Radioprotection of Swiss albino mice byEmblica officinalis

Abstract

The fruit pulp of Emblica officinalis (EO) is an important drug used in Indian systems of medicine for several diseases and as a tonic. In view of its multifarious uses, the plant extract (aqueous) was tested for its radioprotective properties against sublethal gamma radiation (9 Gy) in Swiss albino mice. Animals were divided into two groups and irradiated with gamma radiation externally, with or without EO extract, which was given orally at different doses before irradiation. The dose of fruit pulp extract found to be most effective against radiation was 100 mg/kg b.wt. This dose increased the survival time and reduced the mortality rate of mice significantly. Furthermore, body weight loss in EO administered irradiated animals was significantly less in comparison with animals who were given radiation only.
