Fig. 1From: Magnetic field distribution modulation of intrathecal delivered ketorolac iron-oxide nanoparticle conjugates produce excellent analgesia for chronic inflammatory painA brief summary of this research. The Ketorolac iron-oxide nanoparticle conjugate was synthesized and then injected into the mice spinal cords. Different magnet polarities were then applied to test the analgesic effect. The expression of COX-1 and COX-2 in the spinal cords of the mice were also checkedBack to article page
