LA recherche coopérative sur GANODERMA LUCIDUM
(Zhi Ling / Reishi)

Le problème affinée par les travaux de recherche coopérative de l'Université médicale de Shanghai, Shanghai, en Chine et Wakan Shoyaku botanique Institute, Tokyo, Japon est que Ling Zhi(Reishi) a pour effet d'améliorer la microcirculation et l'amélioration de l'hémodynamique. Toutefois, il disait «Restos Reishi pendant une longue période pourrait faire l'aise personne et de prolonger la vie sans la sénilité »dans« Sheng Nong Ben Cao Jing »et« Ben Cao Gang Mu ".

* Confort signifie aucun symptôme.
prolonger la vie * sans la sénilité, c'est avoir une vie très longtemps.
Certes, il serait impossible s'il n'y avait pas une telle base de l'amélioration
microcirculation. Les données recueillies dans ce livre semble dans l'attente. Il a prouvé que Reishi (LZ) a augmenté hémodynamique de la microcirculation sanguine en diminuant la viscosité. Il ya non seulement les données de la recherche médicale, mais aussi celle des cliniques enquête. En outre, grâce aux efforts des enseignants de médecine de Shanghai Université, il a également prouvé que Reishi (LZ) a pour effet de compensation et les radicaux effet de deux voies de modulation immunitaire. J'ai payé cordialement attention durant les 17 dernières ans.

Le formulaire de résultat fructueux de la "recherche coopérative" me rend très heureux. Reishi,comme aliment, n'est pas un fait de la botanique aucun certificat scientifique Japon. Toutefois, comme une sorte de drogue quelques Reishi peut être utilisé comme botanique selon le
l'expérience acquise dans la médecine orientale, sans aucun effet secondaire.
"La recherche sur le Ganoderma lucidum, Part One» n'est pas seulement un symbole qui
elle avait fait un grand effort, mais aussi une base de plus de compréhension de la traditionnelle et
l'usage moderne de Reishi (LZ) dans la recherche continue à l'avenir.
La grande signification et le contenu riche de la médecine expérimentale et de la pharmacie
ont été énumérés par le présent livre. Les efforts et l'instruction des chercheurs à Shanghai
Université médicale serait vivement appréciée.
Je tiens à remercier le professeur et président Zhaoyou TANG, professeur et vice-
Président Shineng ZHU, Université médicale de Shanghai à nouveau pour leur amélioration et
le renforcement des activités de recherche. Je dis aussi Merci encore à M. Masaru
KOBAYASHI, président, Wakan Shoyaku botanique Institut pour sa gentillesse d'offrir
le grand soutien financier pour des travaux de recherche.

GANODERMA LUCIDUM (LING ZHI REISHI ) CAN PROLONG LIFE SAY RESEARCHERS IN CHINA AND JAPAN...PART 1

THE COOPERATIVE RESEARCH ON GANODERMA LUCIDUM
(Ling Zhi / Reishi )
The problem clarified by the cooperative research work of Shanghai Medical University,
Shanghai, China and Wakan Shoyaku Botany Institute, Tokyo, Japan is that Ling Zhi
(Reishi) has the effect of improving microcirculation and enhancing hemodynamics.
However, it was saying “Eating Reishi for a long period might make person comfortable
and prolong the life without senility” in “Sheng Nong Ben Cao Jing” and “Ben Cao Gang
Mu”.

