Edaravone ameliorates compression-induced damage in rat nucleus pulposus cells

Edaravone is a strong free radical scavenger most used for treating acute ischemic stroke. In this study we investigated the protective effects and underlying mechanisms of edaravone on compression-induced damage in rat nucleus pulposus (NP) cells. Cell viability was determined using MTT assay methods. NP cell apoptosis was measured by Hoechst 33,258 staining and Annexin V/PI double staining. Intracellular reactive oxygen species (ROS),...
