Abstract:
ObjectiveTo investigate the attenuating effect of Dioscoreae Bulbiferae Rhizoma（DBR） processed with Phaseoli Radiati Semen（PRS） juice， and explore the attenuating mechanism based on ferroptosis of the main toxic target organ. MethodSixty male ICR mice were randomly divided into blank group， DBR group， water roasted DBR group（hereinafter referred to as water group）， PRS juice-roasted DBR group 1（DBR-PRS 10∶1， stuffy moistening for 40 min， stir-fried at 130 ℃ for 18 min， hereinafter referred to as group 1）， PRS juice-roasted DBR group 2（DBR-PRS 10∶1， stuffy moistening for 80 min， stir-fried at 100 ℃ for 14 min， hereinafter referred to as group 2）， PRS juice-roasted DBR group 3（DBR-PRS=20∶3， stuffy moistening for 40 min， stir-fried at 160 ℃ for 14 min， hereinafter referred to as group 3）. The raw and processed groups of DBR were gavaged with their corresponding 95% ethanol extract at a dose of 3 g·kg-1·d-1， while the blank group was gavaged with an equal volume of 0.5% sodium carboxymethyl cellulose， once a day for 14 consecutive days. Hematoxylin-eosin（HE） staining was used to observe the histopathological changes of mouse liver. Alanine aminotransferase（ALT） and aspartate aminotransferase（AST） levels in serum， as well as malondialdehyde（MDA）， ferrous ions（Fe2+）， reduced glutathione（GSH） and superoxide dismutase（SOD） levels in liver tissue were detected by the biochemical detection. Western blot was used to detect the expression of iron key proteins such as ferritin heavy chain 1（FTH1） and glutathione peroxidase 4（GPX4）. ResultHE staining results showed that the liver tissue structure of the blank group was clear， the morphology of hepatocytes was normal， the cytoplasms of hepatocytes in the DBR group and water group were loose and vacuolar， with obvious pathological damages， and the pathologic damages of mice in the group 1-3 were significantly improved. Compared with the blank group， the levels of ALT， AST， MDA and Fe2+ in mice from the DBR group were significantly increased（P<0.01）， while GSH and SOD levels were significantly reduced（P<0.01）， and the protein expression levels of FTH1 and GPX4 were significantly decreased（P<0.01）. Compared with the DBR group， the ALT， AST，MDA and Fe2+ levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the GSH and SOD levels and the protein expression levels of FTH1 and GPX4 were significantly increased（P<0.01）. Compared with the water group， the AST and MDA levels of mice in the group 1-3 were significantly reduced（P<0.05， P<0.01）， the SOD level significantly increased（P<0.05， P<0.01）， the FTH1 protein expression significantly increased（P<0.01）， and the serum ALT level of mice in the group 2-3 significantly reduce（P<0.01）， Fe2+ level significantly reduced（P<0.01）， GSH level significantly increased（P<0.05， P<0.01）， and GPX4 protein expression significantly increased（P<0.05， P<0.01）. Among the group 1-3， the group 3 had the best detoxification effect. ConclutionProcessing with PRS juice can reduce the liver injury induced by DBR， and the mechanism may be related to the inhibition of ferroptosis in the liver.
