Zhong Y, Li J, Zhu X, Huang N, Liu R, Sun R. A comprehensive review of bupleuri radix and its bioactive components: with a major focus on treating chronic liver diseases. JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118244. [PMID: 38663781 DOI: 10.1016/j.jep.2024.118244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Revised: 04/19/2024] [Accepted: 04/22/2024] [Indexed: 04/30/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bupleuri Radix (BR) has been recognized as an essential herbal medicine for relieving liver depression for thousands of years. Contemporary research has provided compelling evidence of its pharmacological effects, including anti-inflammatory, immunomodulatory, metabolic regulation, and anticancer properties, positioning it as a promising treatment option for various liver diseases. Hepatitis, steatohepatitis, cirrhosis, and liver cancer are among the prevalent and impactful liver diseases worldwide. However, there remains a lack of comprehensive systematic reviews that explore the prescription, bio-active components, and underlying mechanisms of BR in treating liver diseases. AIM OF THE REVIEW To summarize the BR classical Chinese medical prescription and ingredients in treating liver diseases and their mechanisms to inform reference for further development and research. MATERIALS AND METHODS Literature in the last three decades of BR and its classical Chinese medical prescription and ingredients were collated and summarized by searching PubMed, Wiley, Springer, Google Scholar, Web of Science, CNKI, etc. RESULTS: BR and its classical prescriptions, such as Xiao Chai Hu decoction, Da Chai Hu decoction, Si Ni San, and Chai Hu Shu Gan San, have been utilized for centuries as effective therapies for liver diseases, including hepatitis, steatohepatitis, cirrhosis, and liver cancer. BR is a rich source of active ingredients, such as saikosaponins, polysaccharides, flavonoids, sterols, organic acids, and so on. These bioactive compounds exhibit a wide range of beneficial effects, including anti-inflammatory, antioxidant, immunomodulatory, and lipid metabolism regulation. However, it is important to acknowledge that BR and its constituents can also possess hepatotoxicity, which is associated with cytochrome P450 (CYP450) enzymes and oxidative stress. Therefore, caution should be exercised when using BR in therapeutic applications to ensure the safe and appropriate utilization of its potential benefits while minimizing any potential risks. CONCLUSIONS To sum up, BR, its compounds, and its based traditional Chinese medicine are effective in liver diseases through multiple targets, multiple pathways, and multiple effects. Advances in pharmacological and toxicological investigations of BR and its bio-active components in the future will provide further contributions to the discovery of novel therapeutics for liver diseases.

Abstract
Alternative medicines, especially herbal remedies, have been employed to treat infections and metabolism-related chronic inflammation because their safety and multidimensional therapeutic potential outweigh those of synthetic drugs. So Shiho Tang (SSHT), a well-known Oriental prescription (Xiao Chai Hu Tang in Chinese) composed of seven herbs, is traditionally prescribed to treat various viral infections and chronic metabolic disorders in Asia with or without the support of other natural medicines. To provide a general background on how SSHT is used as a medicinal alternative, we conducted a scoping review using the PubMed database system. Among the 453 articles, 76 studies used aqueous extracts of SSHT alone. This result included seven clinical studies and 69 basic studies: cell-based, animal-based, and ex vivo studies. The in vitro and clinical reports mainly focus on hepatic infection and hepatocarcinoma, and the documentation of in vivo tests of SSHT presents a wide range of effects on cancer, fibrosis, inflammation, and several metabolic disorder symptoms. Additionally, among the seven clinical records, two reverse-effect case studies were reported in middle-aged patients. In brief, this systematic review provides general knowledge on the natural remedy SSHT and its potential in phytotherapeutic primary health care.

Abstract
Viruses, the smallest microorganisms, continue to present an escalating threat to human health, being the leading cause of mortality worldwide. Over the decades, although significant progress has been made in the development of therapies and vaccines against viral diseases, the need for effective antiviral interventions remains urgent. This urgency stems from the lack of effective vaccines, the severe side effects associated with current drugs, and the emergence of drug-resistant viral strains. Natural plants, particularly traditionally-used herbs, are often considered an excellent source of medicinal drugs with potent antiviral efficacy, as well as a substantial safety profile. Scutellaria baicalensis, a traditional Chinese medicine, has garnered considerable attention due to its extensive investigation across diverse therapeutic areas and its demonstrated efficacy in both preclinical and clinical trials. In this review, we mainly focused on the potential antiviral activities of ingredients in Scutellaria baicalensis, shedding light on their underlying mechanisms of action and therapeutic applications in the treatment of viral infections.

Abstract
The purpose of this study is to develop and validate an UPLC-MS/MS method to quantify different marker compounds from Xiao-Chai-Hu-Tang (XCHT, a Chinese traditional herbal) in biological samples and apply the method to pharmacokinetic study. A Waters BEH C18 UPLC column was used with acetonitrile/0.1% formic acid mobile phases. The mass analysis was performed in a triple quadrupole mass spectrometer using multiple reaction monitoring (MRM) with positive scan mode. A one-step protein precipitation by methanol was used to extract the analytes from blood. Seventeen commercially available compounds from the different compositing herbals were selected as markers. The results revealed that all of the calibration curves showed good linear regression (r(2)>0.9918). The intra-day and inter-day precisions (RSD) of all of these markers at three different levels were less than 15.0% and the bias of the accuracies ranged from -13.5% to 16.6%.The extraction recoveries of all of these 17 markers were from 70.8% to 113.7% and the matrix effects ranged from 71.8% to 114.8%. The stabilities of these compounds in blood were evaluated by analyzing three replicates of QC samples at three different concentrations following storage at 25°C for 6h, 4°C for 24h, and -80°C for 30 days. All the samples displayed 85-115% precision and accuracy after various stability tests. The validated method was successfully applied to pharmacokinetic study in A/J mouse with oral administration of XCHT. All of these markers were detected and the pharmacokinetic parameters of 8 compounds were able to be calculated. This method is sensitive and reproducible that can be used for XCHT's in vivo study.

