Aljutaily T, Almutairi SM, Alharbi HF. The Nephroprotective Potential of Brassica nigra Sprout Hydroalcoholic Extract against Carbon Tetrachloride-Induced Renal Toxicity in Rats. Foods 2023; 12:3906. [PMID: 37959024 PMCID: PMC10648930 DOI: 10.3390/foods12213906] [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: 10/03/2023] [Revised: 10/19/2023] [Accepted: 10/23/2023] [Indexed: 11/15/2023] Open
Abstract
The nephroprotective potential of the Brassica nigra sprout (BNS) hydroalcoholic extract against carbon tetrachloride (CCl4)-induced renal toxicity in rats was the object of this study. B. nigra sprouts were prepared in the lab to monitor the bio-changes in bioactive compounds during the sprouting for up to 7 days at 17 ± 1 °C and 90% relative humidity. Subsequently, 6-day sprouts of B. nigra were selected according to their phenolics and antioxidant activity, extracted, and examined for their nephroprotective and antioxidative stress potential at 250 and 500 mg sprout extracts kg-1 bw, in vivo. Weight gain, organ weight, lipid profile, atherogenic index, kidney functions, and oxidative stress biomarkers were assessed. The results indicated that the most proficient treatment for weight gain improvement was BNS extract at 500 mg kg-1. BNS at 250 mg kg-1 was remarked as the lowest weight gain enhancer compared to the NR group. A significant increase in TG, TC, LDL-c, and VLDL-c levels in the rats with CCl4-induced renal toxicity, and a significant decrease in HDL level, was noted. The administration of the BNS extract at 250 and 500 mg kg-1 considerably attenuated TG, TC, LDL-c, and VLDL-c levels, compared to the NR group. The most efficient treatment for improving the lipid profile was the BNS extract at 500 mg kg-1, even better than 250 mg kg-1. Administrating the BNS extract substantially attenuated the alterations in the creatinine, urea, and BUN caused by the CCl4 injection. The most efficient improvement was markedly recorded with the BNS extract at 500 mg kg-1, compared to the NR group. The rats treated with the BNS extract showed significant enhancement in GSH, CAT, and SOD activities and a considerable reduction in MDA levels. Administering the BNS extract at 250 and 500 mg kg-1 can efficiently reverse CCl4 inhibition of antioxidant enzyme activities, significantly increase GSH, CAT, and SOD, and decrease the MDA levels dose-dependently. The BNS extract at 250 and 500 mg kg-1 exhibits nephroprotection and antioxidative stress in a dose-dependent matter. The total nephroprotection % was recorded at 65.18% and 99.21% for rats treated with 250 and 500 mg kg-1, respectively. These findings could prove and potentiate the nephroprotective activities of the BNS extract in the range of the given doses. Further clinical studies are highly recommended for confirming the nephroprotection efficiency of the B. nigra sprout.

Salvia miltiorrhiza extract may exert an anti-obesity effect in rats with high-fat diet-induced obesity by modulating gut microbiome and lipid metabolism. World J Gastroenterol 2022; 28:6131-6156. [PMID: 36483153 PMCID: PMC9724488 DOI: 10.3748/wjg.v28.i43.6131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/21/2022] [Accepted: 10/31/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Studies have shown that a high-fat diet (HFD) can alter gut microbiota (GM) homeostasis and participate in lipid metabolism disorders associated with obesity. Therefore, regulating the construction of GM with the balance of lipid metabolism has become essential for treating obesity. Salvia miltiorrhiza extract (Sal), a common traditional Chinese medicine, has been proven effective against atherosclerosis, hyperlipidemia, obesity, and other dyslipidemia-related diseases.
AIM To investigate the anti-obesity effects of Sal in rats with HFD-induced obesity, and explore the underlying mechanism by focusing on GM and lipid metabolism.
METHODS Obesity was induced in rats with an HFD for 7 wk, and Sal (0.675 g/1.35 g/2.70 g/kg/d) was administered to treat obese rats for 8 wk. The therapeutic effect was evaluated by body weight, body fat index, waistline, and serum lipid level. Lipid factors (cAMP, PKA, and HSL) in liver and fat homogenates were analyzed by ELISA. The effect of Sal on GM and lipid metabolism was assessed by 16S rRNA-based microbiota analysis and untargeted lipidomic analysis (LC-MS/MS), respectively.
RESULTS Sal treatment markedly reduced weight, body fat index, serum triglycerides (TG), total cholesterol (TC), low-density lipoprotein, glucose, free fatty acid, hepatic lipid accumulation, and adipocyte vacuolation, and increased serum high-density lipoprotein (HDL-C) in rats with HFD-induced obesity. These effects were associated with increased concentrations of lipid factors such as cAMP, PKA, and HSL in the liver and adipose tissues, enhanced gut integrity, and improved lipid metabolism. GM analysis revealed that Sal could reverse HFD-induced dysbacteriosis by promoting the abundance of Actinobacteriota and Proteobacteria, and decreasing the growth of Firmicutes and Desulfobacterita. Furthermore, LC-MS/MS analysis indicated that Sal decreased TGs (TG18:2/18:2/20:4, TG16:0/18:2/22:6), DGs (DG14:0/22:6, DG22:6/22:6), CL (18:2/ 18:1/18:1/20:0), and increased ceramides (Cers; Cer d16:0/21:0, Cer d16:1/24:1), (O-acyl)-ω-hydroxy fatty acids (OAHFAs; OAHFA18:0/14:0) in the feces of rats. Spearman’s correlation analysis further indicated that TGs, DGs, and CL were negatively related to the abundance of Facklamia and Dubosiella, and positively correlated with Blautia and Quinella, while OAHFAs and Cers were the opposite.
CONCLUSION Sal has an anti-obesity effect by regulating the GM and lipid metabolism.

Abstract
Organ fibrosis is a common pathological change that finally results in organ failure, which involves the destruction of parenchyma cells, the activation of mesenchymal cells and the imbalance of immunological cells. In recent years, although some breakthroughs have been made in understanding the pathogenesis and therapeutics of organ fibrosis, no registered drugs could directly target the fibrotic process, which constitutes a major biomedical challenge. Salvia miltiorrhiza (SM) is a well-known medicinal plant in China, which has been widely applied because of its pharmacological effects on anti-oxidative, anti-myocardial infarction, anti-fibrotic, anti-inflammatory, and anti-neoplastic properties. Accumulated evidence suggested that SM played critical roles against organ fibrosis in vivo and in vitro experiments by its multiple biological compounds. In this review, we discussed the recent advances on the phytochemistry and pharmacological mechanisms of SM and its active ingredients in liver, lung, kidney, and heart fibrosis, which might help to promote the treatment of fibrotic diseases in thorax and abdomainal viscera in clinic.

Eicosapentaenoic acid loaded silica nanoemulsion attenuates hepatic inflammation through the enhancement of cell membrane components. Biol Proced Online 2022; 24:11. [PMID: 36071378 PMCID: PMC9454130 DOI: 10.1186/s12575-022-00173-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 08/16/2022] [Indexed: 11/23/2022] Open
Abstract
Background Liver inflammation is a multistep process that is linked with cell membrane fatty acids composition. The effectiveness of eicosapentaenoic acid (EPA) undergoes an irreversible change during processing due to their unsaturated nature; so the formation of nanocarrier for EPA is crucial for improving EPA’s bioavailability and pharmacological properties. Objective In this study we aimed to evaluate the efficiency of EPA alone or loaded silica nanoemulsion on the management of hepatic inflammation induced by diethyl nitrosamine (DEN) through the enhancement of the cell membrane structure and functions. Methods The new formula of EPA was prepared to modify the properties of EPA. Forty-eight male Wistar albino rats were classified into: control, EPA, EPA loaded silica nanoemulsion (EPA–NE), DEN induced hepatic inflammation; DEN induced hepatic inflammation treated with EPA or EPA –NE groups. Plasma tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), liver hydroxyproline (Hyp) content, and liver oxidant and anti-oxidants were estimated. Urinary 8- hydroxyguanozine (8- OHdG) and erythrocyte membrane fatty acids fractions were estimated by High-performance liquid chromatography (HPLC). Also, histopathology studies were done to verify our hypothesis. Results It was appeared that administration of EPA, in particular EPA loaded silica nanoemulsion, ameliorated the inflammatory response, increased the activity of the anti-oxidants, reduced levels of oxidants, and improved cell membrane structure compared to hepatic inflammation induced by DEN group. Histopathological examination confirmed these results. Conclusion EPA and notably EPA loaded silica nanoemulsion strongly recommended as a promising supplement in the management of hepatic inflammation.

