Study type: Medical/biological study (experimental study)

Evaluation of hormonal change, biochemical parameters, and histopathological status of uterus in rats exposed to 50-Hz electromagnetic field med./bio.

Published in: Toxicol Ind Health 2009; 25 (3): 153-158

Aim of study (acc. to author)

To investigate the effects of 50 Hz electromagnetic fields on hormonal status and on morphology of the uterus and ovaries of rats.

Background/further details

Female rats were assigned to three exposure groups (each n=7) with one, two and three months exposure duration and a control group (n=7).

Exposure 1: 50 Hz
Exposure duration: continuous for 24 h for 1, 2 or 3 months

Main outcome of study (acc. to author)

No effects of exposure on progesterone, on 17-beta-estradiol levels, or on the morphology and weight of the uterus and ovaries were found.
Depending on exposure duration significant reductions in catalase enzyme activity were found. The most reduced catalase enzyme activities were observed in the three-months exposure group. For glutathione and malondialdehyde no significant differences between groups were found.