Abstract
An herbal medicine (Kampo) is widely used to prevent or treat climacteric symptoms. In order to investigate the potential involvement of tumor necrosis factor (TNF)-α in susceptibility to mood disorder in climacteric women and to clarify the relationship between immune function and the efficacy of herbal medicine, we compared serum TNF-α levels in two treated groups, with and without concurrent use of herbal medicine. This study included 113 consecutive depressed menopausal patients who visited the gynecological and psychosomatic medicine outpatient clinic of the Osaka Medical College Hospital in Japan. Fifty-eight patients were administered Kami-shoyo-san according to the definition of above Sho. In contrast, 55 patients who were different in Sho of Kami-shoyo-san were administered antidepressants. Hamilton Rating Scale for depression (HAM-D) scores were determined at baseline and 12 weeks after starting treatment (endpoint). TNF-α concentrations were analyzed before and after 12 weeks of treatment. Kami-shoyo-san significantly increased plasma concentrations of TNF-α after 12 weeks of treatment, to 17.22 ± 6.13 pg/ml from a baseline level of 14.16 ± 6.27 pg/ml (p = 0.048). The percent change in plasma concentration of TNF-α differed significantly between the Kami-shoyo-san therapy group and the antidepressant therapy group at 4 weeks (12.0 ± 7.8% and -1.22 ± 0.25%, respectively, p <0.01), 8 weeks (19.7 ± 3.4% and -2.45 ± 0.86%, respectively, p <0.01), and 12 weeks (21.3 ± 5.4% and -6.81 ± 2.2%, respectively, p <0.001). We found in this study that Kami-shoyo-san, an herbal medicine, increased plasma TNF-α levels in depressed menopausal patients. Cytokines may play various roles in mood and emotional status via the central nervous system and may be regulated by herbal medicines, although the interactions are very complex.

Renal protective effect of xiao-chai-hu-tang on diabetic nephropathy of type 1-diabetic mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:984024.

Abstract
Xiao-Chai-Hu-Tang (XCHT), a traditional Chinese medicine formula consisting of seven medicinal plants, is used in the treatment of various diseases. We show here that XCHT could protect type-1 diabetic mice against diabetic nephropathy, using streptozotocin (STZ)-induced diabetic mice and high-glucose (HG)-exposed rat mesangial cell (RMC) as models. Following 4 weeks of oral administration with XCHT, renal functions and renal hypertrophy significantly improved in the STZ-diabetic mice, while serum glucose was only moderately reduced compared to vehicle treatment. Treatment with XCHT in the STZ-diabetic mice and HG-exposed RMC resulted in a decrease in expression levels of TGF-β1, fibronectin, and collagen IV, with concomitant increase in BMP-7 expression. Data from DPPH assay, DHE stain, and CM-H2DCFDA analysis indicated that XCHT could scavenge free radicals and inhibit high-glucose-induced ROS in RMCs. Taken together, these results suggest that treatment with XCHT can improve renal functions in STZ-diabetic mice, an effect that is potentially mediated through decreasing oxidative stress and production of TGF-β1, fibronectin, and collagen IV in the kidney during development of diabetic nephropathy. XCHT, therefore merits further investigation for application to improve renal functions in diabetic disorders.

Abstract
The traditional Chinese herbal medicine Sho-saiko-to is a mixture of seven herbal preparations that has long been used in the treatment of chronic liver disease. Various clinical trials have shown that Sho-saiko-to protects against the development of hepatocellular carcinoma in cirrhotic patients. However, the mechanism by which Sho-saiko-to protects hepatocytes against hepatic fibrosis and carcinoma is not yet known. Basic science studies have demonstrated that Sho-saiko-to reduces hepatocyte necrosis and enhances liver function. Sho-saiko-to significantly inhibits hepatic fibrosis by inhibiting the activation of stellate cells, the major producers of collagen in the liver, as well as by inhibiting hepatic lipid peroxidation, promoting matrix degradation, and suppressing extracellular matrix (ECM) accumulation. Furthermore, clinical trials have shown that Sho-saiko-to lowers the rate of hepatocellular carcinoma (HCC) development in patients with cirrhosis and increases the survival of patients with HCC. Unfortunately, some case reports have shown the side effects of Sho-saiko-to. Most of the side effects were interstitial pneumonia and acute respiratory failure induced by Sho-saiko-to in Japan. As a result of analyzing these case reports, the incidence and risk are increased by co-administration of interferon, duration of medication, and, high in an elderly population. This review discusses the properties of Sho-saiko-to with regards to the treatment of chronic liver diseases and suggests the side effects of Sho-saiko-to.

Abstract
Chronic pharyngitis, a chronic inflammation of the pharyngeal mucous membrane and submucous lymphoid tissues, is often caused by unsatisfactory treatment of acute pharyngitis or repeated occurrences of upper respiratory tract infection and is related to a high-dust environment. Traditional herbal pharmacotherapy is well known for combining plant species to create complex phytochemical mixtures in the attempt to ameliorate pathophysiological processes. The aim of current study is to investigate the effect of immunoregulation and anti-inflammation with the traditional Chinese medicine (TCM) "Li-Yan Zhi-Ke Granule" in rats. Determination of serum hemolysin and the carbon particle clearance test were performed. The results demonstrate that administration of the TCM "Li-Yan Zhi-Ke Granule" may improve the effect of phagocytosis by mononuclear macrophages and immune function in rats, and may also increase the immunoregulatory and anti-inflammatory responses of rats with chronic pharyngitis. This traditional drug could relieve the symptoms of sore throat and cough in rats with chronic pharyngitis.

Abstract
Many of the botanical "immunomodulators", a class of herbal medicines widely recognized in traditional medical systems such as Chinese Medicine (TCM) and Ayurvedic Medicine, alter immune function and may offer clinically relevant therapeutics or leads to therapeutics. Many of these traditional remedies are prepared from combinations of medicinal plants which may influence numerous molecular pathways. These effects may differ from the sum of effects from the individual plants and therefore, research demonstrating the effects of the formula is crucial for insights into the effects of traditional remedies. In this review we surveyed the primary literature for research that focused on combinations of medicinal plants and effects on cytokine activity. The results demonstrate that many extracts of herb mixtures have effects on at least one cytokine. The most commonly studies cytokines were IL-4, IL-6, IL-10, TNF and IFN-γ. The majority of the formulas researched derived from TCM. The following formulas had activity on at least three cytokines; Chizukit N, CKBM, Daeganghwal-tang, Food Allergy Formula, Gamcho-Sasim-Tang, Hachimi-jio-gan, Herbkines, Hochuekki, Immune System Formula, Jeo-Dang-Tang, Juzen-taiho-to, Kakkon-to, Kan jang, Mao-Bushi-Saishin-to, MSSM-002, Ninjin-youei-to, PG201, Protec, Qing-huo-bai-du-yin, Qingfu Guanjieshu, Sambucol Active Defense, Seng-fu-tang, Shin-Xiao-Xiang, Tien Hsien, Thuja formula, Unkei-to, Vigconic, Wheeze-relief-formula, Xia-Bai-San, Yangyuk-Sanhwa-Tang, Yi-fey Ruenn-hou, and Yuldahansotang. Of the western based combinations, formulas with Echinacea spp. were common and showed multiple activities. Numerous formulas demonstrated activity on both gene and protein expression. The research demonstrates that the reviewed botanical formulas modulate cytokine activity, although the bulk of the research is in vitro. Therapeutic success using these formulas may be partially due to their effects on cytokines. Further study of phytotherapy on cytokine related diseases/syndromes is necessary.

