Numerous studies have demonstrated that the brain and blood–brain barrier, which are sensitive targets for cell phone and microwave radiation, are damaged after exposure. Additionally, ginseng has been shown to play a role in preserving the integrity of the blood–brain barrier. In this study, we investigated the immunohistochemical, genetic and biochemical effects of electromagnetic field (EMF) on the blood–brain barrier (BBB) and the protective role of ginseng on these effects. The animals were randomly allocated into seven groups (eight in each group): group I: control, group II: sham, group III: ginseng, group IV: 2100 MHz EMF, group V: 2100 MHz EMF + ginseng, group VI: 2450 MHz EMF, group VII: 2450 MHz EMF + ginseng. EMF groups exposed to EMF, 1 h day−1 for 30 days. Ginseng was administered 150 mg/kg/day for 30 days. As a result, it was determined immunohistochemically that EMF caused apoptosis in brain tissue. It was observed that cyclooxygenase-2 (COX-2) gene decreased and B-cell lymphoma/leukemia-2 gene (BCL-2)-associated X (BAX) protein increased in EMF groups, as well as apoptosis formation. On the other hand, it was concluded that ginseng decreased the harmful effects by increasing the expression of the COX-2 gene and decreasing the BAX protein in this process leading to apoptosis.
