School of Bio-engineering and Biosciences, VIT University, Vellore-632 014, Tamil Nadu, India.
In the present study, we have investigated the efficacy of Indian ayurvedic herbal formulation Triphala on monosodium urate crystal-induced inflammation in mice; an experimental model for gouty arthritis and compared it with that of the non-steroidal anti-inflammatory drug, Indomethacin. The anti-arthritic effect of Triphala was evaluated by measuring changes in the paw volume, lysosomal enzyme activities, lipid peroxidation, anti-oxidant status and inflammatory mediator TNF-alpha in control and monosodium urate crystal-induced mice. The levels of beta-glucuronidase and lactate dehydrogenase were also measured in monosodium urate crystal-incubated polymorphonuclear leucocytes (PMNL). Triphala treatment (1 gm/kg/b.w. orally) significantly inhibited the paw volume and the levels of lysosomal enzymes, lipid peroxidation and inflammatory mediator tumour necrosis factor-alpha; however the anti-oxidant status was found to be increased in plasma, liver and spleen of monosodium urate crystal-induced mice when compared to control mice. In addition, beta-glucuronidase and lactate dehydrogenase level were reduced in Triphala (100 microg/ml) treated monosodium urate crystal-incubated polymorphonuclear leucocytes. In conclusion, the results obtained clearly indicated that Triphala exerted a strong anti-inflammatory effect against gouty arthritis

In the present study, attempts have been made to evaluate the antiarthritic effect of the Indian Ayurvedic herbal formulation Triphala on adjuvant-induced arthritis in mice and to compare it with that of the non-steroidal antiinflammatory drug indomethacin. Arthritis was induced by intradermal injection of complete Freund's adjuvant (0.1 mL) into the right hind paw of Swiss albino mice. Triphala (1 g/kg/bxwt) and indomethacin (3 mg/kg/bxwt) were administered orally for 8 days (from day 11 to 18) after adjuvant injection. The levels of lysosomal enzymes, tissue marker enzymes, glycoproteins and paw thickness were increased in adjuvant-induced arthritic animals. The body weight was found to be reduced when compared with the control animals. These physical and biochemical changes observed in arthritic animals were altered significantly to near normal conditions after oral administration of Triphala (1 g/kg/bxwt). The results obtained clearly indicate the fact that the Indian Ayurvedic herbal formulation Triphala has promising antiinflammatory activity.

Myrrh (guggulu) oleoresin from the Commiphora mukul tree is an important component of antiarthritic drugs in Ayurvedic medicine. Clinical data suggest that elevated levels of hyaluronidase and collagenase type 2 enzymes contribute significantly to cartilage degradation. Triphala guggulu (TG) is a guggulu-based formulation used for the treatment of arthritis. We assessed the chondroprotective potential of TG by examining its effects on the activities of pure hyaluronidase and collagenase type 2 enzymes. Triphala shodith guggulu (TSG), an intermediate in the production of TG, was also examined. A spectrophotometric method was used to assay Hyaluronidase activity, and to detect potential Hyaluronidase inhibitors. Aqueous and hydro-alcoholic extracts of TSG showed weak but dose-dependent inhibition of hyaluronidase activity. In contrast, the TG formulation was 50 times more potent than the TSG extract with respect to hyaluronidase inhibitory activity. A validated X-ray film-based assay was used to measure the gelatinase activity of pure collagenase type 2. Hydro-alcoholic extracts of the TG formulation were 4 times more potent than TSG with respect to collagenase inhibitory activity. Components of Triphala were also evaluated for their inhibitory activities on hyaluronidase and collagenase. This is the first report to show that the T2 component of Triphala (T.chebula) is a highly potent hyaluronidase and collagenase inhibitor. Thus, the TG formulation inhibits two major enzymes that can degrade cartilage matrix. Our study provides the first in vitro preclinical evidence of the chondroprotective properties of TG.

Natural products as a gold mine for arthritis treatment.Khanna D, Sethi G, Ahn KS, Pandey MK, Kunnumakkara AB, Sung B, Aggarwal A, Aggarwal BB.
Division of Immunology, Department of Medicine, University of Cincinnati, Cincinnati, OH, USA.
Arthritis, an inflammation of the joints, is usually a chronic disease that results from dysregulation of pro-inflammatory cytokines (e.g. tumour necrosis factor and interleukin-1beta) and pro-inflammatory enzymes that mediate the production of prostaglandins (e.g. cyclooxygenase-2) and leukotrienes (e.g. lipooxygenase), together with the expression of adhesion molecules and matrix metalloproteinases, and hyperproliferation of synovial fibroblasts. All of these factors are regulated by the activation of the transcription factor nuclear factor-kappaB. Thus, agents that suppress the expression of tumour necrosis factor-alpha, interleukin-1beta, cyclooxygenase-2, lipooxygenase, matrix metalloproteinases or adhesion molecules, or suppress the activation of NF-kappaB, all have potential for the treatment of arthritis. Numerous agents derived from plants can suppress these cell signaling intermediates, including curcumin (from turmeric), resveratrol (red grapes, cranberries and peanuts), tea polyphenols, genistein (soy), quercetin (onions), silymarin (artichoke), guggulsterone (guggul), boswellic acid (salai guggul) and withanolides (ashwagandha). Indeed, several preclinical and clinical studies suggest that these agents have potential for arthritis treatment. Although gold compounds are no longer employed for the treatment of arthritis, the large number of inexpensive natural products that can modulate inflammatory responses, but lack side effects, constitute 'goldmines' for the treatment of arthritis.

