Abstract
Fulminant hepatitis (FH) is a severe clinical syndrome leading to hepatic failure and even mortality. D-galactosamine (D-GalN) plus lipopolysaccharide (LPS) challenge is commonly used to establish an FH mouse model, but the mechanism underlying D-GalN/LPS-induced liver injury is incompletely understood. Previously, it has been reported that extracellular ATP that can be released under cytotoxic and inflammatory stresses serves as a damage signal to induce potassium ion efflux and trigger the NACHT, LRR and PYD domains-containing protein 3 (NLRP3) inflammasome activation through binding to P2X7 receptor. In this study, we tried to investigate whether it contributed to the fulminant hepatitis (FH) induced by D-GalN plus LPS. In an in vitro cellular model, D-GalN plus extracellular ATP, instead of D-GalN alone, induced pyroptosis and apoptosis, accompanied by mitochondrial reactive oxygen species (ROS) burst, and the oligomerization of Drp1, Bcl-2, and Bak, as well as the loss of mitochondrial membrane potential in LPS-primed macrophages, well reproducing the events induced by D-GalN and LPS in vivo. Moreover, these events in the cellular model were markedly suppressed by both A-804598 (an ATP receptor P2X7R inhibitor) and glibenclamide (an ATP-sensitive potassium ion channel inhibitor); in the FH mouse model, administration of A-804598 significantly mitigated D-GalN/LPS-induced hepatic injury, mitochondrial damage, and the activation of apoptosis and pyroptosis signaling, corroborating the contribution of extracellular ATP to the cell death. Collectively, our data suggest that extracellular ATP acts as an autologous damage-associated molecular pattern to augment mitochondrial damage, hepatic cell death, and liver injury in D-GalN/LPS-induced FH mouse model.

Abstract
This study investigated the hepatoprotective effects of Juncus effusus (J. effusus) and Carbonized J. effusus against liver injury caused by D-galactosamine (D-GalN) in mice. J. effusus and Carbonized J. effusus were administered by gavage once daily starting seven days before the D-GalN treatment. The results of the study indicated that J. effusus and Carbonized J. effusus suppressed the D-GalN-induced generation of serum alanine transaminase (ALT), aspartate aminotransferase (AST), hepatic malondialdehyde (MDA) and tumor necrosis factor-alpha (TNF-α) was observed. The values of superoxide dismutase (SOD) exhibited an increase. In addition, J. effusus and Carbonized J. effusus promoted the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2), NADPH quinone oxidoreductase-1 (NQO-1), heme oxygenase-1 (HO-1) as well as the mRNA expression of Nrf2, HO-1, NQO-1 and Glutamate cysteine ligase catalytic subunit (GCLC). The compressed Carbonized J. effusus demonstrated the optimum impact. These results suggest that J. effusus and Carbonized J. effusus protect against D-GalN-induced acute liver injury through the activation of the Nrf2 pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Acute-on-chronic liver failure (ACLF) progresses rapidly with a high short-term death rate. Although JianPi LiShi YangGan formula (YGF) has been used to treat ACLF by managing inflammatory responses and reducing endotoxemia, hepatocyte injury, and mortality, the underlying mechanisms remain unclear. AIM OF THE STUDY This study aims to investigate the potential mechanisms underlying the efficacy and protective benefits of YGF in mice with ACLF. MATERIALS AND METHODS YGF composition was determined using high-performance liquid chromatography coupled with mass spectrometry. We constructed a mouse model of ACLF using carbon tetrachloride, lipopolysaccharide (LPS), and D-galactosamine (D-Gal), as well as an in vitro model of D-Gal/LPS-induced hepatocyte injury. The therapeutic effects of YGF in ACLF mice were verified using hematoxylin-eosin, Sirius red, and Masson staining, and by measuring serum alanine transaminase (ALT), aspartate transaminase (AST), and inflammatory cytokine levels. Mitochondrial damage in hepatocytes was evaluated using electron microscopy, while superoxide anion levels in liver tissue were investigated using dihydroethidium. Transcriptome analysis, immunohistochemistry, western blotting, and immunofluorescence assays were performed to explore the mechanisms underlying the ameliorative effects of YGF against ACLF. RESULTS In mice with ACLF, YGF therapy partially decreased serum inflammatory cytokine levels, as well as hepatocyte injury and liver fibrosis. The livers of ACLF mice treated with YGF exhibited decreased mitochondrial damage and reactive oxygen species generation, as well as a decreased number of M1 macrophages and increased number of M2 macrophages. Transcriptome analysis revealed that YGF may regulate biological processes such as autophagy, mitophagy, and PI3K/AKT signaling. In ACLF mice, YGF promoted mitophagy and inhibited PI3K/AKT/mTOR pathway activation in hepatocytes. Meanwhile, the autophagy inhibitor 3M-A reduced the capacity of YGF to induce autophagy and protect against hepatocyte injury in vitro. In contrast, the PI3K agonist 740 Y-P suppressed the ability of YGF to control PI3K/AKT/mTOR pathway activation and induce autophagy. CONCLUSIONS Together, our findings suggest that YGF mediates autophagy, tight junctions, cytokine generation, and other biological processes. In addition, YGF inhibits hepatic inflammatory responses and ameliorates hepatocyte injury in mice with ACLF. Mechanistically, YGF can promote mitophagy to ameliorate acute-on-chronic liver failure by inhibiting the PI3K/AKT/mTOR pathway.

Abstract
The pathogen-associated molecular patterns (PAMPs) lipopolysaccharide (LPS) and zymosan, derived from gram-negative bacteria and fungi, respectively, activate the innate immune system and cause injury to multiple organs, including the liver and intestine, in mammals. In rodents, PAMP-induced injury has been demonstrated to be potentiated by co-administration of D-galactosamine (D-GalN) in rodents. However, whether PAMPs and D-GalN collectively cause organ injury in birds remains unclear. The present study aimed to measure the effects of intraperitoneal injection of D-GalN with LPS or zymosan on parameters related to hepatic injury in chicks (Gallus gallus). Plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) activities were not affected by intraperitoneal injection of D-GalN alone. Although these activities were not affected by LPS injection alone, they were increased by combining LPS with D-GalN. In contrast, plasma AST, ALT, and LDH activities were not affected by zymosan, both alone and with D-GalN. The expression of mRNAs for interleukin-6 (IL-6) and inducible nitric oxide synthase (iNOS) in the liver was significantly increased by the combination of LPS and D-GalN. In contrast, combining zymosan with D-GalN significantly increased iNOS mRNA expression, irrespective of hepatic injury. These results suggest that IL-6 may be the cause and/or result of hepatic injury in chicks. Additionally, chicks are tolerant to the hepatic effects of D-GalN, LPS, or zymosan alone.

Abstract
Introduction Hepatic inflammation is considered key driver of hepatic tissue impairment.We aimed to explore the interaction of Halamphora coffeaeformis (Amph.) with low dose ionizing γ radiation (γR) exposure against D-galactosamine (D-GaIN)-induced chronic hepatitis in Albino rats. Methods Chronic hepatitis was induced with single dose of D-GalN (400 mg/kg BW i.p.). Rats received 400 mg Amph/kg BW daily by gastric gavage concomitant with .25 Gy γ-R. Liver oxidative stress and inflammatory status were assessed. Gene expression levels of signal transducer and activator of transcription 3 (STAT3) and nuclear factor kappa B (NFKB) were estimated by q-PCR. D-Galactosamine injection significantly encouraged hepatic oxidative damage and inflammatory disturbance accompanied with improved intercellular adhesion molecule-1 level (ICAM-1). Results messenger RNA gene expression levels of STAT3 and NF-kB were expressively higher in D-GaIN-treated animals. Histopathological examination supported results. Interestingly, Amph treatment with γ-radiation (γ-R) subjection displayed significant improvement of oxidative and inflammatory status along with controlled signaling molecular factors which was supported by amended histological structure of induced liver hepatitis. Conclusion Results conclude the efficacious control of liver hepatitis progression by dual collaboration of Amph. with low dose γ-R via control of vital growth signaling factors linked with inflammation thru anti-inflammation, antioxidative and anti-proliferative activities.

