Abstract

Overview of the Study

The widespread use of mobile phones raises concerns about the possibly harmful biological impacts of the electromagnetic fields (EMF) they generate. This study primarily investigates the effects of a 2100 MHz GSM-like EMF on the auditory system of rats.

Objective

This research seeks to assess auditory impacts using histopathologic, immunohistochemical, and electrophysiological methodologies after exposing rats to GSM-like EMF.

Methods

• Subjects: Fourteen adult Wistar albino rats.
• Division: Rats split into two groups of seven — a study group and a control group.
• Exposure: The study group was exposed to a 2100MHz EMF at 5.4dBm power continuously for 30 days.

Findings

• No significant difference in Auditory Brainstem Responses (ABRs) between the groups.
• Increased signs of neuronal degeneration in the exposed group (p=0.007).
• Higher apoptotic index observed in the exposed group (p=0.002).

Conclusion

The findings support concerns that long-term exposure to GSM-like 2100MHz EMF leads to significant neuronal damage and increased apoptosis in the auditory system of rats, suggesting potential health risks associated with extensive mobile phone use.
