Evaluation of cosmetic efficacy of lychee seed fermentation liquid

BackgroundLychee seeds were fermented by three kinds of bacteria (Lactobacillus plantarum, Saccharomyces cerevillus and ganoderma lucidum mycelium), and two effective strains were selected by two indexes of activity content and antioxidant, so as to further verify whether lychee seeds have waste multiplication effect and can protect cells damaged by oxidation from anti-inflammatory, anti-aging and safety.ResultsThe contents of polyphenols, flavonoids and proteins in the solution fermented by Ganoderma lucidum mycelium did not increase, thus affecting the antioxidant capacity of the solution was far less than that of the water extract. The active content of the other two fermentation solutions was higher than that of the water extract, and the ability of scavenging free radicals of the two solutions increased with the increase of the volume fraction. At the cellular level, the two fermentation solutions showed repair effects on UVA-induced damaged cells. The contents of type I collagen (COL-1), total antioxidant capacity and ELN were increased, the contents of reactive oxygen species and MDA were decreased, and the expressions of inflammatory factors IL-6, TNF-a, iNOS and COX-2 were decreased in HaCaT cells. From the gene level, the mRNA contents of IL-6, TNF-a, Caspase-3, Caspase-9, Bax and Bcl were significantly decreased. The test of chick embryo chorioallantoic membrane (HTET CAM) showed that there was no bleeding and litchi seed fermentation liquid was not irritating.ConclusionsTherefore, two kinds of litchi seed fermentation can be used as natural plant raw materials for cosmetics, and have strong antioxidant, anti-inflammatory and anti-aging functions on skin, and also have good human safety.Graphical

High performance biochar derived from mycelium-based leather composites waste for energy storage applications

The mycelial waste generated during the production of mycelium-based leather composites presents both opportunities and challenges in maximizing biomass resource efficiency. In this study, we synthesized mesoporous biochar (AGLM-5) with a specific surface area of 3151.9 m2/g through the KOH activation method using Ganoderma lucidum mycelium waste as the precursor material. AGLM-5 exhibited exceptional performance in a three-electrode system test, demonstrating a specific capacitance of 303.5 F/g. In a two-electrode system test, it achieved an energy density of 45.5 Wh/kg at a power density of 450.7 W/kg. The symmetric supercapacitor assembled using AGLM-5 demonstrated outstanding cycling stability over 10,000 cycles, exhibiting a capacitance loss of less than 4 % throughout the entire testing period. Additionally, we employed a hydrothermal method to synthesize composite electrode sheets (δ-MnO2/AGLM-5), which not only supported the layered structure of δ-MnO2 but also significantly improved the cycling stability and electrical conductivity of aqueous zinc ion batteries (AZIB). This study presents an environmentally friendly and sustainable approach for utilizing Ganoderma lucidum mycelial biomass, with particular emphasis on the potential application of mycelial carbon materials in battery energy storage.

Treatment of the Textile Wastewater using Malaysian Ganoderma lucidum Mycelial Pellets

Purification of textile wastewater using biomass and in particular different fungi is gaining exponential interest to minimize the impacts of current physical-chemical and biological wastewater treatment by-products. This study investigates the potential of Malaysian Ganoderma lucidum mycelium pellets (GLMP) for the decontamination of wastewater samples received from a commercial textile manufacturer. All studies were performed under ambient temperature (26-35 ℃) and unsterilized conditions using a simple bioreactor design (stirred batch bioreactor) for a more practical assimilation of the current available wastewater treatment process system. The optimal conditions of adsorption by GLMP were determined by variation effects of adsorbent concentration (0, 8.75, 12.5 and 25 g/L), pH (unadjusted 7.10 – 8.22, 4 and 6), and wastewater dilution factor (1:0, 1:4, and 2:3, v/v). This method was proved to be effective in both decolorization and chemical oxygen demand (COD) reduction, simultaneously. The most significant percentage of decolorization observed was 77.24% in a 72 h treatment, whereas COD reductions were 78.32% in a 36 h treatment. The present study fits both Langmuir and Freundlich adsorption isotherms as the values of R2 both model were close to 1, indicating the favorable adsorption of dyes towards Malaysian GLMP.

