Summary
1. Destruction of platelets by glass and fixation of platelets by Amberlite IR 100
was studied.
2. A clear difference was established between platelets in whole blood, without anticoagulant
and platelets in native plasma. Almost no platelets were destroyed or retained when
in native plasma.
3. Male platelets in native plasma were clearly more resistant than female platelets
in native plasma.
4. Differences were observed at different periods of the menstrual cycle.
5. Native male plasmas, very rich in platelets did not change in number after contact
with glass or after passage through Amberlite IR 100. Thus calcium influenced neither
destruction, nor fixation of platelets by resin.
