Genotoxic and inflammatory effects of depleted uranium particles inhaled by rats.
Depleted uranium (DU) is a radioactive heavy metal coming from the nuclear industry and used in numerous military applications. Uranium inhalation can lead to the development of fibrosis and neoplasia in the lungs. As little is known concerning the molecular processes leading to these pathological effects, some of the events in terms of genotoxicity and inflammation were investigated in rats ex...
متن کاملDistribution of uranium in rats implanted with depleted uranium pellets.
During the Persian Gulf War, soldiers were injured with depleted uranium (DU) fragments. To assess the potential health risks associated with chronic exposure to DU, Sprague Dawley rats were surgically implanted with DU pellets at 3 dose levels (low, medium and high). Biologically inert tantalum (Ta) pellets were used as controls. At 1 day and 6, 12, and 18 months after implantation, the rats w...
متن کاملMitochondrial Toxicity of Depleted Uranium: Protection by Beta-Glucan
Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...

متن کاملDepleted Uranium and Its Effects on Humans
The article summarizes contemporary scientific knowledge of depleted uranium effects on human health due to its use in military conflicts. The discussion covers cases of minimal risk due to external irradiation resulting from the storage and handling of depleted uranium ammunition and, in contrast, important toxicological and radio-toxicological risks of late effects resulting from the inhalati...
