This study showed the increase of antitumor activities of water soluble E. sinica extract by nano-encapsulation process with lecithin. Five groups of lecithin only group (LO), lecithin nano-encapsulated E. sinica group (LE), E. sinica only group (EO), one negative control group (NCO) and positive control group (PCO) were set for several anticancer experiment and fed into Sarcoma-180 injected mice. The cytotoxicity of LE on the human normal kidney cell (HEK293) showed 14.8% lower than 19.2% of EO and 18.4% of LO. Growth of human liver carcinoma cell and human stomach carcinoma cell as representative of digestive system in vitro was inhibited up to about 85.1% and 87.3%, in adding 1.0 mg/$m{\ell}$ of LE, which values 15% higher than that from conventional EO. The survival rates of each mice group were 40%, 63%, 48%, 33% and 100%, respectively after 40 days of injecting Sarcoma-180. The increment of their body weights of the extract feeding groups was suppressed down to 10~15%, compared to the negative control. The nano-particles also reduced the hypertrophy of the internal organs such as spleen and liver down to 15~20%, compared to those as the other groups. Among them, LE effectively reduced the size of tumor form to 20%. From these results, in vitro and in vivo antitumor activities of E. sinica could be enhanced by using nano-encapsulation process with lecithin because of better permeation into the cancer cells by confocal observations.

To find antitumor components from higher fungi, the mycelia of Collybia confluens (Pers. ex Fr.) Kummer were cultured in artificial media. For efficient production of the mycelia, the influences of various modifications of culture conditions were examined. A water-soluble protein-bound polysaccharide fraction, Fr. A, was obtained from the mycelia by hot water extraction. When Fr. A was purified and fractionated by DEAE-cellulose and Sepbadex G-200 gel filtration chromatographies into four fractions which were designated B, C, C-I and C-II. The tumor inhibition ratios of these fractions ranged from 46% to 75% against the solid forms of sarcoma 180 in ICR mice at doses of 20 and 50 mg/kg/day when given intraperitoneally. Especially, Fr. C which was named Collyban(CB) exhibited a marked life-prolonging effect of the mice against ascitic forms of sarcoma 180 at a dose of 50 mg via i.p. administration. To extend spectra of the antitumor activities and eliminate the effects of allograft rejection, the characterization of antitumor effects of CB was performed in syngeneic host-tumor systems. It did not show any antitumor activity against L1210 murine leukemia in $CD_2Fl$ mice but prolonged their life span against ascitic forms of $MM_{46}$ carcinoma in $C_3H/He$ mice. Also it exhibited antitumor activity against human cervical cancer HeLa cells that were xenografted into nude mice having BALB/c genetic backgrounds by the i.p. injection at a dose of 100 mg/kg/day. In order to characterize the antitumor components, CB was examined by chemical analysis. It was acidic protein-bound polysaccharides composed of 31% polysaccharide, 27% protein and 3% hexosamine. CB was fractionated into two fractions, Fr. C-I(M.W.: 500 Kd) and Fr. C-II(M.W.:30 and 8 Kd) by Sephadex G-200 gel filtration chromatography.

The proteinpolysaccharides (PPS) from Polyporus umbellatus (P. umbellatus) screlotium is composed by 78.2% of saccharide, 16.8% of protein, and 4.0% of ash. PPS from P. umbellatus showed antitumor activities against 180 solid tumor in ICR mice at the concentration of 20-160 mg/kg/day. PPS from P. umbellatus inhibited cell viability to 47.4% and 45.0% in leukemia cell lines, L-1210 and K-562 cells at 50-400 $\mu\textrm{g}$/mL concentration, respectively. But the hall mark of cell apoptosis, DNA fragmentation was not observed at those concentration. 2.5-10.0% of PPS from P. umbellatus inhibited mutagenecity evoked by 2-nitrofluorene and sodium azide in Salmonella typhimurium TA 98 and TA 100. From these results, it is suggested that the PPS of P. umbellatus has antitumor and antimutagenic effect, and its cytotoxic effect may not be ascribed to the apoptosis.

To produce and characterize antineoplastic constituents in the submerged cultured­mycelia of Laccaria laccata, the mycelia were extracted with distilled water. Purification of the extract was carried out by acetone precipitation, by ion exchange chromatography using DEAE­Sephadex A-50, CM-Sephadex C-25 resins, and by gel filtration chromatography on Sephadex G-200. Each fraction obtained during the purification was examined for antineoplastic activity against sarcoma 180 in ICR mice. As the purification proceeded, the antineoplastic activity was markedly increased. The highly purified Fraction E showed 75% tumor inhibition ratio at a dose of 10mg/kg/day and contained 81% polysaccharide and 4% protein. The antitumor component of Fraction E stimulated an accumulation of peritoneal exudate cells including peritoneal macrophages, and is named laccaran.

