Abstract
Glycyrrhizic acid and its primary metabolite glycyrrhetinic acid, are the main active ingredients in the licorice roots (glycyrrhiza species), which are widely used in several countries of the world, especially in east asian countries (China, Japan). These ingredients and their derivatives play an important role in treating many diseases, especially infectious diseases such as COVID-19 and hepatic infections. This review aims to summarize the different ways of synthesising the amide derivatives of glycyrrhizic acid and the main ways to synthesize the glycyrrhitinic acid derivatives. Also, to determine the main biological and pharmacological activity for these compounds from the previous studies to provide essential data to researchers for future studies.

Abstract
Cancer, a major world public health problem, is associated with chemotherapy treatments whose administration leads to secondary concerns, such as oral mucositis (OM). The OM disorder is characterized by the presence of ulcers in the oral mucosa that cause pain, bleeding, and difficulty in ingesting fluids and solids, or speaking. Bioactive compounds from natural sources have arisen as an effective approach for OM. This review aims to summarize the new potential application of different natural products in the prevention and treatment of OM in comparison to conventional ones, also providing a deep insight into the most recent clinical studies. Natural products, such as Aloe vera, Glycyrrhiza glabra, Camellia sinensis, Calendula officinalis, or honeybee crops, constitute examples of sources of bioactive compounds with pharmacological interest due to their well-reported activities (e.g., antimicrobial, antiviral, anti-inflammatory, analgesic, or wound healing). These activities are associated with the bioactive compounds present in their matrix (such as flavonoids), which are associated with in vivo biological activities and minimal or absent toxicity. Finally, encapsulation has arisen as a future opportunity to preserve the chemical stability and the drug bioa vailability of bioactive compounds and, most importantly, to improve the buccal retention period and the therapeutic effects.

Abstract
Gene and nucleic medicines have recently gained attention as novel drugs with the advancement of molecular biology and genetics; however, they have low bioavailability and low target delivery due to their low stability and poor membrane permeability. Therefore, the development of an effective drug delivery system (DDS) is necessary for the practical use of gene and nucleic acid medicines; however, despite considerable research, both safety and efficiency remain poor. Furthermore, the healthcare needs are not met by traditional DDS. Therefore, we developed an effective multi-functional DDS, which is constructed using materials that are safe for human consumption. This DDS involves several ternary complexes as novel gene delivery carriers constructed by coating the cationic complex of the gene and nucleic acid medicines as well as the biodegradable cationic polymer with a biocompatible anionic polymer. Early implementation of the ternary complex in clinical studies is expected due to their efficacy and safety. Furthermore, these complexes may be prepared using large-scale manufacturing. In addition, personalized DDS may be prepared according to the patient's disease stage, which is useful for advanced therapy.

Abstract
Licorice extract is a Chinese herbal medication most often used as a demulcent or elixir. The extract usually consists of many components but the key ingredients are glycyrrhizic (GL) and glycyrrhetinic acid (GA). GL and GA function as potent antioxidants, anti-inflammatory, antiviral, antitumor agents, and immuneregulators. GL and GA have potent activities against hepatitis A, B, and C viruses, human immunodeficiency virus type 1, vesicular stomatitis virus, herpes simplex virus, influenza A, severe acute respiratory syndrome-related coronavirus, respiratory syncytial virus, vaccinia virus, and arboviruses. Also, GA was observed to be of therapeutic valve in human enterovirus 71, which was recognized as the utmost regular virus responsible for hand, foot, and mouth disease. The anti-inflammatory mechanism of GL and GA is realized via cytokines like interferon-γ, tumor necrotizing factor-α, interleukin- (IL-) 1β, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, and IL-17. They also modulate anti-inflammatory mechanisms like intercellular cell adhesion molecule 1 and P-selectin, enzymes like inducible nitric oxide synthase (iNOS), and transcription factors such as nuclear factor-kappa B, signal transducer and activator of transcription- (STAT-) 3, and STAT-6. Furthermore, DCs treated with GL were capable of influencing T-cell differentiation toward Th1 subset. Moreover, GA is capable of blocking prostaglandin-E2 synthesis via blockade of cyclooxygenase- (COX-) 2 resulting in concurrent augmentation nitric oxide production through the enhancement of iNOS2 mRNA secretion in Leishmania-infected macrophages. GA is capable of inhibiting toll-like receptors as well as high-mobility group box 1.