Temporal dynamics of lignin degradation in Quercus acutissima sawdust during Ganoderma lucidum cultivation

Despite a fair amount of lignin conversion during mycelial growth, previous structural analyses have not yet revealed how lignin changes continuously and what the relationship is between lignin and ligninolytic enzymes. To clarify these aspects, Quercus acutissima sawdust attaching Ganoderma lucidum mycelium collected from different growth stage was subjected to analysis of lignin structure and ligninolytic enzyme activity. Two key periods of lignin degradation are found during the cultivation of G. lucidum: hypha rapid growth period and primordium formation period. In the first stage, laccase activity is associated with the opening of structures such as methoxyls, β-O-4′ substructures and guaiacyl units in lignin, as well as the shortening of lignin chains. Manganese peroxidases and lignin peroxidases are more suitable for degrading short chain lignin. The structure of phenylcoumarans and syringyl changes greatly in the second stage. The results from sawdust attaching mycelium provide new insights to help improve the cultivation substrate formulation of G. lucidum and understand biomass valorization better.

The Triterpenoid High-Performance Liquid Chromatography Analytical Profiles of the Mycelia of Ganoderma lucidum (lingzhi)

(1) Background: Ganoderic acids (GAs) are specific triterpenes of Ganoderma lucidum. The HPLC fingerprint profile of GAs of the fruiting body is well known, but their mycelial fingerprinting remains unclear. (2) Methods: An ethanol extract of the mycelium of G. lucidum (YK-01) was further purified via preparative HPLC. The triterpenoid compositions for four strains of G. lucidum and one strain of G. formosanum (purple lingzhi) were analyzed using HPLC. (3) Results: Nineteen lanostane triterpenes, including five new triterpenes, GA-TP (1), ganodermic acid Jc (GmA-Jc) (2), GmA-Jd (3), GA-TQ1 (4), and ganoderal B1 (5), and fourteen known triterpenes 6–19 were isolated from the ethanol extract. Their structures were identified by mass and extensive NMR spectroscopy. A green chemical HPLC analytical method was developed using ethanol and acetic acid as a mobile phase, and all isolated compounds can be well separated. These triterpenes comprise a unique HPLC chromatograph of the G. lucidum mycelium. All four G. lucidum strains showed the same HPLC chromatographic pattern, whereas G. formosanum displayed a different pattern. Quantitation methods for ganoderic acid T (10) and S (12) were also validated. (4) Conclusions: The triterpenoid HPLC analytical method can be used to identify the G. lucidum species and to determine the contents of GA-T and GA-S.

Significance of culture period on the physiochemistry and anti-cancer potentials of polysaccharides from mycelia of Ganoderma lucidum

Ganoderma lucidum polysaccharides (GPS) have many functions. Polysaccharides are abundant in G. lucidum mycelia, but it is unclear whether the production and chemical characteristics of polysaccharides are related to the liquid cultural periods of mycelia. This study harvests G. lucidum mycelia at different cultural stages and isolates GPS and sulfated polysaccharides (GSPS) separately to determine an optimum cultural duration. After 42 and 49 days of mycelia are found to be the best times to harvest GPS and GSPS. Characteristic studies show that glucose and galactose are the main sugars in GPS and GSPS. The molecular weights of various GPS and GSPS are mainly distributed at >1000 kDa and from 101 to 1000 kDa. The sulfate content of GSPS at Day 49 is greater than that at Day 7. GPS and GSPS at 49 days exhibits a good anticancer effect but does not affect normal fibroblasts. GPS and GSPS that is isolated on day 49 inhibits lung cancer by suppressing epidermal growth factor receptor (EGFR) and transforming growth factor beta receptor (TGFβR)-mediated signaling networks. These results show that the mycelia of G. lucidum that are cultured for 49 days exhibit the best biological characteristics.

Ganoderma lucidum polysaccharides improve lipid metabolism against high-fat diet-induced dyslipidemia.

