Present review is built on base of research work on Ganoderma lucidum in our laboratory. A great deal of experimental evidence has suggested that the pharmacological activities of Ganoderma lucidum (Lingzhi) are related to anti-oxidative and free radical scavenging activity. The anti-oxidative and free radical scavenging effects of polysaccharides and triterpenoids isolated from Ganoderma lucidum in different oxidative injury models including tert-butylhydroperoxide (tBOOH)- damaged mice peritoneal macrophages, alloxan-induced diabetes, experimental liver injury models induced by carbon tetrachloride (CCl4), D-galactosamine (DGal) and Bacillus Calmette-Guerin (BCG) plus lipopolysaccharides (LPS) were investigated. It is also demonstrated that Lugu lingzhi, one of Ganoderma product, significantly inhibited LDL oxidation mediated by endothelial cells and decreased monocyte adhesion to endothelial cell (EC) induced by Oxidative low-density lipoprotein (ox-LDL) and advanced glycation endproducts (AGE). Lugulingzhi-treated serum could markedly inhibit the expression of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-l) induced by ox-LDL and AGE.

Mycelia of Pleurotus ostreatus, Phellinus linteus, Ganoderma lucidum and Lentinus edodes were cultured in the selected cereals to generate functionally active cereals. The optimum water contents for the mycelial growth were 50%(wt/wt) for brown rice, barley and soybean and 75% for wheat and corn, respectively. P. ostreatus grew well in the most cereals while the mycelial growth of P. linteus, G. lucidum and L. edodes in soybean were siginificantly retarded. The contents of β-glucan and glucosamine in the mycelial cereals were determined. Wheat cultured with mushroom mycelia showed high ß-glucan content. Especially, wheat with G. lucidum contained the highest value of 26.16%. Soybean cultured with G. lucidum showed two-fold increase in glucosamine content with 9.63% of total mass while wheat showed 7.91%. Overall, wheat cultured with G. lucidum was the best functional cereal in terms of β-glucan and glucosamine contents.

Objectives We studied on anti-allergic effects of Ganoderma lucidum herbal acupuncture(GHA) and Ganoderma lucidum extract(GE). Methods In vivo, Animals were herbal-acupunctured GHA at both B13s three times for 5 days. Then, we investigated compound 48/80-induced active systemic anaphylatic shock using ICR mice and anti-DNP IgE-induced passive cutaneous anaphylaxis using Sprague Dawley rat. In vitro, we measured cell viability, b-hexosaminidase release, IL-4 and TNF-a from RBL-2H3 cells, and nitric oxide from Raw264.7 cell after treatment of GE of various concentrations. Results In vivo, GHA pretreatments at both B13s inhibited compound 48/80-induced active systemic anaphylatic shock. Passive cutaneous anaphylaxis were inhibited by GHA10 and OP. In vitro, $0.1\;{\sim}\;2%$ GE treatments were not affect on cell viability and inhibited b-hexosaminidase release, IL-4, TNF-a and nitric oxide. Conclusions These results suggest that GHA and GE may be beneficial in the inhibition of allergic inflammatory response.

Ganoderma lucidum produced the potent pectolytic enzymes for clarifying cloudy fruit juice. Among the purified polygalacturonases (endo- and exo-polygalacturonase), endo-polygalacturonase had a good effect on juice clarification. The optimum temperature and concentration of endo-polygalacturonase for the juice clarification were $40^{\circ}C$ and 4 unit/5 ml juice, respectively. The apple juice was almost completely clarified at $40^{\circ}C$ for 60 min. It was suggested that culture filtrate of Ganoderma lucidum or it's ammonium sulfate fraction should be used as a good source of pectolytic enzyme for juice clarification.

Ganoderma lucidum has a long history of use as a traditional medicine in Asian countries. However, the taxonomy of Ganoderma species remains controversial, since they were initially classified on the basis of their morphological characteristics. Recently, it was proposed that G. lucidum from China be renamed as G. sichuanense or G. lingzhi. In the present study, phylogenetic analysis using the internal transcribed spacer region rDNA sequences of the Ganoderma species indicated that all strains of the Korean 'G. lucidum' clustered into one group together with G. sichuanense and G. lingzhi from China. However, strains from Europe and North American, which were regarded as true G. lucidum, were positioned in a clearly different group. In addition, the average size of the basidiospores from the Korean cultivated Yeongji strains was similar to that of G. lingzhi. Based on these results, we propose that the Korean cultivated Yeongji strains of 'G. lucidum' should be renamed as G. lingzhi.

