영문 초록

The aim of the present study is to investigate the anti-inflammatory effect of a Rice Bran Ethanol Extract (RBE). Inflammation, such as a bacterial infection in vivo metabolites, such as external stimuli or internal stimuli to the defense mechanisms of the biological tissue a variety of intracellular regulatory factors deulin inflammatory TNF-α, IL-1β, IL-6, IL-8, such as proinflammatory cytokines, prostagrandin, lysosomal enzyme, free radicals are involved in a variety of mediators. The present study was designed to determine the effect of the RBE on pro-inflammatory factors such as NO, iNOS expression and TNF-α, IL-1β, IL-6 in lipopolysaccharide (LPS) - stimulated RAW264.7 macrophages cells. The cell toxicity was determined by MTS assay. To evaluate of anti-inflammatory effect of RBE, amount of NO was measured using the NO detection kit and the iNOS expression was measured by reverse transcriptase polymerase chain reaction (RT-PCR). And proinflammatory cytokines were measured by ELISA kit. As a result, the RBE reduced NO, iNOS expression and TNF-α, IL-1β, IL-6 production without cytotoxicity. Our results suggest that the RBE may have an anti-inflammatory property through suppressing inflammatory mediator productions and appears to be useful as an anti-inflammatory material.
