Proaggregatory and inhibitory effects of 2-O-ethyl analogues of platelet-activating factor (PAF) on human and rabbit platelets.

abstract：:The relationship between platelet aging and early markers of membrane activation have not been defined clearly. Activation markers expressed during prolonged storage are similar if not identical to those that appear after exposure to thrombin. Using flow cytometry, we investigated platelet membrane expression of CD62P...
