The radioprotective efficacy of Ferulic acid (FA) against whole body gamma radiation was studied in Swiss albino mice. To study the radiation protection, mice were administered with ferulic acid intraperitoneally (i.p) (50mg/kg body weight.), once daily for five consecutive days. One hour after the last administration of ferulic acid on the sixth day, animals were whole body exposed to 8Gy gamma radiations. Effect of ferulic acid pretreatment on radiation-induced changes in antioxidant enzymes and lipid peroxidation status in spleen, liver and intestine was analyzed. A significant increase in the antioxidant enzymatic status and decreased lipid peroxidation marker levels were observed in ferulic acid pretreated group, when compared to the irradiated animals. Our study also shows increased % tail DNA, tail length, tail moment and Olive tail moment in irradiated mice blood lymphocytes. Ferulic acid (50mg/kg body weight) pretreatment significantly decreased the % tail DNA, tail length, tail moment and Olive tail moment in irradiated mice lymphocytes. The histological observations indicated a decline in the villus height and crypt number with an increase in goblet and dead cell population in the irradiated group, which was normalized by ferulic acid pretreatment. In conclusion, present study indicated ferulic acid treatment prevents radiation-induced lipid peroxidation, DNA damage and restored antioxidant status and histopathological changes in experimental animals.
