[Effectiveness of terrilytin in the treatment of experimental pulmonary vascular thrombosis]

The thrombolytic effect of Aspergillus terricola proteinase terrilytin was studied in 24-hour experimental pulmonary vascular thrombosis of rabbits. The drug was dissolved in polyvinylpyrrolidon and injected into the blood flow in doses of 175 and 220 PU/kg by two routes: locally (into the thrombosed vessel) and systemically. The drug produced a high thrombolytic effect irrespective of the administration and dosage; however, the effect was more marked in local infusion of terrilytin in a dose of 220 PU/kg. No side effects were observed.