Abstract
Fulminant hepatitis remains a critical health problem owing to its high mortality rate and the lack of effective therapies. An increasing number of studies have shown that glutamine supplementation provides protective benefits in inflammation-related disorders, but the pharmacological significance of glutamine in lipopolysaccharide (LPS)/D-galactosamine (D-Gal)-induced fulminant hepatitis remains unclear. In the present study, the potential effects of glutamine on LPS/D-Gal-induced fulminant hepatitis were investigated. Pretreatment with glutamine decreased plasma activities of alanine and aspartate aminotransferases, and ameliorated hepatic morphological abnormalities in LPS/D-Gal-exposed mice. Glutamine pretreatment also inhibited LPS/D-Gal-induced tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) production. In addition, glutamine pretreatment decreased the level of cleaved cysteinyl aspartate-specific proteinase 3 (caspase-3), suppressed the activities of caspase-3, caspase-8, and caspase-9, and reduced the number of cells positive for TdT-mediated dUTP nick-end labeling in LPS/D-Gal-challenged mice. Interestingly, post-treatment with glutamine also provided protective benefits against LPS/D-Gal-induced acute liver injury, although these effects were less robust than those of glutamine pre-treatment. Thus, glutamine may have potential value as a pharmacological intervention in fulminant hepatitis.

Abstract
Levosimendan, a calcium sensitizer, has an organ protective profile through the inhibition of inflammatory mediators and cytokines in critical conditions, such as heart failure, ischemia-reperfusion injury, and sepsis. The survival effect of levosimendan for acute liver failure has not been examined yet. Male Sprague-Dawley rats were examined in the D-galactosamine hydrochloride and lipopolysaccharide (GalN/LPS) model. Levosimendan was injected intraperitoneally before GalN/LPS treatment. Survival was monitored for 7 days. For biochemical analyses, liver and blood samples were collected from the rats at 1 and 8 h after GaIN/LPS treatment. The pretreatment of levosimendan at 4 mg/kg significantly increased survival in GalN/LPS rats. In the liver specimen, levosimendan significantly inhibited the activation of nuclear factor-κB (NF-κB) at 1 h, and significantly decreased the mRNA expression of inflammatory mediators, including inducible nitric oxide synthase and tumor necrosis factor-α (TNF-α), at 8 h. In serum, levosimendan decreased the levels of nitrite, a metabolite of nitric oxide, and TNF-α protein, as well as aspartate aminotransferase and alanine aminotransferase. These results indicated that Levosimendan ameliorated liver dysfunction and survival in acute liver failure model rats through the suppression of NF-κB activation.

Abstract
OBJECTIVES The present research focused on estimating, for the first time, the potential protective effects of bromelain against D-galactosamine-induced acute liver injury in rats as well as identifying the possible underlying mechanisms. METHODS Silymarin (100 mg/kg/day, p.o.) as a reference drug or bromelain (20 and 40 mg/kg/day, p.o.) were administered for 10 days, and on the 8th day of the experiment, a single dose of galactosamine (400 mg/kg/i.p.) induced acute liver injury. KEY FINDINGS Pretreatment with bromelain improved liver functions and histopathological alterations induced by galactosamine. Bromelain ameliorated oxidative stress by inducing SIRT1 protein expression and increasing LKB1 content. This resulted in phosphorylating the AMPK/GSK3β axis, which stimulated Nrf2 activation in hepatic cells and thus increased the activity of its downstream antioxidant enzymes [HO-1 and NQO1]. Besides, bromelain exerted significant anti-apoptotic and anti-inflammatory effects by suppressing hepatic contents of TNF-α, NF-κB p65, as well as caspase-8 and caspase-9. The protective effects of bromelain40 were proved to be better than silymarin and bromelain20 in most of the assessed parameters. CONCLUSIONS Our results highlight the significant hepatoprotective effects of bromelain against acute liver injury through modulation of SIRT1/LKB1/AMPK, GSK3β/Nrf2 signalling in addition to NF-κB p65/TNF-α/ caspase-8 and -9 pathway.

Abstract
Nerve injury‐induced protein 1 (Ninjurin1, Ninj1) is a membrane protein that mediates cell adhesion. The role of Ninj1 during inflammatory response has been widely investigated in macrophages and endothelial cells. Ninj1 is expressed in various tissues, and the liver also expresses high levels of Ninj1. Although the hepatic upregulation of Ninj1 has been reported in human hepatocellular carcinoma and septic mice, little is known of its function during the pathogenesis of liver diseases. In the present study, the role of Ninj1 in liver inflammation was explored using lipopolysaccharide (LPS)/D‐galactosamine (D‐gal)‐induced acute liver failure (ALF) model. When treated with LPS/D‐gal, conventional Ninj1 knock‐out (KO) mice exhibited a mild inflammatory phenotype as compared with wild‐type (WT) mice. Unexpectedly, myeloid‐specific Ninj1 KO mice showed no attenuation of LPS/D‐gal‐induced liver injury. Whereas, Ninj1 KO primary hepatocytes were relatively insensitive to TNF‐α‐induced caspase activation as compared with WT primary hepatocytes. Also, Ninj1 knock‐down in L929 and AML12 cells and Ninj1 KO in HepG2 cells ameliorated TNF‐α‐mediated apoptosis. Consistent with in vitro results, hepatocyte‐specific ablation of Ninj1 in mice alleviated LPS/D‐gal‐induced ALF. Summarizing, our in vivo and in vitro studies show that lack of Ninj1 in hepatocytes diminishes LPS/D‐gal‐induced ALF by alleviating TNF‐α/TNFR1‐induced cell death.

Abstract
Acute liver failure (ALF), characterized by the quick occurrence of disorder in liver, is a serious liver injury with extremely high mortality. Therefore, we investigated whether diallyl trisulfide (DATS), a natural product from garlic, protected against ALF in mice and studied underlying mechanisms. In the present study, lipopolysaccharide (LPS) (10 μg·kg-1)/D-galactosamine (D-gal) (500 mg·kg-1) was intraperitoneally injected to ICR mice to induce ALF. The mice were orally administered 20-, 40-, or 80-mg·kg-1 DATS) 1 h before LPS/D-gal exposure. Serum biochemical analyses and pathological study found that DATS pretreatment effectively prevented the ALF in LPS/D-gal-treated mice. Mechanistically, pretreatment of DATS inhibited the increase of the numbers of CD11b+ Kupffer cells and other macrophages in the liver, the release of tumor necrosis factor-α into the blood, and Caspase-1 activation induced by LPS/D-gal treatment in mice. Furthermore, DATS inhibited the activation of Caspase-3, downregulation of Bcl-2/Bax ratio, and increase of TUNEL positive staining. Altogether, our findings suggest that DATS exhibits hepatoprotective effects against ALF elicited by LPS/D-gal challenge, which probably associated with anti-inflammation and anti-apoptosis.

Abstract
BACKGROUND AND PURPOSE Oridonin (Ori) has been shown to protect against acute liver injury (ALI) induced by D-galactosamine (D-GalN) and lipopolysaccharide (LPS). Oxylipins are oxidation products of polyunsaturated fatty acids (PUFAs) and are key proinflammatory mediators. This study aimed to investigate the changes in oxylipins in the livers of mice with D-GalN/LPS-induced ALI and the effects of Ori on these changes. RESULTS 54 oxylipins in liver tissues were identified and qualitatively and quantitatively analyzed by ultra-performance liquid chromatography-electrospray ionization triple quadrupole mass spectrometry (UPLC-QTRAP/MS/MS). The levels of 12-HETE, 12-HEPE, 14(S)-HDHA, PGE2, dihomo-γ-linolenic acid and 13-HOTrE in the liver were significantly increased in the D-GalN/LPS-induced ALI group compared with the control group, and the levels of EPA and 7-HDHA were significantly decreased. However, pretreatment with Ori dramatically decreased the levels of 12-HETE, 12-HEPE, 14(S)-HDHA, PGE2 and 13-HOTrE compared with those of the ALI group and induced 7-HDHA and 15-oxoETE. Moreover, Ori reduced the protein levels of COX-1, COX-2, ALOX5, ALOX12 and ALOX15 induced by D-GalN/LPS, indicating that Ori altered oxylipins through the COX and LOX pathways. CONCLUSIONS These results suggest that the protective effect of Ori on ALI is partly mediated by affecting the oxylipin pathway.

