Assessment in vitro of radioprotective efficacy of curcumin and resveratrol

Abstract Many natural substances have been studied in recent past to be used as radioprotectors to mitigate ionizing radiation-induced damage in mammalian systems due to its effectiveness given both pre- and post-irradiation and for long time with out drug-related toxicity. Curcumin and trans -resveratrol are both natural occurring polyphenols, obtained from the root of Curcuma longa and from grapes and other berries, respectively. These compounds have shown antioxidant, anti-inflammatory, immunostimulant and anti-carcinogenic properties. Our aim was to evaluate the radioprotective efficacy, in vitro , of curcumin and trans -resveratrol separately against radiation-induced chromosomal aberr…
