Assessment of adaptive response of gamma radiation in the operating room personnel exposed to anesthetic gases by measuring the expression of Ku 80, Ligase1 and P53 genes
Introduction: Staffs of operating room are continuously exposed to anesthetic gases and ionizing radiation. Adaptive response, as a defense mechanism, will occur when cells become exposed to a low dose of factors harming DNA that causes in the next exposures to higher doses o...
متن کاملSynergic Effect of TC99-m Gamma Radiation and Non-ionizing Radiation of Wi-Fi on Count, Morphology and Motility of Sperms in Rats: An Experimental Study
Background: Given the effects of ionizing radiation on biological tissues and their irreversible tissue damage, this project aimed to determine the synergic effect of TC99-m gamma radiation and non-ionizing radiation of Wi-Fi on sperm characteristics in rats. Materials and Methods: Sixty adult male rats, weighing 250-200 g randomly divided into four groups (three experimental groups and one co...
متن کاملRadioprotective effect of thymol against salivary glands dysfunction induced by ionizing radiation in rats
The aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. The rats were treated with thymol at dose of 50 mg/Kg before exposure to radiation at dose 15Gy. Salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...
متن کاملImpact of Ionizing Radiation on the Expression of CDC25A Phosphatase (in vivo)
Background and Objective: The cell division cycle 25 (CDC25)is a familyof highly conserved dual-specificity phosphatases that activate cyclin-dependent kinase complexes. These complexes are the main cell cycle regulators. Mammalian cells ,exposure to DNA damaging radiations such as ionizing radiation and ultraviolet light, prevent cell cycle progression by activation of checkpoint pathways an...
