The parotid gland of rats showed numerous histopathological changes after exposure to 2100 MHz radiofrequency radiation, and increased exposure duration led to an increase in histopathological changes.

Plain English Summary

Summary written for general audiences

Thirty Wistar albino rats were divided into four groups. Groups A and B served as control groups for 10 days and 40 days with six rats each, while groups C and D were exposure groups with nine rats each. The rats were exposed to 2100 MHz radiofrequency radiation simulating a third generation mobile phone for 6 hours per day, 5 days per week, for 10 or 40 days. Exposure groups showed numerous histopathological changes in the parotid gland, with more prominent changes after 40 days compared to 10 days.

Why This Matters

The study aimed to evaluate the effect of 2100 MHz radiofrequency radiation on the parotid gland of rats in short and relatively long terms. After exposure, the rats were sacrificed and parotid glands were removed for histopathological and biochemical examinations.

Quick Questions About This Study

Rats were exposed to 2100 MHz radiofrequency radiation for 6 hours per day, 5 days per week, for 10 or 40 days.
Exposure groups showed numerous histopathological changes including acinar epithelial cells, interstitial space, ductal system, vascular system, nucleus, amount of cytoplasm and variations in cell size.
Control groups showed no histopathological changes except for two animals in the 10-day group and three animals in the 40-day group.