* Comfort means no symptom.
* Prolonging life without senility means having a long long life.
Certainly, it would be impossible if there were no such basis of improving
microcirculation. The data collected in this book seems in expectation. It has proved that
Reishi (LZ) increased hemodynamics in microcirculation by decreasing the blood
viscosity. There are not only the data in medical research but also that of clinical
investigation. In addition, with the efforts of the teachers of Shanghai Medical
University, it has also proved that Reishi (LZ) has the effect of clearing radicals and the
effect of two-way immune modulation. I have paid cordially attention for the past 17
years. The fruitful result form the “Cooperative Research” makes me very excited.
Reishi could only be a food not a botany because of no scientific certificate in
Japan. However, as a few kind of drug Reishi might be used as a botany according to the
past experience in Eastern Medicine without any side effect.
“The Research on Ganoderma Lucidum, Part One” is not only a symbol to which
it had made a great effort, but also a basis of more understanding the traditional and
modern usage of Reishi (LZ) in the continuing research in future.
The great significance and rich contents of experimental medicine and pharmacy
were listed by this book. The efforts and instruction of the researchers in Shanghai
Medical University would be appreciated very much.
I would like to thank Professor and President Zhaoyou TANG, Professor and Vice
President Shineng ZHU, Shanghai Medical University again for their enhancing and
strengthening of the search work. I also say many thanks again to Mr. Masaru
KOBAYASHI, President, Wakan Shoyaku Botany Institute for his kindness of providing
the big financial support for research work.

REGARDING TO THE MATERIAL LING ZHI ( REISHI ) USED IN
EXPERIMENTS
“The Cooperative Scientific Research on Botany Ling Zhi (Reishi)” accomplished
by Shanghai Medical University, Shanghai, China and Wakan Shoyaku Botany Institute,
Tokyo, Japan started in 1989. The total material Ling Zhi (Reishi) including seeds,
powder and its extract was produced in the special Reishi cultivated farm and was
provided by Wakan Shoyaku Botany Institute. It should be declared that the material
Reishi used in the experiments were taken randomly from the original material produced
in the Institute without and special ways.
The brief introduction of Reishi cultivated farm:
Tumagoi-Mura Farm, Wakan Shoyaku Botany Institute
The first farm 9 900m² The second farm 13 000m² Total 22 900m²
(Located in Imai-Sennoiri, Tumagoi-Mura, Agatuma-Gun, Gunma, Tapan)
Wakan Shoyaku Botany Institute is the biggest Reishi (LZ) produced and
researched organization in Japan. It includes 60 cultivated warm rooms, original wood
cultivated building, seeds dried building. Besides, there are general cultivated building
and office building with water cleared apparatus, big sterilized equipment and other
instruments.
The cultivated farm is located at the altitude of 1 030 meters above sea level. It is
a natural environment with little changed whether, good quality of water, fresh air and
getting the original wood at that place. It is benefit to the cultivation and treatment of
Reishi (LZ). The condition of original Reishi (LZ) produced with stable quality is
ensured in the farm. In addition, with the cultivated technique researched and created in
many years Wakan Shoyaku Botany Institute had the patent of management and
cultivation of sustaining the activity of original bacterial strain. All these might
guarantee the stable quality.

Effects of Ling Zhi on Lymphocyte Proliferation
— Immunopharmacological Study (1)
XU Weimin ZHANG Luoxiu MIAO Honghua
Abstract The study was to evaluate the process of lymphocyte
proliferation induced by the hot water extract of Ling Zhi (LZ, Ganoderma
Lucidum
, Fr. Karst) cultivated in Tokyo, Japan. It was examined by assessing
the effect of LZ on ³H-TdR uptaken by cultured spleen cells alone or in the
presence of Con-A or Lps. LZ 300 mg/kg po. qd. x 10 in vivo or 10 ~ 500
μg/ml alone in vitro stimulated lymphocytes proliferation directly, but 1 000
μg/ml of LZ inhibited. The activity of frozen thawed part was stronger than
that of soluble part. The effect of LZ on lymphocyte proliferation induced by
Con A resulted in diverse regulatory activity. It was mainly related to both
concentrations of Con A and LZ. In general, LZ stimulated lymphocyte
proliferation in the presence of suboptimal concentration of Con A (0.625
μg/ml) and depressed when the cells were highly activated by optimal
concentration of Con A (2.5 μg/ml) in a concentration dependent fashion.
LZ antagonized the activity of cyclophosphamide and promoted the
lymphocyte proliferation in the immunosuppressed mice induced by
cyclophosphamide. However, LZ had no stimulative activity on lymphocyte
proliferation induced by Lps in vitro or in vivo. It implied that B cells may
have different mechanism from T cells to interact with LZ.
Key words Ling Zhi (LZ, Ganoderma Lucidum, Fr. Karst); Lymphocyte
proliferation

