Abstract:
The effect of anisodamine(654-2),aspirin(acetylsalicylic acid, ASA),prostacy-clin (PGI2)-like substance on whole blood platelet aggregation induced by adenosine diphos-phate ( ADP ) , arachidonic acid ( AA ) and ag-gregoserpentin of Trimersurus mucrosqumatus venom (TMVA) is reported, We found that ADP,AA and TMVA caused a dose-related increase in whole blood platelet aggregation, and the impedance technique was a sensitive method to evaluate the response of platelet in physiological condition. 654-2 could promote whole bloodplatelet aggregation induced by ADP, while ASAor PGI2-like substance could obviously inhibit the whole blood platelet aggregation induced by ADF or AA, but they failed to prevent TMVA-induced aggregation, suggesting that TMVA might mediate third pathway of platelet aggregation similar to platelet activiting faetor(PAF). Furthermore, the platelet stimulated by ADP or AA was still activated by TMVA, the mechanism of which remains to be studied.
