Effect of electromagnetic radiation of cell phone on brain tissue of pregnant and fetal rats

Objective To investigate the effect of electrom agnetic radiation of cellular phone on of bra intissue of pregnant and fetalrats.Methods Pregnantrats were radiated with various levels of electromagnetic radiation and then the contents of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and malondia ldehyde(MDA)inpregnant and fetalrats bra in tissue were tested.Results No significant difference was found in pregnantrat bra intissue among the four groups.In rats bra intissue,the content of SOD(U/mg·prot)decreased a fterirradiation with significant differences among the high intensity group(38.56±4.62),middle in tensity group(40.05±4.74)and control group(43.53±5.38,P<0.05).The content of GSH-Px(U/mg·prot)decreased after irradiation,and the differences were significant among the three groups(33.80±6.29,35.03±7.18,40.58±8.03,respectively,P<0.05).The content of MDA(nmol/mg·prot)increased after irradiation,and the differences were also significant among the three groups(4.09±0.68,3.95±0.64,2.89±0.57,respectively,P<0.05).There was no significant difference between low intensity group and control group in the content of SOD(42.79±5.06),GSH-Px(39.95±9.02)and MDA(3.05±0.76,P>0.05).Conclusion Receiving certaininten sity of electrom agnetic radiation from cell phone during pregnancy has certa in harm effect on an tioxidant system of offsprings bra intissue in rats.