Effect of food intake on the bioavailability of boswellic acids from a herbal preparation in healthy volunteers.Sterk V, Büchele B, Simmet T.
Department of Pharmacology of Natural Products & Clinical Pharmacology, University of Ulm, Ulm, Germany.
In this study we investigated the effects of concomitant food intake on the bioavailability of distinct boswellic acids (BAs) from the test preparation BSE-018, a dry extract from Boswellia serrata gum resin. In a randomised, open, single-dose, two-way crossover study, healthy male subjects received three capsules of BSE-018 equivalent to 786 mg dry extract of Boswellia serrata gum resin either in the fasted state or together with a standardised high-fat meal. BA plasma concentrations were analysed for up to 60 h after oral dosing by reversed phase HPLC. As compared to the fasted state (treatment A), the administration of BSE-018 concomitantly with a high-fat meal (treatment B) led to several-fold increased areas under the plasma concentration-time curves as well as peak concentrations of beta-boswellic acid (betaBA), 11-keto-beta-boswellic acid (KbetaBA) and acetyl-11-keto-beta-boswellic acid (AKbetaBA). Plasma levels of both acetyl-alpha-boswellic acid (AalphaBA) and alphaBA became only detectable when administered with treatment B, i.e., the high-fat meal. Accordingly, pharmacokinetic data could be calculated for betaBA, KbetaBA and AKbetaBA (treatment A) and for betaBA, KbetaBA, AKbetaBA, alphaBA, and AalphaBA (treatment B). For the first time these data reveal detailed kinetics of BAs after oral dosing of an extract and demonstrate a profound effect of food intake on the pharmacokinetic profile of the BAs. This finding should be very important whenever BAs would be considered for therapeutic use

Acute treatment of rheumatoid rats with an extract from the roots of Gentiana macrophylla (Gentianaceae) produced a significant inhibitory effect on rheumatoid arthritis (RA). When rats were administered the Gentiana macrophylla extract orally at a daily dose of 100 mg/kg body weight, the prostaglandin E2 (PGE2) levels in the inflammatory tissues, sole thickness, and ankle circumferences of feet were significantly decreased. The anti-inflammatory activity observed in Gentiana macrophylla is comparable to that observed in prednisone. These observations suggest that Gentiana macrophylla displays considerable potency in anti-inflammatory action and could be used as an anti-inflammatory agent in the control of inflammation of rheumatoid arthritis

[Observation on the treatment of systemic lupus erythematous with a Gentiana macrophylla complex tablet and a minimal dose of prednisone][Article in Chinese]
Yuan ZZ, Feng JC.
Sixty-two cases of systemic lupus erythematous (SLE) treated with Tab. Gentiana macrophylla complex 5 tablets three times per day or 10 tablets twice per day and prednisone 10-30 mg per day were reported. As controls, 19 cases of SLE were treated with prednisone alone at the same time. The results showed complete remission in 86.46% (50/62) cases in the observation group and 31.57% (6/19) cases in the control group. Eight cases of SLE treated with Tab. Gentiana m. complex alone also achieved complete remission in 6 cases and improvement in 2. There was very significant statistical difference between the two groups (P less than 0.001). The Tab. Gentiana m. complex was more effective on the improvement of nephropathy, arthralgia, erythema and restoration of ESR, LE cells and CH50, C3 than prednisone alone. No apparent side effects of Tab. Gentiana m. complex were found in this observation.

Rehmannia, a traditional Chinese medical herb, has a long history in age-related disease therapy. Previous work has indicated that catalpol is a main active ingredient performing neuroprotective effect in rehmannia, while the mechanism underlying the effect remains poorly understood. In this study, we attempt to investigate the effect of catalpol on presynaptic proteins and explore a potential mechanism. The hippocampal levels of GAP-43 and synaptophysin in 3 groups of 4 months (young group), 22-24 months (aged group) and catalpol-treated 22-24 months (catalpol-treated group) rats were evaluated by western blotting. Results clearly showed a significant decrease in synaptophysin (46.6%) and GAP-43 (61.4%) levels in the aged group against the young animals and an increase (45.0% and 31.8% respectively) in the catalpol-treated aged rats in comparison with the untreated aged group. In particular, synaptophysin immunoreactivity (OD) in the dentate granule layer of the hippocampus was increased 0.0251 in the catalpol-treated group as compared with the aged group. The study also revealed a catalpol-associated increase of PKC and BDNF in the hippocampus of the catalpol-treated group in comparison with the aged rats and highly correlated with synaptophysin and GAP-43. Such positive correlations between presynaptic proteins and signaling molecules also existed in the young group. These results suggested that catalpol could increase presynaptic proteins and up-regulate relative signaling molecules in the hippocampus of the aged rats. Consequently, it seemed to indicate that catalpol might ameliorate age-related neuroplasticity loss by "normalizing" presynaptic proteins and their relative signaling pathways in the aged rats.

[Boswellic acids (components of frankincense) as the active principle in treatment of chronic inflammatory diseases][Article in German]
Lehrstuhl Pharmakologie für Naturwissenschaftler, Pharmazeutisches Institut der Universität Tübingen, Deutschland. email@example.com
Preparations from the gum resin of Boswellia serrata have been used as a traditional remedy in Ayurvedic medicine in India for the treatment of inflammatory diseases. Compounds from the gum with genuine antiinflammatory effects are pentacyclic triterpenes of the boswellic acid type. Boswellic acids inhibit the leukotriene biosynthesis in neutrophilic granulocytes by a non-redox, noncompetitive inhibition of 5-lipoxygenase. The effect is triggered by boswellic acids binding to the enzyme. Moreover certain boswellic acids have been described to inhibit elastase in leukocytes, to inhibit proliferation, induce apoptosis and to inhibit topoisomerases of leukoma- and glioma cell lines. A series of chronic inflammatory diseases are thought to be perpetuated by leukotrienes. In clinical trials promising results were observed in patients with rheumatoid arthritis, chronic colitis, ulcerative colitis, Crohn's disease, bronchial asthma und peritumoral brains edemas.