Abstract
BACKGROUND AND OBJECTIVE Oral epithelial cells help to prevent against bacterial infection in the oral cavity by producing antimicrobial peptides (AMPs). A broad-spectrum AMP, calprotectin (a complex of S100A8 and S100A9 proteins), is expressed by oral epithelial cells and is up-regulated by interleukin-1alpha (IL-1alpha). Shosaikoto (SST) is a traditional Japanese herbal medicine that has immunomodulatory effects and is reported to enhance the levels of IL-1alpha in epithelial cells. The purpose of this study was to investigate the effect of SST on the expression of calprotectin and other AMPs through the regulation of IL-1alpha in oral epithelial cells. MATERIAL AND METHODS Human oral epithelial cells (TR146) were cultured with SST (at concentrations ranging from 10 to 250 microg/mL) in the presence or absence of anti-IL-1alpha or IL-1 receptor antagonist. The expression of S100A8- and S100A9-specific mRNAs was examined by northern blotting. Calprotectin expression and IL-1alpha secretion were investigated by immunofluorescent staining or ELISA. The expression of other AMPs and IL-1alpha was analyzed by RT-PCR and by quantitative real-time PCR. RESULTS Shosaikoto (25 microg/mL) significantly increased the expression of S100A8- and S100A9-specific mRNAs and calprotectin protein. Shosaikoto increased S100A7 expression, but had no effect on the expression of other AMPs. The expression of IL-1alpha-specific mRNA and its protein were slightly increased by SST. A neutralizing antibody against IL-1alpha or IL-1 receptor antagonist inhibited SST up-regulated S100A8/S100A9 mRNA expression. CONCLUSION These results suggest that SST increases the expression of calprotectin and S100A7 in oral epithelial cells. In response to SST, up-regulation of calprotectin may be partially induced via IL-1alpha.

Abstract
AIM Traditional herbal medicines have been used for several thousand years in China and other Asian countries. In this study we screened herbal drugs and their purified compounds, using the Feo replicon system, to determine their effects on in vitro HCV replication. METHODS We screened herbal drugs and their purified extracts for the activities to suppress hepatitis C virus (HCV) replication using an HCV replicon system that expressed chimeric firefly luciferase reporter and neomycin phosphotransferase (Feo) genes. We tested extracts and 13 purified compounds from the following herbs: Glycyrrhizae radix; Rehmanniae radix; Paeoniae radix; Artemisiae capillari spica; and Rhei rhizoma. RESULTS The HCV replication was significantly and dose-dependently suppressed by two purified compounds, isoliquiritigenin and glycycoumarin, which were from Glycyrrhizae radix. Dose-effect analyses showed that 50% effective concentrations were 6.2 +/- 1.0 microg/mL and 15.5 +/- 0.8 microg/mL for isoliquiritigenin and glycycoumarin, respectively. The MTS assay did not show any effect on cell growth and viability at these effective concentrations, indicating that the effects of the two compounds were specific to HCV replication. These two compounds did not affect the HCV IRES-dependent translation nor did they show synergistic action with interferon-alpha. CONCLUSION Two purified herbal extracts, isoliquiritigenin and glycycoumarin, specifically suppressed in vitro HCV replication. Further elucidation of their mechanisms of action and evaluation of in vivo effects and safety might constitute a new anti-HCV therapeutics.

Abstract
Traditional Chinese medicine (TCM) has been used for thousands of years. Most Chinese herbal formulae consist of several herbal components and have been used to treat various diseases. However, the mechanisms of most formulae and the relationship between formulae and their components remain to be elucidated. Here we analyzed the putative mechanism of San-Huang-Xie-Xin-Tang (SHXXT) and defined the relationship between SHXXT and its herbal components by microarray technique. HepG2 cells were treated with SHXXT or its components and the gene expression profiles were analyzed by DNA microarray. Gene set enrichment analysis indicated that SHXXT and its components displayed a unique anti-proliferation pattern via p53 signaling, p53 activated, and DNA damage signaling pathways in HepG2 cells. Network analysis showed that most genes were regulated by one molecule, p53. In addition, hierarchical clustering analysis showed that Rhizoma Coptis shared a similar gene expression profile with SHXXT. These findings may explain why Rhizoma Coptis is the principle herb that exerts the major effect in the herbal formula, SHXXT. Moreover, this is the first report to reveal the relationship between formulae and their herbal components in TCM by microarray and bioinformatics tools.

Abstract
Chronic pancreatitis (CP) is characterized by progressive fibrosis, pain and/or loss of exocrine and endocrine functions. Recent in vitro and in vivo experiments have proven objectively the role of activated pancreatic stellate cells (PSC) in fibrogenesis in CP. Molecular mediators shown to regulate the pathogenesis include transforming growth factor beta (TGF-beta), platelet-derived growth factor (PDGF), and pro-inflammatory cytokines such as IL-1, IL-6 and TNF-alpha. Furthermore, molecular pathways involving mitogen-activated protein kinases (MAPK), phosphatidyl inositol 3-kinase (PI3K), Ras superfamily G proteins, serine threonine protein kinase Raf-1 and peroxisome proliferator activated receptor gamma (PPAR-gamma) have been elucidated. Understanding of the pathogenesis has led to identification of novel molecular targets and development of potential newer therapeutic agents. Those found to retard the progression of experimental CP and fibrosis in animal models include interferon (IFN) beta and IFN-gamma; a Japanese herbal medicine called Saiko-keishi-to (TJ-10); curcumin; PPAR-gamma ligand (troglitazone); antioxidants (vitamin A, vitamin E, DA 9601 and epigallocatechin-3-gallate); a protease inhibitor (camostat mesilate) and hydroxymethylglutaryl-CoA inhibitor (lovastatin). This review summarizes the current literature addressing the role of different pharmacological agents aimed at reducing or preventing inflammation and the consequent fibrogenesis in CP.

