Insights

Static magnetic field (SMF) exposure demonstrated anti-thrombotic effects in rodent models. Moderate-intensity SMF may offer a future therapeutic strategy for clot-related diseases.

Area of Science:

  • Biophysics
  • Cardiovascular Research
  • Medical Physics

Background:

  • Thrombosis, the formation of blood clots, is a significant cause of morbidity and mortality.
  • Investigating non-invasive therapeutic modalities for thrombosis is crucial.
  • Static magnetic fields (SMF) have potential biological effects that warrant exploration in thrombosis models.

Purpose of the Study:

  • To investigate the anti-thrombotic effects of static magnetic fields (SMF) in established rodent thrombosis models.
  • To evaluate the impact of different magnetic field (MF) intensities on thrombosis formation and related physiological parameters.

Main Methods:

  • Three thrombosis models were utilized: carrageenan-induced, FeCl3-induced arterial thrombosis in rats, and adrenaline-induced thrombosis in mice.
  • SMF treatments were applied at varying intensities (20-150 mT).
  • Key parameters assessed included thrombus size, mass, coagulation indices, blood pressure, and microcirculation dynamics.

Main Results:

  • SMF treatment reduced thrombus burden (tail length, mass) and improved coagulation in the carrageenan model.
  • In the FeCl3 model, SMF influenced blood pressure, plasma PAI, t-PA, thrombus mass, and protein content.
  • SMF affected microcirculation parameters (diameter, blood flow velocity) in the adrenaline-induced model.

Conclusions:

  • Static magnetic fields, particularly at moderate intensities (20-150 mT), exhibit a trend towards anti-thrombotic effects.
  • These findings suggest that SMF could be a potential future therapeutic approach for managing clot-related diseases.
