Introduction. The high frequency of chemical poisoning is accompanied by an increase in the absolute number of cases of chemical damage to the liver. There is growing evidence that acute chemical poisoning in Russia is among the leading non-infectious diseases leading to premature death of male and female working-age people. It seems relevant to search for new pharmacological agents with low toxicity and high hepatoprotective activity, which increase the body’s stability under the influence of adverse environmental factors. The use of metabolic action drugs combining antioxidant and antihypoxic activity as hepatoprotectors is promising. The purpose of this study is an experimental evaluation of the hepatoprotective activity of a new composition of oxymethyluracil with succinic and fumaric acids. Material and methods. The composition of 5-hydroxy-6-methyluracil with succinic and fumaric acids was first synthesized at the Ufa Institute of Chemistry. Using the model of acute liver toxic damage with carbon tetrachloride in laboratory animals, the prophylactic effect of a new drug was studied in comparison with heptor (ademetionine). Biochemical and morphological studies of laboratory animals’ biomaterial were conducted. Results. The analysis showed that when using the studied drugs, biochemical parameters were close to the level of control animals. Morphological changes in the liver were less pronounced in the group of animals treated with the new composition, compared with changes in the structure of the liver of animals treated with heptorator (ademetionin). Conclusion. The new composition of 5-hydroxy-6-methyluracil with succinic and fumaric acids has a protective effect on the liver of laboratory animals with the acute toxic effects of carbon tetrachloride, comparable, and in some cases, exceeding the preventive effect of heptoperam (ademetionine).

This study investigates the hepatoprotective activity of ethanol extract from Shidagonglao roots (SDGLEtOH). The hepatoprotective effect of SDGLEtOH(20, 100 and 500 mg/kg) was analyzed on carbon tetrachloride ( CCl4)-induced acute liver injury. Rats pretreated orally with SDGLEtOH(100 and 500 mg/kg) and silymarin (200 mg/kg) for 3 consecutive days prior to the administration of a single dose of 50% CCl4(0.10 ml/100 g of bw, ip) significantly prevented the increases in the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in CCl4-treated rats. Histological analysis also showed that SDGLEtOH(100 and 500 mg/kg) and silymarin reduced the incidence of liver lesions including vacuole formation, neutrophil infiltration and necrosis of hepatocytes induced by CCl4in rats. Moreover, the SDGLEtOH(100 and 500 mg/kg) increased the activities of anti-oxidative enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GRd) and decreased malondialdehyde (MDA) level in liver, as compared to those in the CCl4-treated group. Furthermore, SDGLEtOH(100 and 500 mg/kg) and silymarin attenuated the increased levels of tumor necrosis factor-α (TNF-α) in serum and nitric oxide ( NO ) in liver as compared to the CCl4-treated group. The hepatoprotective mechanisms of SDGLEtOHare likely related to inhibition of TNF-α, MDA and NO productions via increasing the activities of antioxidant enzymes (SOD, GPx and GRd). These experimental results suggest that SDGLEtOHcan attenuate CCl4-induced acute liver injury in rats.

Hepatoprotective Effects

Background and Objective : A Tibetan traditional herb named Swertia mussotii Franch., also called “Zangyinchen” by the local people of Qinghai-Tibet area, has been used to protect the liver from injury for many years. However, the curative effect and molecular mechanism of the herb have not been demonstrated clearly. Materials and Methods: In our study, serum alanine aminotransferase, aspartate aminotransferase, total bilirubin levels were examined after S. mussotii Franch. treatment in the acute liver injury of the carbon tetrachloride-induced rat model. Then, Proteome Analysis was applied to explore the potential mechanism of SMT for hepatoprotective effects after iTRAQLC-MS/MS analysis (isobaric tag for relative and absolute quantification-liquid chromatograph-mass spectrometer with tandem mass spectrometry). Results: Serum results showed, alanine aminotransferase, aspartate aminotransferase, total bilirubin levels of rats with acute liver injury were all improved with SMT treatment. Moreover, Proteome Analysis suggested that, with S. Mussotii Franch. treatment, the levels of lipid catabolic process and lipid homeostasis were all enhanced. And the results of protein-protein interaction (PPI) analysis illustrated that these proteins assembled in PPI networks were found almost significantly enriched in response to lipid, negative regulation of lipase activity, response to lipopolysaccharide etc. Furthermore, the downregulated MRP14 and MRP8 proteins were found involved in the lipid metabolism, which may indicate the mechanism of SMT protection liver from ALI induced by carbon tetrachloride. Conclusion: SMT herb could play a role in hepatoprotection and alleviate the effect of acute liver injury by impacting the lipid metabolism associated biological process.

Lemon Balm

Lemon balm and dandelion are commonly used medicinal herbs exhibiting numerous pharmacological activities that are beneficial for human health. In this study, we explored the protective effects of a 2:1 (w/w) mixture of lemon balm and dandelion extracts (MLD) on carbon tetrachloride (CCl4)-induced acute liver injury in mice. CCl4 (0.5 mL/kg; i.p.) injection inhibited body weight gain and increased relative liver weight. Pre-administration of MLD (50–200 mg/kg) for 7 days prevented these CCl4-mediated changes. In addition, histopathological analysis revealed that MLD synergistically alleviated CCl4-mediated hepatocyte degeneration and infiltration of inflammatory cells. MLD decreased serum aspartate aminotransferase and alanine transferase activities and reduced the number of liver cells that stained positive for cleaved caspase-3 and cleaved poly(ADP-ribose) polymerase, suggesting that MLD protects against CCl4-induced hepatic damage via the inhibition of apoptosis. Moreover, MLD attenuated CCl4-mediated lipid peroxidation and protein nitrosylation by restoring impaired hepatic nuclear factor erythroid 2-related factor 2 mRNA levels and its dependent antioxidant activities. Furthermore, MLD synergistically decreased mRNA and protein levels of tumor necrosis factor-α, interleukin-1β, and interleukin-6 in the liver. Together, these results suggest that MLD has potential for preventing acute liver injury by inhibiting apoptosis, oxidative stress, and inflammation.
