  • Ganoderma lucidum 균사체의 액체 배양을 통하여 균체 내 sphingolipid를 분리 정제하여 그 구조를 규명하였으며, 피부보습을 비롯한 각종의 기능성을 탐색하여 화장품 소재 및 새로운 생물 산업소재의 이용가능성을 검토한 결과 배양한 Ganoderma lucidum로부터 일련의 과정을 통하여 crude sphingolipids를 얻고, methanol침전, Dowex AG $50W-X8(H^+\;form)$ cation exchange chromatography 및 preparative thin layer chromatography를 행하여 sphingolipids를 분리하였다. 생산량은 0.4g/L였으며, 수율은 1%였다. UV/VIS spectrum, FT-IR 및 1H-NMR 분석을 행하여 구조를 해석한 결과 phytosphingosine 유도체로 판명되었다. 이 phytosphingosine 유도체의 피부에 대한 보습효과는 $500{\mu}g/mL$ 이상의 농도에서 약 20% 정도 skinmate 값이 증가하였으며, $100{\mu}/mL$ 이상의 농도에서 거칠기 감소에 유의한 결과를 나타내었다. 이상의 결과로부터 Ganoderma lucidum이 생산하는 sphingolipids는 피부보습 및 거칠기 개선에 유의성이 확인되어 화장품 소재 및 새로운 생물 산업소재로서의 이용가능성이 높다고 할 수 있다.

  • A morphologically different form of Ganoderma lucidum was isolated from a cultivator's farm, and its optimum growth conditions were determined. A major difference in their morphology was color of fruit bodies. Fruit bodies of the mutant were white wherase those of normal Ganoderma lucidum were red. Spores of the mutant were global and mycelia were thin. Mycelial growth of this white mutant was favorable on potato sucrose agar medium, and optimum pH of the medium was 5.5.

  • Objectives : Ganoderma Lucidum has been used in traditional oriental medicine to treat various conditions including chronic fatigue and cough. This experimental study was designed to investigate the effects of yeast-fermented Ganoderma Lucidum extract on the fatigue of rats elicited by forced swimming. Materials and methods : The rat subjects were divided into 4 groups: normal group, control group administered with 0.9% normal saline, experimental I(Exp I) group administered with yeast-fermented Ganoderma lucidum extract and experimental II(Exp II) group administered with Ganoderma lucidum extract for 4 weeks. All the serum samples collected by heart puncture were used to measure biochemical factors such as glucose, lactate, lactate dehydrogenase(LDH), creatine kinase(CK), inorganic phosphorus, ammonia, total cholesterol(TC), triglycerides(TG), high-density lipoprotein(HDL), low-density lipoprotein(LDL), aspartate transaminase(AST), alanine transaminase(ALT). Results : 1. Weight change and swimming time were not significantly different in the experimental groups as compared with control group. 2. Lactate was significantly decreased in the experimental groups as compared with control group. Inorganic phosphorus was also significantly decreased in the Exp I group as compared with control group(p<0.05). 3. Serum lipid concentration was not significantly different in the experimental groups as compared with control group. 4. AST and ALT were significantly decrease in the experimental groups as compared with control group. Conclusions : Yeast-fermented Ganoderma lucidum in forced swimming rats would appear to reduce fatigue-related factors, AST, ALT of serum and promote anti-fatigue effect.

  • Doxorubicin is a powerful anticancer antibiotic extensively used in the treatment of several types of cancers. Long-term administration of this drug results in cumulative dose related cardiotoxicity due to enhanced production of free radicals leading to oxidative stress. Our earlier investigations have demonstrated significant antioxidant, anti-inflammatory and antitumour properties of Ganoderma lucidum extracts. We extended our investigations to evaluate the protective effect of Ganoderma lucidum extract against doxorubicin-induced cardiotoxicity. Administration of 3 doses of doxorubicin, 6 mg/kg body weights, i.p. per each dose, alternative days, showed dear signs of cardiotoxicity in rats. The drug enhanced serum creatine kinase (CK) activity and lipid peroxidation in tissue drastically. The drug also induced significant decrease in GSH level and activities of CAT, SOD and GPx. Administration of methanolic extract of G.lucidum (500 and 1,000 mg/kg body weight) significantly increased the level of GSH and activities of CAT, SOD and GPx. Activity of CK was significantly lowered in a dose dependent manner. The treatment also caused significant decrease in lipid peroxidation (MDA). The results thus indicated that methanolic extract of G.lucidum prevented oxidative stress caused by doxorubicin administration and the increase in serum CK activity and lipid peroxidation in the tissue. The experimental findings suggest the therapeutic potential of G.lucidum as adjuvant in cancer chemotherapy.

  • This study was carried out to screen the effective polymeric additives preventing wall growth during mycelial submerged cultivation of Ganoderma. lucidum. Effects of additives on mycelial growth and exo-polysaccharide (EPS) production in flask culture and jar fermenter system under 3 different pH processes were investigated, and changes of mycelial morphology were also examined. From flask culture of G. lucidum with additives of different concentrations, 0.1%(w/v) polyacrylic acid was effective for EPS production. As the polyacrylic acid of 0.1%(w/v) was added in medium, wall growth of G. lucidum mycelium grown in jar fermenter system could be protected. The addition of 0.1%(w/v) polyacrylic acid to medium was also improved the mycelial growth and EPS production in the later of submerged culture G. lucidum and no changes of mycelial morphology were observed.

  • This study was attempted to investigate the effect of Ganoderma lucidum extract on digestive system in experimental animals. Ganoderma lucidum water extract (GWE) was found to be promoted the charcol transport rate in the small intestine of mice. GWE exhibited the augmentation of spontaneus movement(motility) and contractile response(tension) in the ileum and colon strips of rabbit, and these action were inhibited by atropine. GWE given intraduodenaly(i.d.) exhibited the significant increase of gastric acid secretion in pylorus-ligated rats. GWE inhibited the formation of some experimental gastric ulcers(pylorus ligation ulcer i.d., indomethacin-induced ulcer p.o., i.d. and aspirin-induced ulcer p.o.) in rats, which are considered to relate to a protective action. GWE and EtOH extract(water soluble phase) were remarkably increase of bile excretion, when administration of i.d., intravenation(i.v.) and per os (p.o.) compared with normal-control group. GWE was observed antibacterial activity aginst several intestinal microoganisms and others bacteria in vitro test.

  • 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.

  • 호도에 4。Bx의 영지, 녹차 및 구기자물 추출물을 첨가하여 저장 안전성을 조사 비교한 결과는 다음과 같다. 1. 4。Bx로 제조한 천연 첨가물의 종류가 호도의 AV와 POV에 미치는 영향은 구기자가 가장 효과적이었으며, 영지<녹차의 순으로 나타났으나 저장기간 2개월까지 첨가물에 의한 영향은 거의 없었다. 저장기간이 증가함에 따라 첨가물에 의한 항산화효과가 증가되는 것으로 나타나 영지 첨가 시 2개월, 녹차 첨가 시 4개월, 구기자 첨가 시 8개월 연장하여 권장유통기간을 설정하여도 안전성을 기대할 수 있을 것으로 나타났다. 2. 4。Bx의 구기자는 가장 우수한 항산화력이 있어 호도의 저장 안전성을 높일 수 있는 것으로 생각되었으며 새로운 천연 항산화제로서의 응용이 가능함을 알 수 있었다.

  • 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.
