Abstract

Overview

The advancement of telecommunication technology and devices has made mobile phones indispensable, yet their biological effects are not fully understood. This study explores the potential histopathological changes induced by mobile phone radiation in rat parotid glands and adjacent tissues.

Materials and Methods

Thirty female Rattus Norvegicus rats were divided into three groups: 30 days exposure, 60 days exposure, and a non-exposed control group.
Each rat was exposed to two hours of mobile phone radiation daily, directed towards the same side of the face during the exposure period.
Comprehensive examinations of orofacial structures, tissue sections, and exfoliated cells were performed, with Feulgen stain used to highlight micronuclei.

Findings

Significant activation of fibroblasts was detected in the parotid gland septa of exposed groups compared to the control. Notable findings included cervical lymph node reactive changes, hyperkeratosis, and increased fibrosis in both the second exposed group and control. Vascular congestion was also heightened in the second exposed group compared to the first.

Conclusion

Exposure to mobile phone radiation may cause significant pathological changes in the parotid gland and nearby tissues of experimental rats, indicating a potential health risk.
