(i) In the H22 hepatoma-transplanting test, MCP had antitumor action, but MCP residue did not show such action; 5-FU appeared to have more potent antitumor activities and more harmful effects than MCP. (ii) In the micronucleus (MN) test, MCP significantly decreased MN frequency. (iii) In the cancer cell culture systems, the MCP fat-soluble extract revealed inhibitory effects on the growth and proliferation of the human hepatoma and the gastric cancer cells in a dose-response manner. (iv) In the colony formation test, MCP also altered the morphology of human gastric cancer cells. It was suggested that MCP could be consumed not only by healthy subJects for cancer prevention but also by patients with cancer as supplernentary treatrnent in combination with anticarcinogenic drug such as 5-FU, cyclophosphamide (CP)展开更多

The formalin pain model was used to evaluate the antinociceptive effects of the treatments. For anti-inflammatory effect, acute(one hour after injection) and chronic(during a week after injection)paw inflammation was measured after subcutaneous injection of 2.5% formalin in the hindpaw.Finally, tissue samples from all groups were prepared for histopathological studies.Results: The combined extract significantly inhibited the nociception in the acute phase of the formalin test(P < 0.001). In the chronic phase, all the extracts and SS had significant analgesic effect(P < 0.001).Analgesic activity of the combined extract was significantly stronger than SS(P < 0.01). In the acute inflammation model, M. sylvestris, C. carvi and the combined drug had significant inhibitory effects against paw edema(P < 0.05). All extracts, individually and in combination, significantly alleviated chronic paw inflammation(P < 0.01). The combined extract had much more anti-inflammatory activity than SS(P < 0.05). Histopathological results indicated improvement and reduction of inflammatory factors in the treatment groups.Conclusion: M. sylvestris, C. carvi and M. sativa have analgesic and anti-inflammatory properties.Potentially, each of these extracts or a mixture of them might be a valuable alternative drug to control pain and inflammation.展开更多
