  • 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.

  • 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.

  • The changes of morphology and protein pattern of sarcoma 180 cells treated with or without trannins extracted from persimmon leaves were evaluated by light microscopy, electrophoresis and Western blotting. The sarcoma 180 cells treated with tannins increased the amount of proteins which presumably were intermediate filament cytokeratins detected by electrophoresis and Western blot. Tannins was indirectly cytotoxic to the sarcoma 180 cells and increased the intermediate filament protein level in the cells.

  • 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 mutant herpes simplex virus 1, mtHSV, was constructed by inserting the E. coli beta-galactosidase gene into the loci of icp34.5, the apoptosis-inhibiting gene of HSV. The mtHSV replicated in and lysed U251 (human glioma cells), EJ (human bladder cells), and S-180 (mice sarcoma cells), but not Wish (human amnion cells) cells. With its intact tk (thymidine kinase) gene, mtHSV exhibited susceptibility to acyclovir (ACV), which provided an approach to control viral replication. An in vivo test with mtHSV was conducted in immune-competent mice bearing sarcoma S-180 tumors, which were treated with a single intratumoral injection of mtHSV or PBS. Tumor dimensions then were measured at serial time points, and the tumor volumes were calculated. Sarcoma growth was significantly inhibited with prolonged time and reduced tumor volume. There was microscopic evidence of necrosis of tumors in treated mice, whereas no damage was found in other organs. Immunohistochemical staining revealed that virus replication was exclusively confined to the treated tumor cells. HSV-1 DNA was detected in tumors, but not in the other organs by a polymerase chain reaction analysis. From these experiments, we concluded that mtHSV should be a safe and promising oncolytic agent for cancer treatment.

  • 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.
