Abstract

Globally, colorectal cancer is the third commonest cancer in men since 1975.The present study focuses on the preventive strategies aimed at reducing the incidences and mortality of large bowel cancer. Chemoprevention of colon cancer appears to be a very realistic possibility because various intermediate stages have been identified preceding the development of malignant colonic tumors. Several studies have demonstrated that generous consumption of vegetables reduces the risk of colon cancer. This idea has prompted the present investigation to search for some novel plant products, which may have possible anticarcinogenic activity. It has already been proved from various experiments that chemopreventive agents, by virtue of their anti-oxidant, anti-inflammatory, anti-proliferative, apoptosis-inducing activity, act at various levels including molecular, cellular, tissue and organ levels to interfere with carcinogens. Previous studies from our laboratory have already reported the inhibitory effect of cinnamon and cardamom on azoxymethane induced colon carcinogenesis by virtue of their anti-inflammatory, anti-proliferative and pro-apoptotic activity. This particular experiment was carried out to assess the anti-oxidative potential of these spices. Aqueous suspensions of cinnamon and cardamom have been shown to enhance the level of detoxifying enzyme (GST activity) with simultaneous decrease in lipid peroxidation levels in the treatment groups when compared to that of the carcinogen control group.