As a kind of traditional medicinal fungi, Ganoderma lucidum has been employed as folk medicine in China against multiple metabolic diseases on account of its superior bioactivities. Recently, accumulated reports have investigated the protective effects of G. lucidum polysaccharides (GLP) on ameliorating dyslipidemia. However, the specific mechanism by which GLP improves dyslipidemia is not completely clear. This study aimed to investigate the protective effects of GLP on high-fatdiet-induced hyperlipidemia and exploring its underlying mechanism. The GLP was successfully obtained from G. lucidum mycelium. The mice were conducted with high-fatdiet to establish the hyperlipidemia model. Biochemical determination, histological analysis, immunofluorescence, western blot and real-time qPCR were used to assess the alterations in high-fatdiet-treated mice after the GLP intervention. It was found that GLP administration significantly decreased body weight gain and the excessive lipid levels, and partly alleviated tissue injury. Oxidative stress and inflammations were efficiently ameliorated after the treatment of GLP by activing Nrf2-Keap1 and inhibiting NF-κB signal pathways. GLP promoted cholesterol reverse transport by LXRα-ABCA1/ABCG1 signaling, increased the expressions of CYP7A1 and CYP27A1 responsible for bile acids production, accompanied by inhibition of intestinal FXR-FGF15 levels. Besides, multiple target proteins involved in lipid metabolism were also significantly modulated under the intervention of GLP. Taken together, our results suggested that GLP showed potential lipid-lowering effects and its possible mechanism was involved in improving oxidative stress and inflammation response, modulating bile acids synthesis and lipid regulatory factors, and promoting reverse cholesterol transport, thereby suggesting that GLP may possibly used as a dietary supplement or medication for the adjuvant therapy for hyperlipidemia.

영지버섯 균사체 발효 꾸지뽕 잔가지 추출물의 3T3-L1 지방전구세포 분화 억제 및 항염증 효과

This study aimed to evaluate the anti-adipogenic and anti-inflammation effects of extract from Maclura tricuspidata twig fermented with Ganoderma lucidum mycelium (EMFG) in 3T3-L1 preadipocytes. 3T3-L1 adipocytes were treated with 100, 200, 300 μg/mL of EMFG. The result showed that EMFG dose-dependently inhibited the accumulation of intracellular lipid content in differentiated 3T3-L1 adipocytes and enhanced increase of adiponectin release and inhibition of leptin release. EMFG treatment reduced expression of adipogenic transcriptional factor such as peroxisome proliferator-activated receptor γ (PPARγ), CCAAT-enhancer-binding protein α (C/EBPα). EMFG also decreased production of lipopolysaccharide (LPS)-induced inflammatory cytokine [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1)] and the protein expression of cyclooxygenase-2 (COX-2) and inducible NOS (iNOS) in differentiated 3T3-L1 adipocytes. The study demonstrated that EMFG inhibited adipogenesis and inflammation in a dose-dependent manner. These findings suggest that EMFG may have potential as an anti-obesity and anti-metabolic disease agent that works by inhibiting adipogenesis and inflammation.

Combination Treatment in Ulcerative Colitis using 5-Aminosalysilic Acid (5-ASA) and Polysaccharide Peptide of Indonesian Ganoderma lucidum Mycelium Extract

Background: Inflammatory bowel disease (IBD) is idiopathic disease characterized by chronic inflammation of the gastrointestinal tract. Polysaccharide peptide of Ganoderma lucidum mycelium extract (PPGL) is considerably a good option for adjunctive therapy of IBD. This study aims to evaluate the benefit of PPGL in patients treated with 5-ASA.Method: A retrospective observational cohort study was conducted to examine the medical records of 124 ulcerative colitis patients. There were 80 patients in intervention group who were treated with a combination of 5-ASA and PPGL, and there were 44 patients in the control group who were treated with 5-ASA only. Clinical and laboratory endpoints were observed at the baseline and after 30, 60, and 90 days. Clinical endpoints included abdominal pain, bloody diarrhea, aphthous stomatitis, and polyarthritis; meanwhile, laboratory endpoints included hemoglobin level, ESR, CRP, fecal calprotectin, M2-pyruvate kinase (MP2K), fecal culture, C. difficile culture, and colonoscopy results. Clinical trials conducted after patient enrollment with registry number ClinicalTrials.gov NCT04029649.Results: On day-30 there was a significant difference between intervention group 45.6% and control group 2.3% in abdominal pain complaints (p 0.001). Moreover, laboratory parameters of fecal calprotectin (p 0.001), fecal MP2K (p = 0.015), and hemoglobin (p 0.001) were considerably better in intervention group on day-30. These differences were consistently found on day 60 and 90.Conclusion: The study implies potential correlation between PPGL administration and improvement of clinical and laboratory endpoints up to 90 days. A larger randomized, blinded, prospective study is required to confirm these effects in ulcerative colitis.

Effects of manganese, sodium nitrate, and ammonium nitrate on the growth rate of Ganoderma lucidum mycelium

Features of the Formation of Sensitive Films Based on Mycelium of Higher Fungi for Surface and Plate Acoustic Waves Gas Sensors.

