✦ Synopsis
The effect of wettability of 14 polypeptide derivatives upon adhesion and activation of platelets was investigated with reference to release reactions from adhered platelets, using radioisotope labeling and radioimmunoassay method. The serotonin release was more significant from platelets adhered to polymer materials to which a large number of platelets are adhered. However, no clear relationship was found between a d h e s i o n of platelets a n d p-thromboglobulin release from adhered platelets. Therefore, stimuli inducing serotonin release and p-thromboglobulin release were considered to be from different origins. The trend in p-thromboglobulin release was well correlated with the extent of morphological change of adhered platelets as observed by scanning electron microscope. It was suggested that the determination of released p -thromboglobulin in association with the measurement of platelet adhesion could be useful for evaluation of blood compatibility of materials.