Abstract
D-galactosamine (Ga1N), a well-known hepatotoxic agent, induces liver injury resembling human viral hepatitis usually followed by the regeneration processes. Hepatocyte growth factor (HGF) is a cytoprotective factor involved in regeneration of the injured liver. However, the effects of exogenous HGF remain poorly understood because of its rapid clearance by the liver. This study was undertaken to find out whether HGF and fish oil facilitated the reversal of GalN-induced toxicity in primary hepatocyte cultures of albino mice. Primary hepatocytes cultures were established from mice liver tissue. The study involved the effect of GalN on hepatocytes and also determination of the protective role of fish oil on hepatocyte cultures. Cell proliferation tests and liver function tests were done to determine the degree of GalN effect on cultured hepatocytes. Biochemical parameters of cultured cells were also performed to check the recovery effect of fish oil on GalN-induced hepatotoxicity. The combination of Ga1N and HGF triggered cell proliferation in primary hepatocyte cultures specifying activation of regeneration through HGF. However, hepatocyte function tests revealed that although the regeneration process was initiated, its function was slightly altered by Ga1N. Therefore, to control its effect at a functional level, we tested fish oil doses and indicated its influence. This work can be a useful tool for studying hepatotoxic-induced cell regeneration in vitro; moreover, the data indicates that HGF and fish oil has hepatoprotective activity against Ga1N and may aid as a suitable adjuvant in clinical conditions associated with liver damage.

Abstract
This study aimed to determine the anti-inflammatory and hepatoprotective effects of Lysimachiae Herba ethanolic extract (LHE) in lipopolysaccharide (LPS)-stimulated macrophages and in a LPS/D-galactosamine (GalN)-induced acute hepatitis mouse model. Then, the production of inflammatory mediators and the activation of related pathways in macrophages were explored. Finally, we assessed the serum aminotransferase levels and the expression of inflammatory/antioxidant molecules in liver tissues in mice. Results revealed that LHE treatment significantly inhibited the production of inflammatory mediators in LPS-stimulated RAW 264.7 macrophages. Molecular data showed that LHE remarkably increased the activities of the antioxidant pathway and inhibited the phosphorylation of mitogen-activated protein kinase as well as the transcriptional activity of nuclear factor-κB induced by LPS. Furthermore, it prevented acute liver damage caused by LPS/D-GalN-induced hepatitis by inhibiting aminotransferase levels and histopathological changes in mice. Moreover, treatment with LHE significantly inhibited the activation of inflammatory pathways and increased the expression of antioxidant molecules including heme oxygenase-1/Nuclear factor erythroid 2-related factor 2. In conclusion, LHE has potent anti-inflammatory and hepatoprotective effects in LPS-stimulated macrophages and the LPS/D-GalN-induced acute hepatitis mouse model. Thus, it can be a treatment option for inflammation, hepatitis, and liver injury.

Abstract
Forsythia Fruit (FF), the fruit of Forsythia suspensa, has been used since ancient times as an herbal medication in East Asia to treat inflammation, gonorrhea, and pharyngitis. However, the efficacy of FF against liver damage due to inflammation has not been studied. Here, we explored the protective effects of FF in a mouse hepatitis model induced by lipopolysaccharide (LPS)/D-galactosamine (GalN) treatment. We measured inflammatory cytokine and aminotransferase levels in mouse blood and analyzed the effects of FF on inflammatory gene and protein expression levels in liver tissue. Our results show that FF treatment effectively lowers inflammatory cytokine and serum aminotransferase levels in mice and inhibits the expression of hepatic cytokine mRNA and inflammatory proteins. Furthermore, treatment with FF activated the antioxidant pathway HO-1/Nrf-2 and suppressed severe histological alteration in the livers of LPS/D-GalN-treated mice. Further investigation of the effects of FF on inflammatory reactions in LPS-stimulated macrophages showed that pretreatment with FF inhibits inflammatory mediator secretion and activation of inflammatory mechanisms both in a mouse macrophage RAW 264.7 cells and in primary peritoneal macrophages. These results show that FF has potential worth as a candidate for the treatment of fulminant inflammatory reactions and subsequent liver injury.

Abstract
Protective efficacy of rutin over liver, kidney, and brain dysfunctions was evaluated in this investigation. Rutin (5, 10, and 20 mg/kg) was administered continuously for 6 days followed by single dose of D-galactosamine (300 mg/kg I.P.) and lipopolysaccharide (50 µg/kg I.P.) on the 6th day. Hematological, serological, biochemical, and histological aspects were considered for this study. One-way ANOVA (p ≤ .05) followed by Tukey's HSD post hoc test determined the statistical significance. Serum AST, ALT, ALP, urea, uric acid, and creatinine were increased significantly, whereas albumin and glucose were significantly decreased after combined exposure to LPS and D-GalN. Glutathione level and activity of SOD and catalase were decreased, whereas lipid peroxidation, triglycerides, and cholesterol were increased in tissue samples due to LPS- and D-GalN-induced toxicity. Prophylactic treatment of rutin maintained studied variables toward control claiming the protective role of rutin. PRACTICAL APPLICATION: Rutin is plenteous in a variety of commonly ingested foods such as onion, wine, grape, citrus fruits, tea, and buckwheat. Rutin supplement is recommended for the treatment of various diseases such as varicose veins, internal bleeding, or hemorrhoids. Rutin is better than well-known antithrombic agent, Juniferdin, or Bacitracin. In the present study, rutin showed protective effects against LPS- and D-GalN-induced multiorgan dysfunctions due to its anti-inflammatory and antioxidant properties. Therefore, rutin may be developed and practiced as a food supplement to cope with acute organ dysfunctions caused by inflammatory and oxidative damage.

Abstract
BACKGROUND Secondary metabolites of plants, the polyphenols, play a vital role in protection from many health problems in human beings. Structurally favored phytochemicals may be studied to protect multiorgan injury. At pharmacological doses, gallic acid is nontoxic to mammals and is generally absorbed in the intestine. AIMS In this present study, gallic acid was evaluated for its protective efficacy against Lipo Polysaccharide (LPS) and d-Galactosamine (D-GalN) induced multiorgan injury, i.e., liver, kidney and brain. METHODS Three different doses of gallic acid (5, 10 and 20 mg/kg p.o.) were administered to the experimental animals for 6 consecutive days, followed by exposure to LPS (50 μg/kg I.P.) and D-GalN (300 mg/kg I.P.) on the 6th day. RESULTS Exposure to LPS and D-GalN resulted in increased oxidative stress and proinflammatory cytokines. Altered hematology and serology due to LPS and D-GalN were restored towards control by gallic acid. Declined antioxidants such as reduced glutathione, superoxide dismutase and catalase due to injurious effects of LPS and D-GalN were rejuvenated by gallic acid. DISCUSSION Exposure to LPS and D-GalN severely increased lipid peroxidation, CYP2E1 activity and tissue lipids while lowered protein content. Gallic acid restored all these parameters towards control in dose dependent manner and 20 mg/kg dose provided the best protection. Histological study showed improved histoarchitecture of liver, kidney and brain that supported biochemical endpoints. CONCLUSION Gallic acid minimized oxidative stress and provided best protection at 20 mg/kg dose against LPS and D-GalN induced multi organ acute injury.