Abstract
Seven new phenolic acids, 7, 8-epiblechnic acid (1), 8-epiblechnic acid 9-ehthyl-9'-methyl ester (2), 9'-ehyl-isolithospermate (3), 9''-methyl-isolithospermate (4), 9'-ethyl-9''-methyl-isolithospermate (5), 9', 9''-dimethyl-isolithospermate (6), sebesteniod E (7), were isolated from the roots of Salvia miltiorrhiza. Their structures were elucidated by detailed spectroscopic means including UV, IR, HRESIMS, and NMR data spectra. The bioactive assays of compounds 1-7 against neuroprotection activities were determined. The results suggested that compound 4 exhibited a moderate glutamate-induced neuroprotective activity and the cell survival rate was 24.0% (10-5 mol/L), while compound 2 showed weak activity (survival rate: 7.58%, 10-5 mol/L), using PHPB (survival rate: 7.56%, 10-5 mol/L) as positive control.

Abstract
Peritoneal fibrosis is a devastating complication in patients undergoing peritoneal dialysis, with no definite therapy yet available. Salvia miltiorrhiza and its major active component Salvianolic acid A (Sal A) have demonstrated a beneficial effect in myriad diseases. However, their effect on peritoneal fibrosis is unknown. In murine models of peritoneal dialysis, daily Sal A treatment substantially improved the peritoneal dialysis fluid (PDF) elicited peritoneal fibrosis, marked by thickening of the submesothelial compact zone, accumulation of extracellular matrix and increased expression of vimentin and PAI-1, concomitant with attenuation of GSK3β hyperactivity. This coincided with diminished nitrotyrosine in peritoneal tissues and increased Nrf2 nuclear translocation, entailing a lessened oxidative injury and reinforced Nrf2 antioxidant response. Meanwhile, inflammatory infiltration and maladaptive angiogenesis in peritoneal tissues provoked by PDF injury were also mitigated by Sal A, associated with a suppressed NFκB activation. Mechanistically, ectopic expression of the constitutively active GSK3β blunted the NFκB-suppressing and Nrf2-activating efficacy of Sal A in peritoneal mesothelial cells exposed to hypertonic dextrose, suggesting that GSK3β inhibition mediates the protective effect of Sal A. Collectively, our findings may open the avenue for developing a novel therapy based on Sal A for preventing peritoneal fibrosis in peritoneal dialysis.

Abstract
INTRODUCTION AND OBJECTIVES The activation of hepatic stellate cells (HSCs) is the main cause of liver fibrosis. The beneficial effects of fibroblast growth factor (FGF) 19 on liver fibrosis were recently reported. The S. miltiorrhiza as well as S. miltiorrhiza derived bioactive chemical components has shown prominent antifibrotic effects in liver fibrosis but the mechanism is still not fully understood. We aimed to investigate the bioactive compounds derived from S. miltiorrhiza which exerts antifibrotic effects in HSCs via regulating FGF19. MATERIALS AND METHODS FGF19 level in culture media was determined by enzyme-linked immunosorbent assay. Cell proliferation was measured by Cell Counting Kit-8 assay. Further, mRNA and protein expressions were assessed by quantitative polymerase chain reaction and western blotting, respectively. Knocking down of FGF receptor 4 (FGFR4) by transfection with siRNA was used to confirm the role of FGF19/FGFR4 signaling. RESULTS Using the human HSC cell line LX-2, we screened several natural products and found that bioactive compounds isolated from Salvia miltiorrhiza, particularly salvianolic acid B, strongly upregulated FGF19 secretion by LX-2 cells. We further showed that salvianolic acid B inhibited lipopolysaccharide (LPS)-induced HSC proliferation and activation. LPS treatment may also reduce the mRNA and protein levels of FGF19 and its receptor FGFR4. Salvianolic acid B treatment restored the impaired expressions of FGF19 and FGFR4. Finally, FGFR4 knockdown abolished the antifibrotic effects of salvianolic acid B in the LPS-induced HSC activation model. CONCLUSIONS Salvianolic acid B prevented LPS-induced HSC proliferation and activation by enhancing antifibrotic FGF19/FGFR4 signaling.

Abstract
The South African Salvia species, Salvia africana-lutea, S. lanceolata and S. chamelaeagnea, are widely used to treat fever and inflammation associated with skin and lung infections. The aim of this study was to explore the non-volatile secondary metabolites and the phytochemical variation within these lesser known species, to support product development and commercialisation. Chemical profiles of the methanol extracts of 81 wild-harvested samples were obtained using ultra performance-quadrupole-Time-of-Flight-mass spectrometry (UPLC-qToF-MS). Forty-one compounds, including caffeic acid, rosmarinic acid, carnosol, carnosic acid and ursolic acid, were detected and confirmed across the three species. Nineteen compounds were tentatively identified of which 14 have not been reported in these species. Principal component analysis revealed distinct clusters corresponding to the three species, confirming chemical differences. Marker compounds for each species were revealed using orthogonal projection to latent structures-discriminant analysis. Further chemometric analysis reflected a degree of intraspecies variation, although the chemistry within populations was mostly conserved. Potential chemotypes for each species were identified through unique compounds associated with each group. The concentrations of medicinally important metabolites, namely, rosmarinic acid, carnosol, carnosic acid and ursolic acid, were determined, using validated UPLC-PDA methods. Ursolic acid was present at levels up to 38.2 mg/g, confirming that these species are a rich source of this compound. No similar studies combining liquid chromatography with chemometric analysis, and utilising a large sample size from various habitats, have been reported for these three Salvia species. The results will guide selection of cultivars with the best attributes for the intended therapeutic application, thereby protecting wild populations from over-exploitation.

Abstract
Background One of the most prevalent postoperative complications is believed to be intra-abdominal peritoneal adhesions, which is followed by several complications. Several adhesion prevention products have been examined, yet none of them were found to be completely effective. The current research is conducted to evaluate the beneficial effects of Salvia miltiorrhiza hydroalcoholic extract in inhibiting postoperative peritoneal adhesions in rats. Methods Forty rats were randomly classified into five equal groups (n = 8): 1) the normal group did not undergo surgical operations, 2) the control group in which the adhesion was induced, and which did not receive any treatment, 3) distilled water group that received distilled water, and 4,5) treatment groups treated with 1 and 5% of Salvia miltiorrhiza hydroalcoholic extract. The rats were euthanized 14 days following the surgery and the macroscopic score, the microscopic score of granulomatous inflammation and granulation tissue formation, IHC markers (vimentin, CD31, IL-1β, COX-2, and iNOS), and oxidative stress biomarkers (MDA, GPx, CAT, and TAC) were assessed in the experimental groups of the study. Results The difference between the control group and other groups for the adhesions macroscopic score, microscopic score, IHC markers, and oxidative stress biomarkers was significant (p < 0.05). Distilled water had no protective effect on the formation of peritoneal adhesions. Salvia miltiorrhiza treatment in two different doses significantly reduced macroscopic and microscopic scores, MDA concentration, Vimentin, IL-1β, COX-2, and iNOS compared to the control group (p < 0.05). The levels of GPx, CAT, and TAC in the treatment groups increased significantly compared with the control group (p < 0.05). Our findings revealed that a higher dose of Salvia miltiorrhiza was more effective in reducing peritoneal adhesions, proinflammatory and mesenchymal cell markers, and oxidative stress. Conclusions Salvia miltiorrhiza extract, owing to its strong antioxidant and anti-inflammatory properties, could effectively reduce peritoneal adhesions. Therefore, Salvia miltiorrhiza is recommended to be used as an effective anti-peritoneal post-operative adhesive agent.

