PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 119:155010. [PMID: 37586160 DOI: 10.1016/j.phymed.2023.155010] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 06/24/2023] [Accepted: 08/01/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND Not many drugs with fewer side effects are available for the treatment of rheumatoid arthritis (RA). Ganoderma lucidum polysaccharide peptide (GLPP) has good immunomodulatory effects, but whether it is effective in managing RA is not clear. PURPOSE This study was conducted to examine the anti-RA activity and possible mechanisms of GLPP in collagen-induced arthritis (CIA) rats. METHODS Male Wistar rats were intradermally injected with bovine type II collagen in the tail base to establish the CIA model and were orally administered 100 or 200 mg/kg GLPP for 35 days. Paw thickness, clinical arthritis scores, gait analysis, organ index determination, blood cell counts, micro-CT imaging and pathological staining were performed on the rats. Liver and kidney function were measured by commercial kits, and antibody levels were measured by ELISA kits. RA-related protein levels were detected by Western blotting. RESULTS GLPP effectively alleviated CIA symptoms and reduced immune organ indexes, antibody levels and systemic organ injury. GLPP decreased the protein expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, matrix metalloproteinase (MMP)2, MMP9, MMP13, BCL-2, OPN, β-Catenin, and hypoxia inducible factor (HIF)-1α and increased the protein expression of BAX in the joint tissues of CIA rats. Moreover, GLPP decreased the phosphorylation levels of p65, IκB-α and ERK1/2. CONCLUSION GLPP effectively alleviated RA symptoms in CIA rats by inhibiting the NF-κB and MAPK pathways. This study suggests a promising therapeutic effect of mushroom-derived polysaccharide peptides on RA.

Abstract
Rheumatoid arthritis (RA) is a chronic and autoimmune disease characterized by inflammation, autoimmune dysfunction, and cartilage and bone destruction. In this review, we summarized the available reports on the protective effects of Ganoderma lucidum polysaccharides (GLP) on RA in terms of anti-inflammatory, immunomodulatory, anti-angiogenic and osteoprotective effects. Firstly, GLP inhibits RA synovial fibroblast (RASF) proliferation and migration, modulates pro- and anti-inflammatory cytokines and reduces synovial inflammation. Secondly, GLP regulates the proliferation and differentiation of antigen-presenting cells such as dendritic cells, inhibits phagocytosis by mononuclear macrophages and nature killer (NK) cells and regulates the ratio of M1, M2 and related inflammatory cytokines. In addition, GLP produced activities in balancing humoral and cellular immunity, such as regulating immunoglobulin production, modulating T and B lymphocyte proliferative responses and cytokine release, exhibiting immunomodulatory effects. Thirdly, GLP inhibits angiogenesis through the direct inhibition of vascular endothelial cell proliferation and induction of cell death and the indirect inhibition of vascular endothelial growth factor (VEGF) production in the cells. Finally, GLP can inhibit the production of matrix metalloproteinases and promote osteoblast formation, exerting protective effects on bone and articular cartilage. It is suggested that GLP may be a promising agent for the treatment of RA.

Abstract
Development of drug products from natural sources enable advantageous treatment and therapy options. Bioactive compounds in Ganoderma lucidum spore powder (GLSP) are known for vast antibacterial, antioxidant and anti-cancer properties. Herein, we studied the use of dual-probe ultrasound to extract triterpenoids from GLSP and further investigated the bioactivity of resulting products. FTIR results confirm the presence of key peaks although dual-probe ultrasound varied extraction efficacy. Response surface methodology (RSM) was used to optimize extraction conditions (55:28 for solvent to solid ratio, 10.38 s of ultrasound time and 94% v/v of ethanol concentration). HPLC-Q-TOF-MS confirmed the presence of nine different compounds and in vitro tests confirm good biocompatibility. Extracts are shown to inhibit DPPH radicals, reaching a maximum (61.09 ± 1.38%) at triterpenoid concentrations of 600 µg/mL. Dual-mode assisted extraction provides an enhanced approach for active embedded fiber production on a scale favorable to industry when using optimized process parameters. Furthermore, triterpenoid extracts show antibacterial properties on Staphylococcus aureus and Escherichia coli with potential in antibacterial and anticancer applications.

