Kondeva-Burdina M, Shkondrov A, Popov G, Manov V, Krasteva I. In Vitro/In Vivo Hepatoprotective and Antioxidant Effects of Defatted Extract and a Phenolic Fraction Obtained from Phlomis Tuberosa. Int J Mol Sci 2023; 24:10631. [PMID: 37445808 DOI: 10.3390/ijms241310631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 06/21/2023] [Accepted: 06/23/2023] [Indexed: 07/15/2023] Open
Abstract
An in vitro/in vivo hepatotoxicity and hepatoprotection evaluation of a defatted extract and a phenolic fraction from Phlomis tuberosa, administered alone and in a carbon tetrachloride (CCl4)-induced metabolic bioactivation model, was performed. The extract and the phenolic fraction were analysed by high performance liquid chromatography (HPLC) to determine the total flavonoid content, to identify flavonoids and to quantify verbascoside. In addition, total polyphenolics in the samples were expressed as gallic acid equivalents. Applied alone, the extract and the fraction (5, 10 and 50 µg/mL) did not show a statistically significant hepatotoxic effect on isolated rat hepatocytes in vitro. In a CCl4-induced hepatotoxicity model, the samples exhibited a concentration-dependent, statistically significant hepatoprotective effect, which was most pronounced at 50 µg/mL for both. The phenolic fraction exhibited a more pronounced hepatoprotective effect compared to the extract. Data from the in vitro study on the effects of the extract were also confirmed in the in vivo experiment conducted in a CCl4-induced hepatotoxicity model in rats. A histopathological study showed that the animals treated with CCl4 and the extract had an unaltered histoarchitecture of the liver. The effects of the extract were the same as those of silymarin.

Abstract
The prevalence of chronic diseases has increased significantly with the rising trend of sedentary lifestyles, reduced physical activity, and dietary modifications in recent decades. Inflammation and oxidative stress play a key role in the pathophysiology of several chronic diseases, such as type II diabetes, cardiovascular diseases, and hepatic conditions. Therefore, reducing inflammation and oxidative stress may be beneficial in the prevention and treatment of various chronic disorders. Since chronic diseases are not completely curable, various methods have been proposed for their control. Complementary therapies and the use of natural antioxidant and antiinflammatory compounds are among these novel approaches. Pycnogenol (PYC) is a natural compound that could control inflammation and oxidative stress. Furthermore, some previous studies have shown that PYC could effectively reduce inflammation through signaling the downstream of insulin receptors, inhibiting the phosphorylation of the serine residues of insulin receptor substrate-1, reducing pro-inflammatory cytokines and oxidative stress indices through the stimulation of antioxidant pathways, increasing free radical scavenging activities, preventing lipid peroxidation, and protecting the erythrocytes in glucose-6-phosphate dehydrogenase-deficient individuals, although these effects have not been fully proved. The present study aimed to comprehensively review the evidence concerning the positive physiological and pharmacological properties of PYC, with an emphasis on the therapeutic potential of this natural component for enhancing human health.

Abstract
The aim of the study was to provide an in-depth characterization of the methanol-aqueous extract from the aerial parts of Gypsophila glomerata Pall. Ex Adams (Caryophyllaceae) (EGG) and to assess its protective potential on carbon tetrachloride (CCl4)-induced liver and kidney damage in male Wistar rats. Twenty-two flavonoid C-, O- and C,O--glycosides in EGG were annotated by mass spectrometry--based molecular networking; nine of them are reported in this species for the first time. Fourteen-day oral administration of EGG at a dose 200 mg kg-1 bm prevented significantly CCl4-induced liver injury, discerned by an amelioration of the markers of oxidative stress (GSH and MDA) and transaminase activity. EGG decreased the serum level of urea and creatinine as well. The observed improvement of biochemical parameters was supported by histopathological observations. The protective hepatorenal effects of EGG, rich in 2"-О-pentosyl-6-С-hexosyl-apigenin/luteolin/ methylluteolin and their acetyl- and methoxycinnamoyl-derivatives, were comparable with the effects of the positive control silymarin.