A review of complementary and alternative approaches to immunomodulation.Clarke JO, Mullin GE.
Division of Gastroenterology, The Johns Hopkins University School of Medicine, Baltimore, MD 21287, USA. firstname.lastname@example.org
Current Western therapies for inflammatory diseases are suboptimal; increasingly, patients are turning to complementary and alternative medicine for symptom relief and improved quality of life. There is emerging evidence that many of these therapies have the ability to modulate the immune system and disrupt the proinflammatory cascade through a variety of mechanisms, including antioxidant effects, alterations in cell signaling (in particular the nuclear factor (NF)-kappaB pathway), cytokines, proinflammatory mediators, and disruption of bacterial flora. Using inflammatory bowel disease (IBD) as a model of inflammation, we explore the principal complementary and alternative medicine treatments that show promise in this regard, namely, resveratrol, green tea, curcumin, boswellia, fish oil, vitamin D, and probiotics. With each agent, we detail the mechanisms that have been described with regard to immune modulation, discuss the medical conditions for which it has been evaluated, and explore the data to date for the prevention or treatment of IBD.

Incensole acetate, a novel anti-inflammatory compound isolated from Boswellia resin, inhibits nuclear factor-kappa B activation.Moussaieff A, Shohami E, Kashman Y, Fride E, Schmitz ML, Renner F, Fiebich BL, Munoz E, Ben-Neriah Y, Mechoulam R.

Boswellia resin is a major anti-inflammatory agent in herbal medical tradition, as well as a common food supplement. Its anti-inflammatory activity has been attributed to boswellic acid and its derivatives. Here, we re-examined the anti-inflammatory effect of the resin, using inhibitor of nuclear factor-kappaB alpha (IkappaB alpha) degradation in tumor necrosis factor (TNF) alpha-stimulated HeLa cells for a bioassay-guided fractionation. We thus isolated two novel nuclear factor-kappaB (NF-kappaB) inhibitors from the resin, their structures elucidated as incensole acetate (IA) and its nonacetylated form, incensole (IN). IA inhibited TAK/TAB-mediated IkappaB kinase (IKK) activation loop phosphorylation, resulting in the inhibition of cytokine and lipopolysaccharide-mediated NF-kappaB activation. It had no effect on IKK activity in vitro, and it did not suppress IkappaB alpha phosphorylation in costimulated T-cells, indicating that the kinase inhibition is neither direct nor does it affect all NF-kappaB activation pathways. The inhibitory effect seems specific; IA did not interfere with TNFalpha-induced activation of c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase. IA treatment had a robust anti-inflammatory effect in a mouse inflamed paw model. Cembrenoid diterpenoids, specifically IA and its derivatives, may thus constitute a potential novel group of NF-kappaB inhibitors, originating from an ancient anti-inflammatory herbal remedy.

BACKGROUND AND AIMS: The objective of this study was to investigate the effect of Boswellia serrata extract (BSE) on symptoms, quality of life, and histology in patients with collagenous colitis. MATERIALS AND METHODS: Patients with chronic diarrhea and histologically proven collagenous colitis were randomized to receive either oral BSE 400 mg three times daily for 6 weeks or placebo. Complete colonoscopy and histology were performed before and after treatment. Clinical symptoms and quality of life were assessed by standardized questionnaires and SF-36. The primary endpoint was the percentage of patients with clinical remission after 6 weeks (stool frequency<or=3 soft /solid stools per day on average during the last week). Patients of the placebo group with persistent diarrhea received open-label BSE therapy for a further 6 weeks. RESULTS: Thirty-one patients were randomized; 26 patients were available for per-protocol-analysis. After 6 weeks, the proportion of patients in clinical remission was higher in the BSE group than in the placebo group (per protocol 63.6%; 95%CI, 30.8-89.1 vs 26.7%, 95%CI, 7.7-55.1; p=0.04; intention-to-treat 43.8% vs 26.7%, p=0.25). Compared to placebo, BSE treatment had no effect on histology and quality of life. Five patients discontinued BSE treatment prematurely. Discontinuation was due to adverse events (n=1), unwillingness to continue (n=3), or loss to follow-up for unknown reasons (n=1). Seven patients received open-label BSE therapy, five of whom achieved complete remission. CONCLUSIONS: Our study suggests that BSE might be clinically effective in patients with collagenous

Pure compound from Boswellia serrata extract exhibits anti-inflammatory property in human PBMCs and mouse macrophages through inhibition of TNFalpha, IL-1beta, NO and MAP kinases.Gayathri B, Manjula N, Vinaykumar KS, Lakshmi BS, Balakrishnan A.
Centre for Biotechnology, Anna University, Chennai, India.
The aim of the present study is to probe the anti-inflammatory potential of the plant Boswellia serrata by studying the effect of the crude extract and the pure compound isolated from it on key inflammatory mediators like TNFalpha, IL-1beta, and NO thus enabling the understanding of the key signaling events involved. The crude methanolic extract and the pure compound were analysed for their inhibitory effect on TNFalpha, IL-1beta and IL-6. The results demonstrated that all three cytokines are down regulated when PBMCs are cultured in the presence of crude extract or the pure compound at various time points. Observations on Th1/Th2 cytokines revealed marked down regulation of Th1 cytokines IFNgamma and IL-12 while the Th2 cytokines IL-4 and IL-10 were up regulated upon treatment with crude extract and pure compound. The extract and the pure compound isolated also showed considerable inhibition of NO production in activated RAW 264.7 cells, possibly via suppression of inducible NO synthase mRNA expression. Further to elucidate the underlying mechanism of action the effect of 12-ursene 2-diketone on LPS-induced activation of MAPK has also been examined. Our results demonstrated that 12-ursene 2-diketone inhibits the expression of pro-inflammatory cytokines and mediators via inhibition of phosphorylation of the MAP kinases JNK and p38 while no inhibition was seen in ERK phosphorylation in LPS-stimulated PBMCs. The above study therefore indicates that the crude methanolic extract and the isolated pure compound are capable of carrying out a natural anti-inflammatory activity at sites where chronic inflammation is present by switching off the pro-inflammatory cytokines and mediators, which initiate the process.