Cardioprotective Effect of Monoammonium Glycyrrhizinate Injection Against Myocardial Ischemic Injury in vivo and in vitro: Involvement of Inhibiting Oxidative Stress and Regulating Ca 2+ Homeostasis by L-Type Calcium Channels. DRUG DESIGN DEVELOPMENT AND THERAPY 2020; 14:331-346. [PMID: 32158189 PMCID: PMC6986180 DOI: 10.2147/dddt.s232130] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Accepted: 01/15/2020] [Indexed: 01/15/2023]
Abstract
Purpose Monoammonium glycyrrhizinate (MAG) is an aglycone of glycyrrhizin that is found in licorice and is often used clinically as an injection to treat liver diseases. However, the effect of MAG injection on cardiac function and its possible cellular mechanisms remain unclear. We explored the protective effects of MAG against myocardial ischemic injury (MII) induced by isoproterenol (ISO), as well as the cellular mechanisms via molecular biology techniques and patch-clamp recording. Methods A rat model of myocardial ischemia injury was induced by administering ISO (85 mg/kg) subcutaneously for 2 consecutive days. ECG, cardiac functional parameters, CK and LDH levels, SOD and GSH activities, MDA concentration, histological myocardium inspection, mitochondria ultrastructure changes, intracellular calcium concentrations were observed. Influences of MAG on ICa-L and contraction in isolated rat myocytes were observed by the patch-clamp technique. Results MAG reduced damage, improved cardiac morphology, inhibited oxidative stress, decreased the generation of reactive oxygen species, and decreased intracellular Ca2+ concentration. Exposure of the rats’ ventricular myocytes to MAG resulted in a concentration-dependent reduction in L-type calcium currents (ICa-L). MAG reduced ICa-L in a consistent and time-dependent fashion with a semi-maximal prohibitive concentration of MAG of 14 μM. MAG also shifted the I-V curve of ICa-L upwards and moved the activation and inactivation curves of ICa-L to the left. Conclusion The findings indicate that MAG injection exerts a protective influence on ISO-induced MII by inhibiting oxidative stress and regulating Ca2+ homeostasis by ICa-L.

Abstract
The present study aimed to investigate the potential anti-inflammatory and anti-nociceptive activities of glycyrrhizin (GL) in mice and to explore the possible related mechanisms. Xylene-induced ear edema, carrageenan-induced paw edema and acetic acid-induced vascular permeability test were used to investigate the anti-inflammatory activities of GL in mice. Anti-nociceptive effects of GL were assessed by using acetic acid-induced writhing, hot plate test and formalin test, as well as evaluation of spontaneous locomotor activity and motor performance. The mRNA expression of pro-inflammatory cytokines (such as TNF-α, IL-6 and iNOS) and the protein expression of cyclooxygenase-2 (COX-2) were explored by using real-time fluorogenic PCR and Western blot, respectively. The results showed that GL significantly reduced xylene-induced ear edema, carrageenan-induced paw edema, and acetic acid-induced vascular permeation. Additionally, GL significantly inhibited the nociceptions induced by acetic acid and formalin. However, the nociceptions could not be decreased by GL in the hot plate test, and GL did not affect spontaneous locomotor activity and motor performance. The expression levels of TNF-α, IL-6, iNOS and COX-2 were significantly downregulated by GL. In conclusion, GL exerts significant anti-inflammatory and analgesic activities by attenuating the expression levels of TNF-α, IL-6, iNOS and COX-2.

Abstract
The study was conducted to investigate the potential of liquorice extract (LE) from Glycyrrhiza uralensis as a dietary supplement for sheep to improve antioxidant capacity of meat. Fifty Tan sheep were randomly allocated to five groups with LE supplementation at levels of 0, 1000, 2000, 3000 and 4000 mg/kg feed. After 120 days, the longissimus thoracis muscle was sampled and conditioned for 0, 2, 4, 6 and 8 days at 4 °C. The results revealed that LE scavenged free radical in a dose-response manner in vitro. Supplementation with LE in animal diet increased (P<0.05) antioxidant content and radical scavenging activity while it decreased (P<0.05) reactive oxygen species (ROS) and thiobarbituric acid reactive substance (TBARS) levels of meat. Dietary LE supplementation can improve antioxidant capacity of meat, and the optimum dosage range of LE supplementation appeared to be 3000 to 4000 mg/kg feed.