Abstract
This study set out to optimize simvastatin (SV) in lipid nanoparticles (SLNs) to improve bioavailability, efficacy and alleviate adverse effects. Simvastatin-loaded solid lipid nanoparticles (SV-SLNs) were prepared by hot-melt ultrasonication method and optimized by box-Behnken experimental design. Sixty Wister albino rats were randomly assigned into six groups and treated daily for 16 weeks: control group, the group fed with 20 g of high-fat diet (HFD), group treated with vehicle (20 mg/kg, P.O.) for last four weeks, group treated with HFD and SV (20 mg/kg, P.O.) / or SV-SLNs (20 mg/kg/day, P.O.) / or SV-SLNs (5 mg/kg, P.O.) at last four weeks. Blood, liver tissues, and quadriceps muscles were collected for biochemical analysis, histological and immunohistochemical assays. The optimized SV-SLNS showed a particle-size 255.2 ± 7.7 nm, PDI 0.31 ± 0.09, Zeta-potential - 19.30 ± 3.25, and EE% 89.81 ± 2.1%. HFD showed severe changes in body weight liver functions, lipid profiles, atherogenic index (AIX), albumin, glucose, insulin level, alkaline phosphatase as well as muscle injury, oxidative stress biomarkers, and protein expression of caspase-3. Simvastatin treatment in animals feed with HFD showed a significant improvement of all tested parameters, but it was associated with hepatotoxicity, myopathy, and histological changes in quadriceps muscles. SV-SLNs exhibited a significant improvement of all biochemical, histological examinations, and immunohistochemical assays. SV-SLNs (5 mg/kg) treatment returns all measured parameters to control itself. These results represent that SV-SLNs is a promising candidate as a drug carrier for delivering SV with maximum efficacy and limited adverse reaction.

Abstract
Drug-induced liver injury (DILI) has become a significant health care problem worldwide. Centella asiatica (L.) urban was traditionally used to prevent or treat various diseases, yet whether it works on hepatic injury remains unclear. In this study, multiple experimental models with different damage degrees and types of liver injury have been established to evaluate the hepatoprotective effects of an n-butanol extract of Centella asiatica (CA-BU). Our results revealed that CA-BU improved hepatocyte L02 cells survival from H2 O2 -induced oxidative damage in a concentration-dependent manner. We further verified the hepatoprotective effects of CA-BU in mice models of acetaminophen-induced acute liver injury (one of the most common DILIs clinically) and CCl4 -induced acute chemical liver injury, and a rat model of chronic alcoholic steatohepatitis. Furthermore, network pharmacology approaches were performed to explore the underlying mechanisms, and we predicted AKT1, EGFR, VEGFA, and STAT3 as the potential therapeutic targets. In follow-up studies, we will focus on targets verification and provide a deeper insight into the mechanisms of CA-BU against liver damage. Finally, we hope that these findings will provide new ideas and insights for the treatment of acute or chronic liver injury in the clinic.

Abstract
Gallic acid (GA) is a known phenolic compound with anti-inflammatory, antioxidant, and anti-cancer activities. The objective of this research is to evaluate the preventive role of GA against carbon tetrachloride (CCl4) induced liver fibrosis. Thirty-five (35) male Wistar rats were used in this study and were equally distributed into five groups (7 rats each). All groups were acclimatized for a week, Group I (control) rats were administered distilled water only. Group II rats were induced with a single dose of CCl4 (1.25 mL/kg in olive oil (1:1); IP) to cause hepatic damage, while Groups III, IV, and V, rats were intoxicated with CCl4. After 24 h the rats in groups III, IV, and V were given 50 mg/kg of silymarin, 50 mg/kg of GA, and 100 mg/kg of GA daily for one week respectively. Rats were sacrificed and fasting blood was estimated for biochemical analysis while the liver was excised for molecular studies. Results from this study revealed that GA significantly decreases serum hepatic enzymes, down-regulate the expression of pro-inflammatory cytokines, interleukin 1 beta (IL-1B), interleukin 6 (IL-6), cyclooxygenase 2 (COX 2), and tumor necrosis factor-alpha (TNF α), and up-regulate antioxidant gene expression (superoxide dismutase and catalase). The use of gallic acid as natural antioxidants can be promising in ameliorating liver diseases.

Brazilian Green Propolis Inhibits Ox-LDL-Stimulated Oxidative Stress in Human Umbilical Vein Endothelial Cells Partly through PI3K/Akt/mTOR-Mediated Nrf2/HO-1 Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:5789574.

