RAPD Profiling, DNA Fragmentation, and Histomorphometric Examination in Brains of Wistar Rats Exposed to Indoor 2.5 Ghz Wi-Fi Devices Radiation

Figure 5

Paraffin sections stained by haematoxylin and eosin (H&E) ×400 for histomorphometry examination of brain (cerebrum) tissues of rats as follows. (a) Photomicrograph of control group shows normal architecture (H); section of the brain is composed of nerve cells (NC) and glia cells (arrow) and blood vessel (arrow head) disposed within the brain parenchyma. Section is free from collections and inflammatory cells infiltrations. (b) Photomicrograph of group 2 (30-day RF exposure) shows section of the brain with vascular congestion (L); the parenchyma is free from collection. (c) Photomicrograph of group 3 (45-day RF exposure) shows sections-nerve cells (NC) and neuroglia (arrow) appear as in control. (d) Photomicrograph of group 4 (chronic exposure) shows section of the brain with vascular congestion (L); the parenchyma is free from collection.