Abstract
To search for an effective antiviral agent, this study tested the hypothesis that sho-saiko-to (Xiao-Chai-Hu-Tang) and crude saikosaponins possess the activity directly against HBV and could affect the expressions of viral antigens, HBeAg and HBsAg, in HepG(2) 2.2.15 cell model. The viral amount and viral antigens in the suspension were estimated by quantitative real time PCR and enzyme-linked immunosorbent assay (ELISA), respectively. The results showed that sho-saiko-to could inhibit the production of HBV (p < 0.0001), 20 microg/ml sho-saiko-to was efficacious at day-3 of treatment and 10 microg/ml at day-6. The calculated IC(50) and CC(50) of sho-saiko-to were 55.76 microg/ml and 372 microg/ml, respectively, with a selectivity index of 6.67. Crude saponin of B. chinense could also inhibit the replication of HBV (p < 0.0001). Owing to the anti-neoplastic activity of sho-saiko-to and saikosaponin, their calculated CC(50) and selectivity index might be under-estimated. Sho-saiko-to also decreased the expression of HBeAg with the minimal effective concentration of 20 microg/ml. Sho-saiko-to contained too little saikosaponin. Therefore, the anti-HBV activity of sho-saiko-to might not be mediated by saikosaponin. Sho-saiko-to could be supplementary to nucleotide analogues to minimize the recurrence of viremia after its discontinuation.

Abstract
A literature survey was conducted on herbs, their preparations and ingredients with reported liver protection activities, in which a total of 274 different species and hundreds of active ingredients have been examined. These ingredients can be roughly classified into two categories according to their activities: (1) the main ingredients, such as silybin, osthole, coumarin, glycyrrhizin, saikosaponin A, schisandrin A, flavonoids; and (2) supporting substances, such as sugars, amino acids, resins, tannins and volatile oil. Among them, some active ingredients have hepatoprotective activities (e.g. anti-inflammatory, anticancer, antioxidant, immunomodulating and liver cirrhosis-regulating effects). Calculation of physicochemical parameters indicates that the main ingredients with negative and positive Elumo values possibly display their hepatoprotective effects through different mechanisms, such as antioxidative, anti-inflammatory and immunomodulating effects. As the combination of herbs may achieve some treatment effects synergistically and/or additively, it is common in Chinese medicine to use mixtures of various medicinal herbs with pharmacologically active compounds to have synergistic and/or additive effects, or to reduce harmful effects of some pharmacologically active compounds. In particular, the active compounds with Clog P around 2 are suitable for passive transport across membranes and accessible to the target sites. Thus, Elumo and Clog P values are good indicators among the calculated parameters. Seven different physicochemical parameters (MW, Clog P, CMR, μ, Ehomo, Elumo and Hf) and four major biological activities (antioxidant, anti-inflammatory, antiviral/antitumor and immunomodulating) are discussed in this review. It is hoped that the discussion may provide some leads in the development of new hepatoprotective drugs.

Abstract
Chai-Hu-Ching-Kan-Tang (CHCKT) is one of the traditional Chinese medicine prescriptions commonly used to treat liver diseases. In this study, we evaluated the hepatoprotective effects of aqueous CHCKT extract at various concentrations (125, 250 and 500 mg/kg body weight) on acetaminophen (APAP)-induced acute liver injury in rats. Results showed that CHCKT treatments significantly decreased the level of serum glutamic oxaloacetic transaminase (sGOT) and glutamic pyruvic transaminase (sGPT) in APAP-treated groups. CHCKT also significantly decreased the level of lipid peroxides and increased the activity of antioxidant enzymes (i.e. SOD and GPx). Histopathological observation further confirmed the hepatoprotective activity of CHCKT as indicated by the amelioration in the central necrosis and fatty changes of the liver after APAP induction. Interestingly, the hepatoprotective activity of CHCKT at concentrations 125~500 mg/kg appeared to be as good as 12.5 mg/kg silymarin (a commercial hepatoprotective agent). Taken together, these results suggest that aqueous extract of CHCKT possesses potent hepatoprotective effects agianst APAP-induced liver injury in rats.

Abstract
BACKGROUND/AIMS Chronic pancreatitis is characterized by acinar destruction and fibrosis. We previously reported that apoptosis is involved in acinar destruction in chronic pancreatitis in the WBN/Kob rat. This study aimed to elucidate the antiapoptotic effect of Saikokeishito (TJ-10). METHODS Four-week-old male WBN/Kob rats were fed a special pellet diet (MB-3) with or without TJ-10 (80 mg/100 g body weight) for 20 weeks. Pancreas was histopathologically examined every 4 weeks, and the expression of apoptosis-related factors such as Fas and Fas ligand (FasL) mRNA and protein was analyzed with RT-PCR, in situ hybridization and immunohistochemistry. Apoptosis was detected with a TUNEL method. RESULTS In untreated WBN/Kob rats, chronic pancreatitis developed at 12 weeks and progressed with marked acinar cell destruction at 16 weeks. The expression of Fas and FasL peaked at 12 and 20 weeks. An apoptotic index in acinar cells correlated to the expression of Fas and FasL mRNA. However, in the TJ-10-treated rats, the rate of pancreatic acinar cell destruction, the apoptotic index at 12-20 weeks, and the expression of Fas and FasL at 12 and 20 weeks decreased significantly compared to those in untreated rats. CONCLUSION These results suggest that TJ-10 has a therapeutic effect on chronic pancreatitis by the suppression of acinar cell apoptosis via the Fas/FasL system.