Effect and Mechanism of Ganoderma lucidum Spores on Alleviation of Diabetic Cardiomyopathy in a Pilot in vivo Study. Diabetes Metab Syndr Obes 2020; 13:4809-4822. [PMID: 33335409 PMCID: PMC7736836 DOI: 10.2147/dmso.s281527] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Accepted: 11/25/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Ganoderma lucidum spores (GLS) exhibit disease prevention properties, but no study has been carried out on the anti-diabetic cardiomyopathy property of GLS. The aim of this study was to evaluate the hyperglycemia-mediated cardiomyopathy protection and mechanisms of GLS in streptozotocin (STZ)induced diabetic rats. METHODS Male SD rats were randomly divided into three groups. Two groups were given STZ (50 mg/kg, i.p.) treatment and when their fasting plasma glucose was above 16.7 mmol/L, among them, one group was given placebo, as diabetic group, and another group was given GLS (300 mg/kg) treatment. The group without STZ treatment was given placebo as a control group. The experiment lasted 70 days. The histology of myocardium and biomarkers of antioxidants, myocardial injury, pro-inflammatory cytokines, pro-apoptotic proteins and phosphorylation of key proteins in PI3K/AKT pathway were assessed. RESULTS Biochemical analysis showed that GLS treatment significantly reduced the blood glucose (-20.3%) and triglyceride (-20.4%) levels compared to diabetic group without treatment. GLS treatment decreased the content of MDA (-25.6%) and activity of lactate dehydrogenase (-18.9%) but increased the activity of GSH-Px (65.4%). Western blot analysis showed that GLS treatment reduced the expression of both alpha-smooth muscle actin and brain natriuretic peptide. Histological analysis on the cardiac tissue micrographs showed that GLS treatment reduced collagen fibrosis and glycogen reactivity in myocardium. Both Western blot and immunohistochemistry analyses showed that GLS treatment decreased the expression levels of pro-inflammatory factors (cytokines IL-1β, and TNF-α) as well as apoptosis regulatory proteins (Bax, caspase-3 and -9), but increased Bcl-2. Moreover, GLS treatment significantly increased the phosphorylation of key proteins involved in PI3K/AKT pathway, eg, p-AKT p-PI3K and mTOR. CONCLUSION The results indicated that GLS treatment alleviates diabetic cardiomyopathy by reducing hyperglycemia, oxidative stress, inflammation, apoptosis and further attenuating the fibrosis and myocardial dysfunction induced by STZ through stimulation of the PI3K/Akt/mTOR signaling pathway.

Abstract
The hard and indissolvable sporoderm of Ganoderma lucidum spore (GLS) hinders the release of bioactive components that are significant to disease treatment and vitality enhancement. In this paper, a strategy to break sporoderm was proposed, in which the chemical reaction was cooperated with physical actuation (ultrasonication and refrigeration). Dealing with this chemicophysical treatment, the porous sporoderm of GLS was formed, which was confirmed by scanning electron microscope (SEM). The effect factors and mechanism of breaking sporoderm were discussed, and the efficiency of breaking sporoderm was evaluated by detecting the dissolution behaviour of inner triterpenoids in GLS. In addition, aiming to improve the solubility and stability of GLS product, the β-cyclodextrin was used to seal the holes on sporoderm of GLS product. The results show that the developed method is effective and feasible in producing high-bioactive and stable GLS product.

