabilised albumin microcapsules of defined size. The purpose of this study was to perform experiments in vitro to investigate the capacity of Synthocytes...
