Abstract
Background: Mobile phones have become widespread around the globe. These devices emit electromagnetic radiations (EMR) which induce oxidative stresses and reactive oxygen species (ROS) in the body tissues. Nowadays, natural antioxidants are widely used to counteract the ROS including the clove bud essential oil.
Aim: The aim of the current study is to investigate the effect of clove bud oil in protecting the parotid glands against the harmful effect of mobile phones EMR.
Methodology: Twelve adult male albino rats were randomly distributed into two groups, six as positive control group (A) exposed to the mobile phone EMR and six as experimental group (B) exposed to EMR followed by administration of clove bud oil as a treatment for 30 successive days. The parotid glands were dissected for histological examination, immunohistochemical localization of myeloperoxidase (MPO), biochemical examination for the measurement of nuclear factor kappa beta (NF-κB), and histomorphometric analysis of diameter and number of serous acini and area percentage of MPO.
Results: The histological examination of the parotid gland of group (A) revealed loss of the normal architecture of the gland, while group (B), the architecture was closer to the normal. Statistically, significant decrease in the mean values of MPO and NF-κB in group (B) as compared to group (A). Histomorphometric analysis revealed significant decrease in the diameter and number of serous acini in group (A) as compared to group (B).
Conclusions: Clove bud oil had a positive role against the ROS produced by the mobile phones EMR as it did a noticeable improvement in the structure of the parotid gland due to its antioxidant activity.
Clinical Significance: The clove bud essential oil could be introduced as a natural food preservative and as food additive due to its powerful antioxidant capacity.