A comparative analysis of the responses of two types of acoustic waves (surface SAW and plate APW) with close frequencies and the same type of waves (SAW) with different frequencies toward various liquid vapors (water, acetone, ethanol) was carried out in this paper. Two types of films based on mycelium of higher fungus Ganoderma lucidum (Curtis) P. Karst (G. lucidum) prepared by various methods were used as sensitive coatings. These films were based on G. lucidum mycelium ethanolic (48% v/v) homogenizate (MEGl) and extract (EGl). A film deposition procedure compatible with acoustic devices technology was developed. Various piezoelectric substrates (YX-LiNbO3, 128 YX-LiNbO3) were used for appropriate acoustic delay lines production. It was found that additional SAW and APW attenuation associated with the appearance of mycelium films on the surface of the acoustic waveguide is two times greater for MEGL than for EGL films in the frequency range of 20-80 MHz The changes in acoustic wave amplitude and phase due to vapor absorption were measured and compared with each other, taking into account the differences in geometry of the samples. It was found that the phase response of the SAW delay lines with EGL films is three times higher than one with the presence of MEGL films for water and ethanol vapors. The films used are demonstrated good reproducibility and long-term stability for at least 2 months. Based on the results obtained, it was concluded that MEGl film is not appropriate for use in high frequency SAW delay lines as a sensitive coating. However, both types of the films (MEGl and EGl) could be used as sensitive coatings for low frequency SAW and APW sensors based on corresponding delay lines. Additionally, it was found that the films used are not sensitive to acetone vapor. As a result of the work carried out, a technique for creating sensitive films based on the mycelium of higher fungi compatible with the planar technology of acoustoelectronic delay lines was developed. The possibility of using such films for the development of gas SAW and APW sensors was shown.

Bioactivity of Ganoderma lucidum and optimization of mycelial fermentation conditions

Ganoderma lucidum is a very precious traditional Chinese medicine. It has good pharmacological effects because of its polysaccharides, triterpenoids and other biological activities. Ganoderma lucidum mycelium is rich in Ganoderma lucidum polysaccharides and other substances, but it is difficult to obtain under natural conditions, so it is generally obtained through artificial inoculation or fermentation. Therefore, it is imperative to optimize the mycelium fermentation conditions. The range of fermentation time, temperature and pH of response surface analysis was determined by single factor experiment. The optimal fermentation conditions were fermentation temperature 28℃, pH=7, fermentation time 7 days, and mycelium biomass of (7±0.1) g/L. The results provide data reference for better utilization and development of Ganoderma lucidum.

Ganoderma lucidum mitigates gamma radiation-induced oxidative stress in Swiss albino mice

ObjectiveRadiotherapy is well established in cancer therapeutics. Though radiation targets tumor cells, they damage normal tissues by bystander effect. The present study aimed to evaluate the radioprotective efficacy of Ganoderma lucidum (GL) mycelium powder on gamma radiated swiss albino mice. Materials and methodQualitative phytochemical tests and in-vitro antioxidant activity of GL were carried out using standard protocols. Institutional animal ethical committee clearance was obtained. The pre and post-treated mice were irradiated using Gamma chamber 2000 (CARRT), Mangalore University. Biochemical estimations (TAC, SOD, NO, GPx, MDA, reduced glutathione), hematological markers (RBC, WBC, Hb, Platelet), lipid profile, inflammatory markers (Il-2, TNF-alpha, IF-gamma) and genotoxic markers (micronucleus and comet assay) were performed using standard protocols and commercially available kits. ConclusionThe pre and post-treatment groups showed statistically significant differences (p < 0.05) compared to radiation control in hematological parameters, lipid profile, micronucleus, and comet formation. In pre-treatment and post-treatment groups, Ganoderma lucidium mycelium extracts mitigated radiation-induced hematological, oxidative stress, hyperlipidemia, and genotoxic changes.

The potential beneficial effects of polysaccharide peptide on oxidative stress and lipid profile in post myocardial infarction patients: a double-blind, randomised controlled trial

