Background: The xenobiotics-induced liver injury is a clinical complication. Hence, finding new hepatoprotective strategies has clinical value. Oxidative stress and its subsequent complications are major mechanisms involved in xenobiotics-induced hepatotoxicity. Boldine is one of the most potent antioxidant molecules widely investigated for its protective properties in different experimental models. In the current study, the hepatoprotective properties of boldine and its potential mechanisms of hepatoprotection have been investigated. Methods: Rats received thioacetamide (TAA; 200 mg/kg, i.p) as a model of acute liver injury. Boldine (5, 10, 1nd 20 mg/kg; 24 hours intervals; oral) was administered as the hepatoprotective agent. Results: Liver injury was evident in TAA-treated animals (48 hours after TAA exposure) as a severe increase in serum level of liver injury biomarkers and histopathological alterations. Moreover, markers of oxidative stress were increased in liver tissue of TAA-treated rats. Assessment of mitochondrial indices of functionality revealed a significant decrease in mitochondrial dehydrogenases activity, the collapse of mitochondrial membrane potential, mitochondrial swelling and depletion of ATP content. It was found that boldine supplementation mitigated liver tissue markers of oxidative stress and improved mitochondrial indices of functionality in TAA-treated animals. Conclusion: The hepatoprotective properties of boldine might primarily rely on antioxidant and mitochondria protecting effects of this alkaloid.

Abstract The objectives of this study were to determine if feeding thermally processed (TP, heated at 100°C for 120 h) spray-dried egg whites (SDEW) to nursery pigs would impact growth performance, apparent total tract digestibility (ATTD) of GE, N, and S, and oxidative stress. Thirty-two barrows, (initial BW 7.1 kg) were randomly assigned to dietary treatments with 1 pig per pen. In a preliminary study, thermally processing SDEW at 100°C for 120 h increased protein carbonyls (PC) from 6 µmol/g to 19.4 µmol/g (P ≤ 0.01). Diets included either 12% SDEW, 6% TP-SDEW plus 6% SDEW, or 12% TP-SDEW. The experiment lasted 24 d for collection of growth performance data, while plasma was collected on d 21 and liver tissue harvested on d 24 to analyze for markers of oxidative stress. Feces were collected on d 22 for measures of ATTD. Daily gain, daily feed intake, feed efficiency, and ATTD of GE were not found to be different among dietary treatments (P ≥ 0.57). In contrast, ATTD of N (P = 0.11) and S (P = 0.03) were found to increase with increasing protein oxidation in the diet. There was no change in the plasma or liver F2-isoprostanes and 8-hydroxy-2’-deoxyguanosine among dietary treatments (P ≥ 0.28). An increase in plasma PC (P = 0.02) was observed in pigs fed 12% TP-SDEW compared to pigs fed 12% SDEW and pigs fed 6% TP-SDEW. In contrast, a decrease in liver tissue PC (P = 0.04) was observed in pigs fed 6% TP-SDEW compared to pigs fed 12% SDEW and 12% TP-SDEW. These results indicate that feeding TP-SDEW does not affect growth performance, ATTD of GE, and oxidative stress as indicated by F2-isoprostanes or 8-hydroxy-2’-deoxyguanosine; but appeared to have variable effects on oxidative stress as measured by PC.

Background. Huangkui capsule (HKC) comprises the total flavonoid extract of flowers of Abelmoschus manihot (L.) Medicus. This study aimed to explore the effects of HKC on lipopolysaccharide- (LPS-) induced acute lung injury (ALI) in mice and LPS-stimulated RAW 264.7 cells. Methods. Enzyme-linked immunosorbent assay, histopathology, spectrophotometry, and quantitative real-time polymerase chain reaction were used for the assessments. Statistical analysis was performed using a one-way analysis of variance. Results. LPS significantly increased lung inflammation, neutrophil infiltration, and oxidative stress and downregulated lung miR-451 expression. Treatment with HKC dramatically attenuated the lung wet/dry weight ratio, reduced the total cell count in the bronchoalveolar lavage fluid (BALF), and inhibited myeloperoxidase activity in the lung tissues 24 h after LPS challenge. Histopathological analysis demonstrated that HKC attenuated LPS-induced tissue oedema and neutrophil infiltration in the lung tissues. Additionally, the concentrations of tumour necrosis factor- (TNF-) α and interleukin- (IL-) 6 in BALF and IL-6 in the plasma reduced after HKC administration. Moreover, HKC could enhance glutathione peroxidase and catalase activities and upregulate the expression of miR-451 in the lung tissues. In vitro experiments revealed that HKC inhibited the production of nitric oxide, TNF-α, and IL-6 in LPS-induced RAW 264.7 cells and mouse primary peritoneal macrophages. Additionally, HKC downregulated LPS-induced transcription of TNF-α and IL-6 in RAW 264.7 cells. Conclusions. These findings suggest that HKC has anti-inflammatory and antioxidative effects that may protect mice against LPS-induced ALI and macrophage activation.

Magnesium Isoglycyrrhizinate

Alcoholic liver disease (ALD) is a leading cause of liver-related morbidity and mortality worldwide. There is no effective treatment to prevent the disease progression. Magnesium isoglycyrrhizinate (MgIG) showed potent anti-inflammatory, antioxidant, and hepatoprotective activities and was used for treating liver diseases in Asia. In this study, we examined whether MgIG could protect mice against alcohol-induced liver injury. The newly developed chronic plus binge ethanol feeding model was used to study the role of MgIG in ALD. Serum liver enzyme levels, H&E staining, immunohistochemical staining, flow cytometric analysis, and real-time PCR were used to evaluate the liver injury and inflammation. We showed that MgIG markedly ameliorated chronic plus binge ethanol feeding liver injury, as shown by decreased serum alanine transaminase and aspartate aminotransferase levels and reduced neutrophil infiltration. The reason may be attributed to the reduced expression of proinflammatory cytokines and chemokines with the treatment of MgIG. The hepatoprotective effect of MgIG was associated with suppression of neutrophil ROS production as well as hepatocellular oxidative stress. MgIG may play a critical role in protecting against chronic plus binge ethanol feeding-induced liver injury by regulating neutrophil activity and hepatic oxidative stress.