Abstract
Testicular torsion/detorsion is one of the important emergencies that requires fast surgical intervention. This study aimed to investigate the effects of Salvia miltiorrhiza hydroalcoholic extract combined with verapamil on testicular ischaemia/reperfusion damage in Wistar albino rats. All animals were distributed in 3 groups (n = 8), including the sham-operated group, torsion/detorsion (TD) group and torsion/detorsion + pretreatment with 200 mg/kg Salvia miltiorrhiza extract combined with 0.3 mg/kg verapamil (SMV) group. Oxidative stress biomarkers (MDA, GPx, CAT and TAC) both in plasma and testicular tissue, sperm parameters (motility, vitality, concentration and morphology) and histopathological parameters (MSTD, GECT, Johnson's score, Cosentino's score and testicular cell thickness) were assessed in all groups. Ischaemia/reperfusion significantly increased MDA and decreased GPx, CAT and TAC levels (p < .05). Pretreatment with SMV significantly increased GPx, CAT and TAC levels (p < .05). SMV group increased progressive sperm motility and vitality and reduced non-progressive motility of spermatozoon (p < .05). Testicular torsion significantly decreased all histopathological parameters compared to the sham group (p < .05). SMV pretreatment remarkably increased MSTD, GECT and Cosentino's score in comparison with the TD group (p < .05). A combination of Salvia miltiorrhiza with verapamil could reduce damages triggered by testicular torsion detorsion and improve sperm functionality parameters and oxidative stress defence systems.

PHYTOCHEMISTRY 2020; 172:112249. [PMID: 31958659 DOI: 10.1016/j.phytochem.2019.112249] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 10/03/2019] [Accepted: 12/22/2019] [Indexed: 06/10/2023]
Abstract
Indigenous Salvia species from southern Africa are popular traditional medicines for the treatment of a variety of conditions. They produce fragrant volatiles that can be isolated as essential oils. Some of these volatile organic compounds may play a role in the biological activities of the extracts. Three indigenous Salvia species, Salvia africana-lutea, S. lanceolata and S. chamelaeagnea, were selected for this study as they are commonly used in traditional medicine in South Africa, and the essential oils from these species have potential for commercialisation. Although some studies have described the essential oil compositions and some biological activities, only single composite samples were used. The aim of this study was to investigate the intra- and interspecies variation of the essential oils, sampled over a wide geographical area and using a representative sample size, to encourage commercialisation of the essential oil. Essential oils were isolated from individual plants using conventional hydrodistillation of the aerial parts, harvested from several localities. Gas chromatography coupled simultaneously to mass spectrometry/flame ionisation detection (GC-MS/FID) was used to identify and quantify the volatile constituents. The essential oils of S. africana-lutea consisted mainly of terpinene-4-ol + β-caryophyllene (1.4 - 29.0%), T-cadinol (1.2 - 20.0%), α-eudesmol (trace - 23.0%) and β-eudesmol (trace - 26.0%), those of S. lanceolata comprised mainly terpinene-4-ol + β-caryophyllene (4.3 - 31.0%), α-humulene (2.3 - 15.0%), bicyclogermacrene (trace - 37.0%) and spathulenol (trace - 25.0%), while the essential oils of S. chamelaeagnea were characterised by δ-3-carene (trace - 18.0%), limonene (1.6 - 36.0%), viridiflorol (9.8 - 61.0%) and 1,8-cineole (not detected - 11.0%). The compounds identified in the essential oils of the three selected Salvia species have been identified in other Salvia essential oils. To add to the novelty of this study, the superior resolving power of two-dimensional gas chromatography was demonstrated through analysis of selected essential oils. Many additional compounds were identified, and previously co-eluting compounds were clearly separated. Chemometric modelling of the GC-MS data using SIMCA P+ 14 software allowed distinct clustering patterns to be discerned. The unsupervised principal component analysis model revealed separate clusters for the three species, confirming substantial chemical differences between their essential oils. Quantitative, rather than qualitative differences were evident when individual essential oil samples representing the same species, were compared. For each species, two chemically distinct groups were observed and unique marker compounds could be identified. This study has contributed detailed information on the major and minor volatile compounds present in the essential oils of the three Salvia species investigated.

Abstract
Phenolic acids are the major water-soluble components in Salvia miltiorrhiza (>5%). According to previous studies, many of them contribute to the cardiovascular effects and antioxidant effects of S. miltiorrhiza. Polymeric phenolic acids can be considered as the tanshinol derived metabolites, e.g., dimmers, trimers, and tetramers. A strategy combined with tanshinol-based expected compounds prediction, total ion chromatogram filtering, fragment ion searching, and parent list-based multistage mass spectrometry acquisition by linear trap quadropole-orbitrap Velos mass spectrometry was proposed to rapid profile polymeric phenolic acids in S. miltiorrhiza. More than 480 potential polymeric phenolic acids could be screened out by this strategy. Based on the fragment information obtained by parent list-activated data dependent multistage mass spectrometry acquisition, 190 polymeric phenolic acids were characterized by comparing their mass information with literature data, and 18 of them were firstly detected from S. miltiorrhiza. Seven potential compounds were tentatively characterized as new polymeric phenolic acids from S. miltiorrhiza. This strategy facilitates identification of polymeric phenolic acids in complex matrix with both selectivity and sensitivity, which could be expanded for rapid discovery and identification of compounds from complex matrix.

Abstract
Iron overload cardiomyopathy results from iron accumulation in the myocardium that is closely linked to iron-mediated myocardial fibrosis. Salvia miltiorrhiza (SM, also known as Danshen), a traditional Chinese medicinal herb, has been widely used for hundreds of years to treat cardiovascular diseases. Here, we investigated the effect and potential mechanism of SM on myocardial fibrosis induced by chronic iron overload (CIO) in mice. Kunming male mice (8 weeks old) were randomized to six groups of 10 animals each: control (CONT), CIO, low-dose SM (L-SM), high-dose SM (H-SM), verapamil (VRP) and deferoxamine (DFO) groups. Normal saline was injected in the CONT group. Mice in the other five groups were treated with iron dextran at 50 mg/kg per day intraperitoneally for 7 weeks, and those in the latter four groups also received corresponding daily treatments, including 3 g/kg or 6 g/kg of SM, 100 mg/kg of VRP, or 100 mg/kg of DFO. The iron deposition was estimated histologically using Prussian blue staining. Myocardial fibrosis was determined by Masson's trichrome staining and hydroxyproline (Hyp) quantitative assay. Superoxide dismutase (SOD) activity, malondialdehyde (MDA) content and protein expression levels of type I collagen (COL I), type I collagen (COL III), transforming growth factor-β1 (TGF-β1) and matrix metalloproteinase-9 (MMP-9) were analyzed to investigate the mechanisms underlying the effects of SM against iron-overloaded fibrosis. Treatment of chronic iron-overloaded mice with SM dose-dependently reduced iron deposition levels, fibrotic area percentage, Hyp content, expression levels of COL I and COL III, as well as upregulated the expression of TGF- β1 and MMP-9 proteins in the heart. Moreover, SM treatment decreased MDA content and increased SOD activity. In conclusion, SM exerted activities against cardiac fibrosis induced by CIO, which may be attributed to its inhibition of iron deposition, as well as collagen metabolism and oxidative stress.

Abstract
During chronic liver injury, hepatic stellate cells (HSC) are activated and proliferate, which causes excessive extracellular matrix (ECM) deposition, leading to scar formation and fibrosis. Medicinal plants are gaining popularity as antifibrotic agents, and are often safe, cost-effective, and versatile. This review aims to describe the protective role and mechanisms of medicinal plants in the inhibition of HSC activation and ECM deposition during the pathogenesis of liver fibrosis. A systematic literature review on the anti-fibrotic mechanisms of hepatoprotective plants was performed in PubMed, which yielded articles about twelve relevant plants. Many of these plants act via disruption of the transforming growth factor beta 1 signaling pathway, possibly through reduction in oxidative stress. This reduction could explain the inhibition of HSC activation and reduction in ECM deposition. Medicinal plants could be a source of anti-liver fibrosis compounds.