Abstract
BACKGROUND Ganoderma lucidum (Lingzhi; LZ) and San-Miao-San (SMS) are Chinese medicines (CMs) used to treat inflammatory ailments and numbing syndrome/arthralgia syndrome (Bi Zheng), respectively. Given that the main symptoms of systemic lupus erythematosus (SLE) include inflammation of the joints, joint pain, edema and palpitations of the heart because of problems associated with Bi Zheng, it was envisaged that LZ and SMS could be used as potential treatments for this autoimmune disease. This study aims to investigate the anti-inflammatory activity of a combination formulation containing LZ and SMS (LZ-SMS) in SLE mice. METHODS Female adult Balb/c mice of 20-24 weeks of age were used as normal mice (n = 10), whereas female MRL/lpr mice of 12-24 weeks of age were divided into three groups (n = 10 in each group), including mild, moderate and severe SLE mice groups. The clinical characteristics of the SLE and Babl/c mice (i.e., body weight, joint thickness, lupus flare, proteinuria, leukocyturia and lymphadenopathy) were assessed. The plasma concentrations of anti-nuclear antibody (ANA) and anti-double stranded DNA antibody (anti-ds-DNA) were analyzed by an enzyme-linked immunosorbent assay, whereas the concentration of several key cytokines (IFN-γ, TNF-α, IL-6, IL-10, IL-2, IL-27, IL-12P70, IL-17A and IL-21) were analyzed by a Luminex multiplex assay. The gene expression profiles for differentiation of the T helper (Th) lymphocytes in splenic CD4(+) Th cells were assessed by RT-qPCR. Flow cytometry was used to measure the percentages of CD4(+)CD25(+)Foxp3(+) Treg cells and CD19(+)CD5(+)CD1d(+)IL-10(+) regulatory B (Breg) cells (IL-10(+) Bregs). RESULTS Concentrations of anti-ds-DNA in the plasma samples collected from the LZ-SMS-treated (500 mg/kg/day oral administration for 7 days followed with 50 mg/kg/day intraperitoneal administration for 7 days), moderate and severe SLE mice decreased significantly compared with the PBS treated mice (P < 0.05). The gene expression levels of the induced regulatory T (iTreg) and natural Treg (nTreg) cells were significantly higher than those of the Th17, Th1 and "conventional Th cells vs. Treg cells" regulated genes following the LZ-SMS treatment (P < 0.05). The percentages of CD4(+)CD25(+)Foxp3(+) Treg cells collected from the splenic, thymic and peripheral blood cells, as well as the percentages of IL-10(+) Bregs collected from the splenic and thymic cells increased significantly in the LZ-SMS-treated SLE mice (P < 0.05) compared with the untreated PBS group. The ratio of the percentage of CD4(+)CD25(+)Foxp3(+) Treg cells to the percentage of CD4(+)CD25(-) effector T cells collected from the splenic, thymic and peripheral blood cells in LZ-SMS-treated moderate and severe SLE mice increased significantly compared with the untreated PBS group (P < 0.05). Furthermore, a comparison with the PBS treatment group revealed significant decreases in the concentrations of several inflammatory cytokines, including IL-21, IL-10 and IL-17A (P < 0.05), as well as significant increases in the concentrations of IL-2 and IL-12P70 in the LZ-SMS treated SLE mice (P < 0.05). CONCLUSION LZ-SMS treatment led to significant increases in the percentages of CD4(+)CD25(+)Foxp3(+) Treg and IL-10(+) Breg cells, together with a reduction in the plasma concentrations of several inflammatory cytokines and the down-regulated expression of the corresponding cytokine related genes in SLE mice. The clinical characteristics of the LZ-SMS-treated SLE mice also improved significantly.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rheumatoid arthritis (RA) is a common worldwide public health problem. Traditional Chinese Medicine (TCM) achieved some results to some extent in the treatment of rheumatoid arthritis (RA). Especially in China, TCM formulas are used in the clinic because of their advantages. Some of these TCM formulas have been used for thousands of years in ancient China, they pays much attention to strengthening healthy qi, cleaning heat, and wet, activating blood, etc. So TCM in anti-RA drug is considered as a simple and effective method. In addition, TCM are also traditionally used as extracts and many Chinese herbs which are considered to be effective for RA. With the advancement of technologies and research methods, researchers have devoted themselves to exploring new therapeutic materials from troves of TCM. The components of TCM are identified and purified, which include alkaloids, coumarins, flavonoids, saponins and so on. However, little or no review works are found in the research literature on the anti-RA drugs from TCM. The present review aims to provide systematically reorganized information on the ethnopharmacology, phytochemistry and pharmacology of TCM used traditionally against RA. The information recorded in this review will provide new directions for researchers in the future. MATERIALS AND METHODS Relevant scientific literatures were collected from Chinese traditional books and Chinese Pharmacopoeia. Several important pharmacology data, clinical observations, animal experiments on effects of anti-RA drugs from TCM and their mechanisms were extracted from a library and electric search (Pubmed, PubChem Compound, Science Direct, Spring Link, Elsevier, Web of Science, CNKI, Wan Fang, Bai du, The Plant List, etc.). We collected information published between 2002 and 2015 on Chinese medicine in the treatment of RA. Information was also acquired from local classic herbal literature, conference papers, government reports, and PhD and MSc dissertations. RESULTS This review mainly introduces the current research on anti-RA TCM formulas, extracts and compounds from TCM, pharmacological data and potential mechanisms (inhibit osteoclast proliferation, suppress fibroblast-like synoviocytes (FLSs) growth, decrease the expression of inflammatory cytokines, blocking signal pathways, etc.). CONCLUSIONS TCM, as a multi-component and multi-target approach, which is a perfect match with the holistic concept of systems biology, is applicable in the treatment of RA. The synergistic connections of Chinese herbs and mechanisms of related active compounds on RA increase the trust for TCM. TCM as alternative remedies for RA not only has an important position in the world market, but also has an irreplaceable role in the treatment of RA in future.

