Abstract :
Haberlea rhodopensis leaf extract (HR) possess strong antioxidant activity. The present study aimed to examine the radioprotective potentiality and efficacy of HR against DNA damage induced by γ-irradiation to dose range 1.0-3.0 Gy. HR total extract (0.12 g/kg b. w.) was injected im, into rabbits 2h before whole body irradiation. Rabbits were exposed to 1.0, 2.0 and 3.0 Gy 60Co γ-rays. The radiation-induced changes were estimated by using cytokinesis blocked micronucleus assay (CBMN) in peripheral lymphocytes. Results reveled that the micronucleus test pointed out a significant difference between groups received HR before irradiation and γ-irradiated groups. It was concluded that HR extract was effective in the protection against clastogenic effect of radiation due to its content of different antioxidant ingredients and their ability to scavenge free radicals generated by radiation.