Abstract
Salvianolic acid B (Sal B), one of the major water-soluble compounds of Danshen (a popular Chinese herb), possesses many of the biological activities, such as antifibrogenic effect in liver and renal diseases. Transforming growth factor-β1 (TGF-β1) plays a central role in the development of pulmonary fibrosis by stimulating extracellular matrix (ECM) accumulation and activating fibroblasts. Here, we investigated the effects of Sal B on cell proliferation, collagen synthesis, endogenous TGF-β1 production, and α-smooth muscle actin (α-SMA, a marker of myofibroblasts) expression in human lung fibroblasts stimulated by TGF-β1 in vitro. The cell proliferation rates were analyzed by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide) assay. The expression of TGF-β1 and type I collagen at both the mRNA and protein levels was detected by reverse transcription polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), and radioimmunoassay, respectively. The α-SMA expression was detected by Western blot. TGF-β1 treatment of lung fibroblasts increased cell proliferation rates, and enhanced the expression level of type I collagen, endogenous TGF-β1 production, and α-SMA expression (P < .05). The treatment with only Sal B did not affect the proliferation and differentiation of lung fibroblasts. Interestingly, Sal B was found to inhibit TGF-β1-induced cell proliferation, expression of type I collagen, endogenous TGF-β1 production, and α-SMA expression in lung fibroblasts. Moreover, the inhibitory effect of Sal B on TGF-β1-induced proliferation and differentiation in lung fibroblasts was more significant when treated with high-dose Sal B (1 μmol/L versus 10 μmol/L, P < .05). These data demonstrate that Sal B inhibits TGF-β1-induced cell proliferation and differentiation in vitro experiment.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Salvia miltiorrhiza (SM, also known as Danshen) is a well-known Chinese medicinal herb, which has shown hepatoprotective effects with anti-fibrotic, anti-oxidative, anti-inflammatory and anti-apoptotic properties. To explore the effects and potential mechanism of SM against hepatic fibrosis induced by chronic iron overload in mice. MATERIALS AND METHODS Sixty male mice were randomized into five groups (n=12 in each group): control (saline), iron overload, iron overload with low-dose SM (3g/kg/day), iron overload with high-dose SM (6g/kg/day) and iron overload with deferoxamine (100mg/kg/day) groups. The iron overload model was established by intraperitoneal injection with iron dextran at 50mg/kg body weight/day, and the entire course lasted for 7 weeks. The major constituents of SM injection were quantified by high performance liquid chromatography. Changes of hepatic iron, hydroxyproline (Hyp), glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MDA) were assayed by standard procedures. Protein expression levels of type I collagen, type III collagen, tumor necrosis factor-α (TNF-α) and interleukin-1α (IL-1α) were analyzed by immunohistochemistry, and mRNA levels of transforming growth factor-β (TGF-β), matrix metal proteinase-9 (MMP-9) and caspase-3 were detected by RT-PCR. Morphological changes were observed with Prussian blue, Masson's trichrome and hematoxylin-eosin staining. RESULTS Treatment of chronic iron-overloaded mice with SM dose-dependently ameliorated changes in hepatic morphology and coefficient, reduced iron deposition and Hyp content, suppressed overexpression of type I collagen and type III collagen, downregulated expression of TGF-β mRNA, and upregulated expression of MMP-9 mRNA in the liver. Moreover, SM treatment contributed to decreased MDA content, increased SOD activity and GSH content, while it reduced expression of TNF-α, IL-1α and caspase-3. CONCLUSIONS SM displayed anti-fibrotic activity in the liver induced by chronic iron overload, which may be attributed to multitargeted inhibition of iron deposition and collagen accumulation, as well as oxidative stress, inflammation and apoptosis.

Abstract
Salvia miltiorrhiza Bunge (Lamiaceae) root, generally called Danshen, is an important herb in Chinese medicine widely used for treatment of various diseases. Phenolic acids in S. miltiorrhiza, as important effective compounds, have become a new research focus in plant secondary metabolism in recent years. This review summarizes the recent advances in the regulation of water-soluble phenolic acid biosynthesis in S. miltiorrhiza via regulators at molecular level, such as the phenylalanine ammonia-lyase gene (PAL), cinnamic acid 4-hydroxylase gene (C4H), 4-coumarate-CoA ligase gene (4CL), tyrosine aminotransferase gene (TAT), 4-hydroxyphenylpyruvate reductase gene (HPPR), 4-hydroxyphenylpyruvated dioxygenase gene (HPPD), hydroxycinnamoyl-CoA:hydroxyphenyllactate hydroxycinnamoyl transferase-like gene (RAS-like), and v-myb avian myeloblastosis viral oncogene homolog 4 gene (MYB4), and production of anthocyanin pigmentation 1 gene (AtPAP1), and via regulators at cell level, such as methyl jasmonate, salicylic acid, abscisic acid, polyamines, metal ions, hydrogen peroxide (H₂O₂), ultraviolet-B radiation, and yeast elicitor.

Abstract
Magnesium lithospermate B (MLB) is one of the major active components of Salvia miltiorrhizae. The anti-oxidative effects of Salvia miltiorrhizae have been previously reported. The aim of this study was to investigate the effect of purified MLB on hepatic fibrosis in rats and on the fibrogenic responses in hepatic stellate cells (HSCs). Hepatic fibrosis was induced in rats by intraperitoneal thioacetamide (TAA) injections over a period of 8 or 12 weeks. MLB was orally administered daily by gavage tube. Serum AST and ALT levels in TAA+ MLB group were significantly lower than those in TAA only group at week 8. Hepatic fibrosis was significantly attenuated in TAA+MLB group than in TAA only group at week 8 or 12. Activation of HSCs was also decreased in TAA+MLB group as compared to TAA only group. Hepatic mRNA expression of α-smooth muscle actin (α-SMA), TGF-β1, and collagen α1(I) was significantly decreased in TAA+MLB group as compared to TAA only group. Incubation with HSCs and MLB (>or=100 μM) for up to 48 h showed no cytotoxicity. MLB suppressed PDGF-induced HSC proliferation. MLB inhibited NF-ΚB transcriptional activation and monocyte chemotactic protein 1 (MCP-1) production in HSCs. MLB strongly suppressed H(2)O(2)-induced reactive oxygen species (ROS) generation in HSCs, and MLB inhibited type I collagen secretion in HSCs. We concluded that MLB has potent antifibrotic effect in TAA-treated cirrhotic rats, and inhibits fibrogenic responses in HSCs. These data suggest that MLB has potential as a novel therapy for hepatic fibrosis.

Abstract
Polysaccharide-rich Lycium barbarum and Rehmannia glutinosa have been considered to have immune-modulating activity. This study investigated the effects of water extracted Lycium barbarum and Rehmannia glutinosa (HE) on carbon tetrachloride ( CCl4)-induced liver injury in rats. Male Sprague-Dawley rats were randomly divided into: normal diet + peritoneal injection of olive oil (control), normal diet + CCl4injection ( CCl4), 1 × HE (0.05% HE for each) + CCl4(1 × HE), and 3 × HE (0.15% HE for each) + CCl4(3 × HE) groups. Rats were injected with 40% CCl4at a dose of 0.75 ml/kg body weight once a week for seven weeks, one week after herbal extract treatment. After eight week herbal extract treatment, pathohistological examination showed that both 1× and 3 × HE treatments diminished necrotic hepatocytes, chemoattraction of inflammatory cells, and liver fibrosis. Both 1× and 3 × HE treatments decreased plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, and reduced hepatic levels of pro-inflammatory cytokines — tumor necrosis factor-α and interleukin-1β — compared to CCl4treatment alone. The 1 × HE treatment increased hepatic anti-inflammatory cytokine IL-10 levels. Both the 1× and 3 × HE treatments suppressed liver fibrosis biomarkers — transforming growth factor-β1 and hydroxyproline. Therefore, treatment with water extracted Lycium barbarum and Rehmannia glutinosa (0.05% and 0.15% for each) for eight weeks protects against necrotic damage, indicated by decreases in plasma ALT and AST activities, and suppresses liver fibrosis by down-regulation of liver inflammation in rats with CCl4-induced liver injury.

Abstract
Abstract
Objectives
The effects of the aqueous extract of Salvia miltiorrhiza Bunge (Danshen) on metabolism/pharmacokinetics of caffeine and on liver microsomal CYP1A2 activity in humans and rats have been investigated.
Methods
The effects of Danshen aqueous extract on CYP1A2 activity were determined by metabolism of model substrates in the rat in vivo and in humans and rats in vitro. HPLC was used to determine model substrates and metabolites.
Key findings
In the rat, single dose Danshen aqueous extract treatment (100 or 200 mg/kg, i.p.) decreased metabolism of caffeine to paraxanthine, with overall decrease in caffeine clearance (6–20%), increase in area under the curve (AUC; 7–24%) and plasma half-life (t½ 14–16%). Fourteen-day Danshen aqueous extract treatment (100 mg/kg/day, i.p. or 200 mg/kg/day, p.o.) decreased caffeine clearance (16–26%), increased AUC (18–31%) and prolonged plasma t½ (8–10%). Aqueous extract of Danshen (125–2000 µg/ml) competitively inhibited human and rat liver microsomal CYP1A2 activity with inhibition constant (Ki) values at 190 and 360 µg/ml, respectively.
Conclusions
These studies demonstrated that Danshen aqueous extract affected the metabolism of CYP1A2 substrates through competitive inhibition and altered their clearance.

