Inhibitory effects of the methanol extract, hexane extract, methanol soluble fraction (MSF) and juice from 3 weeks fermented Kimchi on the tumor formation in sarcoma-180 cell transplanted mice were studied. Effects of the solvent extracts and juice of the Kimchi on the levels of lipid peroxide, glutathione, and the enzyme activities of the liver were also investigated in normal and sarcoma-180 cell transplanted mice. At 32 days following trans-plantation, MSF reduced the tumor formation by 54% compared with the control group, resulting in the smallest tumor weight. Lipid peroxided content in liver increased by the transplantation of sarcoma-180 cells. However, it decreased when MSF of Kimchi was treated to the mice. MSF also suppressed xanthine oxidase activity in cytosol of the liver cells in mice transplanted by sarcoma-180 cells. Kimchi extracts had no inhibitory effect on hepatic aminopyrine-N-demethylase activity in sarcoma-180 cell transplanted or normal mice. Methanol extract and hexane extract of Kimchi slightly increased hepatic glutathione contents in sarcoma-180 treated mice. The injection of MSF from Kimchi markedly increased glutathione levels in the liver of sarcoma-180 treated mice. The injection of MSF from Kimchi markedly increased glutathione levels in the liver of sarcoma-180 treated mice compared to the controls. The MSF recovered the activities of hepatic glutathione reductase and glutathione S-transferase that decreased by the injection of sarcoma-180 cells. These results showed that MSF of Kimchi could suppress the growth of tumors, inhibiting lipid peroxide production and xanthine oxidase activity, in mice. We also suggested that Kimchi extract might play an important role in the prevention of cancer by enhancement of the glutathione level itself as well as via glutathione reductase and glutathione S-transferase.

Anticarcinogenic activity of astaxanthin-contatining egg yolk(designate AEY) was investigated for mouse ascites carcinogenesis induced by mouse Sarcoma-180(S-180) cells. Female ICR mice(8mice/treatment, 7∼8weeks of age, 25±1g) were injected, i.p. with S-180 cells(1×107cell/ml PBS). Two days later, each mouse was given 0.1ml PBS containing AEY(10, 25 or 50ug/g body weight) or control egg yolk (CEY; 50ug/g body weight) every other day for 7 times. Control mice were only given 0.1ml S-180 cells and 0.1ml PBS. Mice treated with 25ug/g body weight of AEY showed 24.8 days of life, which was equivalent to 138% of control mice's life(180.0 dyas). Based on dose-dependant experiment of AFY, mice treated with 10ug/g body weight showed slightly longer life(19.4 days) relative to mice treated with control mice, and mice treated with 50ug/g body weight exhibited 21.9 days of life. Mice treated with any dose of AEY exhibited longer life than mice with CEY 50ug/g body weight. Body weight of mice treated with AEY was reduced relative to that of control mice CEY-treated mice. These results suggest than AEY inhibits the carcinogenesis of mouse ascites induced by S-180 cells.

Korean traditional fermented soy paste (doenjang) prolonged the life span of Balb/c mice injected with the sarcoma-180 cells. The activities of liver enzymes, such as xanthine oxidase, aminopyrine N-demethylase, aniline hydroxylase, ${\gamma}$-glutamylcysteine synthetase, glutathione reductase and glutathione S-transferase (GST), and the contents of lipid peroxide and glutathione were determined from the sarcoma-180 cell injected mice that were treated with methanol extracts from doenjang, miso and soybean. The content of lipid peroxide and the activity of xanthine oxidase in the liver of Balb/c mice which were increased by the transplantation of the sarcoma-180 cells were decreased by treatment with the methanol extract from doenjang. But the activities of aminopyrine N-dementhylase and aniline hydroxylase were not affected by the treatment of methanol extracts from doenjang to the mice injected with the sarcoma-180 cells. The content of glutathione, the activities of glutamylcysteine synthetase, glutathione reductase and glutathione S-transferase decreased by the injection of the sarcoma-180 were recovered considerably by the treatment of the methanol extract from doenjang.

Objectives : The anticancer response of three different types of water extracts of Zingiberaceae Curcuma longa L. tested for sarcoma 180. Only few studies carried out to investigate the effects of other contents of Curcuma longa L. in anticancer activities, therefore, in this study we have investigated the effects of other component then curcumin in Curcuma longa L. for anticancer a activities. Methods : Three different types of water extracts of Curcuma longa L. were prepared as follows. The sarcoma cells (S180) were maintained in Dulbecco's modified Eagle's medium (DMEM) and were seeded on 24-well cell culture cluster flat bottom with lid tissue culture treated non-pyrogenic polystyrene. The growth of sarcoma 180 was monitored for 1, 2 and 5 days. The sarcoma cells were pictured using inverted microscope and cell density was counted using hemocytometry. Results : After 5 days in the culture medium the results showed high growth of sarcoma 180 for control condition and the surface of CCP plates were fully covered with the cells. In case of medium in which the 10% of filtered water extract of Curcuma longa L. was added a very limited growth of sarcoma 180 was observed. The results were showed only small difference in cell density for two different concentrations of unfiltered water extracts of Curcuma longa L. whereasin case of filtered water extracts the control of sarcoma growth shows better result. Conclusion : The filtered water extracts showed the best result relatively to the unfiltered water extracts for two different concentrations. This indicates that the water extracts of Curcuma longa L. can have anticancer activities possibly without curcumin.