Abstract
The liver is an important organ for the removal of toxins and utilization of nutrients. The present study then investigated whether a mixture of mulberry water extracts and silk amino acids protected against acute liver damage in rats induced by intraperitoneal injection of D-galactosamine and the action mechanism. D-galactosamine injection is widely used to develop experimental animal models of acute hepatic disease. In the present study, male Sprague-Dawley rats received intraperitoneal injection of D-galactosamine followed by 200 and 600 mg/kg body weight (BW) of mulberry extracts and silk amino acids (1:3, w/w; MS1:3-L and MS1:3-H), the same amounts of MS with different ratios (1:5, w/w; MS1:5-L and MS1:5-H), and 600 mg/kg bw cellulose (control) for 1 week. The normal-control group received an injection of saline instead of D-galactosamine with the same diet as the control group. D-galactosamine injection (control rats) increased serum ALT, AST and γ-GPT levels, indicating the induction of acute liver damage. The control rats also exhibited reduced glycogen depositions, which contributed to increasing fat synthesis from glucose and elevated serum triglyceride levels. Oxidative stress and inflammation in the liver of the control increased in response to the decreasing antioxidant activity and mRNA expression and increasing TNF-α expression, respectively. Both MS1:3 and MS1:5 reduced serum ALT, AST and γ-GPT levels to ameliorate liver damage. MS1:3 reduced oxidative stress by increasing the activity and expression of antioxidant enzymes, whereas MS1:5 decreased the expression TNF-α in the liver. MS1:3 and MS1:5 improved the necrosis of hepatocytes in H&E staining, which was associated with increased glycogen deposition in PAS staining. MS1:5 had better effects on glycogen accumulation. In conclusion, MS1:3 and MS1:5 can be used as therapeutic agents for acute liver damage.

Abstract
Acute liver failure (ALF) is a severe consequence of abrupt hepatocyte injury and has lethal outcomes. Three toll-like receptor agonists, including polyinosinic-polycytidylic acid (poly(I:C)), lipopolysaccharide (LPS), and cytosine-phosphate-guanine (CpG) DNA, cause acute and severe hepatitis, respectively, in D-galactosamine (D-GalN)-sensitized mice. However, the molecular differences among three ALF models (LPS/D-GalN, poly(I:C)/D-GalN, and CpG DNA/D-GalN), are unclear. Here, tandem mass tag based quantitative proteomic analyses of three ALF mouse models are performed. 52 common differentially expressed proteins (DEPs) are identified, in three ALF groups, compared to the control. Gene ontology analyses show that among the common DEPs, ten proteins are involved in immune system process, and 39 proteins in metabolic process. Among 80,195, and 23 specifically-expressed proteins in poly(I:C)/D-GalN, LPS/D-GalN, and CpG DNA/D-GalN groups, LPS/D-GalN-specific proteins are mostly distributed in the endoplasmic reticulum and more enriched in metabolic pathways, whereas poly (I:C)/D-GalN-specific proteins are mainly in the membrane and CpG DNA/D-GalN-specific proteins are related to the ribosome structural composition. In conclusion, the common and specific DEPs in three ALF mouse models at molecular level are identified; and determined a close-to-complete reference map of mouse liver proteins which will be useful for clinical diagnosis and treatment of liver failure in humans.

We examined the influence of liver disease on the absorption from the liver surface of fluorescein isothiocyanate (FITC)-dextran 10 (FD-10, MW: 11000) and several marker compounds with different molecular weights. The purpose of this study was to determine the feasibility of liver surface application of macromolecular compounds in the disease state. We used male Wistar rats treated with carbon tetrachloride (CCl4) or D-galactosamine (GAL). FD-10 and other marker compounds were applied to the liver surface using a cylindrical diffusion cell in liver-intoxicated rats. The blood, bile, urine, and the remaining solution in the diffusion cell were collected for assay. FD-10 was absorbed by first-order kinetics from the liver surface in the liver-intoxicated rat models. The calculated rate constant ka values in the normal, CCl4 and GAL groups were 0.000965, 0.00125 and 0.00104 min-1, respectively. Increased absorption of FITC-dextrans in the liver-intoxicated rats was observed. In both CCl4 and GAL groups, an inverse relationship was observed between the molecular weight and ka from the rat liver surface of the marker compounds. The limits of the molecular weight absorbed from the liver surface were extrapolated to be 71200, 135000, and 105000 in the normal, CCl4, and GAL groups, respectively. In conclusion, increased absorbability from the rat liver surface indicates that liver surface application for liver targeting of macromolecules in the diseased state is indeed feasible. Therefore, our findings can support further research on liver surface application of drugs under liver disease.

Abstract
Aim: To explore the potential therapeutic effect of yttrium oxide nanoparticles (Y2O3 NPs) on fulminant hepatic failure. Materials & methods: RAW264.7 cells and a lipopolysaccharide/D-galactosamine-induced hepatic failure murine model were used to assess the effects of Y2O3 NPs. Results: Y2O3 NPs exhibited anti-inflammatory activity by scavenging cellular reactive oxygen species and dampening reactive oxygen species-mediated NF-κB activation in vitro. A single intraperitoneal administration of Y2O3 NPs (30 mg/kg) enhanced hepatic antioxidant status and reduced oxidative stress and inflammatory response in lipopolysaccharide/galactosamine-induced mice. Y2O3 NPs also attenuated hepatic NF-κB activation, cell apoptosis and liver injury. Conclusion: Y2O3 NP administration could be used as a novel therapeutic strategy for treating fulminant hepatic failure and oxidative stress-related diseases.

Abstract
OBJECTIVE We aim to investigate the protective effects of compound Cotinus coggygria oral liquid on acute liver injury of mice induced by D-galactosamine (GalN). METHODS Acute liver injury mouse model was established by D-GalN. A total of 72 mice were randomly divided into the blank group, model group constructed by D-GalN, Huganning tablet-treated model group (1.0125 g/kg, as the positive control group), and large (30 ml/kg), medium (15 ml/kg) and small (7.5 ml/kg) doses of compound Cotinus coggygria oral liquid-treated model groups. SPSS 17.0 was used for statistical analysis. RESULTS Compared to the blank group, the model group demonstrated alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in mice serum and liver homogenate was significantly increased (P<0.01), alteration of liver tissue structure and obvious hepatic cytolysis necrosis, indicating successfully establishement of acute liver injury model. Compared with the model group, the liver index is significantly decreased in large and medium doses of compound Cotinus coggygria oral liquid treated groups (P<0.05), and the effects of large doses of compound Cotinus coggygria are more significant (P<0.01). Furthermore, different doses of compound Cotinus coggygria oral liquid can significantly reduce the activity of mice serum ALT, AST (P<0.01). Large and medium doses of compound Cotinus coggygria oral liquid significantly reduce the activities of ALT (P<0.01) and AST in liver homogenate (P<0.05), and also improve the structure of liver tissues, decreasing the amount of hepatic necrosis, which is associated with liver cell regeneration. CONCLUSION Compound Cotinus coggygria oral liquid has protective effects on mice acute liver injury induced by D-GalN.

Abstract
Acute hepatic injury caused by inflammatory liver disease is associated with high mortality. This study examined the role of caveolin-1 (Cav-1) in lipopolysaccharide (LPS) and D-galactosamine (GalN)-induced fulminant hepatic injury in wild type and Cav-1-null (Cav-1-/- ) mice. Hepatic Cav-1 expression was induced post-LPS/GalN treatment in wild-type mice. LPS/GalN-treated Cav-1-/- mice showed reduced lethality and markedly attenuated liver damage, neutrophil infiltration and hepatocyte apoptosis as compared to wild-type mice. Cav-1 deletion significantly reduced LPS/GalN-induced caspase-3, caspase-8 and caspase-9 activation and pro-inflammatory cytokine and chemokine expression. Additionally, Cav-1-/- mice showed suppressed expression of Toll-like receptor 4 (TLR4) and CD14 in Kupffer cells and reduced expression of vascular cell adhesion molecule 1 and intercellular adhesion molecule 1 in liver cells. Cav-1 deletion impeded LPS/GalN-induced inducible nitric oxide synthase expression and nitric oxide production and hindered nuclear factor-κB (NF-κB) activation. Taken together, Cav-1 regulated the expression of mediators that govern LPS-induced inflammatory signalling in mouse liver. Thus, deletion of Cav-1 suppressed the inflammatory response mediated by the LPS-CD14-TLR4-NF-κb pathway and alleviated acute liver injury in mice.