Abstract
Complementary and alternative medicine (CAM) has been used for centuries in China and Japan to treat various illnesses, including viral hepatitis. Several therapeutic approaches constitute CAM, the most relevant for this review being the use of herbals. However, profound disagreements exist between conventional and alternative medicine practitioners regarding their value. Western medical advocates cite deep concerns about the purity of most herbals because of lack of standardized production, the paucity of pharmacokinetic data, the fact that few well-designed randomized, controlled trials of these products have been performed and the evidence that some herbals have been responsible for severe adverse effects. Nevertheless, many in the public, even in western countries, turn to the use of herbals, believing that they must be safe and effective because they are ‘natural’ and have been used for centuries, and because of dissatisfaction with conventional medicine. Accordingly, their use in western countries and the costs incurred have increased each year. While there is evidence that some herbals have physiological effects, there still is insufficient evidence to recommend their use. This paper reviews the classification, epidemiology and philosophy of CAM, and the reasons advanced for herbal use to treat viral hepatitis. The criteria necessary to develop a potential pharmacological agent are presented, as well as the requirements for conducting a scientifically valid treatment trial of herbals. Five herbals used in the past to treat viral hepatitis are reviewed and evaluated for the quality of their studies and mention is made of herbals known to have adverse effects.

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
This study evaluated PYM00217, a proprietary blend of plant extracts, in the management of canine atopic dermatitis (AD). One hundred and twenty dogs were diagnosed with perennial AD on the basis of history, clinical signs, a positive test for perennial allergens and elimination of other dermatoses. Exclusion criteria included antimicrobials within 7 days, antihistamines within 14 days, oral/topical glucocorticoids or ciclosporin within 28 days, and parenteral glucocorticoids, essential fatty acids or immunotherapy within 56 days. Flea control, shampoos and ear cleaners were permitted. Dogs with a minimum canine atopic dermatitis extent and severity index (CADESI) of 25 were randomly allocated to receive PYM00217 (100, 200 or 400 mg kg-1 day-1) or placebo for 12 weeks. The mean reductions in CADESI (intention-to-treat population) were 3.9% (placebo; n=29), 4.4% (100 mg kg-1 day-1; n=30), 23.4% (200 mg kg-1 day-1; n=29) and 8.5% (400 mg kg-1 day-1; n=29). The reduction in the 200 mg kg-1 day-1 group was significant (P<0.01). For dogs with a baseline CADESI>or=50, the mean changes were +10.6% (placebo; n=12), +0.6% (100 mg kg-1 day-1; n=14), -29.3% (200 mg kg-1 day-1; n=14) and -3.4% (400 mg kg-1 day-1; n=15). The 200 mg kg-1 day-1 dose was significantly more effective than placebo (P=0.038). No serious adverse effects were reported. Minor adverse effects seen in 10% (placebo and 100 mg kg-1 day-1), 24% (200 mg kg-1 day-1) and 42% (400 mg kg-1 day-1) of cases were mainly minor gastrointestinal disorders and only five cases required cessation of dosing. Two dogs (one in each of the 100 mg kg-1 day-1 and 200 mg kg-1 day-1 groups) refused to eat the medicated food. In conclusion, PYM00217 at 200 mg kg-1 appears to be an effective, palatable and well-tolerated treatment for canine AD.

Abstract
Chronic pancreatitis (CP) is characterized by progressive fibrosis, pain and/or loss of exocrine and endocrine functions. With the identification and characterization of pancreatic stellate cells (PSCs), the pathogenesis of CP and pancreatic fibrosis is now better understood. Molecular mediators shown to regulate the pathogenesis include transforming growth factor-beta, platelet-derived growth factor, and proinflammatory cytokines such as interleukin (IL)-1, IL-6 and tumor necrosis factor-alpha. Besides these, the roles of cyclooxygenase (COX)-2 and apoptosis-related proteins have also been implicated in the pathogenesis. Furthermore, molecular pathways involving mitogen-activated protein kinases, phosphatidylinositol 3-kinase, Ras superfamily G proteins, serine threonine protein kinase Raf-1 and peroxisome proliferator-activated receptor-gamma (PPAR-gamma) have been elucidated. Newer pathobiologic concepts concerning pain generation have also been put forward. Understanding the pathogenesis has led to the identification of novel molecular targets and the development of newer potential therapeutic agents. Those found to retard the progression of experimental CP and fibrosis in animal models include antioxidants, a Japanese herbal medicine called Saiko-keisi-to (TJ 10), the PPAR-gamma ligand troglitazone, the protease inhibitor Camostat mesilate, and Lovastatin.

Abstract
Coxsackie B virus type 1 (CVB1) infection is known to cause high morbidity and mortality in children, however, there is no effective drug for treating this disease. The present study aimed to examine the antiviral activity of xiao chai hu tang (XCHT), a popular herbal drug for treating viral and bacterial infections, against CVB1 infection and its mechanisms of action. Our data showed that XCHT neutralized the CVB1-induced cytopathic effect in human neonatal foreskin fibroblast cell line (CCFS-1/KMC), with IC50 (virus-induced cytopathic effect by 50%) and EC50 (concentration of 50% effectiveness) values around 12.39 and 50.93 microg/ml, respectively. Its CC50 (concentration of 50% cellular cytotoxicity) and SI (selective index) values were 945.75 microg/ml and 18.92, respectively. These results suggest that XCHT possessed anti-CVB1 activity, and showed no effect on CCFS-1 cell viability and growth at concentration 250 microg/ml. The time-of-addition studies showed that XCHT (50, 100 and 200 microg/ml) added at various time of preinfection (-1 to -3 h), coinfection (0 h) and postinfection (1 approximately 3 h) could inhibit CVB1 infection. Interestingly, XCHT also showed an inhibition on viral replication through the induction of IFN-alpha/beta expression. In conclusion, XCHT possessed antiviral activity against CVB1 infection. It interfered the early stage of viral replication (prophylactic effect) and viral replication after infection (therapeutic effect) through the induction of Type I interferon expression.

