This study was carried out to investigate the dose dependent antifibrotic effects of polysaccharide from mycelium of Ganoderma lucidum. The experimental hepatic cirrhosis was induced by bile duct ligation/scission (BDL/S) in rats. BDL/S rats in each group were dosed 0.5 mg, 2.0 mg, 5.0 mg or 10.O mg/rat/day orally for 4 weeks after the operation. Antifibrotic effects were evaluated by serum biochemical values, hydroxyproline contents, and light microscopical histology. The results obtained were as follows: 1) Hydroxyproline contents in liver of 5.0 and 10.0mg polysaccharide-treated BDL/S rats were significantly reduced 2) In serum test, ALT, AST, ALP values in polysaccharide from Ganoderma lucidum-treated group were lower than BDL/S control group 3) The hepatic damage such as hepatocellular necrosis, inflammation, bile duct proliferation and fibrosis was less severe in the livers of 2.0 mg and 5.0 mg polysaccharide-treated rats. These results suggest that polysaccharide from mycelium of Ganoderma lucidum to be a promising agent for the inhibition of hepatic cirrhosis.

Nine species of genus Ganoderma collected in Korea and abroad including Ganoderma lucidum complex and G. lucidum were compared by investigating growth characteristics. In the bottle culture, the mycelial growth periods of G. lucidum from Taiwan and North America was 26 to 30 days compared to that of Korean G. lucidum, which was 30 to 32 days. Cultivation period of Taiwan and North American isolates was 30 to 32 days which were 11 to 17 days shorter than those of Korean isolates. Biological efficiency of Taiwan and North American isolates were ranged from 3.3 to 5.5%, which were apparently lower than that of Korean isolates which ranged from 6.2 to 9.4%. Korean isolates had longer stipes($15{\sim}40$ mm) and more number of pileus($4{\sim}6$/bottle) than those of Taiwan and North American isolates. The G. lucidum isolates collected from Korea will be regarded as the independent species from the G. lucidum collected from Taiwan and North America since, the G. lucidum from Korea showed much different growth characteristics in various aspects compared to the G. lucidum from Taiwan and North America.

A fungal disease of the cultivated mushroom, Ganoderma lucidum, caused by Xylogone sphaerospora was epidemic throughout all cultivation areas in Korea which caused a lot of yield losses in the mushroom production. For controlling the disease, the screening of effective fungicides against the pathogenic fungus were conducted. Thirty seven commercially available fungicides were tested for their inhibitory activities on potato dextrose agar media supplemented with these fungicides at various concentrations. Twenty one fungicides significantly inhibited mycelial growth of the pathogen, Xylogone sphaerospora, but 16 fungicides had no inhibitory effect. Among these 21 fungicides, 17 fungicides also inhibited mycelial growth of Ganoderma lucidum as well, but imazalil, procymidone, triforine, and vinclozolin had no inhibitory effects. However, vinclozolin showed no inhibitory effect on mycelial growth of the mushroom even at the concentration of 50 $\mu\textrm{g}$/ml vinclozolin solution for 2 hours, and then the pathogen was inoculated. After two month-cultivation of the mushroom, over 90% of logs treated with vinclozolin without pathogen inoculation produced fruiting bodies. However, fruiting bodies were not produced form the logs inoculated with the pathogen, but not treated with vinclozolin. Fifty seven percent of logs. which were pre-treated with vinclozolin and then inoculated with the pathogen produced fruiting bodies. Based on the results, vinclozolin is effective for the control of yellow disease of the Ganoderma lucidum caused by Xylogone sphaerospora.

To determine the optimal media conditions for the detection of the extracellular cellulase activity in Ganoderma neo-japonicum, we varied three media conditions: dye reagent, pH, and temperature. We evaluated the use of four dyes, Congo red, phenol red, remazol brilliant blue, and trypan blue. To observe the effect of pH on the chromogenic reaction, we tested media ranging from 4.5 to 8.0. To research the effect of temperature on the clear zone and the fungus growing zone, we tested temperatures ranging from 15 to $35^{\circ}C$. On the whole, the best protocol called for Ganoderma neo-japonicum transfer onto media containing Congo red with a pH of 7.0, followed by incubation at $25^{\circ}C$ for 5 days. Our results will be useful to researchers who study extracellular enzyme activity in Ganoderma neo-japonicum.

These studies were attempted to investigate the preventive effect of Ganoderma lucidum extract administered concurrently with glutathione on the liver damage induced by carbon tetrachloride ($CCl_4$) in rats. S-GOT and S-GPT activities of all the pre-treatment groups were significantly decreased, as compared with those of the control intoxicated by $CCl_4$. The concurrent administrations of Ganoderma lucidum extract with glutathione (100+100mg/kg, 200+100mg/kg, and 400+100mg/kg, respectively) were more effective than the individual administrations. i.e., Ganaderma lucidtcm extract (100, 200 and 400mg/kg, respectively) and glutathione (100, 200 and 400mg/kg, respectively). On the determination of lipid-peroxidation in liver, the concurrent administrations of Ganoderma lucidum extract with glutathione (100+100mg/kg, and 200+100mg/kg, respectively) significantly reduced the liver TBA values. Although hepatic cellular necrosis and fatty acid deposit were remarkably increased by $CCl_4$ intoxication, the concurrent administration of Ganoderma lucidum extract with glutathione (200+100mg/kg) reduced the pathological changes of parenchymal cell necrosis and fatty changes around centrilobalar area of the control. These findings indicate that the concurrent administrations of Ganoderma lucidum extract with glutathione showed better improvements than the individual administrations of them in all pathological aspects, in particular, against hepatitis and hepatic necrosis due to the cellular necrosis and fatty infiltration.
