Published in: Bioelectromagnetics 2003; 24 (2): 139-147

Aim of study (acc. to author)

To investigate the effects of static magnetic field exposure on pharmacologically induced hypertension in rabbits.

Background/further details

Hypertensive and vasoconstrictive actions were induced by L-NAME (a nonselective NOS inhibitor) or norepinephrine.

Main outcome of study (acc. to author)

Without treatment of pharmacological agents, no statistically significant differences in the hemodynamics and blood pressure changes were observed between sham and static magnetic field (SMF) exposure.
Under pharmacologically induced hypertensive conditions, SMF exposure leads to significantly attenuated vasoconstriction and suppressed elevation of blood pressure.
No statistically significant changes in the vasoactive substances were found.
