To investigate the cytotoxicity of Korean traditional fermented soybean products using the MTT assay, we extracted soybean, Kanjang, Doenjang, Kochujang, and Chongkukjang with water, methanol, and hexane. Primary testing of cytotoxicity of 14 extracts was done for P388D1(mouse lympoid neoplasm) and L1210(mouse leukemia) cell lines. Doenjang methanol extract, Kochujang hexane extract, Chongkukjang methanol extract, and Chongkukjang hexane extract showed cytotoxicity of 86.1, 94.3, 83. 6, and 81.1%, respectively against P388D1, and showed cytotoxicity of 69.4, 96.9, 51.4, and 95.1%, respectively against L1210. All the other extracts showed less than 50% cytotoxicity. Methanol extracts of Doenjang and Chongkukjang showed dose-dependent cytotoxicity against P388DI, L1210, SNU-16 (human stomach cancer), HepG2(human hepatic cancer), WiDr(human colon cancer) cell lines, and IC$_{50}$ of Doenjang methanol extract was 67.7, 90.4, 1338.0, 706.4, and 371.2 $\mu$g/ml, respectively, and IC$_{50}$ of Chongkukjang methanol extract was 107.1, 228.3, 756.2, 1346.0, and 327.0 $\mu$g/ml, respectively.

Objective : This Study was to investigate effects of Takliikgi-tang on the anti-cancer and proliferation of immunocytes, nitric oxide (NO) production of peritoneal macrophages. Methods : We used Takliikgi-tang extract (TLT) with freeze-dried, 8weeks-old male mice and cancer cell lines (L1210, Sarcoma-180) for this Study. The cytotoxicity and proliferation of cells were tested using a colorimetric tetrazoliun assay (MTT assay). Results : 1. TLT was significantly showed cytotoxicity on the L1210, 5-180 cell lines. 2. TLT was significantly increased proliferation of thymocytes in vitro. 3. TLT was significantly increased proliferation of thymocytes and splenocytes in normal mice. 4. TLT was significantly increased NO production from peritoneal macrophages in normal mice. 5. TLT was significantly decreased proliferation of L1210 cells in L1210 cells transplanted mice. 6. TLT was significantly increased proliferation of thymocytes and splenocytes by all-dosage in L1210 cells transplanted mice. 7. TLT was significantly increased NO production from peritoneal macrophages in L1210 cells transplanted mice.

The methanol extracts prepared from ten kinds of culinary herbs were investigated for the cytotoxcic effect againt L1210 cancer cells and the mode of action. The substantial cytotoxic effects were observed in all cases with the most prominent effect demonstrated by lemon verbena extract showing $87{\pm}4.1%$ cytotoxicity with $100{\mu}g/ml$ concentration and 3 days culture period. The cytotoxic effect was found to be dose and culture period dependent. With respect to the mechanism of the cytotoxicity, the augmented generation of $O_2{^-}ion$ and the dramatically escalated activities of antioxidant enzymes such as superoxide dismutase(SOD) and glutathione peroixdase (GPx) with addition of the herb methanol extractw suggested that there would be the involvement of reactive oxygen species (ROS) metabolism in the course of L1210 cancer cell death by the mothanol extract of the edible herbs.

Chitosan is a depolymerized and partially deacetylated derivative of chitin. We investigated the cytotoxicity of chitosan in cancer cell lines, such as P388, L1210, HCT-15, SK-HepG-1 and mouse splenocytes as a normal cell by MTT assay. To clarify whether chitosan enhances cytotoxicity of anticancer drugs, we also examined the cytotoxicity of combined treatment with chitosan and anticancer drugs, such as cisplatin, mitomycin C, and 5-fluorouracil in cancer cell lines in vitro. Chitosan ($37.5\;{\mu}g/mL,\;75\;{\mu}g/mL,\;112.5\;{\mu}g/mL,\;and\;150\;{\mu}g/mL$) showed concentration-dependent cytotoxicity in the cancer cell lines. In addition, chitosan showed relatively lower cytotoxicity in normal cells than in the cancer cell lines. Particularly, this trend was significant at high doses of chitosan, i.e. $112.5\;{\mu}g/mL,\;and\;150\;{\mu}g/mL$. Thus, these results suggest that chitosan may selectively induce the growth inhibition in cancer cell lines, compared to normal cells. Furthermore. the co-treatment of chitosan and anticancer drugs exhibited an apparant synergistic cytotoxicity in murine lymphoma cell lines, i.e. P388 and L1210 at $37.5\;{\mu}g/mL$ of chitosan rather than at $75\;{\mu}g/mL$ of chitosan, but such phenomenon could not be observed in solid tumor cell lines, i.e. HCT-15 and SK-HepG-1. However, chitosan did'nt reduced the cytotoxicity against normal mouse splenocytes induced by anticancer drugs. Therefore, it is concluded that the combination of chitosan and anticancer drugs might be useful for the cancer chemotherapy.

The purpose of this research was to investigate the effects of Coix Lachryma-Jobi L. var. Ma-yuen Stapf. on the proliferation of L1210 cells and immune cells. The hexane fraction of Coix Lachryma-Jobi decreased the proliferation of L1210 cells and induced DNA fragmentation of L1210 cells. Also, the fraction decreased the cell viability of murine thymocytes and splenocytes, but increased the phagocytic activity of murine peritoneal macrophages. In addition, fatty acids and fatty acid methyl esters decreased the proliferation of L1210 cells and induced DNA fragmentation of L1210 cells. The main components of the fraction are fatty acid and their derivatives. These results indicate that Coix Lachryma-Jobi has a cytotoxicity on tumor cells and immune cells.