Abstract
BACKGROUND The pathogenesis of chronic hepatitis C virus (HCV) infection is associated with a defective host antiviral immune response and intrahepatic oxidative stress. Oxidative stress and lipid peroxidation play major roles in the fatty liver accumulation (steatosis) that leads to necro-inflammation and necrosis of hepatic cells. Previous trials suggested that antioxidative therapy may have a beneficial effect on patients with chronic HCV infection. AIMS To determine the safety and efficacy of treatment of chronic HCV patients via a combination of antioxidants. METHODS Fifty chronic HCV patients were treated orally on a daily basis for 20 weeks with seven antioxidative oral preparations (glycyrrhizin, schisandra, silymarin, ascorbic acid, lipoic acid, L-glutathione, and alpha-tocopherol), along with four different intravenous preparations (glycyrrhizin, ascorbic acid, L-glutathione, B-complex) twice weekly for the first 10 weeks, and followed up for an additional 20 weeks. Patients were monitored for HCV-RNA levels, liver enzymes, and liver histology. Assessment of quality of life was performed using the SF-36 questionnaire. RESULTS In one of the tested parameters (eg, liver enzymes, HCV RNA levels, or liver biopsy score), a combination of antioxidants induced a favorable response in 48% of the patients (24). Normalization of liver enzymes occurred in 44% of patients who had elevated pretreatment ALT levels (15 of 34). ALT levels remained normal throughout follow-up period in 72.7% (8 of 11). A decrease in viral load (one log or more) was observed in 25% of the patients (12). Histologic improvement (2-point reduction in the HAI score) was noted in 36.1% of the patients. The SF-36 score improved in 26 of 45 patients throughout the course of the trial (58% of the patients). Treatment was well tolerated by all patients. No major adverse reactions were noted. CONCLUSIONS These data suggest that multi antioxidative treatment in chronic HCV patients is well tolerated and may have a beneficial effect on necro-inflammatory variables. A combination of antiviral and antioxidative therapies may enhance the overall response rate of these patients.

Abstract
OBJECTIVE In order to develop and search for more effective and safe treatments for early and advanced stages of ovarian cancer, we examined the direct effects of four extracts of Chinese herbal drugs on ovarian cancer cells in vitro. METHODS The growth inhibition of four herbal drugs on a total of six cell lines of human ovarian cancer cells was determined by a Cell Counting Kit-8 by counting viable cells. Apoptotic cells induced by herbal drugs were detected by using MEBCYTO Apoptosis Kit. All experiments were performed in triplicate. The significance of the difference was analyzed with a two-sided Student's t test. A P value less than 0.05 was accepted as statistically significant. RESULTS The MN, A2780, and KF cell lines exhibited significant growth inhibition in the presence of Sho-saiko-to concentrations of 150 microg/ml, 300 microg/ml, and 500 microg/ml, respectively, and at the concentration of 1000 microg/ml, Sho-saiko-to demonstrated a significant apoptotic induction effect on all six kinds of ovarian cancer cell lines. This concentration is the same as the blood concentration attained when 7.5 g of Sho-saiko-to per day is orally administered and all absorbed. CONCLUSIONS Sho-saiko-to exhibited significant growth inhibition of ovarian cancer cell lines, and the mechanisms of the inhibitory effects can be attributed, in part, to apoptosis induced by Sho-saiko-to.

Abstract
Sho-saiko-to (SST) was introduced into Japan as an oriental classical medicine from China approximately 1500 years ago, and it is currently the most representative Kampo medicine (traditional Japanese medicine). SST is manufactured in Japan as an ethical drug on a modern industrial scale in which the quality of ingredients is standardized with Good Manufacturing Practices (GMP) regulation. SST is widely used for the treatment of chronic hepatitis. Experimental and clinical studies including multi-center, placebo-controlled, double-blind studies have demonstrated the various pharmacological effects of SST. SST is prepared from the hot water extraction of seven raw materials, therefore many kinds of constituents are included. Three-dimensional (3D) HPLC analysis is useful for obtaining many kinds of constituents, especially low molecular ultraviolet (UV) quenching compounds, contained in SST as well as its fractions. Fingerprint pattern provided by 3D HPLC analysis makes possible to identify the overall-viewing of SST. Databases of UV spectra of the components of medicinal herbs obtained by reversed-phase (RP) HPLC using a photodiode array (PDA) and fingerprint patterns of crude drugs made by 3D HPLC analysis facilitate the identification, analysis and quality of herbal drugs. Studies using both PDA HPLC and an amino acid analysis with a fluorometric detector have found that SST contains fifteen major low molecular compounds (i.e. baicalin, wogonin-7-O-glucuronide, liquiritin, their three aglycons, liquiritin apioside, glycyrrhizin, saikosaponin b1, saikosaponin b2, ginsenoside Rg1, ginsenoside Rb1, (6)-gingerol, (6)-shogaol and arginine). These compounds have various pharmacological actions, and are assumed to be responsible, at least partly, for the pharmacological effects of SST. Although there have only been a few investigations on high molecular compounds with pharmacological actions contained in SST, several kinds of polysaccharides have been isolated from constituent herbs of SST. This review paper summarizes analytical methods of separation, isolation and identification of compounds with biological activities from SST, which is a mixture drug of medicinal herbs. Accordingly, this paper would not focus on methods of separation, isolation and analysis of particular compounds from each constituent herb of SST.

Abstract
Sho-saiko-to (SST), a Chinese/Japanese traditional herbal medicine, has been widely used to treat chronic hepatitis in Japan, and the immunomodulatory properties of SST are likely to mediate its beneficial effect. In the present study, we examined the effects of SST and its various ingredients on the count and proliferation of T-cell subsets in cultured splenocytes and hepatic mononuclear cells. SST, wogonin-7-O-glucuronoside (a major SST ingredient), and wogonin (an intestinal metabolite of wogonin-7-O-glucuronoside) increased CD4/CD8 ratio via a decrease of CD8+ T-cell counts with no effect on CD4+ T-cell counts. Flow cytometric analyses of viability, proliferation, and cell cycle revealed that wogonin suppressed CD8+ T-cell proliferation without inducing cell death. SST and wogonin administered to mice increased the CD4/CD8 ratio in hepatic mononuclear cells but not in splenocytes. These findings suggest that SST may modulate the CD4/CD8 ratio via the selective inhibition of CD8+ T-cell proliferation by the SST ingredient wogonin-7-O-glucuronoside or its metabolite wogonin.

Abstract
Hepatitis C virus (HCV) infection is a major problem throughout the world. Combination therapy of interferon (IFN) and ribavirin is the best treatment for eradication at present, but the mechanism is not completely understood. We used the HCV replicon system to investigate this mechanism. The effects of six drugs (UDCA, glycyrrhizin, TJ-9, bezafibrate, ribavirin, and alpha-IFN 2b) on HCV subgenomic RNA (genotype 1b, NS5B 415Y) were examined by reverse transcription polymerase chain reaction, cloning and sequencing. The HCV replication was inhibited by alpha-IFN 2b (7.39-13.2% at 10 U/mL, 3.29-6.12% at 100 U/mL, 1.3-4.86% at 1000 U/mL) and by ribavirin (4.36-13.9% at 100 microg/mL), but not by the other drugs at 24-72 h after treatment. Furthermore, the combination treatment was superior to IFN monotherapy and to ribavirin monotherapy at 72 h post-treatment. Sequence analyses of the double-stranded RNA-activated protein kinase (PKR)-binding domain and flanking regions within the HCV NS5A region revealed that the total numbers of substitutions caused by ribavirin (n = 36) or combination treatment (n = 57) were more than those of IFN alone (n = 5) and controls (n = 6). The HCV replicon system is the most efficient system for HCV replication and is an excellent choice for testing anti-HCV drugs and disinfectants. Our results further suggested that the combination of alpha-IFN 2b and ribavirin might induce mutations, and inhibit HCV RNA synthesis in hepatocytes to a greater extent than ribavirin monotherapy.

