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.

Objectives : Sipjundaebo-tang is prepared by ten medical herbs that tone the blood and vital energy, and strengthen health. This prescription has long been used traditionally against anemia, anorexia, extreme exhausion and fatigue. The purpose of this thesis was to review the effects of Sipjundaebo-tang that are about immunopotentiation effects, antitumor activities and potentiation, detoxification of antitumor drugs Methods : We studied the research methods and results of experiments which were selected from Korean, Japaness and American theses were on the topic of immunopotentiation effects, antitumor activities and potentiation, detoxification of antitumor drugs from Sipjundaebo-tang Results and conclusions : Sipjundaebo-tang not only potentiates the effects of the combined use of chemotherapy, but also reduces and elimimate the immunotoxicity of antitumor drugs and radiotherapy. And it strengthen immunity and improve QOL, S/OH of cancer patients.

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.

To find antitumor components in the cultured mycelia of Lepiota procera, the proteinpolysaccharide obtained from the mycelia was subjected to DEAE - Sephadex A-50 column chromatography and Sepharose-4B gel filtration. Of the fractions, the purified Fraction C1 was named lepiotan and examined for antitumor activity against the solid form of sarcoma 180 in ICR mice. The inhibition ratio of lepiotan was 64% at the dose of 10 mg/kg/day for 10days. The chemical analysis of lepiotan showed 60% polysaccharide and 21 % protein. The polysaccharide moiety was found to be a heteromannoglucan which consisted of 46.3% glucose, 40.2% mannose and 11.0% fucose. When the antitumor component, Fraction A, was examined for immunopotentiation activity, it was found to increase the number of plaques in hemolytic plaque assay and to restore the immunity in the tumor-bearing mice up to 89.7% of the normal level. Also the antitumor acitivity was suppressed by the treatment with carrageenan, an antimacrophage agent. These results indicate that the antitumor activity was exerted through immunopotentiation, but not through direct cytotoxicity against the tumor.

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.
