Incorporation of (75)selenomethionine ((75)SeM) has been used to study platelet production in rabbits. Radioactivity of platelets was low after the intravenous administration of (75)SeM and rose to a maximum approximately 3 days ... 4-5 days. In vivo reutilization of (75)SeM previously incorporated into plasma proteins was not detected. In vitro incorporation of (75)SeM by platelets in platelet-rich plasma was not ... Acute hemorrhage 24 hr before administration of (75)SeM increased the incorporation of (75)SeM into platelets. ...
