“…Because permeability change of BBB has been a matter of concern as it could result in health hazard on brain, many research groups attempted to confirm their results. However, a few studies (Aubineau and Tore 2005;Schirmacher 2000) found the low level RF-EMF affect BBB permeability in vivo and in vitro, whereas others (Tsurita et al 2000;Kuribayashi et al 2005;Franke et al 2005;Finnie et al 2006) failed to replicate Salford's findings.…”

“…These exposure levels range from a low level comparable to the study by Salford to a moderate level of 2.4 times the safety guideline. Several studies which evaluated changes in BBB permeability after RF-EMF exposure found that the exposure under lower SAR levels than the 2.0 W/kg did not modify the BBB permeability (Tsurita et al 2000;Kuribayashi et al 2005;Franke et al 2005;Finnie et al 2006). Our present results not only support their findings, but also provide new information for considering the effects of RF-EMF exposure on the microcirculation.…”

“…Although many investigators have reported the effects of RF-EMF on BBB permeability, these studies mainly used histological evaluation (Salford et al 1994;Tsurita et al 2000;Finnie et al 2006;Fritze et al 1997). On the contrary, we examined not only BBB permeability but also other microcirculatory parameters in vivo.…”

Authors review the importance of studying the effects of electromagnetic fields (EMF) on microcirculatory system, especially in respect of possibility that vasculature may have direct and indirect role in interaction of static magnetic fields (SMF). We outline the physiological importance of microcirculation and relatively new methods of evaluation technique in vivo and explain in details the local and/or whole body exposure effects of SMF with range of 0.3-180 mT, power frequency EMF with range of 0.1-30 mT and microwaves at 1.5 GHz with range 0.08-8 W/kg brain average specific absorption rate (SAR) on microcirculatory systems in different tissues in experimental animals.

“…One of the most remarkable findings in recent years was the change in permeability of blood-brain barrier (BBB) related to RF-EMF exposure (Salford et al 1994). Most of these studies, however, have been performed by the histological investigations due to postmortem examination (Salford et al 1994;Tsurita et al 2000;Finnie et al 2006;Fritze et al 1997). On the other hand, little information is available about the effects of RF-EMF exposure on cerebral microcirculation.…”

“…Because neuronal damage to the cortex, hippocampus, cerebellum, and basal ganglia due to RF exposure has been reported earlier [1], many research groups have investigated whether the RF-EMF from mobile phones can affect the brain in various ways by focusing on biochemical and morphological alterations: cerebral blood flow [2][3][4][5], blood-brain barrier permeability [6,7], neurotransmitter balance [8,9], and nerve cell damage [1,10]. In these studies, the possible effects of RF exposure on the nervous system remain controversial.…”

The increasing use of mobile phones has raised public concern about the possible biological effects of radiofrequency electromagnetic field (RF-EMF) exposure on the human brain. To investigate the potential effect of RF-EMF exposure on the brain, we examined the behaviors and hippocampal morphology of C57BL/6 mice after sub-chronic exposure to RF-EMFs with a relatively high SAR level (5.0 W/kg). We applied a 2-hour daily exposure of WCDMA 1,950 MHz using a reverberation chamber that was designed for whole-body exposure for 60 days. In the behavioral tests, RF-EMF did not alter the physical activity or long-term memory of mice. Moreover, no alteration was found in the neuronal and glial cells in the hippocampus by RF-EMFs. In this study, we showed that sub-chronic whole body RF exposure did not produce memory impairment and hippocampal morphological alteration in C57BL/6 mice.Key Words: Hippocampus, Memory, Mobile Phone, Radiofrequency Electromagnetic Field, Sub-chronic Exposure.