To examine influence of artificial digestive juice on the antitumor activity of Ganoderma lucidum-A(GL-A), protein-bound polysaccharide from Ganoderma lucidum, we compared the digested protein-bound polysaccharide with undigested one both on immunopotentiating activity and influence of digestive juices. Protein-bound polysaccharide GL-B was obtained by digesting the antitumor component GL-A with artificial digestive Juices in vitro. When GL-A was administered orally to sarcoma 180 tumor-bearing ICR mice, the life prolonging effect was exhibited in a dose dependent manner Not only GL-A but GL-B increased the production of colony forming unit (CFU) to 10- and 8-fold of that of the control, respectively. Both of the protein-bound polysaccharides also showed the secretion of nitric oxide in RAW 264.7 cell lines to 3.5-and 3.7-fold of that of the control, respectively: GL-A activated components of the alternative complement pathway, whereas GL-B did not. In humoral immunity GL-A increased the activity of alkaline phosphatase in differentiated B cells to 3 times and GL-B to 4 times of that of the control. These results showed that the artificial digestive juices had no influence on the antitumor activity of the protein-bound polysaccharide from Ganoderma lucidum and that its immunomodulating activity retained after treatment with artificial digestive juice. And this provides a basis of the protein-bound polysaccharide of Ganoderma lucidum as an peroral anticancer drug.

This study has been investigated the effect of Ganordema lucidum extract on Saccharomyces cerevisiae growth and physiology. Sacch. cerevisiae was inoculated in Hayduck solution medium which were added 0, 0.1, 0.5, 1.0% extracts of G. lucidum and fermented at $30^{\circ}C$ for 5 days respectively. Some results about cell number, alcohol content and carbon dioxide products during fermentation are as follows: $CO_2$ evolution of yeasts by addition of extract of G. lucidum was more increased than control after the fermentation for 120 hours. It was the most abundant by addition of 1.0% extract of pot-culture G. lucidum. The cell number of yeasts during the fermentation w as more increased than control by addition of extract of G. lucidum. It was by addition of extract of pot-culture G. lucidum that the cell number of yeasts was more increased than by each addition of extract of wood-culture G. lucidum and G. lucidum. Dry weight of yeasts was systematically increased in addition of extract of pot 0.5%>pot 1.0%>wild 1.0%>wood 1.0%=wood 0.5%>wild 0.5%>wild 0.1%>pot 0.1%>wood 0.1%>control in order. It was by addition of extract of pot-culture G. lucidum that. the dry weight of yeasts was more increased than by addition of woodculture G. lucidum and wild G. lucidum. Alcohol quantity by addition of extract of G. lucidum was increased more than 3 times after the fermentation for 72 hours compared with control but there was no any difference among them after the fermentation for 120 hours. The rate of sugar-consumption and fermentation of yeast by addition of extract of G. lucidum was highly increased during the early fermentation. As times went, there was no difference among them during the subsequent fermentation.

The aim of this study is to investigate the effect of Hovenia dulcis (oriental raisin tree) extract on ganodermanondiol (GN) contents in Ganoderma lucidum (G. lucidum) mycelia. GN has a triterpenoid structure and is one of the major active components of G. lucidum. Furthermore, we previously proved its inhibitory effects on tyrosinase activity and melanin biosynthesis in B16F10 melanoma cells. In this study, we observed significantly increased GN contents in G. lucidum mycelial extracts supplemented with 15% (v/v) oriental raisin tree extract (ORTE) by HPLC analysis. In addition, melanogenesis was significantly inhibited by G. lucidum extract supplemented with 15% ORTE when compared to G. lucidum extract without ORTE supplementation. Furthermore, mycelial growth of G. lucidum was increased by ORTE supplementation in both solid and liquid cultivation. These results suggest that the oriental raisin tree is useful as natural ingredient for increasing GN biosynthesis as well as whitening effect of G. lucidum.