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Indonesia"s Ministry of Research and Technology grants Background Inflammation, oxidative stress and lipid peroxidation activities contribute to the progression of atherosclerosis leading to myocardial infarction (MI). These sustainable cascade are considered to remain, in fact after the episode of MI. Polysaccharide peptide is renowned to exert anti-oxidative and lipid-lowering effects, thus may impair subsequent post-infarction plaque accumulation. Purpose To evaluate the role of polysaccharide peptide of Ganoderma lucidum mycelium extracts (β-1,3/1,6-D-Glucan) as potent protective antioxidant and lipid-lowering agent in post MI patients. Methods This was a prospective, double-blind, placebo-controlled, randomised clinical trial in 45 post MI patients who had undergone reperfusion or conservative therapy. The eligible and consenting patients were randomly assigned (1:1 ratio) into two groups i.e. treated group (TG) and control group (CG). Treated group was given 180 mg β-1,3/1,6-D-Glucan thrice a day for 90 days, and control group received placebo. Variables measured were nitric oxide (NO), superoxide dismutase (SOD), malondialdehyde (MDA), plasma total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides. All measurements were conducted at baseline and after 90-days. All patients received guideline-driven therapy throughout the study. Results There was no significant difference in the baseline characteristics between the two groups (all p &amp;gt; 0.05). At 90 days, allocation to polysaccharide peptide demonstrated significant increase in NO and SOD (p = 0.020, p = 0.023; respectively) and also significant reduction in MDA (p = 0.001) as compared to placebo. Treated group compared with placebo revealed significant reduction in LDL-C (p = 0.036), but not in total cholesterol, HDL-C and triglycerides (p = 0.105, p = 0.398, p = 0.843; respectively). Conclusions Polysaccharide peptide exhibits potent protective anti-oxidative and lipid-lowering properties in post MI patients. It may offer benefit on top of standard medical treatment.

The Role of β-1.3/1.6-D-Glucan From Ganoderma lucidum Mycelium Extract in Ulcerative Colitis

Ulcerative colitis (UC) is an idiopathic inflammatory disease that affects the colon. Current pharmacological modalities to treat UC have various side effects; therefore, there is a demand to develop a new alternative medicine that can reduce side effects and increase drug efficacy. One candidate for alternative therapy is Polysaccharide Peptide which is extracted from Ganoderma lucidum mycelium. This Polysaccaharide has an active compound of Β-1,3/1,6-D-Glucan which has strong immunomodulatory and anti-inflammatory properties. Various studies have reported that Ganoderma lucidum polysaccharides can reduce inflammatory markers such as TNF-α, IFN-γ, and IL-17A, which is produced by colonic mucosal inflammation. In addition, β-1,3/1,6-D-Glucan has shown improvements in inflammatory parameters and intestinal immunological barrier function animal studies with artificial colitis and requires further research in humans before clinical applications.

Mechanical properties of dense mycelium-bound composites under accelerated tropical weathering conditions

Mycelium, as the root of fungi, is composed of filamentous strands of fine hyphae that bind discrete substrate particles into a block material. With advanced processing, dense mycelium-bound composites (DMCs) resembling commercial particleboards can be formed. However, their mechanical properties and performance under the working conditions of particleboards are unknown. Here, we show how weathering conditions affect the DMC stress and elastic modulus. DMC was made using Ganoderma lucidum mycelium grown on a substrate of sawdust and empty fruit bunch. The DMC was then subjected to weathering under tropical conditions over 35 days and tested under flexural, tensile, and compressive loading with reference to international standards. After exposure to specified weathering conditions, the maximum stress in flexure, tension, and compression decreased substantially. The addition of a protective coating improved the resistance of DMC to weathering conditions; however, the difference between coated and uncoated samples was only found to be statistically significant in tensile strength.

Effect of Pretreated Colza Straw on the Growth and Extracellular Ligninolytic Enzymes Production by Lentinula edodes and Ganoderma lucidum

Lentinula edodes 3565 and Ganoderma lucidum 9621 were compared for their ability to produce lignocellulolytic enzymes in submerged (SM) and surface liquid (SL) fermentation of hydrolysed colza straw lignin waste that remained after the production of furfural and bioethanol (CS lignin). Application of cultivated mushrooms to dispose of pretreated colza straw agricultural waste is an approach to decrease the quantity of residual lignin while simultaneously obtaining active substances, e.g., the ligninolytic enzyme complex from mycelium. The effect of adding CS lignin to culture media on the yield of L. edodes and G. lucidum mycelium and extracellular laccase activity was studied. It was revealed that the mycelial growth of G. lucidum on solid media was significantly improved by adding CS lignin. Laccase activity during SL cultivation of L. edodes on medium with CS lignin gradually increased over the experiment starting on day 21 and peaked at 520 U/mL on day 28. G. lucidum expressed the maximum laccase activity, 540 U/mL, during the first 14 days of mycelium SM cultivation. Extracellular laccase activity was enhanced about 35- to 40-fold at cultivation of L. edodes and about 10- to 15-fold in the case of G. lucidum by supplementing liquid culture media with CS lignin.

