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.

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.

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.

The polysaccharide fractions were isolated and purified from Phellodendron chinese SCHNEID, and antitumor activities using the melanoma B-16-derived metastatic tumors were examined at dosages of 2, 5 and 10 mg/100 g. F-7 and F-8 showed the highest tumor metastatic inhibitory activities (inhibition ratio 60 and 80% in 2 mg/100 g), and in dose of 5 mg/100 g, the inhibitory ratios were 85 and 70%, respectively. Furthermore, 10 mg/100 g of intraperitoneal (i.p.) injection gave 90 and 95% of inhibition. When the effects of polysaccharides on hypersensitivity were examined, the inhibitory activities were not markedly observed in oral administration, indicating that the polysaccharides are directly acting to immune system. Also, the polysaccharides increased the number of circulating blood leukocytes and total peritoneal exudate cells. Although implantation of tumor cells greatly decreased the productivity of antibody (antibody-mediated) and T lymphocyte reactivity (delayed-type) as 6.3 from 9.3 and 5.9 from 7.7, represented by the increase of footpad thickness, respectively. the polysaccharides elevated the reactivity of T lymphocyte in tumor-bearing mice, which were rapidly recovered by discontinuance of sample treatments. Especially, F-2, F-5, F-7 and F-8 remarkably recovered the decreased sensitivity. These results clearly indicated that the i.p. injection is much effective to suppress tumor growth than oral administration.

On the inter-order protoplast fusants of Lentinus edodes and Ganoderma lucidum was the antitumor activity test performed and the fusant P22 was selected. The hot water extract of the cultured mycelia of P22 were purified by DEAE-cellulose chromatographya and the resulting purified fraction was designated as P22A. It was found to be a proteoglycan whose molecular weight was 47 kDa. When examined for immunopotentiation activity, P22A increased the number of colony forming unit in the bone marrow stem cells to 3-folds. It also potentiated the secretion of nitric oxide in activated macrophages to 2-folds. In humoral immune response, it increased the activities of the alkaline phosphatase in differentiated B cells to 1.6-folds and the number of plaque forming cells to 1.8-folds. In cellular immune response, it restored the depressed response of delayed type hypersensitivity in tumor bearing mice to normal level. These results suggest that P22A have potential to restore the decreased immune activity of the tumor bearing mice to normal level.

Objectives : The aim of this study was to investigate the immunopotentiating activity of combine extract that Silkworm and Cinnamomum cassia. Recently, acute epidemic diseases such as cold and viral respiratory diseases have been emerging. So, interested in immunity enhancement has been increasing, and research on natural products to promote immunity activity has been actively conducted. Methods : To confirm the immunopotentiating activity effect, Silkworm (SW), Cinnamomum cassia (CC), and SWCC combined extracts were treated 14 days at 300 mg/kg/day. The changes of glutamic oxalacetic transaminase (GOT), glutamic pyruvate transaminase (GPT) in serum were analyzed after experiment. The changes in the total spleen cell number were measured. Immune cells in spleen were analyzed using fluorescence activated cell sorter (FACS). also, analyzed the expression of cytokines in spleen. Results : Total number of cells in the spleen and FACS analysis of T lymphocytes activated in the spleen showed that the SWCC combined treated group had much higher frequency of active cells than both single groups. The ratio of CD4+CD8+, CD4+CD69+ and CD4+CD25+ T cells in spleen, SWCC is higher than other groups except Nor in CD4+, CD4+CD69+, CD4+CD25+ T cells. The results of this study suggest that SWCC can help immune function via IL-2, IL-10, IL-12, IFN-${\gamma}$ cytokine production, increased T lymphocytes and splenocyte proliferation. Conclusion : Therefore, these results suggested that the SWCC combined extracts administration increase stronger immunity enhancement than when SW and CC adminstration.