The fungus Ling Zhi (LZ, Ganoderma Lucidum, Fr. Karst) exhibits wide
pharmacological effects and has been used as a health protective drug for a long time.
However, the investigation of LZ on immune system was rare and the mechanism was
poorly understood. The aim of this study was to evaluate the effect of LZ on lymphocyte
proliferation.
Dept. of Pharmacology, School of Pharmacy, Shanghai Medical University, Shanghai, China
Materials and Methods
Animals
Kunming mice, male, 18 ~ 22 g, were supplied by the Animal Center, Shanghai
Medical University.
Reagents
The hot water extract of LZ was provided by Wakan Shoyaku Botany Institute,
Tokyo, Japan. A certain amount of LZ extract was grinded and dissolved in normal
saline containing 0.2% carboxymethyl cellulose sodium (CMC) shaken in 80ºC water
bath for 4h. This suspension was used for in vivo study. For in vitro study, a little
amount (about 10mg) of LZ extract was dissolved in normal saline and rotated slowly in 80ºC
water bath for 2h then centrifugated 1 600 rpm 10 min. The supernatant was kept at 4ºC until
study. Before experiment this solution was diluted to desire concentration. It was named as
soluble part (Part A). When LZ was dissolved and shaken in 80ºC water bath then rapidly frozen
(-30ºC) and thawed (37ºC) 3 times, it was named as frozen thawed part (Part B).
PRMI-1640 was purchased from GIBCO Co. It contained Hepes 15 mM, Penicillin 100
U/ml, Streptomycin 100 μg/ml, NCS 10%, 2-Mercaptoethanol (2-ME) 5 x 10¯5 mmol, pH 7.3.
Con A, S were purchased from Sigma Co.
³H-TdR was provided by Shanghai Institute of Nuclear Research, Chinese Academy of
Sciences and the specific activity was 1 100 GBq. Mmol.
Lymphocyte proliferation in vitro (1)
Mice were sacrificed by cervical dislocation and the spleens were removed with sterile
technique. The spleen cells were collected after passing through a nylon screen and red blood
cells in the cell suspension were hemolyzed with distilled water for 30 s, then osmoregulated.
After washing with RPMI-1640 for 3 times the cells were seeded into each well of 90-well
microplate and various concentrations of LZ and Con A or LPS were added in alone or
combination. The plates were cultured at 30ºC with 5% CO2 in a humidified atmosphere for 48 h.
For the last 6 h each well as pulsed with 9.25 kBq ³H-TdR. The cells were harvested using a
multiple automatic sample harvester onto a fibroglass filter paper which was then dried and the
radioactivity incorporated were counted by a liquid scintillation counter. All counts/min values
shown were the mean of triplicate sample ± SD. Statistical analysis was carried out by student’s
test.
Mitogenic activity of LZ in vivo(2)
Mice were randomly divided into 2 groups. The mice in control group were given 0.2%
CMC 0.5 ml po. qd. x 10 and treated group with LZ 300 mg/kg po. qd. x 10. The spleen cells
were prepared as mentioned above.
The effects of LZ on immunosuppressed mice
40 mice were divided into 4 groups randomly. The mice in control group were given 0.2%
CMC 0.5 ml po. qd. x 10. In cyclophosphamide (CYA) group, mouse were taken CYA 10 mg/kg
ip. qod. x 2, q3d x 2. The mice of LZ groups were given LZ 150, 300 mg./kg, po. Combined
with CYA 10 mg/kg, ip. qd. x 2, qod. x 2 respectively. The spleen cells were prepared as the
same technique mentioned above.
Results
Effect of LZ on lymphocytes proliferation in vitro
In vitro, LZ alone stimulated the ³H-TdR uptake at 1 ~ 500 μg/ml (Part A) and at 1 ~ 10 μg/ml
(Part B) without mitogen. And turned to inhibition at right concentration. The activity of Part B
was stronger than that of Part A. Part B inhibited lymphocyte proliferation at less concentration
(Tab. 1-1).

