  • The polysaccharide fraction from the rhizome of Trichosanthes kirilowii (Cu-curbitaceae) showed marked antitumor and cytotoxic activity with immunopotentiating activity. It was evidenced by the increase in the number of circulating leucocytes and peritoneal exudate cells and the recovery of lowered antibody forming activity in mice. The polysaccharide was mainly composed of glucose, galactose, fructose, manmose and xylose and a small amount of protein.

  • 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.

  • This study was to evaluate the antitumor and immunopotentiation effects of Manda Enzyme (ME). Oral administration of ME (0.2ml/mouse) to tumor bearing mice significantly prolonged survival rate compared to the control group with the prolongation ratio of 40%. The inhibition ratios for the first and the second experiments were 51.8% and 26.4%, respectively. Only the spleen index was significantly increased in the MEF-treated group, but not in the control group. Gamma globulin level of the MEF-treated group was elevated when mice were injected with sarcoma-180 cells on the left groin. Activities of natural killer (NK) and lymphokineactivated killer (LAK) cells were observed by $^{51}Cr-release$ method. Activities of NK cell against YAC-1 cells were significantly increased in the MEF treated group. And LAK cell activities against P815 cells were also significantly increased in the experimental group. These observations, therefore, suggest that ME may have an anticancer effect and immunopotentiating effect in vivo.

  • The polysaccharide fraction from Taraxii Herba showed potent immunopotentiating activities with antitumor activities. The fraction having small amount of protein inhibited the growth of solid tumor and increased peritoneal exudate cells and immunoorgan weights in normal mice, and also increased hypersensitivities in tumor bearing mice.

  • 한국산 담자균류인 갓버섯 Lepiota procera의 균사를 액내 배양하여 항암성분인 단백성 다당체를 분리하였다. 이 성분은 DEAE-Sephadex A-50 이온교환수지와 Sepharose-4B gel Filtration을 이용하여 정제하여 Fraction C1을 얻었으며 이 Fr, Cr은 단백질과 다당체로 구성되어 있으며 항암 효과는 10mg/kg/day 투여군에서 64%의 저지유을 나타내었다. 이러한 항암작용의 기전을 밝히기 위한 연구의 일환으로 면역에 미치는 영향을 실험함 결과 이 단백다당체는 용혈반형성 세포수를 증가시켰으며, 저하된 지연성 과민반응을 회복시켰을 뿐만 아니라, carrageenan 투여에 의해 억제된 면역능을 다시 증강시켰음을 알 수 있었다. 이러한 결과들은 이 버섯의 항암작용이 세포독성에 의한 것이 아니라 종양에 대한 면역능을 강화시켜 발휘됨을 제시하고 있다.

  • To investigate antitumor component of Lyophyllum decastes, the aqueous extract of its shake-cultured mycelia was subjected to antitumor test against sarcoma 180 cells implanted in ICR mice. The extract showed an inhibition ratio of 65.4% and was found to consist of a polysaccharide moiety and a protein moiety. After purification with DEAE-Sephadex A-50 ion exchange chromatography, Fraction D showed the highest inhibition ratio of 75.7%. The antitumor constituent was examined for immunoaccelerating activity and was found to increase macrophage accumulation in the peritoneal cavity and plaque forming cells of the spleen cells. It was named lyophyllan after the genus name.

  • This paper presents a study for a development of the oriental medical treatment on the gastric disease caused by Helicobacter Pylori. Helicobacter Pylori is observed in stomach mucosa and it is caused gastric disease via various routes. Helicobacter Pylori is spread generally mouth to mouth by men. So it is related to personal health condition or life style. The treatment of Helicobacter Pylori is an antibiotic combination therapies, but it caused a problem of side effect and drug resistant. In the oriental medical treatment, an immunopotentiation reduces an infective rate of Helicobacter Pylori and prevents a progressive gastric disease.

  • Water-soluble pectins isolated from Trichosanthes Rhizoma and Taraxii Herba and their deproteinized polysaccharides were purified through DEAE cellulose column and were applied to immunopotentiating and antitumor studies to clarify the nature of their activities of our previous reports. As the results of works, the lectins and deproteinized polysaccharides increased the number of circulating leukocytes and total peritoneal cells. And they markedly elevated the lowered production of antibody and reactivity of T Iymphocyte in tumor-bearing mice, which were rapidly recovered by discontinuance of sample treatments. They also decreased the growth of Sarcoma 180 solid tumor in mice.

  • Antitumor effect of LC43, a protein-bound ploysaccharide (M.W. 43 kDa) that was purified from intergeneric protoplast fusant of Lentinus edodes and Coriolus versicolor, was elucidated against mouse sarcoma 180 cell in vitro and in vivo. By injecting LC43 into ICR mice bearing solid or ascitic sarcoma 180, tumor regression and survival rates were investigated. To examine the effects of LC43 on immunopotentiation activity. immunoorgan weight, B cell differentiation, T cell activity and macrophage activation were determined. LC43 showed antitumor effects against both solid tumor and ascitic tumor of sarcoma 180. It did not change significantly the immunoorgan weight but potentiated immune responses such as B cell differentiation and the release of superoxide anion from macrophages. These results suggest that the protein-bound polysaccharide of LC43 exhibited antitumor activities through the activation of immune-related cells and acted as an immunmodulator.
