  • To enhance the antimutagenic and anticancer activities of chinese cabbage kimchi, 13 kinds of kimchi, which were different kinds and levels of sub-ingredient added kimchi, were prepared and fermented at 15℃ for 1 day and then at 5℃ up to pH 4.3. The antimutagenic effects of the methanol extracts of the kimchi were studied by using Ames mutagenicity test in Salmonella typhimurium TA100 and SOS chromotest in E. coli PQ37. Among the kimchi samples, high ratio of red pepper powder(7%) and garlic(2.8% or 5.2%) added kimchi, 1% chinese pepper powder added kimchi and organic cultivated chinese cabbage kimchi significantly reduced(p<0.05) the mutagenicity induced by aflatoxin B1(AFB1) in Ames test and SOS response against N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) in SOS chromotest, and also the kimchi inhibited more effectively(p<0.05) the survival and growth of AGS human gastric adenocarcinoma cells than the standarized kimchi on the SRB assay, MTT assay and growth inhibition test. These results suggest that the antimutagenic and anticancer activites of kimchi can be increased by the sub-ingredients such as organic cultivated chinese cabbage, red pepper powder, garlic and chinese pepper powder.

  • The anticancer effect of methanol extracts from common Chinese cabbage kimchi(CC kimchi ) and organically cultivated Chinese cabbage kimchi (OC kimchi) was studied on the cell growth, MTT assay and SRB assay using AGS human gastric cancer cells. Methanol extracts from CC kimchi and OC kimchi exhibited the anticancer activites in vitro and in vivo. Methanol extract from 6 day-fermented CC kimchi and OC kimchi inhibited the growth of AGS cells by 55.2 and 60.7% , respectively. At MTT assay an dSRB assay, 6 day-fermented OC kimchi showed higher inhibition rate (MTT : 42%, SRB : 61%) than 6 day-fermented CC kimchi(MTT : 33%, SRB : 52%). Methanol extracts from 6-day fermented CC kimchi and OC reduced the tumor formation and prolonged the life span of sarcoma-180 cell injected Balb.c mouse. OC kimchi treated group resulted in the smaller tumor weight of 4.58$\pm$0.32g compared th the CC kimchi group of 5.40$\pm$0.78g and the control group of 7.50$\pm$0.54g and OC kimchi treted group (25.3 days) lived longest among control (20.2days ) and CC kimchi(23.5days) treted groups.

  • The study was performed using of ethanol and water extracts of Fatsia japonica Decne. et Planch. in anticancer and immune activities. All extracts of 1.0 $g/{\ell}$ concentration were increased in over 60% of the anticancer activites in A549 and MCF7 cells. Root barks inhibited 55%, 74% in A549 and MCF7 cell by adding ethanol extracts of $g/{\ell}$ concentration. The cytotoxicity of human lung nomal cell (HEL299) counted up to about 22% for ethanol extracts of root barks in 1 $g/{\ell}$ concentration. The activity of human immune T and B cells were increased up to $140{\sim}170%$ by adding ethanol extract of the root barks. Increasing trend of secretion of cytokine (IL-6, $TNF-{\alpha}$) from human B and T cell for 5 days cultivation has been abserved. From the results, the anticancer and immune-stimulatory activities of the roots extract were higher than the extracts of other parts.

  • In order to confirm the biological activities of rice bran and hull, total phenolic content, antioxidant and anticancer activities were examined in three rice varieties that have different seed coat colors such as brown, black, and purple. The antioxidant activity was measured by free radical scavenging assay including DPPH, $ABTS^+$ and reducing power activity. The anticancer activity was evaluated by WST assay with human HepG2 cell lines. As the result, Huegjinju, black seed coat rice, showed higher of the total phenolics contents in both bran and hull, than purple Jeojinju and brown Ilpum. In the antioxidant activity, Heugjinju showed the highest among the bran extracts, but the activities of hull extracts were similar in three varieties. In the anticancer activity to HepG2 cell line, the hull extract was 20% higher than that of bran extract in the average of three varieties. The hull extracts of Ilpum and Jeokjinju showed similar anticancer activites about 92%, and that of Heugjinju showed the lowest activity of 30.4%. The anticancer activities of hull extracts in three varieties showed positive correlation with total phenolics contents, DPPH radical scavenging activities and reducing power activities. In conclusion, the rice bran and hull showed potent antioxidant and anticancer activities varied in three varieties that have different seed coat colors.

