This study was investigated on the antitumor of protein-polysaccharide fraction(PPF) extracted from seaweeds such as sea-staghorn and laver toward sarcoma-180 cells. In the PPF extracted from these sewaweeds, the polysaccharide contents of sea-staghorn and laver were $62.26\%$ and $65.78\%$, respectively. The highest levels of polysaccharides found in seaweeds was fructose. The major amino acids were aspartic acid, glutamic acid, glycine and cystein. The solid tumor growth inhibition showed the highest level of $53.30\%$ when 50mg/kg sea-staghorn was administrated. The life prolongation effect was $17.35\%$ at 50 mg/kg of laver. In the effects of immunologic activity, when 100mg/kg sea-staghorn was administrated, the number of circulating leucocyte showed the highest level of $82.23\%$ but decreased leucocyte for prolonged times. The number of total peritoneal exudate cells of the sea-staghorn administerated group was increased significantly in comparison with the control group. The hematobiolgoical analysis of the experimental group was similar with that of the control group. This experiments indicated that hemeastasis still maintained nor-mal state and not showed any harmful effects in normal mice.

Oudemansiella radicata, edible and medicinal mushroom belonging to Agaricales of Basidiomycota, has been known to exhibit outstanding curative effects on the fungal infection and hypertension caused by high blood pressure. Neutral saline soluble (0.9% NaCl), hot water soluble and methanol soluble substances (hereinafter referred to Fr, NaCl, Fr. HW and Fr. MeOH, respectively) were extracted from fruiting body of the mushroom. In vitro cytotoxicity test showed that Fr. NaCl was not cytotoxic against NIH3T3 and Sarcoma 180 at the concentration of $10{\sim}1,000\;{\mu}g/ml$. Intraperitoneal injection with Fr. NaCl exhibited antitumor activity with life prolongation effect of $42.9{\sim}66.7%$ in mice inoculated with Sarcoma 180. Fr. NaCl improved the immunopotentiating activity of B lymphocyte by increasing the alkaline phosphatase activity by $1.4{\sim}3$ folds compared with controlled and LPS groups, respectively. Intraperitoneal injection with Fr. MeOH increased the numbers of peritoneal exudate cells and circulating leukocytes by 3.5 and 2.5 folds, respectively. Therefore, the antitumor effect exhibited on mouse Sarcoma 180 cells was likely due to immune-modulating activity of crude polysaccharides extracted from fruiting body of O. radicata.

Neutral salt soluble [0.9% NaCl (Fr. NaCl)], hot water soluble (Fr. HW) and methanol soluble (Fr. MeOH) materials were extracted from Paecilomyces sinclairii. In vitro cytotoxicity tests. Fr. HW was not cytotoxic against MH3T3, Sarcoma 180 and HepG2 cancer cell lines at the concentration of $0{\sim}2,000\;{\mu}g/ml$, while HT-29 cell line was cytotoxic at the concentration of $100\;{\mu}g/ml$. Fr. NaCl and Fr. MeOH were slightly cytotoxic to the cell lines. Intraperitoneal injection with Fr. NaCl and Fr. MeOH exhibited antitumor activity with life prolongation effect of 32.3% in mice inoculated with Sarcoma 180. Fr. NaCl improved proliferation of spleen cells and the immunopotentiation activity of B lymphocyte by increasing spleen cell numbers and the alkaline phosphatase activity by $2.4{\sim}2.6\;and\;2.7{\sim}3.9$ folds, respectively. Fr. NaCl generated $89\;{\mu}M$ of nitric oxide (NO) when cultured with RAW 264.7, a mouse macrophage cell line, at the concentration of $50\;{\mu}g/ml$, while iipopolysaccharide, a positive control, produced $79\;{\mu}M$. The Fr. NaCl showed the hightest antitumor effect and activation of B lymphocytes and macrophage. From these results, antitumor effect of P. sinclaitii was likely due to immunopotentiation activity.

