PURPOSE These comments suggest a division of radiation protective agents on the grounds of their mechanism of action that increase the radio resistance of an organism. CONCLUSION Given below is the division of radiation protective agents on the basis of their mechanism of action into 3 groups: 1) Radiation protective agents, with the implementation of radiation protective action taking place ...

introduction it has long been known that ionizing radiation can lead to detrimental effects in normal cells. in this light, radioprotective chemicals have been used to decrease morbidity or mortality caused by ionizing irradiation. this study aimed to evaluate the radio-protective effect of n-acetylcysteineagainst radiation-induced mortality in male mice. materials and methods 52 healthy male m...

Objective: Ionizing radiation induces deleterious effects in the biological systems by producing free radicals. Grape Seed Extract (GSE) as a free radical scavenger could protect the body against the damages. Materials and Methods: In this study, 12 healthy male volunteers were divided into Groups 1, 2, 3 and 4 and received 100, 300, 600 and 1000...

Herbal plants and products represent important source of natural antioxidant offer an alternative to synthetic protectors. Moringa oliefera, a herbal medicinal plant has been screen for their radioprotective activity. For the purpose study male Swiss albino mice were divided into seven groups. The exposed gamma radiation (2.5 Gy 5.0 Gy) also provided mercuric chloride (0.5 ppm) both separately ...

The radioprotective activity of Piper betel ethanolic extract (PE) has been studied using rat liver mitochondria and pBR 322 plasmid DNA as two model in vitro systems. The extract effectively prevented gamma-ray induced lipid peroxidation as assessed by measuring thiobarbituric acid reactive substrates, lipid hydroperoxide and conjugated diene. Likewise, it prevented radiation-induced DNA stran...

New analogues of the minor groove binding ligand Hoechst 33342 have been investigated in an attempt to improve radioprotective activity. The synthesis, DNA binding, and in vitro radioprotective properties of methylproamine, the most potent derivative, are reported. Experiments with V79 cells have shown that methylproamine is approximately 100-fold more potent than the classical aminothiol radio...
