Mobile phones are high performance devices that consume a lot of energy and also generate heat due to microwaves transmitted by the handset . This heat is mainly created by the high frequency electromagnetic fields that transmit voice or data in mobile communications. Moreover, mobile phone radiatiion can also cause non-thermal biological effects which have been shown to induce oxidative stress and cell damage. The components of mobile phones also become hot during operation, due to the heating of the battery, processor, screen and radiofrequency broadcasting compnonents.
The skin is the largest organ system of the body. The integrity of a healthy skin plays a crucial role in maintaining physiological homeostasis of the human body and its protection against numerous exogenous traumata . Connective tissue is one of the many basic types of animal tissue and is found between other tissues in the body. Especially dermal connective tissue connects all distinct cells and tissues of the skin to a functional organ . Fibroblasts constitute the principal component of the connective tissue.
Regeneration of complex structures such as the skin after injury requires dramatic changes in cellular behaviour. Regenerating tissues initiate a program that includes diverse processes such as wound healing, cell death and dedifferentiation. Moreover, newly regenerated tissues must integrate into preexisting cellular structures .
We used a bioassay which permits the evaluation of the effect of oxidative stress resulting from the radiation of an actively transmitting mobile phone by evaluating the regeneration process of connective tissue fibroblasts. The experimental setup was adapted to a realistic situation which has been shown to be more meaningful than a controlled situation at laboratory conditions using “test” generators with invariant parameters such as intensity, frequency etc..
In addition, we also studied the question whether the Qi-Shield device might be able to protect the cell regeneration process from oxidative stress due to mobile phone radiation. According to the manufacturer, Waveguard GmbH, D-02625 Bautzen, Germany, “human beings and the environment are always in direct frequency exchange. Every body needs natural waves to stay in balance. It is the unnatural frequencies, on the other hand, that disturb this harmony … We have also developed Qi technology, which protects against electrosmog with natural frequencies”.
