abstract：:The role of Na+/H+ exchange in protein kinase C-mediated effects in platelets was investigated by studying the effect of removal of extracellular Na+ ([Na+]e) on the different responses induced by phorbol 12-myristate 13-acetate (PMA) and 1,2-dioctanoylglycerol (diC8). None of the responses studied, namely, protein ph...