Abstract
Salvia miltiorrhiza is traditionally used to treat liver disease in Asia. In this study, we tested the ability of a purified extract of S. miltiorrhiza (PF2401-SF) and its constituents, tanshinone I, tanshinone IIA, and cryptotanshinone, to protect against acute and subacute liver damage induced by carbon tetrachloride by measuring serum transaminase levels, the reduced form of glutathione (GSH), antioxidant enzyme activities, and lipid peroxidation levels in the liver. We also evaluated their ability to protect primary cultured rat hepatocytes from tertiary-butylhydroperoxide (tBH) or d-galactosamine (GalN). PF2401-SF was protective at 50-200mg/kg per day in acute liver injury and 25-100mg/kg per day in subacute liver injury. Tanshinone I, tanshinone IIA, and cryptotanshinon (40 microM), inhibited lactate dehydrogenase leakage, GSH depletion, lipid peroxidation and free radical generation in vitro. PF2401-SF and its major constituents, tanshinone I, tanshinone IIA and cryptotanshinone, can protect against liver toxicity in vivo and in vitro due to its antioxidant effects.

Abstract
Curcumin and saikosaponin a, the bioactive phytochemicals of turmeric and Bupleurum, act as antioxidants. This study investigated the effects of supplementation with curcumin and/or saikosaponin a on hepatic lipids and antioxidant status in rats with CCl(4)-induced liver injury. Male Sprague-Dawley rats were randomly divided into control, CCl(4), CCl(4) + curcumin (0.005%; CU), CCl(4) + saikosaponin a (0.004%; SS), and CCl(4) + curcumin + saikosaponin a (0.005% + 0.004%; CU+SS) groups. CCl(4) (40% in olive oil) was injected intraperitoneally at a dose of 0.75 mL/kg once a week. Curcumin and/or saikosaponin a was administered orally 1 week before CCl(4) injection for 8 weeks. The pathological results showed that liver fibrosis was ameliorated in the SS and CU+SS groups. After 8 weeks, supplementation with curcumin and/or saikosaponin a significantly decreased plasma alanine aminotransferase and aspartate aminotransferase activities, as well as plasma and hepatic cholesterol and triglyceride levels. The CU+SS group showed reversal of the impaired hepatic superoxide dismutase activity and an increase in total glutathione level. Supplementation with curcumin and/or saikosaponin a significantly improved hepatic antioxidant status and suppressed malondialdehyde formation. Therefore, supplementation with curcumin and/or saikosaponin a protects against CCl(4)-induced liver injury by attenuating hepatic lipids and lipid peroxidation and enhancing antioxidant defense. Curcumin and saikosaponin a had no additive effects on hepatoprotection except for greater improvement in the total glutathione level and antioxidant status.

Abstract
Previous studies showed that Compound Astragalus and Salvia miltiorrhiza Extract (CASE) has a protective effect against liver fibrosis. We hypothesized that CASE exerts the anti-fibrosis effect by mediating transforming growth factor-beta (TGF-beta)/Smad signaling pathway. To test this hypothesis, we induced fibrosis in rats by twice weekly injections of carbon tetrachloride (CCl(4)) and Smad2 phosphorylation was measured by immunohistochemical method; protein expression in myofibroblasts (MFBs) induced by TGF-beta1 was analyzed by western blotting and plasminogen activator inhibitor type 1 (PAI-1) transcriptional activity in MFBs was evaluated. The present study showed that, in vivo, CASE has protective effects against liver fibrosis in rats generated by CCl(4), and that CASE inhibits Smad2 phosphorylation at C-terminal region and expression of alpha-smooth muscle actin (alpha-SMA). Our experiment further demonstrated that, in vitro, (1) CASE inhibits TGF-beta(1)-dependent Smad2 phosphorylation at C-terminal region and Smad2 and Smad3 phosphorylation at linker region in MFBs in a dose-dependent manner; (2) CASE decreases the level of Smad 2/3/4 complex in MFBs induced by TGF-beta(1) in a dose-dependent manner; (3) CASE inhibits PAI-1 transcriptional activity in MFBs induced by TGF-beta(1) in a dose-dependent manner; and (4) CASE markedly decreases c-Jun N-terminal kinase (JNK) phosphorylation in MFBs induced by TGF-beta(1). Our results suggest that CASE's anti-fibrosis effect in chronically injured liver was exerted by inhibiting TGF-beta/Smads signal transduction.

Abstract
Liver fibrosis has been characterized as chronic inflammatory processes involving multiple molecular pathogenetic pathways. This therapeutic study investigated whether a combination regimen of Salvia miltiorrhiza (S), Ligusticum chuanxiong (L) and Glycyrrhiza glabra (G) exerted in vivo antifibrotic effects on rats with hepatic fibrosis. Fibrosis was induced in rats by dimethylnitrosamine (DMN) administration for 4 weeks. Fibrotic rats were randomly assigned to one of the three groups: control, SLG (50 mg/kg) or silymarin (50 mg/kg), each given by gavage twice daily for 3 weeks starting 1 week after DMN injection. The results showed that fibrosis scores of livers from DMN-treated rats with SLG (1.13 +/- 0.13) were significantly reduced in comparison with DMN-treated rats receiving vehicle (1.63 +/- 0.18). Moreover, the hepatic collagen content of DMN rats was significantly reduced by either SLG or silymarin treatment. The double immunohistochemical staining results also showed that alpha-SMA positive cells with NF kappa B nuclear translocation were decreased in the fibrotic livers by SLG and silymarin treatments. The mRNA expression levels of TGF-beta1, alpha-SMA, collagen1 alpha 2, iNOS and ICAM-1 genes were attenuated by SLG and silymarin treatment. The results showed that SLG exerted antifibrotic effects in rats with DMN-induced hepatic fibrosis.

Abstract
Tetrandrine (Tet) (C38H42O8N2; molecular weight, 622), an alkaloid isolated from the Chinese medicinal herb Stephania tetrandra, has been shown to elicit anti-inflammatory and anti-fibrotic effects in pulmonary diseases, but the mechanism of action has yet to be investigated. In this study, we tested whether Tet exerts anti-fibrotic effects on rat hepatic fibrosis through anti-NFkappaB pathways. After bile-duct ligation, rats were given Tet (1 or 5 mg/kg) or silymarin (50 mg/kg, as a positive control) by gavage twice daily for 3 weeks. Liver sections were taken for Sirius red quantitative scoring, immunofluorescence double staining of alpha-smooth muscle actin (alpha-SMA) and NFkappaB, and for quantitative determinations of the mRNA expression levels of TGF-beta1, alpha-SMA, collagen 1alpha2, inducible nitric oxide synthase (iNOS), intercellular adhesion molecule 1 (ICAM-1), metallothionein, vascular endothelial growth factor (VEGF), and VEGF type II receptor (VEGFR2) genes. The results showed that both Tet and silymarin treatment significantly reduced the fibrosis scores and hepatic collagen content of BDL rats, compared with no treatment. Both Tet and silymarin treatments decreased the number of alpha-SMA- and NFkappaB-positive cells in fibrotic livers. Moreover, Tet and silymarin treatments attenuated the mRNA expression levels of TGF-beta1,alpha-SMA, collagen 1alpha2, iNOS, ICAM-1, VEGF, and VEGFR2 genes, and induced the mRNA expression of the metallothionein gene. This study suggests that the anti-fibrotic effects of Tet were related to the reduction of fibrosis-related gene transcription, the attenuation of NFkappaB-activated pathways, and the induction of metallothionein gene transcription in the livers of BDL rats.