Abstract
HMGB1 is a nuclear component involved in nucleosome stabilization and transcription regulation, but extracellularly it is able to serve as a potential late mediator of lethality. In the present study, we explored inflammation-promoting activity of HMGB1 and blockade of extracellular release of HMGB1 by glycyrrhizin (GL) in LPS/GalN-triggered mouse liver injury. At 1 to 10 h after LPS/GalN-treatment, mice were anesthetized to collect blood from heart puncture, and serum transaminase and HMGB1 were evaluated. Administration of LPS/GalN precipitated tissue injury associated with time-dependent alteration in HMGB1 serum levels. At 8 h nuclear immunoreactive products were remarkably reduced and extracellular HMGB1 expression was found exclusively in the pericentral foci. The treatment with GL significantly down-regulated the serum levels of ALT, AST, and HMGB1 in addition to the strong inhibition of tissue injury and extracellular immunoreactivity to HMGB1 and to acetylated-lysine. Furthermore, GL brought about a significant decrease in the number of apoptotic hepatocytes labeled with TUNEL-method. On the basis of these results, three apoptosis-associated genes were identified with microarray analysis and real-time PCR. The ChIP-assay revealed the binding of HMGB1 protein to Gsto1 promoter sequence in LPS/GalN-treated mice and the remarkable decrease in combined HMGB1 protein by GL. The current findings claim that a single injection of LPS/GalN might stimulate apoptosis of hepatocytes through the binding of HMGB1 protein to Gsto1 promoter region and that GL-treatment might prevent the apoptosis and inflammatory infiltrates caused with LPS/GalN-injection by disturbing the binding of HMGB1 protein to Gsto1 promoter sequence.

Abstract
The present study is aiming at evaluating the hepatoprotective and antioxidant effects of Glycyrrhiza glabra extract (2.5, 5 and 10 μg/ml) on the carbon tetrachloride (CCl(4))-induced carp hepatocyte damage in vitro. Glycyrrhiza glabra extract was added to the carp primary hepatocytes before (pre-treatment), after (post-treatment) and both before and after (pre- and post-treatment) the incubation of the hepatocytes with CCl(4). CCl(4) at 8 mM in the culture medium produced significantly elevated levels of lactate dehydrogenase (LDH), glutamate oxalate transaminase (GOT), glutamate pyruvate transaminase (GPT) and malondialdehyde (MDA) and significantly reduced levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Pre-treatment (5 μg/ml) and pre- and post-treatment (5 and 10 μg/ml) of the hepatocytes with Glycyrrhiza glabra extract significantly reduced the elevated levels of LDH, GOT, GPT and MDA and increased the reduced levels of SOD and GSH-Px by CCl(4); post-treatment of the hepatocytes with Glycyrrhiza glabra extract at 5 μg/ml reduced the GPT and GOT levels and increased the GSH-Px level, but had no effect on the other parameters at all the studied concentrations. The results support the use of Glycyrrhiza glabra extract as a hepatoprotective and antioxidant agent in fish.

MATERIALS AND METHODS The ITS2 regions of 114 samples in Fabaceae were amplified. Sequence assembly was assembled by CodonCode Aligner V3.0. In combination with sequences from public database, the sequences were aligned by Clustal W, and genetic distances were computed using MEGA V4.0. The intra- vs. inter-specific variations were assessed by six metrics, wilcoxon two-sample tests and "barcoding gaps". Species identification was accomplished using TaxonGAP V2.4, BLAST1 and the nearest distance method. RESULTS ITS2 sequences had considerable variation at the genus and species level. The intra-specific divergence ranged from 0% to 14.4%, with an average of 1.7%, and the inter-specific divergence ranged from 0% to 63.0%, with an average of 8.6%. Twenty-four species found in the Chinese Pharmacopoeia, along with another 66 species including their adulterants, were successfully identified based on ITS2 sequences. In addition, ITS2 worked well, with over 80.0% of species and 100% of genera being correctly differentiated for the 1507 sequences derived from 1126 species belonging to 196 genera. CONCLUSIONS Our findings support the notion that ITS2 can be used as an efficient and powerful marker and a potential barcode to distinguish various species in Fabaceae.

Abstract
OBJECTIVE AND DESIGN In this study, the possible protective effect of glycyrrhizin (GL), an active compound derived from licorice root, was examined on T cell-mediated liver injury in mice. MATERIALS AND METHODS Mice were subjected to liver injury by intravenous injection of concanavalin A (Con A). They had been treated with GL (i.p.) 30 min before the injection. Liver injury was estimated by measuring serum levels of alanine aminotransaminase (ALT) and aspartate aminotransaminase (AST), and by examining liver sections with hematoxylin-eosin staining. Expression of inducible nitric oxide synthase (iNOS) mRNA and protein in the liver was determined by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting. RESULTS Serum transaminases and hepatic iNOS levels increased with time after Con A treatment. Expression of iNOS mRNA in the liver was elevated for up to 8 h, and at 8 h, GL (ED(50): 10.5 mg/kg) suppressed the increases in AST and ALT in response to Con A. An increase in iNOS mRNA expression and protein was inhibited by treatment with GL. Furthermore, GL inhibited cell infiltration and the degeneration of hepatocytes in the liver of Con A-treated mice. CONCLUSION The present study suggests that the prevention by GL of Con A-induced hepatitis is due partly to the modulation of hepatic iNOS induction and of degeneration of hepatocytes.