Ganoderma lucidum polysaccharide peptide prevents renal ischemia reperfusion injury via counteracting oxidative stress. Sci Rep 2015; 5:16910. [PMID: 26603550 PMCID: PMC4658483 DOI: 10.1038/srep16910] [Citation(s) in RCA: 52] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2015] [Accepted: 10/21/2015] [Indexed: 12/03/2022] Open
Abstract
Ganoderma lucidum polysaccharide peptide (GLPP) scavenges oxygen free radicals
that are a key factor in the pathogenesis of renal ischemia reperfusion injury
(RIRI). The aim of this study was to determine whether GLPP could attenuate RIRI by
counteracting the oxidative stress. The mechanism involved was assessed by an in
vivo mouse RIRI model and an in vitro hypoxia/reoxygenation model,
and tunicamycin-stimulated NRK-52E cells were used to explore the GLPP-mediated
alleviation of ER stress. Experimental results showed that renal dysfunction and
morphological damage were reduced in GLPP-treated group. The imbalance of redox
status was reversed and production of ROS was reduced by GLPP. RIRI-induced
mitochondrial- and ER stress-dependent apoptosis were dramatically inhibited in
GLPP-treated group. Intriguingly, JNK activation in the kidney with RIRI or
hypoxia/reoxygenation was inhibited by GLPP. These results suggest that the
protective effect of GLPP against RIRI may be due to reducing oxidative stress,
alleviating the mitochondrial and ER stress-dependent apoptosis caused by excessive
ROS.