A 32-Week Randomized, Placebo-Controlled Clinical Evaluation of RA-11, an Ayurvedic Drug, on Osteoarthritis of the Knees.Chopra A, Lavin P, Patwardhan B, Chitre D.
From the *Center for Rheumatic Diseases, Inlaks and Budhrani Hospital, Bharati Hospital Medical College (Deemed University), Pune, India; †Averion, Inc., Framingham, Massachusetts; the ‡School of Health Sciences, University of Pune, India; and §BIO-VED Pharmaceuticals, Inc., San Jose, California.
BACKGROUND:: The ancient Indian (Asian) Ayurvedic medicinal system uses herbomineral drugs to treat arthritis. Despite centuries of use, very few have been tested by drug trials. RA-11 (ARTREX, MENDAR), a standardized multiplant Ayurvedic drug (Withania somnifera, Boswellia serrata, Zingiber officinale, and Curcuma longa) is currently used to treat arthritis. OBJECTIVE:: The objective of this study was to evaluate the efficacy and safety of RA-11 in patients with symptomatic osteoarthritis (OA) of the knees. METHODS:: A total of 358 patients with chronic knee pain were screened free-of-cost in "arthritis camps" in an Indian metropolis. Ninety patients with primary OA of the knees (ACR classification; Arthritis Rheum 1986;29:1039-1049) were found eligible (postanalgesic washout pain visual analog score [VAS] >/=40 mm in either or both knees on body weight-bearing activities) to enroll into a randomized, double-blind, placebo-controlled, parallel efficacy, single-center, 32-week drug trial (80% power to detect 25% difference, P = 0.05, 2-sided). Concurrent analgesics/nonsteroidal antiinflammatory drugs and steroids in any form were not allowed. Lifestyle and/or dietary restrictions, as per routine Ayurveda practices, were not imposed. Pain VAS (maximum pain in each knee recorded by the patient during the preceding 48 hours) and modified WOMAC (Western Ontario McMaster University OA Index, Likert scale, version 3.0) were the primary efficacy variables. The WOMAC section on "physical function difficulty" was modified for Indian use and validated before the trial. Routine laboratory testing was primarily done to monitor drug safety. At baseline, the groups (active = 45, placebo = 45) were well matched for several measures (mean pain VAS: active = 6.17; placebo = 6.5). RESULTS:: 1) Efficacy: Compared with placebo, the mean reduction in pain VAS at week 16 (active = 2.7, placebo = 1.3) and week 32 (active = 2.8, placebo = 1. in the active group was significantly (P <0.05, analysis of variance [ANOVA]) better. Similarly, the improvement in the WOMAC scores at week 16 and week 32 were also significantly superior (P <0.01, ANOVA) in the active group. 2) Safety: Both the groups reported mild adverse events (AE) without any significant difference. 3) Withdrawals: Twenty-eight patients were discontinued. None reported drug-related toxicity. The majority failed follow up/compliance. No differences were observed between the groups. CONCLUSION:: This controlled drug trial demonstrates the potential efficacy and safety of RA- 11 in the symptomatic treatment of OA knees over 32 weeks of therapy.

An open multi-centre veterinary clinical trial, comparing conditions before and after treatment with a herbal dietary supplement consisting of a natural resin extract of Boswellia serrata, was conducted by 10 practicing veterinarians in Switzerland. This traditional plant-based supplement is known for its anti-rheumatic and anti-inflammatory properties. 29 dogs with manifestations of chronic joint and spinal disease were enrolled. Osteoarthritis and degenerative conditions were confirmed radiologically in 25 of 29 cases. The resin extract (BSB108, product of Bogar AG) was administered with the regular food at a dose of 400 mg/10 kg body weight once daily for 6 weeks. Already after two weeks of treatment, an overall efficacy of the dietary supplement was evident in 71% of 24 eligible dogs. A statistically significant reduction of severity and resolution of typical clinical signs in individual animals, such as intermittent lameness, local pain and stiff gait, were reported after 6 weeks. Effects of external factors that aggravate lameness, such as "lameness when moving" and "lameness after a long rest" diminished gradually. In 5 dogs, reversible brief episodes of diarrhea and flatulence occurred, but only once was a relationship to the study preparation suspected. Because quality and stability of the resin extract were ensured, these data suggest that a standardized preparation can be recommended as a herbal dietary supplement providing symptomatic support in canine osteoarthritic disease.

Institute of Virology, Chinese Academy of Preventive Medicine, Beijing.
Ether extracts of 1693 Chinese medicinal herbs and plants from 268 families were studied for the induction of Epstein-Barr viral (EBV) early antigen (EA) expression in the Raji cell line. Fifty-two from 18 families were found to have inducing activity. Twenty-five and seven of them were from Euphorbiaceae and Thymelaeaeeae, respectively. Some of them, such as Croton tiglium, Euphorbia kansui, Daphne genkwa, Wikstroemia chamaedaphne, Wikstroemia indica, Prunus mandshurica Koehne and Achyranthes bidentata are commonly used drugs. The significance of these herbs in the activation of EBV in vivo and their relation to the development of nasopharyngeal carcinoma were discussed.

