| Popis: | Introduction: Vanillic acid, a naturally occurring bioactive substance, possesses diverse pharmacological potential including free radical scavenging and anticancer properties. Excessive generation of Reactive Oxygen Species (ROS) and insufficient antioxidant potential has been involved in numerous pathological disorders, including cancer. Aim: To explore the anti-lipid peroxidative and antioxidant efficacy of vanillic acid in Dimethylbenz[a]Anthracene (DMBA) induced oral carcinogenesis. Materials and Methods: Topical application of DMBA for 14 weeks in the buccal pouch of hamsters resulted in well developed oral squamous cell carcinoma. Vanillic acid at a dosage of 200 mg/kg body weight was orally administrated to the hamsters for 14 weeks. The status of lipid peroxidation and antioxidants were measured in the plasma and buccal mucosa of hamsters using specific colorimetric methods. Results: Altered levels of lipid peroxidation by-products {Thiobarbituric Acid Reactive Substances (TBARS)} and disturbances in antioxidants status {Superoxide Dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx), vitamin E, vitamin C and reduced Glutathione (GSH)} were observed in the plasma and buccal mucosa tissues of hamsters treated with DMBA alone. Vanillic acid (200 mg/kg bw p.o) significantly restored the above mentioned plasma and buccal mucosa biochemical variables to near normal range in DMBA treated hamsters. Conclusion: Present findings thus confirm the anti-lipid peroxidative and antioxidant efficacy of vanillic acid in DMBA induced hamster buccal pouch carcinogenesis. |