Abstract
AIM This study aimed at evaluating the anti-microbial activity of spore powder of Ganoderma lucidum on Prevotella intermedia isolated from subgingival plaque from chronic periodontitis patients. SETTINGS AND DESIGN Written informed consent was obtained from each subject enrolled in the study. The Institutional Ethics Committee granted the ethical clearance for the study. MATERIALS AND METHODS This study included 20 patients diagnosed with chronic periodontitis. Pooled subgingival plaque samples were collected using sterile curettes from the deepest sites of periodontal pockets. The collected samples were then transported in 1 mL of reduced transport fluid. The organisms were cultured and confirmed. These organisms were then used for minimum inhibitory concentration (MIC) procedure. STATISTICAL ANALYSIS Mean of the MIC value obtained was calculated. RESULTS Thirteen out of the 20 clinical samples were tested that showed sensitivity at various concentrations. Five samples showed sensitivity at all concentrations. Twelve samples showed sensitivity at 8 mcg/ml. Eleven samples showed sensitivity at 4 mcg/ml, 8 samples showed sensitivity at 2 mcg/ml, and 5 samples showed sensitivity even at 1 mcg/ml. Mean MIC value of G. lucidum spore powder for P. intermedia obtained was 3.62 mcg/ml. CONCLUSION G. lucidum with its multipotential bioactivity could be used as an anti-microbial, in conjunction with conventional therapy in periodontal disease.

Ganoderma lucidum Polysaccharides Reduce Lipopolysaccharide-Induced Interleukin-1 β Expression in Cultured Smooth Muscle Cells and in Thoracic Aortas in Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:305149. [PMID: 24723958 PMCID: PMC3960732 DOI: 10.1155/2014/305149] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/12/2013] [Revised: 01/07/2014] [Accepted: 01/28/2014] [Indexed: 11/18/2022]
Abstract
The expression of inflammatory cytokines on vascular walls is a critical event in vascular diseases and inflammation. The aim of the present study was to examine the effects of an extract of Ganoderma lucidum (Reishi) polysaccharides (EORPs), which is effective against immunological disorders, on interleukin- (IL-) 1β expression by human aortic smooth muscle cells (HASMCs) and the underlying mechanism. The lipopolysaccharide- (LPS-) induced IL-1β expression was significantly reduced when HASMCs were pretreated with EORP by Western blot and immunofluorescent staining. Pretreatment with 10 μg/mL EORP decreased LPS-induced ERK, p38, JNK, and Akt phosphorylation. But the increase in IL-1β expression with LPS treatment was only inhibited by pretreatment with the ERK1/2 inhibitor, while the JNK and p38 inhibitors had no effect. In addition, EORP reduced the phosphorylation and nuclear translocation of nuclear factor- (NF-) κB p65 in LPS-treated HASMCs. Furthermore, in vivo, IL-1β expression was strongly expressed in thoracic aortas in LPS-treated mice. Oral administration of EORP decreased IL-1β expression. The level of IL-1β expression in LPS-treated or in LPS/EORP-treated group was very low and was similar to that of the saline-treated group in toll-like receptor 4-deficient (TLR4−/−) mice. These findings suggest that EORP has the anti-inflammatory property and could prove useful in the prevention of vascular diseases and inflammatory responses.

Abstract
The fatigue prevalence in breast cancer survivors is high during the endocrine treatment. However, there are few evidence-based interventions to manage this symptom. The aim of this study was to investigate the effectiveness of spore powder of Ganoderma lucidum for cancer-related fatigue in breast cancer patients undergoing endocrine therapy. Spore powder of Ganoderma lucidum is a kind of Basidiomycete which is a widely used traditional medicine in China. 48 breast cancer patients with cancer-related fatigue undergoing endocrine therapy were randomized into the experimental or control group. FACT-F, HADS, and EORTC QLQ-C30 questionnaires data were collected at baseline and 4 weeks after treatment. The concentrations of TNF-α, IL-6, and liver-kidney functions were measured before and after intervention. The experimental group showed statistically significant improvements in the domains of physical well-being and fatigue subscale after intervention. These patients also reported less anxiety and depression and better quality of life. Immune markers of CRF were significantly lower and no serious adverse effects occurred during the study. This pilot study suggests that spore powder of Ganoderma lucidum may have beneficial effects on cancer-related fatigue and quality of life in breast cancer patients undergoing endocrine therapy without any significant adverse effect.