At the present, medication of dementia is limited to symptomatic treatments such as the use of cholinesterase inhibitors. To cure dementia completely, that is regaining neuronal function, reconstruction of neuronal networks is necessary. Therefore, we have been exploring antidementia drugs based on reconstructing neuronal networks in the damaged brain and found that withanoside IV (a constituent of Ashwagandha; the root of Withania somnifera) induced neurite outgrowth in cultured rat cortical neurons. Oral administration of withanoside IV (10 micromol/kg/day) significantly improved memory deficits in Abeta(25-35)-injected (25 nmol, i.c.v.) mice and prevented loss of axons, dendrites, and synapses. Sominone, an aglycone of withanoside IV, was identified as the main metabolite after oral administration of withanoside IV. Sominone (1 microM) induced axonal and dendritic regeneration and synaptic reconstruction significantly in cultured rat cortical neurons damaged by 10 microM Abeta(25-35). These data suggest that orally administrated withanoside IV may ameliorate neuronal dysfunction in Alzheimer's disease and that the active principle after metabolism is sominone.

Withanolides potentiate apoptosis, inhibit invasion, and abolish osteoclastogenesis through suppression of nuclear factor-kappaB (NF-kappaB) activation and NF-kappaB-regulated gene expression.Ichikawa H, Takada Y, Shishodia S, Jayaprakasam B, Nair MG, Aggarwal BB.

The plant Withania somnifera Dunal (Ashwagandha), also known as Indian ginseng, is widely used in the Ayurvedic system of medicine to treat tumors, inflammation, arthritis, asthma, and hypertension. Chemical investigation of the roots and leaves of this plant has yielded bioactive withanolides. Earlier studies showed that withanolides inhibit cyclooxygenase enzymes, lipid peroxidation, and proliferation of tumor cells. Because several genes that regulate cellular proliferation, carcinogenesis, metastasis, and inflammation are regulated by activation of nuclear factor-kappaB (NF-kappaB), we hypothesized that the activity of withanolides is mediated through modulation of NF-kappaB activation. For this report, we investigated the effect of the withanolide on NF-kappaB and NF-kappaB-regulated gene expression activated by various carcinogens. We found that withanolides suppressed NF-kappaB activation induced by a variety of inflammatory and carcinogenic agents, including tumor necrosis factor (TNF), interleukin-1beta, doxorubicin, and cigarette smoke condensate. Suppression was not cell type specific, as both inducible and constitutive NF-kappaB activation was blocked by withanolides. The suppression occurred through the inhibition of inhibitory subunit of IkappaB alpha kinase activation, IkappaB alpha phosphorylation, IkappaB alpha degradation, p65 phosphorylation, and subsequent p65 nuclear translocation. NF-kappaB-dependent reporter gene expression activated by TNF, TNF receptor (TNFR) 1, TNFR-associated death domain, TNFR-associated factor 2, and IkappaB alpha kinase was also suppressed. Consequently, withanolide suppressed the expression of TNF-induced NF-kappaB-regulated antiapoptotic (inhibitor of apoptosis protein 1, Bfl-1/A1, and FADD-like interleukin-1beta-converting enzyme-inhibitory protein) and metastatic (cyclooxygenase-2 and intercellular adhesion molecule-1) gene products, enhanced the apoptosis induced by TNF and chemotherapeutic agents, and suppressed cellular TNF-induced invasion and receptor activator of NF-kappaB ligand-induced osteoclastogenesis. Overall, our results indicate that withanolides inhibit activation of NF-kappaB and NF-kappaB-regulated gene expression, which may explain the ability of withanolides to enhance apoptosis and inhibit invasion and osteoclastogenesis.

Immunomodulatory role of Withania somnifera root powder on experimental induced inflammation: An in vivo and in vitro study.Rasool M, Varalakshmi P.
Department of Biosciences, Vellore Institute of Technology, Deemed University, Vellore-632 014, India. email@example.com
The aqueous suspension of Withania somnifera root powder was investigated for their in vivo and in vitro immunomodulatory properties. W. somnifera showed potent inhibitory activity towards the complement system, mitogen induced lymphocyte proliferation and delayed-type hypersensitivity reaction. Administration of W. somnifera root powder did not have a significant effect on humoral immune response in rats.

The reconstruction of neuronal networks in the damaged brain is necessary for the therapeutic treatment of neurodegenerative diseases. We have screened the neurite outgrowth activity of herbal drugs, and identified several active constituents. In each compound, neurite outgrowth activity was investigated under amyloid-beta-induced neuritic atrophy. Most of the compounds with neurite regenerative activity also demonstrated memory improvement activity in Alzheimer's disease-model mice. Protopanaxadiol-type saponins in Ginseng drugs and their metabolite, M1 (20-O-beta-D-glucopyranosyl-(20S)-protopanaxadiol), showed potent regeneration activity for axons and synapses, and amelioration of memory impairment. Withanolide derivatives (withanolide A, withanoside IV, and withanoside VI) isolated from the Indian herbal drug Ashwagandha, also showed neurite extension in normal and damaged cortical neurons. Trigonelline, a constituent of coffee beans, demonstrated the regeneration of dendrites and axons, in addition to memory improvement. 2005 S. Karger AG, Basel

Celastrus aculeatus Merr. suppresses the induction and progression of autoimmune arthritis by modulating immune response to heat-shock protein 65.Tong L, Moudgil KD.
Department of Microbiology and Immunology, University of Maryland School of Medicine, Baltimore, MD 21201, USA.
Complementary and alternative medicine products are increasingly being used for the treatment of autoimmune diseases. However, the mechanisms of action of these agents are not fully defined. Using the rat adjuvant arthritis (AA) model of human rheumatoid arthritis, we determined whether the ethanol extract of Celastrus aculeatus Merr. (Celastrus), a Chinese herb, can down-modulate the severity of AA, and also examined the Celastrus-induced changes in immune responses to the disease-related antigen mycobacterial heat-shock protein 65 (Bhsp65). AA was induced in the Lewis (LEW; RT.1l) rat by immunization subcutaneously with heat-killed M. tuberculosis H37Ra (Mtb). Celastrus was fed to LEW rats by gavage daily, beginning either before Mtb challenge (preventive regimen) or after the onset of AA (therapeutic regimen). An additional group of rats was given methotrexate for comparison. All rats were graded regularly for the signs of arthritis. In parallel, the draining lymph node cells of Celastrus-treated rats were tested for proliferative and cytokine responses, whereas their sera were tested for the inflammatory mediator nitric oxide. Celastrus feeding suppressed both the induction as well as the progression of AA, and the latter effect was comparable to that of methotrexate. Celastrus treatment induced relative deviation of the cytokine response to anti-inflammatory type and enhanced the production of anti-Bhsp65 antibodies, which are known to be protective against AA. Celastrus feeding also reduced the levels of nitric oxide. On the basis of our results, we suggest further systematic exploration of Celastrus as an adjunct therapeutic modality for rheumatoid arthritis.

