Different effects between group I and group II antagonists on TXB2 formation (TXA2metabolites). Platelets were preincubated with various concentrations of antagonists and then stimulated with 0.03 U/mL thrombin. TXB2 was measured by RIA Kit. Values are given as the mean ± SD (n = 3). Open and solid symbols represent group I and group II antagonists, respectively.
