Abstract
Current study aimed at determining the consequence of Radiofrequency (≈1800 MHz) electromagnetic radiation (RF-EMR) on the histological, hematological and histochemical properties of selected tissues of rat and to assess morphological changes associated with such exposures. Three groups of thirty rats of which two groups of twenty rats were subjected to average radiation of ≈1.40 W/cm2 at 24 m from the base of two different telecommunications network mast for 5 weeks. Histochemical, hematological and histological analyses of the rats were afterward carried out on selected tissues of the experimental animals using standard procedures. Impacts of radiation were noted in the exposed groups of rats. There was rise in white blood cells with variations in other blood parameters; the sperm motility and sperm count of the exposed rats is lower than the control; the liver of the exposed rats shows pronounced dilated sinusoids, distorted architecture, hyperchromatic nuclei, congested central vein, with change of hepatocytes structure; the heart shows gross distortion of cardiac muscular architecture with distorted irregular cardiac muscle fibres and wider interfibres spaces; kidney showing hyperchromatic nuclei, gradual loss and degeneration of flattened squamous epithelial cells lining and testis shows grossly distorted seminiferous tubules and epididymis with loss of cellular structure and an area of inflammatory changes with complete absence of spermatozoa, which may lead to low fertility. This study shows that radiofrequency electromagnetic radiation may induce morphological changes in various tissues of living systems in rat.