Abstract
BACKGROUND The functional role of dietary carbohydrates in nutrition is one of the most complex and at times controversial areas in nutritional science. In-vitro and in-vivo studies suggest that certain dietary saccharide biopolymers can have bifidogenic and or immunomodulatory effects, and that some could represent preferential substrates or precursors that can impact cellular glycosylation. OBJECTIVE Examine the impact of oral ingestion of a standardized dietary plant-derived polydisperse polysaccharide supplement (Advanced Ambrotose powder (AA)) on the N-glycosylation status of serum glycoproteins in a cohort of healthy individuals. DESIGN An open-label study was carried out. This study was in two phases: pilot study (n=6 individuals) to assess safety and dose, and a larger study (n=12) to evaluate specific glycosylation changes. Serum N-glycosylation profiles, using mass spectrometry, were monitored at weekly intervals, for 7 weeks, to evaluate baseline levels and normal fluctuations. The individuals were then monitored for a further 7 weeks, during which time increasing doses of AA were ingested (1.3-5.2 g/day). RESULTS No adverse events were encountered. AA supplementation resulted in distinct changes in the relative intensities of seven biantennary N-glycans (P<0.001), and a significant overall shift towards increased sialylation. Regression analysis revealed a dose-dependent decrease in mono- and di-galactosylated structures (coefficient -0.130 decrease/week: P=0.02 and -0.690: P=0.005), and a concomitant increase in disialylated glycans ( × 1.083: P<0.05). CONCLUSIONS Supplementation with the dietary plant-derived polysaccharides in AA resulted in significant changes in serum protein N-glycosylation in healthy individuals. How this occurs and whether it has biological significance remains to be evaluated.

Abstract
BACKGROUND A large body of literature suggests that certain polysaccharides affect immune system function. Much of this literature, however, consists of in vitro studies or studies in which polysaccharides were injected. Their immunologic effects following oral administration is less clear. The purpose of this systematic review was to consolidate and evaluate the available data regarding the specific immunologic effects of dietary polysaccharides. METHODS Studies were identified by conducting PubMed and Google Scholar electronic searches and through reviews of polysaccharide article bibliographies. Only articles published in English were included in this review. Two researchers reviewed data on study design, control, sample size, results, and nature of outcome measures. Subsequent searches were conducted to gather information about polysaccharide safety, structure and composition, and disposition. RESULTS We found 62 publications reporting statistically significant effects of orally ingested glucans, pectins, heteroglycans, glucomannans, fucoidans, galactomannans, arabinogalactans and mixed polysaccharide products in rodents. Fifteen controlled human studies reported that oral glucans, arabinogalactans, heteroglycans, and fucoidans exerted significant effects. Although some studies investigated anti-inflammatory effects, most studies investigated the ability of oral polysaccharides to stimulate the immune system. These studies, as well as safety and toxicity studies, suggest that these polysaccharide products appear to be largely well-tolerated. CONCLUSIONS Taken as a whole, the oral polysaccharide literature is highly heterogenous and is not sufficient to support broad product structure/function generalizations. Numerous dietary polysaccharides, particularly glucans, appear to elicit diverse immunomodulatory effects in numerous animal tissues, including the blood, GI tract and spleen. Glucan extracts from the Trametes versicolor mushroom improved survival and immune function in human RCTs of cancer patients; glucans, arabinogalactans and fucoidans elicited immunomodulatory effects in controlled studies of healthy adults and patients with canker sores and seasonal allergies. This review provides a foundation that can serve to guide future research on immune modulation by well-characterized polysaccharide compounds.