  • Stems and roots of Acanthopanax koreanum Nakai were extracted with water and treated on immune cells in order to determine their immunomodulatory activites. Various Th-1 type cytokines were measured using ELISA including interleukin (IL)-2, IL-12, interferon-gamma (IFN-$gamma$), and tumor necrosis factor-alpha (TNF-$\alpha$) secreted by dendritic cells, T-cells, intestinal epithelial cells, natural killer cells, and macrophages. As a result, there was a significant increase in IL-12 and IFN-$\gamma$, secretion, but there was no change in the secretion of TNF-$alpha$. Additionally T-cells slightly increased the secretion of IL-2, but there was a significant increase of IL-2 in intestinal epithelial cells. Therefore, our results suggest that A. koreanum Nakai may act as an immunomodulator by stimulating the cell-mediated immunity which can help the immune system defend against infections or cancer cells.

  • We synthesized Pd(II) complexes containing sulfoxide and cycloamine series on the basis of the fact that many workers had the foresight to suggest anticancer activites using Pd(II) complexes with sulfur, nitrogen, or nucleic acid relatives as ligands particulary. The identification and characterization of these complexes are followed; content rates of atoms and molecular weights are confirmed by Elemental Analysis and Mass spectra, bonding of metal and ligands by UV-Vis. spectra and NMR spectra, and donor sites of ligands and configuration of complexes by IR spectra. These are yellow crystals, soluble in methanol and chloroform, and insoluble in H2O and the other common organic solvents.

  • This study was performed to investigate anticancer activities and immuno modulatory activities in the several parts of the A. mono and A. okamotoanum. The cytotoxicity of 1 $mg/m{\ell}$ of the water extracts on normal human lung cell(HEL299) was < 19.5%. The anticancer activity of all extracts were increased in over 55% against AGS (stomach adenocarcinoma), A549 (lung adenocarcinoma), Hep3B (liver adenocarcinoma, and MCF-7 (breast adenocarcinoma) cells. The growth of human immune B and T cells was improved of A. mono and A. okamotoanum in adding 1.0 $mg/m{\ell}$ concentration. The secretion of the IL-6 and $TNF-{\alpha}$ of human immune B and T cells was increased with all extracts of A. mono and A. okamotoanum. All extracts of. A. mono and A. okamotoanum increased NK cell growth. The results showed that the barks and woods extracts of A. mono and A. okamotoanum had useful biological activities. In addition, bark of A. okamotoanuim showed the highest anticancer and immune activities.

  • The antibacterial effect of methanol and water extracts from edible mushrooms on the growth of pathogenic bacteria (Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, Echerichia coli O-157, Listeria monocytogenes, Pseudomonas aeruginosa, Salmonella typhi) were investigated. The Lyophyllum cinerascens and Pleurotus ostreatus2 methanol extracts treated with 5.0 mg/disc showed the highest antimicrobial activity against 7 kinds of pathogenic bacteria. And methanol extracts of edible mushrooms showed higher antimicrobial activity against gram positive and gram negative microorganisms than water extracts. The methanol extracts of mushrooms revealed high inhibitive activites in cytotoxicity on human cancer HepG2 and HT-29 cells. The growth of cancer HepG2 and HT 29 cells which treated with 1 mg/mL of Cordyceps militaris and Sarcodon aspratus methanol extracts were strongly inhibited to $67\%$ and $81\%$ respectively. And most of the methanol extracts exhibited the stronger effects against these cells, at the same concentration, comparing with water extracts. Particularly, the methanol and water extracts of Cordyceps militaris, Agaricus blazei, Lyophyllum ulmarium, Ganoderma lucidum and Sarcodon aspratus have the strongest antitumoral effects on HepG2 and HT-29 cells. From these results, it is considered that wild mushrooms have stronger antimicrobial and in vitro cytotoxic effects.
