TAUSTA:  Tiedetään että pitkäaikainen altistus matalataajuiselle elektromagneettiselle säteilylle (LLER) ,jota kännykästä tulee, voi aiheuttaa haittoja

BACKGROUND:
Long term exposure to low level electromagnetic radiation (LLER) by using cellular phones causes serious health problems.

Koejärjestelyssä käytettiin Wistar rottia.  ja ne altistettiin 45 minuutin LLER:lle  900 MHz etäisyydeltä, joka vastasi kännykän käyttäjien  etäisyyttä altistukseen.  Siten otettiin verinäyte ja katsottiin  serotoniinit ja  glutamiinihapot. Veren serotoniinit olivat   kaiketi nousseet merkitsevästi  mutta glutamiinihapoissa ei ollut muutosta. Jos  5-HT pitoisuudet siten nousevat altistuksesta, se  voinee johtaa  viivästyneeseen  oppimiskykyyn spatiaalisen muistin vajeeseen.

METHODS:  Ten male Wistar Albino rats were anesthetized 30 min before the LLER exposure, 0.5 ml blood was taken from the tail vein of rats in order to determine control values. Rats were grouped by three and placed on a plexi-glass flat. A fixed equivalent frequency emitter device was used. A sign to be an electromagnetic field 15.14 V/m (608 mW/m2) in strength in the head region with 100 kHz FM modulation at 900 MHz was applied to the animals. After calculating the ideal position for the device, electromagnetic LLER energy was applied for 45 minutes from a distance to be equal with energy transmitted by a mobile phone from a 0.5-1 cm distance to their head regions. After 1.5 hours and before the rats awoke, 0.5 ml of blood was taken from the tail veins in order to determine the treatment values.

RESULTS:

Plasma 5-HT and glutamate levels were measured by enzyme immunoassay (EIA) using commercial kits. It was found that a single 45 min of LLER exposure increased the blood 5-HT level significantly, but did not change the glutamate level of rats.

                                                                                                                                                                                                                                                                           

CONCLUSION: It was concluded that even a single 45 min of LLER exposure may produce an increase in 5-HT level without changing the blood glutamate level. Increased 5-HT level may lead to a retarded learning and a deficit in spatial memory (Tab. 2, Fig. 2, Ref. 24).