Abstract
The expression of adhesion molecules on vessels and subsequent leukocyte recruitment are critical events in vascular diseases and inflammation. The aim of the present study was to examine the effects of an extract of Ganoderma lucidum (Reishi) polysaccharides (EORP), which is effective against cancer and immunological disorders, on adhesion molecule expression by human aortic smooth muscle cells (HASMCs) and the underlying mechanism. EORP significantly suppressed lipopolysaccharide (LPS)-induced intercellular cell adhesion molecule-1 (ICAM-1) mRNA and protein expression and reduced the binding of human monocytes to LPS-stimulated HASMCs. Immunoprecipitation and real-time polymerase chain reaction demonstrated that EORP markedly reduced the interaction of human antigen R protein (HuR) with the 3'-UTR of ICAM-1 mRNA in LPS-stimulated HASMCs. EORP treatment also suppressed extracellular signal-regulated kinase (ERK) phosphorylation and reduced the density of the shifted bands of nuclear factor (NF)-kappaB after LPS-induced activation. In an endothelial-denuded artery model in LPS-treated mice, daily oral administration of EORP for 2 weeks decreased neointimal hyperplasia and ICAM-1 expression in the plasma and neointima. These results provide evidence that EORP attenuates LPS-induced adhesion molecule expression and monocyte adherence and that this protective effect is mediated by decreased ERK phosphorylation and NF-kappaB activation. These findings suggest that EORP has anti-inflammatory properties and could prove useful in the prevention of vascular diseases and inflammatory responses.

Abstract
Spores of Ganoderma lucidum contain a large amount of bioactive substances and have a higher bioactivity than the fruit bodies of G. lucidum. However, ingredients from spores are less studied due to the difficulties in collecting the spores and breaking the rigid shell. In this study, a water-soluble polysaccharide named GSG was extracted from the spores of G. lucidum. GSG is characterized to be a branched glucan that contains several different kinds of linkages. It was an effective inducer of MAPKs- and Syk-dependent TNF-alpha and IL-6 secretion in murine resident peritoneal macrophages. Dectin-1 could recognize GSG and partially mediate its biological activities. Additionally, in vivo administration of GSG potentiated the Con A-induced proliferative response of splenocytes and induced anti-tumor activity against Lewis lung cancer in mice. Therefore, these results suggest that GSG is an effective immunomodulator and may be a promising adjuvant remedy for anti-tumor therapies.

Abstract
AIM OF STUDY In this study, we have investigated the analgesic and anti-arthritic effects of a traditional Chinese medicine (TCM) combination of Lingzhi and San Miao San (SMS) in a rat model of arthritis induced by Freund's complete adjuvant (FCA). MATERIALS AND METHODS Sprague-Dawley rats were induced with monoarthritis by single unilateral injection of FCA into the knee joint. The TCM combination was administered to the rats daily by intraperitoneal injection (50mg/(kgday)) or via oral administration (500mg/(kgday)) for 7 days before induction of arthritis and 7 days after. Extension angle that provoked struggling behavior, and size and blood flow of the rat knees were measured to give indexes of allodynia, edema, and hyperemia, respectively. The extent of cell infiltration, tissue proliferation, and erosions of joint cartilage provided additional indexes of the arthritis condition. RESULTS FCA injection produced significant allodynia, edema, hyperemia, immune cell infiltration, synovial tissue proliferation, and erosions of joint cartilage in the ipsilateral knees compared with the contralateral saline-injected knees. Intraperitoneal injection of the TCM combination (50mg/(kgday)) suppressed allodynia, edema, and hyperemia in the inflamed knees, and oral administration (500mg/(kgday)) suppressed edema and hyperemia. Histological examination showed that the TCM administered by either route reduced immune cell infiltration and erosion of joint cartilage. CONCLUSIONS These findings suggest the Lingzhi and SMS formulation has analgesic and anti-inflammatory effects in arthritic rat knees, and concur to previous clinical studies that showed the TCM combination reduced pain in rheumatoid arthritis patients, and extends its possible benefit to suppression of inflammatory symptoms in these patients.