Anti-arthritic effects of Ephedra sinica STAPF herb-acupuncture: inhibition of lipopolysaccharide-induced inflammation and adjuvant-induced polyarthritis.Yeom MJ, Lee HC, Kim GH, Lee HJ, Shim I, Oh SK, Kang SK, Hahm DH.
Laboratory of Acupuncture & Meridian, Department of Oriental Medical Science, Graduate School of East-West Medical Science, Kyung-Hee University, Kyungki-do, Korea.
Anti-inflammatory and anti-arthritic effects of water distillates of Ephedra sinica STAPF (ES), in herb-acupuncture, on the inflammatory responses of arthritis was investigated using phorbol 12-myristate 13-acetate (PMA)/lipopolysaccharide (LPS)-induced human macrophage and adjuvant-induced arthritic rat. The luciferase reporter vectors driven by the tumor necrosis factor (TNF)-alpha and cyclooxygenase-2 promoters were transiently transfected into U937 cells, which were then differentiated and stimulated by PMA and LPS, respectively, to develop an in vitro anti-inflammation assay system. The luciferase activities, observed in the activated U937 cells, were significantly inhibited by ES herb-acupuncture, compared to those of PD98509 and berberine. To evaluate ES herb-acupuncture as a novel anti-arthritic therapy, a polyarthritic rat model was developed using heat-killed Mycobacterium tuberculosis, and 50 mul of ES distillate was subcutaneously injected into the ST36 acupoint on each knee joint. While the articular indexes of arthritic rats were evidently decreased by ES herb-acupuncture, their body weights did not regain their initial levels. This may be due to the accelerating effects of ES on weight-loss and fat consumption. The mRNA expressions of TNF-alpha and interleukin (IL)-6 genes, which were closely stimulated in the arthritic rat joints, were found to be restored to the normal levels through the ES treatment. In the case of IL-1beta, the recovery was not significant but substantial. The anti-arthritic effect of ES herb-acupuncture was not found in the ES-treated/non-acupoint group. In conclusion, the ES herb-acupuncture into the ST36 acupoint was found to be effective in alleviating the inflammatory response and thus arthritic symptoms in adjuvant-induced arthritic rats.

OBJECTIVE: To find out the specialities of the effect of crude and processed Herba Siegesbeckiae on anti-inflammation and anti-rheumatism. METHOD: Experiments were made on rats with swelling foot induced by carrageenin; experiments were made on mice with swelling ear induced by xylol; experiments were made on rats with chronic granuloma; experiments were made on rats with adjuvant arthritis. RESULT: Foot swelling induced by carrageenin could be diminished with crude and processed Herba Siegesbeckiae at 6.0, 2.0 g x kg(-1). The rate of inhibition of foot swelling was more than 40%, effect of the crude drug was better than that of the processed one; both of them at 6.0, 2.0 g x kg(-1) could protect rats from primary and continuous lesion of adjuvant arthritis. The effect of the processed herb was obviously better than that of the crude one in its starting minute, strength and sustaining time. CONCLUSION: The processed Herba Siegesbeckiae has obvious inhibition effect on immune inflammation. It is better than the crude Herb. Both of them have obvious inhibition effect on inflammation caused by carrageenin, with no distinct difference.

Plant alkaloid tetrandrine downregulates IkappaBalpha kinases-IkappaBalpha-NF-kappaB signaling pathway in human peripheral blood T cell.Ho LJ, Juan TY, Chao P, Wu WL, Chang DM, Chang SY, Lai JH.
Division of Gerontology Research, National Health Research Institute, Taipei, Taiwan, ROC.
Plant alkaloid tetrandrine (Tet), purified from Chinese herb Han-Fang Chi, is a potent immunomodulator used to treat rheumatic disorders, silicosis and hypertension in mainland China. We previously demonstrated that Tet effectively suppresses cytokine production and proliferation of CD28-costimulated T cells. In the present study, we investigated the possible involvement of nuclear factor kappa B (NF-kappaB) transcription factors, critical in CD28 costimulation, in Tet-mediated immunosuppression in human peripheral blood T cells. We showed that Tet inhibited NF-kappaB DNA-binding activities induced by various stimuli, including CD28 costimulation. At equal molar concentrations, Tet was as strong as methotrexate in suppressing CD28-costimulated NF-kappaB activities. Since Tet itself did not affect NF-kappaB binding to its corresponding DNA sequence, the results suggested that Tet might regulate NF-kappaB upstream signaling molecules. Further studies demonstrated that Tet could prevent the degradation of IkappaBalpha and inhibit nuclear translocation of p65 by blocking IkappaBalpha kinases alpha and beta activities. In addition, the activation of mitogen-activated protein kinases such as c-jun N-terminal kinase, p38 and extracellular signal-regulated kinase and activator protein-1 DNA-binding activity were all downregulated by Tet. Transfection assays performed in purified human peripheral blood T cells also confirmed the inhibition of NF-kappaB transcriptional activity by Tet. When four Tet analogues were readily compared, dauricine appeared to preserve the most potent inhibition on CD28-costimulated but not on H(2)O(2)-induced NF-kappaB DNA-binding activities. Our results provide the molecular basis of immunomodulation of Tet for being a potential disease-modifying antirheumatic drug in the therapy of autoimmune disorders like rheumatoid arthritis.

