Murata et al. (5) indicated that PGE2 is a principal mediator of inflammation in inflammatory diseases. Pong et al. (26) indicated that ROS induces oxidative damage in biomolecules and causes atherosclerosis, hypertension, diabetes and cancer. In the present
study, EEOA significantly reduced LPS-stimulated PGE2 and ROS production in RAW 264.7 cells (Figures 2 and 3).