Abstract
The phytochemical study on Corydalis tomentella Franch, a traditional Chinese medicinal plant in Tibet, China, led to the isolation of six previously undescribed isoquinolines, including two rarely reported N-benzyl ones, and twenty-one known ones firstly obtained from this plant. Their planar structures were elucidated by 1D, 2D NMR experiments and high resolution mass spectrometry, and the absolute configurations were determined by NOE experiments, electronic circular dichroism, and specific rotation. Seven isoquinolines exhibited stronger hepatoprotective activities than that of positive control in D-galactosamine induced L02 cells damage model, which could be served as the leading compounds for further investigations. The primary structure-activity relationship was also summarized accordingly.

Abstract
Acute liver failure is a drastic, unpredictable clinical syndrome with high mortality. Various preventive and adjuvant therapies based on modulating the gut flora have been proposed for hepatic injury. We aimed to explore the preventive and therapeutic effects of Bifidobacterium adolescentis CGMCC15058 on rat liver failure, as well as the potential microecological and immunological mechanisms of those effects. B. adolescentis CGMCC15058 (3 × 109 CFU), isolated from healthy human stool, was gavaged to Sprague-Dawley rats for 14 days. Acute liver injury was induced on the 15th day by intraperitoneal injection of D-galactosamine. After 24 h, liver and terminal ileum histology, liver function, plasma cytokines, bacterial translocation and gut microbiota composition were assessed. We found that pretreatment with B. adolescentis significantly relieved elevated serum levels of alanine aminotransferase (ALT), total bile acid and lipopolysaccharide-binding protein and enhanced the expression of mucin 4 and the tight junction protein zonula occludens-1. B. adolescentis exhibited anti-inflammatory properties as indicated by decreased levels of mTOR and the inflammatory cytokines TNF-α and IL-6, as well as elevated levels of the anti-inflammatory cytokine interleukins-10 in the liver. Similar anti-inflammatory signs were also found in plasma. B. adolescentis significantly altered the microbial community, depleting the common pathogenic taxon Proteus and markedly enriching the taxa Coriobacteriaceae, Bacteroidales and Allobaculum, which are involved in regulating the metabolism of lipids and aromatic amino acids. Our findings not only suggest B. adolescentis acts as a prospective probiotic against liver failure but also provide new insights into the prevention and treatment of liver disease.

Abstract
The purpose of this study was to investigate the protective effect of catalpol on Lipopolysaccharide (LPS)/D-galactosamine (D-gal)-induced acute liver injury in mice. The mouse model was established by injection of LPS and D-gal. Catalpol (2.5, 5, 10 mg/kg) were pretreated intraperitoneally 1 h before LPS and D-gal. The survival rate, AST, ALT, MDA, MPO activity, hepatic tissue histology, TNF-α level, and NF-κB activation were assayed. The results revealed that catalpol dose-dependently elevated the survival rate. Furthermore, catalpol reduced the activities of AST, ALT, MDA, and MPO. The production of TNF-α was also inhibited by treatment of catalpol. In addition, catalpol inhibited LPS/D-gal-induced NF-κB activation. The expression of Nrf2 and HO-1 were up-regulated by treatment of catalpol. These results indicated that pretreatment with catalpol could attenuate LPS/D-gal-induced acute liver injury in mice and the underlying mechanism may due to the inhibition of NF-κB signaling pathway and the activation of Nrf2 signaling pathway.

Abstract
AIM To establish a simplified, reproducible D-galactosamine-induced cynomolgus monkey model of acute liver failure having an appropriate treatment window.
METHODS Sixteen cynomolgus monkeys were randomly divided into four groups (A, B, C and D) after intracranial pressure (ICP) sensor implantation. D-galactosamine at 0.3, 0.25, 0.20 + 0.05 (24 h interval), and 0.20 g/kg body weight, respectively, was injected via the small saphenous vein. Vital signs, ICP, biochemical indices, and inflammatory factors were recorded at 0, 12, 24, 36, 48, 72, 96, and 120 h after D-galactosamine administration. Progression of clinical manifestations, survival times, and results of H&E staining, TUNEL, and Masson staining were recorded.
RESULTS Cynomolgus monkeys developed different degrees of debilitation, loss of appetite, and jaundice after D-galactosamine administration. Survival times of groups A, B, and C were 56 ± 8.7 h, 95 ± 5.5 h, and 99 ± 2.2 h, respectively, and in group D all monkeys survived the 144-h observation period except for one, which died at 136 h. Blood levels of ALT, AST, CK, LDH, TBiL, Cr, BUN, and ammonia, prothrombin time, ICP, endotoxin, and inflammatory markers [(tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6)] significantly increased compared with baseline values in different groups (P < 0.05). Pathological results showed obvious liver cell necrosis that was positively correlated with the dose of D-galactosamine.
CONCLUSION We successfully established a simplified, reproducible D-galactosamine-induced cynomolgus monkey model of acute liver failure, and the single or divided dosage of 0.25 g/kg is optimal for creating this model.

Abstract
Nymphaea candida was used to treat hepatitis in Ugyhur medicine, and nicotiflorin (kaempferol 3-O-β-rutinoside) is the main characteristic component in this plant. In this study, The the hepatoprotective activities of nicotiflorin from N. candida were investigated by Concanavalin A (Con A, 20 mg/kg bw)- and d-Galactosamine (d-GalN, 800 mg/kg bw)-induced acute liver injury in mice. Pretreatment with nicotiflorin (25, 50, 100 mg/kg bw/day, p.o.) for ten days significantly reduced the impact of Con A toxicity (20 mg/kg bw) on the serum markers of liver injury, aspartate aminotransferase (AST), and alanine aminotransferase (ALT). The hepatic anti-oxidant parameters (malondialdehyde, MDA; superoxide dismutase, SOD; glutathione, GSH; and nitric oxide, NO) in mice with nicotiflorin treatment were significantly antagonized for the pro-oxidant effects of Con A. Moreover, pretreatment with nicotiflorin (100 mg/kg bw) significantly decreased Con A-induced elevation in the serum levels of pro-inflammatory cytokines interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) (p < 0.05). A protective effect was reconfirmed against d-GalN-induced chemical liver injury, elevated serum enzymatic and cytokines levels were significantly decreased by nicotiflorin, and liver homogenate antioxidant indicators were significantly restored toward normal levels. Both histopathological studies also supported the protective effects of nicotiflorin. Therefore, the presented results suggest that nicotiflorin is the potent hepatoprotective agent that could protect the liver against acute immunological and chemical injury; this ability might be attributed to its antioxidant and immunoregulation potential.

Abstract
Background: Bruguiera gymnorrhiza L. (family Rhizophoraceae) is a true mangrove habitat in Indian Sunderban and traditionally uses for liver disorders. Objectives: The aim was to evaluate antioxidant and hepatoprotective actions of leave extract of B. gymnorrhiza L. Materials and Methods: Hydro-methanolic extract of mangrove leaves (BR) was standardized using spectrophotometric and high-performance thin layer chromatography methods. Radical scavenging activities were assessed in different in vitro methods, like 1,1-diphenyl-2-picrylhydrazyl, 2,2’-azino-bis-3-ethyl benzthiazoline-6-sulphonic acid +, superoxides, nitric oxides and hydroxyl radicals. Hepatoprotective efficacy of BR (125 mg/kg and 250 mg/kg, p.o) was measured in D-galactosamine (GalN) induced (200 mg/kg, i.p) hepatitis in Wistar rats. Silymarin (25 mg/kg, p.o) was used as known hepatoprotective agent. Results: Polyphenols such as gallic acid, quercetin, and coumarin obtained from BR exhibited powerful antioxidant properties. Moreover, it produced dose-dependent protection against GalN induced hepatitis in rats. It significantly reduced GalN induced elevation of enzymes (alanine transaminase, aspartate aminotransferase, and alkaline phosphatase) in serum and resist oxidative stress marked by lipid peroxides, glutathione, and catalase in hepatic parenchyma. Conclusions: Polyphenols rich B. gymnorrhiza L. leaves ameliorate hepatic tissue injury through its antioxidant effects.

