Objective: 

Most of the studies on biological effects of mobile phone exposure are focused on brain. However, nobody knows whether mobile phone exposure affects other internal organs during the talking. Therefore, the aim of this study was to investigate the effects of 900 MHz radiofrequency radiation exposure on oxidative stress level of some internal organs of rats, which primarily have their heads exposed.

Methods: 

The study was carried out on 21 Wistar Albino adult male rats. The rat heads in a carousel exposed to 900 MHz radiofrequency radiation emitted from a generator, which simulate mobile phones. For the study group (n: 14), rats were exposed to the radiation for 2 h per day for 10 months. For the sham group (n: 7), the same procedure was applied to rats except that the generator was turned off. At the end of the study some of the oxidative stress parameters such as catalase, myeloperoxidase, malondialdehyde (MDA), total oxidant status (TOS), total antioxidant capacity (TAC) and oxidative stress index (OSI) were measured in lung, kidney and heart of rats.

Results: 

The results showed that the parameters such as TOS and OSI increased in the lung of radiation-exposed rats (p<0.05). However, parameters such as catalase, miyeloperoxidase, TOS and TAC were also increased in the kidney of exposed rats (p<0.05). On the other hand, only OSI increased in the heart of exposed rats (p<0.05).

Conclusions: 

Some of the oxidative stress parameters in the lung, kidney and heart of the rats, which primarily had their brains exposed, can be altered by 900 MHz mobile phone exposure.
