Influence of cytostatics on some platelet functions in vitro. V. Hydroxyurea

Hydroxyurea added to citrated platelet-rich plasma in vitro did not influence the aggregation of the platelets, their adhesion to glass, their release of aggregating activity, platelet factor 4 or availability of platelet factor 3. Neither did it have any effect on the uptake of 14C-serotonin, the reptilase clot retraction or the coagulation system.