Abstract
The inhibition of apoptosis by glycyrrhizin (GL) in hepatic injury induced by injection of lipopolysaccharide (LPS)/D-galactosamine (D-GalN) was examined in the present study. Morphological and biochemical analyses of LPS/D-GalN-induced mouse liver injury revealed that apoptosis occurred exclusively in injured hepatocytes of the centrilobular area. The degree of hepatic injury was associated with a substantial number of hepatocytes undergoing apoptosis. Transaminase levels were significantly increased at 6 to 8 h after the injection of LPS/D-GalN compared with controls. GL inhibited the elevation of serum transaminase levels when it was given to mice at 30 min before the administration of LPS/D-GalN. Morphological analyses using the TUNEL-method showed GL significantly reduced the number of TUNEL-labeled cells in acute hepatitis induced with LPS/D-GalN-treatment. Cells from the pericentral hepatic injury region were dissected out using a microdissection-method, and the DNA-ladder was clearly documented. Furthermore, results obtained through the TUNEL-method were confirmed with an oligonucleosome-bound DNA ELISA. From the current results, it seems reasonable to conclude that the protective role of GL in LPS/D-GalN-induced liver injury is performed through the inhibition of hepatic apoptosis.

Abstract
Massive hepatectomy associated with infection induces liver dysfunction, or even multiple organ failure and death. Glycyrrhizin has been shown to exhibit anti-oxidant and anti-inflammatory activities. The aim of the present study was to investigate whether glycyrrhizin could attenuate endotoxin-induced acute liver injury after partial hepatectomy. Male Wistar rats (6 to 8 weeks old, weighing 200-250 g) were randomly assigned to three groups of 24 rats each: sham, saline and glycyrrhizin. Rats were injected intravenously with lipopolysaccharide (LPS) 24 h after 70% hepatectomy. Glycyrrhizin, pre-administered three times with 24 h intervals 48 h before hepatectomy, prolonged the survival of rats submitted to partial hepatectomy and LPS injection, compared with saline controls. Glycyrrhizin was shown to attenuate histological hepatic changes and significantly reduced serum levels of aspartate aminotransferase, alanine aminotransferase, and lactic dehydrogenase, at all the indicated times (6 rats from each were sacrificed 1, 3, 6, and 9 h after LPS injection), compared with saline controls. Glycyrrhizin also significantly inhibited hepatocyte apoptosis by down-regulating the expression of caspase-3 and inhibiting the release of cytochrome C from mitochondria into the cytoplasm. The anti-inflammatory activity of glycyrrhizin may rely on the inhibition of release of tumor necrosis factor-a, myeloperoxidase activity, and translocation of nuclear factor-kappa B into the nuclei. Glycyrrhizin also up-regulated the expression of proliferating cell nuclear antigen, implying that it might be able to promote regeneration of livers harmed by LPS. In summary, glycyrrhizin may represent a potent drug protecting the liver against endotoxin-induced injury, especially after massive hepatectomy.

Abstract
Glycyrrhizin, a biological active compound isolated from the liquorice root, has been used as a treatment for chronic hepatitis. We have examined the involvement of matrix metalloproteinase (MMP)‐9 in the development of lipopolysaccharide (LPS) and D‐galactosamine (GalN)‐induced liver injury in mice. We also investigated the effect of glycyrrhizin on expression of MMP‐9 in this model. Levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) increased after LPS/GalN treatment. Expression of MMP‐9 mRNA and protein was markedly up‐regulated in liver tissues 6–8 h after LPS/GalN treatment. Pretreatment with glycyrrhizin (50 mg kg−1) and the MMP inhibitor (5 mg kg−1) suppressed increases in serum levels of ALT and AST in mice treated with LPS/GalN. Furthermore, glycyrrhizin inhibited levels of both mRNA and protein for MMP‐9. Immunohistochemical reaction for MMP‐9 was observed in macrophages/monocytes infiltrated in the inflammatory area of liver injury. Glycyrrhizin reduced the infiltration of inflammatory cells and immunoreactive MMP‐9 in liver injury. The results indicated that MMP‐9 played a role in the development of LPS/GalN‐induced mouse liver injury, and suggested that an inhibition by glycyrrhizin of the acute liver injury may have been due to a down‐regulation of MMP‐9.

