title: [The possibility of nonenzymatic prothrombin activation during free-radical oxidation].
abstract: The existence of the prothrombin unenzymic activation by free oxygen radicals is experimentally proved. It has been found out that the 30-min-long action of free radicals generated by the ferrum-ascorbic system induced the thrombin activity. The HPLC-spectrum of this reaction mixture demonstrated four new fractions. A conclusion is made that there is an accidental system in the body responsible for the activation and degradation of bioactive substances.