Immunostimulating effects of lactic acid bacteria as biological response modifier is a subject of growing interest, but the knowledge of these focused on some bacteria as Lactobacillus and Bifidobacterium. In this study, we investigated the effects of Pediococcus pentosaceus EROM101 on the immunostimulating and anti-cancer activity in murine model. P. pentosaceus was mainly found in Kimchi and fermented sea food and is facultatively anaerobic, catalase-netative, gram-positive cocci arranged in pairs, tetrads and clusters. The immunostimulating effects of P. pentosaceus EROM101 were evaluated using IgA production assay of Peyer's patch and proliferation assay of exudated immune cells of Balb/C mice fed P. pentosaceus EROM101 for 3 weeks. The macrophage and splenocyte proliferation were enhanced by orally administrated of P. pentosaceus EROM101. Also, IgA production in Peyer's patch increased by P. pentosaceus EROM101. Anti-cancer activity of P. pentosaceus EROM101 was appeared in Sarcoma 180 tumor-bearing ICR mice. However, this bacterium lysate itself appeared to have noncytotoxic substance against Sarcoma 180 cell in vitro. These results suggested that P. pentosaceus EROM101 reinforce immune system and therefore was revealed to be anti-cancer activity in mice.

The effects of mushrooms such as Lentinus edodes and Pleurotus ostreatus on anti-cancer activity through in vivo and in vitro experiments were powders of protein-bound polysaccharides in mushrooms were solubilized in 0, 5, 25 mg/kg saline, respectively and were used in vitro experiments. The in vivo experiments were carried out as followed: i) anti-cancer activities on Leukemia $(L_{1210})$, Hepatlicus cancer $(H_{22})$ and Sarcoma180/(S180), and ii) the effect on immune system through changes in intestine weight and the number of hemolytic plague forming cells. Protein-bound polysaccharides of all showed anti-cancer activity on $L_{1210}$ and fruit body of Lentinus edodes 25 mg/kg treatment group showed the highest inhibition rate (86%). Pleurotus ostreatus mycelial in medium of cultivate 25 mg/kg treatment. Fruid body of Lentinus edodes 25 mg/kg treatment group showed the highest inhibition rate (86% and 71%, respectively) on $H_{22}$ among them. The inhibition rates of fruit body and mycelial of Lentinus edodes 25 mg/kg treatment groups on S180 were 33.9% and 30.9%, respectively. Each samples of 50, 100, 200, $400\;{\mu}g/{\mu}L$ on in vitro cell toxicity test did not show significantly different cell death rates at P<0.05. In immune test, weights of liver and spleen were increased according to increase in conc. but were not significantly different at P<0.05. The weights of thymus were heavy in fruit body and mycelial of Lentinus edodes treatment group but were not significantly different at P<0.05. Hemolytic plague forming cells with antibody formation capability were significantly high in fruit body and mycelial of Lentinus edodes treatment samples.

The Chaga mushroom (Inonotus obliquus) has been used in folk medicine to treat cancers. However, limited information exists on the underlying anticancer effects of the major component of I. obliquus in vivo. We hypothesize that the pure compounds ($3{\beta}$-hydroxy-lanosta-8,24-dien-21-al, inotodiol and lanosterol, respectively) separated from I. obliquus would inhibit tumor growth in Balbc/c mice bearing Sarcoma-180 cells (S-180) in vivo and growth of human carcinoma cells in vitro. To test this hypothesis, the growth inhibition of each subfraction isolated from I. obliquus on human carcinoma cell lines (lung carcinoma A-549 cells, stomach adenocarcinoma AGS cells, breast adenocarcinoma MCF-7 cells, and cervical adenocarcinoma HeLa cells) was tested in vitro. Then, after S-180 implantation, the mice were fed a normal chow supplemented with 0, 0.1 or 0.2 mg of subfraction 1, 2 or 3 per mouse per day. All of the subfractions isolated from I. obliquus showed significant cytotoxic activity against the selected cancer cell lines in vitro. Subfraction 1 was more active than subfraction 2 and subfraction 3 against the A549, AGS and MCF-7 cancer cell lines in vitro. In in vivo results, subfraction 1 isolated from I. obliquus at concentrations of 0.1 and 0.2 mg/mouse per day significantly decreased tumor volume by 23.96% and 33.71%, respectively, as compared with the control. Subfractions 2 and 3 also significantly inhibited tumor growth in mice bearing S-180 as compared with the control mouse tumor. Subfraction 1 isolated from I. obliquus showed greater inhibition of tumor growth than subfractions 2 and 3, which agrees well with the in vitro results. The results suggest that I. obliquus and its compounds in these subfractions isolated from I. obliquus could be used as natural anticancer ingredients in the food and/or pharmaceutical industry.