Abstract
AIM: To investigate the therapeutic effect of tetrandrine on liver fibrosis induced by thioacetamide in rats in vivo and in vitro.
METHODS: In vitro study: we investigated the effect of tetrandrine on the apoptosis of rat hepatic stellate cells transformed by simian virus 40 (T-HSC/Cl-6), which retains the features of activated cells. In vivo study: hepatic fibrosis was induced in rats by thioacetamide. Tetrandrine was given orally to rats at doses of 5, 10 or 20 mg/kg for 4 wk compared with intraperitoneal injection of interferon-г.
RESULTS: In vitro study: 5, 10 or 25 μg/mL of tetrandrine-induced activation of caspase-3 in t-HSC/Cl-6 cells occurred dose-dependently. In vivo study: tetrandrine treatment as well as interferon-г significantly ameliorated the development of fibrosis as determined by lowered serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (T-Bil) and the levels of liver hydroxyproline (Hyp), hyaluronic acid (HA), laminin (LN) and also improved histological findings. The effects of tetrandrine at the concentration of 20 mg/kg were better than the other concentration groups.
CONCLUSION: Tetrandrine promotes the apoptosis of activated HSCs in vitro. Tetrandrine administration can prevent liver fibrosis and liver damage induced by thioacetamide in rats in vivo, indicating that it might exert a direct effect on rat HSCs.

Abstract
BACKGROUND Anti-inflammation strategies are one of the proposed therapeutic approaches to hepatic fibrosis. Tetrandrine (C(38)H(42)O(8)N(2), molecular weight: 622; Tet), an alkaloid isolated from the Chinese medicinal herb Stephania tetrandra, has been shown to exert anti-inflammatory activity in pulmonary diseases. The purpose of the present study was to investigate the in vitro and in vivo effects of Tet on hepatic fibrosis. METHODS A cell line of rat hepatic stellate cells (HSC-T6) was stimulated with transforming growth factor-beta1 (TGF-beta1) or tumor necrosis factor-alpha (TNF-alpha). The inhibitory effects of Tet on the nuclear factor kappaB (NFkappaB) signaling cascade and molecular markers including intercellular adhesion molecule-1 (ICAM-1) and alpha-smooth muscle actin (alpha-SMA) secretion were assessed. Fibrosis was induced by dimethylnitrosamine (DMN) administration in rats for 4 weeks. Fibrotic rats were randomly assigned to one of the four groups: vehicle (0.7% carboxyl methyl cellulose, CMC), Tet (1 mg/kg), Tet (5 mg/kg), or silymarin (50 mg/kg), each given by gavage twice daily for 3 weeks starting after 1 week of DMN administration. At the end of the study, liver tissues were scored for fibrosis and analyzed for molecular markers of fibrosis. RESULTS Tetrandrine (0.5-5.0 micromol/L) concentration-dependently inhibited NFkappaB transcriptional activity induced by TNF-alpha, including IkappaBalpha phosphorylation and mRNA expressions of ICAM-1 in HSC-T6 cells. In addition, Tet also inhibited TGF-beta1-induced alpha-SMA secretion and collagen deposition in HSC-T6 cells. Fibrosis scores of livers from DMN-treated rats with high-dose Tet (1.3 +/- 0.3) were significantly reduced in comparison with DMN-treated rats receiving saline (2.0 +/- 0.2). Hepatic collagen content of DMN rats was significantly reduced by either Tet or silymarin treatment. Double-staining results showed that alpha-SMA- and NFkappaB-positive cells were decreased in the fibrotic livers by Tet and silymarin treatment. In addition, mRNA expression of ICAM-1, alpha-SMA, and TGF-beta1 was attenuated by Tet treatment. Moreover, levels of plasma aspartate aminotransferase and alanine aminotransferase activities were reduced by Tet and silymarin treatment. CONCLUSION Tetrandrine exerts antifibrotic effects in both HSC-T6 cells and in rats with DMN-induced fibrosis.

Abstract
Apoptosis is one of the events that are involved in liver fibrogenesis. Thus, factors that affect apoptosis may be used to modulate liver fibrosis. We have recently reported that Salvia miltiorrhiza plays a protective role in carbon tetrachloride (CCl4)-induced hepatic fibrosis. In this study, we aimed to evaluate whether S. miltiorrhiza modulated CCl4-induced hepatic apoptosis in rats. Male Wistar rats were given orally either vehicle or water-extract of S. miltiorrhiza (50 mg kg(-1) twice daily) for nine weeks beginning from the start of CCl4 administration. A group of normal rats was included for comparison. Hepatocyte DNA fragmentation and cytosolic caspase-3 and caspase-8 activity were determined in the experimental animals. Hepatic cytosolic Bax, Bcl-2, cytochrome c, and calpain-mu expressions were measured by Western blot analysis. Hepatic mitochondrial glutathione levels were assessed by colorimetric assay. Compared with normal rats, rats receiving CCl4 alone showed profound DNA fragmentation associated with an increased cytosolic fraction of cytochrome c and calpain-mu protein expressions and a decreased mitochondrial glutathione level. In contrast, a decreased laddering of DNA fragmentation was noted in rats receiving CCl4 plus S. miltiorrhiza extract. The mitochondrial glutathione level was significantly increased in rats receiving CCl4 plus S. miltiorrhiza extract compared with those receiving CCl4 alone. Additionally, cytosolic caspase-3 activity and cytosolic fractions of Bax, Bcl-2, cytochrome c, and calpain-mu protein expressions were decreased in rats receiving CCl4 plus S. miltiorrhiza extract compared with those receiving CCl4 alone. The cytosolic caspase-8 activity in rats receiving CCl4 alone was no different from those receiving CCl4 plus S. miltiorrhiza extract. These results indicated that chronic administration of S. miltiorrhiza ameliorated CCl4-mediatd hepatic apoptosis in rats. This effect may be related to the antioxidant properties of S. miltiorrhiza.

Abstract
The herbal medicine Salvia miltiorrhiza (Danshen) is currently used for the treatment of cardiovascular and cerebrovascular diseases. To assess possible herb-drug interactions, the effects of the aqueous and ethyl acetate extracts of S. miltiorrhiza on cytochrome P450 (CYP) were studied. Oral treatment of C57BL/6J mice with the ethyl acetate extract caused a dose-dependent increase in liver microsomal 7-methoxyresorufin O-demethylation (MROD) activity. The ethyl acetate extract caused an 8-, 2-, 3- and 3-fold increase in hepatic MROD, tolbutamide hydroxylation, nifedipine oxidation and warfarin 7-hydroxylation activity, respectively. However, the aqueous extract had no effects on any of the activities determined. Pharmaceutical product of S. miltiorrhiza extract caused a dose-dependent increase in MROD activity without affecting other activity. Immunoblot analysis of microsomal proteins showed that ethyl acetate extract-treatment elevated the protein levels of CYP1A and CYP3A. Tanshinone IIA was the main diterpene quinone in S. miltiorrhiza. At the dose corresponding to its content in ethyl acetate extract, tanshinone IIA-treatment increased mouse liver microsomal MROD activity. These results demonstrated that there were mouse CYP1A, CYP2C and CYP3A-inducing agents present in the ethyl acetate extract, but not in the aqueous extract, of S. miltiorrhiza. Tanshinone IIA played a role in the induction of CYP1A by S. miltiorrhiza. The CYP induction by the ethyl acetate extract and pharmaceutical product suggested that possible drug interactions between S. miltiorrhiza and CYP substrates should be noticed.

Abstract
The production of reactive oxygen species (ROS) is believed to be involved in liver injury and hepatic fibrosis. Activation of hepatic stellate cells (HSCs) is a key feature of liver fibrosis. Salvia miltiorrhiza is a traditional Chinese herb used in the treatment of cardiovascular and liver diseases to resolve stasis. The effects of salvianolic acid B (Sal B), a major component of Salvia miltiorrhiza, on oxidative damage include free radical DPPH scavenging, malondialdehyde (MDA) formation and ROS generation in primary rat hepatocytes and HSCs, and on alpha-SMA, and collagen expression in transforming growth factor-beta1 (TGF-beta1)-stimulated HSCs were examined. Results indicated that Sal B scavenged DPPH potently with an IC50 2.2+/-0.2 microg/ml (3.06+/-0.3 microM), inhibited lipid peroxidation and eliminated ROS accumulation in a concentration-dependent manner on primary rat hepatocytes and HSCs. Sal B also reduced alpha-SMA and collagen synthesis and deposition in HSCs, and had no direct cytotoxicity on both hepatocytes and HSCs. Our results suggest that Sal B ameliorated oxidative damage and eliminated ROS accumulation in hepatocytes, and attenuated HSC activation, potentially conferring hepatoprotective and anti-fibrogenic effects.