Abstract
Propolis has been widely used as a dietary supplement for its health benefits, including cardiovascular protective effects. The aim of this study was to investigate the cytoprotective effects of Brazilian green propolis (BP) against oxidized low-density lipoprotein (Ox-LDL) induced human umbilical vein endothelial cells (HUVECs) damage. Our results suggested that treatment with BP rescued Ox-LDL-stimulated HUVECs cell viability losses, which might be associated with its inhibitive effects on the cell apoptosis and autophagy. We also noticed that BP restored Ox-LDL-stimulated HUVECs oxidative stress, by induced antioxidant gene expressions, including Heme oxygenase-1 and its upstream mediator, Nrf2, which were mediated by the activation of the phosphorylation of PI3K/Akt/mTOR. Pretreatment with wortmannin, PI3K/AKT inhibitor, abolished BP induced Nrf2 nuclear translocation and HO-1 level. Our results demonstrated that BP protected HUVECs against oxidative damage partly via PI3K/Akt/mTOR-mediated Nrf/HO-1 pathway, which might be applied into preventing Ox-LDL mediated cardiovascular diseases.

Abstract
Pycnogenol® (PYC) has already being used as a food supplement and herbal medicine due to its potent antioxidant properties. The aim of the present study was to examine the protective effect of PYC on acetaminophen-induced acute liver injury in rats. The effect of PYC on acetaminophen-induced hepatotoxicity in rats was examined by determining biochemical parameters, in vitro antioxidant activity, histological assessment, and oxidative status in liver homogenates. The best antioxidant properties were demonstrated in methanolic extracts. Seven-day pretreatment with PYC suppressed elevation of CYP2E1 protein expression induced by administration of toxic dose of acetaminophen. PYC at 50 mg/kg showed the ability to significantly decrease malondialdehyde (MDA) level compared with the group received acetaminophen. Xanthine oxidase (XOD) enzyme activity was significantly elevated in acetaminophen-treated group compared with control, whereas concomitant administration of PYC in a dose of 50 mg/kg significantly reduced activity of this enzyme. Significant decrease of glutathione (GSH) hepatic content in acetaminophen-intoxicated rats compared with the control rats was improved by concomitant administration of PYC at 50 mg/kg. Protective effect of PYC on acetaminophen-induced acute liver injury in rats has showed the best in vitro antioxidant potential expressed in methanolic extract and consequent histological assessment and oxidative status in liver homogenates.

Abstract
BACKGROUND The rise of organic electronics represents one of the most prominent technological developments of the last two decades, with its interface with biological systems highlighting new directions of research. The "soft" nature of conducting polymers renders them unique platforms for cell-based microdevices, allowing their implementation in drug discovery, pharmaceutical effect analysis, environmental pollutant testing etc. METHODS Cellular adhesion, proliferation and viability experiments were carried out to verify the biocompatibility of a PEDOT conductive polymer surface. Cyclic voltammetry was employed for estimating the electrocatalytic activity of the renal cell/electrode interface. The nephrotoxicity agent CCl4 and the medicinal plant Salvia officinalis were used on the proposed assembly. Renal cell viability was also assayed through the MTT assay. RESULTS Renal cells were able to adhere and proliferate on the conducting polymer surface. Electrochemical responses of the polymer exhibited good correlation with cell number and CCl4 concentration. Amelioration of the CCl4-induced renotoxicity by co-incubation with Salvia officinalis extract was demonstrated by both the MTT assay and the electrode's capacitance. CONCLUSIONS A conducting polymer-based bioelectrochemical assembly was established for in vitro mammalian cytotoxicity/cytoprotection assessment, employing renal cell monolayers as the primary transducers for signal generation and biological sensing. GENERAL SIGNIFICANCE The knowledge on PEDOT mammalian cell biocompatibility and possible applications was expanded. The proposed interdisciplinary approach connects soft electronics with biology and could provide a useful tool for preliminary crude drug screening and bioactivity studies of natural products or plant extracts in vitro.