Abstract
Glycyrrhizin is the major active component extracted from licorice (Glycyrrhiza glabra) roots, one of the most widely used herbal preparations for the treatment of liver disorders. This study evaluated the potential beneficial effect of glycyrrhizin in a mouse model of carbon tetrachloride (CCl(4))-induced liver injury. The mice were treated intraperitoneally with CCl(4) (0.5 ml/kg). They received glycyrrhizin (50, 100, 200, 400 mg/kg) 24 h and 0.5 h before and 4 h after administering CCl(4). The serum activities of aminotransferase and the hepatic level of malondialdehyde were significantly higher 24 h after the CCl(4) treatment, while the concentration of reduced glutathione was lower. These changes were attenuated by glycyrrhizin. CCl(4) increased the level of circulating tumor necrosis factor-alpha markedly, which was reduced by glycyrrhizin. The levels of hepatic inducible nitric oxide synthase, cyclooxygenase-2, and heme oxygenase-1 protein expression were markedly higher after the CCl(4) treatment. Glycyrrhizin diminished these alterations for inducible nitric oxide and cyclooxygenase-2 but the protein expression of heme oxygenase-1 was further elevated by the treatment of glycyrrhizin. CCl(4) increased the level of tumor necrosis factor-alpha, inducible nitric oxide synthase, cyclooxygenase-2, and heme oxygenase-1 mRNA expressions. The mRNA expression of heme oxygenase-1 was augmented by the glycyrrhizin treatment, while glycyrrhizin attenuated the increase in tumor necrosis factor-alpha, inducible nitric oxide synthase, and cyclooxygenase-2 mRNA expressions. These results suggest that glycyrrhizin alleviates CCl(4)-induced liver injury, and this protection is likely due to the induction of heme oxygenase-1 and the downregulation of proinflammatory mediators.

Abstract
The effects of glycyrrhizin isolated from licorice root were investigated on acute hepatitis induced by lipopolysaccharide (LPS) and d-galactosamine in mice. Serum alanine aminotransferase (ALT) activity was markedly increased 6 h to 8 h after administration of LPS/d-galactosamine. Levels in serum of cytokines such as tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, IL-10 and IL-12 reached a maximum by 2 h, whereas levels of IL-18, as well as of ALT, were maximal at 8 h. Glycyrrhizin (ED(50): 14.3 mg/kg) inhibited the increase in ALT levels when it was given to mice at 30 min before administration of LPS/d-galactosamine. Inflammatory responses, including infiltration of neutrophils and macrophages in the liver injury, were modulated by glycyrrhizin. Increases in ALT levels were reduced by an administration of glycyrrhizin at 10 min and 60 min but not 3 h, even after LPS/d-galactosamine treatment. However, glycyrrhizin had no effect on the production of TNF-alpha, IL-6, IL-10 and IL-12, whereas it significantly inhibited IL-18 production. Exogenous IL-18 further increased the elevation in ALT levels in mice treated with LPS/d-galactosamine. Glycyrrhizin completely suppressed the effect of IL-18 of increasing ALT levels. IL-18 was detected by immunohistochemistry in inflammatory cells such neutrophils and macrophages in liver injury. Glycyrrhizin reduced the responsiveness of cells to IL-18 in the liver injury. These results suggest that glycyrrhizin inhibits the LPS/d-galactosamine-induced liver injury through preventing inflammatory responses and IL-18 production. Furthermore, it seems that glycyrrhizin prevents IL-18-mediated inflammation in liver injury.

Abstract
Almost all patients with liver disease, especially advanced liver disease, have some evidence of malnutrition, including mineral/vitamin deficiency. A major health trend in the United States has been the significant growth in the use of complementary and alternative medicine (CAM), including nutrition supplements and herbal agents. In the 1990s, the United States government created the National Center for Complementary and Alternative Medicine (NCCAM), as well as the Office on Dietary Supplements, to extend our knowledge in these areas. CAM users are often highly educated and frequently use CAM therapy for chronic diseases, including chronic liver disease. Indeed, most studies suggest that patients with chronic liver disease frequently use nutrition supplements and CAM agents in addition to their traditional medicines. The purpose of this review is to provide an update on the role of nutrition supplements and herbals in liver disease. This article will focus mainly on 7 selected agents (vitamin E, zinc, magnesium, S-adenosylmethionine, betaine, silymarin, and glycyrrhizin), for which there have been not only in vitro and animal studies but also human clinical trials, and we will review both potential efficacy and safety issues.