Abstract
Though some herbal medicines have been shown to protect against or treat experimental liver injury in vitro, and many may possess one or a combination of antioxidant, antifibrotic, immunomodulatory, or antiviral activities, they have not been shown effective in human trials. It has been extremely difficult to construct randomized, controlled trials using complementary and alternative medicines because of an incomplete understanding of their modes of action, the lack of standardization in their manufacture, and the complexity of ingredients in any herbal extract. This may become easier once more standardized and broad-based regulatory oversight of marketing and manufacture of these products is achieved. Despite this, the use of complementary and alternative medicines is ever increasing, especially in patients having chronic liver disease. With this growing popularity, it is becoming more apparent that many of these treatments possess the potential for appreciable hepatotoxicity, in some instances resulting in significant morbidity and mortality. Until these products are more closely regulated and their advertising better scrutinized, all physicians and patients should become more familiar with the natural and alternative products that are commonly used, and recognize which can be harmful (Table 4). Better public awareness should be maintained with regard herb and prescription drug interactions.

Abstract
The use of herbal and other botanical products, including those used extensively in traditional Chinese medicine, has increased dramatically in the last decade. Yet, little scientific research exists concerning their efficacy and safety. We examined the effects of Immune+, a combination of five botanicals frequently used in traditional Chinese medicine, on the production of two cytokines. For this purpose, unstimulated or phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells from healthy volunteers were incubated with different concentrations of Immune+. The secretion of interleukin-1beta (IL-1beta) and interferon-gamma (IFN-gamma) was measured after 72 hours of incubation. At the highest concentration tested (100 micro g/ml), Immune+ significantly increased the secretion of IL-1beta. Importantly, PHA alone had no effect on IL-1beta production, and the combination of PHA with Immune+ resulted in the same increase in IL-1beta production as seen with the botanical extract alone. Immune+ did not have any detectable effect on either unstimulated or PHA-stimulated IFN-gamma synthesis. These in vitro data support the concept that Immune+ may enhance human immune responses.

Abstract
BACKGROUND In an attempt to clarify the mechanism of the effect of a herbal medicine, Saiko-keishi-to (TJ-10), which is a combination of Keishi-to (TJ-45) and Sho-saiko-to (TJ-9), we investigated the effects of these two herbal medicines and their components on pancreatic acinar cell injury models in vivo and in vitro. METHODS Four-week-old male WBN/Kob rats were fed an MB-3 pellet diet containing herbal medicine (TJ-9, TJ-10 and TJ-45). Expressions of pancreatitis-associated protein (PAP) and manganese superoxide dismutase (Mn-SOD) were analyzed with a reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. The herbal medicines and two of their components, Keihi (Cinnamomi cortex) and Shakuyaku (Paeoniae radix alba), were tested in vitro using an arginine-treated rat pancreatic acinar AR4-2J cell injury model. The inducible nitric oxide synthase (iNOS) was assayed in in vitro experiments. RESULTS TJ-45-treated WBN/Kob rats showed no evidence of pancreatitis whereas there were pathological changes of chronic pancreatitis in TJ-9-treated WBN/Kob rats. PAP was not expressed and Mn-SOD expression was increased in the TJ-10-, and TJ-45-treated rats. The herbal medicines and two components suppressed PAP mRNA expression and enhanced Mn-SOD and iNOS mRNA expression in arginine-treated AR4-2J cells. CONCLUSION These results suggest that the herbal medicine TJ-45 is effective for chronic pancreatitis caused by pancreatic ischemia.

Abstract
The RT-PCR method was employed to determine the cytokine mRNA expression of human peripheral lymphocytes induced by the Japanese herbal medicine Sho-saiko-to (TJ-9). The results showed that the mRNA expression of IL-12, IL-1beta, IL-10, TNF-alpha, G-CSF, and IFN-gamma increased after 6 hr in culture. This is the first reported finding that TJ-9 is an IFN-gamma inducer. Next, cytokine mRNA expression was semi-quantitatively measured using the Gel Doc system with a CCD camera and then statistically analyzed in order to determine which component of TJ-9 was the true cytokine inducer. The results showed that the scutellaria root is the main component inducing the cytokines, while the glycyrrhiza root is the secondary component. When the cytokine concentrations in the supernatants of cell cultures were measured by ELISA, the levels of IL-12, IL-1beta, IL-10, TNF-alpha, and G-CSF reflected mRNA expression levels in the cell fraction. However, the level of IFN-gamma was below the detectable limit. The effects of various reagents on many different kinds of cytokine mRNA expression could be analyzed objectively in a short time using the Gel Doc system. Many important findings could be demonstrated by this simple, easy, sensitive, and cheap method. After the clinical significance of cytokine analysis is confirmed, this method may become a useful clinical examination tool.

Abstract
The use of alternative medicine, including consumption of herbal products and dietary supplements, has been increasing substantially both in the United States and in Western Europe. One area that is garnering increased attention is the use of Oriental Medicine including Kampo, or Japanese herbal medicine. Herein, we review representative examples of research available on the most common use of Kampo medicinals, namely to improve the immune response. We also provide an extensive background on the history of Kampo. There are more than 210 different Kampo formulae used in Japan and most uses of Kampo are to modulate the immune response, i.e. to improve immunity. We have extracted data on seven common Kampo medicinals, and the data are reviewed with respect to in vitro and in vivo activities for both humans and experimental animals; the ingredients as well as the problems with classification of these materials are presented. Research suggests that Kampo herbals are biologically active and may have therapeutic potential. While it is believed that Kampo medicines have few side effects, there is a paucity of data on their toxicity as well as a relative lack of knowledge of the bioactive constituents and potential drug interactions of these agents.