Ganoderma lucidum promotes sleep through a gut microbiota-dependent and serotonin-involved pathway in mice

Ganoderma lucidum is a medicinal mushroom used in traditional Chinese medicine with putative tranquilizing effects. However, the component of G. lucidum that promotes sleep has not been clearly identified. Here, the effect and mechanism of the acidic part of the alcohol extract of G. lucidum mycelia (GLAA) on sleep were studied in mice. Administration of 25, 50 and 100 mg/kg GLAA for 28 days promoted sleep in pentobarbital-treated mice by shortening sleep latency and prolonging sleeping time. GLAA administration increased the levels of the sleep-promoting neurotransmitter 5-hydroxytryptamine and the Tph2, Iptr3 and Gng13 transcripts in the sleep-regulating serotonergic synapse pathway in the hypothalamus during this process. Moreover, GLAA administration reduced lipopolysaccharide and raised peptidoglycan levels in serum. GLAA-enriched gut bacteria and metabolites, including Bifidobacterium, Bifidobacterium animalis, indole-3-carboxylic acid and acetylphosphate were negatively correlated with sleep latency and positively correlated with sleeping time and the hypothalamus 5-hydroxytryptamine concentration. Both the GLAA sleep promotion effect and the altered faecal metabolites correlated with sleep behaviours disappeared after gut microbiota depletion with antibiotics. Our results showed that GLAA promotes sleep through a gut microbiota-dependent and serotonin-associated pathway in mice.

Ganoderma lucidum stimulates autophagy-dependent longevity pathways in Caenorhabditis elegans and human cells.

The medicinal fungus Ganoderma lucidum is used as a dietary supplement and health tonic, but whether it affects longevity remains unclear. We show here that a water extract of G. lucidum mycelium extends lifespan of the nematode Caenorhabditis elegans. The G. lucidum extract reduces the level of fibrillarin (FIB-1), a nucleolar protein that correlates inversely with longevity in various organisms. Furthermore, G. lucidum treatment increases expression of the autophagosomal protein marker LGG-1, and lifespan extension is abrogated in mutant C. elegans strains that lack atg-18, daf-16, or sir-2.1, indicating that autophagy and stress resistance pathways are required to extend lifespan. In cultured human cells, G. lucidum increases concentrations of the LGG-1 ortholog LC3 and reduces levels of phosphorylated mTOR, a known inhibitor of autophagy. Notably, low molecular weight compounds (<10 kDa) isolated from the G. lucidum water extract prolong lifespan of C. elegans and the same compounds induce autophagy in human cells. These results suggest that G. lucidum can increase longevity by inducing autophagy and stress resistance.

Potent protective effects of polysaccharide peptide on vascular endothelium and cardiac remodelling in post myocardial infarction patients: A prospective double-blind randomized controlled trial

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Indonesia"s Ministry of Research and Technology/National Research and Innovation Agency grants Background Inflammation and oxidative stress contribute to endothelial dysfunction leading to progression of atherosclerosis and myocardial infarction (MI). Purpose To evaluate the effect of polysaccharide peptide of Ganoderma lucidum mycelium extracts (β-1,3/1,6-D-Glucan) as protective vascular endothelium and cardiac reverse remodelling in post MI. Methods This is a prospective, randomized double-blind clinical trial in 45 post MI patients. Treated group (TG) was given 3 divided dose of 540 mg β-1,3/1,6-D-Glucan daily for 90 days, and control group (CG) received placebo. Variable measured were EPC,CEC,IL-1,IL-6,TNF-α,hsCRP,NO,SOD,MDA and echocardiography parameters. Results β-1,3/1,6-D-Glucan administration significantly increased EPCs (P = 0.000), but not significantly reduced CECs (P = 0.069). Significant suppression was found in IL-1, IL-6 and TNF-α (all P &amp;lt; 0.05), but not in hsCRP (P = 0.064). TG exhibited significant elevation of NO (P = 0.02) and SOD (P = 0.023), and reduction of MDA (P = 0.001). TG revealed significant improvement of LVEF, LVMI, LVIDd, RWT, RWMA and LV diastolic dysfunction (all P &amp;lt; 0.05); but not in FS and TAPSE (P = 0.24, P = 0.20; respectively). Conclusions Polysaccharide peptide exhibits potent protective vascular endothelium and cardiac reverse remodelling in post MI patients, hence promising as add-on medication on top of standard medical regiment.