Abstract
BACKGROUND Sphingosine kinase 1 (SphK1)/sphingosine-1-phosphate (S1P)/sphingosine-1-phosphate receptors (S1PRs) signaling plays a key role in inflammatory responses. Lei et al. showed that SphK1 inhibition presented a hepatoprotective effect on acute liver damage via decreasing hepatic high-mobility group box 1 (HMGB1) cytoplasmic translocation. OBJECTIVE We aim to determine whether SphK1 or S1PRs inhibition improves lipopolysaccharide (LPS)/D-galactosamine (GalN)-induced acute liver failure by inhibiting the mitogen-activated protein kinases (MAPKs) pathway. METHODS A mouse model of acute liver failure was induced by LPS/GalN. Male C57BL/6J mice (6-8 weeks) were randomly distributed into five groups: control group, LPS/GalN group, SphK1 inhibition group (LPS/GalN+SKI-5c), S1PR1 inhibition group (LPS/GalN+W146), and S1PR3 inhibition group (LPS/GalN+CAY10444). RESULTS We confirmed the findings of Lei et al. that hepatic SphK1 expression was upregulated; serum transaminase activity (AST, ALT), as well as serum TNF-α and IL-6, were decreased by SphK1 inhibition. We further showed that the expression of S1PR1 and S1PR3 was augmented in response to LPS/GalN. SphK1 inhibition improves hepatic hemorrhage, and the activities of hepatic caspase-3 and myeloperoxidase (MPO). Furthermore, the activation of the MAPKs family (JNK, ERK and p38) was suppressed by SphK1 inhibition. However, S1PR1 or S1PR3 inhibition did not protect the mouse against liver damage, though S1PR1 or S1PR3 inhibition reduced serum TNF-α and IL-6, and partially attenuated the phosphorylation of the MAPKs signaling. CONCLUSIONS SphK1 inhibition improves LPS/GalN-induced liver injury by inhibiting activation of MAPKs signaling.

Abstract
Fulminant hepatic failure (FHF) is a lethal clinical syndrome characterized by the activation of macrophages and the increased production of inflammatory mediators. The purpose of this study was to investigate the effects of neohesperidin dihydrochalcone (NHDC), a widely-used low caloric artificial sweetener against FHF. An FHF experimental model was established in mice by intraperitoneal injection of D-galactosamine (d-GalN) (400mg/kg)/lipopolysaccharides (LPS) (10 μg/kg). Mice were orally administered NHDC for 6 continuous days and at 1h before d-GalN/LPS administration. RAW264.7 macrophages were used as an in vitro model. Cells were pre-treated with NHDC for 1h before stimulation with LPS (10 μg/ml) for 6h. d-GalN/LPS markedly increased the serum transaminase activities and levels of oxidative and inflammatory markers, which were significantly attenuated by NHDC. Mechanistic analysis indicated that NHDC inhibited LPS-induced myeloid differentiation factor 88 (MyD88) and TIR-containing adapter molecule (TRIF)-dependent signaling. Transient transfection of TLR4 or MyD88 siRNA inhibited the downstream inflammatory signaling. This effect could also be achieved by the pretreatment with NHDC. The fluorescence microscopy and flow cytometry results suggested that NHDC potently inhibited the binding of LPS to TLR4 in RAW264.7 macrophages. In addition, the inhibitory effect of NHDC on LPS-induced translocation of TLR4 into lipid raft domains played an important role in the amelioration of production of downstream pro-inflammatory molecules. Furthermore, the activation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) by NHDC inhibited TLR4 signaling. In conclusion, our results suggest that NHDC attenuates d-GalN/LPS-induced FHF by inhibiting the TLR4-mediated inflammatory pathway, demonstrating a new application of NHDC as a hepatoprotective agent.

Abstract
Acute liver failure can be the consequence of various etiologies, with most cases arising from drug-induced hepatotoxicity in Western countries. Despite advances in this field, the management of acute liver failure continues to be one of the most challenging problems in clinical medicine. The availability of adequate experimental models is of crucial importance to provide a better understanding of this condition and to allow identification of novel drug targets, testing the efficacy of new therapeutic interventions and acting as models for assessing mechanisms of toxicity. Experimental models of hepatotoxicity related to acute liver failure rely on surgical procedures, chemical exposure or viral infection. Each of these models has a number of strengths and weaknesses. This paper specifically reviews commonly used chemical in vivo and in vitro models of hepatotoxicity associated with acute liver failure.

Abstract
AIM: To develop a practical and reproducible rat model of hepatorenal syndrome for further study of the pathophysiology of human hepatorenal syndrome.
METHODS: Sprague-Dawley rats were intravenously injected with D-galactosamine and lipopolysaccharide (LPS) via the tail vein to induce fulminant hepatic failure to develop a model of hepatorenal syndrome. Liver and kidney function tests and plasma cytokine levels were measured after D-galactosamine/LPS administration, and hepatic and renal pathology was studied. Glomerular filtration rate was detected in conscious rats using micro-osmotic pump technology with fluorescein isothiocyanate-labelled inulin as a surrogate marker.
RESULTS: Serum levels of biochemical indicators including liver and kidney function indexes and cytokines all significantly changed, especially at 12 h after D-galactosamine/LPS administration [alanine aminotransferase, 3389.5 ± 499.5 IU/L; blood urea nitrogen, 13.9 ± 1.3 mmol/L; Cr, 78.1 ± 2.9 μmol/L; K+, 6.1 ± 0.5 mmol/L; Na+, 130.9 ± 1.9 mmol/L; Cl-, 90.2 ± 1.9 mmol/L; tumor necrosis factor-α, 1699.6 ± 599.1 pg/mL; endothelin-1, 95.9 ± 25.9 pg/mL; P < 0.05 compared with normal saline control group]. Hepatocyte necrosis was aggravated gradually, which was most significant at 12 h after treatment with D-galactosamine/LPS, and was characterized by massive hepatocyte necrosis, while the structures of glomeruli, proximal and distal tubules were normal. Glomerular filtration rate was significantly decreased to 30%-35% of the control group at 12 h after D-galactosamine/LPS administration [Glomerular filtration rate (GFR)1, 0.79 ± 0.11 mL/min; GFR2, 3.58 ± 0.49 mL/min·kgBW-1; GFR3, 0.39 ± 0.99 mL/min·gKW-1]. The decreasing timing of GFR was consistent with that of the presence of hepatocyte necrosis and liver and kidney dysfunction.
CONCLUSION: The joint use of D-galactosamine and LPS can induce liver and kidney dysfunction and decline of glomerular filtration rate in rats which is a successful rat model of hepatorenal syndrome.

Abstract
BACKGROUND & AIMS The neuroprotective effect of the spheroid reservoir bioartificial liver (SRBAL) was evaluated in a porcine model of drug-overdose acute liver failure (ALF). METHODS Healthy pigs were randomized into three groups (standard therapy (ST) alone, ST+No-cell device, ST+SRBAL device) before placement of an implantable intracranial pressure (ICP) monitor and a tunneled central venous catheter. One week later, pigs received bolus infusion of the hepatotoxin D-galactosamine and were followed for up to 90h. RESULTS At 48h, all animals had developed encephalopathy and biochemical changes confirming ALF; extracorporeal treatment was initiated and pigs were observed up to 90h after drug infusion. Pigs treated with the SRBAL, loaded with porcine hepatocyte spheroids, had improved survival (83%, n=6) compared to ST alone (0%, n=6, p=0.003) and No-cell device therapy (17%, n=6, p=0.02). Ammonia detoxification, peak levels of serum ammonia and peak ICP, and pig survival were influenced by hepatocyte cell dose, membrane pore size and duration of SRBAL treatment. Hepatocyte spheroids remained highly functional with no decline in mean oxygen consumption from initiation to completion of treatment. CONCLUSIONS The SRBAL improved survival in an allogeneic model of drug-overdose ALF. Survival correlated with ammonia detoxification and ICP lowering indicating that hepatocyte spheroids prevented the cerebral manifestations of ALF (brain swelling, herniation, death). Further investigation of SRBAL therapy in a clinical setting is warranted.