Abstract
The aim of this study was to investigate the effect of Asphodeline lutea (L.) Rchb. dry root extract (ALE) administered alone and against carbon tetrachloride (CCl4)-induced liver injury in vitro/in vivo. The dried roots of A. lutea were extracted with 70% ethanol and was characterized with HPLC-UV. Hepatoprotective potential was investigated by in vivo/in vitro assays in Wistar rats as well as antioxidant properties. At concentrations ranging from 10 to 200μg/mL of ALE significant cytotoxic effects on isolated hepatocytes were found. ALE showed some toxicity in Wistar rats discerned by increased ALT (Alanine transaminase), ALP (Alkaline phosphatase) activities and MDA (malondialdehyde) quantity, decreased GSH (reduced glutathione) levels without affecting the activity of the antioxidant enzymes (GPx (Gluthatione peroxidase), GR (Glutathione reductase) and GST (Glutathione-S-transferase activity)). The antioxidant and hepatoprotective potential of ALE was also observed in vitro/in vivo against CCl4-induced liver injury, where ALE normalizes all the examined parameters perturbated by CCl4 administration. In addition, ALE preserved the decreased cytochrome P450 level and EMND (Ethylmorphine-N-Demethylase) activity without affecting AH (Aniline 4-Hydroxylase) activity. ALE is rich in anthraquinones, naphthalenes and caffeic acid. The pro-oxidant effects of ALE could be due to naphthalene and anthraquinone bioactivation pathways involving toxic metabolites.

Leishmanial lipid affords protection against oxidative stress induced hepatic injury by regulating inflammatory mediators and confining apoptosis progress. Toxicol Lett 2014; 232:499-512.

Abstract
Persistence of liver injury alters the internal milieu, promotes deregulation of inflammatory factors, and leads to dysplastic lesions like fibrosis, cirrhosis to hepatocellular carcinoma. Our previous study revealed that leishmanial lipid (pLLD) exerts potential anti-inflammatory activity in sepsis associated hepatic injury. We now show that pLLD gives protection against chemical induced hepatotoxicity in murine system. The beneficial effect of treatment with pLLD on such hepatic injury in mice was analyzed using different assays including ELISA, FACS, western blot and immunohistochemical analysis. pLLD significantly suppressed serum enzymes and rectified the histopathological alteration to induce the antioxidant level in CCl4 intoxicated liver. Levels of several growth factors including TGF-β, HGF, and EGF were significantly improved in serum and hepatic tissue with consequent reduction of caspase activities and expressions of Bad, Bax, p53, and NF-κBp65. Moreover, pLLD modulated inflammatory responses by decreasing the production of several cytokines and chemokines, thus preventing the infiltration of immune cells to the damaged area. It accelerated the repair process in liver damage with modulation of signalling cascade via alteration of apoptotic factors. Our experimental approaches suggest that pLLD effectively prevents liver injury mainly through down regulation of oxidative stress and inflammatory response towards anti-apoptotic changes.

Abstract
OBJECTIVE To investigate the hepatoprotective potential of n-butanolic extract of Astragalus monspessulanus L. (EAM) against in-vitro/in-vivo carbon tetrachloride (CCl4)-induced liver damage in rats. Silymarin was used as a positive control. METHODS AND RESULTS The in-vitro experiments were carried out in primary isolated rat hepatocytes first incubated with CCl4 (86 µmol/l). Hepatic injury was discerned by a decrease in cell viability and cell glutathione (GSH) levels, an increase in lactate dehydrogenase leakage into the medium, and an elevation in malondialdehyde (MDA) quantity. Cell pre-incubation with EAM (1 µg/ml and 10 µg/ml) significantly ameliorated the CCl4-induced liver damage. In-vivo rats were challenged orally with CCl4 (10% solution in olive oil) alone and after 7 days pre-treatment with EAM (100 mg/kg body weight per day, oral gavage). CCl4 damage was judged by an increased production of MDA, depletion of cell GSH, and a decrease in cell antioxidant defense system. EAM pre-treatment normalizes the activities of the antioxidant enzymes and the levels of GSH and MDA. These data are supported by the histopathological examination. CONCLUSION These results indicate that EAM has a similar significant protective effect, in vitro and in vivo, against CCl4 induced hepatotoxicity in rat as silymarin.This may be due to its antioxidant and membrane stabilizing properties.

