| Abstract: | The mechanism of the release of alpha-granules constituents of thrombocytes was studied in the course of blood coagulation utilizing the fluorometric technique. The release reaction can be induced by proteolytic enzymes. The process is stimulated by the presence of extracellular Ca2+. This pattern of release reaction belongs to "release II" type. Aminazin can also induced release of alpha-granules constituents. Heparin inhibited release II induced by Ca2+ in citrated plasma, whereas streptase had no effect. |