Abstract
The oral pre-administration of proline, one on the non-essential amino acids, has been shown to effectively protect the liver from D-galactosamine (GalN)-induced liver injury and dramatically improve the survival rate. In the previous study, we reported that protective effect of proline involves the early activation of IL-6/STAT-3 pathway, an anti-inflammatory and regenerative signaling in the liver. Reactive oxygen species (ROS) are mediator of cellular injury and play an important role in hepatic damage during GalN-induced hepatitis. The aim of this study is to investigate the effect of proline on ROS-eliminating system. The activities of major ROS-detoxifying enzymes, i.e., glutathione peroxidase (GP), glutathione reductase (GR), catalase, and the level of glutathione in the liver were determined. Catalase activity was significantly upregulated in proline group from 0 to 3 h after GalN-injection, although GP and GR were downregulated during this period, compared with control group. From 6 to 12 h, the level of reduced glutathione (GSH) was significantly higher and the ratio of GSH/oxidized glutathione (GSSG) tended to be higher in proline group. Consistently with this, at 6 h, the GR activity in the proline group was significantly higher, followed with the higher tendency of GP activity at 12 h. Catalase activity was also significantly higher at 12 h. Taken together, catalase was activated at the beginning, followed with the significant activation of glutathione redox system around 6 to 12 h in proline group. These results suggest that the elimination of ROS in the liver was accelerated in proline group compared with control group at the very early stage of GalN-induced hepatitis.

Abstract
Acute liver failure (ALF) remains an extremely poor prognosis and high mortality; with no effective treatments. The endotoxin tolerance (ET) phenotype has been reported to exhibit protective activities in several sepsis models. We now investigated the effects and underlying intraperitoneal injection of the same volume of pyrogen-free 0.9% sodium chloride instead of LPS for five consecutive days before D-GalN/LPS injection in rats. The serum levels of TNF-α, IL-6, ALT, AST and TBiL from ET + ALF group and ALF group were measured at different time points. Our results showed that ET + ALF group markedly reduced the serum levels of TNF-α, IL-6, ALT, AST and TBiL and histological features in the ET + ALF group were improved significantly. Furthermore, LPS pre-treatment inhibited D-GalN/LPS-induced NF-κB activation, Bax activation, signal transducer and activator of transcription-1 (STAT1) and signal transducer and activator of transcription-3 (STAT3) activities. LPS pre-treatment also significantly enhance the expression of suppressors of cytokine signaling 1 (SOCS1) and suppressors of cytokine signaling 3 (SOCS3). Our experimental data indicated that ET might alleviate D-GalN/LPS-induced ALF by inhibiting the inflammatory response, inactivation of STAT1 and STAT3 and up-regulation of SOCS1 and SOCS3.

Abstract
Literature data support that green tea and its major component epigallocatechin gallate (EGCG) have powerful antioxidant effects. Contrary, hepatotoxicity can be induced by high-dose EGCG. The timing of exposure to green tea in relation to administration of hepatotoxic agent plays an import role too. The aim of our work was a verification of antioxidative effect of EGCG on D-galactosamine-induced injury in primary culture of rat hepatocytes. Hepatocytes were incubated with EGCG at concentrations of 1.25-10 μM and toxic D-galactosamine (GalN) for 24 hrs. Alternatively, hepatocytes were pretreated with EGCG for 24 hrs, and then incubated with EGCG and GalN for further 24 hrs. Cytotoxicity was analysed by lactate dehydrogenase activity, functional capacity by albumin production. Oxidative stress was evaluated from a production of malondialdehyde and glutathione content in the cells. EGCG protected hepatocytes against GalN-induced cytotoxicity but preventive treatment of intact hepatocytes with EGCG was required to diminish the development of hepatocyte injury. Oxidative stress induced in our study seems to overcome the ability of hepatocytes to improve GSH depletion and albumin production. Prolongation of the pretreatment with EGCG could be a promising strategy leading to amelioration of its hepatoprotective effect.

Abstract
OBJECTIVE This study aimed to investigate the protective effects of echinacoside, one of the phenylethanoids isolated from the stems of Cistanche salsa, a Chinese herbal medicine, on D-galactosamine (GalN) and lipopolysaccharide (LPS)-induced acute liver injury in mice. METHODS We administered GalN (650 mg/kg) together with LPS (30 μg/kg) to mice by intraperitoneal injection to induce acute liver damage. Echinacoside (60 mg/kg) was given intraperitoneally to mice at 1 h prior to GalN/LPS exposure. Mice were sacrificed at different time points following GalN/LPS treatment, and the liver and blood samples were collected for future analysis. RESULTS It showed that GalN/LPS treatment produced severe hepatic injury, evidenced by significantly elevated plasma alanine aminotransferase (ALT) levels and abnormal histological changes such as hepatocyte necrosis or apoptosis, hemorrhage, fatty degeneration, and neutrophil infiltration. Notably, pretreatment with echinacoside remarkably improved the survival rate of GalN/LPS-treated mice and attenuated acute hepatotoxicity, as demonstrated by decreased ALT levels and improved histological signs. Echinacoside shows both anti-apoptotic and anti-inflammatory properties, characterized by a substantial inhibition of hepatocyte apoptosis and a significant reduction in the inflammatory markers, including myeloperoxidase, extracellular nucleosomes, high-mobility group box 1, and inflammatory cytokines in the plasma of mice, which may be important mechanisms related to its protective effect. CONCLUSION Our results suggest that echinacoside can provide a pronounced protection against GalN/LPS-induced acute liver injury in mice, which may complement the available strategies for management of acute liver damage in clinical settings.

Abstract
In this study, we investigated the hepatoprotective effects of aged black garlic (ABG) in rodent models of liver injury. ABG inhibited carbon tetrachloride-induced elevation of aspartate transaminase (AST) and alanine transaminase (ALT), which are markers of hepatocellular damage, in SD rats. D-galactosamineinduced hepatocellular damage was also suppressed by ABG treatment. However, ABG does not affect the elevation of alkaline phosphatase (ALP), a marker of hepatobilliary damage, in rats treated with carbon tetrachloride or D-galactosamine. We also examined the effect of ABG on high-fat diet (HFD)-induced fatty liver and subsequent liver damage. ABG had no significant effect on body weight increase and plasma lipid profile in HFD-fed mice. However, HFD-induced increase in AST and ALT, but not ALP, was significantly suppressed by ABG treatment. These results demonstrate that ABG has hepatoprotective effects and suggest that ABG supplementation might be a good adjuvant therapy for the management of liver injury.

Abstract
BACKGROUND & AIMS Metabolomics is comprehensive analysis of low-molecular-weight endogenous metabolites in a biological sample. It could enable mapping of perturbations of early biochemical changes in diseases and hence provide an opportunity to develop predictive biomarkers that could provide valuable insights into the mechanisms of diseases. The aim of this study was to elucidate the changes in endogenous metabolites and to phenotype the metabolic profiling of d-galactosamine (GalN)-inducing acute hepatitis in rats by UPLC-ESI MS. METHODS The systemic biochemical actions of GalN administration (ip, 400 mg/kg) have been investigated in male wistar rats using conventional clinical chemistry, liver histopathology and metabolomic analysis of UPLC- ESI MS of urine. The urine was collected predose (-24 to 0 h) and 0-24, 24-48, 48-72, 72-96 h post-dose. Mass spectrometry of the urine was analysed visually and via conjunction with multivariate data analysis. RESULTS Results demonstrated that there was a time-dependent biochemical effect of GalN dosed on the levels of a range of low-molecular-weight metabolites in urine, which was correlated with developing phase of the GalN-inducing acute hepatitis. Urinary excretion of beta-hydroxybutanoic acid and citric acid was decreased following GalN dosing, whereas that of glycocholic acid, indole-3-acetic acid, sphinganine, n-acetyl-l-phenylalanine, cholic acid and creatinine excretion was increased, which suggests that several key metabolic pathways such as energy metabolism, lipid metabolism and amino acid metabolism were perturbed by GalN. CONCLUSION This metabolomic investigation demonstrates that this robust non-invasive tool offers insight into the metabolic states of diseases.

