This study showed the protective effect of polydatin (PD), which has an antioxidant activity against oxidative stress in mice caused by aflatoxin B (AFB). In this study, 36 male Swiss albino mice were divided equally into 6 groups: 0.2 mL of FTS was administered to the control group, 0.2 mL of olive oil to the second group, and 0.75 mg/kg AFB to the third group by intragastric gavage every day for 28 days. The fourth, fifth, and sixth groups were administered 50, 100, and 200 mg/kg PD and 0.75 mg/kg AFB intragastrically for 28 days, respectively. AFB administration increased plasma aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, blood urea nitrogen, creatinine, and malondialdehyde levels in blood and tissue samples but decreased the level of glutathione and the activities of superoxide dismutase and catalase. On the other hand, it was determined that PD applications depending on the increasing doses brought these levels closer to normal. In addition, AFB administration increased the amount of ssDNA and liver COX-2, TNF-α, IL-6, NFκB, and Cyp3a11 mRNA expression levels; on the other hand, it decreased the IL-2 mRNA expression level. In contrast, increasing doses of PD application regulated the amount of ssDNA and these mRNA expression levels. Additionally, histopathological damage was observed in the liver and kidney tissues of the AFB group, while PD applications in a dose-dependent manner improved these damages. As a result, it was determined that PD reduced AFB-induced oxidative stress, DNA damage, and inflammation and exhibited a protective effect on tissues in mice.
本研究显示了虎杖苷(PD)的保护作用,其具有抗氧化活性,可对抗黄曲霉毒素B(AFB)引起的小鼠氧化应激。在本研究中,36只雄性瑞士白化小鼠被平均分为6组:对照组给予0.2 mL FTS,第二组给予0.2 mL橄榄油,第三组每天通过灌胃给予0.75 mg/kg AFB,持续28天。第四、五、六组分别给予50、100和200 mg/kg PD及0.75 mg/kg AFB灌胃28天。给予AFB后,血液和组织样本中的血浆天冬氨酸转氨酶、丙氨酸转氨酶、碱性磷酸酶、血尿素氮、肌酐和丙二醛水平升高,但谷胱甘肽水平以及超氧化物歧化酶和过氧化氢酶的活性降低。另一方面,已确定随着剂量增加的PD应用使这些水平更接近正常。此外,给予AFB增加了单链DNA的量以及肝脏COX-2、TNF-α、IL-6、NFκB和Cyp3a11 mRNA表达水平;另一方面,它降低了IL-2 mRNA表达水平。相比之下,增加剂量的PD应用调节了单链DNA的量以及这些mRNA表达水平。此外,在AFB组的肝脏和肾脏组织中观察到组织病理学损伤,而PD以剂量依赖的方式改善了这些损伤。结果,已确定PD减轻了AFB诱导的氧化应激、DNA损伤和炎症,并对小鼠组织表现出保护作用。
