mitochondrial toxicity of depleted uranium: protection by beta-glucan
نویسندگان
چکیده
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-induced mitochondrial reactive oxygen species (ros) formation, lipid peroxidation and glutathione oxidation. beta-glucan and bht also prevented the loss of mitochondrial membrane potential (mmp) and mitochondrial swelling following the ua treatment in isolated mitochondria. our results show that beta-glucan and bht prevented ua-induced mitochondrial outer membrane damage as well as release of cytochrome c from mitochondria. ua also decreased the atp production in isolated mitochondria significantly inhibited with beta-glucan and bht pre-treatment. our results showed that beta-glucan may be mitochondria-targeted antioxidant and suggested this compound as a possible drug candidate for prophylaxis and treatment against du-induced nephrotoxicity.

متن کاملThe Toxicity of Depleted Uranium
Depleted uranium (DU) is an emerging environmental pollutant that is introduced into the environment primarily by military activity. While depleted uranium is less radioactive than natural uranium, it still retains all the chemical toxicity associated with the original element. In large doses the kidney is the target organ for the acute chemical toxicity of this metal, producing potentially let...

Introduction: Recently depleted uranium is being widely used as anti-armour ammunition and at very high temperature, results in information of an aerosol of very small uranium oxide particles, which may be inhaled. It is alleged that these particles represent a new battlefield hazard because of the chemical toxicology and/or radioactivity. Method & materials: Male Wistar strain albino rats ...