Abstract
Sho-saiko-to (SST), a Chinese/Japanese herbal medicine (Kampo medicine) widely used to treat chronic hepatitis in Japan, is known to modulate immune responses, and thus its immunomodulating activity may be responsible for its bi-directional effects on the lungs as therapeutic efficacy in various lung diseases and involvement in development of interstitial pneumonia. We administered SST to BALB/c mice orally and examined the lung tissue levels of pro/anti-inflammatory cytokines, interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), and the effects of SST on acute lung injury induced by instillation of lipopolysaccharide (LPS) or IL-1. Although SST had no effect on lung TNF-alpha or IL-1beta level, it increased IL-6. Investigation of active fractions of SST suggested that multiple ingredients were supposed to be responsible for IL-6-inducing activity. Liquiritigenin, a metabolite of liquiritin which is one of the major ingredients in SST enhanced in vitro IL-6 production in anti-CD3 monoclonal antibody (anti-CD3 mAb)-stimulated lung mononuclear cells in a cell-type specific and dose-dependent manner. SST suppressed LPS-induced lung injury at the later phase when lung leak was evident while being ineffective on initial neutrophil sequestration to the lung in these models. These findings suggest that SST modulates lung inflammation by regulating local immune response.

Abstract
OBJECTIVE Hepatic impairment resulting from the use of conventional drugs is widely acknowledged, but there is less awareness of the potential hepatotoxicity of herbal preparations and other botanicals, many of which are believed to be harmless and are commonly used for self-medication without supervision. The aim of this paper is to examine the evidence for hepatotoxicity of botanicals and draw conclusions regarding their pathology, safety and applications. DESIGN Current literature on the hepatotoxicity of herbal drugs and other botanicals is reviewed. The aetiology, clinical picture and treatment of mushroom (Amanita) poisoning are described. RESULTS Hepatotoxic effects have been reported for some Chinese herbal medicines (such as Jin Bu Huan, Ma-Huang and Sho-saiko-to), pyrrolizidine alkaloid-containing plants, germander (Teucrium chamaedrys), chaparral (Larrea tridentata), Atractylis gummifera, Callilepsis laureola, and others. The frequency with which botanicals cause hepatic damage is unclear. There is a lack of controlled treatment trials and the few studies published to date do not clarify the incidence of adverse effects. Many plant products do not seem to lead to toxic effects in everyone taking them, and they commonly lack a strict dose-dependency. For some products, such as Sho-saiko-to, the picture is confused further by demonstrations of hepatoprotective properties for some components. Mushroom poisoning is mostly due to the accidental consumption of Amanita species. Treatment with silymarin, thioctic acid, penicillin and liver transplantation have been shown to be effective but require early diagnosis. CONCLUSIONS Severe liver injury, including acute and chronic abnormalities and even cirrhotic transformation and liver failure, has been described after the ingestion of a wide range of herbal products and other botanical ingredients, such as mushrooms. It is concluded that in certain situations herbal products may be just as harmful as conventional drugs.

Abstract
Decreased glutamine concentrations are found in patients with catabolic stress and are related to susceptibility to infections. In this study, we evaluated the role of glutamine in Th1/Th2 cytokine responses. Peripheral blood mononuclear cells were stimulated with phytohemagglutinin (PHA), live attenuated bacillus Calmette-Guérin (BCG), or measles virus in the presence of different glutamine concentrations. We found that glutamine at an optimal concentration (0.6 mM) significantly enhanced PHA-stimulated lymphocyte proliferation as well as Th1 [interferon-gamma (IFN-gamma) and interleukin-2 (IL-2)] and Th2 cytokine (IL-4 and IL-10) production. In the absence of glutamine, BCG and measles virus elicited minimal lymphocyte proliferation, whereas BCG enhanced Th1 cytokine response and measles virus promoted Th2 cytokine response. Interestingly, addition of glutamine promoted the BCG-elicited Th1 cytokine response (IFN-gamma), but suppressed the measles-induced Th2 cytokine response (IL-10). These results suggest that appropriate glutamine levels may influence host responses to different antigens and microorganisms. Furthermore, predominately Th1, but not Th2, cytokine responses required the presence of optimal concentrations of glutamine.

Abstract
BACKGROUND Traditional herbal medicine, sho-saiko-to (TJ-9), improves subjective symptoms, and a recently developed vaccine therapy reduces the viral replication in some chronic hepatitis B virus (HBV)-carriers. The study presented here considers the impact of a combination of vaccine therapy and TJ-9 and the mechanism underlying the therapeutic effect of TJ-9. MATERIALS AND METHODS HBV-transgenic mice (HBV-Tg) expressing similar levels of HBV-related antigens and HBV DNA were used as an animal model of HBV-carrier state, and were assigned to receive either a TJ-9-enriched diet or a monthly injection of vaccine containing hepatitis B surface antigen (HBsAg), or both, for 12 consecutive months. RESULTS Twelve months after starting the therapy, 9% (1 of 11), 61% (11 of 18), and 100% (10 of 10) of HBV-Tg receiving only the TJ-9-treatment, only the monthly vaccine, and both the TJ-9 and vaccine, respectively, responded to therapy and became completely negative for HBsAg. Spleen lymphocytes and antigen presenting cells (APC) from TJ-9-treated HBV-Tg produced significantly higher levels of IgM, IgG and antibodies to keyhole limpet hemocyanin (KLH) and showed significantly higher stimulatory capacity in allogenic mixed leukocyte reaction (MLR) compared with the spleen cells and APC from HBV-Tg receiving normal diet without TJ-9 (P < 0.05). CONCLUSION These data confirm the therapeutic role of TJ-9 during HBV infection and inspire optimism of a widespread use of TJ-9 during immune therapies.

Abstract
During the past 2 years, drug-induced interstitial pneumonia was reported in 66 Japanese patients, mainly among chronic hepatitis C patients, undergoing treatment with the Japanese herbal medicine "Sho-saiko-to" (TJ-9). As interstitial pneumonia is also induced by granulocyte colony-stimulating factor (G-CSF), we examined the effects of TJ-9 on G-CSF production in peripheral blood mononuclear cells. In patients with hepatitis B or C, G-CSF production in the absence of any stimulation was significantly lower than healthy controls (p < 0.01). G-CSF production increased along with the increase of TJ-9 levels, and this could induce excessive production of G-CSF in hepatitis C patients, and this may be a cause of interstitial pneumonia.
