Effect of weak and ultraweak combined magnetic fields and low-intensity microwaves on regeneration in the planarian Dugesia tigrina

Abstract

Regeneration (blastema growth) in Dugesia tigrina was accelerated if prior to transection the planarians were exposed to a weak constant magnetic field (42 μT) combined with an ultraweak alternating magnetic field (40 nT, 3.7 Hz); lesser stimulation was obtained with weak microwaves (100 μW/cm2 at 36 GHz). Field exposure after transection produced only half of the effect (magnetic field) or none at all (microwaves).
