Abstract: Whole-body exposure to gamma radiation was found to result in damage to cellular DNA and lowering of antioxidant levels in various tissues. Administration of POLY-MVA, a palladium-lipoic acid formulation, for seven days prior to whole body gamma radiation significantly reduced the damage to cellular DNA in bone marrow and blood leukocytes, as well as preventing the radiation-induced lowering of tissue antioxidant levels.

Keywords: antioxidant defence; DNA damage; comet assay; POLY-MVA; palladium-lipoic acid complex; dietary supplements; radioprotector; radioprotection; gamma radiation; bone marrow; blood leukocytes; cellular DNA.
