Histopathology of the Harderian gland of rodents exposed to ELF magnetic fields
Abstract The Harderian gland is a possible magnetosensitive organ. The aim of this study was to look at the possible effects on the Harderian gland of mice after exposure to an artificial magnetic field. Sixty 0F1 three-month old female mice were selected for this study. The mice were exposed continuously to an artificial magnetic field of 1 G (10 −4 T) and 50 Hz during a three-month period. The effects were evaluated histologically. The results show, only in the experimental group, non-reversible histopathological lesions with anaplasic foci in 26% of Harderian glands. These lesions also include in situ development of adenocarcinomas. Confidence intervals applied to the statistical studies…
Inhibition of Melatonin in the Plasma of Third-Generation Male Mice under the Action of ELF Magnetic Fields
The pineal gland has been considered a magnetic receptor organ that regulates circadian rhythms by means of the secretion of melatonin, a potent oncostatic agent that prevents the initiation and promotion of cancer. ELF electromagnetic radiation, similar to that generated by power lines, can alter melatonin plasma levels.To study this effect, 4 OF1 mice generations have been reared subjected to a lifelong 15 μT, 50 Hz magnetic field action. This magnetic field was generated inside a Helmholtz coil system. The concentration of melatonin in the blood has been determined on 40 male mice of the third generation by means of RIA, as they reached sexual maturity (3 months).A radical decrease, more…
