Cep telefonlarından yayılan 900 MHz elektromanyetik alanların kırık iyileşmesine etkisi: Sıçanlarda deneysel çalışma

Öz

Amaç: Çalışmamızın amacı 900 MHz frekansındaki cep telefonlarından yayılan elektromanyetik alan (EMA)’ların kırık iyileşmesi üzerine etkisi olup olmadığını araştırmaktı. Çalışma planı: Çalışmaya ortalama ağırlıkları 256 g olan iki eşit gruba ayrılan 30 erişkin erkek Wistar albino sıçan alındı. Tüm sıçanların sağ tibialarına parmakla bastırılarak transvers kırık oluşturuldu ve kırıklar intramedüller K-teli ile tespit edildi. Grup 1, sekiz hafta boyunca haftada 5 gün, günde 30 dakika 900 MHz frekansında EMA’ya maruz bırakıldı. Grup 2 (kontrol grubu) ise EMA uygulanmaksızın aynı deney şartları altında tutuldu. Sıçan tibialarında kırık kaynamasıyla ilgili radyolojik, mekanik ve histolojik inceleme yapıldı. Bulgular: Çalışma ve kontrol grubunun radyolojik, histolojik ve manuel biyomekanik skorları arasında anlamlı derecede farklılık vardı (sırasıyla p=0.020, p=0.006 ve p=0.032). Çalışma grubundaki skorların tamamı kontrol grubundakilere göre daha düşüktü. Çıkarımlar: Bu çalışmanın sonuçları cep telefonlarından yayılan 900 MHz frekansındaki EMA’nın sıçan tibia kırık modelinde kırık iyileşmesini anlamlı derecede olumsuz yönde etkilediğini göstermektedir.

Effect of 900 MHz electromagnetic fields emitted from cellular phones on fracture healing: an experimental study on rats

Abstract

Objective: The aim of this study was to investigate the effect of electromagnetic fields (EMFs) at 900 MHz frequencies on bone fracture healing.
Methods: The study included 30 adult male Wistar albino rats (average weight: 256 g) divided into two equal groups. Transverse fracture was created manually by pressing a finger on the right tibias of all rats and fractures were fixed intramedullary using a K-wire. Rats in Group 1 were exposed to EMF at 900 MHz frequency 30 minutes a day, 5 days a week for 8 weeks. Group 2, the control group, was kept under the same experimental conditions without EMF exposure. Radiological, mechanical and histological examination of tibial fracture healing was performed.
Results: There was a significant difference between radiological, histological and manual biomechanical scores of the study and control groups (p=0.020, p=0.006 and p=0.032, respectively). All scores were lower in the study group than the control group.
Conclusion: Results of this study demonstrate that EMF at 900 MHz of frequency emitted from cellular phones has a significantly negative effect on bone fracture healing in a rat tibia model.
