Abstract:

Objective  To investigate the effect of electromagnetic radiation of cellular phones on pregnant and offspring′s serum in rats. Methods  32 pregnant rats were randomly divided into the control group, the low intensity group, the middle intensity group and the high intensity group. After being exposed for 0,10,30,60 minutes, 3 times a day for 21 days, the content of immunoglobulin was determined. Results  In pregnant and neonatal rats′ serum, the content of IgG was increased in the low intensity group and the middle intensity group, however it was decreased in the high intensity group, with significant differences among the four groups (P＜0.05). The content of IgA all decreased after exposure,which was significantly different between the experimental groups and the control group (P＜0.05). Also the content of  IgM was decreased after exposure, which wassignificantly different (P＜0.05) between the high intensity group and the control group but not between the other experimental groups and the control group. Conclusion  Receiving a certain period of electromagnetic radiation from a cell phone during pregnancy could do certain harm to immune systems of both pregnant and offspring rats.
