ABSTRAKT

This study assessed the chemopreventive potential of the Aegle marmelos plant on mouse skin tumorigenesis initiated by 7,12-dimethylbenz(a)anthracene (DMBA) and promoted by croton oil. A significant reduction in tumor incidence, tumor burden, tumor multiplicity, and the cumulative number of papillomas, along with a significant increase in the average latent period, was recorded in mice treated orally with A. marmelos extract (AME) at peri - and post-initiation phases (i.e., 7 days before DMBA application and continued until the end of the experiment) of papillomagenesis as compared with the carcinogen-treated controls. Furthermore, a significant increase in catalase activity, reduced glutathione and total proteins, and a depleted level of lipid peroxidation were observed in liver and skin of AME-treated animals as compared with the carcinogen-treated controls. Thus, the oral administration of AME, at a dose of 50 mg/kg body wt per day per animal, was found to be significantly effective in reducing skin tumors against chemical carcinogenesis in mice.
