Mushroom-derived ${\beta}$-glucan, a polysaccharide (GLP) isolated from the mycelium of Ganoderma lucidum, was previously shown to have inhibitory effects against tumor-bearing mice in vivo. We investigated the apoptotic effect of mushroom-derived ${\beta}$-glucan in a sarcoma-180 tumor cell- bearing mice model using an ELISA to determine the levels of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in the mice. The morphology of the tumor cells was assessed with transmission electron microscopy (TEM). GLP was injected into the tumor-bearing mice at a dose (i.p.) of 20 mg/kg for 10 days. After 30 days, the tumor mass from the inguinal region was collected, weighed, and assayed using TEM and a TNF-${\alpha}$ ELISA kit. The tumors that developed in the mice treated with GLP were 71.4% smaller than those in the control group, showing the ability of GLP to inhibit tumor growth. The levels of TNF-${\alpha}$ in the serum of the sarcoma-180 bearing mice were 12 times greater than in the serum of the nonbearing tumor mice. An ultrastructural study demonstrated that the GLP-treated sarcoma-180 tumor cells were condensed, with rearranged chromatin. In addition, the marginated chromatin in nucleus induced the nuclear compartment, and there were many vacuolization in the cell. GLP could be an effective apoptosis-inducing compound in sarcoma-type cancers.

Several studies have shown that extracts from yellow-green vegetables reveal antitumor activities. In the present study we investigated the effect of phytol in order to elucidate the immunological mechanism of antitumor activity of this substance. The results obtained from the experiment as follows: 1) Phytol showed cytotoxic effect on sarcoma 180 cells in vitro. 2) When phytol was injected into the peritoneal cavity of mice transplanted with sarcoma 180 cells, the average survival time (24.0 days) tended to increase as compared with the nontreated control (19.2 days). 3) When sarcoma 180 cells were injected subcutaneously into the right groin of mice, and then phytol was injected into the peritoneal cavity, the tumor inhibition ratio was 33%. 4) The natural killer(NK) cell activity was significantly augmented by phytol in vitro and in vivo. Similar augmentations of NK cell activity were obtained with culture supernatants of phytol exposed spleen cells and peripheral blood mononuiclear cells. 5) Phytol on the macrophage from peritoneal cavity showed a higher effectiveness in vivo than in vitro. These results indicate that phytol shows the inhibitory effect for growth of sarcoma 180 cells in vitro, also it can augment macrophage and NK cell activities in vivo.

The effect of skullcapflavon II, 5, 2'- dihydroxy-6, 7, 8, 6'-tetramethoxyflavone, on the growth of transplantable L 1210 and sarcoma 180 tumors in mice was studied. Intraperitional treatment of skullcapflavon II cased a significant (T/C = 166%) and a moderate (T/C = 122 %) prolongations of the life spans of ICR and $BDF_{1}$ mice respectively, which had been intraperitioneally inoculated with sarcoma 180 and L 1210 cells. Peritumoral injection of skullacapflavon II on the solid form of sarcoma 180 in mice inhibited the tumor growth strongly (Inhibition rate = 71%).

The anticancer effect of the bark of Broussonetia kazinoki root extracts (hexane. chloroform, ethylacetate, butanol, aqueous) were studied. The cytotoxicity by MTT assay and inhibitory effect on the growth of sarcoma 180 cells were tested in vitro. The reduction rate of the tumor formation and spleen/body weight rate on BALB/c mouse were tested in vivo. From the tests, each fraction showed the cytotoxic effect against the sarcoma 180 cells. In addition, as the concentration of the fractions increased, cytotoxic effect tendency increased as well. The cytotoxic rate of the hexane, chloroform, ethylacetate, butanol and aqueous fractions showed by 58.7%, 40.1%, 75.7%, 52.6% and 62.7% respectively after testing by MTT assay system. And sarcoma 180 cells were incubated for 6 days at 37$^{\circ}C$ with various concentrations of each fraction. As the incubation days go on, the number of cells increased, while the inhibition rate on the growth of sarcoma 180 cells were decreased. Especially the ethylacetate fraction at the concentration of 1.0 mg/ml strongly inhibited the growth of sarcoma 180 cells by 74% compared with the control for a day 37$^{\circ}C$ The hexane, chloroform, ethylacetate, butanol and aqueous fractions inhibited on the growth of sarcoma 180 cells by 31%, 19%, 60%, 30% and 42% respectively, when sarcoma 180 cells has been incubated for 6 days at 37$^{\circ}C$. The each fraction exhibited the antitumor effect in vivo. The ethylacetate fraction reduced the tumor formation by 41% compared with the control, when sarcoma 180 cells were injected subcutaneously into the left groin of BALB/c mice. Also spleen/body weight rate of ethylacetate fraction was increased by 2.10% compared with the control (1.08%). And it is considered that there would be no toxic effect caused by each fraction of body weight and organ as there was on more changes in mouse' weight compared with the control.

