BackgroundMost mobile phones emit electromagnetic radiation at 900 MHz or 1800 MHz. An electromagnetic field has some biological effects on the behavior of the cell population of bone. The aim of this work is to evaluate the effects of the radiation emitted by mobile phones on bone mineral density (BMD). The effects of caffeic acid phenethyl ester (CAPE) on the radiation-induced changes were also investigated.MethodsIn the study, 48 Sprague Dawley rats were used. Rats were divided into five groups as follows: control, irradiated with 900 MHz, irradiated with 900 MHz and treatment, irradiated with 1800 MHz, irradiated with 1800 MHz and treatment groups. The rats in the control group (first group) were left within the experimental setup during 30 min/day for 28 days without radiation exposure. Nine hundred-MHz radiation group was exposed to irradiate both second and third groups for 28 days (30 min/day); 1800-MHz radiation group was exposed to irradiate both fourth and fifth groups for 28 days (30 min/day). Third and fifth groups were also treated by CAPE for 28 days. Treatment groups received 10 μml/kg/day CAPE i.p. before the irradiation. Bone mineral densities were determined in all groups.ResultsBMD was found to be decreased in the irradiated groups and to be increased in the treatment groups.ConclusionsThe changes were not significant (p >0.05).
