Turkije: Doorlaatbaarheid van Bloed-Hersenbarrière o.i.v. EMvelden wederom bevestigd. Bron: Electromagnetic Biolog Med 2009; 28 (2): 215 - 222 Blood-Brain Barrier Disruption by Continuous-Wave Radio Frequency Radiation. Auteurs: Sirav B, Seyhan N Aim of study (according to author) To study the effects of 900 MHz and 1800 MHz continuous wave radiofrequency exposure on the permeability of blood-brain barrier in young adult male and female rats. Background/further details: The rats were divided into four exposure groups and two control groups: 1) control males (n=8), 2) control females (n=9), 3) 900 MHz exposed males (n=8), 4) 900 MHz exposed females (n=9), 5) 1800 MHz exposed males (n=9) and 6) 1800 MHz exposed females (n=9). Endpoint effects on the neurological system: permeability of blood-brain barrier Exposure General category: mobile phone, radio frequency field, CW (continuous wave) Field characteristics Parameters 900 - 1800 MHz continuous wave (CW) exposure duration: continuous for 20 min electric field strength: 12.62 V/m Exposed system: animal (species/strain): rat/Wistar albino whole body exposure effects on the neurological system: permeability of blood-brain barrier (albumin extravasation/Evans blue detection; spectrophotometry) investigated material: supernatants of tissue homogenates (of left/right cerebrum/cerebellum) investigated organ system: brain/CNS time of investigation: after exposure Main outcome of study (according to author) The data revealed that 20 min radiofrequency exposure of 900 MHz and 1800 MHz increases significantly the permeability of blood-brain barrier of male rats. There was no change in female rats. However, female control rats exhibited a significant higher blood-brain barrier permeability (similar to those of the exposed rats) than the male control rats.
