Two protein-polysaccharide fractions, GLA and GLB, respectively, were prepared from the pileus of the fully grown carpophores and the tips of the growing carpophores of Ganod erma lucidum. At a dose of 100mg/kg/day ip, GLA and GLB inhibited the growth of sarcoma 180 solid tumor in ICR mice by 56.3% and 81.8%, respectively. In a flow cytometric (FCM) analysis, GLA and GLB enhanced the formation of lymphoblasts of BALB/c, splenic leukocytes at a concentration of 100 ${\mu}$g/ml, by 38.3% and 61, 3%, respectively. When ip injected into ICR mice, GLB exerted anti-leukopenic effect against cyclophospamide (75mg/kg, ip) in that the leukocyte counts of the peripheral blood of the normal and the cyclophosphamide-treated mice. respectively. was (11.1 ${\pm}$ 3.8) ${\times}$ 10$^3$ and (4.0 ${\pm}$ 1.8) ${\times}$ 10$^3$, while the GLB-cyclophosphamide treated mice showed a leukocyte count of (10.8 ${\pm}$ 5.1) ${\times}$ 10$^3$ CELLS/${\mu}$l. These results suggest that GLB is a promising candidate for an effective, cancer immunotherapeutic agent.

Antimicrobial activity of GL (the aqueous extract from the carpophores of Ganoderma lucidum ($F_RK_{KARST}$) was tested in vitro aginst Gram positive and Gram negative bacteria by serial broth dilution method, and the antimicrobial activity was expressed by minimal inhibitory concentration (MIC). Among fifteeen species of bacteria tested, the natimicrobial activity of GL was of antimicrobial combinations of GL with four kinds of antibiotics (ampicilin, cefazolin, oxytet-racycline and chloramphenicol), the fractional inhibitory concentraction index (FICI) was determined by checkerboard assy for each stain. The antimicrobial combinations of GL with four antibiotics resulted in additive effect in most instances, synergism in two instances, and antagonism in two instances. Synergism was obversed when GL was combined with cefazolin against Bacillus subtilis and Klebsiella oxytoca.

To determine contents of inorganic elements of Ganoderma lucidum, the horn-shaped carpophores and the pileus of Ganoderma lucidum were incinerated and analyzed by inductively coupled plasma atomic emission spectrophotometry. The ash contents of the pileus and the horn-shaped carpophore were 1.48% and 1.40%, respectively. The pileus contained calcium, magnesium, sodium, manganese, iron, zinc and germanium in that order. The horn-shaped carpophore contained magnesium, calcium, zinc, manganese, iron, copper and germanium in that order. To examine the protein-bound polysaccharide from Ganoderma lucidum for immunopotentiating activity, its fruit bodies were extracted with hot water. Purification of the extract was carried out by acetone precipitation and dialysis. The fraction obtained during the purification procedure consisted of a polysaccharide moiety (51%) and a protein moiety (5%). When the compound was administered intraperitoneally to the mice at a dose of 50mg/kg, it enhanced the accumulation of the peritoneal exudate cells, macrophage and polymorphonuclear leucocytes, thereby indicating immunopotentiation.

To examine components of Ganoderma lucidum for anti-human immunodeficiency virus (HIV) activity, the aqueous extracts of its basidiocarps were separated into high-molecular-weight (HMF) and low-molecular-weight (LMF) fractions. These fractions were used in XTT [2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino) carbonyl]-2H-tetrazolium hydroxide] antiviral assay which can quantitatively measure cytopathic effects of HIV-1 on CEM, human T lymphoblastoid cell line. The CEM cell line added with serial diluted HMF or LMF was cultured in the absence or presence of HIV-1. The results showed that the LMF of the aqueous extract strongly inhibited cytopathic effect of the target cell induced by HIV-1. When two-fold serially diluted LMF ranging from $40.97{\mu}g/ml$4 to 125.00 .mu.g/ml was added to the virus-free culture system, no toxicity on the target cells was detected in all the concentrations tested. However, when it was added to the HIV-infected culture system, the viabilities of the target cell reached a plateau recovering its viabilities to 71.7% and 82.5% in experiment-1 and -2 at 15.60 .mu.g/ml, respectively. The cell viabilities were then gradually decreased but maintained at more than 50% above 31.20 .mu.g/ml concentration. On the contrary, HMF did not prevent any HIV-induced cytopathic effect at any concentrations tested on this cell line. From these results, negligible toxicities were observed by both HMF and LMF of G. luciolum, and recovery of cell viability in HIV infected target cell was induced only by LMF of the carpophores.

To investigate antitumor components of Korean higher fungi, the carpophores of Ganoderma lucidum (Fr.)Karst. were collected at Gal-mae-ri in Gyeong-gi Province and extracted with 0.1N sodium hydroxide solution. The extract was purified by dialyzing through Visking tube and a dark brownish power was obtained. The antitumor activity of the fraction was tested against sarcoma 180 implanted in mice. The tumor inhibition ratio of the fraction against the tumor was 87.6% in doses of 50 mg/kg/day for the period of ten days. The tumor in five of 15 mice was completely regressed. The antitumor fraction was chemically analyzed and found to be a complex of polysaccharide and protein, from which four monosaccharides and eighteen amino acids were identified.