Abstract
AIM: To observe the effect of protocatechuic aldehyde on the proliferation of hepatic stellate cells (HSCs).
METHODS: Liver fibrosis was induced in rats by carbon tetrachloride (CCl4). Then normal and fibrotic drug sera were extracted from rats. The effects of protocatechuic aldehyde, raw Radix Salvia miltiorrhiza and drug sera of Salvia miltiorrhiza on HSC growth were determined by CCK-8. The protocatechuic aldehyde was separated by high performance liquid chromatography (HPLC) in a Alltima C18 column (250 mm × 4.6 mm, 5 μm) with a mobile phase of acetonitrile-4% glacial acetic acid solution (gradient elution) at the wavelength of 281 nm.
RESULTS: Protocatechuic aldehyde, raw Radix Salvia miltiorrhiza and drug sera of Salvia miltiorrhiza were found to have inhibitory effects on proliferation of rat HSCs. Raw Radix Salvia miltiorrhiza had a stronger inhibitory effect than the drug sera. The fibrotic drug sera showed a higher suppressive effect than the normal drug sera (P < 0.05). Protocatechuic aldehyde was found in crude materials of both Radix Salvia miltiorrhiza and its corresponding drug sera. The average recovery (n = 6) was 110.5% for raw Salvia miltiorrhiza Bge, 102% for normal drug sera and 105.2% for fibrotic drug sera. The relative standard deviation (RSD) was 0.37%, 1.96% and 1.51%, respectively (n = 6). The contents of protocatechuic aldehyde were 0.22%, 0.15% and 0.19%, respectively (n = 6) (P < 0.05). The RSD was 0.33%, 0.75% and 1.24% (n = 6) for raw material of Radix Salvia miltiorrhiza, normal drug sera and fibrotic drug sera, respectively. The samples were stable for 6 d.
CONCLUSION: Protocatechuic aldehyde can inhibit the growth of HSCs. HPLC is suitable for the determination of virtual bioactive components of Chinese herbal medicines in vitro.

Abstract
The qualitative analysis of tanshinones in the roots of Salvia miltiorrhiza (Dan-shen in Chinese) was performed using high-performance liquid chromatography with electrospray ionization tandem mass spectrometry (ESI-MS(n)). Tanshinones are the major bioactive constituents of Dan-shen, which is used in China for the treatment of haematological abnormalities and cardiovascular diseases. The ESI-MS(n) fragmentation behavior of tanshinones was investigated. For tanshinones with the tanshinone I nucleus, the fragmentation was triggered by loss of a molecule of CO except bearing a substituent at C17 or C18, followed by sequential eliminations of CO. If C(15-16) was a saturated bond, the fragmentation was triggered by elimination of a molecule of H2O. For tanshinones with the tanshinone IIA nucleus, the fragmentation was triggered by loss of a molecule of H2O, followed by successive eliminations of CO. Ions corresponding to loss of a molecule of propylene (Delta m = 42) were also observed. Moreover, when C(15-16) was a saturated bond, ions corresponding to losses of CH3, H2O and propylene were more abundant. If no D-ring existed, the presence of isopropyl resulted in an elimination of a molecule of H2O with an adjacent CO or OH. In addition, the extension of the pi-conjugation in the A-ring (especially at C(1-2)) induced the fragmentation by loss of a molecule of CO. These fragmentation rules were applied to the identification of tanshinones in a chloroform/methanol (3:7) extract of Dan-shen, which was separated on a C18 column with gradient elution. A total of 27 tanshinones were identified, including five new constituents. The established method could be used for the sensitive and rapid identification of tanshinones in the Dan-shen drug and its pharmaceutical preparations.

Abstract
Excessive oxidative stress is implicated in hepatic fibrogenesis. Extracts of Salvia miltiorrhiza (Sm) have been shown to protect cells against oxidative stress. In this study we investigated the in vitro and in vivo effects of Sm on hepatic fibrosis. A cell line of rat hepatic stellate cells (HSC-T6) was stimulated with transforming growth factor-beta1 (TGF-beta1). The inhibitory effects of Sm (50-400 microg/ml) on TGF-beta1-induced alpha-smooth muscle actin (alpha-SMA) secretion and the mRNA expressions of fibrosis-related genes, including alpha-SMA, connective tissue growth factor (CTGF), and tissue inhibitor of metalloproteinase-1 (TIMP-1), were assessed. Fibrosis was induced by dimethylnitrosamine (DMN) administration in rats. DMN-treated rats were randomly assigned to 1 of 4 groups: saline, Sm (20 mg/kg), Sm (100 mg/kg), or silymarin (100 mg/kg), each given by gavage twice daily for 5 weeks starting from the onset of DMN administration. Sm (200 and 400 microg/ml) significantly inhibited TGF-beta1-stimulated alpha-SMA secretion and the mRNA expressions of alpha-SMA, CTGF, and TIMP-1 in HSC-T6 cells. Fibrosis scores of livers from DMN-treated rats with either a low (1.8 +/- 0.2) or high (1.8 +/- 0.1) dose of Sm, or silymarin (1.4 +/- 0.2) were significantly reduced in comparison with DMN-treated rats receiving saline (3.1 +/- 0.1). Hepatic collagen contents were also significantly reduced by either Sm or silymarin treatment. The mRNA expression levels of alpha-SMA, TGF-beta1, and procollagen I were all attenuated in Sm- and silymarin-treated rats. Moreover, levels of plasma aspartate transaminase activities were reduced by Sm and silymarin treatment. In conclusion, our results show that Sm exerted antifibrotic effects in both HSC-T6 cells and in rats with DMN-induced fibrosis.

Abstract
AIM: To examine the effects of traditional Chinese medicine (TCM) on alcohol-induced fatty liver in rats. TCM consists of Astragalus membranaceus, Morus alba, Crataegus pinnatifida, Alisma orientale, Salvia miltiorrhiza, and Pueraria lobata.
METHODS: The rats were separated randomly into five groups. One (the CD group) was fed a control diet for 10 wk, another (the ED group) fed an ethanol-containing isocaloric liquid diet for 10 wk, and the last three (the TCM group) were fed an ethanol-containing isocaloric liquid diet for 10 wk and dosed orally with TCM (222 mg/kg•d, TCM222; 667 mg/kg•d, TCM667; and 2 000 mg/kg•d, TCM2000, respectively) weekly during the last 4 wk.
RESULTS: ED group developed fatty liver according to lipid profile and liver histological findings. Compared with the control group, liver/body weight, serum triglyceride (TG) and total cholesterol (TC), liver TG and TC, serum alanine aminotransferase (ALT) and aspartic aminotran-sferase (AST) significantly increased in the ED group. Whereas, in the rats administered with TCM, liver/body weight, serum TG and TC, liver TG and TC, serum ALT and AST were significantly decreased, and the degree of hepatic lipid droplets was markedly improved compared with those in the ED group.
CONCLUSION: TCM treatment causes significant reduction in alcohol-induced lipid hepatic accumulation, reversing fatty liver and liver damage, and can be used as a remedy for alcoholic fatty liver.

Abstract
Salvianolic acid B is an herbal ingredient isolated from Salvia miltiorrhiza. An in vivo microdialysis sampling method coupled to high-performance liquid chromatography has been developed for continuous monitoring of protein-unbound salvianolic acid B in rat blood and bile. Microdialysis probes were inserted into the jugular vein/right atrium and bile duct of Sprague-Dawley rats, and a dose of 100 mg/kg salvianolic acid B was then administered via the femoral vein. Dialysates were collected and directly injected into a liquid chromatographic system. Salvianolic acid B was eluted using a microbore reversed-phase ODS 5 microm (150 mm x 1 mm I.D.) column. Isocratic elution of salvianolic acid B was achieved within 10 min using the liquid chromatographic system. The chromatographic mobile phase consisted of acetonitrile-methanol-20 mM monosodium phosphoric acid (pH 3.5) (10:30:60, v/v/v) containing 0.1 mM 1-octanesulfonic acid with 0.05 ml/min. The wavelength of the UV detector was set at 290 nm. Salvianolic acid B in both blood and bile dialysates was adequately determined using the liquid chromatographic conditions described, although the blank bile pattern was more complex. The retention times of salvianolic acid B in rat blood and bile dialysates were found to be 7.2 min. Peak-areas of salvianolic acid B were linear (r2 > 0.995) over a concentration range of 0.1-50 microg/ml. In vivo recoveries of microdialysis probes of salvianolic acid B in rat blood and bile averaged 22 +/- 2% and 41 +/- 1%, respectively. This study indicates that salvianolic acid B undergoes hepatobiliary excretion.

