This rat study assessed 30-day 2600 MHz EMF exposure effects on kidney tissue and DNA damage in blood lymphocytes, with an EMF+quercetin group included. Kidney histopathology and immunohistochemistry were reported as similar across groups, and oxidative stress markers did not significantly change. The EMF-only group showed significant DNA damage in lymphocytes by Comet assay.
Exposure of human lymphocytes to sweeping-frequency extremely low frequency magnetic field
This in vitro study exposed human umbilical cord blood lymphocytes to a sinusoidal sweeping-frequency ELF magnetic field (3–26 Hz) for 48 hours at amplitudes from 6 to 24 μT. It reports no statistically significant effects on DNA damage/repair foci or apoptosis measures overall. A non-significant trend at 8 μT showed lower γH2AX foci (p = .064) and data suggesting fewer viable cells at the same intensity, which the authors discuss as potentially protective against DNA double-strand breaks.
Effect of the radiation emitted from a cell phone on T lymphocytes in mice
This mouse study examined whether cell phone radiation affects T lymphocytes over 2–8 weeks of exposure. CD4 and CD8 subset percentages were similar across groups, but after more than six weeks, exposed groups showed increased T-cell apoptosis and reduced transformation rates compared with shams. The study also reports decreased IL-10 and increased IL-12 in exposed groups, suggesting time-dependent immunological changes under the tested conditions.