Abstract
OBJECTIVE Patients with chronic hepatitis C who do not respond to interferon can be treated with glycyrrhizin to reduce disease activity. The objective of this study was to evaluate the effect of glycyrrhizin on the incidence of hepatocellular carcinoma (HCC) during long-term follow-up after non-response to interferon. MATERIAL AND METHODS We analyzed individual patient data of all consecutive patients treated with interferon in 12 major Japanese hospitals between 1990 and 1995 who showed no sustained response. RESULTS The study comprised 1093 patients. During a mean follow-up of 6.1 +/- 1.8 years, 107 patients developed HCC. The Cox regression analysis with time-dependent variables showed that older age, male gender, higher alanine aminotransferase (ALAT) and higher fibrosis stage were significantly associated with a higher risk of developing HCC. Response to glycyrrhizin, defined as ALAT < 1.5 x upper limit of normal, was significantly associated with a decreased incidence of HCC: hazard ratio 0.39 (95% CI 0.21-0.72; p < 0.01). G-estimation, used to correct for ALAT as the confounder, showed no significant benefit of glycyrrhizin in the overall study population. CONCLUSIONS This study provides some evidence to show that interferon non-responder patients with chronic hepatitis C and fibrosis stage 3 or 4 may have a reduced incidence of HCC if glycyrrhizin therapy leads to normalization of ALAT levels.

Abstract
The Fas/FasL signalling system plays an important role in chemotherapy-induced apoptosis in several different cell types. After interferon-gamma (IFN-gamma) treatment, we have previously reported a significant increase in Fas expression in oral malignant melanoma cell lines (MMN9, PMP, MAA, HMG) in vitro, and combination therapy using IFN-gamma and anti-Fas antibody (CH-11) has shown a synergistic anti-proliferative effect in MMN9 cells. There have been several in-vitro studies using CH-11, but there are few reports of its anti-tumour effect in vivo. In this study, we investigated experimental therapy using anti-Fas antibody against MMN9 in vivo in a mouse model, and histologically examined tumour tissue removed from BALB/c nude mice. Animals that received both IFN-gamma and CH-11 showed a 53.8% increase in anti-tumour effect (P=0.0018) 20 days after the first administration. In the histological study, the combined administration group tested positive in terminal deoxynucleotidyl transferase-mediated nick end labelling staining, and showed significantly increased levels of Fas expression on immunostaining compared with the vehicle group. These results show the efficacy of anticancer therapy using IFN-gamma and anti-Fas antibody via the modulation of Fas-mediated apoptosis. Moreover, inhibition of IFN-gamma/CH-11-induced apoptosis with a general caspase inhibitor (benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone) reduced cell death significantly in vitro. Bcl-2 cleavage did not occur under these conditions, suggesting a relationship between caspase activation and Bc1-2 cleavage in MMN9 cells.

Abstract
A suitable carrier chitosan (CS) was used to prepare CS-Glycyrrhetic acid (GLA) nanoparticles under very mild conditions by polyelectrolyte complexation. These nanoparticles were well dispersed and stable in aqueous solution, and the physicochemical properties of which were investigated by FT-IR, dynamic light scattering, transmission electron microscope, fluorescence spectra and zeta potential. It was found that only when the weight ratio of CS to GLA was lower than 16.7, could the nanoparticles be formed. The prepared nanoparticles carried a positive charge and had the dried TEM-assessed size in the range from 20 to 30 nm. The mean hydrated diameter, size distribution and zeta potential of the nanoparticles could be controlled by some factors including the weight ratio of CS to GLA, the average molecular weight of CS and the pH value of the medium. It was also found that GLA encapsulation efficiency into the nanoparticles increased with the increase of the weight ratio of CS to GLA. The experiment of GLA release in vitro showed that the effect of CS encapsulation on GLA release was obvious and the CS-GLA nanoparticles system might be used to provide a continuous release.

Abstract
Within a few minutes of an intravenous injection of a lipopolysaccharide (LPS) into mice, platelets accumulate, largely in the lung. At higher doses, LPS induces rapid shock (within 10 min), leading to death within 1 h. This type of shock differs from so-called endotoxin shock, in which shock signs and death occur several hours or more later. Here, we found that platelet depletion (by a monoclonal anti-platelet antibody) prevented LPS-induced rapid shock, but increased delayed lethality. In Japan, glycyrrhizin (GL), a compound isolated from licorice, is daily and slowly infused intravenously into chronic hepatitis C patients. A single bolus intravenous injection into mice of GL (200 mg/kg or less) shortly before (or simultaneously with) LPS injection reduced the pulmonary platelet accumulation and the severity of the rapid shock, and prevented death in both the early and later periods. GL itself, at 400 mg/kg, produced no detectable abnormalities in the appearance or activity of mice. Intraperitoneal injection of aspirin or dexamethasone had only marginal effects on LPS-induced platelet responses and lethality. These results suggest that platelets play important roles in the development of both the rapid and delayed types of shock induced by LPS. Although the mechanism by which GL suppresses platelet responses and delayed lethality remains to be clarified, GL might provide a strategy for alleviating the acute respiratory distress syndrome seen in sepsis. Our results may also support the proposal by Cinatl et al. [Cinatl J, Morgenstern B, Bauer G, Chandra P, Ravenau H, Doerr HW. Glycyrrhizin, an active component of liquorice roots, and replication of SARS-associated coronavirus. Lancet 2003; 361: 2045–6.] that GL may be an effective drug against severe acute respiratory syndrome.

