title: Chemopreventive property of Trichosanthes dioica root against 3-methylcholanthrene-induced carcinogenesis in albino mice.
abstract: This work reports the chemopreventive property of hydroalcoholic extract of the Trichosanthes dioica root (TDA) against 3-methylcholanthrene (3-MC)-induced carcinogenesis in Swiss albino mice. TDA was administered orally at 2 and 4 mg/kg for 45 days after 24 hours of a single subcutaneous administration of 3-MC (200 µg) in mice. The mice were observed for 15 weeks to record tumor incidence (fibrosarcoma) and survival. After 15 weeks the mice were killed for the evaluation of hematological profiles and hepatic biochemical parameters viz lipid peroxidation, reduced glutathione, glutathione-S-transferase, superoxide dismutase, and catalase. TDA treatment markedly reduced tumor incidence and prolonged the life span of sarcoma-bearing mice compared with 3-MC control mice. Hematological profiles of TDA-treated mice were restored significantly to normal levels. TDA treatment significantly modulated the liver biochemical parameters compared with 3-MC control. Therefore, TDA possesses remarkable cancer chemopreventive efficacy plausibly mediated by multiple mechanisms in Swiss albino mice.
