Purification and thrombolytic effects in vivo of recombination Nattokinase on carrageenan-induced tail thrombosis in a rat model
Corresponding author:Abstract
DB104 strain and thrombolytic effects of nattokinase have been observed in vivo. The result of the enzyme purification by membrane filtration method for enzyme recovery efficiency is 82.45%. Then the enzyme was purified to Q-Sepharose ion exchange chromatography with a purification factor of 1.82 and at a yield of 66.91%. Enzyme activity was 5,457 FU/mg protein. With the carrageenan-induced tail thrombosis in a rat model, results were significantly reduced by 67.3 to 83.6% at oral doses and injected nattokinase compared with the control group at 48 h. At 72 hours the rate increased to 82-89% in the oral dose and up to 91% in the injected dose nattokinase and comparable to 90% for heparin-positive hepatitis.
