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.

Acremoniumterricola milleretal mycelium (AMM) is one of the most precious traditional Chinese medicines. It has numerous protective effects on organs, and has been used in Chinese herb prescription to treat refractory diseases. Our preliminary studies demonstrated that AMM had hepatoprotective activity in acute liver injury. We further investigated the effects of AMM on liver fibrosis in rats induced by carbon tetrachloride ( CCl 4) and explore its possible mechanisms. The animal model was established by injection with 50% CCl 4 subcutaneously in male Sprague-Dawley rats twice a week for eight weeks. Meanwhile, AMM (175, 350 and 700 mg/kg) was administered intragastrically per day until sacrifice. We found that treatment with AMM (175, 350 and 700 mg/kg) decreased CCl 4-induced elevation of serum transaminase activities, hyaluronic acid, laminin and procollagen type III levels, and contents of hydroxyproline in liver tissues. It also restored the decreased SOD and GSH-Px activities and inhibited the formation of lipid peroxidative products during CCl 4 treatment. Moreover, AMM (350 and 700 mg/kg) decreased the elevation of TGF-β1 by 19.6% and 34.3%, respectively. In the pathological study, liver injury and the formation of liver fibrosis in rates treated by AMM were improved significantly. Immunoblot analysis showed that AMM (175, 350 and 700 mg/kg) inhibited Smad 2/3 phosphorylation, and elevated inhibitor Smad 7 expression. These results suggested that AMM could protect liver damage and inhibit the progression of hepatic fibrosis induced by CCl 4, and its mechanisms might be associated with its ability to scavenge free radicals, decrease the level of TGF-β1 and block TGF-β/Smad signaling pathway.

Preventive Effect

To examine the mechanism of the preventive effect of tannins on the progression of carbon tetrachloride (CCl4)-induced acute liver injury in rats, sumac gall (SG) extract and gallic acid (GA) were used as substitutes for crude tannins, because SG is a kind of Chinese traditional medicinal herb containing large amounts of various tannins, and GA is one of the major constituents of SG. The protective effect of oral (p.o.) and intraperitoneal (i.p.) administration of each substance on progression of CCl4-induced hepatitis was investigated in rats. Speculating that the superoxide dismutase (SOD)-like activities (O2 radical-scavenging activities) and/or protective effects of these substances on cell membranes might play a key role in the mechanism opposing the progression of CCl4-induced hepatitis, the O2 radical-scavenging activities in liver cells and serum in rats were monitored. Both substances significantly prevented the progression of acute liver injury with both p.o. and i.p. administration. These findings suggest that the mechanism for this prevention might be due mainly to the protective effect of these substances on cell membranes rather than O2 radical-scavenging activities.

Introduction: Liver fibrosis is one of the most common clinical manifestations of hepatic diseases. However, though many synthetic drugs exist for the treatment and prevention of liver diseases, liver injuries still persist. The present study, therefore, sought to investigate the subacute protective effects of Acalphya wilkesiana against carbon tetrachloride (CCl4)-induced toxicity in animals. Methodology: Liver injury was induced in experimental animals by administering CCl4 (1:1 v/v in olive oil, intraperitoneally (i.p.), twice weekly for 8 weeks) after pre-treatment with extract of A. wilkesiana (AWE). AWE (250 mg/kg) and Silymarin (120 mg/kg) were administered orally (daily for 8 weeks). The hepatoprotective effect was studied by assaying the activity of liver enzymes, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and alpha-fetoprotein. The effect of the treatments on liver prooxidants (e.g. malondialdehyde [MDA]) and antioxidants (e.g. superoxide dismutase [SOD], reduced glutathione [GSH], glutathione peroxidase [GPx], and glutathione transferase [GST]), as well as inflammatory cytokines (e.g. interleukin [IL]-17, IL-23, nuclear factor kappa beta [NF-kB], and cycloxygenase-1 [COX-1]) and the histology of the liver were also examined. Results: The activity of liver function biomarkers changed significantly upon CCl4 administration; increases in ALT, total and direct bilirubin, and some fibrosis indices (e.g. alpha-fetoprotein and APRI [p<0.05-0.001, compared with normal]) were observed. Co-administration of AWE with CCl4 restored these to normal levels. The intensity of structural alterations revealed that the AWE treatment has protective potential against subacute liver injury. AWE treatment also reduced the expression of IL-17, 1L-23, NF-kB and COX-1, underscoring its antiinflammatory properties. Conclusion: The results of the current study generally suggest that hydroethanolic leaf extracts of A. wilkesiana inferno possess some subacute protective activity by improving liver function and inhibition of inflammation, and could be developed as a potent antifibrotic agent.