This study was performed to investigate the effect of Bunsimgieum on antitumor effect after sarcoma-180 cells transplantation into peritoneal cavity or left groin and immune responses on the depressed immunity induced by methotrexate in mice. The Bunsimgieum extract of 10mg/kg was orally administered 14 days for antitumor effects and 21 days for immune responses. 50% inhibitory concentration($IC_{50}$) of SUN-1, SUN-C4, and SUN-396 cancer cell, mean sunvival days and body weight of tumor bearing mice, and growth of tumor mass for antitumor effect; delayed type hypersentivity, hemagglutinin titer, hemolysis titer, rosette forming cells, natured killer cell activity, lymphocyte transformation, productivity of interleukin-2, and phagocytic activity for their immune responses were measured in ICR mice. Significance in antitumor effect is noted in the enlongation of mean life days and inhibition of tumor growth(p<0.01, respectively). Significance of immune responses is also noted in hemolysis titer, lymphocyte transfumotion, IL-2 productivity, phagocytic activity, and natural killer cell activity at E/T ratio 100:1(p<0.01, respectively). Significant in rosette cell formation was seen at dosage of 20mg/kg(p<0.01). However, Difference of body weight as antitumor effect, delayed type hypersensitivity, and hemagglutinin titer were not shown significantly. According to the above results, it could be suggested that Bunsimgieum has prominent antitumor and immunity enhancing effect.

A red ginseng acidic polysaccharide(RGAP) with immunomodulating antitumor activities was isolated from Korean red ginseng, The molecular weight of RGAP was estimated to be 12-450 kDa by gel filtration chromatography, RGAP was found to increase survival rate and to inhibit of tumor growth significantly in a dose dependent manner in mice transplanted with tumor cells. RGAP significantly promoted nitric oxide(NO) production from peritoneal macrophages bothin vivo and in vitro. Western blot analysis exhibited a newly synthesized inducible nitric oxide synthase(iNOS) protein band in the RGAP treated group. It seems likely that immunomodulating antitumor activities of RGAP are mainly mediated by NO production of macrophage. RGAP was further purified by ultrafiltration and anion exchange chromatography on DEAE-sepharose, followed by gel filtration on Sephacryl S-300 to give an active fraction(GFP) with stronger NO production in murine macrophages. GFP increased survival rate ten times compared to RGAP in male ICR mice transplanted with sarcoma 180 and also showed more potent tumoricidal activities of natural killer cells than RGAP. Sugar $composition(mol\%)$ of GFP was found to be arabinose:rhamnose:xylose:galacturonic acid:mannose:galactose:glucose(10:9:1:25:8:20:27) by GC/MS. The results suggest that clinical trials of RGAP in immunotherapy against cancer are highly feasible.

A components of garlic (Allium sativum) have anti-proliferative effects against various types of cancer. We aimed to investigate the capacity of garlic compounds to anti-tumor on a various cancer cell lines. Fractionation of garlic extract, guided by antiproliferative activity against human gastric cancer (AGS) cells, has resulted in the isolation of N-benzyl-N-methyldecan-1-amine (NBNMA). We investigated the effect of newly isolated NBNMA from garlic cloves on the inhibition of the growth of CT-26, AGS, HepG2, HCT-116, MCF7, B16F10, and Sarcoma-180 cells for in vitro and CT-26 colon carcinoma cells in vivo. NBNMA exhibited an antiproliferative effect in CT-26 cells by apoptotic cell death. NBNMA exhibited down-regulation of anti-apoptotic Bcl-2 proteins and up-regulation of apoptotic Bad protein expression in western blot analyses. In addition, NBNMA meagre activated caspase 3 and caspase 9, initiator caspases of the extrinsic and intrinsic pathways of apoptosis. NBNMA treatment at a dose of 10 mg/kg for 21 days in experimental mice implanted with tumors resulted in significant reduction of the tumor weight (43%). NBNMA exhibited both in vitro and in vivo anticancer activity. These results indicate that NBNMA has promising potential to become a novel anticancer agent from garlic cloves for the treatment of colon carcinoma cancer.

The objective of the current study was to determine the effects of the extracts isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants on mouse splenocytes, B cells, and macrophages in vitro. The ethanol extracts B (EEB) directly induced the proliferation of spleen cells in a dose-dependent manner and increased IL-6, TNF-${\alpha}$, and IFN-${\gamma}$ synthesis. The EEB also increased the proliferation of B cells in a dose-dependent manner. The production of immunoglobulin M, G1, G2a, G2b, and IgG3 in the presence of the EEB increased progressively in the culture supernatant. When the EEB were used in macrophage cell line (RAW264.7) stimulation, there was a marked induction of NO synthesis in a dose-dependent manner and an increased IL-6, TNF-${\alpha}$, and GM-CSF synthesis. Intraperitoneal injection with EBB showed life prolongation effect of 16.1% in mice previously inoculated with sarcoma-180, respectively. These results suggest that the capacity of the EEB isolated from the fruit body of Flammulina velutipes cultivated with oriental herbal plants seems to act as a potent immunomodulator causing augmentation of immune cell activity, and with the absence of notable side-effects, Flammulina velutipes EEB could be used as a biological response modifier having possible therapeutic effects against immunological disorders. This study also showed that functional components of Flammulina velutipes were possibly improved by incorporating oriental herbal plants in a growth medium.