Abstract
Complementary and alternative medicine (CAM) is presently not considered to be part of conventional medicine. Nevertheless, an estimated 51% of patients with gastrointestinal disorders have tried some from of CAM. Indeed, 10% of alternative medicines are being used for digestive symptoms. After prayer or spiritual healing, herbal medicine is the second most common CAM therapy. While herbal products make numerous health-related claims, those that have been systematically evaluated are unfortunately few. The modern gastroenterologist must be up to date with the regulations, side effects, and possible benefits of specific herbal products used in patients with gastrointestinal disorders.

Abstract
AIM To investigate the influence of picroside II on hepatocyte apoptosis and its mechanism. METHODS Morphological changes and quantification of apoptotic cells were determined under transmission electron microscopy and flow cytometry respectively. DNA fragmentation was visualized by agarose gel electrophoresis. Semi-quantitative reverse transcription-PCR (RT-PCR) was used to analyze the expression of bcl-2 and bax genes. The content of manganese-superoxide dismutase (SOD) in liver mitochondria was detected by the Marland method. The content of malonic aldehyde (MDA) and the protein level in liver tissue were determined by thiobarbituric acid colorimetry and Lowry method. RESULTS Picroside II decreased the levels of alanine aminotransferase and aspartate aminotransferase in the serum resulting from acute-liver injured mice induced with D-GalN and LPS; it also reduced the content of MDA, and thus, enhanced the activity of SOD. Picroside II 10 mg/kg was found to protect hepatocytes against apoptosis in a dose-dependent manner; it up-regulated the expression of bcl-2 genes, thus increased the bcl-2/bax ratio. CONCLUSION Picroside II can protect hepatocytes against injury and prevent hepatocytes from apoptosis. It might by upregulating the bcl-2 gene expression and antioxidation.

Abstract
1. Minocycline has anti-inflammatory and antiapoptotic effects on cartilage, neurons and periodontal tissues, and both properties are central to the pharmaceutical treatment of liver diseases. We investigated the effects of minocycline on fulminant hepatitis in C57BL/6J mice induced by lethal challenge of the activating anti-Fas antibody, Jo2. 2. Intraperitoneal injection of Jo2 (0.6 microg g(-1)) to mice resulted in fulminant hepatitis, as evidenced by increase of serum alanine/aspartate transaminase activities and histopathological alterations in liver sections, as well as animal death. Nevertheless, mice pretreated with three doses of minocycline (5 mg kg(-1)) resisted this lethal effect significantly. Minocycline treatment improved the survival kinetics, although to a lesser extent, when mice were challenged simultaneously with Jo2 or even treated 30 min after the lethal challenge. 3. Jo2-induced activation of caspase-3 or -9 in liver tissues was inhibited by minocycline pretreatment, and yet the direct addition of minocycline to liver extracts from Jo2-challenged mice failed to block caspase activation in vitro. Moreover, minocycline efficiently suppressed the release of cytochrome c from mitochondria of the liver tissues from Jo2-challenged mice. In contrast, caspase-8 activation and Bid truncation triggered by Jo2 were not diminished by minocycline pretreatment in mouse livers. 4. Our results suggest that easing of Fas-triggered fulminant hepatitis by minocycline may involve a mitochondrial apoptotic pathway, probably through preventing cytochrome c release and thereby blocking downstream caspase activation.

Abstract
The interaction between monoammonium glycyrrhizinate (MAG) and bovine serum albumin (BSA) were studied by fluorescence and absorption spectroscopy. The quenching mechanism of fluorescence of bovine serum albumin by monoammonium glycyrrhizinate was discussed. The binding sites number n and apparent binding constant K were measured by fluorescence quenching method. The thermodynamic parameters DeltaH degrees , DeltaG degrees , DeltaS degrees at different temperatures were calculated. The distance r between donor (bovine serum albumin) and acceptor (monoammonium glycyrrhizinate) was obtained according to Forster theory of non-radiation energy transfer. The results of synchronous fluorescence spectra and UV-vis absorption spectra show that the conformation of bovine serum albumin has been changed.