Chinese herbs as immunomodulators and potential disease-modifying antirheumatic drugs in autoimmune disorders.Ho LJ, Lai JH.
Division of Gerontology Research, National Health Research Institute,Taipei, Taiwan, ROC. email@example.com
Autoimmune diseases are a group of illnesses with multiple organ involvement. The prototype of this group of disorders is rheumatoid arthritis (RA) that aside from systemic organ involvement mainly presents with progressive destruction of many joints. Both activation and defective apoptosis of immune effector cells like T and B lymphocytes and macrophages play critical roles in the pathogenesis of autoimmune disorders. Current therapy for autoimmune diseases recommends a combination of several disease-modifying antirheumatic drugs (DMARDs) that preserve different immunomodulatory mechanisms. Because of limited success in prevention of RA joint destruction for currently available DMARDs, the development of more effective and less toxic DMARDs has been one of the major goals for pharmaceutical companies. The introduction of leflunomide and anti-tumor necrosis factor alpha therapies to the market recently serves as examples. In this context, the experience from ancient Chinese medicine gives an alternative consideration looking for potential DMARDs. Two commonly prescribed Chinese antirheumatic herbs are Tripterygium wilfordii hook f (TWHf) and tetrandrine (Tet) that preserve both anti-inflammatory and immunosuppressive effects. Importantly, the TWHf- or Tet-mediated immunomodulatory mechanisms are evidently different from the known DMARDs. The synergistic effects have also been demonstrated between these two Chinese antirheumatic herbs and DMARDs like FK506, cyclosporin and possibly chloroquine. Another potential Chinese herb for this consideration is Ginkgo biloba. This review summarizes evidence-based in vivo and in vitro studies on Chinese herbs as immunomodulators and potential DMARDs.

Immunosuppressive and anti-inflammatory mechanisms of triptolide, the principal active diterpenoid from the Chinese medicinal herb Tripterygium wilfordii Hook. f.Qiu D, Kao PN.
Division of Pulmonary and Critical Care Medicine, Stanford University Medical Center, Stanford, California 94305, USA. firstname.lastname@example.org
Extracts of Tripterygium wilfordii hook. f. (leigong teng, Thundergod vine) are effective in traditional Chinese medicine for treatment of immune inflammatory diseases including rheumatoid arthritis, systemic lupus erythematosus, nephritis and asthma. Characterisation of the terpenoids present in extracts of Tripterygium identified triptolide, a diterpenoid triepoxide, as responsible for most of the immunosuppressive, anti-inflammatory and antiproliferative effects observed in vitro. Triptolide inhibits lymphocyte activation and T-cell expression of interleukin-2 at the level of transcription. In all cell types examined, triptolide inhibits nuclear factor-kappaB transcriptional activation at a unique step in the nucleus after binding to DNA. Further characterisation of the molecular mechanisms of triptolide action will serve to elucidate pathways of immune system regulation.

Immunomodulatory effects and mechanisms of plant alkaloid tetrandrine in autoimmune diseases.Lai JH.
Rheumatology/Immunology and Allergy, Department of Medicine, Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan, China. email@example.com
Autoimmune diseases characterized by activation of immune effector cells and damage of target organs are currently treated with a combination of several disease-modifying antirheumatic drugs (DMARDs) that preserve different immunomodulatory mechanisms. Such a combination treatment strategy not only provides synergistic effects but also reduces side effects from individual drug. Tetrandrine (Tet), purified from a creeper Stephania tetrandra S Moore, is a bis-benzylisoquinoline alkaloid and has been used to treat patients with silicosis, autoimmune disorders, and hypertension in Mainland China for decades. The accumulated studies both in vitro and in vivo reveal that Tet preserves a wide variety of immunosuppressive effects. Importantly, the Tet-mediated immunosuppressive mechanisms are evidently different from some known DMARDs. The synergistic effects have also been demonstrated between Tet and other DMARDs like FK506 and cyclosporin. These results highlight Tet a very potential candidate to be considered as one of DMARDs in the treatment of autoimmune diseases, especially rheumatoid arthritis. This review summarizes evidence-based in vivo and in vitro studies on this potential Chinese immunosuppressive herb

Deregulation of interleukin-6 (IL-6) expression caused the synthesis and release of many inflammatory mediators. It is involved in chronic inflammation, autoimmune diseases, and malignancy. Stephania tetrandra S. Moore is a Chinese medicinal herb which has been used traditionary as a remedy for neuralgia and arthritis in China. To investigate the anti-inflammatory effects of S. tetrandra S. Moore in vitro and in vivo, its effects on the production of IL-6 and inflammatory mediators were analysed. When human monocytes/macrophages stimulated with silica were treated with 0.1-10 mug/ml S. tetranda S. Moore, the production of IL-6 was inhibited up to 50%. At these concentrations, it had no cytotoxicity effect on these cells. It also suppressed the production of IL-6 by alveolar macrophages stimulated with silica. In addition, it inhibited the release of superoxide anion and hydrogen peroxide from human monocytes/macrophages. To assess the anti-fibrosis effects of S. tetrandra S. Moore, its effects on in vivo experimental inflammatory models were evaluated. In the experimental silicosis model, IL-6 activities in the sera and in the culture supernatants of pulmonary fibroblasts were also inhibited by it. In vitro and in vivo treatment of S. tetrandra S. Moore reduced collagen production by rat lung fibroblasts and lung tissue. Also, S. tetrandra S. Moore reduced the levels of serum GOT and GPT in the rat cirrhosis model induced by CCL(4), and it was effective in reducing hepatic fibrosis and nodular formation. Taken together, these data indicate that it has a potent anti-inflammatory and antifibrosis effect by reducing IL-6 production.

