Evaluation the effect of topical and systemic celecoxib on serum antioxidant in induction of tongue neoplasm in rat

Abstract

Background : Oral cancer is one of the ten most frequent cancers worldwide. Reactive oxygen species (ROS), may play a key role in human cancer development. Inflammation occurs in cancers and increases oxidative stress agent COX2 over expression in oral premalignant lesions. Several studies showed COX2 inhibitors con improve antioxidant system. The aim of this study is the evaluation the effect of topical and systemic celecoxib on serum antioxidant in induction of tongue neoplasm in rat.