Discussion
Since TNF has been widely noticed, several investigators have developed in vitro
cell cytotoxicity assays for TNF. Flick et al compared four published in vitro assays
which measured cell cytotoxicity of TNF(4). These included determination of residual cell
number by crystal violet staining in the presence and absence of Actinomycin D, lack of
viability as determined by neutral red uptake and ³H-Thymine release in cytotoxin treated
L929 cells. Flick compared these methods and discovered that treatment of L929 cells with
Actinomycin D followed by crystal violet staining was the most sensitive method
measured. We set up this method of assay TNF activity. We observed various
conditions, L929 cell density, the amount of TG, the dosage cause of Actinomycin D and
the mice strain. We found that crystal violet culture was a sensitive and repeatable assay.
Addition of Actinomycin D to the cell cultures greatly enhanced killing and shortens the
necessary incubation time to 20 h. We used this method for all the experiments.
From this study it was shown that LZ enhanced the production of TNF in vitro. LZ
itself had no direct cytotoxic activity against L929 cells. There was less pronounce
synergistic activity between LZ and γTNF under this condition. However LZ increased
the TNF production both in vitro and in vivo. Even preincubation of macrophages with
LZ for 8 h promoted the production of TNF. We have reported that LZ stimulated
macrophage phagocytosis and enhanced the carbon particles clearance activity. Now we
further demonstrated that LZ elevated macrophage activity to increase the capacity of the
host defense mechanism against cancer and infection diseases through indirect
mechanism.
One must emphasize that from the in vitro study we can see LZ modulated TNF
production form 0.01 ~ 1 μg/ml LZ stimulated TNF release but higher concentration (100
μg/ml) resulted in an inhibitive activity. This further demonstrated LZ played a role as an
immunomodulator.

Introduction

Many of the currently available anti-cancer agents are derived form natural products, for instance paclitaxel (Taxol), and camptothecin (Hycamtin) amongst many others. In 2000 Professor Gordon McVie, Director-General of the Cancer Research Campaign (now Cancer Research UK) and Professor John Smith of University of Strathclyde met in Glasgow to discuss the role of medicinal mushrooms in the treatment of cancer. The CRC had become aware that these natural products were being used extensively in the Far East as nutriceuticals (dietary supplements) and as a source for the generation of pharmaceutical-grade medicines to treat a wide variety of diseases, including cancer. The substantial range of medicinal mushroom species from which different bioactive compounds can be derived suggested that the humble mushroom could be a source of novel anti-cancer agents.

This monograph is a comprehensive overview of this subject from the technology of cultivation, extraction and chemistry of medicinal mushroom bioactive compounds to the clinical evidence that suggests an important therapeutic role in cancer, and other major diseases.

Abstract. Aim: Ganoderma lucidum is a commonly used Chinese herb and an important ingredient in traditional Chinese medicine herbal formulations for immune dysfunction related illnesses. The effects of this medicinal mushroom on human colorectal cancer cells have not yet been evaluated. In this study, we investigated the effects of Ganoderma lucidum extract using SW 480 human colorectal cancer cell line. Materials and Methods: Two different fractions of Ganoderma lucidum extract, i.e., a fraction containing mainly polysaccharides (GLE-1), and a triterpenoid fraction without polysaccharides (GLE-2) were analyzed. Their antiproliferative activity was evaluated by cell proliferation assay and 3H-thymidine incorporation assay. Scavenging effects of DPPH radical were assessed using ESR-spectroscopy. Results: Our data showed that both GLE-1 and GLE-2 significantly inhibited the proliferation of SW 480 cells. The inhibitory effect of GLE-2 was much stronger than that of GLE-1. GLE-1 inhibited DNA synthesis in the cells and reduced the formation of DPPH radicals. Conclusion: Ganoderma lucidum extract inhibits proliferation of human colorectal cancer cells and possesses antioxidant properties.