Abstract
AIM: To make drug sera of Salvia miltiorrhiza and Yigankang, both of which are Chinese herbs that activate bleeding and eliminate stasis, in normal rats and those with liver fibrosis, respectively. To investigate and compare the effects of the two different drug sera on the proliferation and activation of hepatic stellate cells (HSCs).
METHODS: Some rats were induced with liver fibrosis: 40% carbon tetrachloride (CCl4) subcutaneous injection, twice a week for 9 wk. Salvia miltiorrhiza, Yigankang, colchicines and normal saline were administered into the stomachs of normal rats and those with liver fibrosis. Drug sera were extracted 5 d later. HSCs in vitro were cultivated in different drug sera for 24 h. The rates of proliferation and expression of α-smooth muscle actin (α-SMA) were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and immunocyt-ochemistry stain, respectively.
RESULTS: The drug sera from normal and liver fibrotic rats could be used to cultivate HSCs and to observe the effects of the corresponding components of herbs on HSCs. Salvia miltiorrhiza and Yigankang had better inhibitory effects on HSCs than colchicines (MTT: normal drug serum: Salvia miltiorrhiza 0.42±0.08, Yigankang 0.32±0.10 vs colchicines 0.45±0.12 pathological drug serum: Salvia miltiorrhiza 0.33±0.02, Yigankang 0.26±0.01 vs colchicines 0.41±0.09. P<0.05). The drug sera of Salvia miltiorrhiza, Yigankang from liver fibrotic rats had a stronger inhibitory effect than the same ones from normal rats (MTT: Salvia miltiorrhiza: normal drug serum 0.42±0.08 vs pathological drug serum 0.33±0.02. Yigankang: normal drug serum 0.32±0.10 vs pathological drug serum 0.26±0.01. P<0.05).
CONCLUSION: Salvia miltiorrhiza and Yigankang could inhibit the expression of α-SMA and the proliferation of HSCs. The drug sera from normal and liver fibrotic rats had different effects on HSCs, probably due to different metabolic processes, effective components and different quantities of drug contents in drug sera from rats with different states of liver.

Abstract
As an anti-metabolite, Azathioprine inhibits the de novo and salvage pathways of purine synthesis. Intraperitoneal injection of this drug results in not only lymphocyte suppression but also toxicity to bone marrow, gastrointestinal tract, and liver. This Azathioprine-induced hepatotoxicity was found to be associated with oxidative damage. Plants with antioxidative properties have been traditionally used to prevent diseases associated with free radicals. In this report, we used water extracts of three herbal plants that have been commonly used for treating many illnesses (Hibiscus sabdariffa, Rosmarinus officinalis and Salvia officinalis). Here we show their novel hepatoprotective effects against Azathioprine-induced hepatotoxicity in rats. Typically, administration of Azathioprine induces oxidative stress through depleting the activities of antioxidants and elevating the level of malonialdehyde in liver. This escalates levels of alanine aminotransferase, and aspartate aminotranferase in serum. Pretreatment with any of the three herbal plants used in this investigation proved to have a protective effect against Azathioprine-induced hepatotoxicity. Animals pretreated with water extracts from any of the three herbs under investigation not only failed to show necrosis of the liver after azathioprine administration, but also retained livers that, for the most part, were histologically normal. In addition, these herbs blocked the induced elevated levels of alanine aminotransferase and aspartate aminotranferase in serum. The Azathioprine-induced oxidative stress was relieved to varying degrees by the examined herbal extracts. This effect was evident through reducing malonialdehyde levels and releasing the inhibitory effect of Azathioprine on the activities of glutathione, catalase and superoxide dismutase. To our knowledge, this report is the first that shows hepatoprotective effects of Hibiscus, Rosmarinus and Salvia species against Azathioprine-induced acute liver damage.

Abstract
The induction of oxidative stress precedes liver injury during experimental obstructive jaundice (OJ). In this sense, different evidences suggest that melatonin (MEL), as antioxidant, may be useful in the protection against apoptosis and necrosis during experimental cholestasis. In addition, we will also assess if MEL-dependent protection is related to a recovery of antioxidant status disturbances induced by OJ. Cholestasis was achieved by double ligature and sectioning of the principal bile duct. MEL was injected intraperitoneally (500 microg/kg/day). Lipid peroxidation was evaluated by the measurement of malondialdehyde (MDA) content in liver. Different parameters related to antioxidant status, such as reduced glutathione (GSH), glutathione peroxidase (GPx), catalase and superoxide dismutase (SOD) were determined in liver. Liver injury was assessed by alanine amino-transferase (ALT) in serum, histological examination, DNA fragmentation and TUNEL assay. The activation of perisinusoidal stellate cells was evaluated by immunohistochemical measurement of alpha-smooth muscle actin in liver sections. The induction of OJ increased all the parameters related to apoptosis and necrosis in liver. The induction of liver injury was associated with stellate cell activation, as well as an increase in MDA (p < 0.0001) and a reduction in GSH, GPx, catalase and SOD content (p < 0.0001) in liver. MEL reduced hepatic apoptosis and necrosis (p < 0.004) with a significant improvement in all oxidative stress markers. In conclusion, our results showed that MEL recovered the antioxidant status and reduced apoptosis and necrosis induced by experimental cholestasis.

Abstract
We report the effects of Traditional Chinese Medicine (TCM) on alcohol-induced fatty liver in rats. TCM consists of Astragalus membranaceus, Morus alba, Crataegus pinnatifida, Alisma oriental, Salvia miltiorrhiza and Pueraria lobata. The rats were separated randomly into five groups; the CD group (n=10), which was fed a control diet for 10 weeks, the ED group (n=10), which was fed an isocaloric liquid diet containing ethanol for 10 weeks and given daily oral doses of TCM (0.222 g/kg/day; TCM222, 0.667 g/kg/day; TCM667, and 2.000 g/kg/day; TCM2000, n=10, respectively) over the last four weeks of the study. The ED group developed fatty livers, as determined by their lipid profiles and liver histological findings. Compared with the control group, liver/body weight, plasma triglyceride (TG) and total cholesterol (TC), liver TG and TC, plasma alanine aminotransferase (ALT) and aspartic aminotransferase (AST) significantly increased in the ED group. Also, free fatty acids (FFA) levels increased in both plasma and liver during the administration of ethanol. On the other hand, when rats were administrated with TCM, their liver/body weight, plasma TG, TC and FFA, liver TG, TC and FFA, plasma ALT and AST decreased significantly and the degree of hepatic lipid droplets was markedly improved compared with those in the ED group. Proper function of the peroxisome proliferator-activated receptor alpha (PPARalpha) is essential for the regulation of hepatic fatty acid metabolism. Microsomal triglyceride transfer protein (MTP) is essential for the secretion of triglycerides from the liver. mRNAs for PPARalpha and MTP were reduced in the livers of ethanol-fed rats. TCM restored the mRNA levels of PPARalpha and MTP, and prevented development of fatty livers in ethanol-fed rats. Impairment of PPARalpha and MTP function during ethanol consumption contributes to the development of alcohol-induced fatty liver, which can be overcome by TCM.

Abstract
The preventive effect of Salvia miltiorrhiza extracts (SMEs) on the progress of bone loss induced by ovariectomy (OVX) was studied in rats. We measured body weight and bone histomorphometry in sham, OVX or SMEs-administered OVX rats. From light microscopic analyses, a porous or erosive appearances were observed on the surface of trabecular bone of tibia in OVX rats, whereas those of the same bone in sham rats and in SMEs-administered rats were composed of fine particles. The trabecular bone area and trabecular thickness in OVX rats decreased by 50% from those in sham rats, these decreases were completely inhibited by administration of SMEs for 7 weeks. In this study, the mechanical strength in femur neck was significantly enhanced by the treatment of SMEs for 7 weeks. In OVX rats, free T3 was normal in all cases, whereas free T4 was significantly increased. Although there was no difference between OVX and SMEs-administered rats in T3 level, we have found significant difference between them in T4 level. These results strongly suggest that SMEs are effective in preventing the development of bone loss induced by OVX in rats.
