Effect of exposure to extremely low electro-magnetic field during prenatal period on mice spleen. med./biol. By: Bayat PD, Ghanbari A, Saeid B, Khazaei M, Ghorbani R, Ayubian M
Published in: Indian J Exp Biol 2011; 49 (8): 634 - 638 ( full article, PubMed Entry , Journal web site )
Aim of study (according to author)
To study the effects of extremely low frequency magnetic fields on the embryogenesis of mice, particularly on the development of the spleen.
48 pregnant mice were divided into six groups (each group n=8): 1) control group, 2) sham exposed group, 3) - 6) exposure groups starting with exposure on different days of gestation (1-5, 6-10, 11-15, 16-20).
General category: magnetic field, low frequency field, 50/60 Hz (AC)
| 50 Hz |
exposure duration: continuous for 10 h/day on 5 days
|magnetic flux density: 6 mT |
FIELD View further expo parameters
animal (species/strain): mouse/NMRI
whole body exposure
Methodsinvestigated material: tissue slices (in vitro), newborns
investigated organ system: immune system
time of investigation: after exposure
Main outcome of study (according to author)
Total body weight of newborns, the volume of spleen, and the number of megakaryocytes decreased following the exposure to extremely low frequency electromagnetic fields. The complete period of gestation was sensitive to exposure and the initial days were more sensitive, i.e. the effects were more pronounced.
