This study was investigated on the antitumor effects of protein-polysaccharide fraction(PPF) extracted from seaweeds such as sea-lettuce and gonpi toward sarcoma-180 cells. In the PPF extracted from these seaweeds, the polysaccharide contents of sea-lettrce and gonpi were 52.20% and 48.16%, respectively. The highest levels of constituents monosaccharides 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 64.55% when 50mg/kg sea-lettuce was administerated. The life prolongation effect was 18.31% at 50mg/kg of gonpi. In the effects of immunologic activity, when 50mg/kg sea-lettuce was administrated, the number of circulating leucocyte showed the highest level (65.11%). The number of total peritoneal exudate cells of the sea-lettuce administerated group was increased significantly in comparison with the control group. The hematological analysis of the experimental group was similar with that of the control group.

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.

This study was conducted to investigate the effect of mycelia extracts of mushroom-cultured ginseng by-product on electron donating ability and proliferation of hepatic cancer cell (Hep3B) lines and sarcoma 180(S-180). The ginseng by-product was obtained from ginseng residues generated in processing of ginseng water extract. Mushroom strains used for preparation of mushroom mycelia cultured with ginseng residue were Phellinus linteus, Ganoderma lucidum, Coriolus versicolor and Lentinus edodes. The electron donating abilities of the test samples were increased in a dose-dependent manner in the range of 500ppm to 10,000ppm, and Coriolus versicolor extract showed the most potent activity among four mycelia extracts. In an anti-cancer test using Hep3B cells, ethanol extract showed higher antiproliferating effect than water extract. Ethanol extract of Lentinus edodes showed growth-inhibitory effect of 99.1% at 5,000ppm. All of mycelia extracts of mushroom showed the tumor suppressive effect in mice injected with S-180 cells. The growth­inhibitoy rates against tumor cells were 59% for Phellinus linteus, 61% for Ganoderma lucidum, 65% for Coriolus versicolor, 56% for Lentinus edodes. In conclusion, these results suggest that mycelia extracts of mushroom cultured with ginseng by-product have an antiproliferating effect against Hep3B cell and S-180 tumor cells.

The anticancer activities of petroleum ether extract of Panax ginseng root(crude GX) and its partially purified fraction from silicic acid column chromatography (7:3 GX) were studied with Sarcoma 180(S-180) or Walker carcinosarcoma 256 (Walker 256) in vivo and with L1210 leukemic lympocyte in vitro. Potential cytotoxic activities of the crude GX and against L1210 cells were compared with those of 5-Fluorouracil (5-FU) and saponin derivatives (Panax-diol, Panax-triol, Diol saponin, Triol saponin) in vitro. In order to observe the physiological effects of the crude GX and 7:3 GX on the animals with cancer, hemoglobin(Hb), red blood cell(R.B.C) and white blood cell after treatment with each GX in comparison with corresponding control groups, respectively. The anticancer effects of the crude GX and 7:3 GX were estimated by measuring the survival time of S-180 bearing mice after treatment with them. The experimental results obtained are summarized as follows; 1. The one unit of cytotoxic activity against L1210 cells was equivalent to 2.54$\mu\textrm{g}$ and 0.88$\mu\textrm{g}$of the crude GX and 7:3 GX per ml of culture medium, respectively. 2. The cytotoxic activities of Panax-diol, Panax=triol, Diol saponin and triol saponin against L1210 cells were not detected. 3. The anticancer activities of 5-FU against L1210, S-180 and Walker 256 were very effective in vivo and vitro tests. 4. The significantly increased W.B.C values of mice after inoculation with S-180 cells were reduced to normal range by the crude GX treatment. 5. The significantly decreased Hb values of rats after inoculation with Walker 256 were recovered to normal range by oral administration of the crude GX. 6. The survival times of mice inoculated with S-180 cells were extended about 1.5 to 2 times by the 7:3 GX treatment compared with their control group.

This study was conducted to investigate the effect of mycelia of Lentinus edoes mushroom-cultured Astragalus membranaceus Bunge (LAM) on proliferation of cancer cell lines (Hep3B, MCF-7 and HeLa), sarcoma 180 (S-180), and anti-allergy. In an anti-cancer test using Hep3B (hepatic cancer cell), MCF-7 (breast cancer cell) and HeLa (uterine cancer cell), LAM extract showed higher antiproliferating effect than that of Astragalus membranaceus Bunge (AM) extract. In an anti-cancer testing using Hep3B cells and MCF-7 cells, LAM extract showed growth-inhibitory effect of 65.23% at 3 mg/mL and 69.23% at 5 mg/mL, respectively. In an anti-cancer testing using HeLa cells, LAM extract showed growth-inhibitory effect of 42.01% at 5 mg/mL. In addition, LAM showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitory rates against tumor cells were 47% for LAM and 37% for AM. LAM inhibited histamine release from rat peritoneal mast cells activated by compound 48/80. These results suggest that Lentinus edodes mushroom-cultured herb has an antiproliferating effect against cancer cell lines (Hep3B, MCF-7 and HeLa), S-180 tumor and will be beneficial in the treatment of allergic reaction.

Young radishes (YR, yeolmu in Korean) were cultivated in the soil with and without sulfur. Young radish kimchi-general (YR kimchi-G) was prepared with YR commonly cultivated in the soil without sulfur. Young radish kimchl-sulfur (YR kimchi-S) and young radish kimchi-sulfur with lime mortar (YR kimchi-SL) were prepared with the YR cultivated in the soil with sulfur an4 sulfur added lime mortar on it respectively. Antitumor effects of methanol extracts from the YR kimchis were investigated in sarcoma-180 tumor cell transplanted mice. The solid tumor growth was significantly inhibited by the YR kimchi-SL prepared with YR grown in the soil with sulfur (p < 0.05). The treatment of the methanol extracts from YR kimchi-S and -SL increased the glutathione S-transferase activities and glutathione contents in the livers, compared to thlose of YR kimchi-G and the control. One of the antitumor effects by the YR kimchis was due to the increased the glutathione levels and the glutathione S-transferase activity which is phase 2 enzyme. These results also suggested that the antitumor effects of YR kimchi can be enhanced by using YR cultivated differently in the presence of sulfur that can help to produce sulfur-containing compounds in YR.