To develop Corni Fructus as a cancer preventive food material, the in vitro cytotoxicities and in vivo antitumor activities of various concentrations of 80% Corni Fructus ethanol extract (CFEE) were investigated using sarcoma-180 cancer cell. Viability was decreased and cell death rate was increased in both dose- and time-dependent manners in cells treated with CFEE at 10, 100, 300, and $500\;{\mu}g/mL$ concentrations for 24, 48, and 72 hr. Proliferation was also inhibited more than 60% in cells treated with CFEE at the $100\;{\mu}g/mL$ concentration for 48 hr. In addition, the morphology of cells treated with CFEE at the 100 and $500\;{\mu}g/mL$ concentrations was distorted with shrunken cell masses and lower cell numbers compared to the control cells. In the cells treated with CFEE, the formation of apoptotic bodies and nuclear condensation were observed in dose dependent manners. CFEE also increased DNA fragmentation values at the 100 and $500\;{\mu}g/mL$ concentrations. The apoptosis induced by CFEE was connected to the proteolytic activation of caspase-3. When CFEE was administered at 100 and 300 mg/kg, ip, for 7 consecutive days in mice inoculated with sarcoma-180 cancer cell, the life span of the mice was found to be longer than that of the control mice that did not receive the extract. These results suggest that Corni Fructus may be used as a potential cancer preventive food material.

Armillaria mellea, one of edible and medicinal mushroom belonging to Tricholomataceae of Basid-iomycota, has been known to have outstanding inhibitive effects on the sarcoma 180 and Erhrlich carcinoma of mice. Neutral salt 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 the mushroom. In vitro cytotoxicity tests, crude polysaccharide were not cytotoxic against cancer cell lines such as NIH3T3 and Sarcoma 180 at the concentration of $1000{\mu}g/ml$. Intraperitoneal injection with crude polysaccharides exhibited life prolongation effect of $60{\sim}67.5%$ in mice inoculated with Sarcoma 180, respectively. Fr, NaCl improved the immunopotentiation activity of B lymphocyte by increasing the alkaline phosphatase activity by $1.8{\sim}3.0$ folds, respectively. In case of Fr. NaCl, the numbers of peritoneal exudate cells and circulating leukocytes were increased by 10 and 2 folds, respectively.

This study was made to observe changes in hemograms of the Sarcoma-180 mouse treated with extracts of Poria cocos and Panax ginseng. The life span of the Sarcoma-180 mouse administered with the mixture of the extract of Panax ginseng with the extract of P. cocos and the extract of P. cocos was extended more than the non-treated group. In the body weight of the Sarcoma-180 mouse, the non-treated group was increased more than the normal group and the groups administered with the mixture of ginseng extract with hoelen extract and hoelen extract. In the numbers of white blood cell especially lymphocyte, the groups administered with the mixture of ginseng extract with hoelen extract and hoelen extract were similar to the normal group, but the non-treated group was decreased. The Hematocrit, mean corpuscular volume and mean corpuscular hemoglobin in the mice infected with Sarcoma-180 were not significantly different between the group treated with extracts of them and the non-treated group. In the distributions and sizes of white blood cell and platelet in the mice, the group administered with the Hoelen extract was similar to the normal group comparing to the non-treated group.

A protein-polysaccharide fraction of a Korean wild mushroom Psathyrella velutina, PVP, was prepared and its antitumor immunomodulatory activity was investigated. When PVP was administered once daily for seven days from day 1 to day 7 into male ICR mice implanted with 1 $\times$ 10$^{5}$ cells of sarcom 180 tumor cells into the peritoneum on day 4, it inhibited the growth of sarcoma 180 cells by 92.8%. In XTT assay, PVP also exhorted in vitro anti-proliferation activity on U-937, a human monoblastoid cell line, as well as sarcoma 180 cells. PVP showed marked stimulatory activity on the immune system in that it induced the accumulation of PEC (the stimulation index, Sl=4.90 at 100 mg/kg), stimulated the BALB/c mouse splenic lymphocytes to form lymphoblasts (Sl=5.75 at 100$\mu\textrm{g}$/ml), and upergulated the expression of CD25 molecules. All these results strongly support that PVP exhorts its antitumor activity through stimulation of the immune system as well as anti-proliferative activity on the tumor cells.

A hot water extract(HWE-P4) was separated from the fruit bodies of PMO-P4, and its antitumor and immunomodulatory activities against sarcoma-180 in ICR mice were investigated. The internal transcribed spacer(ITS) regions from PMO-P4 were amplified using polymerase chain reaction(PCR) and sequenced. The results revealed that PMO-P4 was belong to the Phellinus baumii. When oral administration at the dose of 160mg/kg/day in the mice until the end of the experiment with 2 week's pre-feeding of the HWE-P4, the survival rate of the mice was 152% for 50days after the inoculation of sarcoma-180 and the suppression rate of the tumor growth was 35.3%(p<0.05) for 28 days after inoculation of sarcoma-180. The HWE-P4 increased 71.4% of the CD4/CD8 ratio and 5-fold of the expression of CD25(IL-2 receptor chain) compared with the control. From these results, the antitumor activity of HWE-P4 is exerted through its immunomodulating activity on the host's immune system.