Abstract
M50054, 2,2'-methylenebis (1,3-cyclohexanedione), was identified as a novel inhibitor of apoptosis (programmed cell death) using an in vitro cell death assay system induced in human Fas-expressing WC8 cells by soluble human Fas ligand. Furthermore, M50054 inhibited the apoptotic cell death of U937, a human monocytic leukemic cell line, induced by anticancer agents such as etoposide; it was also confirmed that M50054 inhibited apoptotic features such as DNA fragmentation and phosphatidylserine exposure in these cells. These anti-apoptotic effects were attributable to inhibition of caspase-3 activation. Additionally, M50054 significantly inhibited anti-Fas-antibody-induced elevation of plasma alanine aminotransferase and aspartate aminotransferase. Alopecia (hair loss) symptoms were also significantly improved with topical treatment with M50054. In conclusion, M50054 inhibits apoptosis induced by a variety of stimuli via inhibition of caspase-3 activation, and may thus be effective for hepatitis and chemotherapy-induced alopecia.

Abstract
Interferon (IFN)-based therapy is a standard treatment for chronic hepatitis caused by hepatitis C virus (HCV) infection. This treatment is effective in approximately 30-40% of the patients and using ribavirin in combination with IFN increases the rate of sustained virologic clearance. For the remaining patients, glycyrrhizin is often used. Glycyrrhizin is known to prevent the development of hepatocellular carcinoma (HCC), but glycyrrhizin is usually administered intravenously. Drugs that are effective by oral administration are convenient for patients for long-term administration, and development of more effective drugs than glycyrrhizin is preferable. However, studies on drugs for the treatment of hepatitis are not actively conducted, and promotion of the study of drugs in this area is encouraging. For that reason, we show our approach to study drugs for the treatment of hepatitis. We analyzed the effect of glycyrrhizin on hepatitis as a standard chemical using the mouse liver injury model. Based on this, we screened drugs and found that a coumarin derivative seems to be one of model chemicals for the treatment of hepatitis.

Abstract
Ligation of the Fas receptor (FasR) is a key step in apoptosis induction. Using a series of human tumor cells (SNB19, SNB79, 143N2, and SHEP), we observed a distinct efficacy of human anti-FasR antibody with an apparent correlation with Fas cell surface antigen expression. In contrast, all cells studied expressed detectable FasR mRNA transcripts. For all anti-FasR antibody-sensitive tumor cells, we showed a similar efficacy of Mab according to dose fractionation and injection site. We showed that, when injected into nude mice bearing human osteosarcoma 143N2, neuroblastoma SHEP, prostatic cancer PAC120, and the two glioblastomas SNB19 and SNB79, anti-FasR Mab induces significant inhibition of the growth rate of 143N2, SHEP, and PAC120 tumors, but has no efficacy on SNB19 and SNB79 tumors, with a relationship between in vitro and in vivo sensitivity to anti-FasR antibody. Altogether, these results suggest the antitumor potential of anti-FasR antibody in human neoplasms.

Abstract
The experimental data in recent years suggest apoptosis of liver cells plays a significant role in the pathogenesis of viral hepatitis. Firstly, the number of apoptotic hepatocytes in patients with hepatitis B or C is significantly higher than healthy objects. Secondly, the expression levels of Fas antigen in hepatocytes of patients with hepatitis B or C are closely correlated with inflammation activity. Thirdly, massive apoptosis of hepatocyte will result in fulminant hepatitis, while inhibition of apoptosis can prevent inflammation in experimental model of liver injury. And finally, the occurrence of hepatitis induced by CTL in transgenic mice is a process from hepatocyte apoptosis to liver necroinflammation. This paper will examine our current understanding of the possible relationship between hepatocellular apoptosis and the pathogenetic mechanism of hepatitis B and C.

Abstract
Tumor necrosis factor (TNF)-alpha-induced hepatitis and apoptosis, as respectively assessed by serum enzyme activities and hepatic DNA fragmentation were effectively suppressed by a single force-feeding of caffeine (100 mg/kg) 1.5 h before injecting the drug. In contrast, caffeine had no significant effect on anti-Fas antibody-induced hepatitis and apoptosis. These results suggest that caffeine differentially affected TNF-alpha receptor- and Fas-mediated hepatitis and apoptosis.

Abstract
The effects of coumarin derivatives, osthole, imperatorin, Pd-Ia, Pd-II and Pd-III, on mice concanavalin A (Con A) (0.2 mg/mouse, i.v.)-induced hepatitis were studied. At the dose of 200 mg/kg (i.p.), these coumarins inhibited more than 90% of the Con A-induced elevation of plasma alanine aminotransferase activity, but glycyrrhizin (200 mg/kg, i.p.) caused only 45% inhibition. At the dose of 100 mg/kg (i.p.), osthole produced the strongest inhibition among these coumarins. The inhibitory activity of osthole is lost when its 7-methoxy group is replaced by a 7-hydroxy group to form osthenol. The present results showed that coumarin derivatives inhibited Con A-induced hepatitis, with osthole being the most inhibitory.
