Abstract :
The authors have observed that the fibrinolytic process in strong magnetic fields up to 8 T was enhanced. Here they focused on the mechanism of this phenomenon. First, they observed that gradient magnetic fields eroded a fibrin gel in a specific direction. Next the authors carried out an experiment to measure concentrations of fibrin in magnetic fields up to 8 T. They measured levels of fibrin degradation products by colorimetric determination and concluded that changes in concentrations of fibrin polymers occurred in gradient magnetic fields up to 8 T. Also, by measuring transmittance at 500 nm of fibrin gels, the authors investigated the effects of magnetically formed structures of fibrin polymers on the dissolution of fibrin gels. The magnetic orientation of fibrin remained in the fibrinolytic process after coagulating in an 8 T magnetic field
