Abstract
Female OF1 mice were chronically exposed to a sinusoidal magnetic field of 50 Hz and 15 µT to determine the possible histological alterations in their adrenal glands caused by this exposure. Mice were sacrificed at 14 weeks of age, and adrenal glands were studied by light and electron microscopy. Both glands of a total of 30 female control mice and 30 experimental ones were used for this study. The morphological parameters measured did not show significant differences between the compared groups. In 30% of the exposed mice one or several of the following morphological variations were found: enlarged capsule, with infiltration of both the zonae glomerulosa and fasciculata; wider zona glomerulosa with hyperplasic micronodules, with the cells showing swollen mitochondria with dilated cristae; in the zona fasciculata, several groups of fuscinophilic cells, dysplasia, hyperplasia with hypertrophy, and even adenoma in a small percentage; in the zona reticularis, the cells had increased lipid content and mitocho...