Abstract
This study investigated the hepatoprotective activity of saponarin, isolated from Gypsophila trichotoma Wend., using in vitro/in vivo hepatotoxicity model based on carbone tetrachloride (CCl₄)-induced liver damage in male Wistar rats. The effect of saponarin was compared with those of silymarin. In vitro experiments were carried out in primary isolated rat hepatocytes. Cell incubation with CCl₄ (86 μmol l⁻¹) led to a significant decrease in cell viability, increased LDH leakage, decreased levels of cellular GSH and elevation in MDA quantity. Cell pre-incubation with saponarin (60-0.006 μg/ml) significantly ameliorated CCl₄-induced hepatic damage in a concentration-dependent manner. These results were supported by the following in vivo study. Along with decreased MDA quantity and increased level of cell protector GSH, seven day pre-treatment of rats with saponarin (80 mg/kg bw; p.o.) also prevented CCl₄ (10%, p.o.)-caused oxidative damage by increasing antioxidant enzyme activities (CAT, SOD, GST, GPx, GR). Biotransformation phase I enzymes were also assessed. Administered alone, saponarin decreased EMND and AH activities but not at the same extent as CCl₄ did. However, pre-treatment with saponarin significantly increased enzyme activities in comparison to CCl₄ only group. The observed biochemical changes were consistent with histopathological observations where the hepatoprotective effect of saponarin was comparative to the effects of the known hepatoprotecor silymarin. Our results suggest that saponarin, isolated from Gypsophila trichotoma Wend., showed in vitro and in vivo hepatoprotective and antioxidant activity against CCl₄-induced liver damage.

Abstract
Lentinus edodes is the medicinal macrofungus showing potential for therapeutic applications in infectious disorders including hepatitis. In an attempt to develop the agent for handling hepatic injury, we used the extracts of Lentinus edodes mycelia (LEM) to screen the effect on hepatic injury in rats induced by carbon tetrachloride (CCl4). Intraperitoneal administration of CCl4 not only increased plasma glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) but also decreased hepatic superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels in rats. Similar to the positive control silymarin, oral administration (three times daily) of this product (LEM) for 8 weeks significantly reduced plasma GOT and GPT. Also, the activities of antioxidant enzymes of SOD and GPx were elevated by LEM. in liver from CCl4-treated rats, indicating that mycelium can increase antioxidant-like activity. Moreover, the hepatic mRNA and protein levels of SOD and GPx were both markedly raised by LEM. The obtained results suggest that oral administration of the extracts of Lentinus edodes mycelia (LEM) has the protective effect against CCl4-induced hepatic injury in rats, mainly due to an increase in antioxidant-like action.

Abstract
Oxidative stress is considered as a mechanism of hepatocellular injury in non-alcoholic steatohepatitis (NASH). Pycnogenol (PYC) is the natural plant extract from the bark of Pinus pinaster Aiton. and has potent antioxidant activities. We studied the protective effect of PYC on excessive fat accumulation in the liver fed a methionine-choline deficient (MCD) high-fat diet for 6 weeks. Pycnogenol (10 mg/kg body weight) was orally administered for 5 weeks. At the end of the experiment, blood and liver samples were collected and assessed for effects of PYC by histopathological and biochemical analyses. Histopathological analyses of liver tissues stained with Azan-Mallory showed hepatic macrovesicular steatosis and fibrosis in MCD-fed rats. Supplementation of PYC prevented this effect. Pycnogenol treatment significantly decreased the liver triglyceride and serum alanine amino transferase levels. Our results indicated that orally administered PYC may serve to prevent NASH-induced liver damage.

Abstract
INTRODUCTION Oxygen free radicals are involved in pathophysiology of ischemia/reperfusion (I/R) injury. This study was designed to assess the possible protective effect of pycnogenol (PYC) against I/R-induced oxidative renal damage. MATERIALS AND METHODS Wistar albino rats were unilaterally nephrectomized and subjected to 45 min of renal pedicle occlusion followed by 3 h of reperfusion. PYC (10 mg kg(-1), i.p.) or saline was administered at 15 min prior to ischemia and immediately before the reperfusion period. At the end of the 3 h, rats were decapitated and trunk blood was collected. Creatinine, blood urea nitrogen (BUN), and lactate dehydrogenase (LDH) activity were measured in the serum samples, while proinflammatory cytokines, TNF-alpha, IL-1beta, and IL-6 levels were assayed in plasma samples. Kidney samples were taken for the determination of tissue malondialdehyde (MDA), glutathione (GSH) levels, Na+, K+-ATPase, and myeloperoxidase (MPO) activities, and the extent of tissue injury was analyzed microscopically. RESULTS Ischemia/reperfusion caused a significant decrease in tissue GSH level and Na+, K+-ATPase activity, which was accompanied with significant increases in the renal MDA level and MPO activity. Similarly, serum creatinine and BUN levels, as well as LDH and IL-1beta, IL-6, and TNF-alpha levels, were elevated in the saline-treated I/R group as compared to saline-treated control group. On the other hand, PYC treatment reversed all these biochemical indices, as well as histopathological alterations that were induced by I/R. CONCLUSIONS Findings of the present study suggest that pycnogenol exerts renoprotective effects, via its free radical scavenging and antioxidant activities, that appear to involve the inhibition of tissue neutrophil infiltration.

