Ginkgo biloba prevented mobile phone-induced oxidative stress and cellular injury in rat brain tissue.

Plain English Summary

Summary written for general audiences

Researchers investigated the effect of Ginkgo biloba on mobile phone-induced oxidative damage in rat brain tissue. Mobile phone exposure increased malondialdehyde, nitric oxide, xanthine oxidase, and adenosine deaminase while decreasing superoxide dismutase and glutathione peroxidase activities in brain tissue. Ginkgo biloba treatment prevented these oxidative alterations and the mobile phone-induced cellular injury in brain tissue.

Why This Matters

Rats were exposed to 900 MHz electromagnetic radiation from a mobile phone for seven days at one hour per day. In the treatment groups, rats were exposed to EMR and pretreated with Ginkgo biloba. Control groups were kept under the same conditions with the mobile phone turned off. The researchers suggested reactive oxygen species may play a role in the proposed mechanism for mobile phone biological side effects.

Study Details

we investigated the effect of Ginkgo biloba (Gb) on MP-induced oxidative damage in brain tissue of rats.

Rats (EMR+) were exposed to 900 MHz EMR from MP for 7 days (1 h/day). In the EMR+Gb groups, rats wer...

Oxidative damage was evident by the: (i) increase in malondialdehyde (MDA) and nitric oxide (NO) lev...

Reactive oxygen species may play a role in the mechanism that has been proposed to explain the biological side effects of MP, and Gb prevents the MP-induced oxidative stress to preserve antioxidant enzymes activity in brain tissue.
