Abstract

Category: Toxicology, Physiology Tags: EMF, DNA damage, quercetin, kidney tissue, oxidative stress, rat study, comet assay URL: pubmed.ncbi.nlm.nih.gov Overview Electrical devices surrounding us are sources of electromagnetic fields (EMF). The electromagnetic radiation (EMR) from these sources induces formation of free radicals, leading to oxidative damage in various tissues. The kidney is highly sensitive to this oxidative damage. Study Aim This study evaluated the physiopathological effects of 2600 MHz EMF exposure on the kidney tissue of rats and the resulting DNA damage in blood tissue. The antioxidant quercetin (Qu) was used to attempt to reduce these effects. Methods - Male Wistar-Albino rats were split into four groups (8 rats per group): - Group 1: control - Group 2: sham - Group 3: EMF exposure - Group 4: EMF + quercetin (Qu) - After 30 days, kidney tissues were harvested for physiopathological examination. - Blood samples were analyzed for DNA damage using the Comet assay method. Findings - Histopathology of kidney tissue revealed low-level tubular dilatation damage in all groups. - Immunohistochemical evaluation gave similar results across all groups. - No significant change in malondialdehyde, catalase, and superoxide dismutase levels was found. - Significantly, the EMF group exhibited observable DNA damage in lymphocytes (P = .007, <.05). Conclusion - 2600 MHz EMF exposure did not cause severe or significant damage to kidney tissue. - However, EMF exposure notably caused DNA damage in blood tissue, highlighting a clear connection between EMF exposure and biological risk at the DNA level.
