Aim & Method: The current study was designed to elucidate the protective effect of Syzygium cumini seed extract (SCE) on skin carcinogenesis induced by a single topical application of 7,12-dimethylbenz(a)anthracene (100 μg/100 μl of acetone) and 2 weeks later promoted by repeated application of croton oil (1% in acetone/three times a week) till the end of the experiment (16 weeks). Result: Oral administration of SCE at a dose of 125 mg/kg b.wt./day for 15 days at the peri-initiational stage (i.e., 7 days before & 7 days after DMBA application) and for 14 weeks at the promotional stage (i.e., from the time of croton oil application), revealed a significant reduction in lipid peroxidation (p<0.05-0.001) along with an elevation in the activities of enzymatic antioxidants (superoxide dismutase, p<0.05-0.001 & catalase, p<0.05-0.001), non-enzymatic antioxidant (reduced glutathione, p<0.05-0.01 & vitamin-C, p<0.01-0.001) and total proteins levels (p<0.01-0.001) when compared to the carcinogen treated control animals. Histopathological study revealed that dyskeratosis of the epidermis, deposition of keratinous pearl and epidermal hyperplasia in skin tumors of DMBA treated control and the same were found to be of lesser degree in both the SCE treated experimental animals. Conclusions: These results demonstrate that SCE ameliorate the DMBA/croton oil induced adverse biochemical and histopathological alterations during skin carcinogenesis in mice
