Chronic Exposure to Extremely Low Frequency Electromagnetic Field Induces Mild Renal Damages in Rats med./bio.

Published in: International Journal of Zoological Research 2011; 7 (6): 393-400

Aim of study (acc. to author)

To investigate the effect of long-term exposure to extremely low frequency magnetic fields on kidney function and morphology in rats.

Background/further details

45 male rats were divided in three equal groups: exposed group, sham-exposed group and control group.



Exposure Parameters
Exposure 1: 50 Hz
Exposure duration: continuous for 24 h/day for 135 days

Main outcome of study (acc. to author)

The plasma concentration of creatinine and urea nitrogen was statistically significant increased in the exposed group compared to the sham exposed and control group. This result was accompanied by a marked vascular congestion in the renal cortex and a reduction in red blood cell count in glomerular capillaries. However, there were no changes in total protein, albumin and globulin levels.
