Study type: Medical/biological study (experimental study)

The influence of 1800 MHz GSM-like signals on blood chemistry and oxidative stress in non-pregnant and pregnant rabbits. med./bio.

Published in: Int J Radiat Biol 2012; 88 (5): 414-419

Aim of study (acc. to author)

To study the possible effects of radiofrequency irradiation on pregnant rabbits.

Background/further details

36 rabbits (13 months old) were studied in the following four groups: 1) non-pregnant control group, 2) non-pregnant radiofrequency-exposed group, 3.) pregnant control group and 4.) pregnant exposed group. Pregnant rabbits were exposed from the 15th-22nd day of gestation. After exposure, the rabbits were left without any intervention until the end of the 30th day gestation period. Blood samples were taken one day after delivery (remark EMF-Portal: Not clear if blood samples were taken from dams only or also from the offspring).

Main outcome of study (acc. to author)

Lipid peroxidation did not change after radiofrequency exposure, i.e. the data showed no indication for oxidative stress in the blood of pregnant rabbits upon radiofrequency exposure under these conditions. Minor changes in some blood chemistry parameters were detected. Creatine kinase-myocardial band isoenzyme and creatine kinase increases were remarkable in pregnant exposed animals (group 4).
