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) (50 mg/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 8 Gy 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 (50 mg/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.
阿魏酸(FA)对全身γ射线的放射防护作用在瑞士白化小鼠中进行了研究。为了研究放射防护作用,将阿魏酸经腹腔(i.p)给予小鼠(50mg/kg 体重),每天一次,连续 5 天。在第六天最后一次给予阿魏酸后 1 小时,对动物进行全身 8Gyγ射线照射。分析了阿魏酸预处理对辐射诱导的脾、肝和肠抗氧化酶和脂质过氧化状态变化的影响。与辐射动物相比,阿魏酸预处理组观察到抗氧化酶状态显著增加,脂质过氧化标志物水平降低。我们的研究还表明,辐照小鼠血液淋巴细胞中的%尾 DNA、尾长、尾矩和 Olive 尾矩增加。阿魏酸(50mg/kg 体重)预处理显著降低了辐照小鼠淋巴细胞中的%尾 DNA、尾长、尾矩和 Olive 尾矩。组织学观察表明,照射组绒毛高度和隐窝数量下降,杯状细胞和死亡细胞数量增加,阿魏酸预处理使其正常化。总之,本研究表明,阿魏酸治疗可预防辐射诱导的脂质过氧化、DNA 损伤,并恢复实验动物的抗氧化状态和组织病理学变化。
