Abstract

Antifibrinolytic effect of lumbrokinase in mice, in vivo, was studied. Liquid phase lumbrokinse from Lumbricus rubellus was purified by column chromatography method. Lumbrokinase was orally inserted to mice. Although oral dosage of lumbrokinase, to investigate whether lumbrokinase in mice causes antifibrinolytic effect, we have concentration of lumbrokinase varied, and detection of antifibrinolytic effect was carried out using a FDP (fibrin degradation product) test and euglobulin fibrinolytic activity test. FDP test and euglobulin fibrinolytic activity test were compared the data of PBS ingestion. control with lumbrokinase ingestion. As a result, FDP was increased in 7.8mg, 26mg lumbrokinase concentrations after 25 hours succeeding oral prescription of lumbrokinase, and decreased after 49 hours, but 7.8mg lumbrokinase ingestion more increased than 26mg. Also, FDP of PBS ingestion control and 1.3mg lumbrokinase ingestion were not been observed nothing. Euglobulin fibrinolytic activity of PBS ingestion control and 1.3mg lumbrokinase ingestion were not been observed any clear zone after 8, 25, 48 hours, and 7.8mg and 26mg were observed the most largest clear zone after 25 hours and decreased after 48 hours. However, antifibrinolytic effect of oral prescription of lumbrokinase in mice was observed. Now we need to determine an efficient amount of lumbrokinase for antifibrinolytic effect.