Key Words: Ganoderma lucidum, colorectal cancer, SW 480, proliferation, reactive oxygen species, DPPH radicals.

The Power of the Japanese Red Reishi Mushroom

Reishi Extract and Arthritis
30 September 2009
by Dr. Markho Rafael
Reishi extract has been used in Traditional Chinese Medicine to treat arthritis and other forms of inflammation for over 2,000 years. Also commonly known
by its Latin name as “Ganoderma,” or Chinese “Ling Zhi,” Reishi is by far the most searched medicinal mushroom on the Internet with over 200,000
searches per month. And although it may not be the panacea (”cure-all”) that some hold it to be, the fact that modern research confirms it as an inflammation
modulator may help explain why it has long been heralded as such in the Orient.
In fact, Chinese medical practitioners have been prescribing Reishi extract for ages in cases of arthritis, bronchitis and other conditions involving any type of
inflammation. Modern research in Asia as well as in America and Europe confirm the validity of these uses. Out of 19 papers used for this article, 17 reported
positive results in the use or Reishi extract for arthritis. Only two were studies were inconclusive, both of which were conducted by the same research team.
(1,2)
Regarding anti-inflammatory properties in general, a study out of India (2003) demonstrated that Reishi decreased inflammation in cases of acute or chronic
edema by 56% and 60% respectively. (3) An earlier American study (1993) had already shown that, water extracts of G. pentaphyllum and G. lucidum
[Reishi] were found to possess significant anti-inflammatory activity. (4) In the references are seven additional papers listed which all conclude that Reishi
(Ganoderma lucidum) possesses potent anti-inflammatory qualities. (5,6,7,8,9,10,11)
Other research has been conducted on Reishi extract that relate specifically to arthritis. In 2006, Kenneth Blum et al. published findings in support of both the
effectiveness and safety of using Reishi extract for “joint health,” providing “clinical evidence” to back up their claim. (12)
Also that same year, a Chinese study by Xi Bao et al. came to the conclusion that Reishi plus another medicinal herbal remedy commonly used in China
seemed to have a “beneficial immunomodulatory effect” on arthritis. (13)
Just how Reishi accomplishes its beneficial influence on arthritis may have been stumbled upon by Ho et al. in 2007 (14) when they discovered that GL-PP
[Ganoderma lucidum polysaccharide peptide] helped to significantly reduce one of the causative agents of rheumatoid arthritis known as RASF, short for
“Rheumatoid Arthritis Synovial Fibroblasts.”
Several additional papers have been published that summarize positive results in the use of Reishi against arthritis. (15,16,17) One even states that Reishi
compares favorably to prednisone, albeit without side effects. (18) On the other hand, a separate study found that supplementing with Reishi helped balance
the side effects of prednisolone* that were experienced by some patients, including protein in the urine and cell toxicity. (19) (Prednisolone is the active
compound of prednisone, which gets broken down by the liver and converted to prednisolone.)
In conclusion, the body of research does seem to support the use of Reishi extract in cases of arthritis. Remember that it is important to always work
with a licensed medical practitioner when using any herb for medicinal purposes.
Note on name confusion: The name “Reishi” is Japanese for the perennial tree mushroom that American naturalists refer to as “Varnished Conk.” In China, it
is known as “Ling Zhi.” All these names usually refer to the species Ganoderma lucidum, which for the sake of distinction from other types of Reishi may
sometimes be called “Common Reishi” or “Red Reishi.”
Other related species that are often called “Reishi” include: “Hemlock Reishi” (Ganoderma tsugae),” which is common on hemlock trees in eastern U.S.; the
Chinese species known as “Black Reishi” (Ganoderma sinense); another American species found on the west coast which is sometimes referred to as “Red
Reishi” (Ganoderma resinaceum), although “Red Reishi” more often refers to G. lucidum in contrast to “Black Reishi,” G. sinense; and finally two Japanese
species, one that is sometimes known as “Purple Reishi” Ganoderma japonicum, and one without any English name, Ganoderma neo-japonicum.