Sinomenine, an antirheumatic alkaloid, ameliorates clinical signs of disease in the Lewis rat model of acute experimental autoimmune encephalolmyelitis.Zeng Y, Gu B, Ji X, Ding X, Song C, Wu F.
Department of Immunology, Nanjing Medical University, 140 Hanzhong Road, Nanjing 210029, China.
The therapeutic value of an antirheumatic alkaloid, sinomenine (SIN), was investigated in the acute experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis (MS). SIN is a bioactive alkaloid derived from the Chinese medicinal plant, Sinomenium acutum REHDER & E. H. WILSON (Family Menispermaceae). Chinese doctors have utilized this plant to treat rheumatic and arthritic diseases for over one thousand years. Experiments in which EAE-induced Lewis rats exhibit an acute monophasic episode of disease demonstrated that SIN is effective in preventing clinical signs of disease. The therapeutic effect on disease activity was observed at preonset administration times and at various doses tested. Consistent with disease activity in vivo, SIN-treated animals have reduced cellular infiltration within the spinal cord along with decreased TNF-alpha and IFN-gamma expression levels. SIN can significantly inhibit proliferation response of splenocytes induced by MBP(68-82). TNF-alpha and IFN-gamma, secreted by splenocytes induced by MBP(68-82) are inhibited by SIN by dose-dependence manner. The mRNA levels of CC chemokines, RANTES, MIP-1alpha and MCP-1, are inhibited in SIN-treated EAE rats. The data in this proof of concept study support the premise that SIN may be a promising new therapeutic intervention in MS.

Restoration of FcRgamma/Fyn signaling repairs central nervous system demyelination.Seiwa C, Yamamoto M, Tanaka K, Fukutake M, Ueki T, Takeda S, Sakai R, Ishige A, Watanabe K, Akita M, Yagi T, Tanaka K, Asou H.

Disruption of myelin causes severe neurological diseases. An understanding of the mechanisms that control myelination and remyelination is needed to develop therapeutic strategies for demyelinating diseases such as multiple sclerosis (MS). Our previous finding indicating the critical involvement of the gamma chain of immunogloblin Fc receptors (FcRgamma) and Fyn signaling in oligodendrocyte differentiaion and myelination demands a fundamental revision of the strategies used for MS therapy, because antigen-antibody complexes in MS patients may induce the direct dysregulation of myelination process as well as the inflammatory destruction of myelin sheath. Here we show that the FcRgamma/Fyn signaling cascade is critically involved in cuprizone-induced demyelination/remyelination, with no lymphocytic response. The levels of phosphorylated myelin basic proteins (p-MBPs), especially the 21.5-kDa isoform, but not the levels of total MBPs, decreased markedly during demyelination induced by aging, cuprizone treatment, and double knockout of FcRgamma/Fyn genes. We also showed that the recovery from demyelination in cuprizone-treated and aged mice is achieved after administration of the herbal medicine Ninjin'yoeito, an effective therapy targeting the FcRgamma/Fyn-Rho (Rac1)-MAPK (P38 MAPK)-p-MBPs signaling cascade. These results suggest that the restoration of FcRgamma/Fyn signaling represents a new approach for the treatment of demyelinating diseases. (c) 2007 Wiley-Liss, Inc.

Résumé / Abstract
The therapeutic effect of a traditional Chinese medicine ren-shen-yang-rong-tang (Japanese name: Ninjin'yoeito, NYT) on murine cytomegalovirus (MCMV)-associated pneumonitis was examined. In MCMV-pneumonitis, IFN-γ-induced nitric oxide (NO) mediates its pathogenesis. When mice, which had been infected with 0.2LD50 of MCMV at 28 days previously, were intraperitoneally injected with anti-CD3 monoclonal antibody (mAb), MCMV-pneumonitis was induced in the lung, where high amounts of IFN-γ-producing cells thereafter accumulated, accompanied by an elevation in the NO level in the serum and abundant expression of inducible NO synthase (iNOS) mRNA, thus resulting in all mice eventually dying. When the mice were orally treated with NYT (1000 mg/kg/day) once on the day of mAb injection and once the day after, the expression level of iNOS-mRNA was suppressed and NO level in the serum decreased. The survival rate improved from 0% to 57.1%. The pathological findings of the lungs in the NYT-treated mice were comparable to those of the uninfected controls. In contrast, NYT itself did not affect either the ratio of IFN-γ-producing cells or MCMV titer. As a result, NYT had a therapeutic effect on MCMV-pneumonitis by decreasing the degree of inflammation mediated by the IFN-γ-induced NO. It is also interesting to note that only two oral administrations of NYT had a therapeutic effect on viral disease.

Understanding of oligodendrocyte precursor cells and their role in the generation of oligodendrocytes in developing and adult rodents has been considered, particularly much less is known about aged-rodent oligodendrocyte precursor cells and their cell lineage. In this present study, we have developed oligodendrocyte cultures from the 30-month-old rat brain and examined whether oligodendrocyte precursor cells can proliferate in vitro. Adult oligodendrocyte precursor cells (O1−, O4+) and oligodendrocytes (O1+, O4+) are present in the cultures of the 30-month-old rat brain. They are also capable of proliferating and differentiating in the cultures. These capabilities increased four- to fivefold, when the aged rats are treated with Ninjin-Youei-To for 3 months in comparison with those of control aged rats. These results suggest that Ninjin-Youei-To has a potential mitotic effect on oligodendrocyte precursor cells in aged-rat brains and may be expected to have a therapeutic effect on brain aging.