Background & Methods : In order to measure the acute and subacute toxicity of Vermilionum and it's anti-cancer effects, Sarcoma-180 abdominal cancer cells were injected intravenously. The following results were obtained after measuring the survival rate, toxicity of the NK cells, and IL- 2 productivity. Results : 1. It was impossible to measure $LD_{50}$ value in the acute toxicity test and no toxic effects were witnessed in the clinical observation. 2. No significant differences were shown in the weight changes between the experiment groups and the control group in the acute toxicity test. 3. No peculiar toxic effects were shown in the subacute toxicity test and the weight changes were insignificant between the experiment groups and the control group. 4. In measuring the survival rate after inducing abdominal cancer by Sarcoma-180, the experiment groups showed increased of 9.52% compared to the control group. 5. In measuring the activity of NK cells, no significant changes were shown between the experiment groups and the control group. 6. In measuring the productivity of IL-2, significant reduction was shown in the experiment groups compared to the normal group, but no significance was witnessed compared to the control group.

The present investigation was performed to elucidate the effect of pretreatment with low dose ultraviolet radiation (UV) and ethyl methanesulfonate (EMS) on cell survival by trypan blue dye exclusion method and plasma membrane glycoconjugates by lectin-cytochemistry in sarcoma 180 (S180) cells. Pretreatment with 2 J/$m^2$ UV or 2 mM EMS increased the percentage of survival of cells subsequently treated with high dose UV (10 or 20 J/$m^2$) or EMS (10 or 20 mM), respectively. Staining intensity of concanavalin A (Con A) of the cells pretreated with 2J/$m^2$ UV or 2 mM EMS and subsequently treated with 10 or 20 mM EMS was stronger than that of the cellstreated with 10 or 20 mM EMS. These results suggest that there is an adaptive response on cell survival to EMS or UV in S180 cells. And the results show a change in mannose-containing glycoconjugates of plasma membrane in S180 cells pretreated with EMS or UV and subsequently treated with EMS.

Effects of kochujang (Korean red pepper soybean paste) extracts on tumor formation, natural killer (NK) cell activity in spleen and glutathione S-transferase (GST) activity in liver were investigated in the sarcoma-180 cell transplanted mice. Inhibitory effects of these samples on lung metastasis of colon 26-M3.1 cells were also evaluated in the Balb/c mice. The injection of methanol extracts from traditional kochujang I (TK I, 0-day fermented), II (TKII, 6-month fermented), commercial kochujang (CK, 1-month fermented) and red pepper powder (RPP) significantly reduced tumor formation in Balb/c mice (p<0.05), TKII decreased tumor growth by 46% compared with control, resulting in the smallest tumor weight. The transplantation of sarcoma-180 cells increased the spleen/body weight ratio of Balb/c mice, while TKI and TKll significantly decreased this index (p<0.05). The effect of TKll and CK, fermented kochujang, on the NK cell activity of splenocytes was higher than that of sarcoma-180 cells transplanted control group. TK II recovered the activity of hepatic GST that was decreased by the transplantation of sarcoma- 180 cells in to the mice. All kochujang-treated mice had significantly fewer lung metastatic colonies than control mice. TKII was the most effective in inhibiting lung metastasis of colon 26-M3.1 cells. These results indicated that optimally ripened (6-month) TK had more suppressive effects on tumor formation and lung metastasis than RPP and kochujang without fermentation and commercially prepared kochujang in mice.

To investigate a possible biological activity of iridoid glucosides, six compounds, aucubin, catalpol, gardenoside, geniposide, rehmannioside and swertiamarin, were studied in relation with their potential influences in RNA and protein biosyntheses in murine tumor cell, sarcoma 180, in vitro. Protein biosynthesis was slightly inhibited by aucubin, gardenoside and swertiamarin. Degree of inhibition of RNA biosynthesis by those iridoid appeared to be more sensitive than that of protein biosynthesis. When aucubin was pretreated with ${\beta}-glucosidase$ to produce its genin form and the sarcoma 180 cells were exposed to this aucubigenin, the protein and RNA biosyntheses in the cells were profoundly inhibited. The results indicate that a biologically active from of iridoid compounds is the hydrolytic products of glycoside, i.e. genin form. It is also suggested that sarcoma 180 cells used in the experiments appear to lack of ${\beta}-glucosidase$, since the inhibitory actions of iridoid glucosides were so slight that those glucosides were not hydrolysed by the enzyme to their genin forms.

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.

This study was performed by the sister chromatid exchanges (SCEs) and micronuclei (MN) assays to investigate the adaptive response to ultraviolet light (UV) or ethyl methanesulfonate (EMS) in Chinese hamster ovary (CHO) and Sarcoma 180 (S180) cells. The pretreatment with 1 J/m$^2$ UV or 2 mM EMS decreased the frequency of SCEs induced by the treatment with 5 J/m$^2$ UV or 8 mM EMS in CHO cells. The pretreatment with UV (1 or 2 J/m$^2$) or EMS (1, 2 or 3 mM) did not affect the SCEs induced by the treatment with 7 J/m$^2$ UV or 10 mM EMS in S180 cells. On the other hand, the pretreatment with 1 J/m$^2$ UV or 2 mM EMS decreased the frequency of MN induced by the treatment with 5 J/m$^2$ UV or 8 mM EMS in CHO cells. The pretreatment with UV (1 or 2 J/m$^2$) or EMS (1, 2 or 3 mM) did not affect the frequency of MN induced by the treatment with 7 J/m$^2$ UV or 10 mM EMS in S180 cells. It is suggested that there are adaptive responses at the level of chromosome and micronuclei to UV and EMS in CHO cells.