Abstract
Environmental and occupational exposure to chromium compounds, especially hexavalent chromium [Cr(VI)], is widely recognized as a potential nephrotoxic in humans and animals. Its toxicity is associated with overproduction of free radicals, which induces oxidative damage. Recent evidence indicates that Pycnogenol (PYC), French maritime pine bark extract, exhibits antioxidant potential and protects against various oxidative stressors. The aim of the present study was to examine the modulating impacts of PYC on potassium dichromate K2Cr2O7-induced oxidative damage and nephrotoxicity in rats. Male Wistar rats were divided into four groups. The first group was control, the second group was control plus pre-treated with PYC (10 mg/kg, body weight; in saline; intraperitoneally; once daily for 3 weeks) as drug control and the third group was saline pre-treated plus treated with a single injection of K2Cr2O7 (15 mg/kg, body weight; in saline; intraperitoneally) as toxicant group. The fourth group was PYC pre-treated plus K2Cr2O7 injected. Forty-eight hours after K2Cr2O7-treatment, blood was drawn for estimation of renal injury markers in serum. Rats were then sacrificed, and their kidneys were dissected for biochemical and histopathological assays. K2Cr2O7-treated rats showed significant increases in markers of renal injury in serum, including blood urea nitrogen (BUN), serum creatinine (Scr), and alkaline phosphatase (ALP), which were significantly (P < 0.05) decreased by PYC pre-treatment. Moreover, prophylactic pre-treatment of rats with PYC significantly (P < 0.05) ameliorated increased thiobarbituric reactive substances (TBARS), malonaldehyde (MDA) and protein carbonyl (PC), and decreased levels of glutathione (GSH) and catalase activity in the kidney homogenate of K2Cr2O7-treated rats. These results were also supported and confirmed with histopathological findings. The study suggests that PYC is effective in preventing K2Cr2O7-induced oxidative mediated nephrotoxicity, but more studies are needed to confirm the effects of PYC as a nephroprotective agent.

Abstract
AIM: To investigate the effect of magnesium isoglycyrrhizinate (MI) on acute liver injury induced by carbon tetrachloride (CCl4) in mice and its relationship with the expression of nuclear factor kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) in liver tissues.
METHODS: Thirty male Kunming mice (28 ± 2.2 g) were divided randomly into 3 groups: model group, normal control group and MI-treated group. The model of acute liver injury was established by intraperitoneal injection of 1% CCl4 (0.1 mL/10 g). The mice in normal control group and MI-treated group were injected with sterile saline, and furthermore, the MI-treated mice were intraperitoneally injected with MI (15 mg/kg, once per day for five days) 15 min before CCl4 injection. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and tissue contents of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured using biochemical method. SP immunohistochemistry was used to detect NF-κB and ICAM-1 expression. The pathological alterations were observed after HE staining.
RESULTS: The serum levels of AST, ALT and tissue content of MDA were significantly increased in model group as compared with those in normal control group (465.10 ± 35.90 kU/L vs 47.40 ± 4.13 kU/L; 582.37 ± 25.63 kU/L vs 116.06 ± 12.82 kU/L; 4.07 ± 0.38 nmol/mg vs 1.39 ± 0.03 nmol/mg; all P < 0.01), but tissue content of SOD was significantly decreased (29.71 ± 2.25 U/mg vs 87.02 ± 4.84 U/mg, P < 0.01). NF-κB and ICAM-1 were not expressed in normal control group, but obviously expressed in model group. In comparison with those in model group, the tissue expression of NF-κB and ICAM-1 in MI-treated group were decreased in concurrence with the alleviation of liver injury as well as a statistically significant decrease in AST (263.51 ± 22.89 kU/L), ALT (292.56 ± 26.01 kU/L) and MDA (2.17 ± 0.03 nmol/mg, P < 0.05) and increase in SOD (58.04 ± 2.56 U/mg, P < 0.01) in hepatic homogenate.
CONCLUSION: NF-κB and ICAM-1 are strongly expressed in acute liver injury in mice. MI can protect mice against CCl4-induced acute liver injury by suppressing NF-κB activation and subsequent expression of ICAM-1.
