Agaricus blazei Murill, a mushroom which is well known as a potent antitumor agent, contains abundant pharmaceutical substances. To identifY the major components of Agaricus blazei Murill fruiting bodies cultivated in a Korean local farm was analyzed. There were not large differences in chemical compositions of inorganic substances, carbohydrates, amino acids and fatty acids between Agaricus blazei Murill fruiting bodies cultivated in Korea and those in Japan. However, carbohydrate composition was significantly lower in Agaricus blazei Murill of Korea compared to those of Japan. Total amino acid contents were 280.75 mg% in Agaricus blazei Murill fruiting bodies. Sixteen species of amino acid were identified by high performance liquid chromatography except cysteine. Linoleic acid, the most abundant fatty acid contained in Agaricus blazei Murill fruiting bodies, was estimated to be 78.3% of total fatty acids.

Polysaccharide-based dressings have increasingly become viable alternatives to somewhat less biocompatible and often problematic cotton or viscose gauzes traditionally used for wound dressings. Polysaccharide which is particularly abundunt in Agaricus blazei Murill is known as the bioactive materials. Polysaccharide extracted from Agaricus blazei Murill enhances the recovery of the damaged epidermal tissue and the production of epithelial cell growth factors which are necessary to heal the burn and wound on the epidermal tissue. In this study, the biopolymer delivery system of polysaccharide extracted from Agaricus blazei Murill into epidermal tissue was elucidated using the skin permeating enhancer in vitro. The enhancing effects of various penetration enhancers and some other enhancers on the permeation of ${\beta}-glucan$ were evaluated using Franz diffusion cell. Permeation of polysaccharide in nomal and burn skin was compared. Polysaccharide was studied for the burn and wound healing activity in the epidermal tissue on rats.

The effect of methanol extract from Agaricus blazei Murill on the hepatotoxicity was investigated $CCl_4$ is one of the oldest and most widely used toxins for the induction of hepatic damages and fibrosis in experimental animals. In this study, male Sprague-Dawley(SD) rats were randomly divided into 6 groups of the control(C), $CCl_4(T),\;CCl_4$ and high fat group(TL) with matching sub-groups of Agaricus blazei Murill extract-fed groups of CA, TA and TLA. Methanol extracts of Agaricus blazei Murill were fed 50 mg/kg B.W daily via drinking water. A 1.2 mL of $CCl_4/kg$ body weight was administered by oral intubation twice a week for total of six times. The levels of total-cholesterol, TG, LDL and LDL-phospholipids were elevated by $CCl_4$ treatment as compared to the control(C). However, Agaricus blazei Murill methanol extract feeding in the group of TA and TLA significantly(p<0.05) decreased TG by 53.1 % and 17.9% compared to the internal control of T and TL, respectively. Triglyceride of TL was increased by 3.33 times(p<0.05) compared to the control(C) with $CCl_4$ and high fat administration from 3.78 mg/g to 12.60 mg/g liver. The extract(CA) also reduced kidney weight compared to the control(C). With the administration of high fat and $CCl_4$(TLA), the extract reduced the organ weight of both liver and kidney and further, significantly reduced TG, total cholesterol and GTP activity. Hepatoprotective effects of Agaricus blazei Murill on GOT, GPT, AP and LDH activities were enhanced by the extract feeding. Electronmicrograph showed that $CCl_4$ deteriorated the structure of cytoplasmic matrix with its uneven distribution. However, the extract reconstituted the damaged cytoplasm and stimulated mitochondriogenesis. The above results suggest that Agaricus blazei Murill may have a possible protective effect against chemically induced liver damage and further help to reduce the symptoms of fatty liver.

The purpose of this study was to determine the optimal mixing ratio of Agaricus blazei Murill powder and butter in the preparation of cookies. The experimental design utilized herein was based on central composite design for response surface methodology, which included 10 experimental points, including 2 replicates for Agaricus blazei Murill and butter. The physical, mechanical, and sensory properties of the test were measured, and these values were applied to the mathematical models. A canonical form and perturbation plot showed the influence of each ingredient on the final mixed product. The spread ratio increased significantly with an increase in Agaricus blazei Murill powder and butter (p<0.05). The response surface methodology was applied to evaluate the effect of Agaricus blazei Murill powder and butter on cookie moisture and color (L, a) (p<0.001). Sensory evaluation showed significant values for color (p<0.05), flavor (p<0.05), texture (p<0.05) and overall quality (p<0.01) in the predicted model. The optimum formulation by numerical and graphical methods was calculated as follows: Agaricus blazei Murill powder 3.63 g, butter 55.37 g.

The Basidomycetes fungus Agaricus blazei Murill has been well known as a health food for the prevention of cancer, diabetes, hyperlipidemia, arteriosclerosis and chronic hepatitis. This study was concentrated to investigate the characteristics of crude protein-bound polysaccharides(PBP) compositions extracted from Agaricus blazei Murill. In order to produce crude polysaccharides, culture conditions were examined using YMK media. Total sugars and protein contents of PBP were detected by phenol-sulfuric acid method and Bradford -assay. Hexosamine was found to be involved in the linkage, N-linked and O-linked types. To identify helical conformation existence, wavelength was measured using Congo red after the treatment with alkali solution.

A fraction (CMEx-AH-${\beta}$) of water-soluble polysaccharides, showing selective antitumor activities, was isolated from the mycelia of solid cultured Agaricus blazei Murill by hot-water extraction, ethanol precipitation, and series of chromatography. Chemical characteristics of CMEx-AH-${\beta}$, were as follows: carbohydrate content, 48%; monosaccharide composition, Man:Glu:Gal (2:93:5); molecular weight, $2{\times}10^5$; uronic acid content, 6.2%. Fundamental structure of CMEx-AH-${\beta}$, was deduced as ${\beta}-(1\;{\rightarrow}\;6)$-D-glucan with ${\beta}-(1\;{\rightarrow}\;3)$-D-glucosidic side chains based on results of methylation and $^{13}C$ NMR spectroscopic analyses.

Basidiomycete, Agaricus blazei murill has grown Brazil naturally. It was first cultivated 1997 in Korea. Proteoglycan or polysaccharide which have the effect of immunopotency and anticancer were extracted from it. From the mycelium of cultivated mushroom, were extracted lectin, linoleic acid, FIII-2-b, and simmilar to glucomannan from fruit body of Basidiomycete Agaricus blazei. Fruit body was more studied than mycelium. The experiments were most in vivo study. The effect were shown on S-180, MethA tumor, Ehrlich ascites carcinoma, Shionogi carcinoma 42, Meth A fibrosarcoma by transferation of tumor cell line, specially effectiveness on the S-180. About immunopotenciation, were shown as activation of NK cell, pancreatic T-cell, helper T cell, enhancement of population of cytotoxity T cell. It was effect on the MethA tumor cells in vitro cell cytotoxity and has induction of apoptosis. Forthermore cytotoxity of many other tumor cell line, aneiognensis, cell cyle studies will be needed.

The polysaccharides were extracted from fruiting body, mycelia, and cell-free broth of Agaricus blazei Murill. The crude polysaccharides were obtained by the ethanol addtion. They were further purified using ion-exchange chromatography and gel chromatography. Ion-exchange chromatography using DEAE-cellulose column separated neutral and acidic polysaccharides. Neutral polysaccharides were then purified with gel filtration chromatography. For single peak obtained from gel filtration chromatography was molecular weight was measured with Sepharose CL-6B. The same procedure with acidic polysaccharides were performed to get the purified polysaccharides.