Abstract
Mechanisms underlying the mitochondrial protection of Limonium sinense extracts (LSE) was studied in lipopolysaccharide and D-galactosamine (LPS/D-GalN) intoxicated mice. It was found that increased activities of serum aspartate aminotransferase and alanine aminotransferase induced by LPS/D-GalN were significantly inhibited by pretreatment with LSE. The obvious disruption of membrane potential, intramitochondrial Ca 2+ overload and suppression in mitochondrial Ca 2+ -ATPase activity induced by LPS/D-GalN were significantly blocked by pretreatment with LSE. It was concluded that mechanisms underlying protection of LSE against liver mitochondria damage might be related to the preservation on mitochondrial Ca 2+ homeostasis through the preservation on mitochondrial Ca 2+ -ATPase activity.

Abstract
This study evaluated the potential beneficial effect of Moutan Cortex Radicis (MCR) in a murine model of carbon tetrachloride (CCl(4))-, D-galactosamine (GalN)- and α-naphthylisothiocyanate (ANIT)-induced liver injury. Acute hepatotoxicity was induced by intraperitoneal injection of CCl(4) (10 µL/kg), GalN (700 mg/kg), and ANIT (40 mg/kg). Animals received MCR (30, 100, and 300 mg/kg ) orally at 48, 24, and 2 h before and 6 h after administration of CCl(4), GalN, and ANIT. Serum activities of aminotransferase were significantly higher at 24 h after CCl(4) or GalN treatment. These changes were attenuated by MCR. Histopathological analysis revealed multiple and extensive areas of portal inflammation, hepatocellular necrosis, and an increase in inflammatory cell infiltration. These changes were inhibited by MCR. Serum total bilirubin concentration increased and bile flow decreased significantly 48 h after ANIT treatment, which was attenuated by MCR. Our results suggest that MCR has a protective effect on acute liver injury.

Abstract
AIM: To establish a non-human primate model of acute liver failure (ALF).
METHODS: Fifteen healthy cynomolgus monkeys (Macaca fascicularis) were randomly divided into three groups, which were administered with D-galactosamine via the jugular vein at doses of 0.45 (high-dose group), 0.3 (medium-dose group) and 0.15 g/kg (low-dose group), respectively, to induce ALF. At 0, 12, 24, 36, 48, 60, 72 and 96 h after administration, clinical and intracranial pressure (ICP) data were recorded, and blood samples were collected for measurement of alanine aminotransferase (ALT), prothrombin time (PT), total bilirubin (TBIL), and ammonia (NH3). Animal survival time was recorded to compare the survival rates among the three groups. Postmortem examination was performed in dead cynomolgus monkeys.
RESULTS: All animals were dead in the high- and medium-dose groups, and the mean survival time was 56.1 h ± 8.1 h and 109.8 h ± 11.2 h, respectively. Only one animal died at 98 h after treatment in the low-dose group. In the high- and medium-dose groups, serum levels of ALT, PT, TBIL and NH3, and ICP were significantly higher at all time points than at baseline (0 h) (all P < 0.05). All these parameters were normal at 60 h in the low-dose group. Inflammatory cell infiltration and hepatic cell necrosis were observed in dead cynomolgus monkeys.
CONCLUSION: A cynomolgus monkey model of AHF has been successfully established and can be used for future ALF research.

Abstract
To investigate Lecithin for its hepatoprotective activity against D-galactosamine (D-GalN) induced toxicity in freshly isolated rat hepatocytes and animal models. Freshly isolated rat hepatocytes were exposed to Dgalactosamine (30 mM) along with/without lecithin (100 μg/ml) and the levels of selected liver enzymes were measured. Thirty six Wistar strain albino rats were used for the in vivo investigations. Lecithin 50 and 100 mg/kg.b.wt were administered for one week by oral route. Liver damage was induced by intra peritoneal administration of 400 mg/kg b.wt D-galactosamine. The antihepatotoxic effect of lecithin was observed in freshly isolated rat hepatocytes at concentration 100 μg/ml and was found to be similar to that of the standard silymarin used. Its in vivo hepatoprotective effect at 100 mg/kg b.wt was comparable with that of the standard silymarin at 100 mg/kg body weight. Lecithin was able to normalise the biochemical levels which were altered due to D-galactosamine intoxication in freshly isolated rat hepatocytes and also in animal models.

Abstract
AIM: To investigate the changes of heme oxygenase-1 (HO-1) expression and carbon monoxide (CO) production in acute liver injury induced by D-galactosamine (GalN) and Lipopolysaccharide (LPS), and explore the role of HO-1/CO system in the pathogenesis of liver injury.
METHODS: GalN (700 mg/kg body weight) and LPS (50 μg/kg body weight) were used to establish the models of acute liver injury in male rats by intraperitoneal injection. Liver injury was assessed biochemically and histologically. HO-1 activity in liver homogenate was examined at different time points following GalN/LPS treatment and the expression of HO-1 protein was determined by Western blot. The activity of super oxide dismutase (SOD) and the content of malondialdehyde (MDA) in liver tissues were also examined at the same time.
RESULTS: Administration of GalN/LPS caused severe hepatic damage, characterized by significant elevation of serum alanine aminotransferase (ALT: 10872.5 ± 708.5 nkat/L vs 1043.5 ± 247.4 nkat/L, P < 0.01), aspartate aminotransferase (AST: 9246.8 ± 814.7 nkat/L vs 1278.6 ± 273.8 nkat/L, P < 0.01) levels and hepatic MDA content (5.06 ± 1.21 μmol/g vs 2.03 ± 0.59 μmol/g, P < 0.01) as well as a remarkable reduction of liver SOD activity (813.7 ± 168.3 nkat/mg vs 1248.2 ± 84.9 nkat/mg, P < 0.01) at 24 hours as compared with those in the control group. HO-1 activity was elevated significantly after modeling, showing a time-dependent manner from 6 to 24 hours (4.02 ± 0.74, 5.97 ± 1.51, 6.13 ± 1.18 μmol/g vs 2.86 ± 0.41 μmol/g), while expression of HO-1 protein was increased remarkably from 6 to 24 hours (24 h: 1.87 ± 0.39 vs 0.37 ± 0.09, P < 0.01), which was demonstrated by Western blot analysis. Endogenous CO concentration in the liver of control rats remained very low but was elevated significantly after GalN/LPS treatment (6, 12, 24 h: 0.373 ± 0.112, 0.474 ± 0.152, 0.513 ± 0.193 μmol/g vs 0.172 ± 0.041 μmol/g, P < 0.01), which was in accordance with the changes of HO-1.
CONCLUSION: HO-1 activity and protein as well as CO production are increased significantly in rats with acute liver injury induced by GalN/LPS, suggesting that HO-1/CO system plays an important role in the pathogenesis of acute hepatic damage.

Abstract
AIM: To investigate the pathogenic effect of SEB and D-GalN on liver and the protection of cyclosporin A, the relationship between hepatic apoptosis and necrosis and the possible mechanism of acute hepatic necrosis.
METHODS: After staphylococcal enterotoxin B (SEB) mixed with D-galactosamine (D-GalN) were injected intraperitoneally into Balb/c mice and those previously treated with cyclosporin A, blood samples were collected and livers were isolated at 2, 6, 12, 24h. Patterns of hepatocellular death were studied morphologically and biochemically, circulating cytokines (TNF-α, IFN-γ) and mice mortality within 24h was assessed.
RESULTS: The SEB could induce the typical apoptotic changes of hepatocytes, the D-GalN could induce hepatocytes apoptosis and degeneration at the same time, and the mice having received the SEB + D-GalN injections developed apoptosis at 2 and 6h, but after 12h hepatocytes were characterized by severe injury, whereas all the examinations in the cyclosporin A treated mice were normal.
CONCLUSION: Hepatic cell apoptosis might be related to necrosis, and massive hepatocyte apoptosis is likely the initiating step of acute hepatic necrosis in mice. The effects induced by SEB and D-GalN on hepatocytes might be mediated by T cells, and could be prevented by cyclosporin A.
