Effects of pulsed magnetic fields on neurite outgrowth from chick embryo dorsal root ganglia

Quantitation of neurite growth parameters in explant cultures using a new image processing program

“…close to zero, while an asymmetric DRG would have a high S.D. This would have been a useful measurement parameter in the study by Greenebaum et al (1996), in which a significant amount of asymmetry (measured manually) was observed in DRG's in certain treatment groups.…”

“…The relation between neurite length and NGF concentration has been reported previously (Greenebaum et al, 1996;Sisken et al, 1990) while a similar correlation has been reported for neurite area using an "interactive system" (Konings et al, 1994). In addition we found that NGF produced growth differences in the center area and neurite density although the significance is not as high as it was in the other parameters.…”

Exposure to Pulsed Magnetic Fields Enhances Motor Recovery in Cats After Spinal Cord Injury

“…23,34 Specifically designed Helmholtz coils were used, 5 and a study using an animal model to investigate the bioeffects of PMF stimulation after acute SCI was designed. The histopathology, recovery of locomotor function, and changes in somatosensory-evoked potentials (SEPs) throughout the recovery period were evaluated.…”

Influence of static magnetic fields on nerve regeneration in vitro

“…If this did occur we wanted to compare these effects with those obtained when DRG were stimulated by PEMF (Sisken et al 1984;Sisken et al 1990;Greenebaum et al 1996). The magnetic fields used in the present study were in the low to medium range, under 1000 Gauss (100 mT), in comparison to some studies using higher fields from 1 Tesla to 6 Tesla.…”

“…It appears that static magnetic fields as well as pulsed electromagnetic fields (Sisken et al 1990;Greenebaum et al 1996) may act to promote growth of neurite processes when applied with NGF to in vitro neuronal models. The data indicate that relatively high magnetic fields are required to produce a significant effect on neurite outgrowth in DRG explants.…”
